Vancouver Studies in Cognitive Science is an interdisciplinary series bringing together topics of interest to psychologists, philosophers, cognitive scientists, and linguists. Each volume is based on conferences organized at Simon Fraser University, with chapters added from nonparticipants to ensure balanced and adequate coverage from the topic under study. The fifth volume examines the role of perception in cognitive psychology in light of recent events. Despite the wide scope of the intended topic, however, papers presented at the conference and solicited for this text all focus on fundamental questions about the nature of visual perception, specifically concerning the form and content of visual representations.
