Q

Empiricism

A

View that we obtain knowledge through observable facts and sensory observations.
Believe behavior is measurable, the mind is not. Therefore reality doesn’t always apply.

Q

Connection between Psychology and Science

A

Scientists study through systematic observation and experiment. This is Empirical.

The results are used to make theories that predict new phenomena. The theories are biased off logic and reason. This is rationalism.

aspects of an environment that individuals living together (e.g., in a family household) do not share and that therefore cause them to become dissimilar to each other.

Occur through “survival of the fittest”. Genes that code for characteristics related to survival and reproductive success are passed on. Has a lot of misconceptions

60
Q

Explain the adaptive functions of:
Dominance Hierarchies

A

Have to fight to be at the top. those at the top get first pick of food, resources and mates. Their bloodline is more likely to be passed on. This means the species will get stronger

61
Q

parental investment theory

A

a theory that stresses the evolutionary basis of many aspects of parental behavior, including the extensive investment parents make in their offspring.
