Abstract

Retrieval-enhanced suggestibility (RES) refers to the finding that immediately recalling the details of a witnessed event can increase susceptibility to later misinformation. This finding is particularly surprising considering decades of research on the testing effect, which shows that retrieval practice enhances memory and protects learners against subsequent memory intrusions. Although many researchers have found RES effects in their experiments, many investigations into RES have yielded mixed or null results. Thus, retrieval-enhanced suggestibility is an intriguing finding deserving of empirical review through meta-analysis. The objectives of this dissertation are to: (a) test retrieval-enhanced suggestibility through experimentation in two new contexts; (b) identify the overall size of the retrieval-enhanced suggestibility effect; and (c) identify the methodological factors that moderate the size of the effect.
