Abstract
Primary auditory stream segregation—the perceptual segregation of acoustically related elements of a continuous auditory sequence into spatially distinct streams—disrupts recovery of the relative temporal order of repeated sequences of consonant and vowel syllables. Three experiments were performed to determine why the apparent temporal order of natural speech is not similarly disrupted. Exp. 1 (N = 24) showed that the disruption is not dependent on repetition of the 32 experimental sequences of consonant and vowel syllables. Exps. 2 (N = 48) and 3 (N = 20) showed that when 4 English monosyllables are used as stimuli and syntactic and intonational structure is present then the temporal integrity of the acoustic signal is preserved perceptually. Despite accurate resolution of order for the 40 experimental sequences, errors of words were common. These errors often imposed a syntactic organization on the resulting sequence.
