I’m a Psychology student and I’ve been trying to design an experiment for a project, however I got blocked at the time I had to use codes for improving some details. (By the way, as I lack of any experience in this field, my question might be sort of genuine).
The experiment routine is the following:
Fixation (400 ms duration) > Stimulus Display (600 ms duration as maximum) > Blank Background (its duration will get max. to 3600ms counting from moment 0 in the timeline)
The response might occur from 250 ms after the Stimulus is displayed to the moment the experiment ends at 3600 ms. Depending when the response occur we will face two conditions:
A) Response 250 - 1600 ms from the Stimulus Display --> A Blank Background will be shown with a duration of 1000 ms itself. After that, Trial 2 would begin with fixation.
B) Response over 1600ms from the Stimulus Display --> Trial 2 would begin with fixation.
So, here it’s the problem, I don’t know how to code in order to set the two previous conditions
