Hemispheric processing of spatial frequencies in two commissurotomy patients.
To test the hypothesis that in humans the left brain hemisphere is specialized for processing high spatial frequencies while the right hemisphere is specialized for processing low spatial frequencies, pairs of Gaussian windowed sinusoidal gratings were presented for 167 msec within the left and right visual fields of two commissurotomy patients. The gratings employed had spatial frequencies ran...
متن کاملA Developmental Model of Hemispheric Asymmetries of Spatial Frequencies
Lateralization touches virtually every function we think makes us human and interacts fundamentally with development. Here we connect lateralized function to anatomical asymmetries, and connect those anatomical asymmetries to temporal asymmetries in development. Our differential encoding (DE) model (Cipollini, Hsiao, & Cottrell, 2012; Hsiao, Cipollini, & Cottrell, 2013; Hsiao, Shahbazi, & Cottr...
متن کاملPersistent Hemispheric Differences in the Perceptual Selection of Spatial Frequencies
Previous research has shown that the right hemisphere processes low spatial frequencies more efficiently than the left hemisphere, which preferentially processes high spatial frequencies. These studies have typically measured RTs to single, briefly flashed gratings and/or have directed observers to attend to a particular spatial frequency immediately before making a judgment about a subsequentl...
متن کاملReading laterally: the cerebral hemispheric use of spatial frequencies in visual word recognition.
It is generally accepted that the left hemisphere (LH) is more capable for reading than the right hemisphere (RH). Left hemifield presentations (initially processed by the RH) lead to a globally higher error rate, slower word identification, and a significantly stronger word length effect (i.e., slower reaction times for longer words). Because the visuo-perceptual mechanisms of the brain for wo...
متن کاملVisual space-time interactions: effects of adapting to spatial frequencies on temporal sensitivity.
To study how adaptation to spatial frequency patterns affects temporal sensitivity in vision, observers were selectively adapted for 4 min to either a high- or a low-spatial-frequency sinusoidal grating (12 and 2 cpd, respectively). Their sensitivities to modulation of a blurred patch at high or low temporal frequencies (12 Hz and 2 Hz, respectively) were measured, before and after the adaptati...
