The purpose of this experiment was to determine whether the open feedback system used in synchronized swimming (i.e., the judges hear and see each others’ scores after having rated each performance) leads to unwanted (i.e., nonperformance-based) conformity in the scoring by judges. Twenty judges in synchronized swimming were randomly divided into four panels of five judges. They had to rate 60 performances of the same imposed figure, the barracuda twirl: 30 performances in Phase 1 and 30 in Phase 2. Two independent variables were orthogonally manipulated: feedback (or none) during Phase 1 and feedback (or none) during Phase 2. In line with the hypotheses, the variation of scores given in Phase 1 was significantly smaller when the judges had received feedback than when they had not received feedback. Moreover, the variation of the scores given in Phase 2 remained significantly smaller among the judges who had received feedback in Phase 1 but not in Phase 2, compared with judges who had not received feedback in either phase. These results indicate that the scoring of judges in synchronized swimming is strongly and lastingly influenced by immediate feedback.

The sport literature yields little information concerning the available methods or processes coaches can use to obtain feedback about their coaching. This is unfortunate given that evaluative feedback about one’s coaching performance is useful in terms of providing direction for professional coach development (Mallett & Côté, 2006). As a follow-up to O’Boyle (2014), the purpose of this Best Practices paper is to offer a sample protocol for employing a 360-degree feedback system for coaches working in high performance settings. We draw on a review of the coach evaluation and 360-degree feedback literature, along with insights shared from Canadian intercollegiate head coaches to highlight some of the potential benefits and challenges of implementing a 360-degree feedback system in sport. We then suggest ‘best practices’ for effectively integrating this appraisal system and provide an example coach report to illustrate how feedback would be provided to a coach following a 360-degree feedback protocol. It is our hope that this sample protocol paper will encourage coaches, athletic directors, and other sport administrators to integrate comprehensive coach feedback practices in their sporting programs.

This study examined the relationship of teachers’ task refinement and feedback to the practice success of low- and high-skilled students. Data were gathered from two introductory striking units taught to fourth graders by physical education specialists. Four high- and 4 low-skilled subjects from intact classes were randomly selected in order to examine practice success when receiving refining tasks as compared to when receiving extending and applying tasks, both before and after teacher feedback. Success for low-skilled subjects remained about the same (74%) in response to both refinement and extending and applying tasks. Modest increases in success occurred when refining tasks were followed by specific feedback. High-skilled subjects’ practice success improved by 14% when they received refining tasks, as compared to when they received extending and applying tasks; however, no increase in success was experienced when teacher feedback followed refining tasks. Feedback following extending and applying tasks did result in increases in practice success for these subjects.

This study represents a descriptive analysis of feedback patterns and perceptual maps of experienced and inexperienced teachers. Five experienced elementary physical education teachers and 5 inexperienced teachers participated in the study. Data were collected by videotaping and audiotaping three lessons taught by each teacher. Transcripts of audiotapes were made for all verbal feedback administered by the teachers, and each unit of feedback was coded from the written transcripts using a multidimensional observation system. Following the second and third lessons, patterns in cue perception employed by teachers during feedback interaction were accessed using a stimulated recall interview and concept mapping techniques. Results indicated that inexperienced teachers did not differ from experienced teachers in their feedback structure. However, experienced teachers differed from inexperienced teachers on their perceptual patterns. Specifically, perceptual maps of experienced teachers were more complex and were organized hierarchically, whereas inexperienced teachers’ patterns tended to be sparse and hierarchically shallow.

There has been some support for the notion that the analytical skills of prospective physical education teachers can be improved through systematic training (Armstrong, 1986; Beveridge & Gangstead, 1988). The ultimate pedagogical objective of such analysis is the provision of meaningful feedback to the learner (Hoffman, 1977). The purpose of this study was to determine the effect of training in conceptual kinesiology on the feedback patterns of students engaged in physical education teacher preparation. Prior to and after 32 hours of instruction in kinesiological concepts, subjects (N=48) viewed several videotaped performances of a familiar and a novel skill and responded by providing corrective feedback as they would if the learners were present. Analysis of pretest/posttest differences indicated a significant increase in the corrective, accurate trial-specific feedback provided for both skills. Further analysis revealed that gender, major/minor status, and high school volleyball team experience were not related to feedback provision. However, feedback patterns were related to entry level and achievement level during the training course. It was concluded that training in conceptual kinesiology can enhance feedback-provision patterns during professional preparation.

Postural regulation is an important part of a variety of motor tasks, including quiet standing and locomotion. Muscle length feedback, both the autogenic length feedback arising from a muscle's own spindles, and heterogenic length feedback, arising from its agonists and antagonists, is a strong modulator of muscle force and well suited to postural maintenance. The effects of this reflex feedback on 3-D force generation and limb mechanics are not known. In this paper, we present a mechanical model for relating 3-D changes in cat hindlimb posture to changes in muscle lengths. These changes in muscle length are used to estimate changes in both intrinsic muscle force generation and muscle activation by length feedback pathways. Few muscles are found to have directly agonist mechanical actions, and most differ by more than 20°. Endpoint force fields are largely uniform across the space investigated. Both autogenic and heterogenic feedback contribute to whole limb resistance to perturbation, autogenic pathways being most dramatic. Length feedback strongly reinforced a restoring force in response to end-point displacement.

An experiment was conducted to investigate the relative merits of in vivo emotive imagery and performance feedback in enhancing self-efficacy beliefs and performance on a competitive muscular endurance task. College males (n=60) and females (n=60) were randomly assigned to one of three conditions: mastery imagery plus feedback, feedback alone, or control condition. Subjects in the imagery-plus-feedback condition were told that one of the pair (always the subject) would receive imagery exposure while the other (always the confederate) would wait outside. Subjects performed two trials against the confederate, who always won by 10 seconds. A Group x Trials interaction for self-efficacy revealed a significant increase for the imagery group after brief exposure. Also, imagery subjects had significantly higher efficacy scores than feedback alone or control subjects after each performance trial. A Group x Trials interaction for performance indicated that imagery subjects initially had significantly longer performance times than did feedback alone or control subjects. Performance feedback alone did not influence efficacy beliefs or performance.

When performing movements with different spatial trajectories in both upper limbs simultaneously, patterns of interference emerge that can be overcome with practice. Even though studies on the role of augmented feedback in motor learning have been abundant, it still remains to be discovered how overcoming such specific patterns of spatial interference can be optimized by instructional intervention. In the present study, one group acquired a bimanual movement with normal vision, whereas a second group received augmented feedback of the obtained trajectories on a computer screen in real time. Findings revealed that, relative to normal vision, the augmented feedback hampered skill learning and transfer to different environmental conditions. These observations are discussed in view of the benefits and pitfalls of augmented feedback in relation to task context and instructional condition.

The main purpose of this study was to examine the efficacy of a strategy that combined self talk and performance feedback. Therefore, three groups of adult tennis players performed a forehand groundstroke task. The first group (n = 16) applied an instructional self talk and self feedback combination, the second (n = 16) used regular instructional self talk, and the third (n = 16) performed without any specific aid. The hypothesis was that the performance and concentration scores of both self talk groups would improve from the pretest to the posttest, while the scores from the control group would remain unchanged. The analysis of variance with repeated measures confirmed this hypothesis. Further, the players who used self feedback perceived the effectiveness of their intervention to be significantly higher compared with the other intervention group. Overall, the combination of self talk and feedback seems to be an alternative to the original instructional self talk intervention.

A videotaping feedback package was developed for improving skills of youth competitive swimmers. Experiment 1 examined the videotaping package for improving freestyle and backstroke racing turns of young competitive swimmers. Positive results were obtained in a multiple-baseline design across subjects. Experiment 2 compared the videotaping feedback package to a group videotaping procedure (that the coach had been using at the time of this research) for improving freestyle swimming strokes of young competitive swimmers. The videotaping feedback package was effective whereas the group videotaping procedure had little or no effect. For most subjects in the two studies, improvements were maintained with minimal prompting and feedback under normal practice conditions. Suggestions for future research are discussed.
