The change in behaviour is commonly known as:

In psychology, learning is defined as a relatively permanent change in an organism's behaviour that occurs as a result of experience or practice. This distinguishes it from short-lived mental or emotional states — such as understanding a concept, thinking through a problem, or feeling an emotion — none of which are, by themselves, names for a change in behaviour.

Applying this definition to the phenomenon the question names — 'a change in behaviour' — only one of the four given terms describes a psychological process whose defining feature is exactly that: an alteration in behaviour.

• Understanding: the cognitive grasp of an idea's meaning — a mental state, not itself a name for a change in behaviour.

• Thinking: the ongoing process of reasoning or reflection — a mental activity, not itself a name for a change in behaviour.

• Learning: the standard psychological term for a lasting change in behaviour produced by experience or practice — it matches the phenomenon the question describes.

• Feeling: an emotional or affective response — it can influence behaviour momentarily but is not the technical name for a lasting change in behaviour.

Correct answer: Learning. This item matches Question 56 of the KVS PGT Computer Science exam (23 February 2023, evening shift); the exam's official provisional answer key confirms Learning as correct.

The question's wording does not spell out 'due to experience', but among the four given options only Learning names a phenomenon of behavioural change; the other three name cognitive or emotional states rather than a term for behaviour change, so the intended answer is not genuinely ambiguous.
