Hi everybody
I am looking for advice concerning a reaction time task.
the idea is that the participants see a polygon on the screen. in a first round, they should react to the polygon by pressing the space bar. in a second round, they should indicate whether the polygon appeared on the right or on the left side by pressing the corresponding arrows or alternatively L and R on the keyboard. how can this be stored in the builder as a response alternative? how would an excel file (condition file) look like?
thank you very much for all hints!
