Collaborative Memory Foraging in Categorical Recall Tasks

Abstract

A classic paradigm for investigating memory is the category recall task, where participants recall as many items as possible from a given category, within some time window. Category recall tasks have been used to investigate memory as a search process, where memory is conceptualized as a landscape with distributed resources (resources being the target items of memory recall). Rhodes and Turvey (2007) show that the dynamics of memory search are akin to animal foraging behavior. Specifically, patterns of recall exhibited Lévy processes, which have been observed in many species and at many scales, and are hypothesized to be optimal under certain conditions. Here, we investigate the effects of social context on Lévy processes using a collaborative category recall task. Although the processes of collaborative recall may differ from individual recall, our results suggest that the products of that recall are similar.
