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

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

We explored whether rhesus monkeys (Macaca mulatta) share one important feature of human essentialist reasoning: the capacity to track category membership across radical featural transformations. Specifically, we examined whether monkeys – like children ( Keil, 1989 ) – expect a transformed object to have the internal properties of its original category. In two experiments, monkeys watched as an experimenter visually transformed a familiar fruit (e.g. apple) into a new kind of fruit (e.g. coconut) either by placing a fruit exterior over the original, or by removing an exterior shell and revealing the inside kind of fruit. The experimenter then pretended to place an inside piece of the transformed fruit into a box which the monkey was allowed to search. Results indicated that monkeys searched the box longer when they found a piece of fruit inconsistent with the inside kind, suggesting that the monkeys expected that the inside of the transformed fruit would taste like the innermost kind they saw. These results suggest that monkeys may share at least one aspect of psychological essentialism: They maintain category‐specific expectations about an object’s internal properties even when that object’s external properties change. These results therefore suggest that some essentialist expectations may emerge in the absence of language, and thus raise the possibility that such tendencies may emerge earlier in human development than has previously been considered. 相似文献

Forming an implementation intention (‘If I encounter situation X, then I'll perform behaviour Y!’) is thought to increase the likelihood that the person will detect a good opportunity to act. Experiment 1 found support for this hypothesis in a novel context where detection of the specified cue was very difficult. Experiments 2 and 3 extended existing paradigms to test whether this improved cue detection has costs in terms of increased false positives and/or slower responses to ambiguous stimuli. This hypothesis was not supported. Forming an implementation intention led to more accurate (Experiment 2) and faster (Experiment 3) responses to the specified cue without compromising responses to non‐relevant, or ambiguous, stimuli. Overall, the findings suggest that forming an implementation intention is an effective self‐regulatory tool because the specified cues are discriminated swiftly and with precision.
