Electroencephalographic Correlates of Perceptual Style: Field Orientation

Abstract
Eeg responses for 74 subjects were found to correlate with their field orientation as measured by the rod-and-frame test. There was a differential reactivity to visual and auditory stimuli in relation to field orientation, but with responses occurring in opposite directions with the 2 different kinds of stimuli. During a period of recording with eyes open, it was found that field-independent subjects sustained significantly more alpha activity than did their field-dependent counterparts. The concept of field orientation appears to be a potentially useful framework within which relationships between psychological and neurophysiological organization may be studied.
