ABSTRACT
This chapter considers a research question involving memory processes in patients with Dissociative Identity Disorder (DID). DID patients often report inter-identity amnesia, that is, impaired memory for events experienced by personalities. It conducts three separate Bayesian analyses of the same data, considering the memory performance of the DID patients from both parameter estimation and model selection perspectives. Using the inferred raw data the chapter undertakes three analyses that examined, from different perspectives, how the DID Patients relate to the Amnesiacs and Malingerers. The first analysis provides the posterior distribution of the key difference in group means, second analysis provides the posterior distribution of the rate with which DID patients are assigned to either the Amnesiacs or the Malingerers and third analysis provides the Bayes factors for four possible clusterings of the groups. In combination the three analyses mount a strong argument that the research question cannot be clearly answered with the current data set.
