Lambert et al. (2003) suggested that stereotyping could be thought of as automatic (implicit) responses that may become magnified in certain social settings through a loss of cognitive control. This type of explanation seems reasonable; however, to date, no attempts have been made to provide a more thorough, mechanistic (computational) explanation of the exact processes underlying the phenomenon. This paper proposes just such a detailed explanation using the CLARION cognitive architecture. Our CLARION-based theory takes into account motivational factors as well as the interaction between explicit and implicit processes and is used to provide a plausible interpretation of data from an identification task in Lambert et al. (2003).
