Lecture_09_Prosocial Behaviors Flashcards
(48 cards)
Prosocial Behavior
Any act performed with the GOAL OF BENEFITTING another person
- Depends on the goal, not the effect (Based on intention)
- The individual benefitting from prosocial behavior is not part of the definition: Helping an individual who does not want to be helped
Altruism
- Helping purely out of the desire to benefit someone else
- With no benefit (and often a cost) to oneself
- The key is motivation to help
Semantic Confusion about Altruism
- If a person is rewarded
- When others are around
Reciprocity
Exchanges with others for mutual benefit
- Exchange the same thing
- Exchange the different things
Individuals or groups help each other in the same way
A chimpanzee grooms a second chimpanzee, and the second chimpanzee grooms the first
One thing can be exchanged for a
different thing
I help you move to a new apartment and later you help me with my work
- More common among humans
- Training monkey to use tokens
3 Motives for Prosocial Behavior
- Evolutionary Psychology
- Social Exchange Theory
- Empathy and Altruism
Evolutionary Psychology
The application of the principles of evolutionary biology to the field of psychology
- A meta-theory, or perspective
- Some cognitive mechanisms and behaviors are adaptations
Adaptation
Products of natural selection that helped our ancestors survive and reproduce
Natural Selection
Mutations -> to changes in the structure of an organism -> affect behavior and cognition
Levels of Analysis in Altruism
- Ultimate/distal causation
- Proximate causation
Ultimate/distal causation
WHY
Evolutionary forces acting on mind and behavior
- Kin selection
- Reciprocal altruism
- Costly signaling
Proximate causation
HOW
Immediate causes such as situations and physiology
Empathy-altruism hypothesis, social exchange theory
A Confusion Between Levels of How Natural Selection can Explain Altruism
- Ultimate causation: Altruism is an evolved mechanism that helps unrelated individuals survive and reproduce at the cost of our own ability to survive and reproduce, then altruism cannot exist
- Proximate causation: But people can still be altruistic in other ways.
- Their culture or religion can drive them to sacrifice.
- People can genuinely intend to help in situations where that help is unlikely to benefit them
Kin Selection
Inclusive fitness theory
- Organisms can spread their genes by helping genetic relatives with whom they share genes
- Favor altruistic acts directed toward genetic relatives
Criticism of Kin Selection
We can’t perceive whether others are related to us
- Proximate level: people they have known for many years, look like people who they have known, familiar
Reciprocal Altruism
- Natural selection can favor behaviors where an organism temporarily hurts its ability to survive and reproduce by helping another organism
- For this to happen, the second organism needs to be more likely to help the first organism in the future
2 Conditions for Reciprocal Altruism
- A way to detect cheaters who receive help but do not return the favor
- Many interactions between the organisms so that cheating is not an effective strategy
Reciprocal Altruism in Animals
- Vampire bats feed unrelated vampire bats who are then more likely to feed them back in the future
- Cleaner fish are small fish that eat dead skin and parasites from the mouths of larger fish
- The cleaning helps the larger fish, which does not swallow the cleaner fish and protects it from predators
Is reciprocal altruism an example of altruism?
Yes
- Reciprocal altruism does not require for the helper to be consciously aware that they expect the favor to be returned
- People with minds shaped by reciprocal altruism may still just help others out of the goodness of their hearts:
Punishment for Fail Reciprocity
- Loss of relationships and future help
- Gossip that damages their reputations and relationships
Costly Signaling
Organisms often want to signal their desirable characteristics to others
- Only individuals possessing the desirable characteristic can afford to communicate it
- When we help others, we show that we:
1) have resources that we can afford to give others
2) are willing to sacrifice these resources to help others
3) value our place in our group and our relationship with people in the group
Evidence suggesting that prosocial behavior is a costly signal
- Donating money when observed by others -> improve a person’s reputation
- The presence of others increases altruism, generosity, and cooperation
- When people are more visible and less anonymous, they cooperate more with other people
Social Exchange Theory
prosocial behavior, is shaped by our desire to maximize rewards while minimizing our costs
