Effect of Phonotactic Probability and Neighborhood Density on Word-Learning Configuration by Preschoolers With Typical Development and Specific Language Impairment

Effect of phonotactic probability and neighborhood density on word-learning configuration by preschoolers with typical development and specific language impairment.

PURPOSE In this study, the authors assessed the effects of phonotactic probability and neighborhood density on word-learning configuration by preschoolers with specific language impairment (SLI) and typical language development (TD). METHOD One hundred thirty-one children participated: 48 with SLI, 44 with TD matched on age and gender, and 39 with TD matched on vocabulary and gender. Referent...

Triggering word learning in children with Language Impairment: the effect of phonotactic probability and neighbourhood density*

The effect of phonotactic probability (PP) and neighbourhood density (ND) on triggering word learning was examined in children with Language Impairment (3;04-6;09) and compared to Typically Developing children. Nonwords, varying PP and ND orthogonally, were presented in a story context and their learning tested using a referent identification task. Group comparisons with receptive vocabulary as...

Differentiating phonotactic probability and neighborhood density in adult word learning.

PURPOSE The purpose of this study was to differentiate effects of phonotactic probability, the likelihood of occurrence of a sound sequence, and neighborhood density, the number of words that sound similar to a given word, on adult word learning. A second purpose was to determine what aspect of word learning (viz., triggering learning, formation of an initial representation, or integration with...

Word learning by children with phonological delays: differentiating effects of phonotactic probability and neighborhood density.

UNLABELLED This study examined the ability of 20 preschool children with functional phonological delays and 34 age- and vocabulary-matched typical children to learn words differing in phonotactic probability (i.e., the likelihood of occurrence of a sound sequence) and neighborhood density (i.e., the number of words that differ from a target by one phoneme). Children were exposed to nonwords pai...
