Lecture_09_Prosocial Behaviors Flashcards
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
