Hereby Department of General Psychology announces that Prof. Stevan HARNAD (Professor of Psychology and Director of Cognitive Sciences Centre at University of Southampton) will be our guest between 17th and 27th October and is going to give a brief couse on FOUNDATIONS OF COGNITION: A SOCIOBIOLOGICAL PERSPECTIVE We, like other species, evolved. And we can think -- in fact, we evolved the ability to think. We also evolved the ability to feel. Why we are afraid of the dark, of snakes, of strangers, of heights; why we feel like eating when our blood sugar goes down, why we overeat, why most of us prefer sex with the opposite sex rather than our own, why we are jealous, why we favour our kin -- all of this can be explained as an evolutionary legacy. What scope does this leave for thinking and freedom of will? These and other questions will be discussed in this seminar on what can and cannot be explained sociobiologically. A good starting paper is: http://www.psych.ucsb.edu/research/cep/primer.htm Note: this is a seminar, not a lecture course.

The topic is: CATEGORISATION, COMMUNICATION AND COGNITION: ON THE ADVANTAGES OF SYMBOLIC THEFT OVER SENSORIMOTOR TOIL To categorise is to respond differentially to certain kinds of input. This is a very general cognitive capacity, covering everything from Pavlovian and instrumental responding to the chess master pondering how to respond to a chess move and the physicist inferring the existence of quarks. Once a categoriser has a repertoire of categories grounded through trial and error sensorimotor interaction ("honest toil"), higher-order categories can be formed in two ways: through further sensorimotor interaction, as with the ground-level categories, or through symbolic interaction with other categorisers, based on combining and recombining the names of lower-order categories into propositions describing new higher-order categories ("theft"). I will present some behavioural and computational data comparing these two strategies. Some related papers that can be found at my Web site: http://cogsci.soton.ac.uk/~harnad/genpub.html Harnad, S.
