Final answer:
The debate on whether violent video games lead to aggression continues, with studies showing increased aggressive thoughts and emotions after playing, yet little evidence linking such games directly to physical violence or criminal behavior.
Step-by-step explanation:
The potential problems caused by video games, specifically violent video games, have been debated with some researchers suggesting a link to increased aggressive tendencies. Psychologists Anderson and Bushman found evidence for causal linkages between violent video game use and aggression, which include an immediate increase in hostile or aggressive thoughts, aggressive emotions, and physiological arousal. This arousal could increase the likelihood of aggressive behavior.
However, it's important to note that other research indicates scant evidence that violent video games lead to actual physical violence or criminal behavior. The controversy involves whether violent individuals are simply more attracted to these types of games, rather than games causing violent behavior. Multiple factors, including mental health and family life, could play significant roles in a person's propensity for aggression, influence of violent media being just one of them.
