The current study presents a method for assessing the relative effects of attention and escape on noncompliance in preschoolers. Attention and escape conditions were alternated in a multielement design, and a contingency reversal procedure, in which one test condition served as a control for the other, was used to demonstrate control. For all 3 participants, noncompliance was maintained, at least in part, by social attention. Functional analyses of noncompliance such as the one described here may be valuable for developing function‐based treatments.  相似文献

This case series aims to examine the preliminary efficacy, acceptability and feasibility of Family-Based Treatment to promote weight restoration in young adults with anorexia nervosa. Four young adults with sub/threshold anorexia nervosa were provided 11–20 sessions of Family-Based Treatment for young adults with pre-, post- and follow-up assessments. At post- and follow-up, 3/4 participants were in the normal weight range, 3/4 were in the non-clinical range on the Eating Disorders Examination and reported being not/mildly depressed. At post-treatment, 2/4 were in the good psychosocial functioning range and by follow-up, 3/4 were in this range. These results suggest that Family-Based Treatment for young adults with anorexia nervosa is a promising treatment.  相似文献

Self-assessed health in four items of the Health Related Quality of Life Scale, overall health, physical health, mental health, and activity limitation, and perceived life satisfaction in six domains of the Brief Multidimensional Students’ Life Satisfaction Scale, overall life, family life, friendships, school experience, myself, and where I live were examined among 4,502 Chinese adolescent secondary school students in Hong Kong. Relative to the US adolescents in Youth Risk Behavior Survey the Hong Kong adolescents had very low levels of self-assessed health and life satisfaction. Among the different domains, family and school life were associated with the lowest satisfaction level. There were strong male advantages in self-assessed health and migrant disadvantages in life satisfaction. Age was negatively related to both health and life satisfaction. Two-parent family was a positive factor for adolescents’ quality of life but economic well-being was not a relevant factor.  相似文献

In this article, a framework is suggested to deal with the analysis of global environmental risk governance. Climate Change is taken as a particular form of contemporary environmental risk, and mobilised to refine and characterize some salient aspects of new governance challenges. A governance framework is elaborated along three basic features: (1) a close relationship with science, (2) an in-built reflexivity, and (3) forms of governmentality. The UNFCCC-centered system is then assessed according to this three-tier framework. While the two-first requisites are largely met, the analysis of governmentality points to some institutional weak spots.  相似文献

积极心理资本:测量及其与心理健康的关系   总被引:6,自引:0,他引:6  
在文献分析和参考国内外相关测量工具的基础上,编制了包含自我效能、韧性、乐观、希望等4个因子的积极心理资本问卷(PPQ)。信度和效度验证的结果显示,该问卷具有良好的结构效度和内部一致性信度;验证性因子分析的结果也支持了心理资本这一高阶因子的合理性。研究还发现,积极心理资本及其子成分与自尊、内控性、情感平衡以及焦虑、抑郁、偏执、人际敏感等心理健康指标有显著的相关,回归分析的结果也显示心理资本对心理健康有积极的促进作用。  相似文献

In representational momentum (RM), the final position of a moving target is mislocalized in the direction of motion. Here, the effect of a concurrent sound on visual RM was demonstrated. A visual stimulus moved horizontally and disappeared at unpredictable positions. A complex tone without any motion cues was presented continuously from the beginning of the visual motion. As compared with a silent condition, the RM magnitude increased when the sound lasted longer than and decreased when it did not last as long as the visual motion. However, the RM was unchanged when a brief complex tone was presented before or after the target disappeared (Experiment 2) or when the onset of the long-lasting sound was not synchronized with that of the visual motion (Experiments 3 and 4). These findings suggest that visual motion representation can be modulated by a sound if the visual motion information is firmly associated with the auditory information.  相似文献

The present study has investigated the occurrence of body image dissatisfaction among adolescent schoolgirls in Amman, Jordan, and the risk factors that are known to predispose it including individual, familial and social variables. A sample of 326 adolescent girls aged 10–16 years was recruited from public and private schools in Amman. Participants completed a socio-demographic data sheet, eating attitude test, and body shape questionnaire. Approximately, 21.2% of participants displayed body image dissatisfaction in which physical changes associated with puberty and exhibiting negative eating attitudes were associated with this dissatisfaction. Additionally, mass media messages, as well as peers and family pressures towards thinness were associated with participants’ preoccupation with their body image. In conclusion, negative body image perception was observed in the present sample. Therefore, well-controlled prospective studies and development of intervention programs on body image among adolescent girls in Jordan are needed.  相似文献

A great deal has been made of the question of whether nano-materials provide a unique set of ethical challenges. Equally important is the question of whether they provide a unique set of regulatory challenges. In the last 18 months, the US Environmental Protection Agency has begun the process of trying to meet the regulatory challenge of nano using the Toxic Substances Control Act (1976)(TSCA). In this central piece of legislation, ‘newness’ is a critical concept. Current EPA policy, we argue, does not adequately (or ethically) deal with the novelty of nano. This paper is an exploration of how to do a better job of accounting for nanomaterials as ‘new.’ We explore three alternative ways that nanomaterials might be made to fall under the TSCA regulatory umbrella. Since nanomaterials are of interest precisely because of the exciting new properties that emerge at the nano-scale, each of these three alternatives must meet what we call the ‘novelty condition’ and avoid what we call the ‘central paradox’ of existing regulatory policy. Failure to meet either of these conditions is a moral failure. We examine both the strengths and weaknesses of each alternative in order to illuminate the conceptual, practical, and moral challenges of novelty.  相似文献

大学生专业适应性、学习倦怠与学习策略的关系   总被引:1,自引:0,他引:1  
采用大学生专业适应性问卷、学习倦怠量表和学习策略问卷,对802名大学生进行了测试,考察了大学生专业适应性、学习倦怠和学习策略的基本状况,以及专业适应性、学习倦怠与学习策略的关系。结果表明:大学生的专业适应性、学习倦怠和学习策略整体情况良好,但也有相当比例的大学生缺乏有效的学习策略,专业适应不良并表现出学习倦怠倾向;专业适应性对学习策略有显著的正向预测作用;学习倦怠对学习策略有负向预测作用,并在专业适应性和学习策略之间起部分中介作用。  相似文献
