Theories of Human Development

1: Introduction—The Value of Theories
This lecture introduces the major objectives of the course. It allows students to assess where they stand on major issues regarding human development. The lecture then discusses the value of scientific theories for understanding development, and the criteria for judging whether a theory is valuable.

2: The Early History of Child Study
Prior to and during the Industrial Revolution in Europe and America, people often showed a lack of humane concern for children. This translated into an absence of systematic study of child development. Concern for, and evaluation of, children resulted in part from the influence of a few physicians and religious leaders.

3: Two Worldviews—Locke vs. Rousseau
Two major philosophers, both concerned with humane child rearing and education, changed the prevailing perception of children. John Locke espoused the "mechanistic" worldview: children are neutral ("blank slates") and function like machines. Jean-Jacques Rousseau proposed the "organismic" worldview: children are good, and function like organisms.





8: Erikson's Psycho-Social Theory
We first discuss neo-Freudian revisions in Freud's theory. We then discuss Erikson's history, including his experience with his own identity crisis, and describe how his stages of development are based on the need to develop mastery and personal identity through a series of crises in one's life cycle.


10: Identity and Intimacy
Erikson was the first to propose two pivotal stages of development after childhood. During adolescence, Stage 5 is a crisis of developing identity versus role confusion. Stage 6, in young adulthood, is a crisis of developing intimacy versus isolation. The lecture concludes with differences between women and men in developing identity and intimacy.

11: Erikson's Later Stages—Adult Development
Erikson's last two stages occur in adulthood and old age. Stage 7 is a crisis of developing generativity versus stagnation, and Stage 8 is a crisis of developing ego integrity versus despair. The last stage connects all the issues with which a person has already dealt.


13: How Nature Ensures That Attachment Will Occur
Bowlby rejected Freudian psychodynamic theory as inadequate to explain attachment. He turned instead to ethology theory, and its concept of innate releasing mechanisms. We discuss the allure of babyish features and their role in attachment, and attachment in the first year of life.

14: Development of Secure and Insecure Attachments
This lecture describes the normal development of a secure attachment, and Ainsworth's "strange situation" task—the most popular assessment for secure attachment. We examine insecure attachments: what they are, how they may predict several psychopathological problems in development, and causes.

15: Early Attachments and Adult Relationships
Our discussion concludes with relations between early attachment and later relationships. Bowlby developed the "internal working model" of a child's attachment, which provides constant security, and influences subsequent attachments. Early attachments influence adult romantic relationships.

16: Bandura's Social Learning Theory
A fourth major theory, Albert Bandura's social learning theory, added a cognitive focus to learning theory. It showed how the influence of what one expects to happen is more important than what does happen. This focus led to the concept of "vicarious reinforcement."


18: Piaget's Cognitive-Developmental Theory
This lecture introduces the most important theorist in the field of child development, Jean Piaget. It describes Piaget's history and his attempt to combine naturalist biology and philosophy to create a field called genetic epistemology (how we come to know what we know).




22: Vygotsky's Cognitive-Mediation Theory
Lev Vygotsky was practically unknown to Western thinkers until recently, but his theoretical influence on development and education is constantly increasing. As a Russian theorist he believed that Marxism could provide a foundation for a better theory of psychological development.


24: Conclusion—Our Nature and Development
This concluding lecture uses the allegory of blind men describing an elephant to illustrate how different theories might give a partial or even false understanding of human nature and development. We discuss ways to integrate the major theories, using the example of gender role development. We end with a reprise: Where does the student now stand regarding major issues of human development?
