遮挡范式下速度对碰撞位置估计的影响
The Influence of Speed on Location-To-Collision Estimation in the Occlusion Paradigm
摘要: 以往关于速度知觉的研究都以被试对碰撞时间的估计为速度知觉的操作性定义，本研究采用遮挡范式，以被试对碰撞位置的估计为速度知觉的操作性定义，通过不同速度的设计，比较不同运动速度对速度知觉实验碰撞位置估计的影响。被试为30名在校大学生，使用速度知觉仪获取和记录数据。研究结果表明运动速度对碰撞位置的估计影响显著，速度快时，估计碰撞位置与出发点的距离比实际碰撞位置与出发点的距离长；速度慢时，估计碰撞位置与出发点的距离比实际碰撞位置与出发点的距离短。最后讨论研究结果的应用意义。
Abstract: The estimation of Time-To-Collision was used to represent speed perception in previous studies. In this research, however, the estimation of Location-To-Collision is used to stand for speed perception and the occlusion paradigm was applied to investigate the influence of different speed on the estimation of Location-To-Collision. Participants were 30 college students from South China Normal University; data were reported by the speed perception instrument. The result indicates that the influence of speed on Location-To-Collision estimation in the occlusion paradigm is significant; the estimation of Location-To-Collision goes beyond where the spot supposed to be in high speed condition and goes within where the spot supposed to be in low speed condition. At the end of this paper, the application of the estimation of Location-To-Collision is discussed.
