[solved] show sketchpad if keyboard response is not made during previous
I am trying to set up an experiment so that a screen is shown with stimuli for 500ms and if no response is made, another screen with just a fixation dot is shown until they make a response. Currently, if a response is made during the stimuli, the fixation dot is shown requiring the subject to respond a second time. So, the sequence is: stimuli (500ms, set_response_period 'yes'), fixation (0ms, set_response_period 'yes'), keyboard_response (infinite)
Is there a way to specify that if a subject makes a response during the response period, the fixation sketchpad is skipped? Maybe by specifying run if [response]=none? (I tried this but it seems to then not move forward after 500ms for the stimuli).
I have looked through some older posts on this issue and it seems a bit complicated in those cases, however this seems fairly straight forward.
Thanks so much.
