Anderson and colleagues (2010) have conducted extensive research on the effects of violent video games. Their research suggests

A) no causal link between short-term effects of video game playing and behaviour, but correlational data suggested that long-term exposure results in delinquent behaviour.
B) no causal link between the effects of video game playing and behaviour.
C) a short-term immediate effect on thoughts and behaviour from playing a violent game can be found but no detrimental long-term effects were evident.
D) there is a causal link between violent video game playing and aggressive thoughts, emotions, and behaviour.
E) adults and university students show few effects of violent video game playing but an increase in aggression was seen in children who had aggressive tendencies.

D) there is a causal link between violent video game playing and aggressive thoughts, emotions, and behaviour.
