How to set the number of congruent and incongruent trials in a Stroop task?

Tylhi — Wed, 07 Oct 2020 14:56:19 GMT

Hi,

I just created a Stroop task based on the following script "strooptask_withvoicerecognition" found on your library.
In this task the number of congruent and incongruent trials is random, but I would like to set this number to a ratio of 50% of congruent and 50% of incongruent. I don't know how I can define the total number of congruent and incongruent trial. May I have to do something with "values.congruence" ?
Can you help me ?

If you need my script, I can send you it.

Thanks in advance,
Best,
Margaux

Hi,

I'm facing a new problem with the same task. When I try to fix the trial duration and the stimulus time, the task don't continue to record voice since the second trial.
I'm would like to display for 1000ms the word, have a response window of 1700ms (starting at the same time than the word) and that the trial lasts 2500 ms in totality. I didn't succed, every time I try something, the task stop to record voice.
Can you help me ?

Hi,

There is a task. I also add a file needed on, but I can't add the other one, an audio file that I use to report an incorrect response (beep). May I can send you this one by email.

your trials ought to be set up like this

<trial yellow>
/ ontrialbegin = [values.color = "jaune"]
/ stimulustimes = [0=jaune; 1000=screen]
/ beginresponsetime = 0
/ posttrialpause = 800
/ trialduration = 2500
/ responseinterrupt = frames
/ validresponse = ("jaune" "vert" "bleu" "rouge")
/ correctresponse = ("jaune")
/ ontrialend = [
    if (text.jaune.currentitemnumber == 5) {
        values.count_congruent += 1;
        values.congruence = 1;
    } else {
        values.count_incongruent += 1;
        values.congruence = 2;
    };
    if (text.jaune.currentitemnumber == 5 && trial.yellow.correct) {
        values.countcorrect_congruent += 1;
        values.sumrt_congruent += trial.yellow.latency;
    } else if (text.jaune.currentitemnumber != 5 && trial.yellow.correct) {
        values.countcorrect_incongruent += 1;
        values.sumrt_incongruent += trial.yellow.latency;
    };
]
</trial>

Hi,

I have another question for a task really similar to the one you helped me. If we said that I use the same script, how can I code in order to only have incongruent trial ?
I tried to change the list as follow :

<list colornames_red>
/ items = (vert, bleu, jaune)
/ replace = false
</list>

<list colornames_green>
/ items = (rouge, bleu, jaune)
/ replace = false
</list>

<list colornames_blue>
/ items = (rouge, vert, jaune)
/ replace = false
</list>

<list colornames_yellow>
/ items = (rouge, vert, bleu)
/ replace = false
</list>

* red = rouge; blue = bleu ; green = vert ; yellow = jaune
But the task still diplay congruent trial. Can you help me with it ?

Thanks in advance,
Margaux
