Document Summary
Embodies the idea that the human mind has no inborn tendencies or inclinations. Cultures are free to vary in any direction on any trait. Humans are born with a bundle of emotional, motivational and cognitive. Culture itself is based on a universal human nature, and is constrained by it adaptation. Behavior is the result of interactions between evolved psychological mechanisms and cultural and environmental influences. What is sociobiology? a school of thought that takes darwin"s theory of evolution and applies it to animal (including human) behavior. Individual learns to fear something associated with a negative stimulus. Amygdala is essential to fear and learning to be fearful. If the response to the second stimulus occurs with only presentation of the first, we have pavlovian conditioning. Naive mouse learns quickly to copy the response of a bitten model in the presence of biting flies. Proximate mechanism: nmda receptors important to neural plasticity. Stathmin gene controls learned and innate fear.
