"The research presented here is important for three reasons. First, it sets a standard for rigor, parsimony and theoretical elegance in cognitive modeling. Second. . . it offers a coherent and predictive system for tackling both specific and general issues. Third, it provides formal tools for quantitative modeling of complex systems that researchers in many fields could effectively borrow."--Science

"The book serves as a summary of the empirical and theoretical underpinnings of current ideas in classification and cognition....Estes appears at his best when articulating the limitations and merits of each approach.--Psychological Reports
