+x+xHello! I am interested in running 2 different versions of the Color Word Stroop with Keyboard Responding (English); one version with all congruent presentations, one version with 75% incongruent presentations/25% congruent presentations. I would also like to remove the control trials (color blocks) from both versions and increase the trial presentation amount from 84 to 256 trials. I have tried editing the script, however I receive errors when trying to run the test. Any guidance on this issue? Thanks! What edits did you make and what are the specific errors, please? To make a few general points. (1) To not run the control trials, remove them from the <block>'s /trials attribute. <block stroop>
/ onblockbegin = [
list.latencies.reset();
list.latencies_congruent.reset();
list.latencies_control.reset();
list.latencies_incongruent.reset();
list.responses.reset();
list.responses_congruent.reset();
list.responses_control.reset();
list.responses_incongruent.reset();
]
/ trials = [
1=getReady;
2-85 =noreplace(redcongruent, redincongruent, redcontrol, greencongruent, greenincongruent, greencontrol, bluecongruent, blueincongruent,
bluecontrol, blackcongruent, blackincongruent, blackcontrol);
]
</block>
(2) To increase the amount of trials from 84 to 256, change 2-85 in the /trials attribute to 2-257. / trials = [
1=getReady;
2-257=noreplace(redcongruent, redincongruent, greencongruent, greenincongruent, bluecongruent, blueincongruent, blackcongruent, blackincongruent);
]
(3a) For the version running only congruent trials, simply remove all incongruent trials. / trials = [
1=getReady;
2-257=noreplace(redcongruent, greencongruent, bluecongruent, blackcongruent);
]
(3b) For the version with a 3:1 incongruent to congruent ratio, adjust the ratio of the trials in the noreplace pool accordingly: / trials = [
1=getReady;
2-257=noreplace(redcongruent, redincongruent, redincongruent, redincongruent,
greencongruent, greenincongruent, greenincongruent, greenincongruent,
bluecongruent, blueincongruent, blueincongruent, blueincongruent,
blackcongruent, blackincongruent, blackincongruent, blackincongruent);
]
That's pretty much all there is to it.
