Answer: Hitting the punching bag will make Shawna feel more aggressive toward her ex-boyfriend.
Explanation:
Catharsis refers to a reduction in the impulse to act aggressively, which is believed to be a result of an imaginary, perceived, or real act of violence. The first concept of catharsis combined two steps: a reduction of physiological arousal, followed by a decrease in aggressiveness. Later, that concept was questioned by studies that suggested that getting involved in or even observing aggression may increase feelings of aggression.
