Minority-race children in North America and Europe often show less own-race favoritism than children of the majority (White) race, but the reasons for this asymmetry are unresolved. The present research tested South African children in order to probe the influences of group size, familiarity, and social status on children's race-based social preferences. We assessed South African children's pre...

FUNCTIONAL MAGNETIC RESONANCE IMAGING WAS EMPLOYED TO EXAMINE SENSITIVITY TO SOCIAL EXCLUSION IN THREE CONDITIONS: same-race, other-race, and self-resembling faces. The anterior cingulate cortex (ACC), specifically the dorsal ACC, has been targeted as a key substrate in the physical and social pain matrix and was hypothesized to regulate activation response to various facial conditions. We show...

In the current study, we investigated how complete infant deprivation to out-group race impacts behavioral and neural sensitivity to race. Although monkey models have successfully achieved complete face deprivation in early life, this is typically impossible in human studies. We overcame this barrier by examining youths with exclusively homogenous racial experience in early postnatal developmen...

ABSTRACT Thirty-nine isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in a field in California 2 years after F. oxysporum f. sp. lycopersici race 3 was first observed at that location. These and other isolates of F. oxysporum f. sp. lycopersici were characterized by pathogenicity, race, and vegetative compatibility group (VCG). Of the 39 California isola...

Recent event related brain potential research observed a greater frontal activity to pain expressions of racial in-group than out-group members and such racial bias in neural responses to others' suffering was modulated by task demands that emphasize race identity or painful feeling. However, as pain expressions activate multiple brain regions in the pain matrix, it remains unclear which part o...

How will racial divisions in student friendship networks change as U.S. schools incorporate a growing Asian and Hispanic population? Drawing on theories of race in assimilation processes and the effects of relative group size on intergroup relations, several hypotheses are developed to address this question. These hypotheses are tested using data on friendships among students in grades 7 to 12 ...

This research applies identity theory to understand whether moral identity processes operate similarly or differently depending on group affiliation (gender, race, and religion). A survey measuring facets of the moral identity, moral behavior, and emotions was administered to 315 subjects. Findings support the moral identity as a general human process which does not vary significantly by gender...

Health and socioeconomic disparities tend to be experienced along racial and ethnic lines, but investigators are not sure how individuals are assigned to groups, or how consistent this process is. To address these issues, 1,919 orthodontic patient records were examined by at least two observers who estimated each individual's race and the characteristics that influenced each estimate. Agreement...
