The study aimed to test the significance of sports participation as a potential means of improving cognitive function, particularly cognitive flexibility. Based on the characteristics of orienteering, such as frequent changes of behavioural strategies in response to changes in the situation or the simultaneous performance of several mental activities, we assumed that practising this sport could foster the development of cognitive flexibility. Two groups of volunteers were compared: 50 middle and long-distance runners and 50 orienteering runners in terms of their performance on the following measures of cognitive flexibility: a divergent thinking task, a computer flexibility task, Cognitive Flexibility Scale, and Verbal Fluency Test as a measure of executive function. Orienteering runners outperformed others on all measures except the Cognitive Flexibility Scale. Furthermore, we found that training characteristics (regularity, frequency, participation in competitions) were associated with levels of cognitive flexibility, particularly among orienteering runners, where they explained between 38% and 39% of the overall flexibility variance. Our results suggest that cognitive flexibility can be developed through sports training requiring effective dealing in a changing, complex environment. We also discuss the implications of our results for cognitive training research.  相似文献

A program to teach three severely retarded adults to use a side-of-the-foot soccer pass was evaluated. A 9-step stimulus-response chain was taught using forward chaining. In contrast to usual practice, intensive physical prompts were provided initially to teach each response component, then systematically faded. Approximately 20 lessons (trials) were presented in 20-min sessions. A multiple baseline across subjects design showed that the three trainees achieved the no-prompt criterion after 24, 29, and 22 sessions, respectively. Subanalyses indicated that successive response components were learned only after training was implemented. Follow-up data were obtained 57 and 276 days later in the training room and in a gymnasium; in both settings, criterion was achieved with fewer than three reinstructions.  相似文献

Homeless people face everyday challenges of marginalisation and stigmatisation. Consequently, they can suffer from low self‐confidence, self‐efficacy and agency. Empirical research in Britain on educational, skill‐building and meaningful activities for homeless people principally emphasises the instrumental value of training and learning as a route to employment rather than the impact of activities on homeless people's everyday lives. Theoretical literature suggests that psychosocial benefits related to the development of self‐efficacy, agency and empowerment can be gained from such activities. Participants' experiences and perceptions of educational and recreational activities were examined through 29 interviews at three homeless day centres in London. Thematic analysis suggests the restorative power of engagement in activities and shows that participants value activities, not only as the foundation for future goals of finding employment and housing, but as an immediate way of restoring a sense of self and finding positive experiences with a focus on the present. The findings underline the importance of viewing these interventions from a ‘bottom‐up’ perspective. The study tentatively concludes that accepting and emphasising the immediate personal benefits as a positive achievement of activities may be a valuable approach to better engage homeless clients.

The relationship between adolescent extra‐curricular activities and choice of graduate‐education field was examined among students from three fields of study, science (n = 12), art (n = 12), and education (n = 14), using qualitative and quantitative methods. Results of profile analysis indicated that the different majors participated in stereotypically varying activities when they were adolescents. Science majors generally participated in mathematics and science activities during adolescence. Art majors generally participated in theater and music activities, and education majors tended to have participated in social leadership and educational activities. Interviews with the participants supported these findings and provided a more comprehensive discussion of these tendencies. While in high school, the participants had many influences when determining a field of study. Using personal happiness as a guide, the participants chose activities and ultimately graduate‐level majors that reflected their interests. It was concluded that adolescent extra‐curricular activities are important in the development of interest in creatively talented individuals and may lead to graduate field selection.  相似文献

Two experiments were conducted (1) to explore the application of token reinforcement procedures in a maximum security correctional institution for adult male felons and (2) to determine to what extent the reinforcement procedures disrupted the day-to-day lives of inmate participants. In Experiment 1, an expanded reversal design revealed that the combination of praise and token reinforcement was more effective than the combinations of praise and noncontingent token award or direct commands on four common institutional activities. The latter two combinations were not found to be any more effective than praise alone. Experiment 2, which also employed a reversal design, indicated that the high levels of performance observed during the token reinforcement phases of Experiment 1 could be attained without subjecting participants to undue hardship in the form of increased deprivation of either social intercourse or the opportunity to engage in recreational and entertainment activities. Client safeguards are discussed in detail.  相似文献

Nursing-home residents have frequently been characterized as unoccupied and disengaged. At the outset of the present study, most residents were to be found in their own rooms, not exhibiting gross motor behavior or social interaction, and not participating in appropriate activities. To modify residents' levels of participation with the environment, a manipulative area was provided in the lounge. Participation in the lounge averaged 20% on days when the activity was not available, but increased to a mean of 74% on days when equipment and materials were given and residents were prompted to participate. When prompts were withdrawn and materials were available only by request, mean participation fell to 25%. The findings demonstrate that manipulative activities can support a high level of participation with the environment, if residents are prompted to use equipment and materials.  相似文献

The importance of routines for the performance of everyday activities   总被引:1,自引:0,他引:1  
Whether the weekly frequency with which everyday activities (e.g., taking a shower, running for exercise) are performed is determined by intentions to perform the activities at different frequencies rather than by routines was investigated. Sixty-four subjects participated in an experiment in which self-reported frequency of performance of 10 activities was predicted from indicated intentions as well as from self-reports of the frequency with which the activities were performed a previous week. The results were as expected for a few of the activities, whereas for a majority of them performance was predicted from previous frequency without the mediation of intentions. Consistent with the conclusion that routines played a more important role than intentions, it was also found that intentions failed to predict performance better the following week than it predicted performance the week after that week. Conditions under which intentions may be a more important determinant were discussed.  相似文献

Two experiments explored the effects of two types of concurrent activity on human fixed-interval performance. Eight adult subjects were given access to either reading material or a working television set across three fixed-interval values (60 s, 300 s, and 600 s). During Experiment 1, 2 subjects produced "scalloped" patterns and reported no verbal regulation (e.g., counting) in the presence of the reading material, but shifted to low-rate patterns and reported verbal regulation when the reading material was withdrawn. The 2 other subjects in Experiment 1 produced consistent low-rate performances and reported verbal regulation during access to reading material. However, when these subjects were given access to a working television set, they produced scalloped patterns and reported no verbal regulation. During Experiment 2, 4 experimentally naive subjects showed consistent scalloped patterning and no verbal regulation across fixed-interval values when they were allowed to watch television. When access to the television was denied, subjects reliably reported verbal regulation, and low-rate patterns emerged. These behavioral effects focus our attention on the contingencies that control human performance on fixed-interval schedules.  相似文献

The aim of this study was two-fold: (i) to compare passion, grit and mindset between sexes; and (ii) to analyze the relationships between passion, grit and mindset. Fifty-eight men (age: 20.10 ± 2.70 years old) and forty-eight women (age: 19.27 ± 4.10 years old) sports sciences undergraduate students voluntarily participated in this study. A cross-sectional survey design was followed. The passion scale, grit scale and mindset scale were provided to participants. Comparisons in the passion, grit and mindset items revealed no significant differences between sexes (p > 0.05). Relationships between passion, grit and mindset were tested. Overall (both sexes considered), correlations presented small magnitudes in the pair's passion*grit (r = 0.28; 95%CI [-0.07; 0.31]; p = 0.004), passion*mindset (r = 0.203; 95%CI [0.01; 0.38]; p = 0.043) and grit*mindset (r = 0.06; 95%CI [-0.14; 0.25]; p = 0.574). As conclusions, the present study did not find significant differences in passion, grit and mindset between sexes in undergraduate sports sciences students. Additionally, it was verified that relationships between passion, grit and mindset are small in this population.  相似文献

In the present study, we examined intra‐individual relations among emotions when receiving test results and subsequent test review activities, and the direct and moderating effects of perceptions of test value. The participants, 90 first‐year students at a private girls' secondary school, self‐reported their present emotional state immediately after receiving their test results and their test review activities 1 week after the tests were returned. The same survey was conducted on four occasions. Results of multilevel analyses indicated that emotions experienced when receiving test results did not predict subsequent learning behavior. The results also showed that relations among emotions and review activities differed across students. Although we investigated whether such individual differences in relations might be attributed to perceptions of test value, no moderating effect could be observed. Furthermore, improvement‐oriented test mindsets were found to be positive predictors of review activities by investigating the direct effect of perceptions of test value. These findings suggest that modifying students' perceptions of test value may promote appropriate learning behavior.  相似文献
