Encoding and referent event influence on retrospective memory

Previous work from our lab has shown that event structure can influence memory performance. Our work in prospective memory has shown that, consistent with an event model view, performance is better when multiple encoding events refer to a common retrieval event. The aim of this study was to assess the generality of this influence of event model structure on memory by using two retrospective memory tasks. This was done using lists of sentences (Experiment 1) and narrative texts (Experiment 2). The results of these retrospective memory tasks replicated that of the prospective memory task and are most consistent with an event cognition account. These results also suggest that encoding and referent event structures may affect some levels of representation (e.g., the surface form) more than others (e.g., the textbase and event model). Overall, we demonstrate that event structure has principled influences on memory apart from the nature of the materials or the task. Moreover, we discuss how these findings are inconsistent with more traditional theories of memory processing, such as associative interference and spreading activation accounts.
