Effects of Competition,Success/Failure,and Sex on Intrinsic Motivation

The purpose of the present investigation was to determine the effect of different types of competition and success/failure on intrinsic motivation of males and females performing on a motor task. Subjects were randomly assigned to one of the following competition conditions: (a) face-to-face competition, (b) competition against a standard of excellence, or (c) a noncompetitive condition (control). In addition, subjects received either success or failure feedback while performing on the pursuit rotor. Results indicated that subjects receiving success exhibited more intrinsic motivation than subjects receiving failure. Subjects also displayed more intrinsic motivation during competition than when not in competition. In addition, the Sex × Competition interaction indicated that males exhibited more intrinsic motivation when competing than when not competing, whereas females displayed no differences between these conditions. Results are discussed in light of previous research by Deci (1975) and Deaux (1977) and future direction is offered.

Youth Fitness Testing: The Effect of Percentile-Based Evaluative Feedback on Intrinsic Motivation

Abstract

This study was a test of Deci and Ryan's (1985) cognitive evaluation theory in a fitness testing situation. More specifically, it was a test of Proposition 2 of that theory, which posits that external events that increase or decrease perceived competence will increase or decrease intrinsic motivation. Seventh and eighth grade schoolchildren (N = 105) volunteered for an experiment that was ostensibly to collect data on a new youth fitness test (the Illinois Agility Run). After two untimed practice runs, a specially adapted version of the Intrinsic Motivation Inventory (IMI) was administered as a pretest of intrinsic motivation. Two weeks later when subjects ran again, they were apparently electronically timed. In reality, the subjects were given bogus feedback. Subjects in a positive feedback condition were told their scores were above the 80th percentile, while those in a negative feedback condition were told their scores were below the 20th percentile. Those in a control condition received no feedback. The IMI was again administered to the subjects after their runs. Multivariate and subsequent univariate tests were significant for all four subscale dependent variables (perceived interest-enjoyment, competence, effort, and pressure-tension). Positive feedback enhanced all aspects of intrinsic motivation, whereas negative feedback decreased them. In a further test of cognitive evaluation theory, path analysis results supported the prediction that perceived competence would mediate changes in the other IMI subscales. Taken together, these results clearly support cognitive evaluation theory and also may have important implications regarding motivation for those who administer youth fitness tests.     

Effects of Curricular Activity on Students' Situational Motivation and Physical Activity Levels

Abstract

The purpose of this study was to examine (a) the effects of three curricular activities on students' situational motivation (intrinsic motivation [IM], identified regulation [IR], external regulation, and amotivation [AM]) and physical activity (PA) levels, and (b) the predictive strength of situational motivation to PA levels. Four hundred twelve students in grades 7–9 participated in three activities (cardiovascular fitness, ultimate football, and Dance Dance Revolution [DDR]) in physical education. ActiGraph GT1M accelerometers were used to measure students' PA levels for three classes for each activity. Students also completed a Situational Motivation Scale (Guay, Vallerand, & Blanchard, 2000) at the end of each class. Multivariate analysis of variance revealed that students spent significantly higher percentages of time in moderate-to-vigorous PA (MVPA) in fitness and football classes than they did in DDR class. Students reported higher IM and IR toward fitness than DDR. They also scored higher in IR toward fitness than football. In contrast, students displayed significantly lower AM toward fitness than football and DDR. Hierarchical Linear Modeling revealed that IM was the only positive predictor for time in MVPA (p = .02), whereas AM was the negative predictor (p < .01). The findings are discussed in regard to the implications for educational practice.

采用单维简单和两维复杂电脑追踪任务,探讨任务复杂程度对反馈频率适宜值的影响.96名右利手的在校大学生随机分为简单任务和复杂任务组(每组男、女各24名).两组受试者分别在25%相对频率(提供反馈的练习次数占总练习次数的25%,简称反馈频率,下同)、50%反馈频率、75%反馈频率、100%反馈频率条件下,连续两天练习简单或复杂任务,每天练习36次.第2天练习结束后休息10min,2组受试者进行无反馈保持测试.一天后,再进行无反馈的保持测试.结果显示:(1)练习阶段,两组受试者的操作绩效随反馈频率增加呈提高趋势;(2)50%反馈频率利于简单任务的技能学习,75%反馈频率利于复杂任务的技能学习;(3)任务复杂程度与反馈频率适宜值存在交互作用,与简单任务相比,操作复杂任务时,应增加反馈的频率.以上结果提示:当信息加工负荷较小(如操作任务较简单)时,减少反馈频率利于技能学习;而当信息加工负荷较大(操作任务较复杂)时,频繁反馈利于技能学习.     

Revisiting the Development of Time Sharing Using a Dual Motor Task Performance

Abstract

The purpose of the study was to investigate the effect of a 2-min. isometric exercise training program on force and fatigue in a skeletal muscle. The subjects (N=60) were divided into two equal groups, control and experimental. The control group was tested twice, once at the beginning of the experiment and again after 20 days. The subjects in the experimental group were tested before embarked on a 20-day period of isometric training. held the tension for 2 min. in the morning and again in the afternoon. Periodic tests were on the 5th, 10th, 15th, and 20th days. Large gains of initial strength were recorded on the 5th day. Isometric training continued beyond five days produced no significant gains in initial strength althoughe was a significant increase in isometric endurance. Isometric exercise continued longer than 15 days resulted in a significant decrease in initial strength and isometric endurance.     

Comparison of Postperformance State Anxiety of Internals and Externals Following Failure or Success on a Simple Motor Task

Abstract

The purpose of this study was twofold: (a) to determine the effect of locus of control (internal-external), success-failure, and trait anxiety (A-trait) on the perception of threat to self following competitive motor performance, as measured by postperformance state anxiety (A-state); and (b) to examine effects of success-failure relative to locus of control, as measured by self-protective answers on a postperformance attribution questionnaire. In addition, postperformance A-state relative to number of internal attributions was investigated. Two groups of subjects (N = 32) satisfying the criteria for internal-external control were subdivided by sex and randomly assigned to success-failure conditions. A-trait and preperformance A-state were assessed by the Spielberger State-Trait Anxiety Inventory (STAI) prior to the experimental treatment, and A-state measurement was repeated following the experimental treatment. Multivariate analysis of covariance revealed significant interaction effects of success-failure and locus of control relative to postperformance A-state. Univariate ANOVA revealed that externals were significantly higher on A-trait than internals. Regression analyses showed significant relationships for A-trait and pre- and postperformance A-state, as well as for relationship of postperformance A-state to number of internal attributions.

The Influence of Feedback on Competence,Motivation, Vitality,and Performance in a Throwing Task

Purpose: The purpose of this work is focused on the study of the effect that feedback has on competence valuation, perceived competence, autonomous motivation, vitality, and performance in a throwing task. Method: Thirty-five college students (26 men and 9 women), without previous experience in the task, participated in this study. The students were randomly assigned to three experimental conditions (positive, negative, and lack of feedback). Results: The results of this study point out that only those who received positive feedback before the handball throwing task, in contrast to those who received negative feedback or did not receive any feedback, showed increased levels of competence valuation (p < .05, Cliff’s delta effect size = ?.30), perceived competence (p < .001, Cliff’s delta effect size = ?.77), and autonomous motivation (p < .05, Cliff’s delta effect size = ?.48). This group also presented higher levels of perceived competence (p < .001, Cliff’s delta effect size = ?.84) and subjective vitality (p < .001, Cliff’s delta effect size = ?.80) than the group who received negative feedback after the throwing task. Those who received positive feedback also showed a higher throwing speed at the end of task than those who received negative feedback (p < 0.001, Cliff’s delta effect size = ?.71) or than those who did not receive any feedback (p < .05, Cliff’s delta effect size = ?.56). Conclusions: Competence valuation, perceived competence, autonomous motivation, subjective vitality, and throwing speed were favorably influenced by positive feedback. These results have important implications for the training style applied by coaches.     

Competition and Instructional Set Effects On the Speed and Accuracy of a Throwing Task

Abstract

Two experiments were conducted to investigate the effects of competition and instructional sets on the speed and accuracy of a dart-throwing task. In both experiments individuals competed against another subject on one day, and performed under noncompetitive conditions on a second day. The five distinct instructional sets varied from extreme emphasis on speed to extreme emphasis on accuracy. Multivariate analyses of variance revealed main effects for instructional sets on speed and accuracy in both experiments. Strong tradeoffs occurred with speed slowing and accuracy improving as the instructional emphasis changed from speed to accuracy. A competition by instructional sets interaction in Experiment 2 indicated that competition facilitated speed when speed was important, but when instructions emphasized accuracy, speed was slower in competition than in noncompetition. Accuracy was not affected by competition.

Effects of Extended Practice and Movement Time on Motor Control of a Coincident Timing Task

Abstract

The present study investigated the extent to which movement time (MT) and practice influenced subjects' use of feedback to make corrections in the spatial-temporal movement pattern of coincident timing responses. Subjects performed 400 coincident timing responses of either 250,500, or 1,000 milliseconds. Schmidt's (1972) index of preprograming (IP) was used to estimate the level of feedback involvement in controlling the movement while the spatial-temporal pattern of the response was characterized by fluctuations in the speed of the movement to the barrier. The analysis of the IP and the spatial-temporal pattern of the responses suggest that MT and not practice limits the extent to which a response is preprogramed, with rapid performance more likely to be preprogramed than slower performance. Indeed, in the 1,000-millisecond response, the movement pattern appeared to be adjusted in the terminal phase (i.e., near the barrier) by accelerating or decelerating the rate of movement.     

运动终板的分型及运动训练对运动终板的影响

运动终板在骨骼肌纤维上的分配是骨骼肌神经支配的表现形式,运动终板的形态结构和机能状态直接影响到肌肉的功能。它既是神经系统引起肌肉收缩的关键部位,也是肌肉疲劳的潜在衰竭点。通常,骨骼肌纤维形态改变的同时伴有运动终板形态结构的变化。因此,在运动训练条件下对运动终板的形态学研究,为加快骨骼肌纤维的收缩效率和提高运动员的成绩提供良好的理论依据。
