We investigated women's facial attractiveness and body shape as a function of menstrual cycle phase, with the expectation from previous research that both would be enhanced during the high fertile phase. To control for the effects of women's daily behaviors on their appearance and waistline, we visited 37 normally cycling women twice in their dorm, where we photographed and measured them at low and high fertile days of their cycle immediately upon their waking. Seventy-four judges from a separate institution chose, for each woman, the picture they thought was more attractive. We analyzed a subset of 20 women who, by forward counting, had a High Fertility visit between Days 10-13 and a Low Fertility visit between Days 20-23; and we also analyzed a subsample of 17 women who, by reverse counting, had a High Fertility visit on the days leading to ovulation and a Low Fertility visit one week after ovulation. In neither set of analyses were women's waist- to-hip ratios lower nearer ovulation, and in neither set were women's high fertile pictures chosen at an above-chance rate by either male or female judges. We did not find evidence that facial attractiveness and waist-to-hip ratio are reliable physical cues of ovulatory status.  相似文献

The goal of the current study is to examine the relationship amongst social support, stress, and depressive symptoms within a transactional and diathesis-stress framework using a multi-wave, longitudinal design. At the initial assessment, adolescents (n = 258) completed self-report measures assessing social support (peer, classmate, parent, and total), dependent interpersonal stress, anxious symptoms, and depressive symptoms. Additionally, participants reported stress and symptomology in each of the four waves spanning six months. Results of time-lagged, idiographic, multilevel modeling indicated that stress mediated the relationship between lower parental, classmate, and total social support and subsequent depressive, but not anxious, symptoms. In contrast, lower levels of peer support were not associated with higher levels of stress and subsequent depressive symptoms. Additionally, only classmate support deficits significantly moderated the relationship between stress and depressive symptoms. Overall, the results suggest that deficits in parental and classmate support may play a greater role in contributing to adolescent depression as compared to deficits in peer support.  相似文献

Objectives

Health promotion agencies advocate use of mountain climbing goals to encourage regular stair climbing, a current public health target. This paper tests effects of a mountain climbing campaign on objective measures of stair use for the first time.

Design

Field interview and quasi-experimental, interrupted time-series study.

Method

In field interviews, a convenience sample (n = 1350) responded to questions about different goals, i.e., heights of climb, to encourage stair use in buildings. Subsequently, a point-of-choice intervention with the main message ‘Take the stairs to the top of this building once a day and in a year, you would have climbed Mount Everest almost twice’ was tested in a 12-floor worksite. A no-message baseline was followed by installation of the intervention.

Results

Stair ascent (n = 62,716) and descent (n = 61,218) at the ground floor was measured with automated counters at baseline (11 days) and during the intervention (18 days). The majority of interviewees (60%) chose a message based on climbing Mt. Everest as the most motivating, with only 5% of interviewees not motivated by any climbing goal. Nonetheless, the subsequent intervention using the mountain climbing goal had no effect on stair climbing (OR = 0.96). As the campaign specifically targeted stair ascent, it failed to influence the behaviour with the greater public health dividend.

Conclusion

The discrepancy between pre-testing and the campaign may reflect the fact that performance goals can only be achieved at the end of the task and may not be continually rewarded during accumulation of behaviour towards the goal.  相似文献

The present study explored African American (n = 16) and European American (n = 19) college women's ideal body size perceptions for their own and the other ethnic group along with reasons behind their selections. Respondents completed an ethnically-neutral figure rating scale and then participated in ethnically-homogenous focus groups. European Americans mostly preferred a curvy-thin or athletic ideal body while most African American students resisted notions of a singular ideal body. European Americans suggested that African Americans’ larger ideal body sizes were based on greater body acceptance and the preferences of African American men. African Americans used extreme terms when discussing their perceptions of European Americans’ thin idealization, celebrity role models, and weight management behaviors. African Americans’ perceptions of European Americans’ body dissatisfaction were also attributed to the frequent fat talk they engaged in. Implications for promoting the psychosocial well-being of ethnically-diverse emerging adult females attending college are discussed.  相似文献

This study compared person risk factors among the following groups of low-income, African American adults in an urban, public hospital: (a) suicide attempters and nonattempters, (b) male and female attempters, and (c) all 4 groups (50 female attempters, 50 female nonattempters, 50 male attempters, and 50 male nonattempters). Participants completed psychological distress, aggression, substance use, cognitive processes, religiosity/spirituality, and ethnic identity measures. Compared with nonattempters, attempters reported more psychological distress, aggression, substance use, and maladaptive coping strategies; less religiosity/spirituality; and lower levels of ethnic identity. Male attempters endorsed more substance use than female attempters. No person risk factors differentiated among the 4 groups. Assessment of person risk factors and implementation of commensurate culturally competent interventions are recommended.  相似文献

Tracking exceptional human capital over two decades   总被引:1,自引:0,他引:1  
Talent-search participants (286 males, 94 females) scoring in the top 0.01% on cognitive-ability measures were identified before age 13 and tracked over 20 years. Their creative, occupational, and life accomplishments are compared with those of graduate students (299 males, 287 females) enrolled in top-ranked U.S. mathematics, engineering, and physical science programs in 1992 and tracked over 10 years. By their mid-30s, the two groups achieved comparable and exceptional success (e.g., securing top tenure-track positions) and reported high and commensurate career and life satisfaction. College entrance exams administered to intellectually precocious youth uncover extraordinary potential for careers requiring creativity and scientific and technological innovation in the information age.  相似文献

Many evaluations of cognitive models rely on data that have been averaged or aggregated across all experimental subjects, and so fail to consider the possibility of important individual differences between subjects. Other evaluations are done at the single-subject level, and so fail to benefit from the reduction of noise that data averaging or aggregation potentially provides. To overcome these weaknesses, we have developed a general approach to modeling individual differences using families of cognitive models in which different groups of subjects are identified as having different psychological behavior. Separate models with separate parameterizations are applied to each group of subjects, and Bayesian model selection is used to determine the appropriate number of groups. We evaluate this individual differences approach in a simulation study and show that it is superior in terms of the key modeling goals of prediction and understanding. We also provide two practical demonstrations of the approach, one using the ALCOVE model of category learning with data from four previously analyzed category learning experiments, the other using multidimensional scaling representational models with previously analyzed similarity data for colors. In both demonstrations, meaningful individual differences are found and the psychological models are able to account for this variation through interpretable differences in parameterization. The results highlight the potential of extending cognitive models to consider individual differences.  相似文献
