Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being.  相似文献

In this study, four children with autism were assessed to determine their preference choices for toothbrushes and toothpastes included during self-care skills teaching sessions. For two of the children, the presence of high-preference (HP) materials was associated with improved independent tooth brushing when compared to the presence of low-preference (LP) materials. There was no difference in independent tooth brushing between HP/LP conditions for the other two children. These findings suggest that preference and choice of materials alone can be a helpful instructional strategy for care providers serving children who have neurodevelopmental disorders and skill deficits.  相似文献

This study investigates economic locus of control (ELOC) in a Greek sample using Furnham's (1986) scale. In particular, it examines the association between ELOC and saving behavior and motives, attitudes toward state intervention in the economic field, and factors engendering confidence in economic matters. The main hypotheses predicted that internal ELOC should be associated with (a) desire for less state intervention; (b) confidence in factors under one's own control (knowing the other party in transactions, being well informed) more strongly than with other factors of economic trust, such as the state and the law; (c) more saving; and (d) that respondents with internal and external ELOC should be differentiated with respect to saving motives. Analysis was based on a sample of 135 participants from Athens. Principal components analysis of the Greek translation of Furnham's ELOC questionnaire gave results similar to those reported from England, yielding 4 factors interpretable as chance, internal, external/denial, and powerful others. The findings of the study include confirmation of all of the hypotheses.  相似文献

Despite fast technological developments in virtual reality (VR), methodologies and guidelines for evaluating the design of virtual environments (VEs) are lacking. The theory of perceptual opportunities (POs) has previously been proposed as a basis of such a design methodology. This paper presents an empirical study investigating the effect of representation of POs on users' behavior in VEs. The effects of both direction and movement of attractor on choice of objects in a simple VE were studied. Results showed that vertical static attractors were chosen least frequently. Furthermore, there was an effect of direction for static attractors in favor of the take-off direction. Implications for VE design in the framework of POs are discussed.  相似文献

With a ‘split ad’, information is presented as two distinct parts, such as when two short commercials for a given brand are separated by other television content. Two studies are presented in this paper which demonstrate the advantages of an emerging form of the split ad strategy, which is termed the ‘hybrid split ad’ technique. Using this approach, a message typically begins in a traditional medium and then concludes at a website. In Experiment 1, the hybrid split ad technique is shown to enhance attitudes towards an advertised product by increasing the perceived importance of favourable attributes provided at the website. Experiment 2 replicates this finding and also addresses an issue of managerial importance, namely, how to motivate consumers to pursue the second (web‐based) portion of the ad. Offering consumers an incentive at the website is useful in this regard, provided that the incentive is small enough not to undermine the positive effects of the hybrid split ad.  相似文献

Older persons constitute an increasingly large population with significant mental health challenges. The authors review outcome research for both diagnosable conditions and late‐life transitions as a basis for evidence‐based practice with this population. Implications for clinical practice in professional counseling, counselor education and supervision, and research are considered.  相似文献

This study examined the associations between infant and childhood growth and severe personality disorders. Among 4,689 men and 4,200 women of the Helsinki Birth Cohort Study 1934-1944, 81 men and 68 women had been hospitalized with an ICD (-8, -9, -10) diagnosis of personality disorder in adulthood. Among men, slower gain in BMI between birth and 6 months, faster gain in weight and BMI between 6 months and 1 year, and slower gains in them between 7 and 11 years of age predicted an increased risk of hospitalization for personality disorders. Thinness at 6 months and again at 11 years also showed significant association with personality disorders among men. Among women, slower gain in height between 2 and 7 years predicted hospitalization for personality disorders. Our findings show the importance of early growth as a vulnerability factor of personality disorders severe enough to justify hospitalization.  相似文献

The current study used the partially-baited radial-arm maze paradigm to study the effects of a single-treatment high-dose exposure ('binge') to MDMA (± 3,4-methylenedioxymethaphemtamine or 'Ecstasy') on memory task acquisition. Sprague-Dawley rats were administered a binge dose (4 × 10 mg/kg) of MDMA and their ability to subsequently acquire the radial-arm maze task was compared against saline controls. The MDMA-treated rats were significantly slower to learn the task and made more reference memory errors than the controls. Working memory function was found to be relatively unimpaired. Following a reversal of task rules the MDMA-treated rats were again significantly slower to acquire the appropriate rule despite having eventually achieved a similar level of overall performance as control rats. However evidence of drug tolerance was found when all rats were challenged with an acute low dose of MDMA (1 × 4.0 mg/kg) because the binge MDMA rats were relatively less impaired. Therefore, although binge treated MDMA rats were able to achieve very accurate performance equivalent to the controls they took significantly longer to do this and were less able to adapt their behavior to a change in task rules. In addition the binge treated MDMA rats displayed tolerance to acute MDMA exposure. These findings are consistent with the possibility that human Ecstasy users may show deficits in acquiring information and may experience deficits in cognitive flexibility as well as developing tolerance to the drug with repeated exposure.  相似文献

Previous research indicates that pairing pictures with associated words when teaching sight-word reading may hinder acquisition (e.g., Didden, Prinsen, & Sigafoos, 2000; Singh & Solman, 1990; Solman & Singh, 1992). The purpose of the current study was to determine whether this phenomenon was due to a previously learned association between the spoken word and picture (i.e., blocking) or due to the mere presence of a picture as an extrastimulus prompt (i.e., overshadowing). Three participants were taught to recognize words that were presented alone or paired with pictures that the participants either could or could not identify prior to training. All participants learned the words more quickly when they were presented alone rather than with pictures, regardless of their prior learning history with respect to pictures representing the words. This finding is consistent with the phenomenon of overshadowing. Nonetheless, consistent with blocking, all participants also acquired the words presented alone more quickly if they could not identify the associated pictures prior to training. Together, these findings have important implications for using prompts when teaching skills to individuals with developmental disabilities.  相似文献
