Document Summary
Principle of psychic determinism: everything that we do is caused by a mental event (psychological) that comes beforehand. Freud = possible causes are unconscious events. Whenever you draw a time frame around an event of observation, you"re including some possible causes but also excluding others. Darwin"s theory is not a theory about the origin of life forms, but rather about the process of change over time (evolution) Ontogeny: psychologists look for ontogenetic causes (focus on development of the individual) how? . Phylogeny: psychology ignores ultimate causation (address adaptive significance of a trait or behaviour over evolutionary time) why? . Scientific observations pre-darwin: biodiversity, the earth is old. Thomas maltus essay on principle populations competition for resources: darwin = descendants of a common ancestors accumulated all the diverse modifications and adaptations that allowed them to survive, there"s a selective feature for adaptive traits. Changes over time occur due to differential reproductive success.
