CHAPTER OUTLINE
I.
The nature of theories
A. The importance of theories
1. Lens for interpreting any number of facts and observations
2. Guides the collection of new information
B. Qualities of a good theory
1. Internally consistent-- its different parts are not contradictory
2. Falsifiable-- generates testable hypotheses
3. Supported by data-- describes, predicts, and explains human development
II.
Basic issues in human development
A. Assumptions about human nature
1. Hobbes-- society must control inherent selfishness and aggression
2. Rousseau-- society must not interfere with innate goodness
3. Locke-- child as tabula rasa “blank slate”
B. Nature and nurture
1. Nature-- genetic/biological predisposition
2. Nurture-- emphasis on experience
C. Activity and passivity
1. Activity-- control over one’s development
2. Nurture-- product of forces beyond one’s control
D. Continuity and discontinuity
1. Continuity -- gradual change
2. Discontinuity-- abrupt change
3. Qualitative or quantitative change
4. Developmental stages part of discontinuity approach
E. Universality and context-specificity
1. Universality-- developmental change common to everyone
2. Nurture-- developmental changes vary by individual/culture
III.
Freud: Psychoanalytic theory
A. Instincts and unconscious motives
1. Instincts-- inborn biological forces that motivate behavior
a. Life instincts-- life-sustaining activities
b. Death instincts-- destructive forces
2. Unconscious motivation-- influences beyond our awareness/control

a. all psychic energy contained here
b. basic biological urges
c. impulsive
d. pleasure principle (seeks immediate gratification)
2. Ego
a. rational side of personality
9
Chapter 2
b. reality principle (realistic way of gratifying instincts)
c. balances between id and superego
3. Superego
a. internalized moral standards
b. perfection principle (adhere to moral standards)
4. Id, ego and superego conflict common/inevitable
5. Problems arise when level of psychic energy unevenly distributed
C. Psychosexual development
1. Importance of libido-- sex instinct’s energy shifts body locations
2. Conflict of id and social demands leads to ego’s defense mechanisms
a. fixation-- Development arrested at early stage
b. regression-- Retreat to earlier stage
3. Five stages of psychosexual development
a. oral stage

2. Erikson is most important life span neo-Freudian theorist
3. Erikson’s differences with Freud
a. Less emphasis on sexual and more on social influences
b. Less emphasis on id, more on rational ego
c. More positive view of human nature
d. More emphasis on developmental changes in adulthood
B. Psychosocial Development
1. Resolution of eight major psychosocial crises
2. Trust versus mistrust-- key is general responsiveness of caregiver
3. Autonomy versus shame-- terrible twos
4. Initiative versus guilt-- preschool sense of autonomy
5. Industry versus inferiority-- elementary age sense of mastery
6. Identity versus role confusion-- adolescence acquisition of identity
7. Intimacy versus isolation-- young adult commitment
8. Generativity versus stagnation-- middle age sense of having produced something
meaningful
9. Integrity versus despair-- elderly sense of life meaning and success

10. Personality strengths “ego virtues” developed during stages
11. Stage development due to biological maturation and environmental demands
C. Strengths and weaknesses
1. Its emphases on rational, adaptive nature and social influences easier to accept
2. Influenced thinking about adolescence and beyond
3. Like Freud, difficult to test
4. Provides description, but not adequate explanation of development
V.
Learning theories
A. Watson: Classical Conditioning
1. Behaviorism-- belief that only observed behavior should be studied
2. Worked with colleague Rosalie Rayner
a. Watson and Rayner classically condition infant “Albert” to fear rat
b. Loud noise was unconditioned (unlearned) stimulus
c. Crying (fear) was unconditioned (unlearned) response
d. White rat became conditioned (learned) stimulus – producing conditioned
response of crying—after it was paired with loud noise
3. Reject stage conceptualization of development
B. Skinner: Operant Conditioning
1. In operant conditioning learning thought to become more or less probable
depending on consequences
2. Reinforcement-- consequences that increase probability of future response
3. Punishment-- consequences that suppress future response
4. Positive-- something added
5. Negative-- something taken
a. positive reinforcement—something pleasant added in attempt to
strengthen behavior
b. negative reinforcement—something unpleasant taken in attempt to
strengthen behavior
c. positive punishment—something unpleasant added in attempt to
weaken behavior
d. negative punishment—something pleasant taken in attempt to
weaken behavior
6. Extinction-- no consequence given and behavior becomes less frequent
7. Skinner emphasized positive reinforcement
8. Physical punishment best used in specific circumstances like…
a. administered immediately following act
b. administered consistently following offense
c. not overly harsh
d. accompanied by explanation
e. administered by otherwise affectionate person
f. combined with efforts to reinforcement acceptable behaviors
C. Bandura: Social Learning Theory
1. Humans’ cognitive abilities distinguish them from animals-- can think about
11
Chapter 2
behavior and anticipate consequences
2. Observational learning most important mechanism for behavior change
3. Classic experiment using “Bobo” doll showed that children could learn from
model
4. Vicarious reinforcement-- learner changes behaviors based on consequences
observed being given to a model
5. Reciprocal determinism-- mutual influence of individuals and social
environments determines behavior
D. Strengths and weaknesses of learning theory
1. Learning theories are precise and testable
2. Principles operate across the life span
3. Practical applications
4. Doesn't show that learning actually causes observed developmental changes
5. Oversimplifies development by focusing on experience and downplaying
biological influences
VI.
Cognitive developmental theory
Jean Piaget Swiss scholar greatly influences study of intellectual development in children
1. Emphasizes errors in thinking
2. Argues that cognitive development is qualitative in nature
A. Piaget's Constructivism
1. Constructivism--active construction of knowledge
2. Stage progression due to interaction of biological maturation and environment
B. Stages of cognitive development
1. Sensorimotor stage
a. birth to age 2
b. deal with world directly through perceptions and actions
c. unable to use symbols
2. Preoperational stage
a. ages 2 to 7
b. capacity for symbolic thought
c. lack tools of logical thought
3. Concrete operations stage
a. ages 7 to 11
b. use trial-and-error strategy
c. perform mental operations in their heads
d. difficulty with abstract and hypothetical concepts
4. Formal operations stage
a. ages 11 and later
b. think abstractly and hypothetically
c. can devise “grand theories”
C. Strengths and weaknesses
1. Many of Piaget’s concepts accepted
2. Influential in education and child rearing practices
3. Too little emphasis on motivation and emotion
Chapter 2

4. Questioning of stage model
VII.
Contextual and Systems Theories
Changes over life span arise from ongoing transactions and mutual influences between
organism and changing world
Some theories arisen from psychobiology others focus on social context
A. Vygotsky: A Sociocultural Perspective
1. Russian psychologist who took issue with Piaget
2. Sociocultural perspective-- development shaped by organism growing in culture
3. Cognitive development is social process
4. Children co-construct knowledge
5. Paid too little attention to biology
B. Bronfenbrenner: The Bioecological Approach
1. Relationship between individual and environment is reciprocal
2. Bioecological approach-- emphasis on nature and nurture
3. Developing person embedded in interacting environmental systems
a. microsystem-- immediate environment
b. mesosystem-- interrelation ships between microsystems
c. exosystem-- influential social setting not directly experienced
d. macrosystem-- larger, subcultural or cultural contexts
4. Strengths and weaknesses
a. emphasizes some neglected concepts
i. Development occurs in context
ii. Environments are dynamic
b. not yet a full-blown theory--- and may never be
c. must develop theories for all subgroups (race, age)
VIII. Theories in Perspective
A. Stage Theorists: Freud, Erikson, Piaget
1. Development guided in universal direction
2. Humans need a supportive environment
3. Humans evolve through distinct stages
B. Learning Theorists: Watson, Skinner, Bandura
1. Developmental pathways depend on environment
2. Deliberate steps needed to shape development
C. Contextual and Systems Theorists: Vygotsky, Bronfenbrenner
1. Focus on dynamic relationship between person and environment
2. Humans are active in developmental process
3. Potential exists for qualitative and quantitative change
4. Developmental pathways depend on interplay of internal and external influences
D. Changing world views
1. Our understanding of human development is ever-changing
2. Contextual theory prevalent today
3. Less extreme positions
4. More emphasis on “minitheories”
