On The Field Dependent, Field Independent-type Individual Information Processing Brain Mechanism

Cognitive styles refer to the individual differences brought out in the course of organizing and processing information, which is regarded as the bridge between the two major traditional research fields in psychology——cognition and individuality. People tend to show differences in the course of their cognition, while this individual difference is constant. ERPs is the totality of potentials in posterior synapses and reflects the signals of electroencephalographic activities simultaneous with stimulation. The ERPs technology is a valuable means to further investigate the cerebral mechanism of individuals with different cognitive styles in the course of information processing. By using such means and technology as behavioral performance, ERPs and ERP topography, this research discusses the electroencephalographic activities during the course of various tasks by individuals with different cognitive styles, including the unanimous judgment of graphics, face cognition, Chinese vocabulary processing and so on. The discussion on this issue helps to make clear, both in time and in space, the cerebral mechanism of individuals with different cognitive styles in the course of information processing, further our understanding of the individual differences and have a better command of the individual differences between people in the course of information processing.What the research results showed are as follows: (1)In a task on the unanimous judgment of graphics involving wholistic-analytic strategy, the difference of peak-to-peak between N85 and P160 in the frontal pole and the central area of the field-dependent individuals is more than that of the field-independent; and the amplitude of the N120 in the occipital...
