Stroop Process Dissociations: Reply to Hillstrom and Logan (1997)

The Stroop counter model, which shares the assumptions of the application of process dissociation to the Stroop task presented by D. S. Lindsay and L. L. Jacoby (1994) , is described in order to demonstrate the viability of these assumptions in quantitative models of the Stroop phenomenon. An experiment is presented to show converging evidence from applications of the process-dissociation procedure and the Stroop counter model. A demonstration of the Stroop counter model's ability to simulate both accuracy and response latency in the Stroop task is provided in the context of this experiment. Descriptions of the processing architecture in both the process-dissociation procedure and the Stroop counter model are provided, and issues of independence are discussed.
