Effects of Field-dependent Cognitive Style on Optokinetic Illusion
Abstract：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.
