One hallmark of adolescent risk‐taking is that it typically occurs when adolescents are with peers. It has been hypothesized that the presence of peers primes a reward‐sensitive motivational state that overwhelms adolescents' immature capacity for inhibitory control. We examined this hypothesis using a rodent model. A sample of mice were raised in same‐sex triads and were tested for alcohol consumption either as juveniles or as adults, with half in each age group tested alone and half tested with their cagemates. The presence of ‘peers’ increased alcohol consumption among adolescent mice, but not adults. The peer effect on human adolescent reward‐seeking may reflect a hard‐wired, evolutionarily conserved process through which the presence of agemates increases individuals' sensitivity to potential rewards in their immediate environment. 相似文献

Several studies have linked rumination to substance use. However, only one study thus far has focused on the differential associations between the subtypes of rumination (brooding and reflection) and substance use. This previous study was cross-sectional in nature, so less is known about how these variables are related across time. To address this issue, the present three-wave longitudinal study investigated the cross-temporal associations between subtypes of rumination, alcohol consumption, drug consumption and substance use problems, using cross-lagged path analyses. In addition, the study investigated whether the cross-lagged paths of interest were moderated by gender. The sample consisted of 309 adolescents (62.1 % boys) between the ages of 13 to 20 years old (M age at T1?=?16.82 years, SD?=?1.32). Results indicated that substance use problems predicted increases in levels of brooding and reflection over time. These effects were moderated by gender so that substance use problems only predicted increases in levels of brooding and reflection in girls. In contrast to our expectations, higher levels of brooding predicted a decrease in alcohol consumption over time, and this effect was not moderated by gender. Cross-lagged analyses also showed that alcohol consumption predicted an increase in substance use problems. All results emerged independently of depressive symptoms. The findings of the present study add to the growing body of literature on the associations between rumination subtypes and substance use in adolescence, and highlight the importance of using longitudinal designs to address the issue of directionality. 相似文献

The ethics of managing obstetric patients in medical disasters poses ethical challenges that are unique in comparison to other disaster patients, because the medical needs of two patients--the pregnant patient and the fetal patient--must be considered. We provide an ethical framework for doing so. We base the framework on the justice-based prevention of exploitation of populations of patients, both obstetric and non-obstetric, in medical disasters. We use the concept of exploitation to identify a spectrum from ethically acceptable, to ethically challenging, to ethically unacceptable, management of obstetric patients in medical disasters. We also address the ethics of the care of obstetric and neonatal patients when the resources of a hospital are completely overwhelmed in a large-scale medical disaster. 相似文献

The fundamental need to belong: on the distinction between growth and deficit-reduction orientations
Lavigne GL Vallerand RJ Crevier-Braud L 《Personality & social psychology bulletin》2011,37(9):1185-1201
The need for belongingness (the universal need to form and maintain positive, stable interpersonal relationships) has led to much research over the past decade. Although such a need is universal, some qualitative differences exist in its orientation. Specifically, two belongingness need orientations are proposed: a growth orientation (a belongingness need directed toward interpersonal actualization) and a deficit-reduction orientation (a belongingness need directed toward interpersonal deficit reduction or repair). It is hypothesized that a deficit-reduction orientation to the need to belong is associated with lower levels of intrapersonal and interpersonal psychological functioning compared to a growth orientation. The results of a series of four studies supported the proposed hypotheses. Implications of the proposed model for future research on the need to belong are discussed. 相似文献

Problems with face recognition are frequent in older adults. However, the mechanisms involved have only been partially discovered. In particular, it is unknown to what extent these problems may be related to changes in configural face processing. Here, we investigated the face inversion effect (FIE) together with the ability to detect modifications in the vertical or horizontal second-order relations between facial features. We used a same/different unfamiliar face discrimination task with 33 young and 33 older adults. The results showed dissociations in the performances of older versus younger adults. There was a lack of inversion effect during the recognition of original faces by older adults. However, for modified faces, older adults showed a pattern of performance similar to that of young participants, with preserved FIE for vertically modified faces and no detectable FIE for horizontally modified faces. Most importantly, the detection of vertical modifications was preserved in older relative to young adults whereas the detection of horizontal modifications was markedly diminished. We conclude that age has dissociable effects on configural face-encoding processes, with a relative preservation of vertical compared to horizontal second-order relations processing. These results help to understand some divergent results in the literature and may explain the spared familiar face identification abilities in the daily lives of older adults. 相似文献

Under typical viewing conditions, human observers readily distinguish between materials such as silk, marmalade, or granite, an achievement of the visual system that is poorly understood. Recognizing transparent materials is especially challenging. Previous work on the perception of transparency has focused on objects composed of flat, infinitely thin filters. In the experiments reported here, we considered thick transparent objects, such as ice cubes, which are irregular in shape and can vary in refractive index. An important part of the visual evidence signaling the presence of such objects is distortions in the perceived shape of other objects in the scene. We propose a new class of visual cues derived from the distortion field induced by thick transparent objects, and we provide experimental evidence that cues arising from the distortion field predict both the successes and the failures of human perception in judging refractive indices. 相似文献
