Hello,
I've downloaded and modified the Stroop script that is provided by your website for an experiment. I've noticed an important problem in the database and would like to know if there is a simple way to fix it.
As a reminder, a Stroop task randomly displays congruent and incongruent trials. You can see in the screenshot below that, instead of reporting a blank in the congruent column when displaying an incongruent trial, it copies the value of the previous congruent column. The highlighted cases are the problematic ones.
Copying the previous value is actually creating false means (as it duplicates values) and hence, completely messes up the data. I'd like it to report a blank in the congruent column when displaying an incongruent trail (as shown below). Is there a way to do this ??
Thanks for your help.
Regards, Vincent.
