Dichotic listening 2

Alan Cruttendon writes, in his book-length treatment of the prosody in language, Intonation, published 1997 by Cambridge University Press, the following:

"While the links between intonation and punctuation apply, of course, only to literate societies, the links between intonation and gesture are of an altogether more primitive sort. That intonation is a unique part of language is clearly demonstrated from experiments in dichotic listening. In this sort of experimentation similar auditory material is fed to the two ears and the listener shows a preference for the material presented to one ear. For language generally, for tone in tone languages, and even for consonant-vowel nonsense syllables, an advantage is shown for the right ear, which involves the left hemisphere of the brain; whereas a left ear (right hemisphere) advantage is shown for intonation, along with music and general environmental noises. So it is not surprising that in a large majority of cases of acquired language disorders, and even in cases of severe phonological or grammatical disorder, intonation is unaffected. In those few cases in which intonation is affected, patients may well have gestural problems as well. This suggests a close connection between intonation and gesture." [177]

Dichotic listening?

What about the listening of sound refracted through the hundred tiny lenses of the eye of the fly? What becomes of listening passed through the compound eye that, per force, must reassemble its contents in the form of a mosaic? Through the pincers of a dichotomy we come only to the doorstep of gesture, and of shape.
