Binaural processing of dichotic CV's in a split brain child

Performance of musicians and nonmusicians on dichotic chords, dichotic CVs, and dichotic digits.

Perception of dichotic chords (free recall and directed recall), nonsense syllables (CVs), and three-pair digits was assessed on 24 musicians and 24 nonmusicians. On the dichotic-CV and dichotic-digit free-recall tasks, there was a significant right-ear advantage, but there were no group differences. With the dichotic-chords, free-recall condition, a significant left-ear advantage was observed ...

Dichotic testing of partial and complete split brain subjects.

Four subjects with differing portions of the cerebral commissures sectioned were tested in a consonant vowel dichoticlistening task. The two subjects withsections anterior to the splenium and posterior to the first one third of the corpus callosum failed to identify any of the syllables presented to the left ear under dichotic presentation, even under conditions designed to optimize processing ...

Inferences from Dichotic Pitch for Binaural Modeling

A dichotic pitch can be perceived due to the binaural presentation of white noise with a particular interaural phase relationship. Three perceptual aspects are characteristic: the pitch value, the timbre of the phenomenon, and the lateralized position of the pitch image. As dichotic pitch phenomena are generally considered to be natural epiphenomena of the mechanisms of binaural hearing, infere...

The effect of dichotic processing on the perception of binaural cues

Hearing impaired individuals often have difficulty hearing in noise because of reduced spectral resolution. Previous research suggests that dichotic processing, where information from neighboring frequency regions is sent to opposite ears, may benefit those individuals. However, dichotic processing can degrade binaural cues, reducing spatial release from masking and localization accuracy. In th...
