Games violentos são inofensivos para maioria das crianças, diz estudo [...]
Patrick Markey, da Villanova University, na Pensilvânia, constatou em um estudo com 118 adolescentes que certos traços de personalidade podem servir para prever que crianças sofrerão influência negativa dos videogames.
Se alguém se irrita, deprime ou zanga facilmente, ou é indiferente aos sentimentos alheios, viola as regras e não cumpre promessas, a probabilidade de que seja hostil depois de jogar videogames violentos é maior.
"As pessoas negativamente afetadas são aquelas com disposição preexistentes que as tornam suscetíveis a mídias violentas como essa." [...]
Acho que é mais complicado que isso:
Furthermore, while a positive relationship was found between early aggression and subsequent TV violence viewing, the effect was not significant. These findings suggest that, while aggressive children may choose to watch more violent TV programming, it is more plausible that early childhood exposure to TV violence stimulates increases in aggression later in adulthood. (Longitudinal relations between children’s exposure to TV violence and their aggressive and violent behavior in young adulthood)
Mas em nota mais positiva, Pamela Kato, do University Medical Center de Utrecht, Holanda, demonstrou em sua pesquisa que jogos especialmente planejados podem ajudar a prevenir ataques de asma e facilitar o combate à dor e o tratamento do diabetes.
Jogos violentos? Também tem aspectos prejudiciais, talvez até para as mesmas coisas, devido ao estresse que pode causar.

Video Games Affect the Brain—for Better and Worse
By Douglas A. Gentile, Ph.D.
July 23, 2009
We hear conflicting reports about how video games affect our brains. One study will suggest that video games help us learn; another might imply that they make young people more aggressive. Douglas A. Gentile argues that how games influence our brains is not an either-or proposition; games can have both positive and negative consequences, and which of these researchers find depends on what they are testing. Gentile proposes that researchers focus their investigations on five attributes of video game design to tease out these disparate effects.
