Robbers Cave04:49

Robbers Cave

14.4K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Social Exchange Theory

35.1K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Area of Science:

  • Social Psychology
  • Behavioral Economics
  • Moral Decision-Making

Background:

  • The reciprocity norm dictates adjusting behavior to others in social interactions.
  • Self-interest prioritizes personal goals, considering reciprocity only if it aligns.
  • Conflicts between reciprocity and self-interest can be intensified by competitive pressures.

Purpose of the Study:

  • To investigate which principle, reciprocity or self-interest, dominates in a competitive context when they conflict.
  • To examine the influence of competition degree on this conflict.
  • To test if affective states and moral beliefs mediate the decision-making process.

Main Methods:

  • 276 participants engaged in a two-stage simulated interaction with a fictitious opponent.
  • Opponent's behavior varied (selfish, fair, altruistic).
  • Participants faced a moral dilemma where reciprocating conflicted with personal goals; competition degree was manipulated.

Main Results:

  • Reciprocity was the primary influence on decision-making.
  • Participants prioritized reciprocal behavior even at the expense of personal interest, irrespective of competition level.
  • Affective states and beliefs were altered by the manipulation but did not mediate the observed effects.

Conclusions:

  • The norm of reciprocity is a powerful driver of social behavior, often overriding self-interest in competitive scenarios.
  • Contextual factors like competition may not significantly alter the precedence of reciprocity.
  • Future research could explore other potential mediating factors beyond affect and beliefs.
