The use of differing verb types in the oral narratives of school-age children.

The aim of this project was to examine age-related use of action, metacognitive, and metalinguistic verbs because factors related to verb transparency are thought to impact word learning. Performance on fictional, oral narratives elicited using a single-episode picture was evaluated for 84 children with typical language (TL) and 38 age-matched children with a Developmental Language Disorder (DLD) ranging in age from 5;1 to 14;4 years of age. Narrative samples were transcribed and coded for occurrences of action verbs (AV), metacognitive verbs (MCV), and metalinguistic verbs (MLV). The total number of verbs used and the number of different verbs produced in each category were examined across ages, as was the difference in verb usage patterns across language ability groups. A statistically significant increase in the overall use of action, MCV, and MLV with age was observed. TL children used a wider variety of each verb type as compared to those with DLD. Age-related progression for verb use was observed in the fictional narrative generation task by both groups of children. However, despite similar rates of total verb use, children with DLD produced fewer different verbs in the three categories. These findings indicate the total number of verbs used is similar in children with TL and DLD, but there is a difference in the number of different verbs used in functional tasks such as narratives for children with DLD. These results also indicate a need for ongoing examination of the factors not only impacting verb acquisition but also use in communication tasks.
