Developing Through the Life Span
Nature and nurture
How is our development influenced by the interaction between our genetic inheritance and experiences?
Infancy and Childhood: Motor Development
Continuity and stages
What parts of development are gradual and continuous and what parts change abruptly?
Stability and change
Which of our traits persist and which change through life?
Developmental Psychology’s Major Issues
Prenatal Development
Zygote: The life cycle begins at conception, when one sperm cell unites with an egg to form a zygote (fertilized egg). The zygote enters a 2-week period of rapid cell division.
Embryo: The zygote’s inner cells become the embryo; the outer cells become the placenta. The embryo is the developing human organism from about 2 weeks after fertilization through 2 months
Fetus: In the next 6 weeks, body organs begin to form and function. By 9 weeks, the fetus is recognizably human.
Prenatal development is not risk free.
Teratogen: An agent, such as a chemical or virus, that can reach the embryo or fetus during prenatal development and cause harm.
Fetal alcohol syndrome (FAS): Physical and mental abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, signs include a small, out-of-proportion head and abnormal facial features.
Motor skills
Develop as nervous system and muscles mature
Are primarily universal in sequence, but not in timing
Are guided by genes and influenced by environment
Involve the same sequence throughout the world
Piaget’s Theory and Current Thinking
Sensorimotor stage (birth to nearly 2 years)
Tools for thinking and reasoning change with development
Adaptation
Assimilation
Accommodation
