al., 1999 ). In explaining the findings, Adams ( 1986 ), and others (e.g., Blandin & Proteau, 2000 ; Lee & White, 1990 ) proposed that, when watching a learning model, the observer engages in problem solving cognitions that form the basis of motor learning, including appraising/evaluating actions and

It was hypothesized that a combined Taoist Tai Chi (TTC) and a memory intervention program (MIP) would be superior to a MIP alone in improving everyday memory behaviors in individuals with amnestic mild cognitive impairment (aMCI). A secondary hypothesis was that TTC would improve cognition, self-reported health status, gait, and balance.
A total of 48 individuals were randomly assigned to take part in MIP + TTC or MIP alone. The TTC intervention consisted of twenty 90 min sessions. Outcome measures were given at baseline, and after 10 and 22 weeks.
Both groups significantly increased their memory strategy knowledge and use, ratings of physical health, processing speed, everyday memory, and visual attention. No preferential benefit was found for individuals in the MIP + TTC group on cognition, gait, or balance measures.
Contrary to expectations, TTC exercise did not specifically improve cognition or physical mobility. Explanations for null findings are explored.

This field study investigated sport-related and psychological predictors of children's performance outcomes (win-loss) across two consecutive rounds of a competitive wrestling tournament. The 76 wrestlers studied were 9- to 14-year-old boys, and the sport-related variable examined involved their years of competitive wrestling experience. The psychological predictors investigated were the participants' prematch performance expectancies and their characteristic prematch cognitions including: (a) worries about failure and (b) concerns about the performance expectations and evaluative reactions of their parents and coach. The data for each round were separately analyzed by logistic regression analysis. The most influential and stable predictors of performance outcomes across both tournament rounds were competitive experience and prematch performance expectancies. In addition, characteristic failure cognitions significantly predicted win-loss in the first round of the tournament. In total, win-loss was successfully predicted in 78 and 80% of the cases for round 1 and 2, respectively, by these predictors.

Maintenance of physical activity and good physical fitness is important for functional independence. This study had two aims: examine the physical fitness level in older persons with mild cognitive impairment (MCI) or dementia, and examine the relationship between the components of physical fitness and cognitive domains in this group. The cross-sectional study included community-living older people ≥ 65 years of age with MCI or dementia. Physical fitness and cognition were assessed using the Senior Fitness Test and five cognitive tests. Most of the participants scored below the criteria for maintaining physical independence in later years. There were significant associations between the components of physical fitness and cognition, except flexibility. Declines in executive function were most related to declines in physical fitness. These factors should receive more attention in people with MCI and dementia because they risk losing independence.

Nearly 200 studies have examined the impact that either acute or long-term exercise has upon cognition. Subsets of these studies have been reviewed using the traditional narrative method, and the common conclusion has been that the results are mixed. Therefore, a more comprehensive review is needed that includes all available studies and that provides a more objective and reproducible review process. Thus, a meta-analytic review was conducted that included all relevant studies with sufficient information for the calculation of effect size (N = 134). The overall effect size was 0.25, suggesting that exercise has a small positive effect on cognition. Examination of the moderator variables indicated that characteristics related to the exercise paradigm, the participants, the cognitive tests, and the quality of the study influence effect size. However, the most important finding was that as experimental rigor decreased, effect size increased. Therefore, more studies need to be conducted that emphasize experimental rigor.

Through lively music and coordinated dance movements, square dancing also engages various cognitions, such as executive function, memory, and motor skills. 7 In addition, square dancing creates a socially enriched environment for participants to interact with peers. 5 Square dancing is physically and

Despite an increase in the prevalence of yoga exercise, research focusing on the relationship between yoga exercise and cognition is limited. The purpose of this study was to examine the effects of an acute yoga exercise session, relative to aerobic exercise, on cognitive performance.
A repeated measures design was employed where 30 female college-aged participants (Mean age = 20.07, SD = 1.95) completed 3 counterbalanced testing sessions: a yoga exercise session, an aerobic exercise session, and a baseline assessment. The flanker and n-back tasks were used to measure cognitive performance.
Results showed that cognitive performance after the yoga exercise bout was significantly superior (ie, shorter reaction times, increased accuracy) as compared with the aerobic and baseline conditions for both inhibition and working memory tasks. The aerobic and baseline performance was not significantly different, contradicting some of the previous findings in the acute aerobic exercise and cognition literature.
These findings are discussed relative to the need to explore the effects of other nontraditional modes of exercise such as yoga on cognition and the importance of time elapsed between the cessation of the exercise bout and the initiation of cognitive assessments in improving task performance.

Youth sport research has failed to address the influential role of socialization agents in shaping children's motivational processes in sport. The purpose of this paper is to encourage the integration of socialization influences, particularly parental behaviors, into the study of children's sport motivation. The impact of socialization influences in shaping those cognitions widely regarded to influence children's sport behavior is examined. Special attention is paid to related research in academic settings that identifies the influence of parental socialization patterns upon children's self-perception characteristics, orientations toward achievement, and patterns of motivated behavior. Recommendations are made for incorporating socialization influences into youth sport research within the framework of cognitive-developmental theory.

Using meta-analysis, the impact of a number of manifestations of social influence (important others, family, class leaders, coexercisers, social cohesion, and task cohesion) on exercise behaviors (adherence and compliance), cognitions (intentions and efficacy), and affect (satisfaction and attitude) was examined. The results showed that social influence generally has a small to moderate positive effect (i.e., effect size [ES] from .20 to .50). However, four moderate to large effect sizes (i.e., ES from .50 to .80) were found: family support and attitudes about exercise, task cohesion and adherence behavior, important others and attitudes about exercise, and family support and compliance behavior.

Background: Research regarding the impact of aquatic exercise on cognition is scarce. This study aimed at identifying the effects of water-based exercise training on the cognitive function and quality of life of healthy adult women. Methods: Fifty-one healthy women [mean age: 46.5 (12.3) y] were assigned to group A or B and followed a water-based exercise program for 6 months. During the first 3 months, the sessions performed by group A were focused on stimulating cognitive function. For the next 3 months, the sessions were mainly aimed at improving physical fitness. Participants in group B followed the same program in reverse order. The trail making and symbol digit modality tests were used to assess the impact of the program on cognition. The effects of the intervention on the participants’ physical and mental health were measured by means of the medical outcomes study 36-item short-form health survey. Results: Once the intervention ended, significant improvements were observed in the participants’ cognitive function and mental health domain, regardless of the group in which they were initially included. Conclusion: Water-based exercise is a training modality capable of enhancing cognitive function and quality of life through improvements in mental health in healthy adult women.
