This dataset includes data analysed in a meta-analysis on word learning abilities in children with Developmental Language Disorder (DLD). It contains all data extracted from each of the 46 studies that met inclusion criteria, each comparing word learning in children with DLD to their typically developing peers.
The studies used a variety of experimental tasks, therefore the dataset includes detailed information on task characteristics, such as the number of words taught, maximum word length, exposure frequency, type of instruction (explicit or implicit), and outcome measures. Additionally, it specifies the stage of word learning assessed in each study (encoding, consolidation, or retention).
Demographic details about participant groups are included, along with data on children’s cognitive and linguistic profiles as reported in each paper. This dataset is a valuable resource for exploring the types of experimental word learning tasks in the literature, examining task characteristics and participant profiles, and investigating word learning outcomes for children with DLD compared to typically developing children.
