This volume provides an authoritative synthesis of a dynamic, influential area of psychological research. Leading investigators address all aspects of dual-process theories: their core assumptions, conceptual foundations, and applications to a wide range of social phenomena. In 38 chapters, the volume addresses the pivotal role of automatic and controlled processes in attitudes and evaluation; social perception; thinking and reasoning; self-regulation; and the interplay of affect, cognition, and motivation. Current empirical and methodological developments are described. Critiques of the duality approach are explored and important questions for future research identified.
