    Assuming that boys are better at math than girls, expecting that Swiss people love to eat chocolate, or inferring that senior citizens are not at ease with new technologies, all reflect stereotypical expectations about specific social categories. The term “stereotype” refers to shared sets of expectancies about the likely personality, behaviors, preferences, or physical features of social category members. From a cognitive perspective, stereotypes are energy saving devices – mental shortcuts – that allow perceivers to spare processing costs when navigating their complex social environment. Yet, inferring people’s preferences, behaviors, or personality from their category membership can also lead to incorrect predictions, to offensive assumptions, or even to discriminatory behaviors. The present dissertation aims to shed light on the mechanisms by which we form expectations about social categories, and how these expectations impact information processing. Specifically, the first part of this dissertation provides a developmental perspective on how children learn about social categories. It specifically examines how children learn to make inferences about social categories, and the conditions under which children start attributing properties to social category members. The second part of this dissertation turns to the resulting stereotypes that adults hold about social categories, and how these stereotypes modulate information processing. This part focuses on the mental processes that underlie stereotyping and assesses how the processing of written texts is affected by items that confirm versus contradict stereotypical expectations. Together, this dissertation provides a cognitive and developmental perspective on the acquisition of stereotypes and their later effects on information processing. In doing so, this dissertation will hopefully bring a better comprehension of the foundational cognitive processes that underlie stereotyping and its consequences.

    Social cognition and Relevance: How stereotypes impact the processing of definite and indefinite descriptions

    This paper focuses on the impact of social cognition on thes processing of linguistic information. More specifically, it brings some insights to Relevance theory's construal of MeaningNN, which seeks to account for non-propositional meanings. It shows, through two experiments, how gender and nationality-related stereotypes guide the processing of definite and indefinite descriptions. Experiment 1 consists of a self-paced reading task (with 59 French native speakers), introducing information confirming vs. violating gender stereotypes within a nominal phrase (NP). The NP (e.g., “chirurgien/chirurgienne”, “surgeonmale/female”) was itself introduced either by a definite article (presupposition) or an indefinite article (assertion). Results showed that information violating gender stereotypes was costlier to process than stereotype-congruent information. Moreover, when information violated gender stereotypes, definite descriptions became significantly costlier than indefinite ones, because they required the identification of a salient referent which contradicted stereotypical expectations. Experiment 2 tested the effects of definite vs. indefinite NP on processing nationality-related stereotypes in a self-paced reading task (with 49 French native speakers). Participants read definite vs. indefinite NPs referring to representatives of a country. The NP was subsequently paired with information that confirmed vs. contradicted nationality stereotypes. Results showed that information contradicting nationality stereotypes were significantly costlier to process than information confirming stereotypes. Furthermore, when information contradicted nationality stereotypes, indefinite descriptions (which promote a single occurrence reading) failed to facilitate information processing compared to definite descriptions (which promote a generalized representation of the social category). Overall, the present findings are consistent with research on stereotypes, in that they show that stereotype-incongruent information affect sentence processing. Importantly, while Experiment 1 revealed that stereotypes affected the processing of linguistic markers, Experiment 2 suggested that linguistic markers could not modulate the processing of stereotypes.
