The Golden Rule, a core precept of many religions, emphasizes the importance of treating others with compassion. We examined whether priming Golden Rule messages would influence Buddhists’ and Christians’ attitudes toward gay people and perceptions that homosexuality is a choice. In a priming task, participants filled in missing words for popular quotations including two Golden Rule messages that were attributed to either Buddha or Jesus. Christians ( N = 585) in the Buddha‐attributed Golden Rule condition showed stronger explicit anti‐gay attitudes and were more likely to agree that homosexuality is a choice than Christians in the Jesus‐attributed or control conditions, = .012, = .035, even after controlling for political orientation and religiosity. Buddhists ( = 394) showed no variation in attitudes across priming conditions, = .001, = .78. Our results suggest that although the Golden Rule has an important influence on believers, its message of compassion may produce more prejudice if it comes from an outgroup source compared to an ingroup source. 相似文献

This paper examines if perceptions of test legitimacy increase when racial differences on test performance match the racial status quo or when a perceiver's in‐group performs better than expected, relative to other groups. Study 1 assesses expected performance difference for various racial groups on a GRE‐like test. Study 2 assesses White and Asian participants' perceptions of legitimacy of a test that either favors the in‐group or an out‐group. Study 3 replicates Study 2 using individuals from high‐ and low‐status groups (Asians and Latinos, respectively). The findings suggest that the desire to benefit the in‐group trumps the desire to justify the status quo in accounting for the impact of race‐based performance differences on perceptions of test legitimacy. 相似文献

Prolonged institutional rearing is associated with atypically large amygdala volume and difficulties in emotion regulation 总被引:1,自引:0,他引:1

Early adversity, for example poor caregiving, can have profound effects on emotional development. Orphanage rearing, even in the best circumstances, lies outside of the bounds of a species-typical caregiving environment. The long-term effects of this early adversity on the neurobiological development associated with socio-emotional behaviors are not well understood. Seventy-eight children, who include those who have experienced orphanage care and a comparison group, were assessed. Magnetic resonance imaging (MRI) was used to measure volumes of whole brain and limbic structures (e.g. amygdala, hippocampus). Emotion regulation was assessed with an emotional go-nogo paradigm, and anxiety and internalizing behaviors were assessed using the Screen for Child Anxiety Related Emotional Disorders, the Child Behavior Checklist, and a structured clinical interview. Late adoption was associated with larger corrected amygdala volumes, poorer emotion regulation, and increased anxiety. Although more than 50% of the children who experienced orphanage rearing met criteria for a psychiatric disorder, with a third having an anxiety disorder, the group differences observed in amygdala volume were not driven by the presence of an anxiety disorder. The findings are consistent with previous reports describing negative effects of prolonged orphanage care on emotional behavior and with animal models that show long-term changes in the amygdala and emotional behavior following early postnatal stress. These changes in limbic circuitry may underlie residual emotional and social problems experienced by children who have been internationally adopted. 相似文献

While there is great deal of research that tracks self-regulatory academic beliefs and behaviors of students, relatively few
efforts examine the specific self-beliefs of high achieving African American students. This study compared the intelligence-related
beliefs, efficacy beliefs and academic goal orientations of 257 African American (N = 196) and White (N = 61) sophomore and senior students from among honors-level language arts classes in three large midwestern high schools.
The results of this study suggest that while African American students and their White peers do not significantly differ with
respect to efficacy beliefs or goal orientation, African American students expressed more strongly-held beliefs that were
consistent with an entity view of intelligence than did White students. The implications of these results are discussed, as
well as a practical means of application for academic settings. 相似文献

Latent inhibition refers to learning that some stimuli are not signals of important events. It has been widely studied in
vertebrates, but it has been substantially less well studied in invertebrates. We present an investigation into latent inhibition
in the honey bee (Apis mellifera) using a proboscis extension response conditioning procedure that involved ‘preexposure’ of an odor without reinforcement
prior to appetitive conditioning. A significant latent inhibition effect, measured in terms of a reduction in acquisition
performance to the preexposed odor, was observed after 8 unreinforced presentations, and the effect continued to increase
in strength up to 30 presentations. We also observed that memories formed for the preexposed odor lasted at least 24 h. Further
manipulation of interstimulus interval and the visual conditioning context partially attenuated the effect. The latter results
indicate that latent inhibition in honey bees may not be a unitary phenomenon. Two different mechanisms may be required, in
which one mechanism is dependent on the visual context and the second is not. 相似文献

Inhibitory control has been suggested as a key predictive measure of problem-solving skills in human and nonhuman animals. However, there has yet to be a direct comparison of the inhibitory skills of the nonhuman apes and their development in human children. We compared the inhibitory skills of all great ape species, including 3–5-year-old children in a detour-reaching task, which required subjects to avoid reaching directly for food and instead use an indirect reaching method to successfully obtain the food. We tested 22 chimpanzees, 18 bonobos, 18 orangutans, 6 gorillas and 42 children. Our sample included chimpanzees, bonobos and orangutans housed in zoos (N = 27) and others housed in sanctuaries in their native habitats (N = 37). Overall, orangutans were the most skilful apes, including human children. As expected older children outperformed younger children. Sanctuary chimpanzees and bonobos outperformed their zoo counterparts whereas there was no difference between the two orangutan samples. Most zoo chimpanzees and bonobos failed to solve the original task, but improved their performance with additional training, although the training method determined to a considerable extent the level of success that the apes achieved in a transfer phase. In general, the performance of the older children was far from perfect and comparable to some of the nonhuman apes tested. 相似文献

There are three outstanding issues raised by my critics in this volume. The first concerns the nature and status of universals (John Heil). The second is ‘the essential problem’, which is the issue of how to distinguish the essential properties of natural kinds from their accidental ones, and the related question of whether we really need to believe in the essences of natural kinds (Stephen Mumford). The third is that of strong versus weak dispositional essentialism (Alexander Bird), or equivalently, whether there is any place for categorical properties in an essentialist metaphysic (John Heil). This paper addresses these three issues. 相似文献
