Development is best described as:

• A. A continuous quantitative increase
• B. The qualitative change seen as an individual acquires new skills
• C. Brain development in the early years
• D. Passive influence by the environment

Answer: (B)

Development is best described as qualitative changes in a person’s abilities as they acquire new skills and integrate them into functioning. This means development reflects changes in how a person thinks, moves, and interacts, not just an increase in size or amount. It spans physical, cognitive, social, and emotional domains and follows an orderly pattern across the lifespan. The idea that development is only brain growth in early years is too narrow, and describing environment as a passive influence misses the dynamic, reciprocal way people interact with their surroundings as they learn. For example, learning to speak or solve problems shows a change in functioning, not merely growth in height or weight.
