Emotion and Motivation Notes

Emotion and Motivation Overview

  • Definition of Emotions: Emotions are subjective states of being, often influenced by experiences, expressions, cognitive appraisals, and physiological responses.

  • Key Emotions: Surprise, fear, anger, and sadness can change rapidly especially in response to unexpected events.

Theories of Motivation

  • Intrinsic vs. Extrinsic Motivation:

    • Intrinsic Motivation: Driven by internal satisfaction (e.g., pursuing education for personal growth).

    • Extrinsic Motivation: Driven by external rewards (e.g., studying for a degree to obtain a high-paying job).

    • Many motivations are a combination of both intrinsic and extrinsic factors.

  • Overjustification Effect: When external rewards undermine intrinsic motivation (e.g., a hobby turning into work reduces enjoyment).

Theories Explaining Motivation

  1. Instinct Theory: Suggests behavior driven by instincts essential for survival, but lacks consideration for learned behaviors.

  2. Drive Theory: Proposes that physiological needs create psychological drives (e.g., hunger leads to eating) to restore homeostasis.

  3. Optimal Arousal Theory: Motivation is influenced by our need to maintain an optimal level of arousal; performance improves when arousal is at a moderate level.

  4. Maslow’s Hierarchy of Needs:

    • Physiological Needs: Basic survival needs (food, water).

    • Safety Needs: Security, stability.

    • Belongingness and Love Needs: Relationships and social connections.

    • Esteem Needs: Self-esteem, recognition.

    • Self-Actualization: Achieving one's full potential.

Physiological Mechanisms of Hunger and Eating

  • Hunger Regulation: Mechanisms involve contraction of the stomach and hormonal signals (e.g., low blood sugar causes hunger signals to the brain).

  • Satiation Mechanisms: Involves chemical signals (e.g., leptin) that signal fullness when the body has enough energy.

  • Metabolism: Each individual has a metabolic rate affecting caloric expenditure and body weight.

Eating Disorders

  • Obesity: Defined as having a BMI of 30+, leading to health risks like diabetes and heart disease.

  • Anorexia Nervosa: Characterized by restricted eating, leading to dangerously low body weight; severe health consequences.

  • Bulimia Nervosa: Involves binge eating followed by compensatory behaviors like purging; associated with significant health risks.

Sexual Behavior and Motivation

  • Physiological Mechanisms: Involves the hypothalamus and limbic system in regulating sexual motivation and behavior.

  • Research Contributions:

    • Alfred Kinsey: His research shifted public perception of sexuality through empirical surveys.

    • Masters and Johnson: Molded understanding of the sexual response cycle into four phases: excitement, plateau, orgasm, resolution.

Theories of Emotion

  • James-Lange Theory: Emotions follow physiological responses (e.g., you feel fear after shaking due to a threat).

  • Cannon-Bard Theory: Simultaneous physiological response and emotional experience occur independently.

  • Schachter-Singer Theory: Emotions arise from physiological arousal and cognitive appraisal of the context.

  • Appraisal Theory: Emotions are influenced by interpretations and thoughts about a stimulus.

Biological Basis of Emotions

  • Limbic System: Includes the amygdala and hippocampus, influencing emotional processing, memory, and responses to stimuli.

  • Amygdala: Critical in processing fear and other emotional information.

  • Cultural Display Rules: How different cultures express emotions; some cultures engage in suppression regarding negative feelings.

Emotional Regulation

  • Definition: Involves altering emotional experiences through various strategies, both covert and overt (e.g., laughter in stressful situations).

  • Influence of Emotion Regulation: Can significantly affect psychological health; helpful strategies include mindfulness and seeking social support.

  • Definition of Intrinsic Motivation: Intrinsic motivation refers to engaging in an activity for its own sake, driven by internal rewards. Individuals are motivated by personal interest, satisfaction, or the enjoyment of the activity itself. For example, a person may read a book not for external accolades but because they genuinely enjoy reading and learning.

  • Theories Supporting Intrinsic Motivation:

    1. Self-Determination Theory: Proposes that intrinsic motivation is enhanced when three basic psychological needs are satisfied: autonomy (feeling in control), competence (feeling capable), and relatedness (feeling connected to others). Activities that fulfill these needs are likely to boost intrinsic motivation.

    2. Flow Theory: Introduced by Mihaly Csikszentmihalyi, this theory explains how people experience deep engagement and satisfaction in activities that match their skill level with the challenge presented. This state of flow fosters intrinsic motivation since individuals become absorbed and enjoy the process.

    3. Cognitive Evaluation Theory: A sub-theory of Self-Determination Theory that suggests external rewards can impact intrinsic motivation. When individuals perceive external rewards as controlling, their intrinsic motivation may diminish. Conversely, rewards that affirm competence can enhance intrinsic motivation.

  • Strategies to Foster Intrinsic Motivation:

    • Encourage personal goal setting to enhance autonomy.

    • Provide constructive feedback to boost competence.

    • Create opportunities for collaboration to foster relatedness.
