The purpose of the present study was to test the effectiveness of a 10-week self-talk intervention on competitive performance in young swimmers. Participants were 41 swimmers (M age 14.59, SD = 1.58 years), whose performance was recorded on 2 competitive occasions with a 10-week interval. In-between the 2 competitions, participants in the intervention group followed a self-talk training program. The results showed that the intervention group had greater performance improvements than the control group, thus, supporting the effectiveness of the program in enhancing sport performance in a competitive environment. The findings provide directions for the development of effective self-talk interventions.  相似文献

Effect of imagined movement speed on subsequent motor performance   总被引:2,自引:0,他引:2  
Researchers realize that motor imagery (MI) duration is closely linked to actual motor action duration. In 2 experiments, the authors investigated the effect of changing MI speed on actual movement duration over a 3-week training period. Experiment 1 involved 2 series of body movements that 24 participants mentally performed faster or slower than their actual execution speeds. The fast MI group's actual times decreased on subsequent performance. Participants in Experiment 2 were 21 skilled athletes who increased (decreased) their well-rehearsed actual movement times after MI training at a slow (fast) speed. The effect was task-related, however: MI affected only self-initiated movement. The effect of MI on actual speed execution supports the ideomotor theory because anticipation of sensory consequences of actions is mentally represented.  相似文献

Imagery can improve sport performance, although its efficacy is mediated by the ease with which athletes can generate images. Establishing techniques that improve this imagery ability factor is desirable to enhance the effectiveness of imagery interventions. Twenty-seven club-level female golfers were assigned to imagery, action observation, or physical practice training groups (n = 9). Changes in image generation ease were assessed using the Revised Movement Imagery Questionnaire over an 8-week period. Imagery and action observation training were both effective in improving aspects of imagery ability. Action observation can provide sport psychologists with an effective tool for improving visual imagery ability in athletes.  相似文献

In order to improve the spelling performance of high school students with deficits in written expression, an error self-correction procedure was implemented. The participants were two tenth-grade students and one twelfth-grade student in a program for individuals with learning disabilities. Using an alternating treatments design, the effect of error self-correction was compared with a more traditional method of spelling practice. The intervention and follow-up phases were implemented over a 6-week period with maintenance checks conducted 4 and 8 weeks after the termination of instruction. Results indicated that the error self-correction procedure was superior to the traditional method of review during the intervention and follow-up phases, but some gains were lost during the maintenance phase.  相似文献

Little research has examined how imagery effects learners' acquisition of motor tasks requiring coincident anticipation timing (CAT). CAT is a fundamental component of hitting, passing, and receiving required in several sports. The purpose of the current study was to examine the effects of a PETTLEP imagery intervention on learners' CAT performance using a Bassin Anticipation Timer. Fifty-six participants (M = 20.61 years, SD = 2.48) were randomly assigned into one of four training groups: physical practice (PP), imagery practice (IP), imagery practice + physical practice (IP +PP), or a control (CON) group. The study consisted of three phases: pretest, intervention, and a posttest. Results revealed that the PP and IP+PP groups had significantly lower absolute timing error compared to the CON group on the posttest. The IP+PP group was the only group to have lower variable error compared to the CON group on the posttest. Results extend prior research by demonstrating that imagery combined with physical practice can benefit the learning of a CAT task and that imagery alone may not assist learners in acquiring tasks requiring CAT. Results are congruent with prior research demonstrating that imagery is most effective when combined with physical practice.  相似文献

A coaching strategy to decrease errors in swimming strokes with swimmers who had not improved under "standard" coaching procedures was investigated using a multiple baseline design across subjects and swimming strokes. The procedure resulted in a large decrease in errors on swimming strokes during sessions in a training pool. Stimulus generalization of improved performance to normal practice conditions in the regular pool was observed with all but one swimmer. This improvement was maintained during two maintenance phases lasting approximately 2 weeks, as well as under standard coaching conditions during at least a 2-week follow-up. For two swimmers, error rates on one of the strokes showed a gradual increase between the third and fifth week of follow-up, but brief remedial prompting sessions immediately corrected their performance. Some beneficial response generalization to other components of the stroke being trained was observed, but no improvements were found on untrained strokes. The error correction package did not disrupt practice, require excessive amounts of the coach's time, or necessitate the use of cumbersome apparatus. In addition, the coach and the swimmers considered the procedures to be effective, and expressed their willingness to participate in them again in the future.  相似文献

The effects of a systematic cognitive-behavioral intervention program were examined upon the further appraisals (i.e., emotional orientation) of four golfers who interpreted their emotions as debilitative towards upcoming performance and the subsequent effect on actual performance. A systematic, theoretically underpinned, multiple-baseline single-subject design was employed, with four main phases adopted over a 34-week period: Phase I involved baseline monitoring of emotion and performance data; Phase II included the education and acquisition of the cognitive-behavioral technique; Phase III entailed the integration of technique within actual competitive performance; an immediate and 3-month post intervention phase was incorporated for social validation data. An instant intervention effect on emotional orientation was observed with interpretations changing from debilitative to facilitative or unimportant. Improved and more consistent subjective and objective performances were also reported. Social validation during (open-ended questionnaires) and post-intervention (interviews) indicated changes in performers’ focus from their emotions and negative thoughts towards the task in hand. Indeed, the intervention was suggested to promote a change in focus to play the best shot possible and confidence to perform during problem holes.  相似文献

Football players adapt their movements to opportunities within the surrounding environment by engaging in visual exploratory activity (VEA) to pick up information. This study adds to the extant literature by using a 6-week PETTLEP imagery intervention to train VEA and improve performance with the ball. A single-case, multiple baseline across participants' design was conducted with 5 elite academy football players. Results indicated that a PETTLEP imagery intervention improved VEA, particularly in center midfielders. In addition, indications of improvements in performance with the ball were present within some participants. Future researchers could examine the processes underpinning VEA to enhance applied interventions for this skill.  相似文献

Two studies examined the effects of PETTLEP-based imagery compared to more traditional imagery interventions. PETTLEP imagery aims to produce a realistic and more functionally equivalent imagery experience than traditional imagery methods through factors such as wearing the correct clothing or imaging in the correct environment. In Study 1, 48 varsity hockey players were divided into four groups: “Sport-specific” imagery, “clothing” imagery, “traditional” imagery, and control. Imagery participants imaged 10 penalty flicks daily for six weeks, and controls spent an equivalent time reading hockey literature. In the post-test, the sport-specific group scored significantly higher than the clothing group, who scored significantly higher than the traditional imagery group. In Study 2, 40 junior gymnasts attempted a turning jump on the beam. They were split into four groups: A physical practice group, a PETTLEP imagery group, a stimulus only imagery group, and a control (stretching) group. Each group performed their task three times per week for six weeks. Both the physical practice and PETTLEP groups improved significantly from pre-test to post-test, with no significant difference between them, but the stimulus and control groups did not improve significantly. Taken together the results from Study 1 and 2 provide support for the efficacy of PETTLEP-based imagery over more traditional imagery interventions.  相似文献

Using 192 paid participants who trained on a command-and-control microworld simulation, we examined the comparative effectiveness of two distributed practice schedules in enhancing performance at the end of training as well as after an 8-week nonuse period. Longer interstudy intervals (10 hr of practice over 2 weeks) led to higher levels of skill at the end of training and after nonuse than shorter interstudy intervals (10 hr of practice over 1 week). The study begins to address gaps in the skill retention literature by using a cognitively complex task and an extended nonuse interval. The primary implication of our findings is that scheduling longer interstudy practice intervals is a viable means of enhancing immediate posttraining performance and promoting long-term skill retention for cognitively complex tasks.  相似文献

Imagery intervention in open and closed tennis motor skill performance   总被引:1,自引:0,他引:1  
To assess use of imagery intervention in performance of two tennis motor skills the quasi-experimental design included a pre- and posttest and a control group. The tennis service shot and service receiving skill were selected as representative of open and closed skills, respectively. 48 subjects, male tennis players, whose ages ranged from 16 to 18 yr. (M = 17.2), were divided into two groups: (1) Technical practice only which was used as control group and (2) Imagery group who received both imagery and technical practice. Analysis of covariance showed a significant main effect for the imagery intervention on the closed skill (p = .002). Findings suggest that imaging a positive outcome may be more powerful in improving performance of closed skill movements than of open skill movements.  相似文献

Discrimination of blood pressure in the natural environment as a function of feedback was assessed. Seventeen normotensives screened for blood pressure lability were randomly assigned to two groups. These subjects were then asked to estimate their systolic and diastolic blood pressure values two times per day over a 4-week period. Feedback for accuracy of blood pressure discriminations was implemented across the two groups in a multiple baseline fashion, using a feedback withdrawal condition in Group I to assess maintenance effects over time. Results showed improvement in discrimination accuracy for subjects in both groups when feedback was used, and no decrement in performance over a 2-week period after feedback was removed for subjects in Group I. Discrimination of systolic pressures improved at a slightly faster rate than discrimination of diastolic pressures.  相似文献

The current quasi-experiment examined changes in youth baseball players’ (N = 9) swing performance following an imagery intervention. Athletes participated in one of three conditions, each of which employed a different combination of slow-motion (SM), real-time (RT), or fast-motion (FM) image speeds: SM?+?RT, RT?+?FM, or SM?+?RT?+?FM. A single-subject multiple-baseline design was employed. The intervention approximated the real-world environment in which baseball players practice, thus, increasing representative design. Results generally indicated positive changes across all three conditions, however, the SM?+?RT?+?FM condition exhibited the most improvement. The employment of a multiple-speed imagery intervention appears to be a viable option for young athletes.

The cognitive benefits of closed-skill sports practice have so far been scantily investigated. Here, we thus focused on the potential impact of swimming and running - two sports that highly rely on a precise control of timing - on time processing. To investigate the impact of these closed-skill sports on time perception and estimation, three groups of participants (for a total of eighty-four young adults) took part in the present study: expert swimmers, expert runners, and non-athletes. The ability to process temporal information in the milliseconds and seconds range was assessed through a time reproduction and a finger-tapping tasks, while a motor imagery paradigm was adopted to assess temporal estimation of sport performance in a wider interval range. We also employed the Vividness of Movement Imagery Questionnaire to assess the individual's ability of motor imagery. Results showed that closed-skill sports, specifically time-related disciplines, enhance motor imagery and time perception abilities. Swimmers were more accurate and consistent in perceiving time when compared to runners, probably thanks to the sensory muffled environment that leads these athletes to be more focused on the perception of their internal rhythm.  相似文献

Objectives

The primary purpose of the present study was to examine the effects of a cognitive specific (CS) imagery intervention on the soccer skill performance of young athletes aged 7-14 years and determine if performance varied with age.

Design

Participants were 143 soccer athletes belonging to 16 different teams. Teams were randomly assigned to either a cognitive specific (CS) or motivational general-arousal imagery intervention.

Methods

Athletes were administered the SIQ-C and tested on the soccer skill to determine baseline performance. Following their imagery intervention, athletes were tested on the same soccer skill, and completed the SIQ-C a second time.

Results

The results indicated that only the younger athletes (7-10 years) receiving CS imagery performed faster following their intervention. Moreover, only the 7-8 year old athletes in the CS imagery condition significantly increased their use of CS imagery over time.

Conclusions

These findings suggest that young athletes who use CS imagery will benefit from a CS imagery intervention, thus implying that mental skills training should begin at a young age if athletes are to maximize the benefits of such training.  相似文献

In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice.  相似文献

Robert E. Koslow 《Sex roles》1987,17(9-10):521-527
The ability of males and females to use visual-spatial imagery as a facilitator of symbolic motor skill acquisition was investigated. Subjects, ordered by gender into control and mental imagery groups, performed 15 trials on a mirrored drawing task. The results indicated that, although both male and female mental imagery groups performed the task more skillfully than the control groups, the male mental imagery group scores over the early stages of performance were better as compared to the female mental imagery group scores. This difference was eradicated during the latter stages of performance. The findings, in addition to supporting the positive effects of mental imagery, lend support to the hypothesis that sex-related differences in selected visual-spatial tasks may be amendable through training followed by practice.  相似文献

The purpose of this study was to examine the interactive effects of dispositional mindfulness and visualized PETTLEP imagery training on basketball mid-range shooting performance and retention. Seventy-three participants (M age = 20.32 ± 1.09) with high/low dispositional mindfulness (high n = 35; low n = 38) selected out of 302 college students were randomly assigned into the following six groups: (a) high mindfulness internal imagery (H-II, n = 13); (b) high mindfulness external imagery (H-EI, n = 11); (c) high mindfulness control (H–CO, n = 11); (d) low mindfulness internal imagery (L-II, n = 13); (e) low mindfulness external imagery (L-EI, n = 12); and (f) low mindfulness control (L-CO, n = 13). Participants engaged in a pretest to measure their basketball shooting performance, then participated in a 6-week (3 times/per-week) intervention, plus a posttest and retention test. A three-way 2 (high/low mindfulness) X 3 (treatments: internal-, external imagery, and control) X 3 (measurement time: pretest, posttest, and retention) mixed ANOVA statistical analysis found dispositional mindfulness interacted with treatments and measurement time. The main effects showed high dispositional mindfulness performed better than low dispositional mindfulness, and internal imagery training performed better than external imagery training on mid-range basketball performance at retention. The 3–way interaction indicated that when using either internal or external imagery, high dispositional mindfulness performed better than low mindfulness on retention but not posttest. For 2-way interaction, high dispositional mindfulness performed better than low dispositional mindfulness on retention but not posttest. Our results extended current knowledge on sport imagery and dispositional mindfulness and gained several theoretical implications for researchers. The limitations, future research directions, and practical implications were also discussed.  相似文献
