Study Summary

This trial aims to help kids with DLD learn new words by showing an advantage of repeating them over simple exposure.

Who is the study for?
This trial is for four- and five-year-old children with developmental language disorder (DLD), who have a significant deficit in language ability but normal hearing, no neurological damage or disease, nonverbal intelligence scores above intellectual disability range, not on the autism spectrum, and are native English speakers.Check my eligibility
What is being tested?
The study tests retrieval-based word learning during book reading to see if it helps children with DLD remember new words better than just being exposed to them. The goal is to improve their word learning by making them recall these words frequently.See study design
What are the potential side effects?
Since this intervention involves educational techniques rather than medical treatments, traditional side effects are not applicable. However, there may be variations in individual responses to the learning methods used.

Experimental Treatment
Group I: Spaced retrieval practice during word learningExperimental Treatment1 Intervention
Each child will learn 8 novel nouns referring to unfamiliar plants and animals ("nepp") and a related "meaning" ("a nepp likes rain"). Four nouns will be learned in a "spaced retrieval" practice condition; four will be learned in a "study only" practice condition. In the spaced retrieval condition, children will hear the information (word form and meaning) and be asked to immediately retrieve it. Thereafter, they will be asked to retrieve it after hearing 3 intervening word form/meanings. Each retrieval bid will be followed by feedback in the form of hearing the information again. In the "study only" practice condition, children will simply hear the information (word form and meaning).
