摘要/Abstract

摘要： ３０名男性军校学员。在两种指导语指导下，经受了一系列视动跃跃刺激（５、１０、１５、２０、３０、４０、６０、８０、１００、１２０度／秒），每个刺激持续２０秒。用磁带机记录被试的视动性眼震信号，同时，记录被试视动性错觉出现的潜伏期和错觉量。视动性眼震信号在７Ｔ１７信息处理仪上进行脱机采样处理，错觉量用模糊集途径进行量化。主要结论如下：１．视动性眼震的快相速度、慢性速度、快相幅度、慢性幅度均随刺激速度增加而增大，在６０－１２０度／秒范围达到峰值后，基本维持稳定状态，而快慢相时间却有相反的变化趋势，其随刺激速度增加而减小，在６０度／秒达到最低值，然后略有回升。２．在５－１２０度／秒内，视动性错觉随刺激速度的增加而增大，呈直线上升。３．视动性眼震与视动性错觉不存在因果关系。低速度视动刺激下，当视动性眼震被抑制时，错觉量明显增大，说明视动性眼震减轻了视动性错觉。

Abstract: In this research 30 military university students each experienced a series of optokinetic step stimulation(5 , 10,15,20,30,40,60,80,100,120deg/sec)under two different instructions, Each stimulus continued for 20 seconds. The optokinetic nystagmus was recorded with tape recorder, at the same time, the latency and fuzzy estimate magnitude of the illusion were recorded. The nystagmus was analysed with a computer analysis system of ENG,the magnitude of illusion was measured with a fuzzy set model to estimate the magnitude of vestibular sensation.The main results are as follows:1.The SV, FV, SA, FA of Optokinetic nystagmus incresed with optokinetic speed, between 60-120/s, after that they stayed constant,but the ST and FT were different by decresing with stimulus speed, the lowest point was at 60/s, then incresing slowly.2. Between 5-120/s,the magnitude of optokinetic illuision incresed with stimulus speed lineally.3.There was no cause and result between OKN and optokinetic illusion. OKN does not elict optokinetic illusion, and optokinetic illusion does not produce OKN.Under low stimulus velocity,the fuzzy magnitude of the illusion increased significantly while the OKN was refrained. Indicating that OKN reduced the optokinetic illusion.

Key words: optokinetic stimulus, optokinetic nystagmus, optokinetic illusion
