the statements that there is probably an “infinite” number of stimuli that could cause aggression or aggressive
thoughts in a person (e.g., a picture of a gun), and that his selection of violent video games was “largely a

FN18. The State also relies on a 2003 study on general media violence by Dr. Anderson, which contains a
three-page section on violent video games and reflects the conclusions and shortfalls of the 2004 meta-
analysis. Craig A. Anderson et al.,
The Influence of Media Violence on Youth,
4 PSYCHOLOGICAL
SCIENCE IN THE PUBLIC INTEREST 81, 90-93 (2003). For example, the study states that “[t]here are no
published longitudinal surveys specifically focusing on effects of violent video games on aggression.”
The State also relies on a study of the effects of video game violence on adolescents, conducted by Dr. Douglas Gen-
tile, which studied eighth and ninth graders and concluded that “[a]dolescents who expose themselves to greater
amounts of video game violence were more hostile” and *964 reported getting into more arguments and fights and
performing poorly in school. Douglas A. Gentile et al.,
The effects of violent video game habits on adolescent hostility,
aggressive behaviors, and school performance,
27 J. ADOLESCENCE 5 (2004). The extent to which this study sup-
ports the State’s position is suspect for similar reasons as Dr. Anderson’s work. First, this study states that due to its
“correlational nature” it could not directly answer the following question: “Are young adolescents more hostile and ag-
gressive because they expose themselves to media violence, or do previously hostile adolescents prefer violent me-
dia?” Second, this study largely relates to the player’s violent or aggressive behavior toward others-which, as noted
above, is not the interest relied on by the State here-rather than the psychological or neurological harm to the player.
Moreover, the study glaringly states that “[i]t is important to note … that this study is limited by its correlational nature.
Inferences about causal direction should be viewed with caution
” (emphasis added). Finally, Dr. Gentile’s study sug-
gests that “[a]dditional experimental and longitudinal research is needed.”
Additionally, the State relies on a study by Dr. Jeanne Funk for the proposition that video games can lead to desensi-
tization to violence in minors. Jeanne B. Funk et al.,
Violence exposure in real-life, video games, television, movies,
and the internet: is there desensitization?,
27 J. ADOLESCENCE 23 (2004). Like the others, this study presents only
