Problem‐construction and problem‐finding activities have been shown to have a marked impact on creative achievement. Although cognitive operations play an important role in problem construction, there is reason to suspect that personality variables might influence effective process application. In the present study we constructed measures of personality characteristics that might influence adaption to novel, ill‐defined tasks. These measures were administered to 250 undergraduates who were also asked to complete a problem‐construction task. A series of discriminant analyses indicated that personality variables could be used to identify individuals who generated high‐quality, original problems. The implications of our findings for understanding exactly how personality variables interact with cognitive operations in the problem‐construction process are discussed.  相似文献

To evaluate the efficacy of cognitive rehabilitation therapies (CRTs) for mild cognitive impairment (MCI). Our review revealed a need for evidence-based treatments for MCI and a lack of a theoretical rehabilitation model to guide the development and evaluation of these interventions. We have thus proposed a theoretical rehabilitation model of MCI that yields key intervention targets–cognitive compromise, functional compromise, neuropsychiatric symptoms, and modifiable risk and protective factors known to be associated with MCI and dementia. Our model additionally defines specific cognitive rehabilitation approaches that may directly or indirectly target key outcomes–restorative cognitive training, compensatory cognitive training, lifestyle interventions, and psychotherapeutic techniques. Fourteen randomized controlled trials met inclusion criteria and were reviewed. Studies markedly varied in terms of intervention approaches and selected outcome measures and were frequently hampered by design limitations. The bulk of the evidence suggested that CRTs can change targeted behaviors in individuals with MCI and that CRTs are associated with improvements in objective cognitive performance, but the pattern of effects on specific cognitive domains was inconsistent across studies. Other important outcomes (i.e., daily functioning, quality of life, neuropsychiatric symptom severity) were infrequently assessed across studies. Few studies evaluated long-term outcomes or the impact of CRTs on conversion rates from MCI to dementia or normal cognition. Overall, results from trials are promising but inconclusive. Additional well-designed and adequately powered trials are warranted and required before CRTs for MCI can be considered evidence-based.  相似文献

We assessed the role of parental behaviors on sport performance anxiety. Measures of trait anxiety, parental pressure, and parent-initiated motivational climate were administered to youth swimmers throughout the season. High parental pressure within either a low mastery or a high ego motivational climate was associated with the highest levels of anxiety at all time points. An early-season, high-pressure/low-mastery combination was also associated with relative increases in anxiety over the season, whereas high pressure within a high mastery climate was associated with relative decreases. Results indicate that parental pressure can have differential effects depending upon motivational climate.  相似文献

One hundred fifty-one children and 43 adults judged which of 2 cartoon birds would be the first to arrive at a common finish line. Objects moved unidirectionally along parallel trajectories, either at the same or different speeds, and disappeared at different distances from the goal. Overall, 9–10-year-old children performed as well as adults, but 4–5- and 6–8-year-olds erred significantly more often. On trials for which distance to goal at disappearance was a valid cue, 4–5-year-olds scored 80% correct, and no differences were seen between 6–10-year-olds and adults. On the opposite type of trials, where the trailing bird would win the race, only adults retained their level of performance, and all age groups differed markedly. Findings suggest a gradual developmental transition from a distance-based to a time-based understanding of the task.  相似文献

This study was designed to examine psychological characteristics and their development in Olympic champions. Ten U.S. Olympic champions (winners of 32 Olympic medals) were interviewed, as were one of their coaches ( n = 10), and a parent, guardian, or significant other ( n = 10). A battery of psychological inventories was also administered to the athletes. It was found that the athletes were characterized by: (a) the ability to cope with and control anxiety; (b) confidence; (c) mental toughness/resiliency; (d) sport intelligence; (e) the ability to focus and block out distractions; (f) competitiveness; (g) a hard-work ethic; (h) the ability to set and achieve goals; (i) coachability; (j) high levels of dispositional hope; (k) optimism; and (l) adaptive perfectionism. Results also revealed that a number of individuals and institutions influenced the athletes' psychological development including the community, family, the individual himself or herself, non-sport personnel, sport environment personnel, and the sport process. Coach and family influences were particularly important. Ways in which these sources influenced the athletes were both direct, like teaching or emphasizing certain psychological lessons, and indirect, involving modeling or unintentionally creating certain psychological environments. Psychological characteristic findings verified current sport psychological research on psychological characteristics associated with peak performance (Williams & Krane, 2001). They also suggest that adaptive perfectionism, dispositional hope, and high levels of optimism are new variables to consider. Results are also discussed relative to Bloom's (1985), Côtè's (1999) and Csikzentmihalyi, Rathunde, Whalen, and Wong's (1993) talent development research. Practical implications focus on implementing parenting and coaching practices related to the development of psychological characteristics associated with athletic success.  相似文献

Abstract

A meta-analysis was conducted on 40 studies (76 effects) in order to examine exercise training as a method of stress-management treatment for adults. It offered evidence of a low-to-moderate positive effect in anxiety reduction. Exercise training studies that examined change from pre to post-treatment and studies that examined both change over time and between group differences were examined separately. The unbiased weighted average effect sizes were .45 and .36, respectively. Thus, exercise training improved anxiety levels an average of .36 standard deviations over alternative or control conditions. Adults who were more likely to have a stressful lifestyle benefited more from the exercise training than those who did not. Recommendations are made for both practice and research.  相似文献

The purpose of this study was to evaluate the effectiveness of two different psychological skills training (PST) packages in enhancing mental toughness among three youth-aged (under 15 years old) Australian football teams. We compared a program targeting the keys to mental toughness identified previously (Gucciardi, Gordon, & Dimmock, 2008 Gucciardi, D. F., Gordon, S. and Dimmock, J. A. 2008. Towards an understanding of mental toughness in Australian football. Journal of Applied Sport Psychology, 20: 261281. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) with a more traditional PST program targeting self-regulation, arousal regulation, mental rehearsal, attentional control, self-efficacy, and ideal performance state as well as a control group. Overall, both intervention groups reported more positive changes in subjective ratings of mental toughness, resilience, and flow than the control group. Similar ratings for mental toughness were reported by the parents and coaches. Both PST packages appeared to be equally effective in enhancing mental toughness.  相似文献

This article builds upon and expands an earlier research project on the moral panic that surrounded the Harry Potter books and movies from 1997 through the first decade of the twenty-first century. Soulliere focused on the publications and public pronouncements of religious groups and leaders, media, and research organizations linked together by “the promotion of traditional values and a conservative ideology as well as a Judeo-Christian worldview, primacy of the family, and emphases on biblical foundations and authority” (Soulliere paragraph 14), which he refers to as the Christian Right. The current study seeks to discover the degree to which, if any, this moral panic extended beyond the Christian Right into the pulpits of mainstream Protestant denominations.  相似文献
