What is a developmental theory? • A public pronouncement indicating what a scientist believes about his or her area specific area of investigation What are the characteristics of a good theory? • Parsimony • Concise, yet able to explain a wide range of phenomena • Falsifiability • Capable of making explicit predictions • Heuristic value • Can be applied to unknown Question and controversies about human development • Assumptions about human nature • Innate purity versus original sin • Tabula rasa • Nature versus nurture • Activity versus passivity • Continuity of development • Stages of development • Quantitative versus qualitative change • Quantitative – changes in degree • Qualitative – changes in kind • Connectedness of development • Similarity versus differences Continuous versus Discontinuous Development Mature Immature Developmental Attribute Continuous Development Infant Adult AGE Continuous versus Discontinuous Development Mature Immature Developmental Attribute Discontinuous Development Infant Adult AGE Question and controversies about human development • Assumptions about human nature • Innate purity versus original sin • Tabula rasa • Nature versus nurture • Activity versus passivity • Continuity of development • Stages of development • Quantitative versus qualitative change • Quantitative – changes in degree • Qualitative – changes in kind • Connectedness of development • Similarity versus differences Theories of child development Psychoanalytic viewpoint Basic instincts • Eros – the life instinct • Thanatos – the death instinct Components of the personality • The Id – legislator of the personality • The Ego – executive of the personality • The Superego – judicial branch of the personality The theory of psychosexual development • The oral stage (birth – 1 year) • The anal stage (1 – 3 years) • The phallic stage (3 – 6 years) • The Oedipus complex • Latency period (6 – 12 years) • The genital stage (12 years on) Evaluation of theory Theories of child development Learning theory (Behaviorism) What is learning? • Classical conditioning • Operant conditioning • Reinforcers • Punishment • Observational learning Theories of social learning Evaluation of theory Theories of child development Cognitive developmental theory & Ecological theory Cognitive developmental theory • Children as constructivists • Organismic theorist Ethological theory • Study of the biological bases of behavior • Includes evolution, causation and behavior • Children are born with innate responses to evolution • Prefer naturalistic observations • Notion of a critical period Theories of child development Ecological theory The importance of the natural environment • Developmental psychology had become “… the science of the strange behavior children in strange situations with strange adults for the briefest possible periods of time.” • The importance of studying children in their natural environments • Environmental influences and behavior settings Ecological theory Environmental Layers
