听觉似动条件下对位置距离估计的加工机制

Processing Mechanism of Position Distance Estimation Under the Condition of Auditory Apparent Motion

作为盲人的重要感官之一,听觉在其生活中发挥了重要的作用。采用听觉通道下的空间距离估计实验,研究在听觉似动条件下盲生与视力正常学生对空间距离的估计是否存在差异以及相应的影响因素。结果发现,在听觉似动条件下,视力正常学生与盲生对位置距离的估计差异边缘显著,视力正常学生估计的距离更接近真实值;视力正常学生与盲生对位置距离的估计都受刺激时间间隔的影响,刺激时间间隔起调节作用;声音频率对位置距离估计的影响差异不显著。研究支持缺陷说理论。

As one of the important senses of blind people, hearing plays an important role in their life. Using the spatial distance estimation experiment under the auditory channel, this paper studies whether there is difference in the estimation of spatial distance between blind students and sighted students under the condition of auditory apparent movement and the corresponding influencing factors. The results show that: under the condition of auditory apparent motion, the distance estimated by the sighted students and the blind students was significantly different, and the distance estimated by the sighted students was closer to the real value.The estimation of position distance between blind and sighted students is affected by the time interval of stimulation.The time interval of stimulus plays a regulatory role. The influence of sound frequency on position distance estimation is not significant. The study supports the defect theory.
