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 degrees/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 degrees/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.
