Document Summary
Child development: is the scientific study of processes of change and stability in human children. Developmental scientists study two kinds of change: quantitative and qualitative. Quantitative change: is a change in number or amount, such as in height, weight, size of vocabulary, or frequent of communication. Qualitative change: is a change in kind, structure, or organization. It is marked by the emergence of new phenomena that cannot be anticipated easily on the basis of earlier functioning. Basic research: kind undertaken purely in a spirit of intellectual inquiry. Applied research: addresses a practical problem, is less becoming less meaningful. Scientists separate the three domains: physical development, cognitive development, and psychosocial development. Physical development: growth of the body and brain, sensory capacities, motor skills, and health. Cognitive development: change and stability in mental abilities, such as learning, memory, language, thinking, moral reasoning, and creativity. They are closely related to physical and emotional growth.
