First published in 1976. This volume presents the collected papers of the Eleventh Annual Symposium on Cognition, held at Carnegie-Mellon University in April, 1975. These papers are unique in the history of these symposia for their orientation toward the study of social behavior. This symposium brings together the two fields of social psychology and cognitive psychology in response to a growing desire among many social psychologists to seek out or develop a more systematic body of theory, and a corresponding desire among many cognitive psychologists to study the everyday affairs of people outside the laboratory.
