The Process-Dissociation Procedure (PDP) is one of the experimental methods used to prove that two memory processes, consciously controlled and automatic recollection processes, are working in parallel, and is also a method to estimate relative strengths of each processes. In this article, theoretical basis of the PDP were reviewed with several successful results in human memory experiments. After years of criticism and debates, the PDP has been evolved and its necessary conditions of applicability are now explicitly available. Focusing on the potential power of the PDP, which exists in its assumption of parallel mental processes, the method could be used in wide, different psychological research areas other than human memory. The applicability of the PDP as new research methods was also reviewed with some case examples.
