**What are you trying to achieve?

Hello. I am building a langage experiment where I show participants (children) movie files with sound and they have to respond with key resp (2 options left or right) which sound did they hear. The learning of the correspondance beetween sound and image is dependant of the feedback. For feedback :
if the answer is correct : I show them image of success feedback
if the answer is incorrect : I show them image of feedback indicating the right answer + showing again the stimulus.

What did you try to make it work?:

I added a code component to my feedback routine. (I tried different formulations but it is not working).

the last one I am trying is the following :

if key_respessai_scpt1_loop1.keys == 1:
img_feedback = ‘feedback_correct.png’

elif key_respessai_scpt1_loop1.corr == 0 and key_respessai_scpt1_loop1.keys == ‘right’:
vid_feedback = ‘Vid_abba.mp4’
img_feedback = ‘feedback_incorrect.png’

elif key_respessai_scpt1_loop1.corr == 0 and key_respessai_scpt1_loop1.keys == ‘left’:
vid_feedback = ‘Vid_aba.mp4’
img_feedback =‘feedback_incorrect.png’

I don’t know if my method is the right one or should I try something else.

Thank you for your time if you are reading me !

What specifically went wrong when you tried that?:

Experiment ended.

Found a solution ! I had to split into 2 routines the feedback : one fore img_feedback and the other for vid_feedback.
