A. Grabowska et A. Nowicka, VISUAL-SPATIAL-FREQUENCY MODEL OF CEREBRAL ASYMMETRY - A CRITICAL SURVEY OF BEHAVIORAL AND ELECTROPHYSIOLOGICAL STUDIES, Psychological bulletin, 120(3), 1996, pp. 434-449
In this article, the authors present a review of research on the role
of the 2 hemispheres in processing spatial frequencies. J. Sergent (19
82a) postulated that the hemispheres differ in their sensitivity to fr
equency characteristics of the sensory outputs on which cognitive proc
esses are performed. Specifically, she proposed that the right hemisph
ere displays greater efficiency than the left hemisphere in processing
low-spatial-frequency content of a visual image, whereas the left hem
isphere is better equipped than the right to deal with high frequencie
s. The authors present an extensive review of behavioral and electroph
ysiological studies whose researchers tried to verify Sergent's hypoth
esis and offer its reformulation, taking into account the findings tha
t have accumulated in the last 10 years.
