GoKawiilSingapore study links early childhood screen time to lower academic scores at age 9
A birth-cohort study tracking 502 Singaporean children from age 1 to 8 found that higher screen viewing time, especially at age 1, 1.5 and 6 years, was linked to weaker academic performance at age 9 and poorer working memory at 10.5, even after adjusting for other factors. Cumulative screen exposure across childhood also predicted lower academic performance, though not working memory.
