Subject: Multiple responses in a dual-task paradigm
Message-ID: <WED.2.SEP.2009.025342.0700.>

Hello,

at the moment I am programming a dual-task paradigm where the
secondary task consists of pressing the space bar randomly. As a
primary task the subjects are typing numbers. So I have a slide with
two keyboard input masks from which I like to grab multiple responses.
How can I save my data separately? Or in other words, how are the two
keyboard input masks called in e-Basic?

Thanks a lot for your help,

Janina

Hi all --

I've been having a hard time with the MovieDisplay object. Things seem to work OK with short movies, but I need to play a 20-min movie. A variety of bad things happen when I try to do this. For instance, midway through the movie the audio begins to lag behind the audio. If I try to have separate MovieDisplay objects, each playing a single minute of the movie, Eprime will freeze up before it reaches the end of the third minute. Has anyone had any troubles like this?

David & Peter,

Thanks so much for all the extensive guidance on my Onset Delay/
PreRelease Queries. I have successfully managed to get my OnsetDelay
down to -1 (!) thanks to using the preloading without canvas script
and without having to shrink my images or reduce their colour
resolution.

I am a happy (eprime) camper indeed.

With regards to the Event mode use of PreRelease, I can further
confirm that PreRelease does seem to work with Event mode as it did
reduce my OnsetDelay (prior to using PreLoad script).

many thanks,

R

Jeff,

For the record, do you use EP2 under Vista or XP?  MovieDisplay is 
known to have problems under Vista (just run a search on the E-Prime 
Google Group or the PST Forum to see for yourself).  No ideas if you 
still have trouble under XP.

BTW, I notice that in the E-Prime Google Group the topic "Multiple 
responses in a dual-task paradigm" got changed to "problems with long 
video files", which is where this post appears.  This makes for a 
confusing thread in the archive, making it hard for others to find 
things in the future (or am I wrong to think of this Group as a 
problem-solving aid going forward?).  Please everyone, let's avoid 
this in the future.  If you want to actually post a new question, 
please do not alter an existing unrelated thread.  Thanks.

Janina,

Ah yes, as explained in the InputMask Object topic of the online 
E-Basic Help, E-Prime only stores the results from *one* input mask 
of an object with multiple input masks.  Here is the relevant passage in full:

"When dealing with multiple InputMask objects, the rule of thumb to 
remember is that the RteRunnableInputObject's mirror properties (ACC, 
RESP, RT, RTTime, CRESP) will reflect the last mask to have processed 
a response or timed out.  Therefore, if two input masks are to be 
disarmed if the InputMask.TerminationResponse = {ENTER}, then the 
properties for the input mask that was added last to the 
InputMaskManager will have its properties reflected in the 
RteRunnableInputObject's mirror properties.  In E-Studio, the order 
that the input masks appear in the Duration/Input property page is 
the order in which they will be added to the InputMaskManager 
object.  When an input mask is disarmed as a result of another mask 
completing, it does not update its information to the 
RteRunnableInputObject's mirror properties.  For example, if the 
first mask meets its max count, then the RteRunnableInputObject 
mirror properties reflects the values in the first mask, and not the 
second, third, etc."

To save data separately, you will need some inline script.  The 
Multiple Response Collection example from the Downloads area of the 
PST web site may help you with that (you will have to register and 
login to have access to the Downloads area).

Hi everyone,

does anyone of you have experience with using ERTS key with E-Prime. I
used to work with the DOS-based ERTS for quite a long time and prefer
its response keys, there are several sizes and they are quite handy as
compared to the PST response box.

Thanks a lot,
Tobias

Subject: correct answer depending on "group" startup information
Message-ID: <FRI.4.SEP.2009.104020.0700.>

Hi everyone,

I have a question concerning the "group" variable than can be prompted
for in the beginning of each session. I want to change the correct
answer key according to this group variable (and change the key
assignment as a consequence of corse).

In a very easy example there might be a trials with a target or no
target (blank). One group should answer with "w" for TARGET and "q"
for BLANK, the other group the other way round:

LIST:

ID             Procedure   corrAns
-------------------------------
1		blank	        [no]
1		target	[yes]


I used this InLineas the very first line:

dim yes, no
if group = 1 then yes = "q" and no = "w"
if group = 2 then yes = "w" and no = "q"

Unfortunately I get the error message "Unknown function "group"".
What does that mean? I am not so familiar with Basic, so any help
might be very cool.
Maybe you have other suggestions to change key assignment by the help
of startup information.

Thanks a lot,
Tobias

Hi,

I think group is not really a variable. It  is an attribute. You will need
getattrib function. The following script probably is what you need.

if c.GetAttrib("group") = 1 then
   List1.SetAttrib 1, "corrAns", "w"
   List1.SetAttrib 2, "corrAns", "q"
else
   List1.SetAttrib 1, "corrAns", "q"
   List1.SetAttrib 2, "corrAns", "w"
end if

Best,

Shin-Yi


   List1.SetAttrib 1 "corrAns")yes = "q" and no = "w"
> if group = 2 then yes = "w" and no = "q"

Hello eprime experter,

I am a new user of eprime. I am currently developing a task called
stop signal task. But it is not easy for me to programme it using
eprime because I know little about the script.

My question is do those people who have the eprime version of the
paradigm would like to share with me?


Thanks in advance.

Hey everyone,
I’ve just started using e-prime and already have a simple question!
Im trying to create a simple experiment with randomized blocks.
My experiments consist of a learning- and test-phase. In the test
there are three blocks to complete. I would like to have e-prime
selecting the three blocks per random!
Hope you have the solution!

Deeppack,

I'm pretty sure that this is covered in Tutorial 1 of the Getting 
Started Guide that came with E-Prime, please give that a try.

I am conducting an airport luggage screening and need to tailor my

(Hit, Miss, False Alarm and Correct Rejection). Participants press Z
to indicate that weapon is present and M to indicate that there is no
weapon present.
Hit: Z Z (Correct Response/ User Response)
Miss: Z M
False Alarm: M Z
Correct Rejection: M M

I have no idea how to write script. Please help. Thanks

Patricia,

First off, if you really have no idea how to write script, then you 
*must* pause here and work through Chapter 4 of the User's Guide that 
came with E-Prime.  I can wait...

... OK, did you *really* stop and work through Chapter 4?  Then let us 
proceed ...


You might do this with a simple TextDisplay object, or Text sub-objects 
within a slide, or you might go whole hog and use a Slide with multiple 
states.

To use a text object, just use an attribute reference for your feedback 
text, e.g., [myFeedback]

Then add a bit of inline script between your response object and your 
feedback object to assign a value to myFeedback.  Suppose we call your 
response object ResponseText, and it uses the attribute CorrectKey for 
the correct response, then your script might look like this:

If ResponseText.RESP = "Z" Then
     If ResponseText.CRESP = "Z" Then c.SetAttrib "myFeedback", "Hit"
     Else c.SetAttrib "myFeedback", "Miss"
Else
     If ResponseText.CRESP = "Z" Then c.SetAttrib "myFeedback", "FA"
     Else c.SetAttrib "myFeedback", "Correct Rejection"
End If

Or if you prefer, you can do this using the correct response scoring 
built in to E-Prime:
If ResponseText.CORR Then
     If ResponseText.RESP = "Z" Then c.SetAttrib "myFeedback", "Hit"
     Else c.SetAttrib "myFeedback", "Correct Rejection"
Else
     If ResponseText.RESP = "Z" Then c.SetAttrib "myFeedback", "FA"
     Else c.SetAttrib "myFeedback", "Miss"
End If

Finally, at the risk of some obfuscation, you could make use of the 
Iif() function to compact this to:
If ResponseText.CORR Then
     c.SetAttrib "myFeedback", Iif( ResponseText.RESP = "Z", "Hit", 
"Correct Rejection" )
Else
     c.SetAttrib "myFeedback", Iif( ResponseText.RESP = "Z", "FA", "Miss" )
End If

It's really up to you and your programming style.


You could instead do this with a Slide with multiple states, one state 
each for Hit, Miss, False Alarm, and Correct Rejection.  Then you might 
keep all the slide text and design static, and just flip the state 
depending on the response.  I can only give a sketch of how to approach 
this.  First, to learn more about using Slides I would look through the 
manuals that came with E-Prime, and browse through the Slide topic in 
the online E-Basic Help (unfortunatley, I did not find any "Slide with 
multiple states" sample on the PST web site, perhaps they could add 
one?).  Then to really understand how to script this and how to invoke 
the separate slide states, I would create a Slide with multiple states 
and then look at the script that E-Prime generates for me.  In fact I 
figure out a lot of things in E-Prime just by looking at the script that 
E-Prime generates for me.


I have used a number of terms here that may be new to you (Iif, 
SetAttrib, etc.), in general to learn more about these please look in 
the online E-Basic Help.

Subject: Inline for calling feedback screen in unreferenced objects
Message-ID: <WED.9.SEP.2009.113805.0700.>

Dear colleagues,

I am having a strange problem using an inline code that refers to a
TextDisplay in unreferenced objects.

First I had a feedback TextDisplay between two blocklists (to show
mean performance after blocks) and it worked fine with these Inlines:

(1. Summation reset)
Set g_theSummationP = New Summation
Set g_theSummationPRT = New Summation

(2. summation each trial)
g_theSummationP.AddObservation mask2.Acc
g_theSummationPRT.AddObservation mask2.RT

(3. variable setting)
c.SetAttrib "BlockAccuracyP", Format(CStr(CDbl(g_theSummationP.Mean *
100)), "0.00")
c.SetAttrib "BlockRTP", Format(CStr(CDbl(g_theSummationPRT.Mean )),
"0.00")

And then there was Feedback (TextDisplay) with this content:
"Your result:

Mean Reaction Time:
[BlockRTP] ms

Correctness:
[BlockAccuracyP]%"


Well, that worked fine, I got feedback after each block. Now I wanted
Feedback more often, not only after blocklists, but after 48 trials.
So I used this Inline:

If c.GetAttrib(c.GetAttrib("Running") & ".Sample")  MOD 48 = 0 Then
	c.SetAttrib "BlockAccuracyP", Format(CStr(CDbl(g_theSummationP.Mean *
100)), "0.00")
	c.SetAttrib "BlockRTP", Format(CStr(CDbl(g_theSummationPRT.Mean )),
"0.00")
	TextDisplay2.InputMasks.Add Keyboard.CreateInputMask("{ANY}", "", CLng
(TextDisplay2.Duration), CLng("1"), ebEndResponseActionTerminate,
CLogical("Yes"), "", "", "ResponseMode:All ProcessBackspace:Yes")
	TextDisplay2.Run
	Set g_theSummationP = New Summation
	Set g_theSummationPRT = New Summation
	Set g_theSummationS = New Summation
	Set g_theSummationSRT = New Summation
End If


TextDisplay was in unreferenced objects. I was already using this
"trick" to insert a break (break display in unreferenced objects) in
order to have a break every X trials, independent of blocks etc.

Now what I get is that it is actually calling TextDisplay2 (which is
the feedback) but the screen is blank (that is no text, only
background can be seen). If I leave away the variables
[BlockAccuracyP] and [BlockRTP] it is working, though! Do I need to
specify variables in the inline when they are used in displays that
are in the unreferenced objects? If yes, how?

Thank you very much for you patience and potential help!
Cheers,
Tobias

Hi again,

doing some more work on this strange E-Prime behaviour, I found out
that every Inline, calling for an objects (no matter if elsewhere in
the program or in unreferenced objects) will cause the object to show
only the background and no text as long as some variable or attribute
(in square brackets) is embedded in the text. So it seems to be a
general problem. Still, maybe some of you know a solution...

Not sure I understand what the problem is, but maybe try something 
like this to set the FeedBack text?:

Dim urrt, uracc As Single
urrt = c.GetAttrib "BlockRTP"
uracc = c.GetAttrib "BlockAccuracyP"
Dim str1, str2 As String
str1 = "Your Result: " & vbCrLf & vbCrLf & "Mean Reaction Time: " 
&  urrt & " ms"   & vbCrLf & vbCrLf
str2 = "Correctness: " &  uracc & "%"
TextDisplay2.Text =  str1 & str2

If not use \n instead:

Subject: End a for loop early in ebasic?
Message-ID: <FRI.11.SEP.2009.141303.0400.>

Hello all,

I have a program in e-basic that takes two arrays and combines them, then
randomizes and recombines them. Since I can't reuse any combinations that
were in place previously, I have a loop structure in place to detect whether
the combinations have been used. It goes something like this.

HeadColor(7) As String
HeadShape(7) As String
(takes values for each)
For a = 0 to a = 7
 Heads(a) = HeadColor(a) + HeadShape(a)

/*randomize and check for repeats
Nomatch As Boolean
Nomatch = false
Matches As Integer

While Nomatch = false
 Randomize HeadColor
 Randomize HeadShape
* For b = 0 to b = 7
  If HeadColor(b) + HeadShape(b) = Heads(b)
   Matches = Matches + 1*
  End If
  Next b
 If Matches = 0
  Nomatch = true
Wend

Now -- in the highlighted FOR loop, if the If statement is true, it is
basically saying that the entire While loop needs to be repeated and
re-randomized (a match is present). Thus, the rest of the For loop is
irrelevant. Is there a statement that can be used to end the for loop, like
a break or end statement?

Also, if my code is horribly inefficient, feel free to critique me as I'm
not a trained programmer.

Any help would be appreciated! Thanks!

Adam

Subject: Displaying The Information Within An Array
Message-ID: <FRI.11.SEP.2009.114631.0700.>

Hello,
     I am new to E Prime but I have had a little experience with other
programming languages.  Currently, I am trying to fill an array with
information and then display the information from a particular trial
number at the end of that trial.  However, when I run the program I
get an error when it goes to display the information (on the feedback
screen) from the array.  The code looks like the following:
You made [Hits(TrialNumber)] hits.
You made [Misses(TrialNumber)] misses.
You made [FalseAlarms(TrialNumber)] false alarms.

Can anyone help me set this up correctly or provide a source for more
information?  Any help would be appreciated!  Thanks in advance!

Adam,

You may use Exit For to get out of a For loop early, please see the 
"Exit (keyword)" topic in the E-Basic online help and take it from there.

On a style note, for some reason even young E-Prime programmers seem 
to latch on to the quaint and long deprecated While...Wend statement 
instead of using the much more serviceable and preferred Do...Loop 
construct (please see, e.g., 
http://msdn.microsoft.com/en-us/library/661sy9w2(VS.85).aspx ).  I 
would ask everyone to abandon While...Wend in favor of Do...Loop; 
While...Wend went out with the Commodore 64!

Finally, as in PST's NoRepeat.es example, you use a non-deterministic 
algorithm instead of a deterministic algorithm.  I have discussed 
this elsewhere.  But a deterministic algorithm, though arguably more 
efficient, takes some intricate programming, and your sample size is 
so small that I do not think it worth the effort.  So I would have 
you continue with what you are doing.

McGree,

I assume that "You made [...]" is text from your feedback Text or 
Slide object.  In that case you must learn that between the square 
brackets you must enter an "attribute reference", you may not use an 
actual variable there (an easy bit of confusion when coming to 
E-Prime from other programming systems).  So you will need to change 
your feedback Text or Slide to something like

You made [Hits] hits.
You made [Misses] misses.
You made [FalseAlarms] false alarms.

And then in script before your feedback Text or Slide you might do 
something like

c.SetAttrib "Hits", Hits(TrialNumber)
c.SetAttrib "Misses", Misses(TrialNumber)
c.SetAttrib "FalstAlarms", FalseAlarms(TrialNumber)

(Note, BTW, that variables and attribute references may have the same name.)

For more info, you might start with the Context Object topic in the 
online E-Basic Help.  In general, the online E-Basic Help is the real 
documentation for E-Prime.

Hope this helps,

Subject: Thread Error - Sound Buffer
Message-ID: <TUE.15.SEP.2009.060813.0700.>

Hi All,

I'm running an experiment that requires participants to listen to an
auditory question and then respond following three beeps.  The program
runs fine during the first trial and then crashes during the second
trial with the following error message:

"Unable to communicate with thread that fills the sound buffer
contents
Extra1: 320000
Extra2: 0
Extra3: 421250
Extra4: No
Extra 5: 2696

Error Number: -999"

I'm running E-Prime v.2 on Windows XP.  All of the .wav files are
recorded as 16bit 22050Hz in stereo. The auditory question files are
between 70 and 90KB in size and the beep file is 5KB.

I'd be grateful if anyone has any insights in how to address this
problem.

Many Thanks,

Debra Malpass

Message-ID: <TUE.15.SEP.2009.143433.0400.>

Well, I discovered I made a mistake in this reply, once again 
illustrating that no one should take my word for anything!  As it 
turns out, E-Prime does have a mechanism for performing secondary 
actions or script during sound playback, and perhaps even movie 
playback.  I was only thinking about what happens with a SoundOut 
object or sub-object placed directly in the structure.  But as 
explained in the online E-Basic Help, you may do this with some 
inline script.  In particular, SoundOut.Play will begin 
*asynchronous* sound playback, i.e., the sound file "begins playing 
and then program execution continues with the next object in the 
procedure."  This would allow you to start your playback in script 
and then go on to run more script to manage TMS pulses, etc. while 
the sound continued to play.  By contrast, SoundOut.Run (which is 
what happens when you just use the SoundOut object in the structure) 
begins *synchronous* sound playback, i.e., "Run does not return until 
the execution of all of the object is done."

One would think that the new MovieDisplay object would have similar 
properties and methods to the SoundOut object, but so far PST has not 
provided any documentation.  And we already know that MovieDisplay 
lacks a Loop property, in contrast to the SoundOut object (see 
http://support.pstnet.com/forum/Topic2772-12-1.aspx ), so I would not 
make any bets.

Just wanted to correct the record, my apologies.

Subject: Set the timing to record RT?
Message-ID: <TUE.15.SEP.2009.210119.0700.>

Dear all,

I'm still a rookie in E-Prime and designing an ABX discrimination
task. I got a question about the timing to record RT. Does anyone know
how to set the timing to record RT in E-Studio 2.0? I looked up the
user's guide and it says that RT is always recorded from the onset of
the response logging event. However, this is not the way I want. I
need to record RT right AFTER subject has heard the audio stimuli. I
tried two different methods, but none of them gave me accurate RTs.

The first thing I tried was making the sound object itself as the
response logging event, but in that case, RT would be measured from
the onset of the event, which was BEFORE the whole sound file has been
played to the subject and the RT would include the duration of the
sound "file", which was way longer than subject's actual response.

The second thing I tried was adding a "Wait" object which records RT
AFTER the sound object. The duration of the sound object was set to
1500ms, but given that the length of sound files were all different,
the wait object didn't immediately start right after the sound "file"
was played. Rather, the wait object started after the whole 1500ms of
sound object had elapsed. Now the problem is that subject may already
start responding before the whole 1500ms has elapsed, so some parts of
RT will be missing since subject starts responding before the wait
object which records RT starts. So, does anyone have any idea to
record RT right after the sound "file" has been played to the
subject?

Thank you in advance for your great help!!

maybe something like this would work (or maybe not..): use 'dummy' 
object (a text object, duration = 0, wait for response = forever; 
response action = jump to label) just before sound object, to collect 
RT. There is a sample experiment on e-prime samples which illustrates 
this, maybe someone remembers its name? Is it CollectInputDuringInLine?

Log onset time of dummy. Log offset time of sound object. Compute 
adjustRT = sound offset - dummy onset. After RT is collected, compute 
realRT = dummy.RT - adjustRT . Set realRT as attribute.

Message-ID: <WED.16.SEP.2009.150445.1000.>

You say you're new to e-prime. Using dummy object, something like 
this in an inline before the end of a trial would log true RT from 
sound offset:

dumOnset = c.GetAttrib("dummy.OnsetTime")
dumRT = c.GetAttrib("dummy.RT")
soundOffset = c.GetAttrib("soundObject.OffsetTime")
adjustRT = soundOffset - dumOnset
realRT = dumRT - adjustRT
c.SetAttrib "ReactionTime",  realRT

maybe something like this would work (or maybe not..): use 'dummy' 
object (a text object, duration = 0, wait for response = forever; 
response action = jump to label) just before sound object, to collect 
RT. There is a sample experiment on e-prime samples which illustrates

Thank you,

that works fine. Unfortunately, in my real experiment (this example
was kept simple due to comprehensiveness) I don't have 2 lines in my
list but 640. I guess there is an easier way than using 640*2 lines in
this InLine. If I understand correctly, "List1.SetAttrib 1" changes
the first line in the list and "List1.SetAttrib 2" changes the second
line.

That means, that the CorrAns value is replaced (see http://chilion.com/probl1.JPG
) no matter if [yes] or [no] was specified. In fact in my real
experiment I also have only two variables. Easiest would be to change
[yes] to let's say "D" and [no] to "F" if c.GetAttrib("group") = 1 and
the other way round if it's 2.

Is that possible?

Thanks already in advance!

Cheers,
Tobias

I think I posted a reply to this thread (I wrote one for sure ^.^) but
it doesn't show up... my guess is that I hit 'reply to author' by
accident, but I can't find a record of that anywhere. Tobias, if you
didn't receive mail from me, let me know, then I'll repost (right now
I am a bit lazy to do so... it's time for me to go home...).

Have a good evening everyone!

Martin,

What if you set the End Sound Action of your SoundOut object to 
Terminate?  Wouldn't that end the SoundOut as soon as your sound file 
ended (before the 1500 ms Duration of the SoundOut object) and then 
go on to collect your RT from there?

Hi Patricia,

This should be simple. Declare a global variable 'Dim misses as
integer'. At the start of the script, misses = 0. In an inline after
the slide object, 'If slide1.ACC = "0" then misses = misses  + 1'. At
the end you can then have a feedback with 'you have lost [misses]
amount of points'

I hope this answers your question,
Tim

Hi all,

I am trying to do a New/Old procedure. If the participant responds
"New" I want the New/Old procedure to continue with the next stimulus
presentation. However, if the participant responds "Old" I want a
Context procedure to run that will allow the participant to respond
that it was seen in context "A" or context "B." After this I want the
next stimuli from the New/Old procedure to continue.

Thank you!

Hi,
So, what is your question? How far did you get? Did you get stuck anywhere? 
It seems to me you're more familiar with other types of programming than e-prime - it makes less sense in E-Prime to make "procedures" the fundamental object which you would then call from dozens of lines of script. Instead of trying to do something like procedure.exit, you might try List.terminate instead, though, or (easier, I think) use a couple of jump labels.
Say, you have a procedure with 
TextDisplay1, allowable input no (n)ew or (o)ld
An inline with 'if TextDisplay1.RESP = "n" then goto AfterContextQuestion'
TextDisplay2, "was it seen in context A or B?"
AfterContextQuestion
TextDisplay3, "thanks for the response" (whatever)

Of course, if you want, you can make it yourself difficult and do some inlining, with a loop until the participant says 'new', doing some textdisplay.run and/or calling various subs you declared beforehand. People here can do very ingenious things, and no doubt can come up with better ideas than mine here, but I'd suggest being a bit more specific and less schematic then. Do you, for instance, really want that E-Prime "runs a Context procedure", or is your aim that the participant will see this or that?

Subject: Response which leads to continuation of a procedure or starts another procedure


Hi all,

I am trying to do a New/Old procedure. If the participant responds
"New" I want the New/Old procedure to continue with the next stimulus
presentation. However, if the participant responds "Old" I want a
Context procedure to run that will allow the participant to respond
that it was seen in context "A" or context "B." After this I want the
next stimuli from the New/Old procedure to continue.

Thank you!

Subject: problem with short ISI
Message-ID: <MON.21.SEP.2009.102850.0700.>

I have a vowel discrimination task (vowels are 50 ms each) that I've
been presenting at several ISIs (as low as 40 ms and as long as 1500
ms). All of these ISIs have been correctly logged (subtracting slide
onset of the blank screen from the onset of the second vowel).  I have
it set up to play a sound object, have a blank screen for the duration
of the specified ISI, and then the second sound object. (I have the
ISI blank screen set to preload at 100 ms and the sounds are set to
'streaming'. Also, I'm running 2.0 Pro on an XP machine). When I
changed the duration of the blank screen to 10 ms I got actual
durations from 27 to 40 ms. I've tried adding a preload of 50 to the
second sound object and have also tried to reduce the preload on the
blank screen to 50 ms and these have not helped.

Thanks in advance!
Susie

Missing a small step here, as you cannot directly use a variable as 
an attribute reference in your feedback display.  So just before your 
feedback display add a bit more inline script like

c.SetAttrib "misses", misses

(Note that variables and context attributes may have the same name.)

See the Context topic in the online E-Basic Help for more details.

Susie,

Thanks for all the wonderful detail, I wish I had a good answer for 
you!  Just a couple thoughts...

First, can you add a PreRelease to the first sound object?  That 
might allow some time for your ISI blank screen to get set up (I 
don't think the PreRelease on the second sound object does anything 
for you).  Do keep the PreRelease on your ISI as long as 
feasible.  (When I use PreRelease I usually go ahead and make it as 
long as the Duration, or even longer, say 10000.  It doesn't seem to 
matter (short of terminating with a response, etc.), which makes 
sense if you think about what PreRelease really does under the covers.)

Second, as you remember from Chapter 3 of the User's Guide, take a 
look at the Onset and Offset Sync of your ISI blank screen.  If you 
sync with the vertical blank then you will have delays due to waiting 
for the screen to refresh, so you may want to turn that off.  OTOH, 
without syncing to vertical blank you may get brief visual artifacts 
as your blank screen goes on or off.  Just an unavoidable limitation 
of our current technology.

Hi David, Susie,
On the second point, you might, if you are using a CRT screen, change
the resolution and refresh rate in your windows monitor options. In the
past, it happened quite a lot that discrepancies here between E-Prime
(1) and windows screen options would lead to refresh rates that were
different from what they were supposed to be. Check your edat file to
see what your refresh rate was during the experiment. Also, I don't
think ISIs of 10 ms with LCD screens are possible, if you happen to be
using that (the fastest refresh rates I've seen in that department were
around 70 Hz - 14ms), unless you want half of your screen refreshed at
some point.

David and Mich,

Thanks so much. I had forgotten about the refresh rate (I am on and
LCD monitor) and you're right, my refresh rate (which I'd checked at
the very beginning of running things) was about 70 Hz. I actually
don't have that many pairings so I think I'll just manually create
single sound files with a 10 ms period of silence.

I'll try the pre-release of the first element, but given the
limitations of the refresh rate, I"m guessing that it won't help.

Thanks,
Susie

Hi,
I recently used your answer to Leslie to design a similar experiment,
but I ran into a curious result. Whenever the participant responds
"new" and the context slide (TextDisplay2, in this example) is
skipped, e-prime records that a response has been given which is the
same as the last response given to a context slide. So, for example, a
subject might respond old, A, new, (skipped slide--it records A), new
(it records A), old, B, new, (it records B), old, B, new (it records
B). So that the response column for the context slide that should look
like A, 0, 0, B, 0, B, 0, looks like A, A, A, B, B, B, B.
Why would it record a response when the slide wasn't shown? I can
obviously delete any responses that occur on trials that the subject
responded "new," but that is an extra step that I'd like to avoid.
Thanks for any help!
Lauren

Dear all,

I am trying to introduce a break in the list of trials. Say, after 20
trials, a text display comes introducing a break. After a response
from the participant, experiment should resume from the same place
where it left. Does some body has a piece of code to share? Any
suggestions are well appreciated.

You can do that really easily without any coding.

Construct a list. Have all of your test trials come up during a given
procedure, like say TrialProc.

Set the TrialProc's weight to 20 for 20 repetitions.

In level 2 of the list, come up with a break procedure called BreakProc (or
whatever you want to call it) that contains the break. If you want to resume
the trials after the break, for level 3 set TrialProc as the procedure.

It sometimes happens however, that your desired number of trials
inbetween breaks does not correspond with the number of trials in your
triallist (I took this code for instance from a task with 36 trials in
one triallist that is repeated 8 times, and I wanted breaks every 20
trials).

You can do the following:

at the end of the trailproc add three consecutive elements:
- an inline
- a slide or textdisplay that is 'the break'
- a label called skiplabel

The inline should contain the following code:
---------------------------------------
          trialcounter = trialcounter + 1

           if trialcounter mod 20 = 0 then

           else goto skiplabel
           end if
--------------------------------------
For this code to work you also need to paste the following " dim
trialcounter as integer " on the usertab of the scriptwindow (remove
the " s).
If you use one single triallist (I don't in this case) you can also
remove the first line (trialcounter= trialcounter +1) and then replace
trialcounter mod 20 by triallist.sample mod 20 (triallist being the
name of your triallist).

What it does: a trialcounter keeps track of the number of trials. If
the number of trials can be divided by 20 (so: 20, 40, 80, 100 etc)
then nothing will happen and the program will follow the proc. As the
inline is followed by the breakslide, the breakslide will show. If the
number of trials can not be divided by 20, e-prime will immediately
'goto' the skiplabel and as that is placed after the breakslide, the
breakslide will be 'skipped'.


Best regards,

liwenna

liwenna,

Thanks for a nice explanation of this alternative method.  Please 
note that the lines

if trialcounter mod 20 = 0 then
else goto skiplabel
end if

could be simplified to just

If (trialcounter mod 20) <> 0 Then Goto skiplabel

(I also added capitalization and parentheses just to suit my style).

Subject: Multiple responses in a dual-task paradigm
Message-ID: <WED.2.SEP.2009.025342.0700.>

Hello,

at the moment I am programming a dual-task paradigm where the
secondary task consists of pressing the space bar randomly. As a
primary task the subjects are typing numbers. So I have a slide with
two keyboard input masks from which I like to grab multiple responses.
How can I save my data separately? Or in other words, how are the two
keyboard input masks called in e-Basic?

Thanks a lot for your help,

Janina

Hi all --

I've been having a hard time with the MovieDisplay object. Things seem to work OK with short movies, but I need to play a 20-min movie. A variety of bad things happen when I try to do this. For instance, midway through the movie the audio begins to lag behind the audio. If I try to have separate MovieDisplay objects, each playing a single minute of the movie, Eprime will freeze up before it reaches the end of the third minute. Has anyone had any troubles like this?

David & Peter,

Thanks so much for all the extensive guidance on my Onset Delay/
PreRelease Queries. I have successfully managed to get my OnsetDelay
down to -1 (!) thanks to using the preloading without canvas script
and without having to shrink my images or reduce their colour
resolution.

I am a happy (eprime) camper indeed.

With regards to the Event mode use of PreRelease, I can further
confirm that PreRelease does seem to work with Event mode as it did
reduce my OnsetDelay (prior to using PreLoad script).

many thanks,

R

Jeff,

For the record, do you use EP2 under Vista or XP?  MovieDisplay is 
known to have problems under Vista (just run a search on the E-Prime 
Google Group or the PST Forum to see for yourself).  No ideas if you 
still have trouble under XP.

BTW, I notice that in the E-Prime Google Group the topic "Multiple 
responses in a dual-task paradigm" got changed to "problems with long 
video files", which is where this post appears.  This makes for a 
confusing thread in the archive, making it hard for others to find 
things in the future (or am I wrong to think of this Group as a 
problem-solving aid going forward?).  Please everyone, let's avoid 
this in the future.  If you want to actually post a new question, 
please do not alter an existing unrelated thread.  Thanks.

Janina,

Ah yes, as explained in the InputMask Object topic of the online 
E-Basic Help, E-Prime only stores the results from *one* input mask 
of an object with multiple input masks.  Here is the relevant passage in full:

"When dealing with multiple InputMask objects, the rule of thumb to 
remember is that the RteRunnableInputObject's mirror properties (ACC, 
RESP, RT, RTTime, CRESP) will reflect the last mask to have processed 
a response or timed out.  Therefore, if two input masks are to be 
disarmed if the InputMask.TerminationResponse = {ENTER}, then the 
properties for the input mask that was added last to the 
InputMaskManager will have its properties reflected in the 
RteRunnableInputObject's mirror properties.  In E-Studio, the order 
that the input masks appear in the Duration/Input property page is 
the order in which they will be added to the InputMaskManager 
object.  When an input mask is disarmed as a result of another mask 
completing, it does not update its information to the 
RteRunnableInputObject's mirror properties.  For example, if the 
first mask meets its max count, then the RteRunnableInputObject 
mirror properties reflects the values in the first mask, and not the 
second, third, etc."

To save data separately, you will need some inline script.  The 
Multiple Response Collection example from the Downloads area of the 
PST web site may help you with that (you will have to register and 
login to have access to the Downloads area).

Subject: Using ERTS keys in E-Prime
Message-ID: <FRI.4.SEP.2009.043009.0700.>

Hi everyone,

does anyone of you have experience with using ERTS key with E-Prime. I
used to work with the DOS-based ERTS for quite a long time and prefer
its response keys, there are several sizes and they are quite handy as
compared to the PST response box.

Thanks a lot,
Tobias

Subject: correct answer depending on "group" startup information
Message-ID: <FRI.4.SEP.2009.104020.0700.>

Hi everyone,

I have a question concerning the "group" variable than can be prompted
for in the beginning of each session. I want to change the correct
answer key according to this group variable (and change the key
assignment as a consequence of corse).

In a very easy example there might be a trials with a target or no
target (blank). One group should answer with "w" for TARGET and "q"
for BLANK, the other group the other way round:

LIST:

ID             Procedure   corrAns
-------------------------------
1		blank	        [no]
1		target	[yes]


I used this InLineas the very first line:

dim yes, no
if group = 1 then yes = "q" and no = "w"
if group = 2 then yes = "w" and no = "q"

Unfortunately I get the error message "Unknown function "group"".
What does that mean? I am not so familiar with Basic, so any help
might be very cool.
Maybe you have other suggestions to change key assignment by the help
of startup information.

Thanks a lot,
Tobias

Hi,

I think group is not really a variable. It  is an attribute. You will need
getattrib function. The following script probably is what you need.

if c.GetAttrib("group") = 1 then
   List1.SetAttrib 1, "corrAns", "w"
   List1.SetAttrib 2, "corrAns", "q"
else
   List1.SetAttrib 1, "corrAns", "q"
   List1.SetAttrib 2, "corrAns", "w"
end if

Best,

Shin-Yi


   List1.SetAttrib 1 "corrAns")yes = "q" and no = "w"
> if group = 2 then yes = "w" and no = "q"

Message-ID: <MON.7.SEP.2009.022733.0700.>

Hello eprime experter,

I am a new user of eprime. I am currently developing a task called
stop signal task. But it is not easy for me to programme it using
eprime because I know little about the script.

My question is do those people who have the eprime version of the
paradigm would like to share with me?


Thanks in advance.

Hey everyone,
I?ve just started using e-prime and already have a simple question!
Im trying to create a simple experiment with randomized blocks.
My experiments consist of a learning- and test-phase. In the test
there are three blocks to complete. I would like to have e-prime
selecting the three blocks per random!
Hope you have the solution!

Message-ID: <TUE.8.SEP.2009.173611.0400.>

Patricia,

First off, if you really have no idea how to write script, then you 
*must* pause here and work through Chapter 4 of the User's Guide that 
came with E-Prime.  I can wait...

... OK, did you *really* stop and work through Chapter 4?  Then let us 
proceed ...


You might do this with a simple TextDisplay object, or Text sub-objects 
within a slide, or you might go whole hog and use a Slide with multiple 
states.

To use a text object, just use an attribute reference for your feedback 
text, e.g., [myFeedback]

Then add a bit of inline script between your response object and your 
feedback object to assign a value to myFeedback.  Suppose we call your 
response object ResponseText, and it uses the attribute CorrectKey for 
the correct response, then your script might look like this:

If ResponseText.RESP = "Z" Then
     If ResponseText.CRESP = "Z" Then c.SetAttrib "myFeedback", "Hit"
     Else c.SetAttrib "myFeedback", "Miss"
Else
     If ResponseText.CRESP = "Z" Then c.SetAttrib "myFeedback", "FA"
     Else c.SetAttrib "myFeedback", "Correct Rejection"
End If

Or if you prefer, you can do this using the correct response scoring 
built in to E-Prime:
If ResponseText.CORR Then
     If ResponseText.RESP = "Z" Then c.SetAttrib "myFeedback", "Hit"
     Else c.SetAttrib "myFeedback", "Correct Rejection"
Else
     If ResponseText.RESP = "Z" Then c.SetAttrib "myFeedback", "FA"
     Else c.SetAttrib "myFeedback", "Miss"
End If

Finally, at the risk of some obfuscation, you could make use of the 
Iif() function to compact this to:
If ResponseText.CORR Then
     c.SetAttrib "myFeedback", Iif( ResponseText.RESP = "Z", "Hit", 
"Correct Rejection" )
Else
     c.SetAttrib "myFeedback", Iif( ResponseText.RESP = "Z", "FA", "Miss" )
End If

It's really up to you and your programming style.


You could instead do this with a Slide with multiple states, one state 
each for Hit, Miss, False Alarm, and Correct Rejection.  Then you might 
keep all the slide text and design static, and just flip the state 
depending on the response.  I can only give a sketch of how to approach 
this.  First, to learn more about using Slides I would look through the 
manuals that came with E-Prime, and browse through the Slide topic in 
the online E-Basic Help (unfortunatley, I did not find any "Slide with 
multiple states" sample on the PST web site, perhaps they could add 
one?).  Then to really understand how to script this and how to invoke 
the separate slide states, I would create a Slide with multiple states 
and then look at the script that E-Prime generates for me.  In fact I 
figure out a lot of things in E-Prime just by looking at the script that 
E-Prime generates for me.


I have used a number of terms here that may be new to you (Iif, 
SetAttrib, etc.), in general to learn more about these please look in 
the online E-Basic Help.

Subject: Inline for calling feedback screen in unreferenced objects
Message-ID: <WED.9.SEP.2009.113805.0700.>

Dear colleagues,

I am having a strange problem using an inline code that refers to a
TextDisplay in unreferenced objects.

First I had a feedback TextDisplay between two blocklists (to show
mean performance after blocks) and it worked fine with these Inlines:

(1. Summation reset)
Set g_theSummationP = New Summation
Set g_theSummationPRT = New Summation

(2. summation each trial)
g_theSummationP.AddObservation mask2.Acc
g_theSummationPRT.AddObservation mask2.RT

(3. variable setting)
c.SetAttrib "BlockAccuracyP", Format(CStr(CDbl(g_theSummationP.Mean *
100)), "0.00")
c.SetAttrib "BlockRTP", Format(CStr(CDbl(g_theSummationPRT.Mean )),
"0.00")

And then there was Feedback (TextDisplay) with this content:
"Your result:

Mean Reaction Time:
[BlockRTP] ms

Correctness:
[BlockAccuracyP]%"


Well, that worked fine, I got feedback after each block. Now I wanted
Feedback more often, not only after blocklists, but after 48 trials.
So I used this Inline:

If c.GetAttrib(c.GetAttrib("Running") & ".Sample")  MOD 48 = 0 Then
	c.SetAttrib "BlockAccuracyP", Format(CStr(CDbl(g_theSummationP.Mean *
100)), "0.00")
	c.SetAttrib "BlockRTP", Format(CStr(CDbl(g_theSummationPRT.Mean )),
"0.00")
	TextDisplay2.InputMasks.Add Keyboard.CreateInputMask("{ANY}", "", CLng
(TextDisplay2.Duration), CLng("1"), ebEndResponseActionTerminate,
CLogical("Yes"), "", "", "ResponseMode:All ProcessBackspace:Yes")
	TextDisplay2.Run
	Set g_theSummationP = New Summation
	Set g_theSummationPRT = New Summation
	Set g_theSummationS = New Summation
	Set g_theSummationSRT = New Summation
End If


TextDisplay was in unreferenced objects. I was already using this
"trick" to insert a break (break display in unreferenced objects) in
order to have a break every X trials, independent of blocks etc.

Now what I get is that it is actually calling TextDisplay2 (which is
the feedback) but the screen is blank (that is no text, only
background can be seen). If I leave away the variables
[BlockAccuracyP] and [BlockRTP] it is working, though! Do I need to
specify variables in the inline when they are used in displays that
are in the unreferenced objects? If yes, how?

Thank you very much for you patience and potential help!
Cheers,
Tobias

Subject: Inline for calling feedback screen in unreferenced objects

Hi again,

doing some more work on this strange E-Prime behaviour, I found out
that every Inline, calling for an objects (no matter if elsewhere in
the program or in unreferenced objects) will cause the object to show
only the background and no text as long as some variable or attribute
(in square brackets) is embedded in the text. So it seems to be a
general problem. Still, maybe some of you know a solution...

Not sure I understand what the problem is, but maybe try something 
like this to set the FeedBack text?:

Dim urrt, uracc As Single
urrt = c.GetAttrib "BlockRTP"
uracc = c.GetAttrib "BlockAccuracyP"
Dim str1, str2 As String
str1 = "Your Result: " & vbCrLf & vbCrLf & "Mean Reaction Time: " 
&  urrt & " ms"   & vbCrLf & vbCrLf
str2 = "Correctness: " &  uracc & "%"
TextDisplay2.Text =  str1 & str2

...oh. not sure if e-basic accepts &vbCrLf as line space character. 
If not use \n instead:

Rest.text = "Thank you."&_
"\n" &_
"Take a rest now, and relax your eyes."&_
"\n" &_
"\n" &_

Subject: End a for loop early in ebasic?
Message-ID: <FRI.11.SEP.2009.141303.0400.>

Hello all,

I have a program in e-basic that takes two arrays and combines them, then
randomizes and recombines them. Since I can't reuse any combinations that
were in place previously, I have a loop structure in place to detect whether
the combinations have been used. It goes something like this.

HeadColor(7) As String
HeadShape(7) As String
(takes values for each)
For a = 0 to a = 7
 Heads(a) = HeadColor(a) + HeadShape(a)

/*randomize and check for repeats
Nomatch As Boolean
Nomatch = false
Matches As Integer

While Nomatch = false
 Randomize HeadColor
 Randomize HeadShape
* For b = 0 to b = 7
  If HeadColor(b) + HeadShape(b) = Heads(b)
   Matches = Matches + 1*
  End If
  Next b
 If Matches = 0
  Nomatch = true
Wend

Now -- in the highlighted FOR loop, if the If statement is true, it is
basically saying that the entire While loop needs to be repeated and
re-randomized (a match is present). Thus, the rest of the For loop is
irrelevant. Is there a statement that can be used to end the for loop, like
a break or end statement?

Also, if my code is horribly inefficient, feel free to critique me as I'm
not a trained programmer.

Any help would be appreciated! Thanks!

Adam

Subject: Displaying The Information Within An Array
Message-ID: <FRI.11.SEP.2009.114631.0700.>

Hello,
     I am new to E Prime but I have had a little experience with other
programming languages.  Currently, I am trying to fill an array with
information and then display the information from a particular trial
number at the end of that trial.  However, when I run the program I
get an error when it goes to display the information (on the feedback
screen) from the array.  The code looks like the following:
You made [Hits(TrialNumber)] hits.
You made [Misses(TrialNumber)] misses.
You made [FalseAlarms(TrialNumber)] false alarms.

Can anyone help me set this up correctly or provide a source for more
information?  Any help would be appreciated!  Thanks in advance!

Adam,

You may use Exit For to get out of a For loop early, please see the 
"Exit (keyword)" topic in the E-Basic online help and take it from there.

On a style note, for some reason even young E-Prime programmers seem 
to latch on to the quaint and long deprecated While...Wend statement 
instead of using the much more serviceable and preferred Do...Loop 
construct (please see, e.g., 
http://msdn.microsoft.com/en-us/library/661sy9w2(VS.85).aspx ).  I 
would ask everyone to abandon While...Wend in favor of Do...Loop; 
While...Wend went out with the Commodore 64!

Finally, as in PST's NoRepeat.es example, you use a non-deterministic 
algorithm instead of a deterministic algorithm.  I have discussed 
this elsewhere.  But a deterministic algorithm, though arguably more 
efficient, takes some intricate programming, and your sample size is 
so small that I do not think it worth the effort.  So I would have 
you continue with what you are doing.

McGree,

I assume that "You made [...]" is text from your feedback Text or 
Slide object.  In that case you must learn that between the square 
brackets you must enter an "attribute reference", you may not use an 
actual variable there (an easy bit of confusion when coming to 
E-Prime from other programming systems).  So you will need to change 
your feedback Text or Slide to something like

You made [Hits] hits.
You made [Misses] misses.
You made [FalseAlarms] false alarms.

And then in script before your feedback Text or Slide you might do 
something like

c.SetAttrib "Hits", Hits(TrialNumber)
c.SetAttrib "Misses", Misses(TrialNumber)
c.SetAttrib "FalstAlarms", FalseAlarms(TrialNumber)

(Note, BTW, that variables and attribute references may have the same name.)

For more info, you might start with the Context Object topic in the 
online E-Basic Help.  In general, the online E-Basic Help is the real 
documentation for E-Prime.

Hope this helps,

Subject: Thread Error - Sound Buffer
Message-ID: <TUE.15.SEP.2009.060813.0700.>

Hi All,

I'm running an experiment that requires participants to listen to an
auditory question and then respond following three beeps.  The program
runs fine during the first trial and then crashes during the second
trial with the following error message:

"Unable to communicate with thread that fills the sound buffer
contents
Extra1: 320000
Extra2: 0
Extra3: 421250
Extra4: No
Extra 5: 2696

Error Number: -999"

I'm running E-Prime v.2 on Windows XP.  All of the .wav files are
recorded as 16bit 22050Hz in stereo. The auditory question files are
between 70 and 90KB in size and the beep file is 5KB.

I'd be grateful if anyone has any insights in how to address this
problem.

Many Thanks,

Debra Malpass

Subject: tms pulse during video playing

Message-ID: <TUE.15.SEP.2009.143433.0400.>

Well, I discovered I made a mistake in this reply, once again 
illustrating that no one should take my word for anything!  As it 
turns out, E-Prime does have a mechanism for performing secondary 
actions or script during sound playback, and perhaps even movie 
playback.  I was only thinking about what happens with a SoundOut 
object or sub-object placed directly in the structure.  But as 
explained in the online E-Basic Help, you may do this with some 
inline script.  In particular, SoundOut.Play will begin 
*asynchronous* sound playback, i.e., the sound file "begins playing 
and then program execution continues with the next object in the 
procedure."  This would allow you to start your playback in script 
and then go on to run more script to manage TMS pulses, etc. while 
the sound continued to play.  By contrast, SoundOut.Run (which is 
what happens when you just use the SoundOut object in the structure) 
begins *synchronous* sound playback, i.e., "Run does not return until 
the execution of all of the object is done."

One would think that the new MovieDisplay object would have similar 
properties and methods to the SoundOut object, but so far PST has not 
provided any documentation.  And we already know that MovieDisplay 
lacks a Loop property, in contrast to the SoundOut object (see 
http://support.pstnet.com/forum/Topic2772-12-1.aspx ), so I would not 
make any bets.

Just wanted to correct the record, my apologies.

Subject: Set the timing to record RT?
Message-ID: <TUE.15.SEP.2009.210119.0700.>

Dear all,

I'm still a rookie in E-Prime and designing an ABX discrimination
task. I got a question about the timing to record RT. Does anyone know
how to set the timing to record RT in E-Studio 2.0? I looked up the
user's guide and it says that RT is always recorded from the onset of
the response logging event. However, this is not the way I want. I
need to record RT right AFTER subject has heard the audio stimuli. I
tried two different methods, but none of them gave me accurate RTs.

The first thing I tried was making the sound object itself as the
response logging event, but in that case, RT would be measured from
the onset of the event, which was BEFORE the whole sound file has been
played to the subject and the RT would include the duration of the
sound "file", which was way longer than subject's actual response.

The second thing I tried was adding a "Wait" object which records RT
AFTER the sound object. The duration of the sound object was set to
1500ms, but given that the length of sound files were all different,
the wait object didn't immediately start right after the sound "file"
was played. Rather, the wait object started after the whole 1500ms of
sound object had elapsed. Now the problem is that subject may already
start responding before the whole 1500ms has elapsed, so some parts of
RT will be missing since subject starts responding before the wait
object which records RT starts. So, does anyone have any idea to
record RT right after the sound "file" has been played to the
subject?

Thank you in advance for your great help!!

-Martin

maybe something like this would work (or maybe not..): use 'dummy' 
object (a text object, duration = 0, wait for response = forever; 
response action = jump to label) just before sound object, to collect 
RT. There is a sample experiment on e-prime samples which illustrates 
this, maybe someone remembers its name? Is it CollectInputDuringInLine?

Log onset time of dummy. Log offset time of sound object. Compute 
adjustRT = sound offset - dummy onset. After RT is collected, compute 
realRT = dummy.RT - adjustRT . Set realRT as attribute.

You say you're new to e-prime. Using dummy object, something like 
this in an inline before the end of a trial would log true RT from 
sound offset:

dumOnset = c.GetAttrib("dummy.OnsetTime")
dumRT = c.GetAttrib("dummy.RT")
soundOffset = c.GetAttrib("soundObject.OffsetTime")
adjustRT = soundOffset - dumOnset
realRT = dumRT - adjustRT
c.SetAttrib "ReactionTime",  realRT

maybe something like this would work (or maybe not..): use 'dummy' 
object (a text object, duration = 0, wait for response = forever; 
response action = jump to label) just before sound object, to collect 
RT. There is a sample experiment on e-prime samples which illustrates

Thank you,

that works fine. Unfortunately, in my real experiment (this example
was kept simple due to comprehensiveness) I don't have 2 lines in my
list but 640. I guess there is an easier way than using 640*2 lines in
this InLine. If I understand correctly, "List1.SetAttrib 1" changes
the first line in the list and "List1.SetAttrib 2" changes the second
line.

That means, that the CorrAns value is replaced (see http://chilion.com/probl1.JPG
) no matter if [yes] or [no] was specified. In fact in my real
experiment I also have only two variables. Easiest would be to change
[yes] to let's say "D" and [no] to "F" if c.GetAttrib("group") = 1 and
the other way round if it's 2.

Is that possible?

Thanks already in advance!

Cheers,
Tobias

I think I posted a reply to this thread (I wrote one for sure ^.^) but
it doesn't show up... my guess is that I hit 'reply to author' by
accident, but I can't find a record of that anywhere. Tobias, if you

Yes, you could use a For...Next loop.

Martin,

What if you set the End Sound Action of your SoundOut object to 
Terminate?  Wouldn't that end the SoundOut as soon as your sound file 
ended (before the 1500 ms Duration of the SoundOut object) and then 
go on to collect your RT from there?

Hi Patricia,

This should be simple. Declare a global variable 'Dim misses as
integer'. At the start of the script, misses = 0. In an inline after
the slide object, 'If slide1.ACC = "0" then misses = misses  + 1'. At
the end you can then have a feedback with 'you have lost [misses]
amount of points'

I hope this answers your question,
Tim

Hi,
So, what is your question? How far did you get? Did you get stuck anywhere? 
It seems to me you're more familiar with other types of programming than e-prime - it makes less sense in E-Prime to make "procedures" the fundamental object which you would then call from dozens of lines of script. Instead of trying to do something like procedure.exit, you might try List.terminate instead, though, or (easier, I think) use a couple of jump labels.
Say, you have a procedure with 
TextDisplay1, allowable input no (n)ew or (o)ld
An inline with 'if TextDisplay1.RESP = "n" then goto AfterContextQuestion'
TextDisplay2, "was it seen in context A or B?"
AfterContextQuestion
TextDisplay3, "thanks for the response" (whatever)

Of course, if you want, you can make it yourself difficult and do some inlining, with a loop until the participant says 'new', doing some textdisplay.run and/or calling various subs you declared beforehand. People here can do very ingenious things, and no doubt can come up with better ideas than mine here, but I'd suggest being a bit more specific and less schematic then. Do you, for instance, really want that E-Prime "runs a Context procedure", or is your aim that the participant will see this or that?
Best,
Michiel

Subject: problem with short ISI
Message-ID: <MON.21.SEP.2009.102850.0700.>

I have a vowel discrimination task (vowels are 50 ms each) that I've
been presenting at several ISIs (as low as 40 ms and as long as 1500
ms). All of these ISIs have been correctly logged (subtracting slide
onset of the blank screen from the onset of the second vowel).  I have
it set up to play a sound object, have a blank screen for the duration
of the specified ISI, and then the second sound object. (I have the
ISI blank screen set to preload at 100 ms and the sounds are set to
'streaming'. Also, I'm running 2.0 Pro on an XP machine). When I
changed the duration of the blank screen to 10 ms I got actual
durations from 27 to 40 ms. I've tried adding a preload of 50 to the
second sound object and have also tried to reduce the preload on the
blank screen to 50 ms and these have not helped.

Thanks in advance!
Susie

Missing a small step here, as you cannot directly use a variable as 
an attribute reference in your feedback display.  So just before your 
feedback display add a bit more inline script like

c.SetAttrib "misses", misses

(Note that variables and context attributes may have the same name.)

See the Context topic in the online E-Basic Help for more details.

Susie,

Thanks for all the wonderful detail, I wish I had a good answer for 
you!  Just a couple thoughts...

First, can you add a PreRelease to the first sound object?  That 
might allow some time for your ISI blank screen to get set up (I 
don't think the PreRelease on the second sound object does anything 
for you).  Do keep the PreRelease on your ISI as long as 
feasible.  (When I use PreRelease I usually go ahead and make it as 
long as the Duration, or even longer, say 10000.  It doesn't seem to 
matter (short of terminating with a response, etc.), which makes 
sense if you think about what PreRelease really does under the covers.)

Second, as you remember from Chapter 3 of the User's Guide, take a 
look at the Onset and Offset Sync of your ISI blank screen.  If you 
sync with the vertical blank then you will have delays due to waiting 
for the screen to refresh, so you may want to turn that off.  OTOH, 
without syncing to vertical blank you may get brief visual artifacts 
as your blank screen goes on or off.  Just an unavoidable limitation 
of our current technology.

Hi David, Susie,
On the second point, you might, if you are using a CRT screen, change
the resolution and refresh rate in your windows monitor options. In the
past, it happened quite a lot that discrepancies here between E-Prime
(1) and windows screen options would lead to refresh rates that were
different from what they were supposed to be. Check your edat file to
see what your refresh rate was during the experiment. Also, I don't
think ISIs of 10 ms with LCD screens are possible, if you happen to be
using that (the fastest refresh rates I've seen in that department were
around 70 Hz - 14ms), unless you want half of your screen refreshed at
some point.

David and Mich,

Thanks so much. I had forgotten about the refresh rate (I am on and
LCD monitor) and you're right, my refresh rate (which I'd checked at
the very beginning of running things) was about 70 Hz. I actually
don't have that many pairings so I think I'll just manually create
single sound files with a 10 ms period of silence.

I'll try the pre-release of the first element, but given the
limitations of the refresh rate, I"m guessing that it won't help.

Thanks,
Susie

Subject: Response which leads to continuation of a procedure or starts
 another procedure

Hi,
I recently used your answer to Leslie to design a similar experiment,
but I ran into a curious result. Whenever the participant responds
"new" and the context slide (TextDisplay2, in this example) is
skipped, e-prime records that a response has been given which is the
same as the last response given to a context slide. So, for example, a
subject might respond old, A, new, (skipped slide--it records A), new
(it records A), old, B, new, (it records B), old, B, new (it records
B). So that the response column for the context slide that should look
like A, 0, 0, B, 0, B, 0, looks like A, A, A, B, B, B, B.
Why would it record a response when the slide wasn't shown? I can
obviously delete any responses that occur on trials that the subject
responded "new," but that is an extra step that I'd like to avoid.
Thanks for any help!
Lauren

TextDisplay1, allowable input no (n)ew or (o)ld
An inline with 'if TextDisplay1.RESP = "n" then goto
AfterContextQuestion'
TextDisplay2, "was it seen in context A or B?"

Instead of trying to do something like procedure.exit, you might try List.terminate instead, though, or (easier, I think) use a couple of jump labels.

People here can do very ingenious things, and no doubt can come up with better ideas than mine here, but I'd suggest being a bit more specific and less schematic then. Do you, for instance, really want that E-Prime "runs a Context procedure", or is your aim that the participant will see this or that?

Subject: Introducing break
Message-ID: <MON.28.SEP.2009.130346.0700.>

Dear all,

I am trying to introduce a break in the list of trials. Say, after 20
trials, a text display comes introducing a break. After a response
from the participant, experiment should resume from the same place
where it left. Does some body has a piece of code to share? Any
suggestions are well appreciated.

You can do that really easily without any coding.

Construct a list. Have all of your test trials come up during a given
procedure, like say TrialProc.

Set the TrialProc's weight to 20 for 20 repetitions.

In level 2 of the list, come up with a break procedure called BreakProc (or
whatever you want to call it) that contains the break. If you want to resume
the trials after the break, for level 3 set TrialProc as the procedure.

Subject: Introducing break
In-Reply-To: <aa7b3453-d69f-4284-85f8-5fabe7a38835@v36g2000yqv.googlegroups.com>
Message-ID: <TUE.29.SEP.2009.053727.0700.>

It sometimes happens however, that your desired number of trials
inbetween breaks does not correspond with the number of trials in your
triallist (I took this code for instance from a task with 36 trials in
one triallist that is repeated 8 times, and I wanted breaks every 20
trials).

You can do the following:

at the end of the trailproc add three consecutive elements:
- an inline
- a slide or textdisplay that is 'the break'
- a label called skiplabel

The inline should contain the following code:
---------------------------------------
          trialcounter = trialcounter + 1

           if trialcounter mod 20 = 0 then

           else goto skiplabel
           end if
--------------------------------------
For this code to work you also need to paste the following " dim
trialcounter as integer " on the usertab of the scriptwindow (remove
the " s).
If you use one single triallist (I don't in this case) you can also
remove the first line (trialcounter= trialcounter +1) and then replace
trialcounter mod 20 by triallist.sample mod 20 (triallist being the
name of your triallist).

What it does: a trialcounter keeps track of the number of trials. If
the number of trials can be divided by 20 (so: 20, 40, 80, 100 etc)
then nothing will happen and the program will follow the proc. As the
inline is followed by the breakslide, the breakslide will show. If the
number of trials can not be divided by 20, e-prime will immediately
'goto' the skiplabel and as that is placed after the breakslide, the
breakslide will be 'skipped'.


Best regards,

liwenna

liwenna,

Thanks for a nice explanation of this alternative method.  Please 
note that the lines

if trialcounter mod 20 = 0 then
else goto skiplabel
end if

could be simplified to just

If (trialcounter mod 20) <> 0 Then Goto skiplabel

(I also added capitalization and parentheses just to suit my style).
