Problem 9 - Entrance Test

A new study claims that children who play violent video games are more likely to exhibit aggressive behavior. The study surveyed 1,000 children, asking them about their gaming habits and observing their behavior in controlled play sessions. However, the study relied on self-reported gaming data, and the observed aggressive behavior was limited to minor incidents like pushing and verbal outbursts.

Correct: E

The study concludes that violent video games *cause* aggressive behavior. The most significant flaw in such a correlation-causation argument is often the possibility of reverse causation. Option E directly addresses this by asking if children who are *already* aggressive are more likely to play violent video games. If this were true, the observed correlation would be explained by pre-existing aggression leading to gaming choices, rather than the games causing aggression, thus severely undermining the study's conclusion. Option A (age) is a demographic detail but doesn't challenge the causal link as fundamentally. Option B (game type) refines the scope but not the causality. Option C (parental attitudes) introduces another factor, but less directly challenges the video game-aggression link than reverse causation. Option D (definition outside study) is less critical as the study's observations were limited to controlled sessions.
