Electroencephalogram, bilateral ear temperature, and affect changes induced by lateral visual field stimulation

Fifteen subjects evaluated while wearing, in random order, four pairs of gl asses, two limiting vision to either the left or right lateral visual field (LVF) and two monocular glasses (MGs) limiting vision to either eye, manif ested significant differences in laterality indices in the predicted direct ion for the theta electroencephalogram (EEG) (P < .003) and ear canal tempe rature (P < .02) between the LVF glasses, but not the MGs. There was a sign ificant correlation between lateral shifts in the theta EEG and ear canal t emperature (r(2) = .47, F(1,10) = 8.72, P < .015). The LVF glasses induced an absolute difference in anxiety greater (P < .05) than that induced by th e MGs. LVF glasses appear to induce a shift in affect and hemispheric domin ance.
