先前关于从点光显示器(PLD)识别动作特征的研究集中在与所观察到的动作直接相关的线索上。本文提出了两个实验研究预测无形的运动结果从PLD的可行性。共有127名年龄在19-37岁之间的体育专业学生比较了两次投掷的距离。在实验1中,模型被描述为完整或减少(只有手臂)PLD和对比视频条件。结果表明,条件之间没有差异,但更好的区分性能之间的差异较大的投掷距离。实验2进一步减少了信息。减少PLD到一个点代表的手和减少的时间过程中的手臂球释放点的歧视性能产生不利影响。结果进行了讨论,有关的概念假设使用运动表示运动观察。
Previous research on recognising action features from point-light displays (PLDs) has focused on cues linked directly to the observed action. This paper presents two experiments examining the feasibility of predicting nonvisible movement outcomes from PLDs. A total of 127 sports students aged 19–37 years compared the distances of two throws inbouleswith masked ball flight. In Experiment 1, models were depicted as either full or reduced (only arm) PLDs and contrasted with a video condition. Results showed no differences between conditions, but better discrimination performance for larger differences between throwing distances. Experiment 2 reduced information even further. Both a reduction of PLDs to one point representing the hand and a reduction of the time course of the arm up to the point of ball release had detrimental effects on discrimination performance. Results are discussed in relation to concepts postulating the use of motor representations for movement observation.
