Brain Basis
Neural data provide correlates of CP and of learning. Differences between event-related potentials recorded from the brain have been found to be correlated with differences in the perceived category of the stimulus viewed by the subject. Neural imaging studies have shown that these effects are localized and even lateralized to certain brain regions in subjects who have successfully learned the category, and are absent in subjects who have not.
Categorical perception is identified with the left prefrontal cortex with this showing such perception for speech units while this is not by posterior areas earlier in their processing such as areas in the left superior temporal gyrus.

Famous quotes containing the words brain and/or basis:
“Let every woman ask herself: “Why am I the slave of man? Why is my brain said not to be the equal of his brain? Why is my work not paid equally with his? Why must my body be controlled by my husband? Why may he take my labor in the household, giving me in exchange what he deems fit? Why may he take my children from me? Will them away while yet unborn?” Let every woman ask.”
—Voltairine Decleyre (1866–1912)
“Most young black females learn to be suspicious and critical of feminist thinking long before they have any clear understanding of its theory and politics.... Without rigorously engaging feminist thought, they insist that racial separatism works best. This attitude is dangerous. It not only erases the reality of common female experience as a basis for academic study; it also constructs a framework in which differences cannot be examined comparatively.”
—bell hooks (b. c. 1955)
