"The research on computer and videogames and children has received considerable research attention in recent years. The earliest work examined the simple relationship between computer game play and aggression, whereas more recent research has utilized an experimental approach in order to test issues of causality between the two. For example, early research found a correlation between overall videogame exposure and real-world aggressive behavior in children from 4th to 12th grade (Dominick, 1984; Fling et al., 1992; Lin & Lepper, 1987). Early experimental work (Cooper & Mackie, 1986; Irwin & Gross, 1995; Schutte, Malouff, Post-Gorden, & Rodasta, 1988; Silvern & Williamson, 1987) also found some support for the notion that violent videogame content can increase aggression; however, technological advances in the field of electronic gaming have rendered much of the very early research in this area all but obsolete. What does more recent research tell us? Violent videogames can influence aggressive cognitions (Anderson et al., 2004; Anderson & Dill, 2000; Kirsh, 1998; Tamborini et al., 2001), as well as aggressive affect, leading to feelings of hostility (Anderson & Dill, 2000; Tamborini et al., 2001), and have been found in survey research to be associated with aggressive delinquent behavior, even after controlling for aggressive behavior (Anderson & Dill, 2000; Anderson & Murphy, 2003; Anderson et al., 2004)."
