An integrative model of human response processes in Raven's Matrices

This paper presents Xyrast, an integrative model of human response processes on the Raven's Matrices family of fluid intelligence tests, and reports on a simulation study addressing its response characteristics and verisimilitude. Xyrast is implemented in the Clarion cognitive architecture and models the influence of response strategy, working memory capacity, and persistence on performance. Simulations suggest that the model captures a wide range of phenomena offering, in some cases, novel explanations for observed results. These findings suggest several avenues for future research.
