A total of 898 junior high school students in grades 7 to 9 from Ganzhou City, Jiangxi Province, China, were selected for this study with the necessary approvals from both schools and parents. The study was conducted as a group survey with the supervision of a psychology professional, and was administered during class time.
This dataset incudes data from 248 second graders (7- to 8-year-olds) with typical development from three states. One hundred sixty-seven were monolingual English-speaking and 81 were dual Spanish- and English-speaking. Participants completed a comprehensive battery of working memory assessments and six word learning tasks that assessed the creation, storage, retrieval, and production of phonological and semantic representations of novel nouns and verbs and the ability to link those representations.
