High levels of trait hostility are associated with wide-ranging interpersonal deficits and heightened physiological response to social stressors. These deficits may be attributable in part to individual differences in the perception of social cues. The present study evaluated the ability to recognize facial emotion among 48 high hostile (HH) and 48 low hostile (LH) smokers and whether experimentally-manipulated acute nicotine deprivation moderated relations between hostility and facial emotion recognition. A computer program presented series of pictures of faces that morphed from a neutral emotion into increasing intensities of happiness, sadness, fear, or anger, and participants were asked to identify the emotion displayed as quickly as possible. Results indicated that HH smokers, relative to LH smokers, required a significantly greater intensity of emotion expression to recognize happiness. No differences were found for other emotions across HH and LH individuals, nor did nicotine deprivation moderate relations between hostility and emotion recognition. This is the first study to show that HH individuals are slower to recognize happy facial expressions and that this occurs regardless of recent tobacco abstinence. Difficulty recognizing happiness in others may impact the degree to which HH individuals are able to identify social approach signals and to receive social reinforcement. 相似文献

Modern ideals of female attractiveness include an extremely toned and fit appearance in addition to extreme thinness. Although viewing thin models has a negative effect on women's body image, research has not tested the effect of exposure to the ultra-fit physique separate from the thin-ideal. This randomized, posttest-only experiment tested the effects of the athletic aspect of the current ideal by exposing 138 undergraduate women to thin and athletic models, normal weight athletic models, or a control condition consisting of neutral objects. The study also tested the moderating effects of thin-ideal and athletic-ideal internalization. Exposure to thin ultra-fit models, but not normal weight ultra-fit models, produced an increase in body dissatisfaction and neither internalization variable moderated this effect. Findings suggest that interventions that focus on the benefits of fitness while challenging the desirability of thinness may offer promising results. 相似文献

An Institution for Change: Developing a Family Day Unit 总被引:1,自引:0,他引:1

This paper describes the theory and structure of a day unit designed to intervene in the systems of families who present with severe or multiple problems to agencies attempting to help them, but who are difficult to engage in a therapeutic pact and unresponsive to attempts at outpatient therapy. An analysis of these families is offered in terms of the relations between internal and external boundaries and difficulties in making transitions in the daily contexts of life. The principles of the unit are described in terms of the creation of an artificial extended family, the intensification of sequence and patterns of interaction, and the making and traversing of boundaries. Particular attention is paid to the function of agency interventions in family patterns and to redefining the relationship between family and agencies. 相似文献

Brain-derived neurotrophic factor (BDNF) plays a regulatory role in neuronal differentiation and synaptic plasticity and has been linked to glucose regulation and cognition. Associations among plasma BDNF, cognition, and insulin function were explored. Forty-one participants with impaired insulin function (IIF), ranging from insulin resistance to type 2 diabetes mellitus (T2DM), were matched with 41 healthy controls on gender, age, education, and IQ. Participants received complete medical, neurological, psychiatric, and neuropsychological evaluations. IIF individuals had significantly lower plasma BDNF levels than controls, particularly females, and higher BDNF levels were associated with poorer explicit memory in IIF females, suggesting that higher levels within this group may reflect the body’s efforts to respond to damage. After accounting for age, education, and HbA1c, BDNF significantly predicted 13.1–23.5% of the variance in explicit memory in IIF women. These findings suggest that BDNF elevations within diseased groups may not always be a marker of health. 相似文献

Stimulus overselectivity refers to the phenomenon whereby stimulus control over behavior is exerted only by a limited subset of the total number of stimuli present during discrimination learning. It often is displayed by individuals with autistic spectrum disorders or learning disabilities, but is not exclusive to those groups. The present studies investigated the impact of aging on stimulus control and overselectivity. Three age groups--18-22, 47-55, and 70-80 year olds-were studied in two experiments. All participants were trained on a simple discrimination task, randomly assigned to one of two conditions (either with or without a distractor task), and then tested for the emergence of overselectivity (Experiment 1). In Experiment 2 responding controlled by the overselected stimulus elements was reduced by introducing a verbal punisher. In subsequent tests, control of behavior by the previously underselected elements from Experiment 1 was enhanced across the two younger age groups but not the oldest group of participants. The results are discussed in relation to the attention-deficit and overshadowing accounts of overselectivity. 相似文献
