This paper examines the contemporary phenomenon of obstacle challenges and why people participate in events that result in them getting soaking wet, freezing cold, and dirtier than they have ever been while also getting shot with pellets and receiving “electric shocks.” Many participants in these challenges have taken part numerous times and keep coming back for more. Using multiple research methods including questionnaires, participant observation where the author completed one of Ireland's more well‐known and “toughest physical and mental endurance challenges,” and also depth interviews with challenge participants has resulted in a rich and detailed account of the obstacle challenge experience. These events are so much more than a few hours of strenuous and muddy physical exercise. The sense of community and camaraderie that people experience during these challenges could be described as “transformative” with participants in many cases more rewarded and moved by this collaborative aspect than the gruelling physical endeavour that they undertake. The escapism provided by the experience is also one its main rewards, relief from the quotidian and the chance to just “be.” The servicescape proves to be critically important to the experience but in ways that are largely incompatible with research in this area to date in that the comfort and cleanliness expected of more traditional servicescapes are spurned and physical hardship is welcomed. As this is an exploratory and novel research topic, suggestions for further research are plentiful.  相似文献

Rapid automatized naming (RAN; Denckla & Rudel, 1976) tasks are consistent predictors of fluency that also discriminate between dyslexic and nondyslexic reading groups. The component processes of RAN that are responsible for its relationship with reading ability remain underspecified, however. We report a study on dyslexic and nondyslexic adult groups that experimentally manipulated RAN formats to elucidate how different components of RAN differentially influence dyslexic and nondyslexic performance. The dyslexic group showed a pervasive deficit in rapid access of individually presented items. Additionally, they showed a significant impairment when multiple items were presented, whereas nondyslexic readers showed marginal facilitation for this format. We discuss the implications of these findings with respect to reading-group differences in reading fluency.  相似文献

The present study extended previous research into the role of cognitive style in predicting depressive symptoms in children by examining positive attributional style for positive events in a prospective manner, with a focus on the influence of prior life experience. A non‐clinical sample of 102 children (aged 10–12 years) was recruited. Participants completed self‐report measures of depression, attributional style, stressful life events, and positive life events on two occasions (approximately 6 months apart). Positive attributional style for positive events moderated the relationship between negative life events and follow‐up depressive symptoms. Number of positive events did not significantly moderate the negative life events–depression symptoms relationship although there was a trend in the expected direction. Positive attributional style for positive events appeared to act as both a mediator and moderator in the positive events–depression symptoms relationship. Theoretical and clinical implications of these findings are discussed.  相似文献

The present study compared the efficacy of a group-based cognitive-behavioural treatment (GCBT) delivered exclusively to parents of young anxious children (between 4 and 8 years of age) with the same intervention delivered to both children and parents, relative to a Wait-list Control condition. Parents of children in the Parent Only condition (N = 25) received 10 weekly sessions of GCBT whereas children and parents in the Parent + Child condition (N = 24) each received 10 weekly sessions of GCBT. Intent-to-treat analyses indicated that both active treatment conditions were superior to the Wait-list condition (N = 11), with 55.3% of children in the Parent Only condition and 54.8% of children in the Parent + Child condition no longer meeting criteria for their principal diagnosis at post-treatment. These treatment gains were maintained in both treatment conditions at six-month and 12-month follow-up assessments. There were no significant differences between the two active conditions on other outcome measures including parental psychopathology and parenting style. However, an unexpected finding was that parenting satisfaction and to some extent parenting competence reduced significantly from pre- to post-treatment regardless of the active treatment condition. The present results suggest that GCBT delivered exclusively to parents of young anxious children may be a viable treatment alternative for improving accessibility to efficacious treatments for children with anxiety disorders and for reducing costs associated with mental health care delivery.  相似文献

Most cross‐cultural studies on country of origin or product‐country image (PCI) effects have implicitly assumed that national markets are composed of homogeneous consumers. Although many investigations in this field are described as cross‐cultural, most are in fact cross‐national. The overarching hypothesis of the present research is that PCI effects may vary across subcultures within a country. The results indicate that subcultural differences exist in the evaluation of culturally affiliated countries and their products. Cognitive responses converged to show that consumers' perceived linkages significantly influence the weight given to the country of origin in product evaluations. Several implications for managers and academic researchers are discussed. Copyright © 2003 Henry Stewart Publications.  相似文献

This investigation extends the constant time delay research base by embedding nontargeted information in the task direction when teaching communication skills. Specifically, instructors taught receptive identification of packaged food items to 4 secondary students with moderate to severe disabilities and evaluated generalization to the community. In addition, instructors included the manual sign for each food item. The instructional strategy was a constant time delay procedure using a 5-s delay interval. The intervention, conducted within a multiple probe design across behaviors replicated across students, resulted in the acquisition and generalization of receptive identification of packaged food items by 3 out of 4 of the students. In addition, the students acquired the nontargeted manual signs with an average of 60% percent in the final probe session.  相似文献

Two methods of monitoring the circadian rhythm of activity in rodents: (1) an activity wheel cage, which detects the number of wheel revolutions, and (2) an internal radio transmitter, which records gross motor activity (GMA) of the animal, were compared in both normal circadian cycles and during the development of activity-stress ulcers. Rats were implanted with a biotelemetry transmitter that detected GMA and body temperature (BT) and placed in activity wheel cages. A 12 hour/12 hour light/dark cycle was maintained throughout the experiment. Subjects were subdivided into two groups: (1) unlimited access to activity wheel (AW) cages and (2) locked activity wheel (LW) cages. Following an ad-libitum habituation period, animals were allowed food access for 1 hour/day during the light. In the habituation period, the animals showed higher GMA and BT during the dark phase when housed in AW cages than in LW cages. Both GMA and number of wheel revolutions increased dramatically after the onset of food restriction for the AW animals. There was a deleterious drop in BT in AW animals as the food-restricted period continued and a significant correlation existed between severity of ulcerations and BT. The findings of this experiment demonstrate that the activity wheel imposes an alternation of the circadian cycle, which, in turn, influences rhythmicity through reentrainment. Additionally, in the activity-stress paradigm, a significant drop in BT correlates with severity of ulcerations. A disrupted circadian cycle, involving hypothermia, is proposed as the mechanism underlying the demise of animals in the activity-stress paradigm.  相似文献

This study examined cross-sectional and prospective associations between cognitive appraisals and posttraumatic stress disorder (PTSD) symptoms following stroke. While in hospital, stroke patients (n=81) completed questionnaires assessing cognitive appraisals (i.e., negative cognitions about the self, negative cognitions about the world, and self-blame) and PTSD symptoms. PTSD symptoms were assessed again 3 months later when all patients had been discharged from hospital (n=70). Significant correlations were found between the time 1 measures of negative cognitions about the self and the world, but not self-blame, and the severity of PTSD symptoms measured at time 1 and at time 2. Regression analyses revealed that cognitive appraisals explained a significant amount of variance in the severity of PTSD symptoms at time 1, with negative cognitions about the self-emerging as a significant predictor. In contrast, time 1 cognitive appraisals were unable to explain additional variance in time 2 PTSD severity over and above that explained by time 1 PTSD severity. The findings therefore provide only weak support for Ehlers and Clark's cognitive model of PTSD.  相似文献

The purpose of this study was to explore the role of social preference and perceived acceptance as moderators of the relation between child temperament and externalizing behavior. Participants included 399 children evaluated at pre-kindergarten and kindergarten assessments. Pre-kindergarten children characterized by high temperamental Surgency/Extraversion were more likely to exhibit hyperactivity and aggression in the kindergarten classroom. In addition, kindergarten perceived acceptance and social preference moderated the relation between pre-kindergarten Surgency/Extraversion and kindergarten hyperactivity for girls only. Girls who were characterized by high temperamental Surgency/Extraversion, high perceived acceptance, and low social preference were at risk for higher levels of teacher-reported and peer-nominated hyperactivity. In contrast, accurately high perceived acceptance was a protective factor for high temperamental Surgency/Extraversion. Findings are discussed in terms of risk and protective factors for externalizing behavior.  相似文献
