Neural correlates of individual differences in retrieval cue processing

Abstract

Event Abstract Back to Event Neural correlates of individual differences in retrieval cue processing Emma K. Bridger1*, J. E. Herron1 and E. L. Wilding1 1 School of Psychology, Cardiff University, United Kingdom It is generally assumed that strategic processes that are engaged at the time of retrieval benefit the accuracy of memory judgments. There is, however, little direct evidence to support this assumption. In event-related potential (ERP) studies, indices of strategic retrieval processing have been obtained by contrasting the activity that is elicited by items with no study history (new items) across tasks with different retrieval demands. It has been argued that since these classes of items have not been encountered in prior study phases, any differences between the neural activities that they elicit are likely to reflect task-specific operations that are engaged in service of retrieval. In no studies to date, however, has it been possible to claim that these markers of retrieval processing influence the accuracy of memory judgments. The experiment reported here was designed in order to determine whether this is in fact the case. Toward this end, participants completed two memory tasks, thereby permitting comparisons between new item ERPs across situations in which retrieval demands differed. The degree to which task-specific retrieval processing was engaged was operationalised as the magnitude of the differences between the new item ERPs elicited in the two tasks. There was a positive correlation between response accuracy and the magnitude of this ERP measure of task-specific retrieval processing. The data provides the first compelling demonstration that strategic retrieval processing benefits memory accuracy.
