“…First, the posterior right hemisphere is activated during face processing, as indicated by findings from tachistoscopic tasks (e.g., Hilliard, 1973; Klein, Moscovitch, & Vigna, 1976), lesion studies (e.g., Newcombe, De Haan, Ross, & Young, 1989), and neuroimaging studies (e.g., Sams, Hietanen, Hari, Ilmoniemi, & Lounasmaa, 1997; Sergent, Ohta, & MacDonald, 1992). Second, electrophysiological activation in posterior regions of the brain explains 50% of the variance in behaviorally assessed perceptual asymmetry scores (Green, Morris, Epstein, West, & Engler, 1992), which suggests that such tasks index patterns of regional brain activity. Research also supports the idea that performance on the CFT reflects individual differences in the processing of emotional information.…”

“…The latter assumption implies that activation asymmetries affect the relative efficiency of the hemispheres. Evidence for this has been provided by studies which showed that individual differences in the magnitude of visual half-field advantages or ear advantages in a dichotic listening task can partly be attributed to cortical activation asymmetries measured by electroencephalogram (EEG) (Green, Morris, Epstein, West, & Engler, 1992;Davidson & Hugdahl, 1996). Most importantly, activation asymmetries were assessed at rest in these studies, thus supporting the hypothesis of Levy, et al (1983) that characteristic temporally stable patterns of asymmetrical activation may influence the cognitive asymmetries that can be observed with behavioural tests.…”

“…Indeed, subjects' free-field perceptual biases are predicted by their asymmetries on tachistoscopic tasks (Burton & Levy, 1991;Kim, Levine & Kertesz, 1990;Hellige, Bloch & Taylor, 1988;Wirsen et al, 1990). The correlation reflects individual variations in characteristic arousal differences between the hemispheres (e.g., Levy, Heller, Banich & Burton, 1983b), which are corroborated by individual differences in EEG alpha asymmetry in the parietal and temporal regions (Green, Morris, Epstein, West & Engler, 1992), which include the cortical projection area of the posterior, visuo-spatial attention system (Posner & Peterson, 1990).…”
