Q.Explain the concept of motivation.

Motivation is the psychological concept used to explain what 'moves' or activates behaviour — the word itself comes from the Latin 'movere', meaning movement. In everyday life, we routinely explain our own and others' actions in terms of motives: a person attends college because they want to learn, need a qualification for a good job, or wish to make their family proud, and usually some mixture of such reasons together explains a given choice. What makes the concept of motivation useful to psychologists is that motives are general states that hold across many different situations, which means they let us make predictions about behaviour — someone with a strong need for achievement, for example, is likely to work hard whether the setting is school, sport, business or music. Motivation is therefore treated as one of the central determinants of behaviour, and it acts as a broad umbrella term covering several related concepts: instincts, drives, needs, goals, and incentives.

A need is defined as a lack or deficit of some necessity — something the body or the person requires but currently does not have enough of. A need produces a drive, which is a state of tension or physiological arousal; this drive energises activity, and initially the resulting behaviour is fairly undirected or random. As soon as one of these activities happens to lead toward a goal that satisfies the original need, it becomes goal-directed behaviour, and achieving that goal reduces the drive, allowing the organism to return to a balanced, low-arousal state. This sequence — need, drive, arousal, goal-directed behaviour, achievement, and reduction of arousal — is what psychologists call the motivational cycle, and it repeats continuously across a person's life as new needs keep arising.

It is worth noting that motivation is not a single, uniform process — psychologists distinguish between motives that are biological in origin (like hunger, thirst and sex, arising from the body's own physiological mechanisms) and motives that are psychosocial in origin (like the needs for achievement, affiliation and power, learned mainly through a person's interactions with their social world). In practice, these two broad types of motives are deeply interdependent rather than operating in isolation from one another, and understanding motivation properly requires appreciating both where a motive originates and how the underlying motivational cycle plays out once that motive is aroused.
