Multiple Responses

KerAnn

My experiment requires me to collect multiple of the same responses within a single trial, categorize these responses by time, and add them over trials. Specifically, the participant would have to hit the spacebar (or any key for that matter) when they believe it is the correct time to respond to an item. Is there a way to collect & count these responses if they are of the same key and in the same trial?

HI,

I am not sure I exactly understand what you are trying to achieve, but that should be possible. Certainly it will be possible with Python scripting. If you could explain again what the exact behaviour is you want (number of responses, type of responses, etc.), I could also tell whether it would work with the items.

The task that I am trying to create is one with a single moving stimuli that travels across the screen and a participant is tasked with responding when they believe the stimuli is in the middle of the screen. This commonly results in multiple of the same responses (i.e., the participant hits the spacebar 4 times in a trial). I am aiming to collect these responses within a single trial, separate them by accuracy (hit the stimulus/missed the stimulus). Ultimately I want to provide feedback to the participant about their total "score" over multiple trials so I am also aiming to track their total hits and misses. If you need any other specific information please let me know. I am attempting to solve this using the python scripting but have been unsuccessful thus far

Hi,

Attached an experiment that implements a procedure to repeatedly poll mouse responses (keyboard works virtually the same). I didn't implement the stimulus presentation. This would have to be integrated in the response polling. Basically, all this procedure does is adding responses to a list. How you process that list later, is up to you.

Does this help? If not let me know!
