Sampling eye data while waiting for response
I have an (EEG) experiment where I would like to check whether pp hold fixation using an Eyelink 1000 while they perform visual search. I have written some code that worked in the past. However, in this experiment I am using the keyboard response item and now I am not really sure how to implement my code. Basically, I need to continuously sample x, y coordinates while waiting for the response. If I understand the keyboard item correct, however, the experiment basically freezes untill a response is given or response time is running out.
How could I get around this?
