Group: Forum Members Posts: 39, Visits: 183	Thanks. Now the question is how to record in a data file many responses from a single trial. For example, during one trial participant presses at the beginning the button '1' and holds it for a short period, than s/he releases button '1' and presses the button '2' and again holds it for a while. So in the data file I would need information about what button was pressed or released and when. Is it possible to get something like that?
