Objective

The purpose of this study was to compare the coach–athlete interaction structures of two competitive youth synchronized swimming teams differentiated on the basis of level of success.

Design

This comparison was a pilot test of the state space grid (SSG) observational methodology (Hollenstein, 2007) in sport settings.

Method

Two teams (two head coaches and 17 athletes in total) were observed over five training sessions. Coach and athlete behaviour was coded continuously for the duration of each training session. Measures of coach–athlete interaction were derived from these coded behaviours and compared between teams.

Results

Results revealed significant differences between the teams on measures of interaction variability, behavioural content patterns, and the sequencing of coach behaviours. The more successful team was characterized by less variable, more patterned interactions between coaches and athletes. The sequencing of coach behaviours for the more successful team emphasized the pairing of technical correction and positive reinforcement.

Conclusions

The findings suggest that positive environments characterized by a deliberate pattern of coach–athlete interaction may be associated with youth sport settings producing more satisfied and successful athletes. These results support the utility of SSGs for the analysis of interpersonal interactions in sport and highlight the unique insights made available through use of this methodology.  相似文献

Young (<36 years) and older (>59) adults viewed videos in which the same individual committed a faux pas, or acted appropriately, toward his coworkers. Older participants did not discriminate appropriate and inappropriate behaviors as well as young participants. Older participants also scored lower than young participants on an extensive battery of emotion recognition tests, and emotion performance fully mediated age differences in faux pas discrimination. The results provide further evidence for the role of emotion perception in a range of important social deficits.  相似文献

Contrary to longstanding opinion, Descartes does not deny all feeling and awareness to non‐human animals. Though he undoubtedly denies that animals think, a case can be made that he nonetheless would allow them organism consciousness, perceptual consciousness, access consciousness and even phenomenal consciousness. Descartes does not employ or accept an ‘all‐or‐nothing’ view of consciousness. He merely denies (not that this is a small thing) that animals have the capacity for self‐conscious reflective reception or awareness of sensations and feelings.  相似文献

Mobile phone usage is now at saturation point in most Western countries. The current research investigated the usability of services provided by a mobile phone network, specifically whether two different forms (text, graphic) of an advance organizer (AO) assisted novice users in applying information supplied in a manual. It was hypothesized that a graphic AO would facilitate the development of coherent mental models of the network to enhance task performance, and that lower ability groups in particular would benefit from AOs. Contrary to prediction, the text AO group outperformed both the graphic AO and control groups. Lower ability groups also benefited more from a text AO than a graphic AO.

Alcohol seeking by rats: Action or habit?   总被引:5,自引:0,他引:5  
In two experiments, we examined the relative susceptibility to outcome devaluation of lever pressing by rats for either a 10% ethanol solution or food pellets. The rats were trained to press different levers for these two reinforcers using a sucrose-substitution procedure. An aversion was then conditioned from either the ethanol solution or the food pellets by pairing consumption with illness induced by lithium chloride. When instrumental performance was subsequently tested in extinction, the rats pressed less on the pellet lever if the pellets, rather than the ethanol, had been devalued by aversion conditioning. By contrast, performance on the ethanol lever was unaffected by whether the ethanol or pellets were devalued. Moreover, noncontingent presentations of the devalued reinforcer had no impact on test performance. The differential resistance to outcome devaluation suggests that, in contrast to food seeking, alcohol seeking is a stimulus-response habit rather than a goal-directed action mediated by a representation of the action-outcome contingency.  相似文献

In this paper we report a partial replication of the finding that women face a double-bind with respect to emotional expression (Kelly & Hutson-Comeaux, 2000) and explore the hypothesis that gender-inconsistent emotional reactions are perceived to be more valid indicators of one's underlying emotional experience than gender-consistent emotional reactions. Men and women evaluated the appropriateness and sincerity of women's and men's overreactions to happy and angry events in both interpersonal and achievement contexts. Women's overreactions to happy events were judged as less appropriate and their emotional reactions were perceived as less sincere than were men's, particularly in an interpersonal context. In addition, men's overreactions to angry events in the interpersonal context were judged as less appropriate and less sincere than were women's. Implications of the findings for other types of social judgments are discussed.  相似文献

The courts assume that jury deliberation corrects errors in jurors' memories, so that the verdict is based on accurate memory for the trial. We evaluated the validity of this assumption by examining jurors' memories and verdicts both before and after deliberation. Unlike previous studies, we tracked how event memories changed as a function of how they were discussed in deliberation. Overall, deliberation resulted in only a slight memory improvement. Deliberation corrected errors and did not introduce distortions. Reasons for such slight memory improvement are that jurors did not think they had memory gaps and thus did not use the deliberation process to improve their memory, and jurors who controlled deliberation were not always the most accurate in their memories. Finally, those most likely to change their verdict as a result of deliberation were not those who had the least accurate memories, but rather those who had the least confidence in their memories.

In the present research, we asked whether pigeons tended to judge time intervals not only in terms of their absolute value but also relative to a duration from which they must be discriminated (i.e., longer or shorter). Pigeons were trained on two independent temporal discriminations. In one discrimination, sample durations of 2 and 8 sec were associated with, for example, red and green hue comparisons, respectively, and in the other discrimination, sample durations of 4 and 16 sec were associated with vertical and horizontal line comparisons, respectively. If pigeons are trained on a temporal discrimination and tested with intermediate durations, the subjective midpoint typically occurs close to the geometric mean of the two trained values. The 4- and 8-sec values were selected to be the geometric mean of the two values in the other discrimination. When a 4-sec test sample was presented with the comparisons from the 2- and 8-sec discrimination, the pigeons preferred the comparison associated with the shorter sample. Similarly, when an 8-sec test sample was presented with the comparisons from the 4-and 16-sec discrimination, the pigeons preferred the comparison associated with the longer sample. Thus, a relative grouping effect was found. That is, durations that should have produced indifferent choice were influenced by their relative durations (shorter than or longer than the alternative) during training.  相似文献
