Document Summary
Key part of emotional experience: detect emotional item, analyze, and respond. Brain shows emotion dependent responses in about 150 ms of seeing/hearing. Initial reaction is to tag/highlight stimulus that lead to the observable behaviours we think of as emotional responses. Nervous system needs to prep your body to make a movement in response to emotion. Threatening emotional stimuli trigger an increase in activity in brain areas related to planning movement and in several regional of spinal chord. Frontal lobes receive information from amygdala and from sensory areas whose activity is influenced by amygdala. Frontal lobes have access to highly detailed information about stimulus/situation: must determine whether the instinctive emotional response produced by earlier stages of processing is best for that given situation. James-lang theory of emotion: suggests that our psychological reactions to stimuli precede the emotional experience: i. e. subjective feelings follow physiological responses, claims that feeling of fear is determined by how your body responds.
