Multisyllabic nonwords: More than a string of syllables

Abstract

Nonword repetition is closely associated with the learning of the phonological form of novel words. Several factors influence nonword repetition performance such as short-term memory, phonotactic probability, lexical knowledge, and prosodic factors. The present study examined the influence of list duration, coarticulation, and prosody on nonword repetition by comparing naturally articulated multisyllabic nonwords to multisyllabic nonwords formed by concatenating syllables produced in isolation and serial lists (experiment 1), to multisyllabic forms that incorporated either valid or invalid coarticulatory information (experiment 2), and to multisyllabic forms either with or without common English within-word stress patterns (experiment 3). Results revealed superior recall for naturally articulated nonwords compared to lists of matched duration or sequences with invalid coarticulatory cues. Within-word stress patterns also conveyed a repetition advantage. The findings clearly establish that the coarticulatory and prosodic cues of naturally articulated multisyllabic forms support retention.
