| Abstract: | The results of a series of four dichotic listening experiments confirm that under appropriate conditions vowels show a right ear advantage (REA) comparable to that of consonants. The conditions all cause perceptual difficulty, adversely affecting the accurate registration of both inputs in the auditory system. The addition of noise, shortening of the vowel stimuli, and the use of a more confusable set of vowels, each had the effect of increasing REA. Results are compatible with an explanation of ear advantage in terms of competition at the auditory rather than the phonetic level, in which short-term precategorical acoustic storage (PAS) may play a critical role. |
