Subject: holding down a button for repeated responding
Message-ID: <THU.5.APR.2007.100721.0400.BROBINSO@MPRC.UMARYLAND.EDU>

hi all.
i'm trying to figure out a way to interpret a held-down key as a repeated key press.

for a little background, i'm working on a flicker paradigm where a trial consists of two slides presented one after the other.  one slide has green boxes around the center, and the other has red boxes in the same locations around the center.  when presented rapidly and repeatedly, the screen appears to flicker green-red.  depending on the user's response, i adjust the redness of the red objects until the green and red objects are equiluminant (at which time you should no longer notice a flicker between the two slides).  if my red starts out as 255,0,0 (an RGB value), each Button1 press would subtract 1 from the Red value, making the new RGB value 254,0,0.  i'd like to be able to cycle rapidly all the way through the 256 different levels of Red, but 256 individual button presses is not fun.

i would like the user to be able to press and hold a keyboard button down in order to comfortably cycle through all these levels of red.  

the first time it's pressed EPrime interprets the press with no problem, but the next time it cycles through the trial, if the button is still pressed, i'd like EPrime to interpret that as an additional button press.

is there a way to check the status of the button (depressed, or extended)?  that's just one thought.  anyone have a better idea?

if anyone's interested...
i figured out a solution by adding presses and releases to the allowable responses (while presses are 1s and 2s, eprime codes releases as -1s and -2s).
then i run through the following set of if-thens at the end of each trial:

*/Dim myRed as Integer
Dim myRedRGB as String
Dim holdDown as Integer*/    'these three variables need to be pasted into the User tab of the Script window

If RedScreen.ACC = 0 Then    '(an ACC of 1 kicks you out of the loop - just press ENTER when you've found isoluminance)
	Select Case RedScreen.RESP
		Case "{LEFTARROW}"
			holdDown = 1
			If myRed > 0 Then
				myRed = myRed-1
			Else
				myRed = 255
			End If
		Case "{-LEFTARROW}"
			holdDown = 0
		Case "{RIGHTARROW}"
			holdDown = 2
			If myRed < 255 Then
				myRed = myRed+1
			Else
				myRed = 0
			End If
		Case "{-RIGHTARROW}"
			holdDown = 0
		Case Else
			Select Case holdDown
				Case 1
					If myRed > 0 Then
						myRed = myRed-1

						myRed = 255
					End If
				Case 2
					If myRed < 255 Then

	End Select

Subject: drag-and-drop with mouse?
Message-ID: <THU.19.APR.2007.133333.0500.>

Hi,

Just curious. Someone here is wondering if eprime can implement moving around bmp objects (on a slide, say) by using a mouse to click on a bmp/object, drag it to a new location on the screen, and drop in a new location. 

My present thought is to use strHit to compare a click location to a particular object on a slide, bmpX (say, defined as an attribute on a trial list) - based on a sample program at eprime downloads (response areas for mouse input). that would identify which bmp was selected. 

but instead of drag-and-drop, the subject could then click a destination location on another part of the screen - is there any way to then 'move' the selected/first-clicked-on-bmpX to the new location chosen by the second mouse click? are predefined destination locations the way to go, as in, treat the destinations as objects on a slide, too (say, 9 are allowed), and then display a different slide state to reflect the new location of bmpX?

any suggestions appreciated.
Thanks, Stephani

I would probably use in-line code to redraw the screen rather than slide 
states, just because I found that method to be so easy.

Subject: Two scenarios
Message-ID: <FRI.20.APR.2007.113942.0100.R.L.C.MITCHELL@READING.AC.UK>

Hello everybody :-)

I have 2 scenarios that I need some help setting up.
I can think of very long winded ways of doing what I need, i.e. by typing in
64x64 lines in the stimuli list, but I suspect there are experts out there
who know that it can be done much more simply.

1) I have 64 happy sentences, 64 sad sentences and 64 neutral sentences. 
Trials involve hearing 2 sentences, and judging whether they convey the same
emotion (happy followed by a different happy sentence, sad followed by sad)
or a different emotion (happy then sad, happy then neutral, sad then happy,
sad then neutral, neutral then happy, neutral then sad).
I need to make sure half my trials are same judgements and half different
judgements, without there being an easily detectable pattern, e.g. alternate
same and different all the way through.
In simple terms, how can I achieve this?

2) I have 64 sentences, and each is recorded at 7 different amplitude
levels.
During the whole task I intend to play 70 sentences.
If e.g. sentence 39 is selected by e-prime, then I need to make sure that at
some point during the task, the subject will hear all 7 versions of
sentences 39.
But, importantly, these 7 versions must be scattered randomly throughout the
trials, i.e. they must not follow each other consecutively.


I must confess I don't quite understand nesting, and have a deep-seated
phobia of in-line script!

Hoping you can help

Best wishes
Rachel

Subject: varying lengths of exposure based on responses
Message-ID: <FRI.20.APR.2007.112248.0400.SMOELLER@UMICH.EDU>

Dear Colleagues,

I'm fairly new to using e-prime, and I'm hoping someone can help me out 
with a question.

A somewhat recent paper (Aharon et al., 2001) describes a task in which 
participants are exposed to faces.  The catch is that participants 
could vary the amount of exposure they had to these faces by their 
responses.  The default length of exposure was 8s.  If they wanted the 
faces to disappear faster, they could alternate pressing the "z" and 
"x" keys.  However, if they wanted the pictures to remain on the screen 
for longer than 8s, they could alternate pressing the "n" and "m" keys.

The authors used Authorware (Macromedia) for this task.  I was 
wondering if a similar task could be performed using e-prime.

Thank you for your time!

Best regards,

Regarding point #2, I'm wondering how it is determined which sentence 
will be played 7 different times. Is it the first sentence? Because if 
it is, I might make all 64 x 3 possible questions available in an 
initial task, then use that random pick to establish which set of 6 
other sentences would be played later. I would use both nesting and 
inline code.

Supposing that from the initial list the sentence picked is Sentence39. 
Get that attribute from the response to the initial trial, and use it to 
call out a list in the next, main trial. So, Sentence39 = Amp39, say, 
where Amp39 is a list with your 6 other sentence39s in it. Amp39 is the 
value of another attribute, say [AmpList], which will be called out in 
the main trial.

Then you could set up the main trial, nesting happy, sad, & neutral 
sentences in one line that has a weight of 63. On a second item in the 
main list, nest [AmpList], and give that item and its associated list a 
value of 6. If the selection is random, you will get the additional 6 
variations of Sentence39 scattered throughout the task, along with the 
63 other sentences.

Of course if you want half the judged pairs of sentences to be the same 
and half not to be the same, you'll have to manipulate how the items are 
selected from the nested lists, because if you have three lists in the 
task, where each list has the same number of items and the same weight, 
odds are you'll get twice as many random samples that are not matched.

I'm sure there's an easy way to make this adjustment via weight and 
selection settings. Hopefully someone else on the list will jump in with 
a suggestion.

hi stephani,
 
You will require some inline script to implement drag-and-drop or other mouse operations. Note that real drag and drop operations might experience screen flickering when the drawing operations (including the background) are complex or when the computer is slow. To avoid this problem you could use two single-click operations on source and destination area’s. I’ve used the HitTest function of the slide object in several scripts to determine which area was selected. The nice thing about this is that the slide sub-objects can also be an empty slidetext subobject. (I.e. a dummy slidetext subobject to define a selectable area.) To change the position of a slide sub-object you can modify the X and Y properties of the objects before the slide is drawn.
 
However, you don’t have to use slides if you can draw the screen yourself with some inline script. An example of this approach can be found at: http://www.psy.vu.nl/download/menu/xml/eprime_script_tohx.xml

Subject: changing text while video plays on a slide in Eprime v2
Message-ID: <SAT.21.APR.2007.105629.0700.PGOLDIN@STANFORD.EDU>

Greetings Eprime community:

We are using Eprime version 2 to show a video clip of 12s duration on a 
slide that also contains a rating scale below the video object.  Thus, we 
used a slide with tow objects: a movie object and a text object.

We want to regularly update and change the text every 500ms using a loop 
syntax without interrupting the 12s video clip.  In other words, on a 
single slide, how can we refresh the text object every 500ms while letting 
the 12s video clip continue to play? The goal is to be able to collect 
continuous ratings (using the text refresh procedure where position 
indicates a rating on a scale) while subjects view a video clip.

Any and all suggestions will be greatly appreciated!!!

Thank you in advance for helping us figure this out.

philippe

Subject: varying lengths of exposure based on responses
Message-ID: <SAT.21.APR.2007.202131.0200.PAULSPOSTBUS@HOTMAIL.COM>

Hello Scott,
one way of doing this is the following (I assume you already have a simple script for displaying the stimuli):
 
Add the following declarations to the gloabal user script (menu-view-script-user tab):
 
Const ExposureDelta% = 1000Const ExposureLowLimit% = 1000Const ExposureHighLimit% = 20000
dim iExposureTime as longdim strPrevResp as string
Then, insert an inline script object to initialize the global iExposureTime variable (this would normally be at the start of a block):
 
iExposureTime = 8000
Then, insert an inline script just before the image object (called Stim in this example) to set the exposure time of the simulus object:
Stim.Duration = iExposureTime
 
Finally, insert an inline script after the stimulus object to check the response and modify the exposure time:
 
' get the response
Dim t as stringt = LCase$(Stim.RESP)
 
' check response and alternation
if t="n" And strPrevResp<>"n" Or t="m" And strPrevResp<>"m" then   iExposureTime = iExposureTime + ExposureDeltaelseif t="z" And strPrevResp<>"z" Or t="x" And strPrevResp<>"x" then   iExposureTime = iExposureTime - ExposureDeltaend if
 
'check upper and lower limits
if iExposureTime<ExposureLowLimit then   iExposureTime = ExposureLowLimitelseif iExposureTime>ExposureHighLimit then   iExposureTime = ExposureHighLimitend if
 
' remember the response to check for alternation
strPrevResp = t
 
You might consider removing the alternation test (and related code) and only use two keys because eprime will not generate repeating key presses when the key is hold-down. (Authorware will!) 
 
Hope this helps,

Subject: Nested, Discrimination Task
Message-ID: <SUN.22.APR.2007.105253.0400.>

I am using eprime to build a series of tasks related to the perception of emotional tones of voice from the presentation of sentences.
I am trying to build a discrimination task which asks the participant to listen to two consecutive sentences (sentence pairs) and then decide whether they are the 'same' or 'different'  in their emotional intonation. 
I am new to using eprime and have used the 'nested' method to do this. Below I have copied how my 'triallist' looks.
 
Weight    Procedure    Nested                       Stim1            Stim2
   1         TrialProc   HappyList, SadList      [Hsentence]  [Ssentence]
   2         TrialProc   HappyList                  [Hsentence]  [Hsentence]
   1         TrialProc   HappyList, NeutralList  [Hsentence]  [Nsentence]
   2         TrialProc   SadList                     [Ssentence]  [Ssentence]
   1         TrialProc   SadList, HappyList      [Ssentence]  [Hsentence]
   1         TrialProc   SadList, NeutralList     [Ssentence]  [Nsentence]
   1         TrialProc   NeutralList, SadList     [Nsentence]  [Ssentence]
   1         TrialProc   NeutralList, HappyList  [Nsentence]  [Hsentence]
   2         TrialProc   NeutralList                 [Nsentence]  [Nsentence]
 
The problem I am encountering is that when the participant is presented with pairs of 'same' sentences (in relation to emotional intonation), eprime is actually presenting the same sentence in relation to its content.
For example: The sad list is selected and two sentences with sad emotional tone are conveyed. The problem is that these sentences are both "The girl walked up the stairs" (i.e. same content). I am not sure how to set it up so that although both sentences are sad, eprime selects two different sad sentences (different content) from the list of sad sentences.
 
Many thanks

Dear E-Primers,

My colleague and I have been working on programming a Dual-Task experiment
on Eprime. Not much luck as of late. I hope some of you may offer some
insight as to how we should go about programming. The task(s) are as
follows:

1. Auditory task.
We will be presenting words randomly (from a wordlist) at a steady pace -
2500msec ISI between each word. The onset of response to these words will be
logged with the Voicekey function within the SRBox. If the participant fails
to respond within 2500msec, the next word will be presented .

2. Visual Task.
Participants will be making their response by hitting the <spacebar>
whenever they see a number appear on the screen. The numbers are presented
randomly by means of an inline. The duration of this visual stimuli is
250ms. Each visual stimuli is separated by a mask that lasts 900msec.

Both tasks will run simultaneously. The auditory task is allowed to reloop
in random order if the wordlist contains insufficient words to run the
duration of the visual task. The experiment will end once the visual task is
completed (approximately 30mins).

I don't think slide objects work as they do not allow the tasks to be run
and logged simultaneously and independently.

Thanks for your help!

Mark

hi Rachel,
 
I don't have the EPrime manual at hand, but I remember you will have to add indices after the nested attribute names:
   2         TrialProc   HappyList                  [Hsentence:1]  [Hsentence:2]
(Not completely sure about this syntax, so you might have to check the manual though!)

Subject: Task-switching
Message-ID: <THU.26.APR.2007.123040.0100.>

Hi,

I have designed a task-switching paradigm, involving 3 lists (one for each
task). Each list contains 9 cues and 9 stimuli, and the list the stimuli is
chosen from is chosen by a randomisation using the following code:

Dim trialarray(2) as integer	

trialarray(0) = 1
trialarray(1) = 2
trialarray(2) = 3
Randomizearray trialarray
c.Setattrib "Lag_Condition", trialarray(1)

Dim Task
Task = c.GetAttrib ("Lag_Condition")


if Task = 1 then
Borderlist.Run c
elseif Task=2 then
Angledlist.Run c
else
Shadedlist.Run c
End if

This randomises on every trial, but how do I set the code so that it remains
random, but DOES NOT ALLOW the previous list to be relevant to the current
selection? I am trying to get it so the task never repeats, but remains random.
How is this done?!?!

Many thanks!

hi all.
i'm trying to figure out a way to interpret a held-down key as a repeated key press.

for a little background, i'm working on a flicker paradigm where a trial consists of two slides presented one after the other.  one slide has green boxes around the center, and the other has red boxes in the same locations around the center.  when presented rapidly and repeatedly, the screen appears to flicker green-red.  depending on the user's response, i adjust the redness of the red objects until the green and red objects are equiluminant (at which time you should no longer notice a flicker between the two slides).  if my red starts out as 255,0,0 (an RGB value), each Button1 press would subtract 1 from the Red value, making the new RGB value 254,0,0.  i'd like to be able to cycle rapidly all the way through the 256 different levels of Red, but 256 individual button presses is not fun.

i would like the user to be able to press and hold a keyboard button down in order to comfortably cycle through all these levels of red.  

the first time it's pressed EPrime interprets the press with no problem, but the next time it cycles through the trial, if the button is still pressed, i'd like EPrime to interpret that as an additional button press.

is there a way to check the status of the button (depressed, or extended)?  that's just one thought.  anyone have a better idea?

if anyone's interested...
i figured out a solution by adding presses and releases to the allowable responses (while presses are 1s and 2s, eprime codes releases as -1s and -2s).
then i run through the following set of if-thens at the end of each trial:

*/Dim myRed as Integer

Dim holdDown as Integer*/    'these three variables need to be pasted into the User tab of the Script window

If RedScreen.ACC = 0 Then    '(an ACC of 1 kicks you out of the loop - just press ENTER when you've found isoluminance)
	Select Case RedScreen.RESP
		Case "{LEFTARROW}"
			holdDown = 1
			If myRed > 0 Then
				myRed = myRed-1
			Else
				myRed = 255

Subject: drag-and-drop with mouse?
Message-ID: <THU.19.APR.2007.133333.0500.>

Hi,

Just curious. Someone here is wondering if eprime can implement moving around bmp objects (on a slide, say) by using a mouse to click on a bmp/object, drag it to a new location on the screen, and drop in a new location. 

My present thought is to use strHit to compare a click location to a particular object on a slide, bmpX (say, defined as an attribute on a trial list) - based on a sample program at eprime downloads (response areas for mouse input). that would identify which bmp was selected. 

but instead of drag-and-drop, the subject could then click a destination location on another part of the screen - is there any way to then 'move' the selected/first-clicked-on-bmpX to the new location chosen by the second mouse click? are predefined destination locations the way to go, as in, treat the destinations as objects on a slide, too (say, 9 are allowed), and then display a different slide state to reflect the new location of bmpX?

any suggestions appreciated.
Thanks, Stephani

I would probably use in-line code to redraw the screen rather than slide 
states, just because I found that method to be so easy.

Subject: Two scenarios
Message-ID: <FRI.20.APR.2007.113942.0100.R.L.C.MITCHELL@READING.AC.UK>

Hello everybody :-)

I have 2 scenarios that I need some help setting up.
I can think of very long winded ways of doing what I need, i.e. by typing in
64x64 lines in the stimuli list, but I suspect there are experts out there
who know that it can be done much more simply.

1) I have 64 happy sentences, 64 sad sentences and 64 neutral sentences. 
Trials involve hearing 2 sentences, and judging whether they convey the same
emotion (happy followed by a different happy sentence, sad followed by sad)
or a different emotion (happy then sad, happy then neutral, sad then happy,
sad then neutral, neutral then happy, neutral then sad).
I need to make sure half my trials are same judgements and half different
judgements, without there being an easily detectable pattern, e.g. alternate
same and different all the way through.
In simple terms, how can I achieve this?

2) I have 64 sentences, and each is recorded at 7 different amplitude
levels.
During the whole task I intend to play 70 sentences.
If e.g. sentence 39 is selected by e-prime, then I need to make sure that at
some point during the task, the subject will hear all 7 versions of
sentences 39.
But, importantly, these 7 versions must be scattered randomly throughout the
trials, i.e. they must not follow each other consecutively.


I must confess I don't quite understand nesting, and have a deep-seated
phobia of in-line script!

Hoping you can help

Best wishes
Rachel

Subject: varying lengths of exposure based on responses
Message-ID: <FRI.20.APR.2007.112248.0400.SMOELLER@UMICH.EDU>

Dear Colleagues,

I'm fairly new to using e-prime, and I'm hoping someone can help me out 
with a question.

A somewhat recent paper (Aharon et al., 2001) describes a task in which 
participants are exposed to faces.  The catch is that participants 
could vary the amount of exposure they had to these faces by their 
responses.  The default length of exposure was 8s.  If they wanted the 
faces to disappear faster, they could alternate pressing the "z" and 
"x" keys.  However, if they wanted the pictures to remain on the screen 
for longer than 8s, they could alternate pressing the "n" and "m" keys.

The authors used Authorware (Macromedia) for this task.  I was 
wondering if a similar task could be performed using e-prime.

Thank you for your time!

Best regards,

Regarding point #2, I'm wondering how it is determined which sentence 
will be played 7 different times. Is it the first sentence? Because if 
it is, I might make all 64 x 3 possible questions available in an 
initial task, then use that random pick to establish which set of 6 
other sentences would be played later. I would use both nesting and 
inline code.

Supposing that from the initial list the sentence picked is Sentence39. 
Get that attribute from the response to the initial trial, and use it to 
call out a list in the next, main trial. So, Sentence39 = Amp39, say, 
where Amp39 is a list with your 6 other sentence39s in it. Amp39 is the 
value of another attribute, say [AmpList], which will be called out in 
the main trial.

Then you could set up the main trial, nesting happy, sad, & neutral 
sentences in one line that has a weight of 63. On a second item in the 
main list, nest [AmpList], and give that item and its associated list a 
value of 6. If the selection is random, you will get the additional 6 
variations of Sentence39 scattered throughout the task, along with the 
63 other sentences.

Of course if you want half the judged pairs of sentences to be the same 
and half not to be the same, you'll have to manipulate how the items are 
selected from the nested lists, because if you have three lists in the 
task, where each list has the same number of items and the same weight, 
odds are you'll get twice as many random samples that are not matched.

I'm sure there's an easy way to make this adjustment via weight and 
selection settings. Hopefully someone else on the list will jump in with 
a suggestion.

hi stephani,
 
You will require some inline script to implement drag-and-drop or other mouse operations. Note that real drag and drop operations might experience screen flickering when the drawing operations (including the background) are complex or when the computer is slow. To avoid this problem you could use two single-click operations on source and destination area?s. I?ve used the HitTest function of the slide object in several scripts to determine which area was selected. The nice thing about this is that the slide sub-objects can also be an empty slidetext subobject. (I.e. a dummy slidetext subobject to define a selectable area.) To change the position of a slide sub-object you can modify the X and Y properties of the objects before the slide is drawn.
 
However, you don?t have to use slides if you can draw the screen yourself with some inline script. An example of this approach can be found at: http://www.psy.vu.nl/download/menu/xml/eprime_script_tohx.xml

Subject: changing text while video plays on a slide in Eprime v2
Message-ID: <SAT.21.APR.2007.105629.0700.PGOLDIN@STANFORD.EDU>

Greetings Eprime community:

We are using Eprime version 2 to show a video clip of 12s duration on a 
slide that also contains a rating scale below the video object.  Thus, we 
used a slide with tow objects: a movie object and a text object.

We want to regularly update and change the text every 500ms using a loop 
syntax without interrupting the 12s video clip.  In other words, on a 
single slide, how can we refresh the text object every 500ms while letting 
the 12s video clip continue to play? The goal is to be able to collect 
continuous ratings (using the text refresh procedure where position 
indicates a rating on a scale) while subjects view a video clip.

Any and all suggestions will be greatly appreciated!!!

Thank you in advance for helping us figure this out.

philippe

Subject: varying lengths of exposure based on responses
Message-ID: <SAT.21.APR.2007.202131.0200.PAULSPOSTBUS@HOTMAIL.COM>

Hello Scott,
one way of doing this is the following (I assume you already have a simple script for displaying the stimuli):
 
Add the following declarations to the gloabal user script (menu-view-script-user tab):
 
Const ExposureDelta% = 1000Const ExposureLowLimit% = 1000Const ExposureHighLimit% = 20000
dim iExposureTime as longdim strPrevResp as string
Then, insert an inline script object to initialize the global iExposureTime variable (this would normally be at the start of a block):
 
iExposureTime = 8000
Then, insert an inline script just before the image object (called Stim in this example) to set the exposure time of the simulus object:
Stim.Duration = iExposureTime
 
Finally, insert an inline script after the stimulus object to check the response and modify the exposure time:
 
' get the response
Dim t as stringt = LCase$(Stim.RESP)
 
' check response and alternation
if t="n" And strPrevResp<>"n" Or t="m" And strPrevResp<>"m" then   iExposureTime = iExposureTime + ExposureDeltaelseif t="z" And strPrevResp<>"z" Or t="x" And strPrevResp<>"x" then   iExposureTime = iExposureTime - ExposureDeltaend if
 
'check upper and lower limits
if iExposureTime<ExposureLowLimit then   iExposureTime = ExposureLowLimitelseif iExposureTime>ExposureHighLimit then   iExposureTime = ExposureHighLimitend if
 
' remember the response to check for alternation
strPrevResp = t
 
You might consider removing the alternation test (and related code) and only use two keys because eprime will not generate repeating key presses when the key is hold-down. (Authorware will!) 
 
Hope this helps,

Subject: Nested, Discrimination Task
Message-ID: <SUN.22.APR.2007.105253.0400.>

I am using eprime to build a series of tasks related to the perception of emotional tones of voice from the presentation of sentences.
I am trying to build a discrimination task which asks the participant to listen to two consecutive sentences (sentence pairs) and then decide whether they are the 'same' or 'different'  in their emotional intonation. 
I am new to using eprime and have used the 'nested' method to do this. Below I have copied how my 'triallist' looks.
 
Weight    Procedure    Nested                       Stim1            Stim2
   1         TrialProc   HappyList, SadList      [Hsentence]  [Ssentence]
   2         TrialProc   HappyList                  [Hsentence]  [Hsentence]
   1         TrialProc   HappyList, NeutralList  [Hsentence]  [Nsentence]
   2         TrialProc   SadList                     [Ssentence]  [Ssentence]
   1         TrialProc   SadList, HappyList      [Ssentence]  [Hsentence]
   1         TrialProc   SadList, NeutralList     [Ssentence]  [Nsentence]
   1         TrialProc   NeutralList, SadList     [Nsentence]  [Ssentence]
   1         TrialProc   NeutralList, HappyList  [Nsentence]  [Hsentence]
   2         TrialProc   NeutralList                 [Nsentence]  [Nsentence]
 
The problem I am encountering is that when the participant is presented with pairs of 'same' sentences (in relation to emotional intonation), eprime is actually presenting the same sentence in relation to its content.
For example: The sad list is selected and two sentences with sad emotional tone are conveyed. The problem is that these sentences are both "The girl walked up the stairs" (i.e. same content). I am not sure how to set it up so that although both sentences are sad, eprime selects two different sad sentences (different content) from the list of sad sentences.
 
Many thanks

Dear E-Primers,

My colleague and I have been working on programming a Dual-Task experiment
on Eprime. Not much luck as of late. I hope some of you may offer some
insight as to how we should go about programming. The task(s) are as
follows:

1. Auditory task.
We will be presenting words randomly (from a wordlist) at a steady pace -
2500msec ISI between each word. The onset of response to these words will be
logged with the Voicekey function within the SRBox. If the participant fails
to respond within 2500msec, the next word will be presented .

2. Visual Task.
Participants will be making their response by hitting the <spacebar>
whenever they see a number appear on the screen. The numbers are presented
randomly by means of an inline. The duration of this visual stimuli is
250ms. Each visual stimuli is separated by a mask that lasts 900msec.

Both tasks will run simultaneously. The auditory task is allowed to reloop
in random order if the wordlist contains insufficient words to run the
duration of the visual task. The experiment will end once the visual task is
completed (approximately 30mins).

I don't think slide objects work as they do not allow the tasks to be run
and logged simultaneously and independently.

Thanks for your help!

Mark

hi Rachel,
 
I don't have the EPrime manual at hand, but I remember you will have to add indices after the nested attribute names:
   2         TrialProc   HappyList                  [Hsentence:1]  [Hsentence:2]
(Not completely sure about this syntax, so you might have to check the manual though!)

Subject: Task-switching
Message-ID: <THU.26.APR.2007.123040.0100.>

Hi,

I have designed a task-switching paradigm, involving 3 lists (one for each
task). Each list contains 9 cues and 9 stimuli, and the list the stimuli is
chosen from is chosen by a randomisation using the following code:

Dim trialarray(2) as integer	

trialarray(0) = 1
trialarray(1) = 2
trialarray(2) = 3
Randomizearray trialarray
c.Setattrib "Lag_Condition", trialarray(1)

Dim Task
Task = c.GetAttrib ("Lag_Condition")


if Task = 1 then
Borderlist.Run c
elseif Task=2 then
Angledlist.Run c
else
Shadedlist.Run c
End if

This randomises on every trial, but how do I set the code so that it remains
random, but DOES NOT ALLOW the previous list to be relevant to the current
selection? I am trying to get it so the task never repeats, but remains random.
How is this done?!?!

Many thanks!
