Yes. Multiple recent longitudinal and empirical studies support the association between excessive screen time (including television viewing) and lower cognitive test performance, executive dysfunction, and reduced academic achievement in youth.

The analysis

A robust body of recent longitudinal and survey-based research consistently indicates that excessive screen time and television viewing are associated with lower cognitive performance, poorer executive function, and reduced academic outcomes among children and adolescents. The retrieved papers consistently support this relationship without contradictory findings regarding overall cognitive performance, leading to a verdict of SUPPORTED.
