For the past several years, two themes have united my research in Cognitive Psychology. First, I'm interested in how people acquire, organize, and utilize real-world knowledge (i.e., facts about the world learned through experience). Second, I have been developing a general multiple-strategies approach to mnemonic and numerical judgement. This approach is concerned with identifying strategies people use when they perform a given judgement task, characterizing behavioral consequences of competing strategies, specifying factors that influence strategy selection, and improving estimation performance. Currently, I am conducting a variety of projects directly related to one or both of these themes. These projects deal with the following topics: Organization of personal events in autobiographical memory Autobiographical memory, historical processes, & collective memory Representation and use of information about event frequencies Representation and use of geographical knowledge Knowledge-based updating of real-world knowledge Knowledge-based and conversational accounts of judgmental biases Risk perception and learning Email: norman.brown@ualberta.ca     Phone: (780)492-4604   Fax: (780)492-1768 P538 Department of Psychology, University of Alberta, Edmonton, AB, Canada, T6G 2E9
