Visual-spatial-frequency model of cerebral asymmetry: a critical survey of behavioral and electrophysiological studies.
In this article, the authors present a review of research on the role of the 2 hemispheres in processing spatial frequencies. J. Sergent (1982a) postulated that the hemispheres differ in their sensitivity to frequency characteristics of the sensory outputs on which cognitive processes are performed. Specifically, she proposed that the right hemisphere displays greater efficiency than the left hemisphere in processing low-spatial-frequency content of a visual image, whereas the left hemisphere is better equipped than the right to deal with high frequencies. The authors present an extensive review of behavioral and electrophysiological studies whose researchers tried to verify Sergent's hypothesis and offer its reformulation, taking into account the findings that have accumulated in the last 10 years.
