Hi! I’m working on adding a part to an experiment and I’m struggling.
The experiment involves a participant seeing a picture, then describing a memory associated with that picture (each picture will have about 2 minutes total). We’re trying to add a portion to the routine (code or builder) that allows us (researchers) to click a key and show “Anything else?” for five seconds at any point of the experiment (without adding time, and only for optional use if the participant stops talking during the 2 minutes).
I’ve been trying to mix and match code based on other posts but no luck (I also don’t have much experience in code, so would appreciate the help!)
if you have a text component in your routine (that says “Anything Else”) I would set it’s opacity to a variable $currentOpacity and set to set every frame. Then add a keyboard component that allows the key your researcher will press for the prompt to appear. Then ad a code component . In the Begin Routine tab use:
currentOpacity = 0
keys_counted = 0
startTime = 0
in the Each Frame tab add:
if key_resp.keys:
if len(key_resp.keys) > keys_counted: # a new has been pressed
keys_counted += 1 # count this key
startTime = t # note the start time of the prompt onset
currentOpacity = 1
if currentOpacity == 1 and t > startTime + 5:
currentOpacity = 0
Thank you so much! I tried that out, and it worked sometimes but not always (I think it only worked if I clicked m (the key I’m using) right when the prompt started but not if it’s halfway through. Just to provide additional information, we show the picture for 5 seconds then a plus sign in the center of screen for 116 seconds for a total of 121 for the whole routine. I changed t to 5 for the code and have the key and text components set for 5s start time and duration 116 s. Also, if possible, I would appreciate if you could help with how to change position of the Anywhere else to be slightly under the center!
. In the Begin Routine tab use:
