Electroencephalogram, bilateral ear temperature, and affect changes induced by lateral visual field stimulation.
Fifteen subjects evaluated while wearing, in random order, four pairs of glasses, two limiting vision to either the left or right lateral visual field (LVF) and two monocular glasses (MGs) limiting vision to either eye, manifested significant differences in laterality indices in the predicted direction for the theta electroencephalogram (EEG) (P < .003) and ear canal temperature (P < .02) between the LVF glasses, but not the MGs. There was a significant correlation between lateral shifts in the theta EEG and ear canal temperature (r2 = .47, F(1,10) = 8.72, P < .015). The LVF glasses induced an absolute difference in anxiety greater (P < .05) than that induced by the MGs. LVF glasses appear to induce a shift in affect and hemispheric dominance.
