code to collect kepress and log data

Jarrodhollis · June 2021

Hi there I am trying to write some code to creare a random dot experiment.

I have managed to get the basic screen display to work using a python script and I have also managed to inplement variables for Coherence and Direction.

I am having two problems, which i cant seem to solve:

Firstly, the RT time of the keypress is logged but the name of the key that was pressed is not.

Secondly, I am able to run this in a window, but when I try to run in full screen I just get a blank screen.

Please can you help

Hi @Jarrod @Jarrodhollis ,

It looks like you've copy-pasted a complete PsychoPy script into an inline_script item. However, that's not (exactly) the way to go, because the script currently does several things that you don't want it to do, such as initializing another window and collecting a key press.

Here's what I would do instead: use an inline_script to only render the random-dot stimulus. Use this script together with a keyboard_response inside a coroutines item so that you can collect a key press while presenting that stimulus. You can read more about that here:

Good luck!
