Motivation and Emotion

Motivation

Motivation refers to the psychological and physiological processes underlying the initiation of behaviors that direct organisms toward specific goals. It is essential for survival and influences both conscious and unconscious actions.

Definition: Motivation is the drive that compels us to act in pursuit of needs or desires.
Instincts: Innate drives that push us to reduce deficits (e.g., thirst, hunger).
Motives: States that energize behavior, such as drinking when thirsty or seeking comfort when lonely.
Example: A behavior can be motivated to complete some sort of goal-directed behavior.

Physiological Aspects of Motivation

Motivation is influenced by physiological mechanisms that regulate bodily needs.

Hypothalamus: Controls hunger and thirst via hormone regulation.
Homeostasis: Maintains internal balance (e.g., temperature, energy).
Example: When hypothalamus senses food deprivation, it triggers hunger.

Physiological Aspects of Hunger

Hunger is regulated by complex interactions between hormones and brain structures.

Ghrelin: Hormone that stimulates hunger.
Leptin: Hormone that signals satiety and reduces hunger.
Example: Leptin levels increase after eating, reducing appetite.

Eating and Cognition

Cognitive factors influence eating behaviors, including social context and learned cues.

Portion sizes: Larger portions can lead to increased consumption.
Social facilitation: Eating with others can increase food intake.
Example: People tend to eat more at parties than when alone.

Other Socioenvironmental Factors on Hunger

Environmental cues and cultural influences also affect eating behaviors.

Food-related cues: Smell, sight, and availability of food can trigger eating.
Culture: Cultural norms shape what, when, and how much we eat.
Example: Americans eat larger portions than French people.

Obesity

Obesity is a complex condition influenced by biological, psychological, and social factors.

Prevalence: Adult obesity in Canada increased from 1970 to 2005; 63% of Canadians over 18 are overweight.
Contributing factors: High-calorie diets, sedentary lifestyles, and environmental cues.
Example: Eating high-calorie foods late at night increases risk.

Belongingness and Love Needs

The Need to Belong

Humans have a fundamental need to form social connections for emotional and physical well-being.

Attachment: Emotional bonds with others, including family and friends.
Social connections: Associated with better health outcomes.
Example: Strong sense of belonging correlates with reduced stress.

Companionate Love

Companionate love is related to tenderness and affection in long-term relationships.

Commitment: Ongoing nurturing of partnerships.
Enduring: Stable and lasting emotional bonds.
Example: Married couples often experience companionate love over time.

Emotions

Understanding Emotional Experiences

Emotions are complex states involving subjective experiences, physiological responses, and behavioral expressions.

Cognitive component: Subjective conscious experience.
Physiological component: Bodily arousal (e.g., heart rate, sweating).
Behavioral component: Overt expressions (e.g., facial expressions).
Example: Fear involves feeling afraid, increased heart rate, and a startled facial expression.

Function of Emotions

Emotions serve adaptive functions, helping us respond to environmental challenges and opportunities.

Preparation for action: Emotions prepare us to act in response to events.
Social communication: Facial expressions convey emotional states to others.
Example: Happiness signals positive social interactions.

Labelling Emotions

Emotions are labeled based on cognitive appraisal and cultural context.

Cultural differences: Cultures vary in how emotions are expressed and interpreted.
Example: Some cultures discourage public displays of sadness.

Emotional Expression: Facial Cues

Facial expressions are universal signals of emotion, but can also be influenced by cultural norms.

Primary emotions: Happiness, sadness, anger, fear, surprise, disgust.
Microexpressions: Brief, involuntary facial expressions that reveal true emotions.
Example: Smiling is a universal expression of happiness.

Theories of Emotion

Several theories explain how emotions arise from physiological and cognitive processes.

James-Lange Theory: Emotions result from physical responses to stimuli.
Cannon-Bard Theory: Emotions and physiological responses occur simultaneously.
Schachter-Singer Two-Factor Theory: Emotions arise from a combination of physiological arousal and cognitive appraisal.
Example: Seeing a snake leads to increased heart rate (arousal) and the thought "I'm afraid," resulting in fear.

Equation (Schachter-Singer Two-Factor Theory):

Emotion in Social Contexts

Emotions are shaped by social interactions and cultural expectations.

Social referencing: Looking to others to interpret ambiguous situations.
Example: Children look to parents for cues on how to react to strangers.

Applications and Research Studies

Capilano Bridge Study

This study demonstrated how physical arousal (crossing a high bridge) can be misattributed to romantic attraction.

Findings: Men approached on the bridge were more likely to call the female interviewer, suggesting arousal was interpreted as attraction.

Facial Feedback Hypothesis

The facial feedback hypothesis suggests that facial expressions can influence emotional experiences.

Example: Smiling can make you feel happier.

Emotion and Dating

Emotional arousal can influence attraction and relationship formation.

Example: Exciting activities on a date can increase feelings of attraction.

Summary Table: Theories of Emotion

Theory	Main Idea	Key Components
James-Lange	Emotion follows physiological response	Bodily arousal, then emotion
Cannon-Bard	Emotion and arousal occur simultaneously	Brain processes, simultaneous response
Schachter-Singer	Emotion = arousal + cognitive appraisal	Physiological arousal, cognitive label
