ABSTRACT

Digital screen exposure has become an integral part of children's daily lives due to the widespread use of smartphones, tablets, computers, and televisions. While digital technologies offer educational and social benefits, increasing evidence suggests that excessive or inappropriate screen exposure during early childhood may adversely affect neurodevelopment. This literature review synthesizes current research on the relationship between digital screen exposure and neurodevelopmental outcomes, including cognitive development, language acquisition, attention, executive functioning, sleep, emotional regulation, and social behavior. Studies indicate that prolonged screen time, particularly passive media consumption and exposure before the age of two years, is associated with delayed language development, reduced attention span, impaired executive functioning, and poorer sleep quality, all of which may influence brain maturation. Conversely, high-quality educational content, parental co-viewing, and age-appropriate screen use can support learning and cognitive development when used in moderation. Factors such as screen content, duration, timing, and family environment significantly influence developmental outcomes. Despite growing evidence, inconsistencies remain due to variations in study design, measurement methods, and confounding variables. Overall, the literature highlights the need for balanced digital media use, adherence to pediatric screen-time guidelines, and increased parental awareness to minimize potential risks while maximizing the benefits of digital technology. Further longitudinal and experimental research is required to establish causal relationships and inform evidence-based recommendations for healthy digital media use during critical periods of neurodevelopment.
