Verbal ability in children

The present study investigated the relation of children’s attentional behaviors to context, gender, and their language skills. Participants were 33 children and their parents. The following attentional behaviors were measured based on coding of video recordings of 30-minute free-play interactions at 30 months: time spent in engaged states (attending to an object, person, or event) and frequency of changes from one engagement state to another. Children’s productive vocabulary and language comprehension were measured using standardized tests at 30, 36, and 42 months. Males spent more time in joint engagement and switched engagement states less frequently. Children spent more time engaged during Animal and Picnic toy play than Book reading. Children attended longer to picnic-related objects than animal-related objects or books, and attended longer to animal- related objects than books. Longer sustained attention—measured as lower frequencies of state switches—was related to higher concurrent and future language comprehension scores.
