The Influence of Language Set on Ear Preference in Phoneme Recognition

Abstract
Language expectation (L) and non-language expectation (NL) groups were tested for recognition of dichotically presented CVC nonsense syllables differing in medial vowel or initial stop consonant. Each group comprised 58 right handed Ss with no history of hearing defect. Both L and NL groups showed superior recognition for consonant varied syllables presented to the right ear. Group L showed right ear superiority in recognition of vowel varied syllables while group NL showed left ear superiority for the same syllables. The reversal of ear superiority in the recognition of vowel varied syllables is interpreted as being due to increment or decrement of right ear performance rather than to bilateral functional asymmetry of the brain.
