Bücher von Leon Festinger

Kaum eine Theorie hat innerhalb der Psychologie und besonders innerhalb der Sozialpsychologie derart umfangreiche Forschungen angeregt und Kontroversen ausgelöst: Leon Festingers erstmals 1957 publizierte Theorie der Kognitiven Dissonanz wurde inzwischen in unzähligen Experimenten bestätigt und von Psychologen weltweit weiterentwickelt. Sie gilt zurecht als ein Meilenstein der modernen Psychologie.

Leon Festinger's theory of cognitive dissonance has been widely recognized for its important and influential concepts in areas of motivation and social psychology. The theory of dissonance is here applied to the problem of why partial reward, delay of reward, and effort expenditure during training result in increased resistance to extinction. The author contends that a state of impasse exists within learning theory largely because some of its major assumptions stand in apparent opposition to cetain well-established experimental results. The book puts forward a new theory that seems to reconcile these data and assumptions. This new theory can account for data with which other theories have difficulty: it integrates empirical phenomena that have been regarded as unrelated, and it is supported by the results of experiments designed specifically to test its implications. These experiments are fully described in the text.

The study reported in this volume grew out of some theoretical work, one phase of which bore specifically on the behavior of individuals in social movements that made specific (and unfulfilled) prophecies. We had been forced to depend chiefly on historical records to judge the adequacy of our theoretical ideas until we by chance discovered the social movement that we report in this book.
