Which of the following is not a product of learning?

Maturation is natural biological growth that unfolds without practice or experience, so it is not a product of learning.

Attitudes are learned dispositions to respond, acquired through experience.

Concepts are learned mental categories formed by grouping objects and ideas.

Knowledge is information gained and organised through learning.

Learning needs experience or practice, whereas maturation depends only on the passage of time and physical development.

Reading readiness in a child, for instance, depends on maturation before learning can proceed.
