Motivation Psychology

What drives behavior: understanding needs, goals, and the forces that move us to action.

What Is Motivation?

Motivation is the process that:

• Initiates behavior
• Directs behavior toward goals
• Sustains behavior over time
• Determines intensity of effort

Theories of Motivation

Maslow's Hierarchy of Needs

              /\
             /  \
            / Self-
           / Actual-
          /  ization
         /------------\
        /   Esteem     \
       /----------------\
      /  Love/Belonging  \
     /--------------------\
    /      Safety          \
   /------------------------\
  /     Physiological        \
 /----------------------------\

Critique: Maslow's hierarchy has weak empirical support as a strict ranking. Needs are often pursued simultaneously, and cultural variation is substantial. Treat the pyramid as a rough illustration, not a proven model.

Self-Determination Theory

Three basic psychological needs:

Types of motivation:

Key insight: More autonomous motivation → better performance, wellbeing, persistence.

Expectancy Theory

Motivation = Expectancy × Instrumentality × Valence

Practical: Motivation is low if any component is low.

Goal-Setting Theory

Effective goals are SMART:

• Specific
• Measurable
• Achievable
• Relevant
• Time-bound

Research findings:

• Specific, difficult goals outperform "do your best"
• Commitment matters
• Feedback is essential
• Self-efficacy predicts success

Intrinsic vs. Extrinsic Motivation

The Overjustification Effect

Adding extrinsic reward for intrinsically motivated behavior can undermine intrinsic motivation.

Classic study: Children who loved drawing were paid to draw → later drew less when not paid.

When rewards harm:

• Activity was already intrinsically interesting
• Rewards are expected
• Rewards are tangible
• Rewards are contingent on task completion

When rewards help:

• Activity is not interesting
• Rewards are unexpected
• Rewards are verbal (praise)
• Rewards signal competence

Fostering Intrinsic Motivation

• Provide autonomy (choice)
• Build competence (optimal challenge)
• Support relatedness (connection)
• Minimize controlling language
• Focus on purpose and meaning
• Give informational (not controlling) feedback

Drive and Arousal

Drive Reduction Theory

Biological needs create drives → behavior reduces drives → homeostasis restored.

Examples:

• Hunger → eating → satiation
• Thirst → drinking → hydration
• Fatigue → sleeping → restoration

Limitation: Doesn't explain curiosity, thrill-seeking, or behavior beyond survival.

Arousal Theory

Yerkes-Dodson Law: Performance peaks at moderate arousal.

Performance
    ^
    |      /\
    |     /  \
    |    /    \
    |   /      \
    |  /        \
    +-+----------+--> Arousal
   Low  Optimal  High

Optimal arousal varies by:

• Task complexity (simpler = higher optimal)
• Individual differences (sensation-seekers need more)
• Expertise (experts handle higher arousal)

Sensation Seeking

Some people need more stimulation:

• Thrill and adventure seeking
• Experience seeking
• Disinhibition
• Boredom susceptibility

Partly genetic, correlates with dopamine system.

Achievement Motivation

Need for Achievement

Fixed vs. Growth Mindset

Carol Dweck's research:

Practical: Praise effort and strategy, not innate ability.

Self-Efficacy

Belief in your ability to succeed in specific situations.

Sources:

1. Mastery experiences (most powerful)
2. Vicarious experiences (seeing similar others succeed)
3. Verbal persuasion (encouragement)
4. Physiological states (interpreting arousal positively)

Effects of high self-efficacy:

• Choose harder goals
• Greater effort
• More persistence
• Better stress management

Biological Motivations

Hunger

Biological factors:

• Blood glucose levels
• Hormones (ghrelin, leptin, insulin)
• Hypothalamus
• Set point theory

Psychological factors:

• Learned preferences
• Cultural influences
• Emotional eating
• Environmental cues

Sleep

Why we need sleep:

• Physical restoration
• Memory consolidation
• Emotional regulation
• Immune function

Sleep deprivation effects:

• Impaired cognition
• Emotional dysregulation
• Weakened immunity
• Weight gain
• Reduced motivation

Sex

Biological factors:

• Hormones (testosterone, estrogen)
• Limbic system
• Evolutionary pressures

Psychological factors:

• Attachment and intimacy needs
• Self-esteem
• Relationship quality
• Cultural/moral frameworks

Social Motivations

Need for Affiliation

Drive to form and maintain relationships.

Expressed through:

• Seeking social contact
• Fear of rejection
• Conforming to group norms
• Cooperation

Need for Power

Drive to influence or control others.

Two types:

• Personal power: Control for own benefit
• Socialized power: Influence for others' benefit

Need for Achievement

Drive to excel and succeed.

Expressed through:

• Setting challenging goals
• Seeking feedback
• Taking calculated risks
• Persistent effort

Motivation Killers

What Undermines Motivation

Procrastination

Not a time management problem. An emotion management problem.

Causes:

• Task aversion (boring, difficult)
• Fear of failure
• Perfectionism
• Decision fatigue
• Low self-efficacy
• Temporal discounting (present over future)

Solutions:

• Break into small steps
• Start with 2 minutes
• Manage emotions, not time
• Remove distractions
• Implementation intentions

Practical Applications

Motivating Yourself

1. Connect to values - Why does this matter?
2. Ensure autonomy - Find choices within constraints
3. Build competence - Start small, experience success
4. Create relatedness - Work with others, find accountability
5. Set clear goals - Specific, challenging, meaningful
6. Track progress - Visible feedback
7. Manage environment - Reduce friction for good behaviors
8. Address emotions - Process what's blocking you

Motivating Others

1. Explain purpose - The why behind the what
2. Provide autonomy - How, when, where flexibility
3. Build competence - Training, challenge, feedback
4. Foster belonging - Team connection
5. Recognize contribution - Specific, sincere appreciation
6. Set clear expectations - Goals and standards
7. Remove obstacles - What's in the way?
8. Model motivation - Show your own engagement

Sustaining Motivation

• Build habits (reduce motivation required)
• Create environment for success
• Find intrinsic reasons
• Celebrate progress
• Connect with supportive people
• Refresh purpose regularly
• Rest and recover (motivation depletes)
