Ear advantages for temporal resolution in baboons.
On the assumption that temporal resolution underlies an individual's ear advantage for speech perception, one would predict an ear advantage for a temporal resolution task to correlate precisely with an ear advantage for the discrimination of consonant-vowel syllables that differ in their temporal features. A gap detection task that required the resolution of brief silent intervals in bursts of noise was employed to test this hypothesis in four baboons. The findings offer support for such a hypothesis and thus increase the feasibility of an animal model of functional asymmetry in the auditory system.
