In previous studies, we identified that electrophysiological measures associated with recognition memory (FN400 and LPC) and working memory (CDA) were sensitive to memory set size during a modified hybrid search task.
The goal of the current study is to use these components to test the model of hybrid search outlined in Cunningham and Wolfe (2014). Specifically, when searching for a categorical target set (e.g., dogs), we propose that a memory search will occur only when the candidate item is identified as a member of the target category. For items that are similar to the target category (e.g., cats), we predict that a memory search will occur when the target set is large.
