PSYA01H3 Lecture Notes - Lecture 2: Prefrontal Cortex, Limbic System
Document Summary
What is emotion: a positive or negative experience in response to a stimulus and associated with a particular pattern of physiological activity, two - dimensional, valence (positive or negative, psychological arousal (severity) James-lange theory: holds that the stimulus in the environment triggers a physiological response, and that physiological response activates an emotional response, bear -> increased heart rate -> experience of fear. Cannon-bard theory: stimulus activates the physiological and emotional state simultaneously. Two-factor theory (schachter) theory of emotional processing: argues that the stimulus produces a physiological state, and the brain interprets that physiological state emotionally, why is my heart beating fast, oh, because there"s a bear. Major brain structures involved in emotional processing: 2 major neural structures related to emotion, amygdala, prefrontal cortex, amygdala, part of limbic system, quickly processes biologically relevant information, prefrontal cortex, slowly processes information rationally. Emotional regulation: factors to deal with while regulating emotion.
