A Systematic Literature Review on Sleep and Language Learning: Surveying Existing Literature from a Biopsychosocial Perspective

This review examines trends and patterns in research investigating relationships between sleep and language learning from a biopsychosocial perspective. Sleep deprivation, being prevalent among adolescents, impacts academic performance, cognitive development, and language skills. We have conducted this review using the method of a systematic literature review in order to understand any types of gaps that exist amongst current literature. While existing research focuses on toddlers, children, and adults, a significant gap exists in understanding its effects on adolescents. We screened an initial 242 articles, however there were only 43 left that were selected to meet the criteria, and we then categorized them by age, population characteristics, and levels of analysis. Findings show a disproportionate focus on younger age groups and individual-level analyses, with cultural contexts often neglected. Our review emphasizes the need for more adolescent-focused research and the inclusion of cultural analyses to better understand and address the diverse needs of students and learners.
