Hi,
I have one question about EV setting. In experimental trials, subjects received 2 brief tactile stimuli (each 10 ms) with an interstimulus interval of 50 ms. After 5 s, when they saw a response cue, they have to indicate if the the stimulation consists of 1 or 2 stimuli. We are interested in (a) stimulus-related activity, and (b) decision-related activity during the 5-s interval. For the EV (a), we set the duration as 0 s (should we use 0.05 s?), whereas for (b) we set the duration as 5 s. I wonder if this is appropriate and have no idea if both HDRs overlap partially. Hope some experts can give me some clarification. Thanks.
Mike
