Child’s play? Assessing the bidirectional longitudinal relationship between gaming and intelligence in early childhood

This study investigated the longitudinal relationship between children’s digital game use and fluid and crystallized intelligence. Specifically, this study examined whether digital games affect children’s fluid and crystallized intelligence (an effects perspective), whether children with higher levels of fluid or crystallized intelligence are more attracted to digital games (a selection perspective), or whether evidence supports a reciprocal relationship between digital game play and intelligence. Using data from 934 children aged 3 to 7 years (52% girls) across four waves with one-year intervals, our evidence for fluid intelligence indicates partial support for the effects perspective and no support for the selection perspective. For crystallized intelligence, our findings did not reveal any significant relationship with digital game use. The results suggest that digital games can move the needle for fluid intelligence, but more insight is needed to identify how this effect occurs, in which situations, and for which children this is most likely.
