Processus automatiques dans la formation d'attitudes implicites vis à vis de l'alcool : études expérimentales de l'effet de l'exposition incidente à l'alcool dans les médias

Abstract : This thesis focuses on the influence of alcohol sport sponsorship and alcohol consumption in movies on implicit attitudes towards alcohol. Few researches have focused on the mediating psychological mechanisms between exposure to alcohol promotion in media and long-term consumption. Our hypothesis is that evaluative conditioning through affect misattribution mediatizes the effect of exposure to alcohol stimuli on implicit attitudes toward alcohol. The effect of two other automatic processes (i.e. mere exposure effect, association with the self) are also studied. Two studies (1 and 2) were led to test an induction that (i) impairs controlled processes and (ii) maximizes affect misattribution by inhibiting attentional control in an evaluative condition paradigm. Three studies on alcohol sponsorship were then led in which we found a main effect of on implicit attitudes (studies 3 and 5). A mere exposure effect was observed in the study 5, but we found no convincing evidence for evaluative conditioning (study 4). However, we found an evaluative conditioning effect in two studies on alcohol consumption in movies and TV shows which was shown to be independent from association with the self (study 6), as well as relying on controlled processes (study 7). Overall, sponsorship effects on implicit attitudes seems to occur via a mere exposure effect, while alcohol portrayals in movies seems to impact implicit attitudes toward alcohol through evaluative conditioning and association of alcohol with the self.
