| Abstract | Attempted to extend V. A. Mann's (see PA, Vol 66:11869) research in 3 experiments with 12 undergraduates, 1 graduate student, and 48 infants (aged 4-6 mo). Ss participated in a signal detection test of discrimination using triads of disyllables. Three equidistant items from a /da/ga/ continuum were used preceded by /al/ and /ar/. In the identification test, adults had identified item
ga5 as "ga," and da1 as "da," following both /al/ and /ar/, whereas they identified the crucial item d/ga3 predominantly as "ga" after /al/ but as "da" after /ar/. In the discrimination test, they discriminated d/ga3 from da1 preceded by /al/ but not /ar/; compatibly, they discriminated d/ga3 readily from ga5 preceded by /ar/ but poorly preceded by /al/. Similar results were obtained with infants. Prelinguistic infants may disentangle consonant-consonant coarticulatory influences in speech in an adult-like fashion. |
