The Cerebral Dominance Theory of Stuttering Implies That in PWS

The cerebral dominance theory of stuttering implies that in PWS:

A) the slow peripheral speech musculature cannot make a timely response to an abnormal overflow of neural signals from the left cerebral hemisphere which is usually dominant for speech; the lagging musculature results in stuttering blocks
B) normal cerebral dominance has transferred from the left to the right hemisphere;Neural signals from the right hemisphere, which is not specialized for speech Processing, are slightly disorganized resulting in stuttering blocks
C) cerebral dominance is greatly reduced or lacking. Consequently, neural signals from the two hemispheres reach the bilateral speech musculature in an asynchronous manner resulting in stuttering blocks
D) cerebral dominance alternates randomly between the left and right hemisphere; this Erratic brain function generates conflicting neural signals to the speech musculature Resulting in stuttering blocks
