EFFECT OF THE FIELD-DEPENDENT/INDEPENDENT COGNITIVE STYLE ON OPTOKINETIC ILLUSION
场依存性与独立性认知方式对视动错觉的影响

In this research, 100 military university students were tested with Rodand Frame Test, 15 subjects who had high scores and 15 subjects who had lowscores were divided into the field-dependent group and the field-independentgroup respectively, Each subject experienced a series of optokinetic step sti-mulation(5, 10, 15, 20, 30, 40, 60, 80, 100, 120 deg/sec). The latency and fuzzyestimate magnitude of the illusion were recorded. The main results are asfollow. 1. All the latency of the field-dependent group are longer than that ofthe field-independent group, The latency of the field-independent group de-creased linearly with the increase of stimulation velocity, While the field-de-pendent group decreased exponently. 2. Between 5-120 deg/sec, the fuzzy magnitude of the two groups regressedto two linear equations, The coefficient of two equations have no significantdifference, but the intercepts have significant difference. Consequently, the field-dependent/independent cognitive style is an im-portant factor that has influence on producing optokinetic illusion, It is veryhelpful for psychological selection and training of military pilots.
