Unable to code a forced-choice option
Hi, I would like to code a forced-choice option whereby subject can only proceed to the next trial upon answering the question from the current trial within 3 seconds, upon 3 seconds there will be a screen preview prompting subject to make a choice so that they can carry on with the experiment.
This is the part where I am unable to make the "prompting screen" pop up after 3 seconds and move on to next screen only if responses are made. I tried changing the guess_prompt to [response_time] but the guess prompt screen does not appear. If I changed it to "always" then it appears in every trial which isn't what I want.
Please guide me on the necessary coding needed to run this program. Thank you!!
