L'âgisme : étude de la nature, des théories explicatives et des mesures directes et indirectes d'un phénomène psychosocial

Abstract : What is the real nature of ageism? How do we explain and measure it? Here are the three main questions which have guided our work. We have tried to study this phenomenon from the theories and most recent paradigms perspectives of the social cognition whether they are explicit or implicit. The thesis is divided in two parts: One is theoretical while the other one is empirical. In the first one, we have tried to explore the nature of ageism: Is it an attitude, a stereotype? How does it function? How does it act? How do we explain it? Several explicative theories have been explored such as the social cognitive perspective of age stereotypes, the social identity theory, the double standard of aging and the terror management theory without omitting the role of certain aspects of personality in the individual differences linked to ageism. Another important factor is the implicit ageism as seen in the implicit social cognition. The second part deals with 6 empirical studies. The first two parts are about explicit ageism and try to adapt and validate a direct measure on ageism. This measure is therefore integrated to a structural model which includes certain personality variables related to generalized prejudice. To our knowledge, we introduce through this study the first French direct measure on ageism duly validated. The other four experimental studies deal with implicit ageism when the first two studies concerned the construction and validation of an indirect measure of ageism. We have used the Single Category Implicit Association Test (SC-IAT) to build an absolute indirect measure as opposed to a relative measure produced by the famous Implicit Association Test (IAT). The third study explores the implicit ageism through the paradigm of multiple stereotypes due to age and terror management theory. Finally, the last one explores implicit ageism through the double standard of aging.
