体操动作技能再认的信号检测论研究

以四种不同的学习方式(视觉表象、动觉表象、视觉表象伴随言语指导、动觉表象伴随言语指导)及三种不同的实验对象(教育系学生、体育系普修体操学生、体育系专修体操学生)从体育动作技能形成的角度,以信号检测理论手段,探讨若干体操动作再认的特征。结果表明:(1)对体操动作再认的辨别力d′值随专业水平的提高而提高。(2)四种学习方式所得 d′值比较,动觉表象学习方式所得 d′值最高。(3)三种对象关于动觉表象学习所得 d′值 F 检验呈显著性差异证明。动觉表象因学习程度不同存在着水平和层次的差别。(4)动觉表象学习方式所得 d′值与体操成绩呈显著性正相关。d′值可作为衡量体操成绩好差的间接指标。

A Study of the Recognition of Gymnastics Skills in the Light of Signal Detection Theory

This paper discusses some characteristics of recognition about gymnastics movements from the angle of skill forming insports performance and in the light of the Signal Detection Theory.Four different learning methods were adopted,namely,visual image,kinesthesia image,visual image with verbal instructions,and kinesthesia image with verbal instructions.Experi-ments were carried out on subjects of three different kinds,namely,students of education department,students of PE depart-ment in general,and students of PE department majoring in gymnastics.Results of the experiments showed that 1)the valueof d',which denotes the ability to recognize gymnastic movements,improved with the degree of specialization;2)the valueof d'achieved with the kinesthesia learning method was higher than that attained with any other method;3)the remarkabledifferences revealed through F testing of the d'value achieved by the three kinds of subjects showed that there existed differ-ent levels in kinesthesia image because of different levels of learning;4)the d'value achieved in the kinesthesia amage learn-ing method had a high positive correlation with the level of gymnastics performance.
