The purpose of this investigation was to assess the effect of self-modeling on self-efficacy and performance of balance beam routines. Subjects were intermediate-level female gymnasts who were randomly assigned to one of two groups, a self-modeling or a control group. For the self-modeling group, self-modeling videotapes were made of each subject performing her balance beam routine. During a 6-wk. period, self-modeling group subjects viewed the videotape of themselves three times a week prior to practice. During this time, the control group and self-modeling group participated in their normal instructional program. All subjects completed self-efficacy inventories and balance beam skill tests at four intervals, a pretest, a 2-wk. test, a 4-wk. test, and a 6-wk. posttest. Although no significant differences in ratings of self-efficacy or balance beam performance between the groups were found, the correlation between subjects' self-rated performance scores and actual performance scores for the self-modeling group was significant (r = .92). This correlation was not significant for the control group (r = .02). This significant correlation suggests that self-modeling may enhance performers' ability to assess their own performance realistically, improving their understanding and use of instructional feedback to enhance performance.
本研究的目的是评估自我示范对平衡木动作自我效能感和表现的影响。研究对象是中级水平的女子体操运动员,她们被随机分配到两组之一,即自我示范组或对照组。对于自我示范组,为每个受试者制作了她们进行平衡木动作的自我示范录像带。在为期6周的时间里,自我示范组的受试者在每次练习前一周观看三次自己的录像带。在此期间,对照组和自我示范组参与他们正常的教学计划。所有受试者在四个时间点完成自我效能感量表和平衡木技能测试,即前测、2周测试、4周测试和6周后测。尽管两组之间在自我效能感评分或平衡木表现上未发现显著差异,但自我示范组受试者的自我评定表现得分与实际表现得分之间的相关性显著(r = 0.92)。对照组的这一相关性不显著(r = 0.02)。这一显著相关性表明,自我示范可能会增强表演者现实地评估自身表现的能力,提高他们对教学反馈的理解和运用,从而提升表现。
