Process versus content in eyewitness metamemory monitoring.

Abstract

Three studies (Ns = 200, 135, and 187 college undergraduates) contrasted process versus content accounts of eyewitness metamemory monitoring. Subjective vividness, a cue related to memory content, was a better predictor of confidence and accuracy than were cues related to the retrieval process. Participants who were asked to recall, rather than recognize, event details displayed greater insight into accuracy, primarily because vividness was a more valid accuracy cue under recall conditions. Results reinforce the value of recall-based protocols for eliciting eyewitness testimony and suggest some specific conditions (e.g., yes-no recognition) under which investigators should be especially cautious in relying on confidence to infer accuracy. In addition, results point to a general framework for understanding moderating effects on eyewitness metamemory accuracy.
