Objective: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image.

Design: Fourteen women aged 22–45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis.

Results: Scans did not look as expected, and participants expressed ‘surprise’ and ‘shock’. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too ‘real’ and ‘raw’. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning.

Conclusion: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.  相似文献

Individuals identified as at high risk of developing Hereditary Diffuse Gastric Cancer (HDGC) are advised to undergo prophylactic surgery - have their stomach removed - in their early twenties. Research with (older) cancer patients who undergo gastrectomy for curative reasons suggests that gastric resection has a number of physical and psychosocial sequelae. Because it is difficult to extrapolate the findings of studies of older cancer patients to younger healthy patients who are considering prophylactic total gastrectomy (PTG), the aim of this qualitative interview study was to determine the psychosocial implications of undergoing prophylactic surgery to manage genetic risk. Fourteen men and 13 women from the UK’s Familial Gastric Cancer study who had undergone PTG were invited to participate in qualitative interviews. Most reported that undergoing surgery and convalescence was easier than anticipated. There was evidence that age affected experiences of PTG, with younger patients tending to report faster recovery times and more transient aftereffects. All saw the benefits of risk reduction as outweighing the costs of surgery. Surgery was described as having a range of physical impacts (disrupted appetite, weight loss, fatigue, GI symptoms) that had related psychological, social and economic implications. Those considering PTG need to be aware that its impact on quality of life is difficult to predict and negative sequelae may be ongoing for some individuals.  相似文献

This study investigates economic locus of control (ELOC) in a Greek sample using Furnham's (1986) scale. In particular, it examines the association between ELOC and saving behavior and motives, attitudes toward state intervention in the economic field, and factors engendering confidence in economic matters. The main hypotheses predicted that internal ELOC should be associated with (a) desire for less state intervention; (b) confidence in factors under one's own control (knowing the other party in transactions, being well informed) more strongly than with other factors of economic trust, such as the state and the law; (c) more saving; and (d) that respondents with internal and external ELOC should be differentiated with respect to saving motives. Analysis was based on a sample of 135 participants from Athens. Principal components analysis of the Greek translation of Furnham's ELOC questionnaire gave results similar to those reported from England, yielding 4 factors interpretable as chance, internal, external/denial, and powerful others. The findings of the study include confirmation of all of the hypotheses.  相似文献

Name learning strategies including retrieval practice, semantic associations and imagery were compared in laboratory‐based and real‐life experiments. Experiments 1 and 2 studied expanding retrieval practice and a semantic association strategy as memory improvement techniques for learning proper names. Participants either retrieved or restudied names on the same, expanding schedule. After a short, filled interval, cued recall of names was about 250% better following retrieval than restudy and 200% better with than without semantic associations. Together, the techniques improved recall by 300–400%. In Experiment 3, retrieval practice was compared with an imagery mnemonic for name learning under real‐life social conditions: Participants sought to learn the names of people they met at a party. Retrieval practice produced 50% higher recall after 24–72 hours but the imagery mnemonic was no more effective than non‐directed instructions to learn names.

Three experiments investigated whether women can change their walking style and hence reduce their vulnerability to physical attack. In Experiment 1, women were videotaped walking normally and when imagining themselves in a situation of low personal safety. Women were rated as harder to attack in the low safety condition. Differences in walking style accounted for differences in ease‐of‐attack ratings. Experiment 2 compared walking styles and vulnerability of women before and after completing a self‐defense course. No differences were seen across sessions. Experiment 3 investigated walking styles and vulnerability of women before and after completing individualized walking training programs. Differences in vulnerability between sessions were revealed and could be accounted for by changes in walking‐style features.  相似文献

As part of the larger project to revision vocational psychology for a new era, a process referred to as the emergence of new intentions in subjective experience is defined and described. It is proposed that this process is central to the ongoing construction and reconstruction of lives in the changing landscape of the times. Following an elaboration of the meaning of emergence of new intentions in subjective experience through comparison to related constructs and theories, a social/personal constructionist and relational understanding of this process is developed. The article concludes by addressing implications for vocational psychology practice.  相似文献

The present study investigated verbal and spatial working memory (WM) functioning in individuals with the neuro-developmental disorder Williams syndrome (WS) using WM component tasks. While there is strong evidence of WM impairments in WS, previous research has focused on short-term memory and has neglected assessment of executive components of WM. There is a particular lack of consensus concerning the profile of verbal WM functioning in WS. Here, WS participants were compared to typically developing participants matched for (1) verbal ability and (2) spatial ability (N = 14 in each of the 3 groups). Individuals with WS were impaired on verbal WM tasks, both those involving short-term maintenance of information and executive manipulation, in comparison to verbal-matched controls. Surprisingly, individuals with WS were not impaired on a spatial task assessing short-term maintenance of information in memory (remembering spatial locations) compared to spatial-matched controls. They were, however, impaired on a spatial executive WM task requiring the manipulation of spatial information in memory. The present study suggests that individuals with WS show WM impairments that extend to both verbal and spatial domains, although spatial deficits are selective to executive aspects of WM function.  相似文献

Construction tasks form a major part of children's play and can be linked to achievement in maths and science. However there is a lack of understanding of construction task ability and development. Therefore, there is little foundation for the applied use of construction tasks, such as in teaching or research, as there are no apparent methods for assessing difficulty. This empirical research identifies four construction task characteristics that impact on cognition and predict construction task difficulty in children aged 7–8 and 10–11 years and adults. The results also reveal a developmental trajectory in construction ability. The research provides a method to quantify, predict and control the complexity of construction tasks for future research and to inform applied use. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Openness to Experience and Need for Closure (NFC) are dispositional variables related to social‐cultural right‐wing attitudes. The present study investigated their joint effects. Factor analysis revealed an ‘experiential’ dimension with high loading openness items, and a ‘cognition’ dimension with high loadings for most NFC items and about a quarter of the openness item set. The experiential openness items were weakly related to right‐wing attitudes, demonstrating little predictive value. Conversely, the cognitive openness and NFC items were powerful predictors of right‐wing attitudes, and also played an important role in integrative models, both as a predictor of authoritarianism‐based racism and as a mediator of age related increments in right‐wing attitudes. It is concluded that right‐wing attitudes should be primarily understood in terms of (motivated) cognition, and to a smaller extent in terms of experiential openness. The distinction between ‘experiential’ and ‘cognitive’ openness is critically assessed, and it is asserted that because cognition is a multifaceted construct openness contains more than one cognitive dimension.

In response to concerns with existing procedures for measuring strategic control over implicit knowledge in artificial grammar learning (AGL), we introduce a more stringent measurement procedure. After two separate training blocks which each consisted of letter strings derived from a different grammar, participants either judged the grammaticality of novel letter strings with respect to only one of these two grammars (pure-block condition), or had the target grammar varying randomly from trial to trial (novel mixed-block condition) which required a higher degree of conscious flexible control. Random variation in the colour and font of letters was introduced to disguise the nature of the rule and reduce explicit learning. Strategic control was observed both in the pure-block and mixed-block conditions, and even among participants who did not realise the rule was based on letter identity. This indicated detailed strategic control in the absence of explicit learning.  相似文献
