Document Summary
As opposed to the body peripheralist vs. centralist models: peripheralist view peripheral nervous system is the source of emotion. William james = peripheralist: centralist view the brain is the underlying source. Historically these models have been pitted against each other . Three-part soul: reason is found in the head, chest is the locus of noble emotion (courage, belly is the locus of based emotion (lust) Body and brain responsible for distinct processes: 1. Filters air and purifies it yielding vital spirits to drive body (motor activity) but not pure enough for psychological processes. Animal spirits give rise to psychological processes: 2. The brain is an important source for emotionality and cognition. Pain, pleasure, and complex emotions result from vibrations in the brain: different locations in the brain vibrate. Emotional conditioning is a result of fusion: Co-activation of brain regions that become physiologically fixed due to repeated exposure to two stimuli.
