Process dissociation, cognitive architecture, and response time: comments on Lindsay and Jacoby (1994)
Process dissociation is based on 2 assumptions about the processes being dissociated: invariance of the processes across situations, and stochastic independence of the processes. In a recent application of process dissociation to the Stroop task (D. S. Lindsay & L. L. Jacoby, 1994), both of those assumptions were violated. It is argued that these violations were due to (a) an oversimplification of the processing architecture that ignores common stages such as guessing and response selection, (b) an assumption that the more automatic process (word reading) dominates over the intended process (color naming) in determining responses, and (c) an assumption that switching from the more common speeded response instruction (measuring speed) to a deadline response instruction (measuring accuracy) does not change processing. General implications for applying process dissociation to dynamic tasks are discussed.
