Differences in motives for condom use and their implications for understanding frequency of use were investigated in a random, biracial (Black, White) sample of heterosexuals, aged 17 to 25 years (n = 902). Results indicated that sexually active young adults-regardless of race, age, gender, or relationship status-were more likely to use condoms to prevent pregnancy than to prevent disease. Reasons for use mediated the effects of relationship status on condom use per se and moderated the effects of attitudinal and perceptual variables on condom use. Finally, comparisons among condom users motivated by different prevention goals and nonusers (n = 388) revealed that differences among user subgroups were nearly as numerous and, in some cases, more robust than differences between users and nonusers. These findings indicate that condom users comprise distinct subgroups, defined in part by their underlying motives for use, and highlight important conceptual and empirical reasons to distinguish among them. 相似文献

Fear conditioning represents the process by which a neutral stimulus comes to evoke fear following its repeated pairing with an aversive stimulus. Although fear conditioning has long been considered a central pathogenic mechanism in anxiety disorders, studies employing lab-based conditioning paradigms provide inconsistent support for this idea. A quantitative review of 20 such studies, representing fear-learning scores for 453 anxiety patients and 455 healthy controls, was conducted to verify the aggregated result of this literature and to assess the moderating influences of study characteristics. Results point to modest increases in both acquisition of fear learning and conditioned responding during extinction among anxiety patients. Importantly, these patient-control differences are not apparent when looking at discrimination studies alone and primarily emerge from studies employing simple, single-cue paradigms where only danger cues are presented and no inhibition of fear to safety cues is required. 相似文献

The current study utilizes in-depth interviews with inner city African-American and Latino adolescents to understand how they negotiate initial substance use. We applied the social norms approach to explore the role of peers, family, and neighborhood on adolescents’ initial substance use. Utilizing data from 36 interview participants, our analysis revealed that extended family members were pivotal in providing adolescents with their initial alcohol; however, female adolescents were more likely than male adolescents to acquire marijuana from their male peers, for free. Understanding situational contexts underlying initial substance use is imperative for future interventions with this population. 相似文献

Recent results from our laboratory showed that, in fixed-target parallel search tasks, reaction times increase in a logarithmic fashion with set size, and the slope of this logarithmic function is modulated by lure-target similarity. These results were interpreted as being consistent with a processing architecture where early vision (stage one) processes elements in the display in exhaustive fashion with unlimited capacity and with a limitation in resolution. Here, we evaluate the contribution of crowding to our recent logarithmic search slope findings, considering the possibility that peripheral pooling of features (as observed in crowding) may be responsible for logarithmic efficiency. Factors known to affect the strength of crowding were varied, specifically: item spacing and similarity. The results from three experiments converge on the same pattern of results: reaction times increased logarithmically with set size and were modulated by lure-target similarity even when crowding was minimized within displays through an inter-item spacing manipulation. Furthermore, we found logarithmic search efficiencies were overall improved in displays where crowding was minimized compared to displays where crowding was possible. The findings from these three experiments suggest logarithmic efficiency in efficient search is not the result peripheral pooling of features. That said, the presence of crowding does tend to reduce search efficiency, even in “pop-out” search situations. 相似文献

Cognitive theories suggest that social anxiety is maintained, in part, by an attentional bias toward threat. Recent research shows that a single-session of attention modification training (AMP) reduces attention bias and vulnerability to a social stressor (Amir, Weber, Beard, Bomyea, &; Taylor, 2008). In addition, exercise may augment the effects of attention training by its direct effects on attentional control and inhibition, thereby allowing participants receiving the AMP to more effectively disengage attention from the threatening cues and shift attention to the neutral cues. We attempted to replicate and extend previous findings by randomizing participants (N = 112) to a single-session of: a) Exercise + attention training (EX + AMP); b) Rest + attention training (REST + AMP); c) Exercise + attention control condition (EX + ACC); or d) Rest + attention control condition (REST + ACC) prior to completing a public speaking challenge. We used identical assessment and training procedures to those employed by Amir et al. (2008). Results showed there was no effect of attention training on attention bias or anxiety reactivity to the speech challenge and no interactive effects of attention training and exercise on attention bias or anxiety reactivity to the speech challenge. The failure to replicate previous findings is discussed. 相似文献

Parents of young children with type 1 diabetes (T1DM) maintain full responsibility for their child’s daily diabetes self-care
and thus may be vulnerable to experiencing parenting stress. This study examined several psychological correlates of pediatric
parenting stress in parents of young children with T1DM. Parents of 39 young children with T1DM (ages 2–7 years) completed
measures of pediatric parenting stress, mealtime behavior problems, depressive symptoms, and fear of hypoglycemia. For parents
of young children, higher stress frequency and difficulty were associated with higher parental depressive symptoms and fear.
Regression analyses identified that 58% of the variance in stress frequency was associated with parental depressive symptoms.
For stress difficulty, 68% of the variance was associated with parental depressive symptoms and fear. Pediatric parenting
stress is common in parents of young children with T1DM. Stress and the psychological correlates measured in this study are
amenable to intervention and should be regularly assessed in parents of young children with T1DM. 相似文献
