Which one of the following is an incorrect statement ?

Answer: The incorrect statement is: "Maturation is synonym to growth".

Definitions and key distinctions:

• Growth: Quantitative increases in size, weight, or number of cells (measurable changes).

• Maturation: Qualitative development toward mature function (functional and structural refinement), not just increase in size.

• Development: Broad term covering progressive changes in structure and function (includes growth, maturation, cognitive and psychosocial changes).

Why the highlighted statement is incorrect:

• Growth is about measurable, numerical change; maturation is about attainment of mature function and quality of development. They are related but not synonymous.

• An individual can show maturation of function (e.g., neural control) without a simultaneous large quantitative increase, so the terms are conceptually distinct.

Clarification of the other statements:

• Development refers to physiological maturation: Partly true — physiological maturation is a component of development, but development also includes cognitive, emotional, and social change.

• Growth causes quantitative changes: Correct — growth is primarily about measurable increases.

• Development and maturation are process and product of growth: Acceptable with nuance — development is best seen as the process of change, while maturation can be considered one outcome or stage resulting from growth and developmental processes.

Conclusion: The statement equating maturation with growth is incorrect because it ignores the qualitative difference between maturation and quantitative growth.
