Developmental Changes in Narrative and Non-Narrative Discourse in Children with and without Brain Injury.

This study presents a set of narrative and non-narrative tasks and analytic procedures for examining the discourse development of children with perinatal brain injury and typically developing children. Three oral discourse genres were collected at ages 5, 6, and 7: script, picture description, and replica play narration. Genre performances were assessed for the presence of hypothesized genre features. Results suggest these tasks and procedures are able to characterize development in discourse abilities for both a normative group and for children with perinatal brain injury. The group of children with brain injury produced shorter discourse performance with more off-task talk. This group also showed difficulty in fully differentiating the various genre types and in creating integrated discourse performances. However, most of these children demonstrated considerable growth in control of genre features over this time period. The possible utility of these tasks and procedures for clinical assessment is discussed.

Just pretend: Participation in symbolic talk by children with histories of early corrective heart surgery

Children with histories of early corrective heart surgery (ECHS) are at risk for language, cognitive, and motor delays. This study examined parent–child play in 30 4-year-old children with ECHS and 30 typically developing children. Children were compared on basic language measures and on proportions of symbolic and nonsymbolic talk. Children with ECHS focused on concrete “here-and-now” talk and produced less symbolic talk than normative children. Only a third of the children with ECHS were able to produce story episodes. These findings reflect the ECHS childrens relatively immature participation in joint pretense and their overreliance on earlier acquired strategies for pretend play. This style of participation may result from difficulty coordinating more complex social intentions with appropriate language forms.
