This chapter summarizes research on analytic versus holistic thinking, including locus of attention, causal perception, perception of change, tolerance of contradiction, and categorization—constructs that are widely studied in social psychology and other related fields, such as consumer psychology. The chapter also reviews the literature on the Analysis-Holism Scale (AHS): how it was developed and how it differs from scales that measure other cultural differences (e.g., individualism versus collectivism; independent versus interdependent self; dialectical versus linear self). Empirical evidence supporting the validity of the AHS in various cognitive domains is introduced. The chapter concludes with a review of recently published papers in which the AHS has been validated and utilized for various purposes.
