Summary: | When sighted persons try to identify one of two speech utterances coming from different directions, they display both a
frontal position advantage, i.e., better recognition of inputs from the front than of those from the rear, and a
right-side advantage, better recognition of inputs from the right than of those from the left. The present study demonstrates a dissociation of the two effects in blind subjects (
N = 10) who showed no frontal position advantage together with a right-side advantage superior to that of control sighted subjects (
N = 16). There was no systematic difference between congenitally blind subjects and noncongenitals. The absence of frontal position advantage in the blind is consistent with the notion that this effect originates in the habit of sighted listeners to orient toward the source of heard speech. The occurrence of at least normal right-side advantage in the blind does not support recent suggestions of reduced lateralization of language functions in such subjects. |
