Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Children with developmental language disorder (DLD; also referred to as specific language impairment) experience a significant deficit in language ability that is longstanding and harmful to the children's academic, social, and eventual economic wellbeing. Word learning is one of the principal weaknesses in these children. This project focuses on the word learning abilities of four- and five-year-old children with DLD. The goal of the project is to determine whether special benefits accrue when these children must frequently recall newly introduced words during the course of learning. In the current study, the investigators compare a "standard" repeated spaced retrieval schedule, with fixed spacing between hearing a word and attempting to retrieve it, to an "adaptive" repeated spaced retrieval schedule in which opportunities to retrieve a given word are tailored to the individual child's current knowledge state. The goal of the study is to determine whether the adaptive schedule can increase children's absolute levels of learning while maintaining the advantages of repeated spaced retrieval.
