Emotion & Motivation: Theories, Expressions, and Biological Bases

Theories of Emotion

James-Lange Theory: Proposes that physiological responses to stimuli precede emotional experiences. For example, seeing a bear causes a rapid heartbeat, which is then interpreted as fear.
Cannon-Bard Theory: Argues that emotional experiences and physiological responses occur simultaneously but independently. For instance, seeing a bear triggers both fear and physiological changes at the same time.
Two-Factor Theory: Suggests that physiological arousal occurs first, followed by cognitive labeling of that arousal, leading to the emotional experience. For example, seeing a bear causes heart pounding, and labeling that as fear results in the feeling of fear.

Primary Emotions: Include joy, surprise, fear, anger, sadness, and disgust. These emotions are universally recognized across cultures.
Secondary Emotions: Include embarrassment, envy, empathy, pride, shame, and guilt. These emotions are more complex and often arise from social interactions.
Contentment and Distress: Contentment is linked to joy and interest, while distress encompasses fear, anger, sadness, and disgust.

In Ourselves: The facial feedback hypothesis posits that facial expressions can influence emotional experiences. For example, smiling can enhance feelings of happiness.
In Others: Observing someone else's facial expressions can evoke similar emotional responses in us, demonstrating the interconnectedness of emotional experiences.

Amygdala: Acts as the fast pathway for emotional responses, allowing for quick reactions to stimuli.
Cortex: Functions as the slow pathway, providing a more thorough analysis of emotional stimuli, leading to more nuanced emotional responses.

Evolutionary Perspective: Suggests that motivations are shaped by natural selection, driving behaviors that enhance survival.
Drive Reduction Theory: Proposes that physiological needs create drives that motivate behavior to restore homeostasis. For example, hunger drives us to seek food.
Optimal Arousal Theory: Suggests that individuals are motivated to maintain an optimal level of arousal, seeking stimulation when bored and calming down when overstimulated.
Maslow's Hierarchy of Needs: A pyramid of needs ranging from basic physiological needs to self-actualization, indicating that higher-level needs become relevant only after lower-level needs are satisfied.

Biological Motivation: Includes basic needs such as hunger and thirst, regulated by hormones like ghrelin (hunger on) and leptin (hunger off).
Psychological Motivation: Encompasses needs for belonging and achievement, influencing social behaviors and personal goals.

Intrinsic vs. Extrinsic Motivation: Intrinsic motivation refers to engaging in behavior for its own sake, while extrinsic motivation involves performing actions for external rewards.
Overjustification Effect: Describes how external rewards can diminish intrinsic motivation for an activity.
Achievement Motivation: The desire to accomplish goals and experience a sense of success.

Primary Emotional Displays: Facial expressions are the most direct indicators of emotional states.
Display Rules: Cultural norms dictate how and when emotions should be expressed, leading to variations in emotional expression across cultures.
Sincerity in Expressions: There are identifiable differences between sincere and insincere emotional expressions, although people often struggle to distinguish between them.

Voice and Body Language: Both vocal tone and body language convey emotional states, enhancing or contradicting facial expressions.
Emotional Contagion: Emotions can be contagious; observing someone express an emotion can trigger similar feelings in the observer.

Key Terms/Concepts

Emotion: A positive or negative experience associated with a particular level of physiological activity.
Motivation: The internal causes of purposeful behavior.
James-Lange Theory: The theory that feelings are the perception of one’s own physiological responses to a stimulus.
Two-Factor Theory of Emotion: The theory that stimuli trigger a general state of physiological arousal, which is then interpreted as a specific emotion.
Drive-Reduction Theory: A theory suggesting that the primary motivation of all organisms is to reduce their drives.
