SMU Lecturer of Psychology Dr Andree Hartanto and SMU PhD in Psychology student Wei Xing Toh wrote that video gaming has been a source of serious concern for parents and educators, based on the belief that video games disrupt adolescents' academic activities. However, previous studies have been mixed regarding video games’ effects on academic outcomes. The writers’ research revisited this issue by analysing data on approximately 30,000 adolescents from three large-scale public datasets. They consistently found that the more adolescents played video games on weekdays, the poorer they performed on standardized assessments of mathematics, reading, and science. In contrast, weekend video gaming was positively associated with academic performance. Their findings suggest that weekday and weekend video gaming may be differentially associated with academic outcomes, depending on the context in which it occurs.
