Document Summary
Psyc 304: chapter 15 emotions, aggression and stress. Defining emotion: 4 aspects of emotion, physiological arousal: displays of somatic and autonomic responses, facial expressions. Emotional reactions help us respond quickly to emergency event: motivational programs: coordinated responses designed to solve specific tasks/achieve specific goals, generated by distinct brain systems, actions: typically, emotions cause us to do something. Specific behaviours designed to achieve motivational goals: feelings: subjective labels placed on an emotional state. Humans experiences all 4 aspects, in animals, we can only assess 1-3. Disgust: 4-8 months: anger (frustration) and surprise, fear. Better understanding of the world around them: 18-24 months: self-awareness develops; ability to predict emotions of others embarrassment, empathy, envy, 2-3 years: become able to evaluate behaviour against a standard. Emotions such as pride, shame and guilt emerge. Development of latter emotions parallels development of frontal lobe functions. Facial expressions of emotions: basic expressions common across many cultures; no specific training required to identify them.
