The current longitudinal study explores the relationship between adolescent television use at time 1 and sexual experience
and relationship status (i.e., committed/romantic versus casual) 1 year later. The sample (N = 824) comprised youth aged 14–18. Multinomial logistic regressions predicting group membership from television exposure
variables were conducted controlling for socio-demographic characteristics and prior sexual behavior. Results indicate that
sexually inexperienced youth watched more television overall than sexually experienced youth, but less adult, premium and
music television on cable networks. Premium cable exposure predicted group membership among sexually active youth. Youth who
watched more premium cable at time 1 were more likely to be in casual relationship at last intercourse than a committed one.
A more complete understanding of media effects on adolescent sexual relationships can help guide policy development, media
education/literacy efforts, and contribute to the design of interventions to reduce the negative consequences associated with
adolescent sexual behavior. 相似文献

Although the amnestic effects of alcohol in humans are well known, its effects on emotional memory are unclear. In this study, using a randomized double-blind placebo-controlled design, we examine narrative emotional episodic memory in healthy human female volunteers (n = 32) who received either a single dose of alcohol (0.6 g/kg), or a placebo and then viewed neutral story elements presented in either a neutral or emotional context. Memory was tested for gist and detail of the neutral elements 3 days later in a surprise recognition test. Since alcohol modulates GABAergic neurotransmission and may exert its effects on emotion through the limbic system, we predicted that acute alcohol treatment would reduce the expected emotional memory-advantage for gist, leaving detail memory relatively unaffected. Furthermore, given previous findings showing that ‘primacy’ memory is enhanced by physiological arousal, we predicted that reduced arousal produced by alcohol would have the opposite effect and impair primacy memory relative to the middle or ‘recency’ sections of the narrative. Emotional arousal was expected to oppose this effect, so impaired primacy memory following alcohol was only expected in the neutral version of the narrative. Although there was a main effect of story phase (though not of story version), contrary to expectations, alcohol impaired primacy memory for emotionally encoded neutral material. The results suggest that under certain circumstances emotional context or physiological arousal make memories labile and susceptible to disruption through pharmacological manipulation during encoding. 相似文献

Novice drivers (teen drivers with their solo license for 6 months or less) are at a greatly inflated risk of crashing. Post hoc analyses of police accident reports indicate that novice drivers fail to anticipate hazards, manage their speed, and maintain attention. These skills are much too broadly defined to be of much help in training. Recently, however, driving simulators have been used to identify those skills which differentiate the novice drivers from older, more experienced drivers in the areas of hazard anticipation and speed management. Below, we report an experiment on a driving simulator which compares novice and experienced drivers’ performance in the third area believed to contribute especially heavily to crashes among novice drivers: attention to the forward roadway. The results indicate that novice drivers are much more willing to glance for long periods of time inside the vehicle than are experienced drivers. Interestingly, the results also indicate that both novice and experienced drivers spend equal amounts of time glancing at tasks external to the vehicle and in the periphery. Moreover, just as a program has been designed to train the scanning skills that clearly differentiate novice from experienced drivers, one might hope that a training program could be designed to improve the attention maintenance skills of novice drivers. We report on the initial piloting of just such a training program. Finally, we address a question that has long been debated in the literature: Do the results from driving simulators generalize to the real world? We argue that in the case of hazard anticipation, speed management, and attention maintenance the answer is yes. 相似文献

A feminist phenomenological analysis of voice, rooted in both the feminist understanding of the role of voice in identity,
agency, and the creation of meaning, and the phenomenological thematization and theorization of phenomenal, lived experience,
leads to a deeper understanding of the importance of the materiality of the voices with which we speak, and their role in
both subjective and intersubjective experience. Starting from an analysis of the intertwined associations and imageries of
the feminine, voice, and embodiment, I discuss the denaturalization and abstraction of voice in standard narratives of voice
and voice metaphorization, and the corresponding forgetting of the living, bodily voice. In looking to recall a re-naturalized
and immanent corporeality and retrieve the material voice through an account of embodied vocality, I consider examples of
the power and immediacy of the corporeal voice in the female operatic voice, and in contrast, the compromised agency and attenuated
(inter)subjectivity which attends the impaired or lost physical voice. These vocal counterpoints of presence and absence are
often separated by corporeal disturbance or limitation, underscoring the importance of corporeality and the material voice
as intermediary between the individual and the social world. This sets the contours of a phenomenology of embodied voice and
vocality, holding implications for accounts of identity and intersubjectivity, gendered vocality and expressive agency, and
an intercorporeality mediated by the living material voice. 相似文献

A social indicators community project was conducted in 2007 to monitor living standards and quality of life in Rhini, a low-income
suburb of Grahamstown, Makana Municipality, South Africa. Since 1994, under democratic rule, considerable progress has been
made in service delivery to the formerly disadvantaged in South African society in terms of access to housing, infrastructure,
and a social safety net to mitigate the high rate of unemployment. A representative cross-sectional household study (n 1020)
conducted in 2007 in Rhini found that a positive assessment of the household’s situation and personal life satisfaction did
not reflect better living conditions. Lack of income and employment opportunities appeared to dilute gains from higher living
standards. The project also inquired into attitudes to place names and a proposed name change for the city under discussion
at the time of the survey. It is argued that a place name with which one can identify may be as important as service delivery
to enhance community satisfaction and overall quality of life. Dissatisfied residents who had limited access to services and
expressed less civic pride were more likely than others to opt for a proposed name change for the city of Grahamstown that
would better reflect the country’s new identity and multicultural heritage. It is concluded that a useful pursuit for community
quality-of-life studies in countries undergoing social transformation will be to inquire into the complex combination of factors
that drive perceptions of material and symbolic progress. 相似文献

CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol. 相似文献

Although previous research demonstrated that networks matter for health-related outcomes, few studies have investigated the possibility that network effects may differ between women and men. In a multivariate regression analysis of a US sample of 548 hurricane victims, we ask whether effects of network composition, density, and size affect perceived adequacy of social support and depressive symptoms more strongly among women than among men. We find evidence for these moderating effects, for direct effects of density on support adequacy and size on depressive symptoms. Our examination of indirect effects of network structure on depressive symptoms, in the pathway through perceived adequacy of social support, suggests that gender may exert more substantial moderating effects than previous health studies suggest. 相似文献

Do 18-month-olds understand that an agent's false belief can be corrected by an appropriate, though not an inappropriate, communication? In Experiment 1, infants watched a series of events involving two agents, a ball, and two containers: a box and a cup. To start, agent1 played with the ball and then hid it in the box, while agent2 looked on. Next, in agent1's absence, agent2 moved the ball from the box to the cup. When agent1 returned, agent2 told her "The ball is in the cup!" (informative-intervention condition) or "I like the cup!" (uninformative-intervention condition). During test, agent1 reached for either the box (box event) or the cup (cup event). In the informative-intervention condition, infants who saw the box event looked reliably longer than those who saw the cup event; in the uninformative-intervention condition, the reverse pattern was found. These results suggest that infants expected agent1's false belief about the ball's location to be corrected when she was told "The ball is in the cup!", but not "I like the cup!". In Experiment 2, agent2 simply pointed to the ball's new location, and infants again expected agent1's false belief to be corrected. These and control results provide additional evidence that infants in the second year of life can attribute false beliefs to agents. In addition, the results suggest that by 18 months of age infants expect agents' false beliefs to be corrected by relevant communications involving words or gestures. 相似文献

Previous research has shown that suspects in real-life interviews do not display stereotypical signs of nervous behaviours, even though they may be experiencing high detection anxiety. We hypothesised that these suspects may have experienced cognitive load when lying and that this cognitive load reduced their tonic arousal, which suppressed signs of nervousness. We conducted two experiments to test this hypothesis. Tonic electrodermal arousal and blink rate were examined during task-induced (Experiment 1) and deception-induced cognitive load (Experiment 2). Both increased cognitive difficulty and deception resulted in decreased tonic arousal and blinking. This demonstrated for the first time that when lying results in heightened levels of cognitive load, signs of nervousness are decreased. We discuss implications for detecting deception and more wide-ranging phenomena related to emotional behaviour. 相似文献
