Implicit Prejudice

Racial prejudice is a pervasive and pernicious form of intergroup bias. However, a mounting number of studies show that recategorization—even into minimal groups—can overcome the typical consequences of racial and other group classifications. We tested the effects of minimal grouping on implicit prejudice and infrahumanization using a paradigm in which race was orthogonal to group membership. This allowed us to examine whether knowledge of group membership overrides obvious category differences. We found that participants infrahumanized and showed implicit bias toward the minimal outgroup, despite the cross-cutting presence of race, and in fact did not show any of the usual implicit racial bias. In addition, event-related potentials (ERPs) showed an early race effect followed by distinct reactions on the basis of group as processing continued. This is evidence that arbitrary social classifications can engender ingroup preference even in the presence of orthogonal, visually salient categorizations.

Preliminary Study

AbstractObjective:Both bipolar disorder (BD) and schizophrenia (SZ) are associated with language and thought symptoms that probably reflect a semantic memory-related impairment. We conducted a preliminary study to explore the nature of semantic processing in these disorders, using event-related potentials (ERPs).Methods:Twelve patients with BD, 10 patients with SZ and a matched group of 21 healthy controls (HC) underwent EEG recording while they heard sentences containing homophones or control words and performed a semantic ambiguity resolution task on congruent or incongruent targets.Results:Mean N400 amplitude differed between groups for homophones. Patients with SZ made more resolution errors than HC and exhibited a greater N400 congruity effect in ambiguous conditions than BD. In BD, the opposite N400 congruity effect was observed in ambiguous conditions.Conclusion:Results indicated differences in semantic processing between BD and SZ. Further studies with larger populations are needed in order to develop neurophysiological markers of these disorders.Significant OutcomesIn ambiguous conditions, patients with SZ exhibited a greater N400 difference between congruent and incongruent conditions than patients with BD.In ambiguous conditions, patients with SZ exhibited greater N400 amplitude in incongruent conditions than in congruent ones, whereas patients with BD exhibited the opposite N400 congruity effect.Ambiguity resolution results suggest that patients with SZ have difficulty considering the context, while patients with BD overactivate the dominant meaning of homophones and have difficulty inhibiting it.
