Psychological Mood Profiles of Sighted and Unsighted Beep Baseball Players

Purpose: Decline of motor performance in older individuals affects their quality of life. Understanding the contribution of sport-related training in advanced ages might help to attenuate motor performance decay as one gets older. The purpose of our study was to evaluate the extent to which long-lasting training in running or sport-specific skills during old age preserves motor performance in different motor tasks. Method: Older runners and tennis players with at least 10 years of training were assessed as were age-matched and young exercisers. Performance was evaluated for 6 motor tasks requiring different functions of sensorimotor control expected to decline with aging. Results: Analysis revealed that runners had increased aerobic fitness in comparison with the other older participants and that they presented similar performance to older exercisers in the motor tasks. Tennis players outperformed the other groups of older participants on coincident timing and simple reaction time and achieved similar performance to the young group on the timing task. Conclusions: These results suggest selective maintenance of task-specific processing through extensive practice of tennis-related motor skills in older adults.     

Distribution of Practice in Motor Skill Acquisition: Different Effects for Discrete and Continuous Tasks

Abstract

Research on the benefits of distributed practice for the acquisition and retention of motor skills has a long history. The majority of this research has involved skill acquisition of continuous tasks. However, there is some evidence to suggest that distribution of practice effects are quite different for discrete tasks than for continuous tasks. In the present study, we used a single task, formed discrete and continuous versions of the task, and examined how acquisition and retention were affected by the length of inter-trial interval. The basic task was a movement timing task that involved either one timing estimate per trial (the “discrete” version) or twenty successive estimates per trial (the “continuous” version). Separate groups of subjects learned one version of the task under either distributed (25 s inter-trial intervals) or massed (0.5 s inter-trial intervals) practice conditions. Both massed and distributed retention trials were performed on the same version of the task according to a double transfer design. The results confirmed the apparent disparity: Acquisition and retention were facilitated by distributed practice on the continuous task, but by massed practice on the discrete task. These results were discussed in terms of the role of the inter-trial interval in discrete and continuous tasks.     

Examination of the psychometric properties of the Perceived Motivational Climate in Sport Questionnaire - 2 in a sample of female athletes

We undertook two studies to determine the validity and reliability of the revised Perceived Motivational Climate in Sport Questionnaire (PMCSQ-2). In Study 1, 201 female athletes (mean age 16.4 years) were administered the initial version of the PMCSQ-2 and a measure of reported tension and pressure experienced in sport. Exploratory principal component analysis suggested that the PMCSQ-2 contained two higher-order scales (Task-Involving and Ego-Involving climates), each with three subscales (Task: Cooperative Learning, Effort/Improvement, Important Role; Ego: Intra-Team Member Rivalry, Unequal Recognition, Punishment for Mistakes). In Study 2, 385 female volleyball players (mean age 15.2 years) completed the PMCSQ-2, the Intrinsic Motivation Inventory and a measure of Team Satisfaction. Confirmatory factor analysis was applied to six competing models. The oblique six-factor model and oblique hierarchical model provided comparable fit to the data. Acceptable fit was reached based on model respecification. Across Studies 1 and 2, internal consistency was found to be acceptable for the higher-order scales and subscales (with the exception of the Intra-Team Member Rivalry subscale). We found evidence for the concurrent validity of the instrument.     

Buoyancy of College Women as Predicted by Certain Anthropometric Measures

Abstract

A discriminant analysis equation was computed to predict buoyancy from 17 anthropometric variables. The subjects for the study were 74 Caucasian women and 81 Negro women university students. The Negro group had less buoyancy and was the only group for which it was possible to compute a discriminant equation as the Caucasian group did not have any nonfloaters.     

Women's Participation in Sport in Portugal during the New State Regime

The period of Portuguese history known as the New State (1930–1974) was marked by a strong ideology that had a great impact upon gender relations and on women's status and their participation in sport. During this period a variety of arguments grounded in aesthetics, morals, health and women's biology were put forward not only to encourage women's involvement in sport but also to control the kinds of sports in which women could be involved, as well as the intensity of sports practice. In spite of the state's attempt to control women's involvement in sport, there were women who resisted this control by pursuing sport, thus showing the existence of spaces within the sports figuration that were used to express ideas different from those disseminated by the regime. In this context the campaign for women's sport, which developed in the 1930s, was important. This paper seeks to examine women's participation in sport and in particular in all-female sports clubs and the controversies that surrounded the campaign for women's sport and the creation of such clubs.     

A Consideration of Qualities Used by Administrators in Judging Effective Teachers of Physical Education in Minnesota

Abstract

The relationships between selected personality and motor variables in emotionally disturbed children were investigated in 61 male and female children, ages 6 to 13, in residential Re-Ed schools. In addition, reliability estimates were obtained for certain measuring instruments with this special group of subjects. The results revealed that (a) selected personality and motor variables appeared essentially unrelated; (b) grip strength, 50-yd dash, and flexed-arm hang were reliable while sit-ups and 600-yd run-walk were moderately reliable; (c) the arm and leg coordination measures, the four second-order factors of the Children's Personality Questionnaire (CPQ) and Early School Personality Questionnaire (ESPQ), the Self-Esteem Scale, the Body Cathexis Scale, and the Body Cathexis-Short Form all exhibited moderate reliabilities; and (d) the 14 primary factors of the CPQ and ESPQ generally exhibited lower reliabilities.     

Generation Psy: Student characteristics and academic achievement in a three-year problem-based learning bachelor program

This study investigated the simultaneous impact of demographic, personality, intelligence, and (prior) study performance factors on students' academic achievement in a three-year academic problem-based psychology program. Information regarding students' gender, age, nationality, pre-university education, high school grades, Big Five personality traits, intelligence (i.e., numerical, verbal, spatial), observed learning activities, and self-study time was collected among almost 1800 students enrolled in this psychology bachelor program at Erasmus University Rotterdam between 2003 and 2009. Academic achievement was measured by students' yearly number of acquired credit points, a course test, and a knowledge progress test. Multiple regression analyses showed that observed learning activities, first- and second-year performance, high school grades, conscientiousness, and verbal ability were most strongly and consistently related to academic achievement in the bachelor. Other student factors also contributed to academic achievement, but their influence was less prominent and mainly restricted to the first year. These results suggest that (prior) educational achievements and observable learning activities are most important for academic success in a problem-based learning bachelor program.     

Psychometric evaluation of the exercise identity scale among Greek adults and cross-cultural validity

The present study reported on translating the Exercise Identity Scale (EIS: Anderson & Cychosz, 1994) into Greek and examining its psychometric properties and cross-cultural validity based on U.S. individuals' EIS responses. Using four samples comprising 33, 103, and 647 Greek individuals, including exercisers and nonexercisers, and a similar sample comprising 800 U.S. individuals, the concurrent validity, factor structure, internal reliability, test-retest reliability, external validity, gender invariance, and cross-cultural validity of the EIS responses were examined using confirmatory factor analytical procedures. The results supported the concurrent validity, an adequate unidimensional factor structure for the translated EIS and the internal reliability and test-retest reliability over a 6-week interval. Further, cross-gender configural, partial metric, partial strong factorial, and partial strict factorial invariance and cross-cultural configural and partial metric invariance supported the cross-cultural equivalence of the EIS versions. Moreover, the external validity of the translated EIS responses was also supported. Overall, the findings supported the validity of the exercise identity construct outside North American boundaries and the EIS items' equivalence, providing initial evidence for its cross-cultural applicability.     

The role of preparatory heart rate deceleration on balance beam performance

Preparatory heart rate deceleration occurs in tasks with an external focus of attention and is often assumed to facilitate balance performance. However, its effects upon sport-related complex balance movements have not been studied. Heart rate patterns during the preparation period of an acrobatic element (flic-flac) on the balance beam were studied in 14 female gymnasts (M age 13.2 years). A significant heart rate deceleration was found in attempts with a fall in the consecutive acrobatic element, but not in attempts without a fall. These data suggest that preparatory heart rate deceleration may be detrimental to the performance of complex movements on the balance beam.
