Hemispheric potentials evoked by speech sounds during discrimination tasks

Abstract

We studied the feasibility of adapting the method of Wood et al. (1971) for determining cerebral dominance for language and did not obtain consistent asymmetries of evoked responses in the left hemisphere to stop consonant task (SCT) as compared with fundamental frequency task (FFT). Likewise, the right hemisphere-evoked potentials for SCT and FFT did not show consistent asymmetries. However, we did find that the evoked responses at T3 were attenuated as compared with those at T4, regardless of the task performed (FFT or SCT). These findings may be useful in developing a test for cerebral dominance for language.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
