PS366 Chapter Notes - Chapter 14: Natural Disaster, Microstructure, Coreference
Document Summary
Goal is understanding right hemisphere contributions to language production and comprehension. Including: prosody, words, discourse processing, non-literal language processing. The longitudinal fissure divides the brain in half from front to back, separating the two cerebral hemispheres. A band of nerve fibers called the corpus callossum connects the two hemispheres. Language is generally viewed as strongly left-lateralized: lh damage produces more dramatic symptoms than rh damage, but: imaging and neurological data point to rh contributions to a variety of language functions. *kenny went to the store: question vs. statement. Rh handles linguistic and affective prosody similar to the way the left hemisphere handles semantics and syntax. Prosody is a dominant and lateralized rh function. Prediction: unilateral rhd should impair emotional and linguistic prosody comprehension and production. Evidence for rh prosody hypothesis: rhd in adults leads to impairments in the comprehension and production of emotional prosody, neuroimaging: Rh responds more than lh when emotional prosody is manipulated.
