Final answer:
Malamuth (1981, 1989) discovered a link between exposure to media violence and aggressive and sexually aggressive behavior.
Step-by-step explanation:
Malamuth (1981, 1989) is a researcher who conducted studies on the effects of exposure to media violence on aggression and sexual aggression.
In his research, he discovered that individuals who are exposed to violent media are more likely to exhibit aggressive and sexually aggressive behavior compared to those who are not exposed to such media.
For example, one of Malamuth's studies found that male college students who watched a sexually violent film were more likely to express acceptance of sexual aggression and exhibit aggressive behavior towards women.
Therefore, Malamuth's research demonstrates a link between exposure to media violence and aggressive and sexually aggressive behavior.
