This study examined the influences of racial discrimination and different racial identity attitudes on engaging in violent behavior among 325 African American young adults. The contributions of racial discrimination and racial identity attitudes in explaining violent behavior during the transition into young adulthood while controlling for the influences of prior risk behaviors at ninth grade were examined separately for males and females. In addition, the buffering effects of racial identity attitudes on the relationship between racial discrimination and violent behavior were tested. Results indicated that experience with racial discrimination was a strong predictor of violent behavior, regardless of gender. The centrality of race for males and the meaning others attribute to being Black for both males and females were moderators of the influence of racial discrimination on violent behavior. 相似文献

This study examined racial identity and parental support as predictors of alcohol use in a sample of 488 African American adolescents. Two dimensions of racial identity were investigated: (1) racial centrality (i.e., the significance that one places on race in defining oneself) and (2) private regard (i.e., the extent to which one feels positively about Black people). In addition, perceived support from mothers and fathers was examined. Multivariate results showed that private regard and father support were associated with less self-reported alcohol use after partialling out the effects of age and gender. An interaction between the two racial identity dimensions was also found such that private regard was associated with less alcohol use for adolescents who reported that race was a more central part of their identity. 相似文献

Prompts to regulate emotions improve the impact of health messages on eating intentions and behavior
Krista Caldwell Sherecce Fields Heather C. Lench Talya Lazerus 《Motivation and emotion》2018,42(2):267-275
The current study examined the effect of emotion regulation prompts on obesity-related behavioral intentions and food choices in a sample of undergraduate students. Prior to reading a pamphlet regarding obesity-related health concerns and healthy food choices, participants were prompted to regulate their emotions or no prompt was given. Study 1 investigated differences in health behavior intentions and perception of risk of obesity-related health concerns. Study 2 examined differences in meal choices from a menu. Finally, Study 3 examined differences in food choices between participants prompted to attend, regulate emotions, or no prompt. Participants prompted to regulate their emotions were more likely to report intentions to follow a healthier diet and perceive a greater likelihood of health concerns, select health food options from a presented menu. and select a healthier food choice from presented options. These findings suggest emotion regulation strategies may be beneficial to increase awareness of perceived health risks as well as encourage healthier lifestyle choices among college students. 相似文献

If food pilferage has been a reliable selection pressure on food caching animals, those animals should have evolved the ability to protect their caches from pilferers. Evidence that animals protect their caches would support the argument that pilferage has been an important adaptive challenge. We observed naturally caching Eastern grey squirrels (Sciurus carolinensis) in order to determine whether they used any evasive tactics in order to deter conspecific and heterospecific pilferage. We found that grey squirrels used evasive tactics when they had a conspecific audience, but not when they had a heterospecific (corvid) audience. When other squirrels were present, grey squirrels spaced their caches farther apart and preferentially cached when oriented with their backs to other squirrels, but no such effect was found when birds were present. Our data provide the first evidence that caching mammals are sensitive to the risk of pilferage posed by an audience of conspecifics, and that they utilise evasive tactics that should help to minimise cache loss. We discuss our results in relation to recent theory of reciprocal pilferage and compare them to behaviours shown by caching birds. 相似文献

Depression is a prevalent issue for women on college campuses. Undergraduate women participated in (a) an aerobic exercise class, (b) a weight‐lifting class, or (c) a control group to determine the effect of exercise on depressive symptoms. Participants in the aerobic exercise group exhibited a significant decrease in depressive symptoms. Implications for college counselors are discussed. 相似文献

It has been proposed that the uniqueness of human cumulative culture may be attributable to humans' greater orientation toward copying the process of behavior (imitation), as compared with the products (emulation), resulting in particularly high fidelity transmission. Following from previous work indicating that adult human participants can exhibit cumulative learning on the basis of product copying alone, we now investigate whether such learning involves high fidelity transmission. Eighty adult human (Homo sapiens) participants were presented with a task previously shown to elicit cumulative learning under experimental conditions, which involved building a tower from spaghetti and modeling clay. Each participant was shown two completed towers, ostensibly built by previous participants, but actually built to prespecified designs by the experimenter. This end state information was provided either in the form of photographs, or the presence of actual towers. High fidelity matching to these end states was apparent in both demonstration conditions, even for a design that was demonstrably suboptimal with regard to the goal of the task (maximizing tower height). We conclude that, although high fidelity transmission is likely to be implicated in cumulative culture, action copying is not always necessary for this to occur. Furthermore, since chimpanzees apparently copy behavioral processes and well as products, and also transmit behavior with high fidelity, the stark absence of unequivocal examples of cumulative culture in nonhumans may be attributable to factors other than imitative ability. 相似文献

Effective treatment programs for violent adolescents: Programmatic challenges and promising features
The search for effective treatment programs for violent adolescent offenders has produced more questions than answers. Only a handful of treatment programs have proven efficacious with adolescent offenders. This paper reviews the similarities and common features of four programs that have proven effective at reducing recidivism in adolescent offenders. The programs not only differ in many ways, but they also share some striking similarities. All take a comprehensive approach; utilizing a multidimensional treatment system to work with the youth and their family. All share a similar philosophy, theoretical framework, and structural approach to treatment. These similarities provide a template to facilitate progress in future programming, and research. 相似文献

ABSTRACT Rates of gambling problems in older adults have risen with increased accessibility of gambling venues. One possible contributor to problem gambling among older adults is decreased self-control brought about by diminished executive functioning. Consistent with this possibility, Study 1 revealed that older adults recruited from gambling venues reported greater gambling problems if they also experienced deficits in executive functioning, measured via the Trail Making Test. Study 2 replicated this finding and demonstrated that problem gambling is associated with increased depression among older adults, mediated by increased financial distress. These studies provide support for the hypothesis that older adult gamblers who have executive functioning problems are also likely to have gambling problems. 相似文献

Muscular output was measured in terms of strength, endurance, impulse, and recovery, with 10 Ss, 4 times per day over 15 successive days. A general index (the mean percentage of baseline performance with all measures) indicated that performance generally improved over the first 5 or 6 days, and remained relatively stable thereafter. The measures of strength were sensitive to within-day effects, whereas endurance and recovery measures were not influenced by such circadian rhythms. 相似文献
