if response.keys: # if the list is not empty
    border.opacity = 1 # needs to be reset on each trial
    if response.keys[0] == ('f'):
        border.pos = [-0.3, 0]
    elif response.keys[0] == ('j'):

  • Don’t use ‘break’. Remember this code is embedded amongst lots of other code, so you don’t necessarily know what that will do. Instead, use the recognised way to end a routine: continueRoutine = False.
  • The NoneType error worries me a bit: hopefully the new first line in the code above might help, otherwise there is some other issue going on.
