“…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.…”

This research examined neuropsychological and interpersonal factors that jointly confer vulnerability to youth depression. We proposed that (1) a reduced posterior right hemisphere bias during the processing of facial expressions contributes to subsequent depressive symptoms in youth, and (2) maladaptive responses to interpersonal stress account for this association. Drawing from theory and research indicating sex differences in rates of hemispheric development, we also investigated sex differences in the associations among a reduced posterior right hemisphere bias, maladaptive responses to interpersonal stress, and depressive symptoms. Hypotheses were examined in a longitudinal study of 95 4th – 8th graders (M age = 12.33, SD = 1.10). Results supported the notion that a reduced posterior right hemisphere bias confers vulnerability to depressive symptoms over time in a sex-specific fashion, and implicate maladaptive stress responses as an explanatory mechanism.

“…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.…”

Among right-handers, the magnitude of differences in proficiency between the left and right hands varies considerably. Yet significance of the extent of right-handedness is still a controversial issue. To examine whether individual differences in asymmetry of hand skill can partly be attributed to individual differences in asymmetrical hemispheric activation, handedness and electroencephalographic (EEG) laterality were correlated in two large samples (ns = 60 and 128). Analysis indicated that part of the variability in right-handedness may arise from activation asymmetries in the cortex, but whether this relation becomes apparent depends on the cortical area examined and on the experimental condition under which the EEG measures are taken.

“…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).…”

Accounts of emotion lateralization propose either overall right hemisphere (RH) advantage or differential RH versus left hemisphere (LH) involvement depending on the negative-positive valence of emotions. Perceptual studies generally show RH specialization. Yet viewer emotional responses may enhance valence effects. Because infant faces elicit heightened emotion in viewers, perceptual asymmetries with chimeric infant faces were assessed. First, it was determined that chimeras must be paired with their counterparts, not their mirror images, to tap viewers' sensitivity to adult facial asymmetries. Results showed an RH perceptual bias for infant cries but bihemispheric sensitivity to asymmetries in infant smiles. This effect was not due to LH featural versus RH holistic processing and held for additional, intensity-matched, spontaneous expressions. Specialized RH sensitivity to infant cries may reflect an evolutionary advantage for rapid response to infant distress.
