11.1.1 Motivation: instincts, needs, drives, motives and theories
Motivation (Latin movere, "to move") is the inner process that starts, directs and keeps up behaviour towards a goal: a need creates a drive, the drive pushes goal-directed behaviour, and reaching the incentive reduces the need. Motives are biological (hunger, thirst, sex) or psychosocial (achievement, affiliation, power, curiosity), and they are explained by instinct, drive-reduction, arousal, incentive and humanistic (Maslow) theories. Maslow's five levels, intrinsic vs extrinsic motivation, McClelland's training work and level of aspiration are set out for teachers in EDU-LR-05; this note adds the psychology-paper detail.

Core facts
- Motive: a state that energises, activates and directs behaviour towards a goal. Motives are inferred from behaviour, not seen directly.
- Motivation cycle (NCERT): Need → Drive → Goal-directed (instrumental) behaviour → Goal / incentive reached → Relief (need reduced).
- Need: a lack or deprivation (shortage of water in the body).
- Drive: the state of tension or arousal the need produces (thirst); it pushes.
- Incentive: the goal object that satisfies the need (water); it pulls.
- Homeostasis: the body's tendency to keep its internal state steady (temperature, blood sugar, water). Term coined by Walter B. Cannon (1926) and made known by his book The Wisdom of the Body (1932). Upsetting it creates a drive.
- Instinct: an innate, unlearned, fixed pattern of behaviour found in all members of a species (a bird building its nest).
- William McDougall (An Introduction to Social Psychology, 1908): behaviour is driven by instincts, each with its own emotion (flight → fear, pugnacity → anger, curiosity → wonder, parental instinct → tender emotion).
- Sigmund Freud: two groups of instincts: life instincts (Eros), whose energy is the libido, and death instincts (Thanatos), the source of aggression. Both energise the id.
- Modern ethologists (Konrad Lorenz, Niko Tinbergen) speak of fixed action patterns instead.
- Two broad kinds of motives:
- Biological (primary, physiological, innate): hunger, thirst, sex, sleep, avoiding pain, need for oxygen and temperature, maternal drive.
- Psychosocial (secondary, social, learned / acquired): shaped by social interaction and culture. NCERT lists affiliation, power, achievement, curiosity and exploration.
- The two kinds interact: they are not independent (social pressure changes what and when we eat; hunger lowers interest in social goals).
- Hunger: signals from the stomach (contractions; Cannon and Washburn, 1912, swallowed balloon), blood glucose, hormones (ghrelin raises hunger, leptin from fat cells lowers it) and the hypothalamus:
- Lateral hypothalamus (LH): "hunger / feeding centre"; damage → animal stops eating.
- Ventromedial hypothalamus (VMH): "satiety centre"; damage → overeating and obesity.
- Thirst: dry mouth, loss of water from body cells (osmotic thirst, sensed by osmoreceptors in the hypothalamus) and loss of blood volume (hypovolemic thirst, sensed by the kidneys and blood-pressure receptors).
- Sex drive: hormones (testosterone, oestrogen) plus learning and culture; unlike hunger and thirst, it is not needed for the individual's survival.
- Strength of drives in rats (Columbia obstruction box, C.J. Warden, 1931): the number of times a rat crossed an electrified grid to reach a goal ranked maternal > thirst > hunger > sex > exploration.
- Psychosocial motives:
- Need for achievement (n-Ach): to meet a standard of excellence; measured by the TAT (Murray); studied by McClelland and Atkinson.
- Need for affiliation (n-Aff): to seek and keep relationships with others; rises under threat or anxiety (Schachter, 1959: frightened people preferred to wait with others).
- Need for power (n-Pow): to have impact, control or influence on others' behaviour and feelings, to charm or impress them.
- Curiosity and exploration: to seek new information and experience for its own sake (pleasure); seen in monkeys who work to open a window just to look out.
- Theories at a glance:
| Theory | Key name | Main idea | Push or pull |
|---|---|---|---|
| Instinct | McDougall (1908) | innate patterns drive behaviour | push from inside |
| Drive-reduction | Clark Hull (1943) | needs create drives; behaviour reduces them | push |
| Arousal (optimal level) | Yerkes and Dodson (1908); Hebb | we seek a moderate level of arousal | both |
| Incentive | Bolles and others (1960s–70s) | external goals attract behaviour | pull |
| Hierarchy of needs | Abraham Maslow (1943, 1954) | lower needs first, then growth to self-actualisation | humanistic |
| Three (acquired) needs | David McClelland (1961) | achievement, affiliation, power are learned | learned |
- Maslow's hierarchy (detail in EDU-LR-05): physiological → safety → love and belongingness → esteem → self-actualisation. Self-actualisation = becoming all one is capable of becoming.
- Intrinsic motivation: the activity is rewarding in itself (curiosity, interest). Extrinsic motivation: done for an outside reward or to avoid punishment (marks, money, praise). Detail in EDU-LR-05.
Explained
1. Need, drive and incentive in one example. A probation officer skips lunch on a long field day. By evening his body lacks glucose (need); he feels hungry and restless (drive); he walks to a hotel and orders food (goal-directed behaviour); the meal (incentive) restores the balance (relief), and the cycle ends until the next need arises. A smell of biryani on the way can start eating even before strong hunger: that is the pull of an incentive.
2. Instinct theory and why it faded
- It explained behaviour by naming an instinct for it: people fight because of a "pugnacity instinct". This is circular: the behaviour is the only evidence for the instinct that is said to cause it.
- Lists grew without limit; later writers counted thousands of "instincts" in the literature.
- Human behaviour varies too much across people and cultures to be fixed and unlearned.
- What remains: the idea that some behaviour patterns are inborn (ethology) and Freud's life and death instincts in personality theory.
3. Drive-reduction theory (Clark Hull)
- A biological need creates an unpleasant state of tension, the drive; the organism is pushed to reduce (not increase) that tension and return to homeostasis. Behaviour that reduces a drive is reinforced and learnt.
- Primary drives come from bodily needs (hunger, thirst); secondary (acquired) drives are learnt through association with primary ones (the wish for money, which buys food).
- Explains well: drinking when thirsty, eating when hungry, sleeping when tired.
- Cannot explain: behaviour that raises tension or arousal: rock climbing, bungee jumping, watching horror films, solving puzzles for fun, curiosity; eating dessert when already full; a starving hunger striker.
4. Arousal theory (optimal level)
- Each person tries to keep an optimal (moderate) level of arousal. When arousal is too low we seek stimulation (switch on music, go out); when too high we seek calm.
- Yerkes–Dodson law (1908): performance is best at moderate arousal and falls at very low or very high arousal (an inverted U). For difficult tasks the best level is lower; for easy tasks it is higher.
- Sensory deprivation (Bexton, Heron and Scott, McGill University, 1954): paid students lying in a bare cubicle with goggles and gloves could not stay more than two or three days; they became bored, restless and had trouble thinking. People need stimulation, not just drive reduction.
- Sensation seeking (Marvin Zuckerman): people differ in how much novelty and risk they need; high sensation seekers choose adventure sports and fast driving.
5. Incentive theory
- Behaviour is pulled by the expected value of external goals, not only pushed by inner drives. Positive incentives attract (prize, praise, tasty food); negative incentives repel (fine, punishment).
- It explains eating when not hungry and working for money or recognition.
- Limit: used alone it ignores internal states; today drive and incentive are seen as working together (push and pull).
6. Comparing the theories
| Behaviour | Best explained by | Why |
|---|---|---|
| Drinking water when thirsty | drive-reduction | a bodily need is met, tension falls |
| Rock climbing for adventure | arousal / sensation seeking | arousal is raised on purpose |
| Eating sweets after a full meal | incentive | the goal pulls; no hunger push |
| Writing a poem for its own joy | Maslow / intrinsic | growth need, no outside reward |
7. Psychosocial motives compared
| Motive | Aim | Typical behaviour | Shown by |
|---|---|---|---|
| Achievement | standard of excellence | prefers moderate risk, wants feedback | entrepreneur, topper |
| Affiliation | warm relationships | joins groups, seeks approval | team member, friend |
| Power | impact and control over others | seeks status, leadership, charms others | politician, manager |
| Curiosity / exploration | new information and experience | asks, explores, enjoys novelty | scientist, traveller |
8. Maslow's self-actualised people. Maslow studied the lives of people he judged to have used their full potential (Abraham Lincoln, Albert Einstein, Eleanor Roosevelt and others). Their common features:
- Accurate perception of reality and comfort with uncertainty; open to new experience and challenge.
- Acceptance of self, others and nature; spontaneous and natural.
- Problem-centred: devoted to a task or mission outside themselves.
- Need for privacy and independence (autonomy): they can be alone without feeling lonely, but they are not socially withdrawn.
- Deep, close relationships with a few people, and social interest (a feeling of kinship with all humanity); democratic attitude.
- A philosophical, unhostile sense of humour (they do not laugh at others' pain).
- Fresh appreciation of ordinary things, creativity, and frequent peak experiences (moments of intense joy and wonder).
- Strong ethical sense; resistance to blind conformity.
9. McClelland's three needs (acquired needs theory). Needs for achievement, affiliation and power are learnt in childhood and culture, and each person has a different mix. High n-Ach people make good entrepreneurs; good managers of large organisations tend to have high n-Pow (used for the group), lower n-Aff. McClelland measured needs through stories written to TAT pictures (The Achieving Society, 1961).
Common traps
- ✗ "Drive-reduction theory says the organism tries to increase the tension created by needs." ✓ It tries to reduce the tension and return to homeostasis.
- ✗ "Drive-reduction explains rock climbing and horror films." ✓ These raise arousal; arousal / sensation-seeking theory explains them. Drive-reduction fits eating when hungry, drinking when thirsty.
- ✗ "Biological and psychosocial motives are independent of each other." ✓ The two kinds exist, but they interact and influence each other.
- ✗ "Curiosity is a biological motive." ✓ NCERT lists curiosity and exploration among psychosocial motives, with affiliation, power and achievement. (The 2023 key treated "belongingness", a Maslow level, as not one of these psychosocial motives.)
- ✗ "Need for power = need for relationship." ✓ Power = influence, control, charming others; affiliation = relationships; achievement = standard of excellence; exploration = pleasure of new experience.
- ✗ "Self-actualised people are socially withdrawn." ✓ They value privacy but have deep relationships, social interest, humour and openness to novelty and challenge.
- ✗ "The lateral hypothalamus is the satiety centre." ✓ LH = hunger (feeding); VMH = satiety. VMH damage → overeating.
- ✗ "Instinct theory: Clark Hull." ✓ Instincts: McDougall (and Freud's Eros / Thanatos); drive-reduction: Hull.
- ✗ "Yerkes–Dodson: the harder the task, the more arousal helps." ✓ Difficult tasks need lower arousal; performance is best at moderate arousal.
- ✗ "Incentives push; drives pull." ✓ Drives push from inside; incentives pull from outside.
- ✗ "In the obstruction box, hunger was the strongest drive." ✓ Maternal drive was strongest, then thirst, hunger, sex.
Quick revision
- Motivation: movere; need → drive → goal-directed behaviour → incentive → relief.
- Homeostasis: Walter Cannon (1932); drive pushes, incentive pulls.
- Instincts: McDougall 1908 (instinct + emotion); Freud: Eros (libido) and Thanatos energise the id.
- Biological motives: hunger (LH hunger, VMH satiety, ghrelin up, leptin down), thirst (osmotic, hypovolemic), sex.
- Psychosocial motives: achievement, affiliation, power, curiosity and exploration.
- Drive-reduction: Hull 1943; fails for rock climbing, horror films, curiosity.
- Arousal: optimal level, Yerkes–Dodson inverted U; sensory deprivation (McGill 1954); Zuckerman sensation seeking.
- Incentive theory: external goals pull behaviour.
- Maslow's self-actualised: realistic, accepting, autonomous, private but not withdrawn, humour, peak experiences.
- McClelland: n-Ach, n-Aff, n-Pow learned; TAT; intrinsic > extrinsic for lasting effort.
Go deeper: Deeper (beyond what APPSC Paper I usually asks)
Deeper Advanced
1. Two meanings of "need". In Hull's theory a need is a bodily deficit; in Maslow's and Murray's use it also covers psychological needs (esteem, achievement). Henry Murray (Explorations in Personality, 1938) listed about twenty "psychogenic needs" (achievement, affiliation, dominance, autonomy, nurturance and others) and the environmental "press" that arouses them.
2. Maslow tested against evidence. Studies across cultures support the broad idea that basic needs matter first, but not the strict order: people starve for a cause, artists put creativity before safety, and collectivist cultures may rank belonging above esteem. Maslow himself said a need need not be fully met before the next one rises (a "relative" satisfaction). Later lists add cognitive and aesthetic needs and self-transcendence.
3. Intrinsic motivation and rewards. In Lepper, Greene and Nisbett's study (1973), children who were promised a certificate for drawing later drew less in free time than children who got no reward or an unexpected one: an expected outside reward can weaken inner interest (overjustification effect). Deci and Ryan's self-determination theory (1985) says intrinsic motivation grows when needs for autonomy, competence and relatedness are met.
4. Opponent-process theory (Richard Solomon, 1980): every strong emotional state is followed by its opposite (fear of a parachute jump → relief and joy). With repetition the first reaction weakens and the opposite grows, which helps explain thrill seeking and addiction.
5. Motivation and offenders. For a probation officer, motive theories give a vocabulary for case work: an unmet basic need (hunger, shelter) can drive theft; a strong need for affiliation can pull a youth into a gang; a high need for power can show as bullying; low arousal and sensation seeking are linked with risk taking. Rehabilitation tries to meet basic needs and redirect motives to lawful goals.
