Effects of prosodic stress and serial position on syllable omission in first words

Abstract

The authors documented syllable omission in one child's multisyllabic vocabulary from 10 to 20 months of age to evaluate L. Gerken's (1991, 1994a, 1994b) proposal that children organize their productions according to a trochaic metrical (strong-weak) template and omit syllables from target utterances that do not conform to this pattern. The trochaic template hypothesis was not supported by these early productions. Results indicated that the likelihood of producing a target syllable was influenced primarily by the strength of the prosodic stress placed on it and secondarily by its serial order within a word. Over time, the child demonstrated an increasing ability to include syllables with weaker prosodic stress in multisyllabic productions. Omissions became much less common with the onset of 2-word speech.
