Sci-Math Seminar Speaker: Diane Donovan, University of Queensland Title: Studying Cognitive Complexity by Analyzing the Intrinsic Structure of A Latin Square Date: Thu 22 June, 2006 Time: 16:45 Place: Science Building, Room Z42 Abstract: Using recent advances in relational complexity theory, cognitive psychologists are endeavoring to advance their understanding of cognitive processing by studying the mathematical structure of a latin square. A partial latin square is an n x n array in which each of the numbers 1 to n occurs at most once in each row and at most once in each column. By abstracting into the mathematical theory the psychologists are endeavoring to grade “cognitive reasoning tests” on a strictly increasing scale. In this talk I will discuss the underlying mathematical ideas behind this study, and show have the intrinsic structure of a latin square not only answers some of the psychologists questions but also raises further questions, challenging their assumptions.
