Question 1 · 1 mark · Difficulty 1/3

Which stage of human development is characterised by the most rapid rate of physical growth?

  1. A. Adolescence
  2. B. Early childhood
  3. C. Infancy
  4. D. Late childhood
Show answer & explanation
✓ Answer: CC. Infancy
Infancy (birth to approximately 2 years) is the period of most rapid physical growth in the human life cycle. During this stage, body length and mass increase dramatically within a short time. Adolescence also shows rapid growth but is second to infancy in terms of rate.
Question 2 · 1 mark · Difficulty 2/3

A growth curve for a human being typically shows which pattern from birth to adulthood?

  1. A. Constant linear increase until adulthood
  2. B. Rapid growth in infancy, slower in childhood, rapid again in adolescence
  3. C. Slow growth in infancy, then steady increase throughout life
  4. D. Rapid growth throughout childhood with a sudden stop at puberty
Show answer & explanation
✓ Answer: BB. Rapid growth in infancy, slower in childhood, rapid again in adolescence
The human sigmoid (S-shaped) growth curve shows rapid growth in infancy, a slower and steadier increase during childhood, then a second rapid phase during the adolescent growth spurt. This two-peak pattern is a key characteristic of human growth. Students often confuse this with a simple linear or constant growth pattern.
