Longitudinal studies investigating the relationship of aggression and violent video games are still scarce. Most of the previous studies focused on children or younger adolescents and relied on convenience samples. This paper presents data from a 1-year longitudinal study of N � 276 video game players aged 14 to 21 drawn from a representative sample of German gamers. We tested both whether the use of violent games predicts physical aggression (i.e., the socialization hypothesis) and whether physical aggression predicts the subsequent use of violent games (i.e., the selection hypothesis). The results support the selection hypotheses for the group of adolescents aged 14 to 17. For the group of young adults (18 –21), we found no evidence for both the socialization and the selection hypothesis. Our findings suggest that the use of violent video games is not a substantial predictor of physical aggression, at least in the later phases of adolescence and early adulthood. The differences we found between the age groups show that age plays an important role in the relationship of aggression and violent video games and that research in this area can benefit from a more individu- alistic perspective that takes into account both intraindividual developmental change and interindividual differences between players.

From the earliest investigations into the rela- tionship of video game1 use and aggression in the 1980s (Cooper & Mackie, 1986; Dominick, 1984; Silvern & Williamson, 1987; Winkel, Novak, & Hopson, 1987) until today, hundreds
of experimental and correlational studies have been conducted. Despite the large number of studies, the debate about the link between video games and aggression is ongoing, not only in politics and the mass media, but also within academia (Bushman & Huesmann, 2014; Elson & Ferguson, 2014a, 2014b; Krahé, 2014; War- burton, 2014). While all of the available meta- analyses (Anderson et al., 2010; Ferguson, 2007; Ferguson & Kilburn, 2009; Sherry, 2001, 2007) found a relationship between aggression and the use of (violent) video games, the size and interpretation of this connection differ largely between these studies; as do the defini-
1 We use the term video games as an umbrella term that includes all types of digital games, whether they are played on a PC, home consoles, handhelds, or mobile devices. We decided to use “video game” because it is the most common term in the literature and it is easier to read than the composite “computer and video games” or the more aca- demic denomination “digital games.”
