PSC 001 – Lecture 14 – Emotions and Motivations
● What Are Emotions?
○ Emotion: Feelings or affect that involve:
■ Subjective evaluation
■ Physiological processes
■ Cognitive appraisals
○ Primary Emotions
■ Innate, evolved, and universal:

■ Two dimensions:
● Valence: How unpleasant vs. pleasant
● Activation: How arousing
○ Arousal: Physiological activation or increased
autonomic responses
● Autonomic Nervous System fight or flight response (not only fear)
● The Amygdala
○ Processes emotional significance of stimuli & generates immediate
reactions
■ Fear
○ Critical for emotional learning (reason why some memories have
emotions)
■ Improves long-term memory
○ Can’t learn fear conditioning if damaged
● Frontal Lobes
○ Prefrontal cortex (PFC):
■ Important for experiencing and expressing emotions
■ Important for regulating emotions
● Some Big Questions

Document Summary
Psc 001 lecture 14 emotions and motivations. Autonomic nervous system(cid:3450) (cid:3247)fight or flight(cid:3248) response (not only fear) autonomic responses. Processes emotional significance of stimuli & generates immediate reactions. Critical for emotional learning (reason why some memories have emotions) Interpretation of physical changes leads to emotion experience. Stimulus (cid:3450) (cid:3449) arousal (cid:3450) emotions (fear) Facial feedback: expressing a specific emotion can lead to the subjective experience of that emotion. We label emotions based on how we interpret the situation. Stimulus - arousal - label - emotion. Excitation transfer: residual arousal caused by one event is transferred to a new stimulus. Our faces communicate our emotions to others. Specific facial muscles in expressions can identify emotions. Facial action coding system ( every human emotion) We can adjust emotional expressions to fit the social context. Display rules: rules learned through socialization that dictate which emotions are suitable to given situations.
