Thanks again Michael - I’m being too hasty and not testing this stuff!
#beginRoutine Tab
thisResp = [] #make an empty list
#every Frame
keys = event.getKeys()
if keys: # if at least one key exists in the list,
if 'escape' in keys: # now need to check for the quit key ourselves
core.quit()
else: #add this frame keys to response list
thisResp.append(keys)
if len(thisResp) == 2:
thisExp.addData('response',''.join(thisResp))
thisExp.addData('RT',t)
contineRoutine = False #end routine.
