What does the principle of individual differences in growth and development…

Concept

Development follows broad, common patterns, but its timing, pace, and expression vary from one individual to another.

Heredity, environment, health, experience, and opportunity interact differently for each child, so children of the same age are not expected to progress identically.

Application

The statement that children develop at their own unique rates directly expresses individual variation in the pace and timing of development.

Contrast

• All children develop identically assumes uniform development and removes individual variation.

• Development happens only in childhood concerns the duration of development, not individual differences; development continues across the lifespan.

• Growth stops after puberty concerns physical growth and a proposed stopping point, not variation in developmental rates.

Cross-check

If individual differences are recognized, two children of the same chronological age may reach developmental milestones at different times while still following a normal broad sequence.

Therefore, the principle suggests that children develop at their own unique rates.
