Syllabus: Why Do People Harm Others—and What Can Reduce It?
Apply the measurement review to the noise task, and distinguish the anger results from the aggression results.
Why you’re reading it. Test an intuitively appealing claim against the actual experimental comparisons.
A question to consider. Would these results justify replacing all opportunities to discuss anger with silence? Explain the additional assumptions that conclusion would require.
Why this reading
The idea that aggressive activity releases anger makes a testable prediction. This experiment contrasts thinking about an insulter, thinking about fitness, and sitting quietly, allowing readers to examine what each comparison establishes.
Before you read
Rumination means repeatedly dwelling on the provocation. Catharsis is the proposed reduction of anger through its expression. After insulting feedback, participants either hit a punching bag under different instructions or waited. Anger ratings and chosen noise blasts were separate outcomes.
Read for
- Identify what changes between the two punching conditions and between punching and waiting.
- Compare anger with the noise-task results, including the nonsignificant comparisons.
- Distinguish a challenge to catharsis from a claim about every form of emotional expression.
Consider afterwards
- Which additional condition would help separate the physical activity from the focus of attention?
- What would establish whether the effects extend beyond the next laboratory task?
Editorial context
Rumination produced more aggressive responding than the quiet control. The distraction condition did not differ significantly from either on that outcome. These student laboratory results do not show that disclosure, assertiveness, or exercise is generally harmful. The later Kjærvik and Bushman synthesis broadens the arousal question; its outcome definitions also require attention.
