Effets comportementaux et cognitifs de l'engagement dans un acte préparatoire activant un élément central versus périphérique de la représentation du don d'organes

We render an account of a research programme that links two fields of study usually unconnected: the field of the freely agreed submission and the field of social representations. Two hypothesis are tested in the foot-in-the door paradigm: participants that agree to perform an initial request (to sign a petition) that selects a core element of the representation of organ donation: a) will be more inclined to agree to perform the target request (to sign a donor card); and b) will have an attitude more favourable about organ donation than participants that agree to perform an initial request that selects a peripheral element. The two experiments presented confirm these hypotheses.
