I’m attempting to provide feedback to trial items on a Stroop experiment.
I followed the directions on PsychoPy’s website, typing into the Begin Routine tab of the Code component:
if not key_resp.keys : msg="Failed to respond" elif resp.corr:#stored on last run routine msg="Correct! RT=%.3f" %(resp.rt) else: msg="Oops! That was wrong"
When I tested it out, I got the following error message:
if not key_resp.keys :
NameError: name ‘key_resp’ is not defined
Where can I define key_resp?
