Document Summary
James-lange theory- proposal that an event first provokes the autonomic arousal and skeletal re- sponses & that the feeling aspect of emotion is the perception of those responses. Pure autonomic failure-condition when output from the autonomic nervous system to the body fails. Panic attack-period marked by extreme sympathetic nervous system arousal. Behavioral inhibition system (bis)- right brain hemispheric activity, which increases attention and arousal, inhibits action, and stimulates emotions such as fear and disgust. Behavioral activation system (bas)- left brain hemispheric activity marked by low to moderate auto- nomic arousal and a tendency to approach, which could characterize either happiness or anger. Limbic system-interlinked structures that form a border around the brainstem. By one definition, emotion includes cognitive evaluations, subjective changes, autonomic and neural arousal, and impulses to action . One definition of motivation is an internal process that modifies the way an organism responds to a cer- tain class of external stimuli .
