Recently, there has been increasing interest in how emotions affect decision making. In particular, how does emotion interact with cognition when people make decisions? The work of Carlos A. Trujillo represents a bold attempt to illuminate the interplay between cognitive and emotional factors when people are involved in this important activity. His contribution is both empirical and theoretical. Trujillo reports the results of five experiments and then goes on to develop an organizing framework. His results are informative and his work is innovative. It defines both new paths and challenges for further investigation into the mysteries of the mind. By: Robin M. Hogarth (ICREA Research Professor, Universitat Pompeu Fabra, Barcelona) In this work, particular attention is paid to the role of meta cogitive activities, the situational cognitive capacities of individuals and the way people produce and employ categorical information. Results are of interest for behavioral decision scientists, management and marketing researchers.
