Unit 6 Motivation, Emotion, and Personality
Core Motivation Theories
These are the big-picture ideas behind why we do anything—whether it’s eating, studying, or seeking adventure.
Drive-Reduction Theory
You’re motivated to fix imbalances in your body.
Driven by needs (hunger, thirst) → creates a drive → behavior fixes it → back to homeostasis.
Example: Hunger makes you go get food.
Arousal Theory + Yerkes-Dodson Law
Motivation comes from finding the right amount of stimulation (not too bored, not too stressed).
Yerkes-Dodson Law: Best performance happens at moderate arousal.
Easy tasks benefit from higher arousal
Difficult tasks need lower arousal
Example: A little test anxiety helps focus, but too much shuts you down.
Cognitive & Social Approaches to Motivation
These build more on mental processes and goal-directed thinking. Research has shown that individuals who set specific and challenging goals tend to perform better and stay motivated, as this creates a clear direction and purpose for their efforts.
Self-Determination Theory
Motivation comes from 2 forms.
Intrinsic: doing something because you enjoy it (e.g., drawing for fun)
Extrinsic: doing it for a reward or to avoid punishment (e.g., studying for a prize)
Incentive Theory
This explains how external rewards (or punishments) drive behavior.
Positive incentives: motivation to do something (e.g., praise, money)
Negative incentives: motivation to avoid (e.g., fines, scolding)
Stronger or more meaningful incentives usually increase motivation.
Biological vs Learned Behaviors
This is about instinct vs learning—focus on animals vs humans.
Instinct Theory
Instincts: hardwired behaviors in animals (e.g., bird nests, salmon swimming upstream)
Humans don’t rely on instincts the same way, but may show basic patterns like:
Rooting reflex in babies
Fear of loud noises
Human behavior is often learned, flexible, and shaped by culture and experience.
Motivational Conflict (Lewin’s Theory)
Sometimes motivation is shaped by how we deal with choices—weighing pros and cons. Expect example-based questions here!
Approach-Approach Conflict: Choosing between two good options (e.g., two colleges you love)
Avoidance-Avoidance Conflict: Choosing between two bad options (e.g., vacuum or do homework)
Approach-Avoidance Conflict: One choice has pros and cons (e.g., a great job offer far from home)
Sensation-Seeking Motivation
Some people are wired to chase new or risky experiences. This helps explain behaviors like traveling, extreme sports, or rule-breaking.
Experience Seeking: Desiring new ideas or lifestyles
Thrill and Adventure Seeking: Craving excitement (e.g., skydiving)
Disinhibition: Enjoying “loosening up” in social settings or risky behavior
Boredom Susceptibility: Getting restless or irritated with repetition
Eating as Motivated Behavior
Eating is driven by a mix of internal signals from the body and external cues from the environment.
Hypothalamus regulates homeostasis
Monitors glucose (sugar) in our blood
Ventromedial hypothalamus (VMH) acts as an off-switch leading to a feeling of satiety
In experiments, when destroyed, an animal eats
ravenously
Lateral hypothalamus (LH) acts like an on switch, leading
to feelings of hunger
In experiments, when destroyed, an animal stops eating
almost entirely
Dual-center theory - The VMH & LH work together to defend a set point of body weight, like a thermostat
Biological Factors that affect eating include hormonal signals such as leptin and ghrelin, which help regulate hunger and satiety, as well as the body's metabolic rate and its nutritional needs. Additionally, factors such as genetics and brain chemistry can influence individual eating patterns and preferences.
Ghrelin: triggers hunger
Leptin: signals fullness
Both are regulated by the hypothalamus (via pituitary gland)
Environmental & Psychological Factors that affect eating habits include stress, social influences, food availability, and personal emotions. Additionally, cultural norms and learned behaviors also play a significant role in shaping our dietary choices and preferences.
Food availability — we eat even if not hungry
Time of day — we eat out of routine
Social settings — people eat more in groups
Belongingness as Motivation
Humans are naturally driven to form connections—relationships improve mental and emotional health.
Feeling accepted drives behavior (joining clubs, following group norms)
Social connection = better health and well-being
Lack of belonging can lead to anxiety or demotivation
How Emotion Works
Emotion is more than just feeling something—it’s a combo of body reactions, thoughts, and behavior, shaped by both what's going on inside you and around you.
What Is Emotion?
Emotion (aka affect) = a complex mental/physical state that includes:
A subjective feeling (happy, scared, etc.)
Physical responses (like heart rate, facial expression)
Behavior (like running, smiling, crying)
Emotions are shaped by:
Internal factors (thoughts, memories, physiological responses)
External factors (environment, social situations)
Theories of Emotion
You won’t need to name-drop the specific theory names on the AP Exam—but you should understand the basic thought process behind each category.
Sequential Theories:
Arousal comes first, emotion comes after.
Example: You see a snake → heart rate increases → you feel fear.
Simultaneous Theories:
Arousal and emotion happen at the same time.
Both body and emotion kick in together when facing a stimulus.
Cognitive Labeling Theories:
You feel arousal first, then label it consciously, and then feel the emotion.
Example: You’re sweating → you think, “This is because I’m anxious” → you feel anxious.

Facial Feedback Hypothesis
Your facial muscles can influence your emotional state.
Smiling a lot can make you feel happier.
Frowning may intensify sadness.
Ties into theories that say physiology comes before conscious emotional experience.
Important note: research shows mixed results—it's still debated.
Emotions & Awareness: Broaden-and-Build Theory
The broaden and build theory helps explain how emotions influence how we think and behave in the long term, not just in the moment.
Positive Emotions
Broaden your thinking → more creativity, problem-solving, learning.
Encourage exploration, social connection, and personal growth.
Build long-term resources (mental, social, emotional).
Negative Emotions
Narrow focus → useful for survival reactions (like fight-or-flight).
Prioritize short-term protection at the expense of long-term goals.
Heighten stress and reduce flexibility in thinking.
Big Picture: Positive emotions help us grow beyond the moment. Negative ones help us survive the moment.

Are Emotions Universal?
There are some emotions that people across cultures seem to recognize—but not everything is a one-size-fits-all.
Universal Emotions
Research (like Paul Ekman’s work) shows six emotions are likely universal:
Happiness
Sadness
Fear
Anger
Surprise
Disgust
These are thought to be evolutionary tools:
Fear = escape danger
Disgust = avoid toxins
Happiness = bond with others
Note: While many studies support this, not all research agrees. It's a debated topic.
Culture & Emotional Expression
Culture doesn’t just shape how we act—it shapes how we feel and show our feelings.
Display Rules
Social norms that tell people when, how, and if to express emotion.
Vary by culture, gender, age, social class
Example: Some cultures value emotional control; others value openness
Example: Men may be discouraged from crying in public in some societies
Elicitors
Triggers for emotion (events, interactions, signals)
Vary across cultures and individuals
Example: Public criticism might elicit shame in one culture and anger in another
What causes an emotion is often just as culturally specific as how it's expressed
Emotional expression is also a way to stay bonded with your social and cultural group—so expression rules may serve a bigger purpose than just personal preference.
What Emotions Do to You
Emotions affect:
Focus and decision-making
Relationships
Coping strategies
Application Examples:
A student feels anxious before a test → studies harder (or shuts down)
Joy after success → more motivated to try again
Many theories suggest cognitive labeling—or how we interpret a situation—shapes the emotion that follows.
Health Psychology: What It Is and Why It Matters
Health psychology is the study of how mental, emotional, and behavioral factors influence physical health and overall wellness.
Quick Facts:
It looks at how thoughts, emotions, and actions affect your body.
Focus areas in health psychology:
How habits like sleep, exercise, and diet impact physical health.
How emotions like stress or anxiety can lead to illness or slow recovery.
How mental states (like depression or stress) interact with physical health (such as immune functioning or heart disease).
Supporting treatment plans by helping people follow medical advice.
Promoting public health through behavioral change (e.g., anti-smoking campaigns).
In short: Health psychology helps explain the mind-body connection, and how improving one can improve the other.
Stress: What It Is and Why It Matters
Stress plays a big role in mental and physical health outcomes. Understanding how it works is key to managing it effectively.
Key Terms:
Stress: A response to a demand or threat.
Stressors: Any event or condition that triggers a stress response.
Effects of Stress on the Mind and Body:
Weakens immune system → more likely to get sick.
The effects are linked to:
Hypertension
Headaches
Fatigue
Anxiety
Depression
Difficulty concentrating
Types of Stress:
Eustress: Good stress that can motivate and focus you (e.g., prepping for a big game).
Distress: Bad stress that feels overwhelming.
Sources of Stress:
Traumatic events – sudden, significant experiences (e.g., loss of a loved one).
Daily hassles – small, everyday annoyances (e.g., traffic, homework).
ACEs (Adverse Childhood Experiences) – early trauma can affect physical and mental health long-term.
How the Body Reacts to Stress
The body doesn’t just "feel" stressed—there’s a full biological and emotional chain reaction.
General Adaptation Syndrome (GAS) – Hans Selye
Alarm: Initial reaction—body kicks into fight, flight, or freeze mode.
Resistance: Body remains on high alert to manage the stress.
Exhaustion: If stress continues too long, body runs out of energy → more likely to get sick.
Remember: Prolonged stress puts both your body and mind at risk.
Tend-and-Befriend Response
An alternative to fight-or-flight, especially common in women.
Involves:
Tending: Caring for yourself or others in response to stress.
Befriending: Reaching out to others for emotional support.
This response builds social bonds during tough times—different, but just as useful.
Coping Strategies: How People Deal with Stress 🛠
How you cope with stress can shape whether it helps you grow or drags you down.
Tackles the source of stress directly.
Best for situations you can change or control.
Examples:
Making a schedule
Asking for help
Solving the issue head-on
Emotion-Focused Coping
Focuses on managing emotions rather than fixing the problem.
Useful when the problem can’t be changed.
Examples:
Breathing exercises or mindfulness
Talking to a supportive friend
Using medication for anxiety/depression
Takeaway: Effective coping often combines both strategies, depending on the situation.
How Do Psychologists Identify a Psychological Disorder?
Not every weird or upsetting behavior counts as a disorder — psychologists look at a few main criteria to make the call.
Criteria to Identify a Disorder/ The 3 Ds
Dysfunction: Interferes with daily life (e.g., work, hygiene, school)
Distress: Causes emotional suffering (to the person or others around them)
Deviance: Behavior goes against social/cultural norms
Important:
No one factor is enough by itself. It’s about the whole picture.
Mental health lies on a spectrum. Not black-and-white.
2. Why Diagnosing Matters (and Sometimes Backfires) 🌟
Classifying a disorder can trigger treatment and support — but it can also lead to misunderstanding and bias.
Positives of Diagnosis
Gives people clarity and a path toward treatment
Helps professionals design structured treatment plans
Opens up access to therapy, medication, and care
Reduces shame by showing it’s not personal weakness
Risks of Diagnosis
Stigma: Patients may feel labeled, embarrassed, or judged
Discrimination: Stereotypes can lead to unfair treatment (race, gender, age, etc.)
Cultural Variation: Some cultures view mental health differently, which can affect understanding or acceptance
Possible social limits (impacting jobs, school, relationships, etc.)
3. How Are Disorders Diagnosed? 🧰
Diagnosis isn’t done casually — it requires expert tools and trained mental health professionals.
Major Diagnostic Tools
DSM: Diagnostic and Statistical Manual of Mental Disorders
Made by the APA (American Psychiatric Association)
Used mainly in the U.S.
Regularly updated (currently DSM-5)
ICD: International Classification of Diseases
Created by the WHO (World Health Organization)
Used around the world
Also updated over time
These systems help keep diagnoses consistent, evidence-based, and more universally understood.
4. Different Perspectives on the Causes of Mental Disorders 🔍
There’s no single explanation for why people develop mental disorders — each psychological perspective offers a different lens on mental illness.
Eclectic Approach
Most psychologists use a mix of approaches to match each client’s needs
Major Psychological Perspectives
Behavioral Perspective
Mental illness = learned behavior
Result of conditioning (classical or operant)
Focuses on changing behavior through retraining
Cognitive Perspective
Cause = faulty or negative thinking
Cognitive distortions can lead to anxiety or depression
Treatment focuses on restructuring thought patterns
Psychodynamic Perspective
Focuses on the unconscious mind
Disorders linked to childhood and unresolved conflicts
Therapy aims to make the unconscious conscious
Humanistic Perspective
Mental health struggles tied to blocked personal growth or unmet needs
Support, purpose, and personal fulfillment are central
Biological Perspective
Cause = genetic or physiological issues
Mental illness is treated with medication or physical interventions
Evolutionary Perspective
Traits that helped our ancestors now may create problems
Example: Anxiety used to help us survive, now causes stress
Sociocultural Perspective
Mental health is shaped by one’s environment, culture, and relationships
Poverty, discrimination, and cultural norms play a role
5. Interaction Models: Where Everything Comes Together 🔄
Disorders usually aren’t caused by just one factor. These models explain how multiple influences combine.
Biopsychosocial Model
Biological: Genetics, brain structure, physical health
Psychological: Thoughts, emotions, behavior patterns, coping skills
Social: Environment, family, culture, community
This is the most widely accepted approach today.

Diathesis-Stress Model

Diathesis: Genetic predisposition to a disorder
Stress: Life events or environmental triggers
Together, they can lead to the development of a mental disorder
Example: You may inherit depression risk, but it doesn’t surface unless triggered by trauma or stress
What is Personality?
Our characteristic pattern of thinking, feeling, and acting is personality.
Sigmund Freud’s psychoanalytic theory proposed that childhood sexuality and unconscious motivations influence personality.
The humanistic theories focused on our inner abilities for growth and self-fulfillment.
Trait theories examine characteristics of behavior.
Social-cognitive theories explore the interaction between people’s traits and social context.
Psychodynamic Theories
The psychodynamic theories are theories that view personality with a focus on the unconscious and importance of childhood experiences.
Interaction between the conscious and unconscious mind.
These theories are derived from freud’s psychoanalysis- his theory of personality and the associated treatment methods.
