摘　　要：目的探讨场依存性认知方式对视动性错觉的影响。方法本研究对 1 0 0名男性军校学员进行了棒框测验 ,1 5名高分者和 1 5名低分者分别作为场依存组和场独立组。每名被试 ,随机给予一系列视动阶跃刺激 ( 5 ,1 0 ,1 5 ,2 0 ,30 ,40 ,60 ,80 ,1 0 0 ,1 2 0°/s)每个刺激持续 2 0s。记录被试报告的视动错觉出现的潜伏期和错觉模糊量。结果 1 )场依存组被试的错觉潜伏期短于场独立组 ,它与刺激速度呈幂函数关系 ,而场独立组潜伏期随刺激速度的增加呈直线下降 ;2 )在 5～ 1 2 0°/s,两组被试错觉量回归成两条直线 ,两直线回归系数无显著差异 ,而截距差别十分显著。结论场依存性认知方式是视动错觉个体差异性的一种重要影响因素 ,场依存者易于发生视动性错觉。Objective To study the effects of the field-dependent cognitive style on optokinetic illusion. Method One hundred military university students were tested with Rod and Frame Test.Fifteen high score subjects and 15 low score subjects were arranged into field-dependent group and field-independent group respectively. Each subject experienced a series of optokinetic step stimulation (5, 10, 15, 20, 30, 40, 60, 80, 100, 120°/s )for 20 s. The latent period and fuzzy estimate magnitude of the illusion were recorded. Result The results obtained were as follows:1) The latent period in the field-dependent group were shorter than that in the field-independent group, and decreased exponentially with the stimulation. The latent period in the field-independent group decreased linearly with stimulus;2) Between 5～120°/s, the fuzzy magnitude of the two groups regressed to two linear equations, no significant difference was found between the coefficients of two equations, but the intercepts were significantly different. Conclusion Cognitive style was found to be an important influencing factor on optokinetic illusion. People with the field-dependent cognitive style were susceptible to optokinetic illusion.
