Psychological need-satisfaction,and basketball performance

ObjectivesWe applied self-determination theory (Deci & Ryan, 2000) to examine whether pre-game psychological need-satisfaction predicts the quality of sports performance, and whether performance, in turn, predicts post-game need-satisfaction.Design/methodUndergraduate participants competing in a recreational league basketball season completed autonomy, competence, and relatedness need-satisfaction measures before and after games (N = 150 person-games). For each game, data were collected on the number of one, two, and three point shots taken, as well as shooting percentages for each type of shot.ResultsParticipants with greater pre-game autonomy performed best overall during games, although this pattern did not emerge within-subjects. Good game performance predicted enhanced post-game relatedness and competence, both between- and within-subjects.ConclusionImplications for optimal sports performance are considered.     

Emotion in man as Tested by the Delta Index of the Electroencephalogram: II. Simultaneous Records from Cortex and from a Region Near the Hypothalamus

Five male undergraduates could earn 4¢ for every 200 knob-pulls. In addition, they could avoid or terminate an aversive tone by pressing a button with a force of 1.5 lbs (nonaggressive response) or by hitting a cushion with at least 20 lbs force (aggressive response). Rates of aggression tended to be higher during sessions where money was taken from the Ss at the rate of 1¢ per 12 seconds than during sessions when taking was not in effect. Rates of nonaggressive responses were constant across conditions.     

Coordination Dynamics of the Horse-Rider System

The authors studied the interaction between rider and horse by measuring their ensemble motions in a trot sequence, comparing 1 expert and 1 novice rider. Whereas the novice's movements displayed transient departures from phase synchrony, the expert's motions were continuously phase-matched with those of the horse. The tight ensemble synchrony between the expert and the horse was accompanied by an increase in the temporal regularity of the oscillations of the trunk of the horse. Observed differences between expert and novice riders indicated that phase synchronization is by no means perfect but requires extended practice. Points of contact between horse and rider may haptically convey effective communication between them.     

A systematic review of studies comparing body image concerns among female college athletes and non-athletes, 1997–2012

Research prior to 2001 indicated that athletes experienced better body image than non-athletes, with no differences among sport types. Since then, female athletes have become increasingly sexually objectified in the media, and the sociocultural beauty ideal has shifted to emphasize appearing both athletic and thin. Part I of this paper explores the literature describing these changes. Part II presents a systematic and comprehensive literature review of 10 recent studies comparing body image concerns (BIC) among collegiate female athletes and non-athletes to identify the current status of BIC in female athletes. Findings indicate that involvement in collegiate athletics provides some protection from BIC; however, this protection appears attenuated for athletes in more feminine sports (e.g., gymnastics), and higher level athletes (Division I). Researchers should examine how sociocultural pressures unrelated to competition predict female athletes’ BIC using measures that focus on objectification, positive body image, body functionality, and thin- and athletic-ideal internalization.     

Intelligence,Practice and Virtue: A Critical Review of the Educational Benefits of Expertise in Physical Education and Sport

The paper calls for a re-evaluation of physical education’s cognitive value claims, as this issue is fundamental to many of the conceptual difficulties the subject faces. Current epistemological challenges are reviewed before analysing the structural connections between intelligent practice and intelligent virtues, and the possibilities for physical education to better articulate its’ intrinsic and instrumental values claims. The paper evaluates arguments made on this basis and reviews revised curriculum planning and pedagogical practices, which could support an enhanced focus on learners’ wider aspirations and achievements; factors crucial for a virtuous life. While applauding enquiry into the possibilities for considering physical education as a moral endeavor, the paper raises concerns about conceptual clarity in intellectual and empirical accounts of virtue. The paper concludes by advocating further research on the interrelationship between intellectual and empirical accounts of skill, evaluation of learners’ decision-making and the aims of physical education and school sport programmes.     

The role of delight in driving repurchase intentions

A channel differentiator for brick-and-mortar retail stores is the availability of salespeople to assist customers directly in their purchase decision. This research considers two aspects of customer interactions with retail salespeople that lead to perceptions of extraordinary service and enhance repurchase intentions: customer comfort and salesperson expertise. Retail customers desire value-added informational assistance from the salesperson to minimize ambiguity associated with the product and to reduce the risk associated with a purchase decision. A retail salesperson needs to make customers feel comfortable so that the customer will share specific needs during the interaction, and the salesperson can recommend appropriate products and services. Our findings reveal that while both customer comfort and salesperson expertise positively influence satisfaction with the salesperson and customer delight, only customer delight leads to repurchase intentions. While satisfaction is a commonly asserted goal for retailers; the present research suggests that in a transaction-based environment, elevated emotions such as customer delight represent a more powerful predictor of repurchase intentions. This research provides evidence of trainable salesperson behaviors that enhance customer perceptions of extraordinary service and offer firms an opportunity for significant performance gains.     

The influence of ball-swing on the timing and coordination of a natural interceptive task

Successful interception relies on the use of perceptual information to accurately guide an efficient movement strategy that allows performers to be placed at the right place at the right time. Although previous studies have highlighted the differences in the timing and coordination of movement that underpin interceptive expertise, very little is known about how these movement patterns are adapted when intercepting targets that follow a curvilinear flight-path. The aim of this study was to examine how curvilinear ball-trajectories influence movement patterns when intercepting a fast-moving target. Movement timing and coordination was examined when four groups of cricket batters, who differed in their skill level and/or age, hit targets that followed straight or curvilinear flight-paths. The results revealed that when compared to hitting straight trials, (i) mixing straight with curvilinear trials altered movement coordination and when the ball was hit, (ii) curvilinear trajectories reduced interceptive performance and significantly delayed the timing of all kinematic moments, but there were (iii) larger decrease in performance when the ball swung away from (rather than in towards) the performer. Movement coordination differed between skill but not age groups, suggesting that skill-appropriate movement patterns that are apparent in adults may have fully emerged by late adolescence.     

Plateaus,Dips, and Leaps: Where to Look for Inventions and Discoveries During Skilled Performance

The framework of plateaus, dips, and leaps shines light on periods when individuals may be inventing new methods of skilled performance. We begin with a review of the role performance plateaus have played in (a) experimental psychology, (b) human–computer interaction, and (c) cognitive science. We then reanalyze two classic studies of individual performance to show plateaus and dips which resulted in performance leaps. For a third study, we show how the statistical methods of Changepoint Analysis plus a few simple heuristics may direct our focus to periods of performance change for individuals. For the researcher, dips become the marker of exploration where performance suffers as new methods are invented and tested. Leaps mark the implementation of a successful new method and an incremental jump above the path plotted by smooth and steady log–log performance increments. The methods developed during these dips and leaps are the key to surpassing one's teachers and acquiring extreme expertise.     

Information‐Theoretic Measures Predict the Human Judgment of Rhythm Complexity

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.     

Going for Gold: Understanding Talent Development Through the Lived Experiences of US Female Olympians

Using qualitative methods design, this research examined the talent development process of US female Olympians. In addition, models of talent development in gifted women in other domains assisted in understanding the development of talent in elite female athletes. Interpretation of the experiences of the participants indicated that the models of talent development for gifted women contribute to an understanding of female athletic talent development. Yet, models presented in both sport and other professional domains do not capture all aspects of talent development as lived by the participants in this project. Within current models of talent development for athletes there is no discussion regarding what occurs after an athlete reaches the elite level of participation. A more fully integrated model of talent development must also include the contributions of athletic talent development toward development as fully actualized human beings. The participants in this research acknowledged significant development that occurred following their elite level of participation.
