Alcohol consumption among college students has become an increasing problem that requires attention from college administrators, staff, and researchers. Despite the physiological differences between men and women, college women are drinking at increasingly risky rates, placing them at increased risk for negative consequences. The current study tested a group motivational enhancement approach to the prevention of heavy drinking among 1st-year college women. Using a randomized design, the authors assigned participants either to a group that received a single-session motivational enhancement intervention to reduce risky drinking that focused partly on women's specific reasons for drinking (n = 126) or to an assessment-only control group (n = 94). Results indicated that, relative to the control group participants, intervention participants drank fewer drinks per week, drank fewer drinks at peak consumption events, and had fewer alcohol-related consequences over a 10-week follow-up. Further, the intervention, which targeted women's reasons for drinking, was more effective in reducing consumption for participants with high social and enhancement motivations for drinking. 相似文献

Brain-derived neurotrophic factor (BDNF) is one of the key molecules modulating brain plasticity. While low circulating levels of BDNF have been suggested to predispose to Alzheimer's disease, very little data are available on its association with cognitive function in general population. We evaluated the association between plasma BDNF levels and cognition in a representative population sample of ageing men and women. The subjects (n=1389) were participants of the Dose-Responses to Exercise Training (DR's EXTRA) Study and represent a random sample of Eastern Finnish people (684 men and 705 women), 57-79 years of age at baseline of the study. Plasma BDNF levels were measured by enzyme-linked immunosorbent assay (ELISA). Cognitive function was evaluated using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological test battery. Women had a higher mean (+/-SEM) plasma BDNF level than men (1721+/-55vs. 1495+/-54pg/ml, P<0.001). In women, 1 SD decrease in BDNF increased the risk for a low score in Naming Test by 53% (95% CI 1.21-1.92, P<0.001), in Mini-Mental State Examination by 63% (95% CI 1.21-2.20, P=0.001), in Word List Memory by 56% (95% CI 1.08-2.26, P=0.019), in Word List Recall by 50% (95% CI 1.10-2.05, P=0.010), in Word List Saving by 49% (95% CI 1.12-1.99, P=0.007), and in Word List Recognition by 64% (95% CI 1.19-2.25, P=0.002). Data were adjusted for age, education, depression, impaired glucose metabolism, cardiovascular disease, antihypertensive medication, lipid lowering medication, use of sex hormones, smoking, alcohol consumption, storing time of plasma in the freezer and platelet count. BDNF was not associated with cognition in men. Present data suggest that plasma BDNF is a biomarker of impaired memory and general cognitive function in ageing women. 相似文献

Previous empirical research has been unable to find a sufficient correlation between subjective well-being and per capita income, being hampered by limited longitudinal information and an inability to account for the predictions of competing theories. We bring new evidence to this question by exploiting a long and complete time-series from the Eurobarometer Survey, 1973–2002 allowing an examination of trends in life satisfaction across 15 European countries employing a modified version of Kendall’s Tau. Our results show that while current GDP growth does not affect trends in well-being, accelerations in GDP growth do. In addition, faster GDP growth and faster growth of government consumption than in neighbouring countries induces positive trends in life satisfaction. Our findings are consistent with the predictions of aspirations theory and the theory of reference group comparisons. 相似文献

Socio-cultural perspectives explain inconsistency in Chinese child-rearing research when imported methods and concepts are applied. We sought to elucidate child-rearing belief constructs relevant to Chinese contexts. Exploratory factor analysis identified items representing child-rearing concepts both imported and indigenous to Chinese culture and forming four dimensions: Training, Shame, Authoritative, and Autonomy. Data from parents of preschool-aged children in Hong Kong ( N = 228) and Taiwan ( N = 213) were subject to confirmatory factor and scale internal consistency analyses. Results support the conceptual and psychometric coherence of each subscale. Discussion of findings focuses on the benefits of culturally responsive methodology and the potential utility of the scales in child-rearing research with Chinese and other Confucian cultural populations. 相似文献

ABSTRACT— Perceived emotional support from close relationship partners in times of stress is a major predictor of well-being. However, recent research has suggested that, beyond emotional support, perceived support for achieving personal goals is also important for well-being. The present study extends such research by demonstrating that associations of perceived goal support with well-being differ depending on how people represent their goals and the general motivational context in which they pursue these goals. Among unmarried romantic partners, for whom the context of the relationship presumably is largely attainment oriented, perceived support for attainment-relevant (or promotion-focused ) goals independently predicted relationship and personal well-being, whereas perceived support for maintenance-relevant (or prevention-focused ) goals did not. In contrast, among married partners, for whom the context of the relationship presumably is both attainment and maintenance oriented, perceived support for both promotion-focused and prevention-focused goals independently predicted well-being. We discuss the implications for forecasting and improving well-being among married couples. 相似文献

Emerging research suggests that rumination increases risk for negative health outcomes. In the first experiment to investigate
cortisol responses during angry rumination, participants were provoked and induced to engage in self-focused rumination, provocation-focused
rumination, or distraction. Consistent with social threat theory, self-focused rumination maintained high levels of cortisol
following provocation, whereas provocation-focused rumination and distraction facilitated decreases in cortisol. However,
even within the provocation-focused rumination condition, adopting an emotionally reactive, self-immersed perspective was
associated with higher levels of cortisol as were thoughts about the self. Individual differences in displaced aggression
but not general aggression were also positively associated with cortisol levels in the provocation-focused condition. The
present findings shed light on rumination styles and cortisol responses in ways that may have long-term consequences for health
and well-being.

In the present study, we examined whether it is easier to judge when an object will pass one’s head if the object’s surface is textured. There are three reasons to suspect that this might be so: First, the additional (local) optic flow may help one judge the rate of expansion and the angular velocity more reliably. Second, local deformations related to the change in angle between the object and the observer could help track the object’s position along its path. Third, more reliable judgments of the object’s shape could help separate global expansion caused by changes in distance from expansion due to changes in the angle between the object and the observer. We can distinguish among these three reasons by comparing performance for textured and uniform spheres and disks. Moving objects were displayed for 0.5–0.7 sec. Subjects had to decide whether the object would pass them before or after a beep that was presented 1 sec after the object started moving. Subjects were not more precise with textured objects. When the disk rotated in order to compensate for the orientation-related contraction that its image would otherwise undergo during its motion, it appeared to arrive later, despite the fact that this strategy increases the global rate of expansion. We argue that this is because the expected deformation of the object’s image during its motion is considered when time to passage is judged. Therefore, the most important role for texture in everyday judgments of time to passage is probably that it helps one judge the object’s shape and thereby estimate how its image will deform as it moves. 相似文献

We tested the hypothesis that ruminating about a previous aggressive prime interacts with a subsequent minor frustration to augment aggression. Sixty participants watched a video showing a murder during a bank robbery (the aggressive prime). Those in the rumination condition were asked to write about the video for 20 min. In the no rumination condition, participants were given 20 min to complete an irrelevant task. Participants were then either frustrated or not frustrated. Our results supported the main hypothesis. Relative to the control condition, neither rumination nor frustration alone impacted aggression. Rumination, in combination with a minor frustration, however, increased the recommended prison sentence towards the targets. We discuss the implications of our findings. 相似文献
