OS:MacOS - latest
PsychoPy version: V2022.2.5, latest, 3.1.2, 2023 (my “stable” is on V2022.2.5, but I’ve tried the others based on other people’s forum posts)
Standard Standalone? (y/n) If not then what?: y
What are you trying to achieve?:
Participants should see an ITI fixation cross on the screen for 1-1.5 seconds, then be presented with the stimuli (text - numbers 1-9) for 3 seconds, they are to press P/Q to indicate correct/incorrect match (2-back paradigm).
What is happening however, is that the reaction time recorded for the P/Q response can be negative (i.e., recorded during the ITI presentation), and the 3 second keyboard recording window is actually 3 minus the ITI time, even though the stimuli number is still on the screen for a full 3 seconds.
What did you try to make it work?:
Tried $iti.status==FINISHED (doesn’t work, incorrect media, simply throws an error as our ITI is a code snippet and the cross that is paired with it is text stimuli)
Tried starting the keyboard response to be when the text stimuli is presented and all other possible duration/time/condition combinations, none of them work. They all continue with negative times, no keyboard recording at all, or positive numbers - but these numbers are recorded during the ITI.
