This study examined the knowledge base and perspectives of current and retired gymnasts, parents, coaches and judges with respect to disordered eating in gymnasts. Surveys were designed for this study and included open-ended questions, Likert scales, and checklists. The results indicated that various discrepancies existed between the groups' reports. For example, the retired gymnasts reported more eating disorders and negative views of their experiences than did the current gymnasts. The coaches attributed the use of unhealthy weight control practices to other coaches but not to themselves. Gymnasts who received disparaging comments about their bodies or instructions to lose weight had significantly more disordered eating patterns than those who had not received such comments. The importance of one's social environment on eating and weight control practices is emphasized. Every group recommended further education about nutrition, adolescent development, body image, and psychological well-being. Limitations and future recommendations are addressed.  相似文献

This chapter examines the role of leadership in overcoming social dilemmas within groups. First, based on prior theorising and research we present two alternative perspectives on leader endorsement in social dilemmas, an instrumental and a relational perspective. Next, we systematically compare these perspectives in a series of experiments investigating leadership in social dilemmas created within small groups in the laboratory. The results of our studies suggest that when their personal identity is salient, group members more strongly endorse leaders who are perceived to be instrumental in solving the freerider problem. In contrast, when a social identity is salient, members more strongly endorse leaders who fulfil their relational needs. Based on these findings we propose a differential needs model of leader endorsement in social dilemmas.  相似文献

In attitude research, behaviours are often used as proxies for attitudes and attitudinal processes. This practice is problematic because it conflates the behaviours that need to be explained (explanandum) with the mental constructs that are used to explain these behaviours (explanans). In the current chapter we propose a meta-theoretical framework that resolves this problem by distinguishing between two levels of analysis. According to the proposed framework, attitude research can be conceptualised as the scientific study of evaluation. Evaluation is defined not in terms of mental constructs but in terms of elements in the environment, more specifically, as the effect of stimuli on evaluative responses. From this perspective, attitude research provides answers to two questions: (1) Which elements in the environment moderate evaluation? (2) What mental processes and representations mediate evaluation? Research on the first question provides explanations of evaluative responses in terms of elements in the environment (functional level of analysis); research on the second question offers explanations of evaluation in terms of mental processes and representations (cognitive level of analysis). These two levels of analysis are mutually supportive, in that better explanations at one level lead to better explanations at the other level. However, their mutually supportive relation requires a clear distinction between the concepts of their explanans and explanandum, which are conflated if behaviours are treated as proxies for mental constructs. The value of this functional-cognitive framework is illustrated by applying it to four central questions of attitude research.  相似文献

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Little is known about how applicants' selection expectations and perceptions interplay in predicting applicant attraction outcomes (organizational attractiveness, job pursuit intention, and recommendation intention). In the present study, 340 entry‐level applicants for jobs in a large financial company provided information about their selection expectations before the procedure, and about their perceptions and attraction to the organization after the procedure. Regression analyses indicated that applicant perceptions, and in particular perceptions of warmth/respect, mediated the relationship between selection expectations and organizational attractiveness and job pursuit intention. No support was found for the moderating role of selection expectations in the perception–attraction relationship. Implications for practice and future research are discussed.  相似文献

To date, a number of studies have demonstrated the existence of mismatches between children's implicit and explicit knowledge at certain points in development that become manifest by their gestures and gaze orientation in different problem solving contexts. Stimulated by this research, we used eye movement measurement to investigate the development of basic knowledge about numerical magnitude in primary school children. Sixty‐six children from grades one to three (i.e. 6–9 years) were presented with two parallel versions of a number line estimation task of which one was restricted to behavioural measures, whereas the other included the recording of eye movement data. The results of the eye movement experiment indicate a quantitative increase as well as a qualitative change in children's implicit knowledge about numerical magnitudes in this age group that precedes the overt, that is, behavioural, demonstration of explicit numerical knowledge. The finding that children's eye movements reveal substantially more about the presence of implicit precursors of later explicit knowledge in the numerical domain than classical approaches suggests further exploration of eye movement measurement as a potential early assessment tool of individual achievement levels in numerical processing.

The WHO/Start Study is introduced and described in its four main components. The study originated as a response to growing concerns about trends of suicide, the prevalence of which in the Western Pacific Region of the World Health Organization is the highest among the six regions of the WHO. So far, nineteen centers have joined the study. This ambitious project is expected to provide important transcultural perspectives on both fatal and nonfatal suicidal behaviors, together with increased awareness for these phenomena and the growth of culture‐sensitive prevention programs.  相似文献

The emergence of research interest in group violence in general and football hooliganism in particular has been explained by various models generally relying on situational or individual differences accounts. Yet, these two research traditions have largely evolved independently, showing little or no interaction. In the present study (N = 109), we integrate measures of these two approaches and the results reveal that social identity was more predictive of self‐reported physical aggression than of loss of private and public self‐awareness. Moreover, attitudes towards violence were the most marked predictor variables of both physical and verbal aggression. In the discussion, the moderator effect of social identity and attitudes about violence on physical aggression is elaborated upon. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Research into adults' recall from different presentation modalities has demonstrated a recall advantage for print over television yet recent research indicates that children remember television news better than print news. An experiment was conducted by comparing children's and adults' recall of children's news stories presented in two different modalities, television and print, in order to establish whether children's recall advantage for television is dependent on their age or level of reading proficiency. A sample of 40 adults, 40 13‐year‐olds and 40 11‐year‐olds were presented with children's news stories, either in their original televised form or in a print version. All participants were aware they would be tested for recall. The results of the cued recall test indicated that children from both age groups learned more from the television news than from the print versions, regardless of age or reading proficiency and that adults remembered equal amounts from both presentation modalities. For the 11‐year‐olds the advantage of television was only found for information that had been accompanied by redundant pictures in the televised version, providing support for the dual‐coding hypothesis. For 13‐year‐olds the recall of television was not dependent on the addition of redundant visual information. Viewers and readers were found to invest the same amounts of mental effort, but reported levels of invested mental effort were found to be dependent on age and level of reading proficiency.
