Knowledge that Transforms

This article examines the role of socioeconomic status (SES) in the relationships among college admissions-test scores, secondary school grades, and subsequent academic performance. Scores on the SAT (a test widely used in the admissions process in the United States), secondary school grades, college grades, and SES measures from 143,606 students at 110 colleges and universities were examined, and results of these analyses were compared with results obtained using a 41-school data set including scores from the prior version of the SAT and using University of California data from prior research on the role of SES. In all the data sets, the SAT showed incremental validity over secondary school grades in predicting subsequent academic performance, and this incremental relationship was not substantially affected by controlling for SES. The SES of enrolled students was very similar to that of specific schools' applicant pools, which suggests that the barrier to college for low-SES students in the United States is a lower rate of entering the college admissions process, rather than exclusion on the part of colleges.

Beliefs in mind-body dualism--that is, perceiving one's mind and body as two distinct entities--are evident in virtually all human cultures. Despite their prevalence, surprisingly little is known about the psychological implications of holding such beliefs. In the research reported here, we investigated the relationship between dualistic beliefs and health behaviors. We theorized that holding dualistic beliefs leads people to perceive their body as a mere "shell" and, thus, to neglect it. Supporting this hypothesis, our results showed that participants who were primed with dualism reported less engagement in healthy behaviors and less positive attitudes toward such behaviors than did participants primed with physicalism. Additionally, we investigated the bidirectionality of this link. Activating health-related concepts affected participants' subsequently reported metaphysical beliefs in mind-body dualism. A final set of studies demonstrated that participants primed with dualism make real-life decisions that may ultimately compromise their physical health (e.g., consuming unhealthy food). These findings have potential implications for health interventions.

Intergenerational decisions affect other people in the future. The combination of intertemporal and interpersonal distance between decision makers in the present and other people in the future may lead one to expect little intergenerational generosity. In the experiments reported here, however, we posited that the negative effect of intertemporal distance on intergenerational beneficence would be reversed when people were primed with thoughts of death. This reversal would occur because death priming leads individuals to be concerned with having a lasting impact on other people in the future. Our experiments show that when individuals are exposed to death priming, the expected tendency to allocate fewer resources to others in the future, as compared with others in the present, is reversed. Our findings suggest that legacy motivations triggered by death priming can trump intergenerational discounting tendencies and promote intergenerational beneficence.

Researchers who study perspective taking are generally optimistic about the potential for interventions to improve intergroup perceptions. The current research provides new insight into the conditions that frame the intergroup outcomes of perspective taking. The results show that the effects of perspective taking are not always positive but depend on perspective takers' degree of identification with the in-group. In two experiments, we demonstrated that adopting the perspective of an out-group member can have damaging effects on intergroup perceptions among group members who are highly identified with the in-group. Specifically, compared with less committed members, those who identified highly with the in-group used a greater number of negative traits to describe the out-group following perspective taking. Such perspective taking also led participants with high in-group identification to judge the out-group less favorably. Understanding how social identity concerns frame the outcome of perspective taking is crucial to its effective employment in intergroup-relations programs.

Chaotic home lives are correlated with behavior problems in children. In the study reported here, we tested whether there was a cross-lagged relation between children's experience of chaos and their disruptive behaviors (conduct problems and hyperactivity-inattention). Using genetically informative models, we then tested for the first time whether the influence of household chaos on disruptive behavior was environmentally mediated and whether genetic influences on children's disruptive behaviors accounted for the heritability of household chaos. We measured children's perceptions of household chaos and parents' ratings of children's disruptive behavior at ages 9 and 12 in a sample of 6,286 twin pairs from the Twins Early Development Study (TEDS). There was a phenotypic cross-lagged relation between children's experiences of household chaos and their disruptive behavior. In genetically informative models, we found that the effect of household chaos on subsequent disruptive behavior was environmentally mediated. However, genetic influences on disruptive behavior did not explain why household chaos was heritable.

Binocular rivalry refers to the unstable perceptual experience that arises when an observer views a different image with each eye: Each image reaches awareness in turn as the other becomes temporarily invisible. Using a novel experimental paradigm, we provide the first direct, perceptual evidence that binocular rivalry occurs only in the presence of attention. Observers in our experiment withdrew attention from a binocular rivalry stimulus shortly after one of the eyes' images was forced to visibility. Seconds later, they shifted attention back to the stimulus to report their perception. For all observers, reported perception strongly and significantly deviated from the results that would be expected if binocular rivalry continued during inattention. Strikingly, reports instead exactly matched those obtained when the stimulus was physically removed for seconds rather than left unattended. These results show that disregarding a binocular rivalry stimulus is equivalent to having it removed from view. Thus, inattention abolishes binocular rivalry.

The social environment requires people to quickly form contextually appropriate social evaluations. Models of social cognition suggest that this ability depends on the interaction of automatic and controlled evaluative systems. However, controlled processes, such as reappraisal of an initial response, have rarely been studied in the context of social evaluation. In the two studies reported here, participants reappraised or simply observed angry or neutral faces. In Study 1, reappraisal modulated evaluations of angry faces on explicit as well as implicit behavioral levels. In Study 2, reappraisal altered both early and late phases of evaluative electrocortical processing. These studies suggest that controlled processes, such as reappraisal, can quickly and substantially modulate early evaluative processes in the context of biologically significant social stimuli.

Wealth inequality has significant psychological, physiological, societal, and economic costs. In six experiments, we investigated how seemingly innocuous, culturally pervasive ideas can help maintain and further wealth inequality. Specifically, we tested whether the concept of choice, which is deeply valued in American society, leads Americans to act in ways that perpetuate wealth inequality. Thinking in terms of choice, we argue, activates the belief that life outcomes stem from personal agency, not societal factors, and thereby leads people to justify wealth inequality. The results showed that highlighting the concept of choice makes people less disturbed by facts about existing wealth inequality in the United States, more likely to underestimate the role of societal factors in individuals' successes, less likely to support the redistribution of educational resources, and less likely to support raising taxes on the rich-even if doing so would help resolve a budget deficit crisis. These findings indicate that the culturally valued concept of choice contributes to the maintenance of wealth inequality.

Myrdal (1944) described the "American dilemma" as the conflict between abstract national values ("liberty and justice for all") and more concrete, everyday prejudices. We leveraged construal-level theory to empirically test Myrdal's proposition that construal level (abstract vs. concrete) can influence prejudice. We measured individual differences in construal level (Study 1) and manipulated construal level (Studies 2 and 3); across these three studies, we found that adopting an abstract mind-set heightened conservatives' tolerance for groups that are perceived as deviating from Judeo-Christian values (gay men, lesbians, Muslims, and atheists). Among participants who adopted a concrete mind-set, conservatives were less tolerant of these nonnormative groups than liberals were, but political orientation did not have a reliable effect on tolerance among participants who adopted an abstract mind-set. Attitudes toward racial out-groups and dominant groups (e.g., Whites, Christians) were unaffected by construal level. In Study 3, we found that the effect of abstract thinking on prejudice was mediated by an increase in concerns about fairness.
