Random EEG triggers

Francis&m — Thu, 13 Apr 2023 17:59:23 GMT

Hi,
I'm creating an experiment where participants are watching one video at a time and after each video they answer a question by pressing a key.
I'm recording EEG data during the task.
My trial order looks like this: fixation, video, question + answer, fixation, video, etc.

Since I need to show different videos in a specific order, I created a unique trial where the video is selected based on my order and also I created a conditional statement to send a specific trigger depending on the condition to which each video belongs.

The script is working fine except for the triggers in the video trials, as they go crazy after a while (not from the beginning) by sending triggers I didn't define and also sending multiple triggers for a single video. Fixation triggers also create similar problems.

Triggers are working fine for the question trial ("taskMF") and the key response.
I have no clue of what is going wrong, can someone please help me?
Sorry for my bad coding style.

Thank you very much,
Francesca

RE: Random EEG triggers

Dave — Thu, 13 Apr 2023 17:59:23 GMT

[b]Francis&m - 4/13/2023[/b]
Hi,
I'm creating an experiment where participants are watching one video at a time and after each video they answer a question by pressing a key.
I'm recording EEG data during the task.
My trial order looks like this: fixation, video, question + answer, fixation, video, etc.

Since I need to show different videos in a specific order, I created a unique trial where the video is selected based on my order and also I created a conditional statement to send a specific trigger depending on the condition to which each video belongs.

The script is working fine except for the triggers in the video trials, as they go crazy after a while (not from the beginning) by sending triggers I didn't define and also sending multiple triggers for a single video. Fixation triggers also create similar problems.

Triggers are working fine for the question trial ("taskMF") and the key response.
I have no clue of what is going wrong, can someone please help me?
Sorry for my bad coding style.

Thank you very much,
Francesca

When you insert stimuli into a trial's stimulus presentation sequence those insertions persist across instances of this trial, unless you explicitly reset that trial's stimulus presentation sequence to its original state by calling the resetstimulusframes() function.

https://www.millisecond.com/support/docs/current/html/language/functions/resetstimulusframes.htm

That is, if you insert stimulus A in the trial's 1st instance, and stimulus B in the trial's second instance, then the 2nd instance will display both stimulus A and B.

That is what is happening here with your triggers. Your trial isn't just presenting a single specific trigger, it's presenting multiple overlapping ones.

Observe what happens in the below examples with visual stimuli. The same is true for any other type of stimulus, including <port>.

[code]<block myblock>
/ trials = [1-3 = mytrial]
</block>

<trial mytrial>
/ ontrialbegin = [
    trial.mytrial.insertstimulusframe(list.stimuli.nextvalue, 1);
]
/ stimulusframes = [1=clearscreen]

/ validresponse = (57)
</trial>

<text a>
/ items = ("A")
/ position = (50%, 45%)
</text>

<text b>
/ items = ("B")
/ position = (50%, 50%)
</text>

<text c>
/ items = ("C")
/ position = (50%, 55%)
</text>

<list stimuli>
/ items = (text.a, text.b, text.c)
/ selectionmode = sequence
</list>[/code]

vs.

[code]<block myblock>
/ trials = [1-3 = mytrial]
</block>

<trial mytrial>
/ ontrialbegin = [
    trial.mytrial.resetstimulusframes();
    trial.mytrial.insertstimulusframe(list.stimuli.nextvalue, 1);
