Playing violent video games could make some children more aggressive, according to a new study from the Proceedings of the National Academy of Sciences.

Violent video games are seemingly as popular and as accessible as ever -- a real concern for parents like Jovanka Princivil, of Freeport.

"If you're going around killing and shooting people in the game, I think it desensitizes kids," Princivil says.

The new report finds that there is a correlation among children and young adults between playing violent video games and developing aggressive tendencies. The findings come as no surprise to Dr. Victor Fornari, the director of child and adolescent psychiatry at Zucker Hillside Hospital.

"Certainly, it has to have an impact on social relatedness, on sportsmanship, on fairness," Fornari says.

Experts say part of the challenge for parents is that their often simply unaware of what exactly is occurring in newer, violent games.

Princivil says her 8-year-old son is not allowed to play certain games.
