まとめ
処罰は協力を維持するが、その動機は様々である。この研究では、行動を変えることだけでなく、平等主義が処罰行動を促進する主な要因であり、性格や信念とも関連していることがわかった。
科学分野:
- 行動経済学
- 社会心理学
- 進化心理学
背景:
- 費用のかかる処罰は、人間の協力を維持すると理論化されています。
- 処罰行動の正確な動機は完全には理解されていません。
- 処罰は、協力を促進すること以外にも、結果の均等化や相対的な地位の向上など、さまざまな機能を提供する可能性があります。
研究 の 目的:
- 費用のかかる処罰の様々な動機を区別すること。
- 処罰戦略と個人差(性格、政治的イデオロギー、宗教性)との関連を調査すること。
- 代表的な集団における異なる処罰戦略の普及率を推定すること。
主な方法:
- 処罰の動機を分離するために6つの経済ゲームを利用しました。
- 英国と米国の代表的なサンプル(N=2010)を調査しました。
- 処罰戦略と性格変数、政治的イデオロギー、宗教性との相関を調べました。
主要な成果:
- 観察された最も一般的な戦略は、処罰をしないことでした。
- 処罰を行った個人については、戦略は行動変容の動機よりも平等主義的な動機により一致していました。
- 異なる処罰戦略は、性格特性、社会的選好、政治的イデオロギー、宗教性との相関を示しました。
結論:
- 人間の処罰は多面的であり、複数の機能を提供します。
- 処罰の決定の根底にある動機は、基本的な性格特性と結びついています。
- 個人は自身の処罰戦略についてある程度の認識を持っています。

Timing and Consequences on Behavior
349
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Secondary Motives: Affiliation Motivation and Aggression Motivation

Fundamental Attribution Error
13.7K
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Attribution Theory
13.7K
Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).
