RESUMO
Across seven preregistered studies in online adult volunteer samples (N = 5,323), we measured implicit evaluations of social groups following exposure to historical narratives about their oppression. Although the valence of such information is highly negative and its interpretation was left up to participants, implicit evaluations of oppressed groups shifted toward positivity, including in designs involving fictitious, well-known, and even self-relevant targets. The sole deviation from this pattern was observed in an experiment using a vignette about slavery in the United States, in response to which neither White nor Black Americans exhibited any change in implicit race attitudes. In line with propositional perspectives, these findings suggest that implicit evaluations (including, notably, implicit evaluations of well-known and self-relevant social groups) tend to change toward positivity in response to extremely negative information involving past oppression. However, macro-level phenomena, such as public awareness of histories of oppression, can modulate such updating processes.

When the economy declines, racial minorities are hit the hardest. Although existing explanations for this effect focus on institutional causes, recent psychological findings suggest that scarcity may also alter perceptions of race in ways that exacerbate discrimination. We tested the hypothesis that economic resource scarcity causes decision makers to perceive African Americans as "Blacker" and that this visual distortion elicits disparities in the allocation of resources. Studies 1 and 2 demonstrated that scarcity altered perceptions of race, lowering subjects' psychophysical threshold for seeing a mixed-race face as "Black" as opposed to "White." In studies 3 and 4, scarcity led subjects to visualize African American faces as darker and more "stereotypically Black," compared with a control condition. When presented to naïve subjects, face representations produced under scarcity elicited smaller allocations than control-condition representations. Together, these findings introduce a novel perceptual account for the proliferation of racial disparities under economic scarcity.

Based on recent research, I propose that threat stemming from the environment, perceivers, and targets distorts the visual perception of racial minorities in ways that facilitate discrimination. This model synthesizes the growing motivated race perception literature, generates new hypotheses about threat-induced discrimination, and reveals barriers to discrimination intervention.

Multiracial individuals are often categorized as members of their 'socially subordinate' racial group-a form of social discrimination termed hypodescent-with political conservatives more likely than liberals to show this bias. Although hypodescent has been linked to racial hierarchy preservation motives, it remains unclear how political ideology influences categorization: Do conservatives and liberals see, feel or think about mixed-race faces differently? Do they differ in sensitivity to Black prototypicality (i.e. skin tone darkness and Afrocentric features) or racial ambiguity (i.e. categorization difficulty) of Black/White mixed-race faces? To help answer these questions, we collected a politically diverse sample of White participants and had them categorize mixed-race faces as Black or White during functional neuroimaging. We found that conservatism was related to greater anterior insula activity to racially ambiguous faces, and this pattern of brain activation mediated conservatives' use of hypodescent. This demonstrates that conservatives' greater sensitivity to racial ambiguity (rather than Black prototypicality) gives rise to greater categorization of mixed-race individuals into the socially subordinate group and tentatively suggests that conservatives may differ from liberals in their affective reactions to mixed-race faces. Implications for the study of race categorization and political psychology are discussed. This article is part of the theme issue 'The political brain: neurocognitive and computational mechanisms'.

When economic resources are scarce, racial minorities are often devalued and disenfranchised. We proposed that this pattern extends to visual processing, such that the encoding of minority group faces is disrupted under scarcity-an effect that may facilitate discrimination and contribute to racial disparities. Specifically, we used EEG and fMRI to test whether scarce economic conditions induce deficits in neural encoding of Black faces, and we examined whether this effect is associated with discriminatory resource allocation in behavior. In Study 1, framing resources as scarce (vs. neutral) selectively impaired the neural encoding of Black (vs. White) faces, as indexed by a delayed face-related N170 ERP response, and the degree of this encoding deficit predicted anti-Black allocation decisions. In Study 2, we replicated and extended this effect using fMRI: Resources framed as scarce (vs. neutral) reduced face-sensitive fusiform activity to Black (vs. White) faces. Furthermore, scarcity-decreased fusiform activity to Black faces corresponded with decreased valuation-related striatum activity to predict anti-Black allocation decisions. These findings suggest that impaired visual processing and devaluation occur selectively for minorities under scarcity-an implicit effect that may promote discrimination and contribute to rising disparities observed during economic stress.

When the economy declines, existing racial disparities typically expand, suggesting that economic scarcity may promote racial discrimination. To understand this pattern, we examined the effect of perceived scarcity on resource allocations to Black and White American recipients, and tested whether this effect depends on a decision maker's motivation to respond without prejudice. We proposed that scarcity would lead to increased discrimination among those with relatively low internal motivation but not those high in internal motivation. Indeed, we found that when resources were framed as scarce (vs. abundant or a control condition), low-motivation participants allocated less to Black than White recipients, whereas high-motivation participants allocated more to Black than White recipients (Studies 1 and 2). This pattern was strongest when decisions could be made deliberatively (Study 3), and anti-Black allocation bias emerged even in a non-zero-sum context (Studies 4 and 5), suggesting a strategic bias directed against Black recipients rather than in favor of White recipients. These findings indicate that the psychological perception of scarcity can produce racial bias in the distribution of economic resources, depending on the motivations of the decision maker-an effect that may contribute to the increase in racial disparities observed during economic stress.

Disruption of function of left, but not right, lateral prefrontal cortex (LPFC) with low-frequency repetitive transcranial magnetic stimulation (rTMS) increased choices of immediate rewards over larger delayed rewards. rTMS did not change choices involving only delayed rewards or valuation judgments of immediate and delayed rewards, providing causal evidence for a neural lateral-prefrontal cortex-based self-control mechanism in intertemporal choice.
