Subject: Using and Modifying a VAS
Message-ID: <TUE.1.JUL.2014.085812.0700.>

Hello,

First, let me thank Paul Groot for creating and posting his visual analog 
scale.

Second, I am trying to modify it for my purposes. The primary challenge is 
that it was written in E-Prime 1.0, and I use 2.0. When 2.0 opens it, I 
cannot access the script. E-Prime buries the script, at least so that I 
cannot find it and thenceforth modify it.

In my pilot, I have two blocks. The first presents in random order a jpg to 
be rated on the same screen as the VAS. (Easy and done!) The second 
presents again in random order the jpg in a slide prior to the VAS; i.e., 
the VAS will be alone on the screen with the prompt question. Copying and 
pasting Groot's three key objects into another procedure (so that E-Prime 
adds a "1" to the end of their names) results in a crash upon running it, 
given that the script, I deduce, references objects by name. Having the 
same objects in two different procedures, such as in Groot's example file, 
however, means that the second time around, the jpg is shown both before 
the VAS slide and on the VAS slide as well.

Does somebody know a solution... how to access Groot's hidden-by-EPrime 
script so that I can change the objects' names for the second block? how to 
insert an object that will cover the photo in the second run-through, even? 
some other solution?

Thank you!

Humbly,

Chris

P.S. I tried accessing Groot's website since I downloaded the VAS some 
months ago, for I seem to remember the script file being there. However, 
the protections on my server are blocking it, saying it is now blacklisted 
by DNS.

Hi Chris,

I'm not aware of being blacklisted anywhere, but I will attach the EP2 VAS
example script and package to this email. The version-2 script uses an
eprime package to simplify importing the code in your own scripts. You will
need to use the PackageFile editor of EP2 to open/edit the embedded
scripts. I'm not sure if that will be required, because the name of the Vas
slide can be specified as argument in the InitVas package call. (You will
have to edit this after copy-pasting. I think the example script shows 3
different Slide objects) However, feel free to edit the code provided
inside the VAS package.

Best,
Paul

Hi David,

I'm already using the procedure you said. I have a master list as a top 
layer for two procedures Control and WM each having a weight of 30 with 
random selection. Each procedure has a sub list with 30 of trials namely 
Control & WM Trial List. Each sub list has a trial procedure with and 
without condition. The randome

I am supposed to get random trial from this setup, which I believe am 
getting but I am not sure about that. Due to the usage of IFIS paradigm 
design wizard, the trial run does not completes all 60 trails. It only runs 
for random 17 trials and asks for continuing or end the trial. It restarts 
the trial cycle if I continue or ends. I'm not sure how do I cope with this 
situation. Any suggestions would be quite helpful. 

Best Regards,
Dilip

Dilip,

I'm not sure that we're talking about the same thing.  You refer to 
three Lists, a master List with two sub-Lists.  I am talking about 
only one List that has rows for both types of trials, differentiated 
by what Procedure you put in the Procedure column of each row.  Does 
that make any sense?

As for the rest...  You use IFIS, eh?  Sigh.  Don't get me started on 
IFIS, we used that mess years ago and were glad to discard it, we 
just do straight E-Prime now and are happier for it.  So I do not 
care to sink my mind into all the IFIS nuances just now.  But I do 
recall that IFIS puts a few control Lists down in Unreferenced 
E-Objects, and you have to pay close attention to those because some 
of those values will override the control values up in your E-Prime 
design.  (Unless, of course, you have some newer and nicer version of 
IFIS that I do not know about.)  (And if you search the group for 
"IFIS", you may find further statements from me at 
https://groups.google.com/d/topic/e-prime/8e1YmtDQVNY .)

Hi there,

Has anyone experienced this type of error before? It happens when I try to 
open some files that have previously worked fine. I haven't made any 
changes to the files in the mean time, it's just that now they won't open 
and I get this message. They're pretty simple experiments too so I can't 
think what this refers to.

Thanks in advance,

Adele

Thank you for your help. The network at where I work has a strange

inexplicable reasons.

Ok thanks Paul,

I had never seen the use of &H to convert from ascii to hexadecimal. 
that makes things pretty clear.

Paul,

So this method would send the binary equivalent of those hex values which 
represent ascii characters.

Do you know if/how Serial.WriteBytes is different from Serial.Write?

I would assume that either way the information is going to be sent in the 
form of bytes through the port. Is the protocol for how e-prime sends bytes 
different for one method vs. the other.
Or is WriteBytes the same as Write except one takes hexadecimal values and 
one the other takes string values then converts them to bytes?

Any wisdom you could pass on would be much appreciated once again.

Cheers,

J

Subject: Converging trials with and without conditions into one Trial
 List...!!!
In-Reply-To: <53b420ff.255d320a.5554.7ff4SMTPIN_ADDED_MISSING@gmr-mx.google.com>
Message-ID: <WED.9.JUL.2014.182438.0700.>

Dear David,

I was suggested by an Engineer to mix these two trial list and converge 
them into one and only one list which is not possible because both the 
tasks have different trial structure and conditions. I had to assign each 
task with one procedure separately as you mentioned below.

Yes unfortunately our collaborator uses quite old version of tools and we 
have to do the same. We have to use IFIS and E-prime 1.1 on Windows XP OS 
to design our experiment.
I'm getting the random trials as desired and can run the complete trial 
list on E.prime 2.0 version but different is the case for IFIS. The 
complete task runs around 10 to 12 minutes and I can run it only 3 to 4 
minutes on IFIS based system. I have just learned that their scanner cannot 
run fMRI longer than 4 minutes continuously due to the larger size of the 
data and takes a 2 minutes break after every 4 minutes of fMRI run. I 
suspect that might be the reason for my problem. I'm trying to resolve this 
issue with their technical team.
The only solution i can foresee is to break the task into small runs.

Thanks for getting back to me on this issue. Any feedback on this will be 
strongly welcomed

Best Regards,
Dilip

Subject: Sending non-printable ascii characters via serial port
In-Reply-To: <36c2a30d-db0a-48b1-8e64-187a18b92292@googlegroups.com>
Message-ID: <THU.10.JUL.2014.102742.0200.>

Well, I'm not sure about the SerialDevice.Write function because that one
is not documented (does it really exist?) But you're right, at the end of
the story all data is exchanged as sequence of bytes; one byte at the time.
(Together with the configured start-, stop and parity bits, but that is
completely transparent to the programmer once the device is open for use.)
So, PST added a few useful wrapper functions to do the conversion to and
from bytes automatically for a few frequently used data types. Those
functions make it possible to send and receive text strings, 2 byte
integers and 4 byte integers, by calling one of the wrapper functions. On
the lower level, this conversion is pretty straightforward because the
internal (in-memory) representation of this data is already a sequence of
bytes. However, things become confusing for most people when ASCII
characters have to be translated to their numerical representation, and
vice versa. Especially when the text contains numbers. But that is
something you already figured out. (I'm just ignoring multi-byte character
sets for the moment, because that's even more challenging.)

A similar thing is true for the way numerical data is represented in
E-Basic. A numerical value can be represented by E-Basic in several ways:
decimal, hexadecimal, ... It's just the textual presentation in the script
that is different; once the value is stored in memory their is no
difference in the byte values. The &Hxx syntax is mainly available for our
convenience; to make life easier when dealing with binary data. In theory
it would have been possible to add support for a binary representation in
E-Basic, but unfortunately that is not available. But no matter what the
textual representation is, at the end it is just another byte in memory.
Regarding this point, you might also have a look at the Asc() and Chr()
functions. These functions will convert characters type to numerical type
(and back), without changing the value in-memory. This allows you to write
Asc("@") instead of &H40 or 64.

Hope this helps to understand the (seemingly) subtle, but important
differences.

Paul

Subject: Minimum trial length before termination response is allowed
Message-ID: <THU.10.JUL.2014.120912.0700.>

Hi all--first time posting here.

My question is, I am running an experiment in which subjects have to type 
1-word answers per trial.  

The time limit of each trial is unlimited as intended.

Subjects are instructed to press "ENTER" after finishing typing; this 
advances to the next trial.

However, I would like to add the following:

   - Is it possible for there to be a minimum trial duration before 
   pressing "ENTER" terminates the trial?
   - OR, is it possible for there to be a minimum number of letters (e.g., 
   3) typed before the trial can be terminated?

We have had subjects press "ENTER" reflexively without typing anything, and 
I was wondering if there was some sort of inline script that could be added 
to prevent this.

Thanks for any suggestions!

Subject: Question about setting up a wav file to repeat throughout
 experiment
Message-ID: <THU.10.JUL.2014.191847.0700.>

Hi all, 

First off thank you for setting up this group - it's been a lot of help 
reading through.

I'm having some trouble figuring out how to make a sound file repeat itself 
every certain amount of seconds in EP1. Basically, I want to set this loop 
to play a beep in the background while other things are going on (stimuli 
being presented on the screen). I would need the sound to repeat itself 
during most of the experiment and was thinking that instead of ending the 
loop during the intermittent times I need it not to play, I would just mute 
the sound output (if possible from E-Prime) during these sections and just 
resume it after the section is completed.

What would you all recommend as the best way of succeeding this? 

Thank you in advance for all the help.

Hi Semeon,

Instead of using an inline, it should be possible (and easier) to define
the duration as attribute at the blocklevel list. (I think that would be
TalkerList in your script).
Just add an attribute to the list (i.e. *RespDuration*) and use this
attribute name as duration value in Response->Duration by using the square
bracket reference method: *[RespDuration]*.
EPrime will then use the duration values defined in the list for each block.

Best,
Paul

Subject: Upload two different images with different contingencies
 (reversal)
Message-ID: <MON.14.JUL.2014.010645.0700.>

Hi everyone,
 
I started a few weeks ago with e-prime and I can run basic experiments but 
I have to make a reversal task to start as soon as possible with my study 
and I am struggling with this task so I will be very grateful if you guys 
can help me with this. Thank you.
The experiment consists in two figures where one of those is correct most 
of the times and receive feedback when selecting it (the feedback, smiley 
face has to appear while the two figures are still on the screen), then 
fixation and another trial with the same figures but in different locations 
(right/left vs left/right). After that the contingencies reversed  after  6 
to 10 choices of the highly rewarded stimulus. Well, this would be the 
first step, but I got stuck uploading each figure and giving them the 
proper contingencies, which the correct figure would result in reward on 
80% of trials while the incorrect one would be rewarded on 20%. Any help is 
more than welcome, thanks in advanced.
 
Best,
Nata

 experiment

Hi,

Did you succeed yet?

I thought this wasn’t possible, actually, thinking that whatever you create the sound object as will be permanent. But, not so; the sounddevice itself (turn on sound device in experiment settings, will create global “sound” object) can be adjusted. For example, if you have a soundout object (let’s call it soundout1, and make it play windows critical stop or some such, set it to loop, turn on volume control, and delete it/make it unreferenced), this will work:

 

Dim i As Integer

soundout1.Play 

For i = -10000 To 0 Step 100

      sound.Volume = i

      debug.print i

      sleep 100

Next i

sleep 2000

 

It looks better if you use a dual monitor setup and check the debug screen.

Hope that helps.

Best,

Michiel

Subject: Question about setting up a wav file to repeat throughout experiment

 

Hi all, 

First off thank you for setting up this group - it's been a lot of help reading through.

I'm having some trouble figuring out how to make a sound file repeat itself every certain amount of seconds in EP1. Basically, I want to set this loop to play a beep in the background while other things are going on (stimuli being presented on the screen). I would need the sound to repeat itself during most of the experiment and was thinking that instead of ending the loop during the intermittent times I need it not to play, I would just mute the sound output (if possible from E-Prime) during these sections and just resume it after the section is completed.

What would you all recommend as the best way of succeeding this? 

Thank you in advance for all the help.

Subject: Loading one attribute from a list
Message-ID: <MON.14.JUL.2014.084935.0700.>

Hello to everyone,

I know how to load a complete list from a text file. However, I have now a 
difficult problem: I would like to load only ONE attribute from a text 
file. I know I could generate the whole list and load all of it, but it 
would be better for the design of the experiment to generate most of the 
list property from within e-prime and generate one attribute from outside. 
Is this possible?
Thank you very much,
Valerio

Valerio,

Try removing the attribute from your main List, and for each level of 
your main List add a nested List, say, LoadList.  Then load your 
nested LoadList from a text file in the usual way.  For each trial, 
E-Prime will take all the attributes from one row of your main List, 
plus the added attribute from the nested LoadList, which in turn came 
from your external text file.

Hope that helps.

Hello,

I am building an experiment in which answers should be recorderd. It is a 
naming test: a picture will be shown on the screen and the participant is 
asked to name it. I am having some trouble in recording the answers. I have 
watched some e-prime tutorials and so far what I understood from the videos 
is that I must have a serial response box in order to record the answer and 
control the response time. My question is, is this the only option to 
record anwers in e-prime?

Please work through all the tutorials in all of the manuals that come

keyboard, record vocal responses to sound files from the microphone, etc.

Subject: Spacebar presses increases after every reward
Message-ID: <THU.17.JUL.2014.112431.0700.>

Hi there,

I apologize in advance for being naive with E-Prime scripting and inline 
scripting.  I want to create an experiment where a participants needs to 
press the spacebar multiple times for a reward. For example, first they 
press two times on the spacebar then get the reward, then they press four 
times then get the reward, then 8 times, and so forth... Since I know I'm 
not reinventing the wheel here, I'm sure someone has looked at this... 
would anyone know if there is a sample out there investigating this? Any 
help would be appreciated! 

Thanks in advance!

Hi Natalia,

I'd need more information from you to be able to advise.

What IS working and what IS NOT working? (e.g. image display; detection of 
mouse click on images,...)

Do you get an error message (what) or does it just not work how you want it 
to work?

John

It sounds like you are trying to build a probabilistic selection experiment 
similar to the one described in a paper by Frank, Seeberger, and O'Reily 
(2004), where ...
 
  1. The participant is instructed to choose which object is "correct".  
  2. The objects (stimuli) are chosen in pairs (AB, CD, EF, ...) and 
displayed at random.  But it seems like you want to have them permanently 
set to one side (?). 
  3. Feedback is given after each trial for each condition. The object is 
"Correct" either 80%, 70%, and 60% of the time and "Incorrect" either 20%, 
30% and 40% of the time.
 
Is this right?  Following John's response, where in your design are you 
having issues?
 
Thanks,
 
David

Hi!
 
Thanks a lot for your help. As an e-prime beginner I'd like to do the task 
step by step even though what I want to achieve as a result is what David 
described in his response. I would like to know how can I put two different 
images in the same slide and give them a different correct response 
depending if it is the right or the left image, How this would look like in 
the list and procedure?. The second part is that I need a feedback for the 
correct and incorrect response but I'd need that this feedback comes up 
while the images are still on the screen. Thank you very much for your help.
 
Cheers,
Natalia

Subject: Presenting a trial at a specific trial number while randomizing
 the rest
Message-ID: <TUE.22.JUL.2014.110659.0700.>

I'm currently working on an experiment where I have 478 random trials and 
then 2 extremely different trials (we'll call Trial A and B). Ideally, I 
would like for the 478 trials to be presented at random and Trial A to be 
presented after 250 random trials and then Trial B to be presented after 
350 random trials. My inline script looks like:

g_nTotalTrial = g_nTotalTrial+1
c.SetAttrib "TrialCount", g_nTotalTrial

If "TrialCount" = "2" Then 
c.SetAttrib "RightCue", "Shape.bmp"
Else 
End If

Trial A and B is supposed to show a different image as the right cue 
(Shape.bmp and Color.bmp respectively). Although I don't get any errors 
running the experiment, Trial A and B are not presented at Trial 250 and 
350. 
**Note that this was just a trial run where I used the trial counter as 2 
and only have Trial A.

Subject: "swirling circle" remains on screen while program is running
Message-ID: <TUE.22.JUL.2014.144752.0700.>

Hi all, 

I'm having an issue with the "swirling circle" remaining on the screen 
throughout the entire time that a program is running. 
By "swirling circle", I refer to the loading icon (replaces the hourglass) 
that is used in Windows 7+.
If it is relevant: 
This is an E-Prime 2 Production Release program.
I have confirmed this to happen on both a Dell and an Asus laptop.
I have confirmed that the mouse device is unchecked in the experiment 
properties. 

Thoughts?  Is this a known bug?   My next strategy would be to fiddle with 
the Windows settings, but if there's something I can fix in E-Prime, I'd 
prefer to do that.

Thanks!

By default, the mouse device is *enabled* (checked), and the 'show cursor'
setting is set to disabled. If you disable the mouse device, EPrime will
leave it as-is and Windows is in control of its shape and visibility.

Message-ID: <WED.23.JUL.2014.123229.0100.>

it's really too general a question for me to answer in a short amount of
time.

If you're a beginner I'd suggest you download and study some of the sample
files on the PST website - see here -
http://www.pstnet.com/support/samples.asp - run them through, see what they
do and then look at the source code to see how it's done.

to get you started, for your varying correct responses, you probably want a
column in your TrialList to store your correct response - eg 'corr_resp'
and then on the properties dialog  for your slide you can put the column
name in the correct response field but enclose it in square brackets e.g.
[corr_resp]

you just need to  populate the triallist table with the appropriate values
to correspond with the images that you'l show. Hopefully you can hard code
these. If not then you can populate the triallist at runtime but that
starts to get tricky for beginners.

Subject: Exact start time
Message-ID: <THU.24.JUL.2014.044422.0700.>

Hi all,

I'm working on an integration of E-Prime 2 Standard edition with an EEG 
signal recorder, and I found a problem with time measurement:

With E-Prime I can see the start time once the experiment is finished in 
the E-Data for example, but it comes with the format "dd/mm/yyyy HH:MM:SS". 
The problem is that I need to know milliseconds of start time too or the 
experiment won't worth it at all.

I looked at Now() and Time$, and both return a Date object with the 
previous format.

Trying to find a solution I though that maybe if I use 
      myDate = DateAdd("s",3,Now()) 
and after it
      While Now()  < myDate
      Wend
I could force the start 3 seconds later, but after test it I realized 
milliseconds are taken too although it doesn't show them.

Does anyone now how to create a Date with only HH:MM:SS.00000000... or a 
better solution? 


Thanks in advance!

Hi MIsabel,

Unfortunately you cannot synchronize a stimulus computer and an EEG
recorder accurately this way. Most EEG systems have a special feature to
synchronize with external systems. Traditionally this is done by using a so
called TTL signal, which can be generated using a parallel printer port for
example. Such a signal can be generated by EPRime with millisecond
accuracy. But there exists other synchronization methods as well, so it
depends on the EEG recorder what type of synchronization is supported.
Perhaps I could be more specific if you mention the type of EEG device
you're using...

Best,
Paul

Hi Paul, 

Thanks a lot for your answer!

I'm using this EEG recorder ( http://www.neuroelectrics.com/enobio ). It 
has a TCP/IP port opened for send triggers and it seems to be the easiest 
way of communication. 
Here ( http://wiki.neuroelectrics.com/index.php/Interacting_with_NIC ) is 
explained how to interact with NIC using other software, and the choices 
they give are TCP/IP and LSL.
Also, I saw they have an External TTL Input Recorder ( 
http://www.neuroelectrics.com/sites/neuroelectrics.com/files/enobio/NE_TTL_Trigger_Receiver_UserManual.pdf 
) but I don't have it . If there is not solution I guess I would have to 
buy it.

Hope anyone can help me. Thanks!!

If you don't  need accuracy under 100 ms, you could use the TCP/IP
communication protocol, which is also supported by EPrime when using inline
script. However, that would not be good enough for most EEG/ERP
experiments, so in that case you could use the other (LSL) protocol. The
downside of that is that LSL is not supported by eprime, and the only way
to implement it would be to use an external DLL or COM object that is
programmed in a programming language like C++. (Which requires serious
programming skills.) So, when that is not an option, you should probably
buy the TTL input recorder because it is not very difficult to generate the
TTL trigger on computers that have a parallel printer port. (Double check
this on the PC you are going to use for EPrime.) By using the trigger
input, you will loose the option to send unique markers for specific events
or types of stimuli. Perhaps it would be possible to combine the TTL input
recorder and TCP/IP to get the best of both worlds: sufficient accuracy and
coded markers.

Subject: Naming a specific trial in the trial list
Message-ID: <TUE.29.JUL.2014.110653.0700.>

Is there a way to label a specific trial with a name? I would like to 
present a specific trial after a certain number of trials and was wondering 
if there is an inline code where I can refer to the trial 
ie. If TrialCount = 250 Then display TrialList.ID = 7

Something along the lines of that?

Hi Jerry,

There are several way's to do such a thing without using inline script. If
the trial list is ran sequentially, you could simply add a specific trial
procedure by inserting a row into the list at level 250. This specific
trial could have a different name and is configured completely independent
of the other trials. However, if you use some kind of trial order
randomization, things become slightly more complicated. In that case you
would have to put the special trials in a separate list. The two lists with
regular and special trials can then be used as nested lists in a master
trial list. The master trial list can have two levels: the first having
weight=250, nested list=RegularTrialList and proc=RegularTrialProc; the
second having weight=1, nested list=SpecialTrialList and
proc=SpecialTrialProc.

Lots of trial and block orders are possible when using nested lists this
way.

Best
Paul

Subject: Task Events and using ACC as a Source
Message-ID: <WED.30.JUL.2014.130713.0700.>

Hello,

I was wondering if anyone else had managed to work out how to get ACC to 
work as a source for task events and triggering to a BioSemi system? I am 
using E-Prime 2.0.10.353 Pro.

I have managed to make RESP work as a source, however whenever I use ACC 
the programme errors out saying the parameter is not found.

I have tried to correct these issues multiple ways (e.g. putting ACC InLine 
prior to response - this just resulted in ACC not being coded and the 
programme still errored out; specifying data type as various things e.g. 
byte, integer, long - this made no difference, same error message; 
specifying Generate PreRun to TopOfProcedure/BeforeObjectRun - only 
BeforeObjectRun works with RESP, but altering this made no difference to 
the error message displayed using ACC....)

As I am using BrainVision to analyse the data, it would be preferable to 
get ACC to work for triggers rather than RESP (getting ACC to work will 
enable me to drag and drop analysis trees rather than having to alternate 
trees depending on the counterbalanced version of the task used).

Unfortunately, I have not received much help from the E-Prime 
documentation. PST support, while they have been in contact (and continue 
to do so) their suggestions are currently making no difference to my 
ability to use ACC as a task event source. I therefore thought I would ask 
here in case anyone else has overcome this issue!

Any help anyone can offer would be greatly appreciated. 

Thank you in advance for your help with this issue.
Amie

Subject: Does SRBOX/Microphone setup effect RTs?
Message-ID: <THU.31.JUL.2014.075425.0700.>

Hello,

I have a question regarding using a microphone for measuring RT and audio 
input for a battery I am working on.

I am debating on whether using a audio splitter (a y cable) to send the 
signal to the SRBOX and the computer's recording device vs. using two 
microphones. If I choose to use two microphones, this creates extra 
environmental stimuli, would make positioning the microphones and testing 
the setup in the middle of data collection very time consumming (I am using 
non SRBOX tasks and SRBOX tasks that have a set order), this might create 
inconsistencies with data collection (each individual has a slightly 
different positioning, sound doesn't capture, etc), and the whole 
experience might be overwhelming for the participant. On the other hand, 
using the splitter would eliminate this issue, but I am not sure if there 
would result in differences in RT logged by E-Prime (this would be in ms 
and could make or break our outcomes). 

Does setup (using a splitter vs. two microphones) effect reaction time? I 
would be interested to know if anyone has looked into this, had any 
experience using either setup, or measured this.  Feel free to let me know 
or tell me I am overthinking this.

Thanks,

David

Message-ID: <THU.31.JUL.2014.115741.0400.>

David,

I dearly hope that you get simultaneous voice key and sound recording 
to work with a single microphone, and then report back here on how to 
do it.  I never got that to work here, we gave up and used two 
microphones, one for the voice key (SRBox) and one for sound 
recording through the computer's mic input.  Some details ...

In short, when we used any sort of Y splitter to connect one mic to 
both SRBox and cmoputer mic input, we had trouble getting the voice 
key to respond, and the recorded sound contained a high-pitched 
whine.  I worked on this with PST Support, and they could not do much 
better themselves -- in their own tests using a splitter, either the 
voice key did not work, or the audio quality was degraded (e.g., low volume).

In case it helps, the SRBox uses a dynamic microphone (see 
http://en.wikipedia.org/wiki/Microphone ), with a 3.5mm unbalanced TS 
(tip-sleeve) connector.  Computer mic inputs typically use a 
condenser mic, with a 3.5mm TRS (tip-ring-sleeve) connector where the 
computer may supply power to the mic through the ring.  So things get 
complicated already right there.  Beyond that, I suspect that each 
device connected to the microphone presents an additional load, and 
the microphone simply cannot handle the load of two input devices, 
which would account for the loss in volume.

What we need, of course, is a device that presents a low load to the 
microphone, and can drive multiple loads for the next 
stage.  Ordinarily, that device would be a preamp that supplies 
line-level signals to the next stage.  Unfortunately, in our case a 
line-level signal will likely overload our inputs -- the SRBox can 
take only a mic-level signal, and many computer sound devices no 
longer provide a line-level input, they provide mic-level input 
only.  If you can find a device that takes a mic-level input and then 
buffers that to provide output to multiple mic-level inputs, that 
would be great, but I asked around and could not find such a 
device.  One other option might be to use a preamp, as mentioned 
above, and then attentuate the preamp output using something like a 
series resistor to the mic-level inputs.  I have not yet tried this 
myself, so if you get this to work please write back.  (Even if this 
works, it just seems twisted -- I mean, first we would boost the 
signal from the mic, then attenuate the boosted signal back down to 
mic level so that we could feed it into another mic input that then 
boosts it yet again -- sheesh!)

So in sum, splitting a microphone between the SRBox voice key and the 
computer sound card is not as straightforwared as you might think, 
and in the end using two microphones still seems the best solution.

But to answer your question, I cannot think of any reason that using 
a splitter would affect the measured reaction time, the electric 
signal should travel at the same rate with or without a splitter.  Of 
course, that should be tested empirically (and no one should just 
take my work for any of this :) ), but I would be very surprised if 
it made any difference.  But note that, even with a splitter, as a 
result of latencies in sound recording you will almost certainly find 
a discrepancy between RT measured by voice key vs. sound recording, 
see thread at https://groups.google.com/d/topic/e-prime/DcKdgNJKAlM .

Hi David,

I have been using both E-prime v2.0.8.22 and v2.0.10.353 on the same 
machine for some time now.  It works perfectly!  I definitely recommend 
using the method you suggested in the thread.

Thanks again for all of your help!

Subject: Using and Modifying a VAS
Message-ID: <TUE.1.JUL.2014.085812.0700.>

Hello,

First, let me thank Paul Groot for creating and posting his visual analog 
scale.

Second, I am trying to modify it for my purposes. The primary challenge is 
that it was written in E-Prime 1.0, and I use 2.0. When 2.0 opens it, I 
cannot access the script. E-Prime buries the script, at least so that I 
cannot find it and thenceforth modify it.

In my pilot, I have two blocks. The first presents in random order a jpg to 
be rated on the same screen as the VAS. (Easy and done!) The second 
presents again in random order the jpg in a slide prior to the VAS; i.e., 
the VAS will be alone on the screen with the prompt question. Copying and 
pasting Groot's three key objects into another procedure (so that E-Prime 
adds a "1" to the end of their names) results in a crash upon running it, 
given that the script, I deduce, references objects by name. Having the 
same objects in two different procedures, such as in Groot's example file, 
however, means that the second time around, the jpg is shown both before 
the VAS slide and on the VAS slide as well.

Does somebody know a solution... how to access Groot's hidden-by-EPrime 
script so that I can change the objects' names for the second block? how to 
insert an object that will cover the photo in the second run-through, even? 
some other solution?

Thank you!

Humbly,

Chris

P.S. I tried accessing Groot's website since I downloaded the VAS some 
months ago, for I seem to remember the script file being there. However, 
the protections on my server are blocking it, saying it is now blacklisted 
by DNS.

Hi Chris,

I'm not aware of being blacklisted anywhere, but I will attach the EP2 VAS
example script and package to this email. The version-2 script uses an
eprime package to simplify importing the code in your own scripts. You will
need to use the PackageFile editor of EP2 to open/edit the embedded
scripts. I'm not sure if that will be required, because the name of the Vas
slide can be specified as argument in the InitVas package call. (You will
have to edit this after copy-pasting. I think the example script shows 3
different Slide objects) However, feel free to edit the code provided
inside the VAS package.

Best,
Paul

Hi David,

I'm already using the procedure you said. I have a master list as a top 
layer for two procedures Control and WM each having a weight of 30 with 
random selection. Each procedure has a sub list with 30 of trials namely 
Control & WM Trial List. Each sub list has a trial procedure with and 
without condition. The randome

I am supposed to get random trial from this setup, which I believe am 
getting but I am not sure about that. Due to the usage of IFIS paradigm 
design wizard, the trial run does not completes all 60 trails. It only runs 
for random 17 trials and asks for continuing or end the trial. It restarts 
the trial cycle if I continue or ends. I'm not sure how do I cope with this 
situation. Any suggestions would be quite helpful. 

Best Regards,
Dilip

Dilip,

I'm not sure that we're talking about the same thing.  You refer to 
three Lists, a master List with two sub-Lists.  I am talking about 
only one List that has rows for both types of trials, differentiated 
by what Procedure you put in the Procedure column of each row.  Does 
that make any sense?

As for the rest...  You use IFIS, eh?  Sigh.  Don't get me started on 
IFIS, we used that mess years ago and were glad to discard it, we 
just do straight E-Prime now and are happier for it.  So I do not 
care to sink my mind into all the IFIS nuances just now.  But I do 
recall that IFIS puts a few control Lists down in Unreferenced 
E-Objects, and you have to pay close attention to those because some 
of those values will override the control values up in your E-Prime 
design.  (Unless, of course, you have some newer and nicer version of 
IFIS that I do not know about.)  (And if you search the group for 
"IFIS", you may find further statements from me at 
https://groups.google.com/d/topic/e-prime/8e1YmtDQVNY .)

Best,

Hi there,

Has anyone experienced this type of error before? It happens when I try to 
open some files that have previously worked fine. I haven't made any 
changes to the files in the mean time, it's just that now they won't open 
and I get this message. They're pretty simple experiments too so I can't 
think what this refers to.

Thanks in advance,

Adele

Thank you for your help. The network at where I work has a strange

Ok thanks Paul,

I had never seen the use of &H to convert from ascii to hexadecimal. 
that makes things pretty clear.

Subject: Sending non-printable ascii characters via serial port
In-Reply-To: <CAKAdR-sKYK+UwMnHR8p0EU3ZhjB9gNNpS24O-kw_dFDq_aaRtw@mail.gmail.com>
Message-ID: <WED.9.JUL.2014.115904.0700.>

Paul,

So this method would send the binary equivalent of those hex values which 
represent ascii characters.

Do you know if/how Serial.WriteBytes is different from Serial.Write?

I would assume that either way the information is going to be sent in the 
form of bytes through the port. Is the protocol for how e-prime sends bytes 
different for one method vs. the other.
Or is WriteBytes the same as Write except one takes hexadecimal values and 
one the other takes string values then converts them to bytes?

Any wisdom you could pass on would be much appreciated once again.

Cheers,

J

Subject: Converging trials with and without conditions into one Trial
 List...!!!
In-Reply-To: <53b420ff.255d320a.5554.7ff4SMTPIN_ADDED_MISSING@gmr-mx.google.com>
Message-ID: <WED.9.JUL.2014.182438.0700.>

Dear David,

I was suggested by an Engineer to mix these two trial list and converge 
them into one and only one list which is not possible because both the 
tasks have different trial structure and conditions. I had to assign each 
task with one procedure separately as you mentioned below.

Yes unfortunately our collaborator uses quite old version of tools and we 
have to do the same. We have to use IFIS and E-prime 1.1 on Windows XP OS 
to design our experiment.
I'm getting the random trials as desired and can run the complete trial 
list on E.prime 2.0 version but different is the case for IFIS. The 
complete task runs around 10 to 12 minutes and I can run it only 3 to 4 
minutes on IFIS based system. I have just learned that their scanner cannot 
run fMRI longer than 4 minutes continuously due to the larger size of the 
data and takes a 2 minutes break after every 4 minutes of fMRI run. I 
suspect that might be the reason for my problem. I'm trying to resolve this 
issue with their technical team.
The only solution i can foresee is to break the task into small runs.

Thanks for getting back to me on this issue. Any feedback on this will be 
strongly welcomed

Best Regards,
Dilip

Subject: Sending non-printable ascii characters via serial port
In-Reply-To: <36c2a30d-db0a-48b1-8e64-187a18b92292@googlegroups.com>
Message-ID: <THU.10.JUL.2014.102742.0200.>

Well, I'm not sure about the SerialDevice.Write function because that one
is not documented (does it really exist?) But you're right, at the end of
the story all data is exchanged as sequence of bytes; one byte at the time.
(Together with the configured start-, stop and parity bits, but that is
completely transparent to the programmer once the device is open for use.)
So, PST added a few useful wrapper functions to do the conversion to and
from bytes automatically for a few frequently used data types. Those
functions make it possible to send and receive text strings, 2 byte
integers and 4 byte integers, by calling one of the wrapper functions. On
the lower level, this conversion is pretty straightforward because the
internal (in-memory) representation of this data is already a sequence of
bytes. However, things become confusing for most people when ASCII
characters have to be translated to their numerical representation, and
vice versa. Especially when the text contains numbers. But that is
something you already figured out. (I'm just ignoring multi-byte character
sets for the moment, because that's even more challenging.)

A similar thing is true for the way numerical data is represented in
E-Basic. A numerical value can be represented by E-Basic in several ways:
decimal, hexadecimal, ... It's just the textual presentation in the script
that is different; once the value is stored in memory their is no
difference in the byte values. The &Hxx syntax is mainly available for our
convenience; to make life easier when dealing with binary data. In theory
it would have been possible to add support for a binary representation in
E-Basic, but unfortunately that is not available. But no matter what the
textual representation is, at the end it is just another byte in memory.
Regarding this point, you might also have a look at the Asc() and Chr()
functions. These functions will convert characters type to numerical type
(and back), without changing the value in-memory. This allows you to write
Asc("@") instead of &H40 or 64.

Hope this helps to understand the (seemingly) subtle, but important
differences.

Paul

Subject: Minimum trial length before termination response is allowed
Message-ID: <THU.10.JUL.2014.120912.0700.>

Hi all--first time posting here.

My question is, I am running an experiment in which subjects have to type 
1-word answers per trial.  

The time limit of each trial is unlimited as intended.

Subjects are instructed to press "ENTER" after finishing typing; this 
advances to the next trial.

However, I would like to add the following:

   - Is it possible for there to be a minimum trial duration before 
   pressing "ENTER" terminates the trial?
   - OR, is it possible for there to be a minimum number of letters (e.g., 
   3) typed before the trial can be terminated?

We have had subjects press "ENTER" reflexively without typing anything, and 
I was wondering if there was some sort of inline script that could be added 
to prevent this.

Thanks for any suggestions!

Subject: Question about setting up a wav file to repeat throughout
 experiment
Message-ID: <THU.10.JUL.2014.191847.0700.>

Hi all, 

First off thank you for setting up this group - it's been a lot of help 
reading through.

I'm having some trouble figuring out how to make a sound file repeat itself 
every certain amount of seconds in EP1. Basically, I want to set this loop 
to play a beep in the background while other things are going on (stimuli 
being presented on the screen). I would need the sound to repeat itself 
during most of the experiment and was thinking that instead of ending the 
loop during the intermittent times I need it not to play, I would just mute 
the sound output (if possible from E-Prime) during these sections and just 
resume it after the section is completed.

What would you all recommend as the best way of succeeding this? 

Thank you in advance for all the help.

Hello - 

I'm attempting to create an inline statement that inputs a duration value

Subject: inline statement ImageDisplay duration
In-Reply-To: <a61f01dd-d635-4124-86c9-e0f63c21d249@googlegroups.com>
Message-ID: <MON.14.JUL.2014.093950.0200.>

Hi Semeon,

Instead of using an inline, it should be possible (and easier) to define
the duration as attribute at the blocklevel list. (I think that would be
TalkerList in your script).
Just add an attribute to the list (i.e. *RespDuration*) and use this
attribute name as duration value in Response->Duration by using the square
bracket reference method: *[RespDuration]*.
EPrime will then use the duration values defined in the list for each block.

Best,
Paul

Subject: Upload two different images with different contingencies
 (reversal)
Message-ID: <MON.14.JUL.2014.010645.0700.>

Hi everyone,
 
I started a few weeks ago with e-prime and I can run basic experiments but 
I have to make a reversal task to start as soon as possible with my study 
and I am struggling with this task so I will be very grateful if you guys 
can help me with this. Thank you.
The experiment consists in two figures where one of those is correct most 
of the times and receive feedback when selecting it (the feedback, smiley 
face has to appear while the two figures are still on the screen), then 
fixation and another trial with the same figures but in different locations 
(right/left vs left/right). After that the contingencies reversed  after  6 
to 10 choices of the highly rewarded stimulus. Well, this would be the 
first step, but I got stuck uploading each figure and giving them the 
proper contingencies, which the correct figure would result in reward on 
80% of trials while the incorrect one would be rewarded on 20%. Any help is 
more than welcome, thanks in advanced.
 
Best,
Nata

 experiment

Hi,

Did you succeed yet?

I thought this wasn?t possible, actually, thinking that whatever you create the sound object as will be permanent. But, not so; the sounddevice itself (turn on sound device in experiment settings, will create global ?sound? object) can be adjusted. For example, if you have a soundout object (let?s call it soundout1, and make it play windows critical stop or some such, set it to loop, turn on volume control, and delete it/make it unreferenced), this will work:

 

Dim i As Integer

soundout1.Play 

For i = -10000 To 0 Step 100

      sound.Volume = i

      debug.print i

      sleep 100

Next i

sleep 2000

 

It looks better if you use a dual monitor setup and check the debug screen.

Hope that helps.

Best,

Michiel

Subject: Question about setting up a wav file to repeat throughout experiment

 

Hi all, 

First off thank you for setting up this group - it's been a lot of help reading through.

I'm having some trouble figuring out how to make a sound file repeat itself every certain amount of seconds in EP1. Basically, I want to set this loop to play a beep in the background while other things are going on (stimuli being presented on the screen). I would need the sound to repeat itself during most of the experiment and was thinking that instead of ending the loop during the intermittent times I need it not to play, I would just mute the sound output (if possible from E-Prime) during these sections and just resume it after the section is completed.

What would you all recommend as the best way of succeeding this? 

Thank you in advance for all the help.

Subject: Loading one attribute from a list
Message-ID: <MON.14.JUL.2014.084935.0700.>

Hello to everyone,

I know how to load a complete list from a text file. However, I have now a 
difficult problem: I would like to load only ONE attribute from a text 
file. I know I could generate the whole list and load all of it, but it 
would be better for the design of the experiment to generate most of the 
list property from within e-prime and generate one attribute from outside. 
Is this possible?
Thank you very much,
Valerio

Valerio,

Try removing the attribute from your main List, and for each level of 
your main List add a nested List, say, LoadList.  Then load your 
nested LoadList from a text file in the usual way.  For each trial, 
E-Prime will take all the attributes from one row of your main List, 
plus the added attribute from the nested LoadList, which in turn came 
from your external text file.

Hope that helps.

Hello,

I am building an experiment in which answers should be recorderd. It is a

asked to name it. I am having some trouble in recording the answers. I have 
watched some e-prime tutorials and so far what I understood from the videos 
is that I must have a serial response box in order to record the answer and

Please work through all the tutorials in all of the manuals that come

keyboard, record vocal responses to sound files from the microphone, etc.

Subject: Spacebar presses increases after every reward
Message-ID: <THU.17.JUL.2014.112431.0700.>

Hi there,

I apologize in advance for being naive with E-Prime scripting and inline 
scripting.  I want to create an experiment where a participants needs to 
press the spacebar multiple times for a reward. For example, first they 
press two times on the spacebar then get the reward, then they press four 
times then get the reward, then 8 times, and so forth... Since I know I'm 
not reinventing the wheel here, I'm sure someone has looked at this... 
would anyone know if there is a sample out there investigating this? Any 
help would be appreciated! 

Thanks in advance!

Hi Natalia,

I'd need more information from you to be able to advise.

What IS working and what IS NOT working? (e.g. image display; detection of 
mouse click on images,...)

Do you get an error message (what) or does it just not work how you want it 
to work?

Subject: Two images in the same slide, sifferent stimulus
In-Reply-To: <854f078e-8d26-4c19-a07e-f5f8fb7fe7c2@googlegroups.com>
Message-ID: <FRI.18.JUL.2014.093034.0700.>

It sounds like you are trying to build a probabilistic selection experiment 
similar to the one described in a paper by Frank, Seeberger, and O'Reily 
(2004), where ...
 
  1. The participant is instructed to choose which object is "correct".  
  2. The objects (stimuli) are chosen in pairs (AB, CD, EF, ...) and 
displayed at random.  But it seems like you want to have them permanently 
set to one side (?). 
  3. Feedback is given after each trial for each condition. The object is 
"Correct" either 80%, 70%, and 60% of the time and "Incorrect" either 20%, 
30% and 40% of the time.
 
Is this right?  Following John's response, where in your design are you 
having issues?
 
Thanks,
 
David

Hi!
 
Thanks a lot for your help. As an e-prime beginner I'd like to do the task 
step by step even though what I want to achieve as a result is what David 
described in his response. I would like to know how can I put two different 
images in the same slide and give them a different correct response 
depending if it is the right or the left image, How this would look like in 
the list and procedure?. The second part is that I need a feedback for the 
correct and incorrect response but I'd need that this feedback comes up 
while the images are still on the screen. Thank you very much for your help.
 
Cheers,
Natalia

Subject: Presenting a trial at a specific trial number while randomizing
 the rest
Message-ID: <TUE.22.JUL.2014.110659.0700.>

I'm currently working on an experiment where I have 478 random trials and 
then 2 extremely different trials (we'll call Trial A and B). Ideally, I 
would like for the 478 trials to be presented at random and Trial A to be 
presented after 250 random trials and then Trial B to be presented after 
350 random trials. My inline script looks like:

g_nTotalTrial = g_nTotalTrial+1
c.SetAttrib "TrialCount", g_nTotalTrial

If "TrialCount" = "2" Then 
c.SetAttrib "RightCue", "Shape.bmp"
Else 
End If

Trial A and B is supposed to show a different image as the right cue 
(Shape.bmp and Color.bmp respectively). Although I don't get any errors 
running the experiment, Trial A and B are not presented at Trial 250 and 
350. 
**Note that this was just a trial run where I used the trial counter as 2 
and only have Trial A.

Subject: "swirling circle" remains on screen while program is running
Message-ID: <TUE.22.JUL.2014.144752.0700.>

Hi all, 

I'm having an issue with the "swirling circle" remaining on the screen 
throughout the entire time that a program is running. 
By "swirling circle", I refer to the loading icon (replaces the hourglass) 
that is used in Windows 7+.
If it is relevant: 
This is an E-Prime 2 Production Release program.
I have confirmed this to happen on both a Dell and an Asus laptop.
I have confirmed that the mouse device is unchecked in the experiment 
properties. 

Thoughts?  Is this a known bug?   My next strategy would be to fiddle with 
the Windows settings, but if there's something I can fix in E-Prime, I'd 
prefer to do that.

Thanks!

By default, the mouse device is *enabled* (checked), and the 'show cursor'
setting is set to disabled. If you disable the mouse device, EPrime will
leave it as-is and Windows is in control of its shape and visibility.

Message-ID: <WED.23.JUL.2014.123229.0100.>

it's really too general a question for me to answer in a short amount of
time.

If you're a beginner I'd suggest you download and study some of the sample
files on the PST website - see here -
http://www.pstnet.com/support/samples.asp - run them through, see what they
do and then look at the source code to see how it's done.

to get you started, for your varying correct responses, you probably want a
column in your TrialList to store your correct response - eg 'corr_resp'
and then on the properties dialog  for your slide you can put the column
name in the correct response field but enclose it in square brackets e.g.
[corr_resp]

you just need to  populate the triallist table with the appropriate values
to correspond with the images that you'l show. Hopefully you can hard code
these. If not then you can populate the triallist at runtime but that
starts to get tricky for beginners.

Subject: Exact start time
Message-ID: <THU.24.JUL.2014.044422.0700.>

Hi all,

I'm working on an integration of E-Prime 2 Standard edition with an EEG 
signal recorder, and I found a problem with time measurement:

With E-Prime I can see the start time once the experiment is finished in 
the E-Data for example, but it comes with the format "dd/mm/yyyy HH:MM:SS". 
The problem is that I need to know milliseconds of start time too or the 
experiment won't worth it at all.

I looked at Now() and Time$, and both return a Date object with the 
previous format.

Trying to find a solution I though that maybe if I use 
      myDate = DateAdd("s",3,Now()) 
and after it
      While Now()  < myDate
      Wend
I could force the start 3 seconds later, but after test it I realized 
milliseconds are taken too although it doesn't show them.

Does anyone now how to create a Date with only HH:MM:SS.00000000... or a 
better solution? 


Thanks in advance!

Hi MIsabel,

Unfortunately you cannot synchronize a stimulus computer and an EEG
recorder accurately this way. Most EEG systems have a special feature to
synchronize with external systems. Traditionally this is done by using a so
called TTL signal, which can be generated using a parallel printer port for
example. Such a signal can be generated by EPRime with millisecond
accuracy. But there exists other synchronization methods as well, so it
depends on the EEG recorder what type of synchronization is supported.
Perhaps I could be more specific if you mention the type of EEG device
you're using...

Best,
Paul

Hi Paul, 

Thanks a lot for your answer!

I'm using this EEG recorder ( http://www.neuroelectrics.com/enobio ). It 
has a TCP/IP port opened for send triggers and it seems to be the easiest 
way of communication. 
Here ( http://wiki.neuroelectrics.com/index.php/Interacting_with_NIC ) is 
explained how to interact with NIC using other software, and the choices 
they give are TCP/IP and LSL.
Also, I saw they have an External TTL Input Recorder ( 
http://www.neuroelectrics.com/sites/neuroelectrics.com/files/enobio/NE_TTL_Trigger_Receiver_UserManual.pdf 
) but I don't have it . If there is not solution I guess I would have to 
buy it.

Hope anyone can help me. Thanks!!

If you don't  need accuracy under 100 ms, you could use the TCP/IP
communication protocol, which is also supported by EPrime when using inline
script. However, that would not be good enough for most EEG/ERP
experiments, so in that case you could use the other (LSL) protocol. The
downside of that is that LSL is not supported by eprime, and the only way
to implement it would be to use an external DLL or COM object that is
programmed in a programming language like C++. (Which requires serious
programming skills.) So, when that is not an option, you should probably
buy the TTL input recorder because it is not very difficult to generate the
TTL trigger on computers that have a parallel printer port. (Double check
this on the PC you are going to use for EPrime.) By using the trigger
input, you will loose the option to send unique markers for specific events
or types of stimuli. Perhaps it would be possible to combine the TTL input
recorder and TCP/IP to get the best of both worlds: sufficient accuracy and
coded markers.

Subject: Naming a specific trial in the trial list
Message-ID: <TUE.29.JUL.2014.110653.0700.>

Is there a way to label a specific trial with a name? I would like to 
present a specific trial after a certain number of trials and was wondering 
if there is an inline code where I can refer to the trial 
ie. If TrialCount = 250 Then display TrialList.ID = 7

Something along the lines of that?

Hi Jerry,

There are several way's to do such a thing without using inline script. If
the trial list is ran sequentially, you could simply add a specific trial
procedure by inserting a row into the list at level 250. This specific
trial could have a different name and is configured completely independent
of the other trials. However, if you use some kind of trial order
randomization, things become slightly more complicated. In that case you
would have to put the special trials in a separate list. The two lists with
regular and special trials can then be used as nested lists in a master
trial list. The master trial list can have two levels: the first having
weight=250, nested list=RegularTrialList and proc=RegularTrialProc; the
second having weight=1, nested list=SpecialTrialList and
proc=SpecialTrialProc.

Lots of trial and block orders are possible when using nested lists this
way.

Best
Paul

Subject: Task Events and using ACC as a Source
Message-ID: <WED.30.JUL.2014.130713.0700.>

Hello,

I was wondering if anyone else had managed to work out how to get ACC to 
work as a source for task events and triggering to a BioSemi system? I am 
using E-Prime 2.0.10.353 Pro.

I have managed to make RESP work as a source, however whenever I use ACC 
the programme errors out saying the parameter is not found.

I have tried to correct these issues multiple ways (e.g. putting ACC InLine 
prior to response - this just resulted in ACC not being coded and the 
programme still errored out; specifying data type as various things e.g. 
byte, integer, long - this made no difference, same error message; 
specifying Generate PreRun to TopOfProcedure/BeforeObjectRun - only 
BeforeObjectRun works with RESP, but altering this made no difference to 
the error message displayed using ACC....)

As I am using BrainVision to analyse the data, it would be preferable to 
get ACC to work for triggers rather than RESP (getting ACC to work will 
enable me to drag and drop analysis trees rather than having to alternate 
trees depending on the counterbalanced version of the task used).

Unfortunately, I have not received much help from the E-Prime 
documentation. PST support, while they have been in contact (and continue 
to do so) their suggestions are currently making no difference to my 
ability to use ACC as a task event source. I therefore thought I would ask 
here in case anyone else has overcome this issue!

Any help anyone can offer would be greatly appreciated. 

Thank you in advance for your help with this issue.
Amie

Subject: Does SRBOX/Microphone setup effect RTs?
Message-ID: <THU.31.JUL.2014.075425.0700.>

Hello,

I have a question regarding using a microphone for measuring RT and audio 
input for a battery I am working on.

I am debating on whether using a audio splitter (a y cable) to send the 
signal to the SRBOX and the computer's recording device vs. using two 
microphones. If I choose to use two microphones, this creates extra 
environmental stimuli, would make positioning the microphones and testing 
the setup in the middle of data collection very time consumming (I am using 
non SRBOX tasks and SRBOX tasks that have a set order), this might create 
inconsistencies with data collection (each individual has a slightly 
different positioning, sound doesn't capture, etc), and the whole 
experience might be overwhelming for the participant. On the other hand, 
using the splitter would eliminate this issue, but I am not sure if there 
would result in differences in RT logged by E-Prime (this would be in ms 
and could make or break our outcomes). 

Does setup (using a splitter vs. two microphones) effect reaction time? I 
would be interested to know if anyone has looked into this, had any 
experience using either setup, or measured this.  Feel free to let me know 
or tell me I am overthinking this.

Thanks,

David

Message-ID: <THU.31.JUL.2014.115741.0400.>

David,

I dearly hope that you get simultaneous voice key and sound recording 
to work with a single microphone, and then report back here on how to 
do it.  I never got that to work here, we gave up and used two 
microphones, one for the voice key (SRBox) and one for sound 
recording through the computer's mic input.  Some details ...

In short, when we used any sort of Y splitter to connect one mic to 
both SRBox and cmoputer mic input, we had trouble getting the voice 
key to respond, and the recorded sound contained a high-pitched 
whine.  I worked on this with PST Support, and they could not do much 
better themselves -- in their own tests using a splitter, either the 
voice key did not work, or the audio quality was degraded (e.g., low volume).

In case it helps, the SRBox uses a dynamic microphone (see 
http://en.wikipedia.org/wiki/Microphone ), with a 3.5mm unbalanced TS 
(tip-sleeve) connector.  Computer mic inputs typically use a 
condenser mic, with a 3.5mm TRS (tip-ring-sleeve) connector where the 
computer may supply power to the mic through the ring.  So things get 
complicated already right there.  Beyond that, I suspect that each 
device connected to the microphone presents an additional load, and 
the microphone simply cannot handle the load of two input devices, 
which would account for the loss in volume.

What we need, of course, is a device that presents a low load to the 
microphone, and can drive multiple loads for the next 
stage.  Ordinarily, that device would be a preamp that supplies 
line-level signals to the next stage.  Unfortunately, in our case a 
line-level signal will likely overload our inputs -- the SRBox can 
take only a mic-level signal, and many computer sound devices no 
longer provide a line-level input, they provide mic-level input 
only.  If you can find a device that takes a mic-level input and then 
buffers that to provide output to multiple mic-level inputs, that 
would be great, but I asked around and could not find such a 
device.  One other option might be to use a preamp, as mentioned 
above, and then attentuate the preamp output using something like a 
series resistor to the mic-level inputs.  I have not yet tried this 
myself, so if you get this to work please write back.  (Even if this 
works, it just seems twisted -- I mean, first we would boost the 
signal from the mic, then attenuate the boosted signal back down to 
mic level so that we could feed it into another mic input that then 
boosts it yet again -- sheesh!)

So in sum, splitting a microphone between the SRBox voice key and the 
computer sound card is not as straightforwared as you might think, 
and in the end using two microphones still seems the best solution.

But to answer your question, I cannot think of any reason that using 
a splitter would affect the measured reaction time, the electric 
signal should travel at the same rate with or without a splitter.  Of 
course, that should be tested empirically (and no one should just 
take my work for any of this :) ), but I would be very surprised if 
it made any difference.  But note that, even with a splitter, as a 
result of latencies in sound recording you will almost certainly find 
a discrepancy between RT measured by voice key vs. sound recording, 
see thread at https://groups.google.com/d/topic/e-prime/DcKdgNJKAlM .

Hi David,

I have been using both E-prime v2.0.8.22 and v2.0.10.353 on the same

using the method you suggested in the thread.

Thanks again for all of your help!
