Change blindness experiment measuring RT

Ok - that makes sense. Try:

#Start of experiment
tStart = False

#Beginning of Routine
if tStart == False: #ensure that timer only starts on first trial
   timer = core.Clock() #start timer
   tStart = True

#Every Frame
if len(key_resp_2.keys) > 0:
   loop1.addData('noticedTime', timer.getTime()) #Add data to csv file
   loop1.finished = True
   tStart = False #Incase you want to do more than one trial

Best wishes,
