The effect of first response complexity on the psychological refractory period: A reanalysis.

The effect of first signal complexity on the delay of the second response within the paradigm of PRP has been the subject of several recent papers. The results show that, for the same interstimulus interval, the more complex the first reaction, the more the second response is delayed. This paper reports a reanalysis of the data presented by these investigators in terms of comparable response-stimulus intervals. The implications for theories of limited attention are discussed.
