Are Traditional Gender Role Attitudes Associated With Risky Sexual Behavior and Condom-related Beliefs? 总被引:3,自引:0,他引:3

Traditional gender role attitudes, which emphasize an unequal distribution of power in the family and stereotypical norms about masculinity, may be associated with unsafe sexual behavior and beliefs in young men and women. This study was designed to examine associations between gender role attitudes including gender-based family role attitudes and masculinity ideology, sexual behaviors, and condom-related beliefs in a sample of sexually active college students (N = 154). Family role attitudes were related to risky condom-related beliefs but not to risky sexual behavior. Masculinity ideology was related to both sexual behaviors and condom-related beliefs but, in some cases, in a direction opposite to that predicted. These unexpected findings and the utility of examining masculinity ideology among women are discussed.An earlier version of this paper was presented at the 2002 Biennial Meeting of the Society for Research on Adolescence, New Orleans, Louisiana. 相似文献

The study aimed to address a significant gap in the literature on inhibition impairments in OCD, by concurrently studying facilitation and inhibition processes and the effect of threat on these twin mechanisms. Participants were 20 persons with symptomatic OCD, 11 with remitted OCD, 20 with panic disorder and 20 normal control participants. Participants were required to respond to words that were either neutral or personally threatening, which during an immediately preceding trail, were responded to as targets (facilitation) or inhibited as non-targets (inhibition). OCD participants displayed greater facilitation and reduced inhibition, differences that were related to their diagnostic status but unrelated to symptomatic status. Threat had no effect on facilitation, but exacerbated inhibition problems in the symptomatic OCD and panic groups. This research suggests that underlying differences in both facilitation and inhibition, combined with influences of activated threat-schema on inhibition may play a role in the development and maintenance of OCD. 相似文献

What are the factors that influence everyday attributions of cause and blame? The current studies focus on sequences of events that lead to adverse outcomes, and examine people's cause and blame ratings for key events in these sequences. Experiment 1 manipulated the intentional status of candidate causes and their location in a causal chain. Participants rated intentional actions as more causal, and more blameworthy, than unintentional actions or physical events. There was also an overall effect of location, with later events assigned higher ratings than earlier events. Experiment 2 manipulated both intentionality and foreseeability. The preference for intentional actions was replicated, and there was a strong influence of foreseeability: actions were rated as more causal and more blameworthy when they were highly foreseeable. These findings are interpreted within two prominent theories of blame, [Shaver, K. G. (1985). The attribution of blame: Causality, responsibility, and blameworthiness. New York: Springer-Verlag] and [Alicke, M. D. (2000). Culpable control and the psychology of blame. Psychological Bulletin, 126, 556-574]. Overall, it is argued that the data are more consistent with Alicke's model of culpable control. 相似文献

Over the past 30 years researchers have learned a great deal about the development of object processing in infancy. In contrast, little is understood about the neural mechanisms that underlie this capacity, in large part because there are few techniques available to measure brain functioning in human infants. The present research examined the extent to which near-infrared spectroscopy (NIRS), an optical imaging technique, could be used to assess the relation between object processing and brain functioning. Infants aged 6.5 months were presented with an occlusion event involving objects that differed on many feature dimensions (multi-featural change), differed on shape only (shape change) or color only (color change), or did not differ (control). NIRS data were collected in the occipital and inferior temporal cortex. In the occipital cortex, a significant increase in oxyhemoglobin (HbO(2)) was observed in response to all four events and these responses did not differ significantly from each other. In the inferior temporal cortex, a significant increase in HbO(2 )was observed in the multi-featural and the shape change condition but not in the control condition. An increase was also observed in the color change condition but this increase did not differ significantly from baseline nor did it differ significantly from the response obtained in the control condition. These data were discussed in terms of (a) what they suggest about the neural basis of feature processing in infants and (b) the viability of using NIRS to study brain-behavior relations in infants. 相似文献

The purpose of this study was to investigate the relationship between the use of condoms and other contraceptive methods and religiosity/spirituality among youths of a low socioeconomic level in Porto Alegre. 1013 youths, between 12-24 years of age participated, responding to a personal questionnaire containing 109 items. Results show that 53.5% of these youths had already had their first sexual encounter, 55% of which had this experience before the age of 15. The majority (42.8%) claimed to be Catholic, and 26.7% said they believe in God, but were not religious. There appeared no significant difference in the use of condoms in relation to the level of religiosity, however, men used this method more than women to avoid AIDS and as a contraceptive. Women used other contraceptive methods more frequently, and there were no cases of exclusive use of methods permitted by the major religions (natural methods). This study revealed a high level of condom use (more than 80%) among both religious and non-religious youths. 相似文献

This article compares several methods for performing robust principal component analysis, two of which have not been considered in previous articles. The criterion here, unlike that of extant articles aimed at comparing methods, is how well a method maximizes a robust version of the generalized variance of the projected data. This is in contrast to maximizing some measure of scatter associated with the marginal distributions of the projected scores, which does not take into account the overall structure of the projected data. Included are comparisons in which distributions are not elliptically symmetric. One of the new methods simply removes outliers using a projection-type multivariate outlier detection method that has been found to perform well relative to other outlier detection methods that have been proposed. The other new method belongs to the class of projection pursuit techniques and differs from other projection pursuit methods in terms of the function it tries to maximize. The comparisons include the method derived by Maronna (2005), the spherical method derived by Locantore et al. (1999), as well as a method proposed by Hubert, Rousseeuw, and Vanden Branden (2005). From the perspective used, the method by Hubert et al. (2005), the spherical method, and one of the new methods dominate the method derived by Maronna. 相似文献

This study examines African American faith based leaders’ attitudes and beliefs about providing HIV prevention education and
services to adolescents. Using a convenience sample, we identified priority adolescent health issues, attitudes about abstinence
messages, and willingness to provide and participate in HIV prevention. Leaders identified drugs, gangs, alcohol, sex, and
pregnancy as priority health issues affecting youth in their institutions. Leaders’ strongly preferred to emphasize abstinence
messages. Although leaders were willing to provide youth with health education, they were not willing to discuss specific
behaviors associated with HIV transmission. African American churches provide a venue to reach African American youth; however,
there are limitations to relying on faith-based HIV prevention services. HIV prevention education should continue to be supplemented
via parents, schools, and public health agencies.

Exposure to thin-ideal media has adverse effects on the body satisfaction of women with higher levels of body image disturbance.
In a study involving 109 UCLA female undergraduates, we examined the effectiveness of an intervention that was based on downward
social comparison theory and the selection of alternative comparison dimensions. All participants had higher levels of body
dissatisfaction and viewed pictures of fashion models; the intervention group compared downward with the models on non-appearance
dimensions in writing, whereas the control group described the models in writing. We hypothesized that the intervention group
would experience more positive shifts in body and weight satisfaction, anxiety about appearance, and desire to lose weight
than would the control group. The results supported our hypotheses. 相似文献

Adults described and dated two kinds of personal remembrances: a fragment—a memory moment that is largely bereft of context—and an episodic, personal event memory—a narrative that consists of a number of related events. In Experiment 1 subjects reported memories from when they were 0–8 years of age and in Experiment 2, from when they were 0–16 years of age. Fragments were judged to be older than event memories, especially in Experiment 2 where the estimated ages of most fragments were from 0 to 8 years and of most episodic memories, from 8 to 16 years. Ratings of various features of the two kinds of memories also differed. We conclude that isolated memory moments possess validity and that although they are most likely to arise when the autobiographical memory system is not fully developed, they can also originate during a time when it is.
