Human Growth and Development / Unit 1 HGD 0009 short lesson, about 20 seconds
Continuous and Discontinuous Change
Captions available
The idea
Continuous development is gradual, day-by-day progress; discontinuous development is a change in kind that does not follow directly from what came before.
In practice
Vocabulary growing word by word, then two-word phrases giving way, seemingly overnight, to sentences.
Where people slip
One change can show both patterns. Puberty looks sudden, yet the hormonal preparation behind it is continuous.
Your place on the trail
Every lesson rests on earlier ones and opens later ones. Tap any to jump.
