I'm relatively new to Inquisit, so pardon me if this is a naive question. I am programming a script for an EEG study where participants will have to listen to audio files, which all vary in their length because the sentences are unique on each trial. We will be recording EEG and motor movement contaminates the signal, so we want to keep responses to only a subset of the trials. However, what we have found so far is that there doesn't seem to be a way to code for the trial to end after the audio file finishes without including a specified timeout or a valid response.
Here's an example of what our trial code looks like, but with a spacebar response, as we can't get it to work without a response.
/ frames = [1=fixation, french_unassociated2, trigger_fr_unas]
/ validresponse = (" ")
/ posttrialpause = 1000
I'd like to avoid having to create individual trials for each stimulus, so if you have a better solution, I would appreciate it.
