Analyzing estimates of automatic and conscious retrieval in between- and within-subjects designs.
The process dissociation procedure (PDP) was developed as a means of quantifying the contributions of conscious and automatic retrieval to memory performance. Although the required inclusion and exclusion conditions are manipulated within subjects in most experiments, several researchers have expressed concerns that the instructions may be particularly difficult to follow under these conditions. Thus, manipulating instructions between subjects may have some advantages, although some aspects of the statistical analysis of conscious and automatic estimates are not routine in such a design. We describe a procedure for this analysis and present some initial data to illustrate its application to PDP. We also comment on other issues related to the calculation of estimates of automatic and conscious retrieval in between- and within-subjects designs.
