Abstract
ABSTRACT In this study, I use a representative survey from the German Twin Family Panel (N = 5,472) to examine the extent to which genetic and environmental factors account for time spent playing video games on personal computers and gaming consoles. Results show that genetic variation among twins explains a non-trivial amount of variation in video game play. Through ACE modeling techniques, I find that between 25% to 39% of the total variance in time spent playing video games can be attributed to shared genetic traits with the remainder explained by shared environmental factors (e.g., parenting and culture) and environmental attributes unique to individuals. This study and its findings provide a starting point for future genetic and neurological research on video game use and effects.
