The aim of the present study was to examine racial differences in women’s attitudes toward lesbians and gay men and to offer an understanding of these differences. Participants were 224 18–30 year old heterosexual African American (64%) and White (36%) female undergraduates from a large urban university in the southeastern United States. Participants completed measures of social demographics, sexual orientation, and sexual prejudice. Results showed that African American, relative to White, women endorsed more negative attitudes toward lesbians and gay men. Also, unlike White women, African American women reported more negative attitudes toward gay men than lesbians. Implications are discussed regarding differences in cultural contexts that exist between African American and White women.  相似文献

Smoking cessation failures are frequently thought to reflect poor top-down regulatory control over behavior. Previous studies have suggested that smoking cues occupy limited working memory resources, an effect that may contribute to difficulty achieving abstinence. Few studies have evaluated the effects of cognitive load on the ability to actively maintain information in the face of distracting smoking cues. For the present study, we adapted an fMRI probed recall task under low and high cognitive load with three distractor conditions: control, neutral images, or smoking-related images. Consistent with a limited-resource model of cue reactivity, we predicted that the performance of daily smokers (n = 17) would be most impaired when high load was paired with smoking distractors. The results demonstrated a main effect of load, with decreased accuracy under high, as compared to low, cognitive load. Surprisingly, an interaction revealed that the effect of load was weakest in the smoking cue distractor condition. Along with this behavioral effect, we observed significantly greater activation of the right inferior frontal gyrus (rIFG) in the low-load condition than in the high-load condition for trials containing smoking cue distractors. Furthermore, load-related changes in rIFG activation partially mediated the effects of load on task accuracy in the smoking-cue distractor condition. These findings are discussed in the context of prevailing cognitive and cue reactivity theories. These results suggest that high cognitive load does not necessarily make smokers more susceptible to interference from smoking-related stimuli, and that elevated load may even have a buffering effect in the presence of smoking cues under certain conditions.  相似文献

This research novelly explores how Future Time Perspective (FTP) plays a role in reflecting on goal failure and striving for future goals. Participants (N = 139) completed questionnaires assessing recent goal failure, procrastination, emotion regulation and FTP, then coded as either High or Low in FTP. Results support hypotheses that despite goal failure, those high in FTP procrastinated less, planned more and used more cognitive reappraisal strategies. Further, procrastination and cognitive reappraisal significantly predicted FTP scores. Thus, goal failure may be an essential part of learning how to achieve high self‐regulation goals. However, it may discourage some from trying again, particularly those low in FTP. Findings suggest the FTP may offer a strategy to aid attainment of important high self‐regulated, long‐term goals.  相似文献

Leisure-time physical activity (LTPA) represents an important factor contributing to the development and management of osteoporosis yet research linking LTPA with perceived health markers has been limited in this cohort. The purpose of this study was to test the relationship between LTPA and perceived health controlling for select demographic factors and chronic conditions in people living with osteoporosis. Population-health survey data from cycle 2.2 of the Canadian Community Health Survey were used in conjunction with linear multiple regression models. Participants were 1538 (n female = 1371) adults who reported living with osteoporosis. Demographic factors, chronic conditions, and more frequent participation in LTPA accounted for variance in diverse indices representing perceived health. LTPA was the only predictor to account for unique variance in each marker of perceived health. Overall, it would appear that increased use of LTPA as an adjunct to therapeutic interventions may be a viable aid to enhancing self-perceived health amongst Canadians living with osteoporosis.  相似文献

We describe the dilemmas we encountered in the informed consent process for an HIV prevention project targeting Black gay, bisexual, and non-gay identified young men. We highlight the complexities of applying informed parental consent procedures to sexual minority youth and identify some of the challenges that researchers who work with sexual minority youth face when they must balance the needs and rights of this population against the needs and rights accorded to parents by federal guidelines for protecting minor participants in research.  相似文献

The authors' goals in this article are to (a) describe a new task for the assessment of shifting attention between different affective stimuli, The Children's Attentional Shifting Task (CAST); (b) present the theoretical background for the development of the CAST; and (c) report initial information on the developmental appropriateness and validity of the CAST. The task was tested using a sample of kindergarten and 1st-grade children, 50% of whom had social and conduct problems. Preliminary analyses showed that the CAST was not subject to problems arising from fatigue or loss of interest. Moreover, children's ability to shift attention away from angry facial expressions was positively related to teachers' ratings of their ability to shift attention and parents' reports of children's emotion regulation. Shifting away from negative affect also predicted children's academic performance as reported by teachers.  相似文献

Eye Movement Desensitization and Reprocessing (EMDR) has been shown to be effective for treating posttraumatic stress disorder, but its efficacy as a stress management tool for normal individuals in highly stressful occupations has not been demonstrated. Sixty-two police officers were randomly assigned to either EMDR or a standard stress management program (SMP), each consisting of 6 hours of individualized contact. At completion, officers in the EMDR condition provided lower ratings on measures of PTSD symptoms, subjective distress, job stress, and anger; and higher marital satisfaction ratings than those in SMP. The effects of EMDR were maintained at the 6-month follow-up, indicating enduring gains from a relatively brief treatment regimen for this subclinical sample of officers who were experiencing some level of stress from their job.  相似文献

In Experiment 1, 2 groups of able-bodied children were exposed to both a complex single-tier virtual environment (VE) and a physical model of a different environment. For 1 group, the VE accurately modeled a real school, and for the other group the physical model did so. In transfer testing in the real school, orientation accuracy was greater in the group exposed to the VE of the real school. In Experiment 2, children with physical disabilities explored the VE model of the real school and were tested as in the 1st experiment. Measures of orientation accuracy and map-placing were significantly better in this group than in the guessing adult control group. The results illustrate the potential for VEs as useful spatial training media.  相似文献

A comprehensive home assessment was performed for 116 families whose twins were participants in a longitudinal study of early mental development. A large number of rating and observations made by a social worker during the home visit were condensed via factor analysis into four primary scores: adequacy of the home environment, maternal temperament, maternal cognitive skills, and maternal social-affect. The HOME scales of Caldwell (1978) were also completed, and all scores were combined with previously obtained measures of parental education and socioeconomic status. These scores were entered into a multiple regression analysis as predictors of off-spring mental development at 4 criterion ages: 6 months, 24 months, 3 years, and 6 years. The relationship was very weak at 6 months, but improved steadily over ages until reaching Rmult = .66 at 6 years. The four primary scores listed above plus father education all contributed significantly to the prediction of 6-year IQ scores, making it evident that home/family variables were substantially related to early mental development. However, a subsequent analysis using only parental education and SES as predictors yielded Rmult = .59. The qualitative features of home and mother thus appeared to augment a core linkage between parents and offspring representing intrinsic capabilities. The results are discussed in terms of both heritage and home environment as contributors to early mental development.  相似文献
