Originally published in 1981, this volume presents the domain of personality as a fuzzy set that includes features previously identified with cognitive and social psychology. Few of the individual contributions are centrally concerned with individual differences and cross-situational stability, but these traditional themes certainly appear in several of the chapters. The remaining chapters deal with the general processes mediating the interaction between the person and the social environment, filling out the fuzzy set of personality psychology.Part 1 seeks to locate contemporary trends in the cognitive psychology of personality against a backdrop of historical events. The chapters in Part 2 discuss some of the cognitive processes mediating social behaviour. Part 3 contains contributions concerned with the rules by which people make judgments about objects in the social world. The self, a dominant topic in personality theory and research, is treated extensively in Part 4. Although many of the chapters are explicitly concerned with the relations between cognition and action – after all, most human interaction takes the form of judgments and communication – the contributions in Part 5 make the links to overt behaviour. Finally, Part 6 offers two discussions of the previous contributions from the perspective of cognitive psychology.
