Modeling Mate-Choice using Co mputational Temperature and Dynamically Evolving Representations Robert M. French (robert.******@u-) RS, UMR 5022, Dijon, France and Psychology Dept., U. of Liege, 4000 Liege, Belgium Elif T. Kus (elifkus@) Cognitive Science, Bogazi?i University Istanbul, Turkey Abstract We present a model of mate-choice (KAMA) that is based on a gradual, stochastic process of representation- building leading to marriage. KAMA reproduces empirically verifiable population-level mate-selection behavior using individual-level mate-choice mechanisms. Individuals have character profiles, which describe a number of their characteristics (physical beauty, potential earning power, etc.), as well as preference profiles, that specify their degree of preference for those characte ristics in members of the opposite sex. A process of encounters and dating serves to exchange informatio n and allows accurate representations of potential mates to be gradually built up over time. Finally, individuals each have a “temperature”, which is the extent to which they are willing to continue explorin g mate-space. “Temperature” (the inverse of mate “choosiness”) drives individual decision-making in this model. We show that the individual-level mechanisms implemented in the model produce population-level data that qualitatively matches empirical data
