Document Summary
Basic universal emoions - carol izard - people from diferent cultures generate and recognize same basic emoional expressions. 7 easy to idenify: anger, happiness, disgust, surprise, sadness, fear. Each emoion = several set of facial muscles. James-lange says that ans acivaion comes before emoion is experienced. Cannon-bard says brain controls emoion, the ans response is merely coincidental to the emoional state. Facial-feedback hypothesis states that expressing a facial emoion leads to physiologically feeling that emoion. James-lange: ans before emoion-emoional response occurs ater ans response. Peripheral nervous system determines emoional state (peripheral responses communicate a quality of the emoion to the brain, which then interprets it) Each emoion has its own speciic patern of ans arousal, brain reads patern to interpret current emoional state. Event in environment (seeing a iger) triggers behavioural (muscle acivaion), autonomic (increased heart rate and blood pressure) and endocrine (release of stress hormones) responses. Feedback from response produces feeling of fear.
