Abstract

Aim 1 of this study was to examine the developmental changes in typically developing English-speaking children’s syntactically-based sentence interpretation abilities and sensitivity to word order. Aim 2 was to determine the psychometric standing of the novel sentence interpretation task developed for this study, as we wish to use it later with children with Specific Language Impairment (SLI). Children listened to semantically implausible sentences in which noun animacy and the natural affordance between the nouns were removed, thus controlling for event probability. Using this novel “whatdunit?” agent selection task, 256 children 7-11 years listened to two structures with canonical word order and two with non-canonical word order. After each sentence, children selected as quickly as possible the picture of the noun they believed was “doing the action.” Children interpreted sentences with canonical word order with greater accuracy and speed than those with non-canonical word order. Older children (AgeM = 10:8) were more accurate and faster than younger children (AgeM = 8:1) across all sentence forms. Both older and younger children demonstrated similar error patterns across sentence type. The “whatdunit?” task also proved to have strong validity and reliability, making it suitable for studies with children with SLI.
