I am trying to create an experiment in which:
- a fixation cross appears
- subjects press a key and hold it down
- after a jittered window of time, the fixation cross disappears and the stimuli for the trial appear
Ultimately, I want the stimuli to disappear when the key is released. Currently, I cannot figure out how to make the stimuli disappear upon key release. Any help would be greatly appreciated. I am using iohub and am happy to receive help using the coder or the builder view.
