Growth and Development in Childhood and Adolescence: Principles, Stages and Adolescent Change
What the exam tests
This domain asks you to separate growth from development, apply the principles of development, map Piaget and Erikson stages, and explain adolescent change without labelling normal variation as disorder.
Core rules
- Growth is quantitative and measurable (height, weight, head circumference). Development is qualitative and progressive (walking, abstract reasoning, empathy).
- Principles: continuous, sequential, cephalocaudal (head before limbs), proximodistal (trunk before fingers), general-to-specific, and individual differences.
- Domains: physical, motor, cognitive, language, social, emotional.
- Piaget: sensorimotor (0–2), preoperational (2–7), concrete operational (7–11), formal operational (11+).
- Erikson's adolescent task is identity vs role confusion.
- WHO adolescence = 10–19 years. Puberty includes a growth spurt, secondary sexual characters, menarche in girls and spermarche in boys; timing varies widely.
Worked example
A 13-year-old girl has gained 8 cm in a year, has begun menstruation, and now argues that a rule is unfair because it treats people unequally. Identify growth, development and domain. Reasoning: the 8 cm gain is growth (quantitative); menarche is a pubertal milestone, not a score; the argument shows formal-operational and moral reasoning (cognitive development). The answer should not call her “early” or “late” without age norms because normal ranges are broad.
Traps
- Writing “growth and development” as synonyms.
- Reversing cephalocaudal and proximodistal.
- Treating menarche as the start of adolescence rather than a mid-puberty event.
- Forgetting that development continues through adolescence and adulthood.
