Q

2 types of nuances of resource subdivisions

A
  1. Resource availability vs. patchiness
  2. Resource availability vs. predictability
30
Q

More details on Resource Availability vs. Patchiness

A

While lack of resources would lead to greater aggression, if the resource is evenly distributed there are no incentives to be aggressive and try to fight for resources that can be obtained elsewhere

31
Q

More details on Resource Availability vs. Predictability

A

While lack of resources would lead to lower delayed gratification, if the resources are predictably low, individuals may adopt a planful approach of higher delayed gratification

57
Q

A

They are cultures within cultures

58
Q

How can Subcultures affect similarities between individuals?

A

Cultures in close geographical proximity are more likely to be similar to each other than cultures in different geographical regions due to ecological reasons

59
Q

What causes Cultural Changes?

A

Ecological changes

60
Q

What is Culture-Gene Coevolution?

A

Cultural practices and innovation may exert selective pressure on the genes responsible for adaptations themselves

61
Q

A

An evolved psychological mechanism shaped by natural selection

62
Q

A
  1. Prestige bias/model
  2. Similarity bias/model
  3. Frequency bias/model`
63
Q

What is Prestigious Model?

A

Models who have demonstrated prior skills and success

64
Q

What is Similar Model?

A

Models who are similar to the learner

65
Q

What is Frequency Model?

A

Adopting the beliefs and practices most prevalent in others via conformity

66
Q
