Chapter 4: Emotions and Motivation
In 1872, an ageing Charles Darwin — already famous for his theory of evolution — published a quieter and stranger book. It was called The Expression of the Emotions in Man and Animals. In it, Darwin asked a simple question that most people had never thought to ask. Why does a frightened person, whether in London or in a remote village, open the eyes wide, freeze, and feel the heart race in almost exactly the same way?
Darwin gathered observations from missionaries and travellers across the world. He watched his own infant son grow. He studied animals, and photographs of people in distress. Everywhere he looked, he found the same patterns — the bared teeth of anger, the wide eyes of fear, the easy smile of joy. He concluded that our emotional expressions are not learned manners but inherited equipment, shaped over a very long time because they once helped our ancestors survive.
Darwin had touched on something important. Emotions are not just private feelings floating somewhere inside the mind. They are events of the whole body — the pounding heart, the flushed face, the trembling hands — and they push us to act. They make us run, fight, reach out, or hold on. That push to act has its own name in psychology: motivation. This chapter is about these two closely linked engines of human behaviour.

By the time you reach the end of this chapter, you will be able to answer each of the questions below for yourself.
4.1 Emotion: Meaning and Nature
4.1.1 What is Emotion?
You have felt your heart thud before an exam result is read out. You have felt warmth spread through you when a friend hugs you at the station. These stirred-up states of feeling are what we call emotions, and life without them would be flat and colourless.
The word emotion comes from the Latin word emovere, meaning “to move out” or “to stir up”. The word itself hints at the truth: an emotion is a state that moves us, both inside the body and towards some action.
An emotion is a complex feeling-state that involves the whole person. It stirs up changes in the body, it is felt consciously as pleasant or unpleasant, and it shows itself in behaviour.
Psychologists agree that every emotion is built from three components. Understanding these three parts makes the rest of this chapter much easier to follow.
The first component is physiological arousal — the bodily changes that accompany an emotion. When you are afraid, your heart races, your mouth goes dry and your palms sweat. You do not choose these changes; they happen on their own.
The second component is the subjective experience — the private, conscious feeling itself. This is what the emotion feels like from the inside, and only the person having it can truly know it.
The third component is the overt expression — the outward, observable signs of the emotion. A smile, a clenched fist, a trembling voice or tears in the eyes all reveal to others what a person is feeling.
Diagram

Emotions are sometimes confused with moods, but the two are different. A mood is a longer-lasting, milder feeling-state that usually has no single clear cause.
4.1.2 Characteristics of Emotion
Emotions share several features across people and situations. Knowing these characteristics helps us see why emotional life is so varied and yet so recognisable.
Emotions are universal. They are found in all human beings, and in simpler forms in animals too. A frightened cat and a frightened child both freeze and widen their eyes.
Emotions are subjective. Even when two people face the same event, each experiences the emotion in a personal way. A birthday party may thrill a sociable person yet exhaust a shy one.
The link between a stimulus and an emotion is not fixed. The same stimulus can produce different emotions in different people, and different stimuli can produce the same emotion. A student may feel the same sadness whether he fails a test or loses a valued possession.
Emotions rise suddenly but fade slowly. Anger can flare in an instant, yet the irritation may linger for hours after the cause has passed.
Every emotion involves both the inner arousal of the body and some outward expression. This is why a strong feeling is so hard to hide completely.
Emotions can be displaced. Displacement means redirecting a feeling from its real cause to a safer target. A person scolded by a superior at work may come home and snap at a younger sibling.
Intense emotion can also cloud clear thinking. When feelings run very high, careful judgement and decision-making tend to suffer — a point we will meet again when we study how arousal affects performance.
4.1.3 Subjective and Cognitive Experience
We have seen that emotion is deeply personal. Let us look more closely at its subjective side and at how it is tied to thinking.
The subjective experience of emotion is unique to each individual and has many shades. Psychologists often measure it as a person’s subjective well-being — their own overall judgement of how happy and satisfied they feel with life.
Emotions are also multidimensional. The same event can pull a person in several directions at once. Starting at a new school may bring excitement and nervousness together.
Emotion and thinking are closely linked, and the influence runs both ways. Here, cognition means the higher mental activities of thinking, remembering, attending and interpreting.
Emotion shapes cognition. When we are in a cheerful mood, pleasant memories come easily and the world looks brighter. When we are low, unpleasant thoughts crowd in and colour how we see everything.
Cognition also shapes emotion. Often a bodily stir is vague, and we must interpret the situation to know what we are feeling. This interpretation is called cognitive appraisal.
Appraisal draws on our schemas — the stored concepts and ideas built up from past experience. Meeting a barking dog, a person who was once bitten appraises danger and feels fear, while a dog-lover appraises play and feels delight.
4.1.4 The Physiological Basis and Overt Expression of Emotion
Behind every emotion lies a busy body. Some of this activity is covert, hidden inside like a change in blood chemistry, and some is overt, open and observable like a flushed face. Let us trace where these changes begin.
The Brain and Emotion
Four regions of the brain play leading roles in emotion.
The thalamus sits deep in the brain and acts as a relay station. It receives incoming information from the senses and passes it on to other areas for further handling.
The hypothalamus, a small structure below the thalamus, regulates many involuntary responses. It helps drive changes such as heart rate, body temperature and hormone release during emotion.
The limbic system is a group of connected structures that governs our basic emotions and drives. Within it, a small almond-shaped part called the amygdala is especially important for fear and for detecting threat quickly.
The cerebral cortex is the brain’s thin outer layer, responsible for higher thinking. It interprets situations and lets us understand, name and control our emotions rather than simply react to them.

The Autonomic Nervous System
Many bodily changes in emotion are managed by the autonomic nervous system — the part of the nervous system that controls involuntary functions such as heartbeat and digestion. It has two divisions that work in opposite ways.
The sympathetic division prepares the body for action. During fear or anger it speeds the heart, raises blood pressure, widens the pupils and readies the muscles — the familiar “fight-or-flight” response.
The parasympathetic division calms the body afterwards. It slows the heart and restores the body’s steady internal balance, a state called homeostasis.
Overt Expressions of Emotion
The visible signs of emotion are its overt expressions. They are the main way we communicate feelings without words — through facial expressions, body movements and posture.
Common overt expressions include a flushing (reddening) of the face in anger, or a paling of the face in fear. Others are widening of the pupils, goosebumps, sweating, trembling of the hands, a choking or changed voice, and a faster pulse.
Changes in facial expression carry the most information. Raised eyebrows, a frown, a smile or tears each signal a different emotional state to those around us.
4.1.5 The Primary Emotions
Psychologists distinguish a small set of primary emotions — basic emotions that appear early in life, are shared across cultures, and seem to be part of our inherited make-up. More complex emotions, such as pride or jealousy, are seen as blends of these, built up through experience.
Five primary emotions are central to human life: fear, anger, joy, sorrow and affection.
Fear
Fear is triggered by perceived danger or threat. It readies the body to flee, hide or freeze. Though unpleasant, fear has clear survival value, because it pushes us to avoid or escape harm.
Anger
Anger arises when our goals are blocked, or when we sense a wrong or unfairness. It ranges from mild irritation to intense rage. Anger needs to be expressed in controlled, socialised ways, since uncontrolled anger harms both relationships and health.
Joy
Joy is a positive emotion of pleasure and satisfaction. It usually follows the fulfilment of a wish or need. Unlike fleeting happiness, joy tends to leave a lingering glow and a general sense of contentment.
Sorrow
Sorrow is a negative emotion of deep distress caused by loss, disappointment or misfortune. Its intensity varies with the size of the loss, and it is often felt over a long period, as in grief.
Affection
Affection is a positive emotion of warmth, liking and attachment towards others. It is expressed through tenderness and care, and is closely tied to love. Affection builds the bonds that hold families and friendships together.
Are these exactly the “correct” basic emotions? Psychologists still debate the list.
One striking fact supports the whole idea of primary emotions — people the world over show and read them in much the same way.
4.2 Theories of Emotion
Everyone agrees that an emotional episode contains four ingredients: a stimulus, bodily arousal, a subjective feeling and some behaviour. Where the great theories disagree is over the order in which these occur, and which one causes which.
Common sense says the order is obvious. You see a snake, you feel afraid, and then your body reacts. Yet the three theories in this section each challenge that comfortable picture in a different way.
4.2.1 The James–Lange Theory
This earliest theory was put forward almost at the same time by the American psychologist William James and the Danish physiologist Carl Lange. Their similar views were later combined under one name.
The theory turns common sense upside down. It claims that the bodily reaction comes first, and that the emotion is simply our awareness of that reaction. We do not tremble because we are afraid; we feel afraid because we notice ourselves trembling.
The sequence runs in three steps. First we perceive the emotion-provoking situation. Then the body reacts with arousal and behaviour. Finally, we sense those changes and recognise the emotion.
Diagram
Fig. 4.2-1 – a left-to-right sequence: emotion-provoking situation → physiological and behavioural response (heart pounding, trembling, running) → identification of the emotion (fear)
James summed it up in a famous line: “We feel sorry because we cry, angry because we strike, afraid because we tremble.”
Support for the theory comes from everyday observation. If you deliberately relax your body and soften your face, anger often fades. If you force a smile, your mood can lift a little. Changing the bodily response seems to change the feeling.
The theory was strongly criticised by Walter Cannon. His main objection was simple but powerful: the same bodily arousal — a racing heart and fast breathing — accompanies fear, anger and excitement alike, so the body alone cannot tell us which emotion we are feeling.
4.2.2 The Cannon–Bard Theory
Walter Cannon, an American physiologist, proposed an alternative that was later refined by Philip Bard. It rejects the idea that one event causes the other.
According to this theory, the bodily arousal and the conscious emotion happen at the same time and independently. Neither one causes the other; they simply occur together.
Cannon stressed the role of the thalamus deep in the brain. When we perceive a situation, the thalamus sends the information along two paths at once — one to the cerebral cortex, which produces the conscious feeling, and one to the hypothalamus and autonomic nervous system, which produce the bodily changes.
Diagram
Fig. 4.2-2 – a stimulus feeding into the thalamus, which then splits into two simultaneous branches: one to the cerebral cortex (conscious emotion is felt) and one to the hypothalamus and autonomic nervous system (bodily arousal occurs)
The theory fits two everyday facts well. Emotions can be felt almost instantly, far faster than slow bodily changes could explain. And very different emotions can share nearly the same bodily state.
Its weakness is the opposite of James–Lange’s. By treating emotion as a near-automatic brain event, Cannon–Bard gave too little weight to how our thoughts, interpretations and past experiences shape what we feel. It also leaned heavily on animal experiments and overstated the role of the thalamus alone.
4.2.3 The Schachter–Singer Theory
A more complete theory was later offered by the American psychologists Stanley Schachter and Jerome Singer. It is often called the two-factor theory because it says emotion is built from two things working together.
The two factors are general bodily arousal and a cognitive label. Arousal on its own is vague — a pounding heart could mean many things. To turn it into a specific emotion, the mind looks at the situation and attaches a label to the arousal.
The sequence therefore has an extra step. We perceive the situation, general arousal occurs, we interpret that arousal in the light of the surroundings, and only then do we experience a particular emotion.
Diagram
Fig. 4.2-3 – a left-to-right sequence: emotion-provoking situation → general bodily arousal → cognitive label drawn from the situation → specific emotion is experienced
This is why the same racing heart can be read in opposite ways. In a dark, lonely lane it is labelled “fear”; on a roller-coaster, surrounded by laughing friends, the very same arousal is labelled “excitement”.
4.3 Motivation: Needs, Drives and Instincts
4.3.1 What is Motivation?
Why does one student rise before dawn to practise cricket, while another spends the same hours on a science project? In both cases, something inside is pushing them to act. That inner push is what psychologists call motivation.
Motivation is the internal process that starts, directs and sustains behaviour towards a goal. A single reason or inner state behind a particular action is called a motive.
Motivation has three components. Activation is the decision to begin an action, such as opening a book to study. Persistence is the effort to keep going in spite of obstacles, such as continuing to study even when the topic is hard. Intensity is the energy and vigour put into the effort.
We cannot see motivation directly, because it is an inner state. We infer it from a person’s behaviour — from what they choose to do, how long they keep at it, and how much energy they show.
Motivation draws on biological, emotional, social and cognitive forces. As we saw earlier, emotion and motivation are close partners, since our feelings often supply the drive behind what we do.
4.3.2 Needs, Drives and Homeostasis
Much motivation begins with a need. A need is a lack or deficiency of something the body or mind requires, such as food, water, warmth or company.
A need creates an uncomfortable state of tension. This tension arouses a drive — an inner push that energises the person to act in order to reduce the tension.
The whole process runs as a cycle. A deficiency creates a need; the need builds tension and a drive; the drive powers goal-directed behaviour; the goal is reached; the need is satisfied and the drive falls away. The body then returns to balance, the state of homeostasis met earlier.
Diagram
Fig. 4.3-1 – flow: deficiency (need) → state of tension (drive) → goal-directed behaviour → goal reached → need satisfied and drive reduced, with an arrow curving back to the start
Needs of this basic, bodily kind are called primary or biological needs, and they must be met again and again to keep us alive. Several biological drives shape our daily behaviour.
The hunger drive is largely regulated by the hypothalamus, working together with signals such as stomach contractions and the level of sugar in the blood. The thirst drive too is guided by the hypothalamus, prompted by a dry mouth and by the body’s water balance. Fatigue produces the drive for sleep, and the hypothalamus also helps control the sleep–wake rhythm.
The sexual drive is unusual among biological drives. Although rooted in the body and in hormones, it is not needed to keep the individual alive, even though it matters for the survival of the species.
4.3.3 Instincts
Not all motivated behaviour is learned. Some of it is built in from birth. An instinct is an inborn, unlearned tendency to behave in a fixed way in response to a particular stimulus, shared by all members of a species.
Instincts are easy to spot in animals. Birds build nests at the right season without being taught, and newborn animals seek their mother’s milk. Such behaviours appear without any practice or instruction.
Instincts are sometimes confused with reflexes, but they are not the same. A reflex is a simple, immediate response to a specific stimulus, such as blinking at a puff of air or the knee jerking when tapped.
Several psychologists placed instincts at the heart of motivation. William James argued that much human behaviour is guided by instincts, both social and biological. William McDougall used the word “instinct” to mean an inherited disposition that drives us to act.
Sigmund Freud gave instincts a central role. He proposed two basic instincts. Eros, the life instinct, urges self-preservation, love and reproduction, and is fuelled by a life energy he called libido. Thanatos, the death instinct, drives aggression and destruction.
Later psychologists grew doubtful about instinct theories. Simply naming an instinct for every behaviour does not really explain it, and much human conduct is clearly learned rather than fixed at birth.
4.3.4 Intrinsic and Extrinsic Motivation
Motivation can spring from inside the activity itself, or from something outside it. These two sources are called intrinsic and extrinsic motivation.
Intrinsic motivation is the drive to do something for its own sake, because the activity is interesting, enjoyable or satisfying in itself. Reading for pleasure, gardening, sketching or playing music for the joy of it are all intrinsically motivated.
Extrinsic motivation is the drive to do something for an outside reward or to avoid a punishment. Studying only for high marks, working mainly for money, or practising a sport chiefly to win a prize are extrinsically motivated.
Intrinsic motivation tends to grow when a task offers a fair challenge, sparks curiosity, gives the person a sense of control, and brings recognition of what they have achieved.
Interestingly, piling on external rewards can sometimes weaken the inner interest a person already had.
4.4 Theories of Motivation
We have seen what motivation is and where it begins. Psychologists have gone further and asked what actually generates and shapes it. Several theories try to answer this, each highlighting a different force behind our goal-seeking behaviour.
4.4.1 Push and Pull Theories
One useful way to sort the theories is to ask whether motivation comes from behind us or from ahead of us. This gives two families: push theories and pull theories.
A push theory says that inner drives push us into action. This is also called the drive theory or drive-reduction theory. When a need creates a drive, we are pushed to behave in ways that reduce it, and reducing the drive brings relief and satisfaction.
Think of a student who dislikes mathematics but must clear an entrance test. The inner drive to succeed pushes her to practise, and each solved problem eases the tension a little.
A pull theory says that outside goals pull us towards them. This is also called the incentive theory. An incentive is any external object or outcome that attracts us, such as a prize, a bonus, praise or a promotion.
Here the direction is reversed. We are not pushed from within; we are drawn towards something desirable in the environment. The nearer and more attractive the incentive, the harder we work to reach it.
4.4.2 Optimum Arousal Theory
Not all behaviour aims at reducing arousal. Sometimes we actually seek out excitement. Optimum arousal theory explains this.
The theory says that each person is motivated to keep arousal at a comfortable level — an optimum arousal that is neither too low nor too high. Too little stimulation feels dull; too much feels overwhelming.
When arousal drops too low, we look for stimulation, perhaps by meeting friends or playing a game. When arousal climbs too high, we seek calm, perhaps by resting or taking a quiet walk.
This optimum level differs from person to person. Some people are content with low-arousal activities like reading, while others crave high-arousal thrills such as car racing or paragliding.
The link between arousal and performance was captured by Robert Yerkes and John Dillingham Dodson in what is now called the Yerkes–Dodson law.
The relationship forms an upside-down U. Very low arousal leaves us listless and unfocused; a moderate level sharpens us; very high arousal brings anxiety and tension that spoil performance.
Diagram
Fig. 4.4-1 – an inverted-U curve with arousal on the horizontal axis (low to high) and performance on the vertical axis (low to high); performance peaks at a moderate “optimum” level of arousal and falls off on either side
The best level of arousal also depends on the task. Difficult, complex tasks are performed best at a lower level of arousal, because high arousal disrupts careful thinking. Simple, well-practised tasks can tolerate higher arousal.
4.4.3 Expectancy Theory
The expectancy theory was proposed by Victor Vroom. Unlike theories built on needs, it says motivation is governed by what we expect to gain from our effort.
According to this view, we channel effort into a task when we expect it to lead to a valued reward. The stronger and clearer that expectation, the stronger the motivation.
Vroom said motivation depends on three elements working together. Expectancy is the belief that one’s effort will actually lead to good performance. Instrumentality is the belief that good performance will actually be rewarded. Valence is the value the person places on that reward.
The three combine by multiplication:
\[\text{Motivation} = \text{Expectancy} \times \text{Instrumentality} \times \text{Valence}\]
Because the elements are multiplied, if any one of them falls to zero, motivation collapses. A student who believes her effort will not raise her performance (expectancy of zero) will not be motivated, however valuable the reward. The same is true if she doubts the reward will ever come, or if she does not want the reward at all.
Diagram
Fig. 4.4-2 – three linked boxes multiplied together: Expectancy (“Will my effort lead to good performance?”) × Instrumentality (“Will good performance be rewarded?”) × Valence (“Do I value the reward?”) → Motivation
4.4.4 Maslow’s Need Hierarchy
The best-known theory of motivation is the hierarchy of needs, proposed by Abraham Maslow. He argued that human needs are arranged in levels, and that we climb from the lower to the higher.
Maslow set out five levels of need in a pyramid. The most basic needs sit at the base, and the most complex at the top. In general, a lower level must be reasonably satisfied before the next becomes a strong motivator.
Diagram
Fig. 4.4-3 – Maslow’s five-tier pyramid, base to apex: Physiological needs (food, water, sleep); Safety needs (security, stability); Belongingness and love needs (friendship, family); Esteem needs (respect, achievement); Self-actualisation (realising one’s potential). The lower four levels are marked as “deficiency needs” and the top as a “growth need”
At the base are the physiological needs — food, water, air and sleep — without which life cannot continue. Above them come the safety needs, for security, stability and freedom from fear. Together these two form the basic needs.
Next are the belongingness and love needs, also called social needs — the need for friendship, family, affection and acceptance. Above them are the esteem needs, for self-respect, achievement, status and the respect of others. Together, esteem and love needs are the psychological needs.
At the summit sits self-actualisation — the need to realise one’s full potential and become all that one is capable of becoming. Maslow believed few people fully reach it.
The five levels split into two groups. The lower four are deficiency needs, which arise from a lack and must be met to avoid distress. The top level is a growth need, which comes not from lack but from a wish to grow as a person.
4.6 Frustration and Conflict
4.6.1 Frustration: Meaning, Causes and Responses
Motivation does not always reach its goal. When our goal-directed behaviour is blocked, an unpleasant feeling arises. Psychologists call this feeling frustration.
The word comes from the Latin frustra, meaning “in vain”. Frustration is exactly that experience — of effort that seems to lead nowhere because a motive cannot find free or adequate expression.
Frustration can arise from inside or from outside the person. Internal, or personal, frustration develops when our own goals are blocked by our limits — a lack of skill, low confidence, or an inner conflict between motives. External, or environmental, frustration comes from obstacles in the surroundings, such as a sudden road block, a power cut or a long delay.
When people are frustrated, they respond in several typical ways. Knowing these responses helps us recognise and handle frustration in ourselves and others.
Diagram
Fig. 4.6-1 – “Frustration” at the centre with arrows out to five common responses: anger, loss of confidence, withdrawal, stress, and low mood
The most common response is anger, often shown as outbursts or other aggressive behaviour. Repeated failure can bring a loss of confidence, so that a person doubts their own ability. Some show withdrawal — giving up the goal and turning away, sometimes with apathy. Ongoing frustration may lead to stress, with its physical and mental strain, and at times to a lasting low mood.
4.6.2 Conflict Among Motives
One important internal cause of frustration is conflict. A conflict occurs when two or more opposing motives or goals pull us in different directions, and we must choose between them.
Psychologists describe several kinds of conflict. We will look at three that are common in everyday life, using a simple idea: a goal can either attract us (approach) or repel us (avoidance).
Diagram
Fig. 4.6-2 – three panels showing a person between goals: (1) approach–approach, a person between two positive goals; (2) avoidance–avoidance, a person between two negative goals; (3) multiple approach–avoidance, a person between two goals that each carry both positive and negative features
Approach–Approach Conflict
An approach-approach conflict arises when a person must choose between two attractive goals. Both pull us towards them, but we can have only one.
Suppose a talented footballer receives two equally appealing offers from two famous clubs. He can sign with only one, so accepting either means giving up the other. This is usually the mildest conflict and is resolved fairly easily.
Avoidance–Avoidance Conflict
An avoidance-avoidance conflict arises when a person must choose between two unpleasant options. Both repel us, yet one must be picked. This is the feeling of being caught between two evils.
For example, an employee may have to choose between a transfer to a remote place and being placed under a harsh supervisor. Neither is wanted, so the person feels stuck and may try to escape the choice altogether.
Multiple Approach–Avoidance Conflict
To understand the third type, we first need a simpler idea. Sometimes a single goal both attracts and repels us at once — it has good and bad features together. This is an approach-avoidance conflict. A dream job in a distant city attracts us with its career prospects but repels us with the thought of leaving home.
Now build on that. A multiple approach-avoidance conflict arises when a person must choose between two or more goals, and each goal carries both positive and negative features. This is the most complex conflict of all, because every option has to be weighed on several sides at once.
4.7 Summary
An emotion is a complex reaction to a stimulus made of three linked components: physiological arousal (bodily changes), subjective experience (the private conscious feeling) and overt expression (the observable outward signs).
Emotions are universal and yet subjective. The same stimulus can trigger different emotions in different people, and emotions can be displaced from their real cause onto a safer target.
Emotion and cognition influence each other both ways. Our mood colours what we notice and remember, while our cognitive appraisal — how we interpret a situation, drawing on stored schemas — decides which emotion we feel.
The brain’s role in emotion is shared: the thalamus relays information, the hypothalamus drives involuntary responses, the limbic system (with the amygdala) governs basic emotions, and the cerebral cortex interprets and controls them.
The autonomic nervous system produces the bodily changes of emotion. Its sympathetic division arouses the body for “fight-or-flight”, and its parasympathetic division calms it and restores homeostasis.
Overt expressions — facial changes, flushing or paling, pupil dilation, sweating, trembling and voice changes — are how emotions are communicated without words.
Five primary emotions are central to human life: fear, anger, joy, sorrow and affection. Their expression appears to be shared across cultures, as Ekman’s cross-cultural work suggested.
The three theories of emotion differ mainly in sequence. James–Lange holds that arousal comes first and the feeling is our awareness of it; Cannon–Bard holds that feeling and arousal occur at the same time; Schachter–Singer holds that general arousal is given a cognitive label from the situation, and that label is the emotion.
Motivation is the internal process that activates, directs and sustains behaviour towards a goal. It has three components: activation, persistence and intensity, and is inferred from behaviour rather than seen directly.
Motivated behaviour often follows a cycle: a need (deficiency) creates a drive (tension), which powers goal-directed behaviour; reaching the goal satisfies the need and reduces the drive, restoring homeostasis.
Instincts are innate, unlearned patterns of behaviour shared across a species. They differ from simple reflexes, and Freud proposed two great instincts — Eros (life) and Thanatos (death) — though instinct theory is now used cautiously.
Intrinsic motivation drives us to act for the enjoyment of the activity itself, while extrinsic motivation drives us to act for an outside reward such as money, marks or praise.
Push (drive-reduction) theory says inner drives push us to reduce tension, while pull (incentive) theory says outside rewards draw us forward.
Optimum arousal theory says we seek an ideal level of arousal, not the lowest. The Yerkes–Dodson law shows performance is best at a moderate level of arousal, and that harder tasks are performed best at lower arousal.
Vroom’s expectancy theory says motivation is the product of expectancy, instrumentality and valence (\(M = E \times I \times V\)); because they multiply, if any one is zero, motivation collapses.
Maslow arranged human needs in a five-level hierarchy — physiological, safety, belongingness and love, esteem, and self-actualisation — with lower needs generally satisfied before higher ones motivate. The lower four are deficiency needs and self-actualisation is a growth need.
Social motives are learned from the social environment. Achievement motivation is the drive to accomplish difficult tasks well; power motivation is the drive to influence and control others.
Aggression is behaviour meant to harm another who wishes to avoid it. It may be hostile (harm is the aim) or instrumental (harm is a means to another goal), and much of it is learned by observing models, as Bandura’s Bobo doll study showed.
Aggression usually ends in a lose–lose outcome. It can be curbed through fair punishment, healthy outlets, counselling and de-escalation, though simply “venting” does not reliably reduce it.
Frustration is the unpleasant state that arises when a motive is blocked. It has internal causes (personal limitations, conflict) and external causes (obstacles in the environment), and people respond with anger, loss of confidence, withdrawal, stress or low mood.
Conflict among motives is a major internal cause of frustration. Its three types are approach–approach (two attractive goals), avoidance–avoidance (two unpleasant goals) and multiple approach–avoidance (two or more goals that each carry both positive and negative features).

4.9 Points to Ponder
We can feel afraid before we know why, yet we can also talk ourselves out of a fear by rethinking a situation. Over our emotions, which finally has more power — the body or the mind?
Rewards can sometimes weaken the very interest they were meant to strengthen. Should parents and teachers reward children for reading, or does paying for a pleasure risk turning it into a chore?
Maslow placed self-actualisation above belonging on his ladder of needs. In a society that prizes family and community, does that ordering still hold, or should the ladder be redrawn?
If aggression is largely learned by watching others, how much responsibility do films, games and social media bear for the aggression we see around us?
A little arousal sharpens performance, but too much spoils it. Before an important match or examination, is it wiser to calm down completely, or to hold on to a little nervousness?
We treat frustration and conflict as unpleasant, yet they often push people to decide, grow and change. Could a life with too little frustration be as unhelpful as one with too much?

4.5 Social Motives
The drives we met earlier — hunger, thirst, sleep — are biological, and we share them with animals. Human beings also have motives that grow out of living together in society. These are the social motives.
Social motives are learned through interaction with family and society, rather than being present at birth. They are found widely across a community, and they have a striking feature: once satisfied, they tend to return, driving us on to the next goal.
Three social motives are often called distinctively human. They are the motives for achievement, for power, and — in its harmful form — aggression.
4.5.1 Achievement Motivation
Achievement motivation is a strong desire for success and for reaching a standard of excellence. People high in it are drawn to accomplishing difficult but manageable tasks.
Achievement motivation is the need to succeed, to master challenges and to reach a personal standard of excellence.
The idea was studied closely by David McClelland, who measured a person’s need for achievement using the Thematic Apperception Test. In this test, people write stories about ambiguous pictures, and the stories are scored for themes of striving and success.
People high in achievement motivation share a recognisable pattern of behaviour. They pick goals that are challenging yet realistic, they seek honest feedback, they take personal responsibility for outcomes, and they persist in the face of difficulty.
High Achievers vs Low Achievers | Feature | High achievers | Low achievers | |—|—|—| | Choice of task | Moderately challenging and realistic | Very easy or unrealistically hard | | Attitude to feedback | Actively seek and use it | Tend to avoid it | | Responsibility | Take personal responsibility | Blame luck or others | | Main concern | Personal accomplishment | Avoiding failure or chasing reward |
Achievement motivation is largely built in childhood through social learning. Children imitate the striving of those around them, and parents who expect effort and who praise hard work help the motive take root.
achievement motivation Meera could take an easy elective for a guaranteed high grade, but she chooses a demanding research project instead. She sets herself a tough target, asks her teacher for detailed feedback, and reworks her draft several times. When she succeeds, the pride she feels matters more to her than the marks. Meera’s choices show strong achievement motivation.
Along with achievement and power, McClelland also identified a need for affiliation — the wish to form warm, friendly relationships. It is a real social motive too, but the three studied in this chapter are the ones the syllabus highlights.
4.5.2 Power Motivation
Power motivation is the desire to influence, control or have an impact on other people. The idea was popularised by David McClelland, building on the earlier work of Henry Murray.
Power motivation is the desire to exert influence and control over other people, groups or society.
People high in this motive want to guide and direct others, and they care about prestige and reputation. They often seek positions of leadership or management, and some display status symbols to signal their standing.
Power can be turned in two very different directions. Used selfishly, it becomes a wish to dominate others for one’s own gain. Used well, it becomes the drive to influence people for the good of a group or cause — the kind of power a fair leader exercises.
The power motive drives many capable leaders, managers and public figures. Whether it helps or harms depends on how it is used — to serve a team and a community, or only to control others.
4.5.3 Aggression
The third social motive appears in its harmful form as aggression. Aggression is any behaviour intended to harm or hurt another living being who wishes to avoid it. The harm may be physical, as in an assault, or psychological, as in abusive words.
Aggression is any form of behaviour directed towards deliberately harming or injuring another living being who is motivated to avoid such treatment.
Psychologists distinguish two forms. Hostile aggression has harming the other as its sole aim. Instrumental aggression uses harm as a means to some other goal, such as winning or gaining control.
Hostile vs Instrumental Aggression Hostile aggression aims only to hurt (lashing out in rage). Instrumental aggression uses harm as a tool for another end (a bully who intimidates classmates to get their lunch money).
forms of aggression During a heated match, one player shoves an opponent purely out of anger after a foul — this is hostile aggression. In another team, a player deliberately blocks a rival roughly to stop a certain goal and win the game — this is instrumental aggression. Both cause harm, but the goals behind them differ.
Causes of Aggression
Aggression has several causes, and psychologists have explained it in different ways.
Some see it as rooted in instinct. Freud linked aggression to the death instinct, Thanatos, met earlier in the chapter. Others trace it to frustration — aggression often follows the blocking of a goal, a link we explore in the next section.
A powerful explanation is social learning. Aggressive behaviour is frequently learned by watching and copying others — family members, peers, and models seen in the media.
Bandura — the Bobo doll experiment Question: Can aggression be learned simply by watching another person? Method: Young children watched an adult either behave aggressively towards a large inflatable “Bobo” doll, or play calmly beside it. Each child was later left alone with the doll. Finding: Children who had watched the aggressive adult were far more likely to hit and kick the doll themselves, often copying the exact actions they had seen. Meaning: Aggression can be learned through observation and imitation of models. The study also raised ethical concern about deliberately exposing children to aggressive behaviour.
Aggression can also be strengthened by reinforcement — when aggressive acts are rewarded, they are repeated. Biological factors and, at times, obedience to a harmful authority can play a part as well.
Effects of Aggression
Aggression rarely benefits anyone in the end. It usually leads to a lose–lose outcome, in which neither the victim nor the aggressor is left satisfied.
The victim is harmed and wronged. The aggressor, too, tends to become disliked, feared and isolated, as others keep their distance. Left unchecked, aggression can escalate and spill into wider conflict.
Control and Management of Aggression
Because much aggression is learned, it can also be reduced and managed. Several approaches are used.
Punishment can discourage aggression, but only if it is just, prompt and aimed at the true aggressor. Wrongly directed or unfair punishment can increase resentment and aggression instead of reducing it.
Catharsis — releasing pent-up feelings through activities such as sport or exercise — is often suggested. It is worth noting, however, that research on catharsis is mixed, and simply “venting” anger does not reliably calm it.
Psychological methods are also valuable. Cognitive therapy helps people change the thoughts behind their aggression, relaxation techniques such as yoga and breathing exercises ease tension, and counselling addresses the root causes. Skilled de-escalation — calm words and a chance to be heard — can defuse a tense situation before it turns violent.
language and labelling We speak of a person who behaves aggressively, not an “aggressive type” fixed for life. Because much aggression is learned, it can be unlearned. Labelling a person as permanently violent is unfair and can even make change harder.
