OS (Win10) (also on Win 7):
PsychoPy version** (1.90.3):
I’m new to psychopy and am creating a simple experiment. It’s a selective attention task that shows one of three stimuli (T, X, or C) in a fixed order. The start time of each stimuli is defined in my conditions file as $stimtime, a column of random numbers between 0.55 and 2.25.
The objective is to push the down key when the X stimulus appears.
Here’s how I initially put the response key. I tried all the different options in ‘Store’.
When I run my experiment, after the instructions, the first stimulus shows appears, but nothing after that. The screen just remains grey and doesn’t present the rest of my stimuli.
I went into the response, and entered a duration of 0.7 seconds, and that fixed the problem. All of my stimuli appeared in order as they should. But, then a problem with the data came about. For every response, it would show the response as one stimulus after than the response actually occurred. Giving an incorrect response both for the X and the following T. I did it multiple times and had other people do it to make sure I wasn’t just responding slowly.
Also, if I remove the response key entirely, the task runs fine (besides not being able to respond) and all the stimuli appear.
I’m lost at this point so any help would be greatly appreciate!
