The power of imageability: How the acquisition of inflected forms is facilitated in highly imageable verbs and nouns in Czech children
Abstract
Imageability is the ability of words to elicit mental sensory images of their referents. Recent research has suggested that imageability facilitates the processing and acquisition of inflected word forms.
The present study examined whether inflected word forms are acquired earlier in highly imageable words in Czech children. Parents of 317 children (mean age 28 months) were asked whether their child used specific forms of 63 nouns and 35 verbs.
For nouns, the forms were nominative singular and plural; for verbs, third person singular present, second person singular present, and the past participle. Plural nouns, and second person and past participle verbs were considered the marked, inflected forms.
Analyses revealed that imageability is positively related to the use of the inflected form, even when controlling for the use of the unmarked form in each child, and the inflected form frequency. Two main explanations are suggested: facilitation of form retrieval from long-term memory, or facilitation of inflected form processing, especially by supporting the representations in working memory.
