Role and group identities are distinct yet related constructs. Both identities may be relevant to exercise yet exercise identity research has focused mostly on exercise role identity.ObjectiveWe examined the relationship between role and group identity among runners. Further, the relationship of runner role and running group identity were examined relative to social cognitive and behavioural outcomes relative to running and the possibility of running group disbandment.DesignAn observational design was used.MethodRunning group members completed measures of runner role and running group identity, self-efficacy for running, and aspects of recent exercise and anticipated reactions to running group disbandment.ResultsRunner role and running group identity showed a small, positive correlation. Runner role identity was associated with self-efficacy for running, vigorous exercise, less group running and adaptive reactions to the possibility of group disbandment. Running group identity was associated with negative self-efficacy, greater percentage of runs being conducted with the group and maladaptive reactions to group disbandment. Runner role and running group identity did not interact in their relationship to exercise-related outcomes.ConclusionsIn the context of running, role and group identities are related but unique variables. Identification as a runner may not only be associated with exercise in the context of the group but may also have protective effects against disruptions to group running. Identification with the running group may compromise exercise in the face of group disbandment. 相似文献

Tool-improvisation analogies are structure-mapping inferences implemented, in many species, by event-file binding and pre-motor action planning. These processes act on multi-modal representations of currently perceived situations and eventuate in motor acts that can be directly evaluated for success or failure; they employ implicit representations of force-motion relations encoded by the pre-motor system and do not depend on explicit, language-like representations of relational concepts. A detailed reconstruction of the analogical reasoning steps involved in Rutherford's and Bohr's development of the first quantized-orbit model of atomic structure is used to show that human force-motion analogies can in general be implemented by these mechanisms. This event-file manipulation model of the implementation of force-motion analogies is distinguished from the standard view that structure-mapping analogies require the manipulation of explicit, language-like representations of relational concepts. 相似文献

When homing from familiar areas, homing pigeons are able to exploit previously acquired topographical information, but the mechanisms behind this ability are still poorly understood. One possibility is that they recall the familiar release site topographical features in association with the home direction (site-specific compass orientation strategy), another that the spatial relationships among landmarks guide their route home (piloting strategy), without relying on the compass mechanism. The two strategies can be put in conflict by releasing clock-shifted birds at familiar locations, in order to highlight which is preferred. We analysed GPS tracks of clock-shifted pigeons, with familiarity controlled at each of three different release sites, and we observed that pigeons can display individual preferences for one of the two orientation strategies and that some characteristic features of the release site have an important role in determining the level of landmark-based homeward orientation. 相似文献

Aim: This article gives an overview of the setting up of the Art Therapy Practice Research Network (ATPRN) in 2000, amidst a culture resistant to research. The authors discuss their experiences in changing this culture and encouraging art therapists to become practitioner/researchers. They identify learning points that may be helpful for other professionals who want to form new practice research networks (PRNs). Context: The research and practice context contemporary to the ATPRN foundation is outlined and identified as a significant influence on its inception and development. Key events in the 14 years of the PRN's life and articles on art therapy and psychotherapy research published at the time of the ATPRN foundation are used to illuminate the historical context. ATPRN newsletters and symposium reports were consulted to identify themes and issues across 14 years of development and growth. Learning points: Several learning points are identified and listed as useful factors to address when setting up and maintaining a PRN and include: shape the culture from the start; review and revise; get practical together; encourage members' presentations; build synergy with professional body; embed the ATPRN around all aspects of research publication. Conclusions: Successful PRNs depend on making practitioners feel included from the start by acknowledging fear and anxiety about research. Providing practical projects helped practitioners to feel less isolated by being part of a meaningful and productive network. Maintaining and developing PRNs is an iterative process that demands constant reviewing and revising. 相似文献

This paper proposes a novel environmental marketing approach in which the adoption of greener consumer behaviours is encouraged by repositioning them as normal. The research was undertaken in order to help explain the disappointing performance of green marketing initiatives. The methodology was qualitative, with focus groups and a wide range of stimulus materials. The study illuminates the ways in which consumers conceptualise and adopt pro‐environmental behaviours and highlights the importance of consumer ideas about what is normal. The research indicates that consumers are more likely to adopt behaviour and products that they think are normal and that what is regarded as normal changes over time. New activities and products that are initially seen as different, and as outside normal behaviour, can eventually become mainstream and accepted as normal, in a process of ‘social normalisation’. As part of this process, other behaviours, which have been mainstream everyday ways of doing things, can become marginalised over time. The research suggests that companies and policy makers tend to position green marketing initiatives as targeting a green niche and that this inhibits social normalisation and mainstream adoption. Green marketing can potentially play an important role in the social normalisation of green practices and products by portraying these as normal and everyday instead of emphasizing their greenness. The study contributes to understanding of consumer behaviour and the adoption of more sustainable products and practices and identifies practical ways to improve green initiatives.

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion. 相似文献

Subjective well-being has been studied by social scientists for decades mostly in developed countries. Little is known about determinants of subjective well-being in developing countries and more particularly in Sub-Saharan Africa (SSA). Using 2005–2008 World Values Survey (n = 1,533) this study adds to existing literature on well-being in developing countries focusing on Ghana. The paper explores the predictors of two measures of subjective well-being—happiness and satisfaction in life at micro-level in Ghana. The analyses are divided into two main sections. The first part describes the distribution of happiness and satisfaction in life among Ghanaians. The second section elucidates factors influencing the selected measures of subjective well-being separately. The data reveal that both happiness and life satisfaction among Ghanaians are shaped by multitude of factors including economic, cultural, social capital and health variables. Relatively, perceived health status emerged as the most salient predictor of both measures of well-being. Besides religiosity, all the religion variables emerged as significant predictors of how Ghanaians appraise their own well-being. Equally, income, ethnicity and social capital variables emerged as predictors of happiness and life satisfaction at micro-level in Ghana. Policy implications of the findings are discussed alluding to multidimensional approach to well-being promotion in the country. The outcome of the study also establishes the fact that factors predicting subjective well-being at the micro level vary in SSA context compared to the developed world. 相似文献

Sensory input that is not available for conscious report can still affect our behavior. Recent findings suggest that such subliminal information has the potency to influence behavior in a way that is dependent on the observer’s current intentions. Here, we investigate whether conscious observation of stimulus relevance provides an incentive for the utilization of nonconscious stimuli. We manipulated the predictive power of directional cues to selectively affect the incentive to utilize them for a subsequent target detection task. Central arrow cues rendered invisible by interocular suppression elicited a facilitatory cuing effect, but only when intermixed with visible arrow cues that were highly predictive with respect to (i.e., 80 % congruent with) the subsequent target location. When the visible cues were nonpredictive (50 % congruent), no subliminal cuing effect was found. An analysis of learning effects corroborates these findings; Cuing effects elicited by both visible and invisible cues increased over the course of the experiment, but only when intermixed visible cues were highly predictive. In a second experiment, we demonstrated that the intrinsic relevance of invisible cues (either 50 % or 100 % congruent) has no effect on the utilization of visible cues. We conclude that conscious perception is required to make statistical inferences about the relevance of symbolic cues. Once statistical information is extracted consciously, it affects subsequent nonconscious processing in a way that fits the current context. Accordingly, one of the possible functions of consciousness could be to extract general rules out of the conscious information, to provide guidelines for future behavior. 相似文献

The current bio-psycho-social approach in South African psychiatry refers to Engel’s extended model of health care. It forms the basis of the existing collaboration between medicine, nursing, psychology, occupational therapy and social work. Psychiatry also has to bridge the multi-cultural, multi-religious and spiritual diverse reality of everyday practice. It has become important to establish how, within accepted boundaries, spirituality should be incorporated into the model for practice. Referring to methods described for nursing theory development, a defined core concept was used to construct a model. It may contribute to the discourse on spirituality in local psychiatry, health and mental health. 相似文献
