Essentialism goes social: Belief in social determinism as a component of psychological essentialism.

Individuals tend to explain the characteristics of others with reference to an underlying essence, a tendency that has been termed psychological essentialism. Drawing on current conceptualizations of essentialism as a fundamental mode of social thinking, and on prior studies investigating belief in genetic determinism (BGD) as a component of essentialism, we argue that BGD cannot constitute the sole basis of individuals' essentialist reasoning. Accordingly, we propose belief in social determinism (BSD) as a complementary component of essentialism, which relies on the belief that a person's essential character is shaped by social factors (e.g., upbringing, social background). We developed a scale to measure this social component of essentialism. Results of five correlational studies indicate that (a) BGD and BSD are largely independent, (b) BGD and BSD are related to important correlates of essentialist thinking (e.g., dispositionism, perceived group homogeneity), (c) BGD and BSD are associated with indicators of fundamental epistemic and ideological motives, and (d) the endorsement of each lay theory is associated with vital social-cognitive consequences (particularly stereotyping and prejudice). Two experimental studies examined the idea that the relationship between BSD and prejudice is bidirectional in nature. Study 6 reveals that rendering social-deterministic explanations salient results in increased levels of ingroup favoritism in individuals who chronically endorse BSD. Results of Study 7 show that priming of prejudice enhances endorsement of social-deterministic explanations particularly in persons habitually endorsing prejudiced attitudes.

The Neuroanatomical Basis of Understanding Sarcasm and Its Relationship to Social Cognition.

The authors explored the neurobiology of sarcasm and the cognitive processes underlying it by examining the performance of participants with focal lesions on tasks that required understanding of sarcasm and social cognition. Participants with prefrontal damage (n = 25) showed impaired performance on the sarcasm task, whereas participants with posterior damage (n = 16) and healthy controls (n = 17) performed the same task without difficulty. Within the prefrontal group, right ventromedial lesions were associated with the most profound deficit in comprehending sarcasm. In addition, although the prefrontal damage was associated with deficits in theory of mind and right hemisphere damage was associated with deficits in identifying emotions, these 2 abilities were related to the ability to understand sarcasm. This suggests that the right frontal lobe mediates understanding of sarcasm by integrating affective processing with perspective taking. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
