Branched Experiments in PsychoPy

Make an experiment that can take one of several routes depending on how your participants respond.

Overview

Make a consent routine, a trials routine and an end routine.
In the consent routine add a keyboard component that allows either the Y or N key to be pressed.
Add a code component to your consent routine.
In the code component use this in the End Routine tab:

if key_resp.keys == 'Y':
    trialLoopReps = 1
elif key_resp.keys == 'N':
    trialLoopReps = 0

Add a loop around the trials routine (and trials loop) and set nReps to trialLoopReps. if the participant does not consent, this part of the experiment will be skipped!
