Gene behind kids’ love for violent TV shows?

Gene Behind Kids Love Violent TV Shows

Ever wondered why certain kids like violent TV and video games more than others? Scientists now say they were just born that way.

A specific variation of the serotonin-transporter gene is linked to children who engage in increased viewing of violent TV and playing of violent video games, a new study has found. Researchers analyzed survey data of 1,612 Dutch parents of children aged 5-9.

The parents noted how much violent TV programming their children viewed, as well as how often they played violent video games.

DNA samples collected at the children’s birth were then analyzed to determine a certain gene variant.

The researchers found that children that had the specific variant of the serotonin-transporter gene on average consumed more violent media and displayed more behavioural patterns related toattention deficit hyperactivity disorder (ADHD).

However, these links are subtle and more factors can influence these behaviours in children.
