Response Modality Modulates PRP Interference, Even When Task 1 is a No-Go Trial

Van Selst, M. & Johnston, J.C.

In a Psychological Refractory Period paradigm, where the first task requires one of several possible responses on some trials (the go trials), but no response on other (no-go) trials, response modality modulates the amount of interference on Task 2 processing. This is true even when Task 1 is a no-go trial. Differences in the cost of switching response sets between processing for Task 1 and Task 2 may provide an account of this surprising phenomenon.
