This body of research, however, is of limited use to clinicians for a range of reasons.7 The most-cited studies are laboratory experiments on college students, generally involving brief exposures to a single violent game. Correlational studies typically involve small, nonrepresentative samples, and assess playing time rather than game content. The terminology is vague, and some researchers use "aggression" and "violence" interchangeably, implying that one inevitably leads to the other. Studies done in the 1980s and 1990s are outdated because of rapidly evolving content and technologies. Recent studies that involve child or adolescent exposure to violent game content represent a tiny fraction of this literature.
