“…For the effect of screen time on the change in intelligence, no type of screen time differed between gender. This is in contrast with a longitudinal study where only in men there was an effect of television and video game time at 11 years old on the working memory and the intelligence of those same participants later at 18 years old 12 .…”

“…The results showed that watching TV (as well as, independently, playing video games, and using/watching on computers) had positive effects on later measures of working memory and intelligence 12 . These effects were already accounting for many potential confounders, such as gender, ethnicity, birth weight, household income, and maternal education 12 . The reader might be left wondering: What could be behind the benefits from passively watching digital content?…”

Digital media defines modern childhood, but its cognitive effects are unclear and hotly debated. We estimated the impact of different types of screen time (watching, socializing, or gaming) on children’s intelligence while controlling for genetic differences in cognition and socioeconomic background. We analyzed 9855 children from the ABCD dataset with measures of intelligence at baseline (ages 9-10) and after two years. At baseline, time watching and socializing were negatively correlated with intelligence, while gaming had no correlation. After two years, gaming positively impacted intelligence, but socializing had no effect. This is consistent with cognitive benefits documented in experimental studies on video gaming. Unexpectedly, watching videos also benefited intelligence, contrary to prior research on the effect of watching TV. Broadly, our results are in line with research on the malleability of cognitive abilities from environmental factors, such as cognitive training and the Flynn effect.

“…The authors followed up 3800 children from birth and collected cognitive and screen time data (TV, video game, and computer) at ages 11, 15, and 18. The results showed that watching TV (as well as, independently, playing video games, and using/watching on computers) had positive effects on later measures of working memory and intelligence 12 .

“…Perhaps the only solid evidence that supports cognitive benefits from watching digital media is from a recent study in Brazil 12 . The authors followed up 3800 children from birth and collected cognitive and screen time data (TV, video game, and computer) at ages 11, 15, and 18.…”

Digital media defines modern childhood, but its cognitive effects are unclear and hotly debated. We believe that studies with genetic data could clarify causal claims and correct for the typically unaccounted role of genetic predispositions. Here, we estimated the impact of different types of screen time (watching, socializing, or gaming) on children’s intelligence while controlling for the confounding effects of genetic differences in cognition and socioeconomic status. We analyzed 9855 children from the USA who were part of the ABCD dataset with measures of intelligence at baseline (ages 9–10) and after two years. At baseline, time watching (r = − 0.12) and socializing (r = − 0.10) were negatively correlated with intelligence, while gaming did not correlate. After two years, gaming positively impacted intelligence (standardized β = + 0.17), but socializing had no effect. This is consistent with cognitive benefits documented in experimental studies on video gaming. Unexpectedly, watching videos also benefited intelligence (standardized β = + 0.12), contrary to prior research on the effect of watching TV. Although, in a posthoc analysis, this was not significant if parental education (instead of SES) was controlled for. Broadly, our results are in line with research on the malleability of cognitive abilities from environmental factors, such as cognitive training and the Flynn effect.
