A visual forced-choice task with audio stimuli

[Yun_Shen]

I’m a PsychoPy beginner.
I want to create a visual forced-choice task with audio stimuli.
After the participants hear the audio stimuli, they are required to choose one images from 2 by pressing keyboards. Please see the screenshot for demonstration.

My questions are:
(1) How to bind two image choices in a pair in a spreadsheet and make them appear next to each other on the screen? (that is to say, the images are not paired by random)
(2) Similarly, how to bind the audio stimuli to the
image choices? (the audio stimuli are also not random, they should go with the particular image pairs)
(3) How to randomize trial order?

You can just put the two images and the audio stimuli on the same row in the .csv file, and they are bound together by default.

When you load the .csv file in the loop, in the loop type, choose “random”. The the trial order is randomized.
