Altruism01:03

Altruism

41.9K
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.

Social Proof00:52

Social Proof

30.5K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Inclusive Fitness

36.7K
Most altruistic behavior—in which one animal helps another at a cost to themselves—occurs between relatives. Scientists think these altruistic behaviors evolved because they increase the inclusive fitness of the animal providing help.

Robbers Cave04:49

Robbers Cave

14.6K
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...

Impact of Groups on Individuals01:28

Impact of Groups on Individuals

170
Groups play a fundamental role in shaping individual behavior, as they establish norms that guide interactions and decision-making. Social psychology examines how individuals conform to group expectations, often adjusting their attitudes and actions to align with group norms. These norms can be formal, such as workplace policies, or informal, such as unspoken social expectations within a fraternity.Conformity and Social InfluenceConformity arises when individuals modify their behaviors or...

Summary

Chimpanzees exhibit prosocial behavior by sharing valuable resources at personal cost. This altruistic tendency varies significantly between different chimpanzee communities, indicating group-specific sociality.

Area of Science:

  • Primate behavior
  • Evolutionary anthropology
  • Social cognition

Background:

  • Chimpanzees display cooperative behaviors in their natural habitats.
  • The extent to which they provide benefits to others and if this varies across communities remains unclear.

Purpose of the Study:

  • To investigate whether chimpanzees engage in prosocial behavior by providing valuable resources to group members.
  • To determine if the level of prosocial behavior differs among chimpanzee communities.

Main Methods:

  • A resource-donation experiment was conducted with chimpanzees, allowing for free partner choice.
  • Chimpanzees' prosocial acts were observed under conditions where group members could profit (test) versus when resources were inaccessible (control).

Main Results:

  • Chimpanzees increased prosocial acts over the study period.
  • Prosocial behavior was more frequent and sustained when recipients could profit.
  • A significant group-specific variation in prosocial behavior was observed, correlating with social tolerance.

Conclusions:

  • Chimpanzees intentionally engage in prosocial behavior towards group members.
  • Group-specific sociality is a crucial factor in understanding the evolution of prosociality in nonhuman animals.
