Physical development

Development continues across life and varies across people. Average patterns do not establish a universal timetable or a judgment about an individual's worth.

Maturation and Prenatal development

Objective: Explain maturation and prenatal development, distinguish their meanings, and apply them to a described case.

Maturation: Maturation is developmental change associated with biological processes and their interactions with experience. Prenatal development: Prenatal development occurs before birth and is affected by biological and environmental conditions. Development reflects interacting biological, social, and experiential processes across life. Average trajectories do not establish a rigid timetable or determine an individual's worth. Stage theories are explanatory models with limitations and competing interpretations. Assessments depend on tasks and context. A short vignette cannot establish an attachment pattern or future trajectory; responsible explanations preserve variation and distinguish proposed mechanisms from supported observations. Application: A child develops physical capacities over time. This most directly illustrates maturation. A lesson examines development during gestation. This most directly illustrates prenatal development.

Try itOriginal teaching scenario: A child develops physical capacities over time. Which idea from this section does it most directly illustrate?Show answer

Step 1 — Read the observation: A child develops physical capacities over time. Step 2 — Recall the relevant idea: Maturation is developmental change associated with biological processes and their interactions with experience. Step 3 — Connect the observation to the idea: The scenario is an illustration of maturation. Step 4 — Check the limit: This short scenario illustrates the concept; it does not establish every detail or exclude every other influence in a real situation.

Motor development and Puberty

Objective: Explain motor development and puberty, distinguish their meanings, and apply them to a described case.

Motor development: Motor development changes movement abilities through interacting growth and experience. Puberty: Puberty includes biological changes associated with sexual maturation, with variable timing. Development reflects interacting biological, social, and experiential processes across life. Average trajectories do not establish a rigid timetable or determine an individual's worth. Stage theories are explanatory models with limitations and competing interpretations. Assessments depend on tasks and context. A short vignette cannot establish an attachment pattern or future trajectory; responsible explanations preserve variation and distinguish proposed mechanisms from supported observations. Application: A child gains coordination through practice and physical change. This most directly illustrates motor development. Adolescents experience changes at different ages. This most directly illustrates puberty.

Aging and Developmental variability

Objective: Explain aging and developmental variability, distinguish their meanings, and apply them to a described case.

Aging: Aging includes diverse biological changes with substantial individual and contextual variation. Developmental variability: Variability means developmental timing and trajectories are not identical across individuals. Development reflects interacting biological, social, and experiential processes across life. Average trajectories do not establish a rigid timetable or determine an individual's worth. Stage theories are explanatory models with limitations and competing interpretations. Assessments depend on tasks and context. A short vignette cannot establish an attachment pattern or future trajectory; responsible explanations preserve variation and distinguish proposed mechanisms from supported observations. Application: Older adults differ in health and physical functioning. This most directly illustrates aging. A class avoids interpreting an average as a strict deadline. This most directly illustrates developmental variability.
