What psychology is, what it studies and where psychologists work

What this chapter is for

This chapter answers the first question of the subject, which is what psychology is. By the end you will be able to define it in words an examiner trusts, explain the two things it studies and the four goals it pursues, name its main branches and say what each does, tell a psychologist from a psychiatrist or a counsellor, and say where psychologists work, in the world and in Pakistan. You will also be able to say why some people doubt that psychology is a science, and how psychologists answer them.

It is the ground every later chapter stands on. Its first half sets out the definition, what psychology studies, its goals and how the definition changed. Its second half maps the branches and the neighbouring fields, the places psychologists work, the critics and where the field stands now. The history of psychology’s schools is taught in its own chapters, and this one tells only as much of it as a definition needs.

FPSC set this ground directly in CE-2025, asking for “the nature and scope of psychology as a scientific discipline”, and indirectly in CE-2018 and CE-2022, which asked about the place of the mind in psychology and the field’s key issues.

Before you start

The words

• Psychology. The scientific study of the mind and behaviour. The word comes from two Greek words, psyche (the soul or the mind) and -logia (the study of).
• Behaviour. Anything a person or an animal does that can be observed: walking, speaking, crying, pressing a button, a racing heart that a machine can record.
• Mental processes. What goes on inside a person and cannot be seen directly: thinking, remembering, feeling, wanting, dreaming, perceiving.
• Scientific. Built on evidence that has been collected in a careful, open way and can be checked by someone else, rather than on opinion or authority.
• Branch (or field). One part of psychology that studies one kind of question, such as developmental psychology, which studies how people change across life.
• Applied psychology. Psychology used to solve a real problem, in a clinic, a school, a company or a court.
• Psychiatrist. A medical doctor who has trained further in mental illness. Unlike most psychologists, a psychiatrist can prescribe medicine.
• Clinical psychologist. A psychologist trained to assess and treat mental disorders with tests and talking therapies.

The places and the people

• Leipzig. A university city in Germany, where Wilhelm Wundt opened a laboratory for psychology in 1879. That is the date usually given for the birth of psychology as a separate science.
• Wilhelm Wundt (1832 to 1920). The German scientist often called the first psychologist.
• William James. An American, the other founder of psychology as a university subject, author of The Principles of Psychology (1890).
• John B. Watson. The American who in 1913 argued that psychology should study behaviour alone.
• The American Psychological Association (APA). The largest professional body of psychologists in the United States. Its dictionary’s definition of psychology is the one this subject uses.
• The University of the Punjab, Lahore. Its Institute of Applied Psychology began in 1962 as a Department of Applied Psychology.

The story in plain words

1. People have always wondered why we think, feel and act as we do. For centuries the question belonged to philosophers and religious scholars.
2. In the nineteenth century, scientists began to test these questions with experiments instead of argument. Wundt’s laboratory of 1879 is the usual starting date.
3. At first psychology studied the mind. Then, for about fifty years, many psychologists said it should study only behaviour, because the mind cannot be seen.
4. From the 1950s, psychologists brought the mind back, now studied with careful experiments. Today psychology studies both the mind and behaviour.
5. It has many branches. Some find things out, about the brain, memory, children or groups. Others use what is found, to treat illness, teach children, choose workers or help the courts.
6. A psychologist is not the same as a psychiatrist. A psychiatrist is a medical doctor and can give medicine; most psychologists use tests and talking therapies.
7. Pakistan has taught psychology since its early years, and more and more Pakistani universities train psychologists. A law to register them has been debated in Parliament but has not yet been passed.
8. Some critics doubt that psychology is a real science. Psychologists answer that its methods are scientific, while admitting that some findings have not held up and that much research has studied too narrow a slice of humanity.

1. What psychology is

Picture a young woman in Multan preparing for the CSS examination. A month before the paper she cannot sleep, her heart races when she opens a book, and she keeps thinking that if she fails, her family’s sacrifices will have been for nothing. Her cousin says she is simply weak. Her aunt says she has been touched by the evil eye. Her friend says everyone feels this way and she should ignore it. Each of them has an explanation. None of them has tested it.

Psychology is what happens when that question is asked in a different way. A psychologist would want to know how common this fear is among candidates, what happens in the body when it strikes, which thoughts make it worse, whether it can be predicted, and which ways of helping actually work, as shown by evidence that others can check. The question is the same as the cousin’s and the aunt’s. What changes is the method.

That is why the standard definition puts the word “scientific” first. The American Psychological Association’s dictionary defines psychology as “the scientific study of the mind and behavior.”¹ The definition has three parts, and each matters. Scientific says how psychology knows what it claims, by careful observation, experiment, testing and analysis, not by opinion or authority. Mind covers the inner life that cannot be seen directly, the thinking, remembering and feeling. Behaviour covers what can be seen, from speech to a racing heart. The same dictionary entry adds that psychology emerged “from philosophy into an empirical science”, meaning a science built on observation and evidence.¹

Many textbooks put the same idea in slightly different words, as “the scientific study of behaviour and mental processes”. The two definitions mean the same thing. “Mind” and “mental processes” are two names for the inner life, and every modern definition joins it to behaviour. When you define psychology in the hall, give the definition, name where it comes from, and then explain its three parts as above. That is worth more than a long definition learned by heart.

The word itself is older than the science. It joins the Greek psyche, meaning “soul” or “mind”, and -logia, meaning “study of”.¹ For most of history the study of the soul was a task for philosophers and religious scholars, in Greece, in the Muslim world and in Europe. Psychology as a separate science, with its own laboratories, is much younger, and the section on how the definition changed tells that part of the story.

A definition also tells you what is outside a subject. Psychology is not the study of the soul in the religious sense, which belongs to theology. It is not the study of societies as wholes, which belongs to sociology, though the two meet often. It is not the same as medicine, though it works beside medicine in hospitals. It studies the individual person, and sometimes the animal, thinking, feeling and acting, in the world they live in.

2. Behaviour and mental processes, the two things psychology studies

The definition names two things, and the difference between them shaped the whole history of the subject. So it is worth being exact about each.

Behaviour is anything a person or an animal does that someone else can observe and record. Speaking, walking, smiling and crying are behaviour. So is pressing a button in a laboratory when a light flashes, choosing one product over another in a shop, or answering a question on a test. Some behaviour is inside the body but can still be measured from outside, such as the heart rate, the sweat on the skin and the electrical activity of the brain. Psychologists count all of these as behaviour because a second observer, or a machine, can record them and check the record.

The great advantage of behaviour is that it can be measured. If a teacher says a child is “restless”, one observer may agree and another may not. If a psychologist counts how many times the child leaves his seat in an hour, two observers can count the same thing and compare. That habit of turning a vague word into something countable is one of the first things a psychologist learns.

The second thing psychology studies is harder to pin down. Mental processes are the inner events that cannot be seen directly, such as perceiving a face, remembering a phone number, solving a sum, feeling afraid, wanting food, imagining tomorrow, dreaming at night. The person having them knows they are happening. No one else can see them.

The difficulty is obvious. How can a science study what it cannot observe? Psychology’s answer is to study mental processes through what they make people do. A psychologist cannot see memory, but can show a person a list of words, wait twenty minutes and count how many are recalled. She cannot see fear, but can measure the heart rate, watch the face and ask the person to rate the fear from one to ten. Each of these is an observable sign of an inner process. By designing the right task, the psychologist makes the invisible leave a trace that can be measured.

Behaviour without mental processes leaves out most of what matters about people. Two candidates may both stay awake all night before the paper, one because she is anxious and the other because she is excited. The behaviour is the same and the meaning is opposite. Mental processes without behaviour cannot be tested, because a claim about the inner life that leaves no trace in what people do cannot be checked by anyone. Modern psychology therefore studies both, and studies each through the other.

There is a second way to see what psychology studies. Any behaviour can be explained at more than one level. Take the young woman in Multan again.

At the biological level, her fear is a body preparing for danger, with a racing heart, stress hormones and poor sleep. At the psychological level, it is a thought, the belief that failure would be a disaster for her family, and the feelings that follow from it. At the social and cultural level, it is the pressure of a family’s hopes and of the prestige the CSS carries in Pakistan. None of these explanations is the right one. Each is true at its own level, and a full explanation uses all three. Modern psychology calls this joined view the biopsychosocial approach, and the chapter on models of psychology teaches it in full.⁴

3. The four goals of psychology

Psychology studies the mind and behaviour for a purpose, and textbooks usually describe that purpose as four goals, one built on another. They are to describe, to explain, to predict and to change (some books say “control”) behaviour and mental processes. Work them through on the candidate’s fear and each becomes clear.

Describing comes first, because nothing can be explained before it is known exactly. A psychologist describing exam fear would ask how many candidates feel it, how strongly, at what point before the paper, and with what signs in the body and in the mind. Description answers the question “what happens?”

Explaining asks why. Here the psychologist proposes a cause and tests it. One explanation, which the chapters on emotion and on therapy return to, is that fear grows when a person believes that failure would be a disaster rather than a setback. Explanation is where theories live, and a theory earns its place only when evidence supports it.

Predicting follows from a good explanation. If fear rises with the belief that failure is a disaster, then fear should peak when that belief is strongest, in the week of the written examination, and in candidates who hold the belief most firmly. A prediction that comes true supports the explanation. One that fails sends the psychologist back to think again.

Changing, or controlling, is the goal that makes psychology useful. If the explanation is right, then helping a candidate to question the disaster thought should lower her fear. A clinical psychologist does exactly this, and the chapter on cognitive-behavioural therapy teaches how.

Watson, the founder of behaviourism, put two of these goals at the centre of the science. He wrote in 1913 that psychology’s “theoretical goal is the prediction and control of behavior.”⁸ The word “control” can sound threatening, as if psychologists wanted to steer people against their will. In practice it means changing behaviour for the better with the person’s agreement: helping a child learn to read, a patient overcome a phobia, a factory reduce accidents. The ethical codes of psychology, which later chapters teach, exist precisely to keep that change within the person’s consent.

4. How the definition changed: mind, behaviour, and both

The definition of psychology has not always been the one the APA gives today. It changed twice, and knowing why helps a candidate answer the question CE-2018 asked about the place of “the mind” in psychology.

Before the nineteenth century, questions about the mind were part of philosophy and religion. Wilhelm Wundt, a German scientist, set out to answer them by experiment. In 1879 he set up a laboratory for psychology at the University of Leipzig, where he and his students measured, among other things, how quickly a person reacts to a light or a sound, to a thousandth of a second.³ That date is the one usually given for the birth of scientific psychology, and it is the answer to a Part-I question set in CE-2024, which asked in which country the first psychology laboratory was established.²⁰

For Wundt, psychology was the scientific study of conscious experience. His main method was a trained kind of self-observation called introspection, in which a person reports, as carefully as possible, what they experience when shown a stimulus.³ In America, William James defined the subject in much the same spirit. His The Principles of Psychology (1890) opens with the sentence “Psychology is the Science of Mental Life, both of its phenomena and of their conditions.”⁷ He went on to name those phenomena as “such things as we call feelings, desires, cognitions, reasonings, decisions, and the like”.⁷

Introspection had a weakness that grew harder to ignore. Two trained observers could report different experiences of the same stimulus, and no one could check which was right, because no one else could see inside either of them. In 1913 John B. Watson drew a radical conclusion. Psychology, he wrote, “as the behaviorist views it is a purely objective experimental branch of natural science”, and “Introspection forms no essential part of its methods”.⁸ If the mind could not be observed, the science should study only what could be, which was behaviour.

Watson’s view, behaviourism, dominated American psychology for roughly the next half century. It produced some of the most solid findings in the field, about how animals and people learn, and the chapters on learning teach them. But it left out thinking, memory and feeling, which most people regard as the heart of what psychology should explain.

The mind did not stay out for long. From the 1950s, new work in linguistics, computer science and the study of the brain revived interest in the mind as something science could study.³ The shift is known as the cognitive revolution. The new psychologists did not return to introspection. They studied memory, attention and language with the careful experiments behaviourism had taught them, measuring what people did in order to infer what was happening inside.

The result is the definition used today, which keeps both halves of the story, “the scientific study of the mind and behavior.”¹ It keeps the mind, which Wundt and James studied, and it keeps the insistence on observable evidence, which Watson demanded. When CE-2018 asked “To what extent in the twenty-first century you justify the role of ‘the mind’ in psychology?”, this history is the answer’s backbone. The mind is central again, but it is studied through what it makes people do.

5. The branches that find things out

Psychology is now so large that no one person masters all of it. The American Psychological Association alone has 54 divisions, each an interest group for one part of the field.² The parts can be sorted roughly into two kinds. Some branches mostly find things out about how the mind and behaviour work, and are sometimes called basic or research psychology. Others mostly put what is found to use, and are called applied psychology. This section takes the first kind.

Biological psychology, also called biopsychology or neuroscience, studies how the brain, the nerves, the hormones and the genes produce behaviour. It asks what happens in the brain when a person is afraid, and why damage to one part of the brain takes away speech while damage to another takes away memory. The second head of this syllabus belongs to it.

Cognitive psychology studies thinking, which covers attention, perception, memory, language, problem solving and decision making. CE-2024 asked candidates to “Explore the field of cognitive psychology by discussing key concepts such as memory, problem solving and decision-making”, and the chapters on memory and on decision making answer it.¹⁹

Developmental psychology studies how people change from conception to old age, in body, in thinking and in their relations with others. Piaget’s stages of thinking, which the paper has asked about, are its best-known theory.

Social psychology studies how other people change what we think, feel and do. It asks why we conform to a group, obey an authority, help a stranger or hold a prejudice. The ninth head of the syllabus is social psychology.

Personality psychology studies how people differ from one another in lasting ways, and why each person stays much the same across situations and years. Its theories, from Freud to the Big Five, are among the most-asked topics of the paper.

Experimental psychology is less a separate topic than a way of working, the careful testing of ideas under controlled conditions. Much of the work in the branches above is experimental, and the chapter on psychology as a science teaches the method.

6. The branches that put psychology to use

The applied branches take what research has found and use it to help people, organisations and the state.

Clinical psychology assesses and treats mental disorders, from anxiety and depression to schizophrenia, using psychological tests and talking therapies. It is the branch most people picture when they hear the word “psychologist”, and it is the largest applied branch. The eleventh head of this syllabus is clinical psychology.

Counselling psychology helps people with the ordinary difficulties of life, such as choosing a career, coping with a loss or repairing a relationship, rather than with severe illness. The line between it and clinical psychology is not sharp, and in practice the two overlap.

Educational psychology studies how people learn and how teaching can be improved, and school psychology applies it to individual children, for example by assessing a child who is falling behind. Much of the head on psychological assessment grew out of this work.

Industrial and organizational psychology, often shortened to I/O psychology, studies people at work. It asks how to choose employees, train them, motivate them, lead them and keep them well. The twelfth head of the syllabus is I/O psychology.

Health psychology studies how the mind and habits affect physical health. It asks why people smoke or skip their medicine, how stress raises the risk of illness, how patients cope with a chronic disease. It is the thirteenth head.

Forensic psychology brings psychology to the law, by assessing whether an accused person is fit to stand trial, advising on the reliability of eyewitnesses, working with offenders. It is the fourteenth head, and CE-2021 asked how it differs from forensic science.¹⁹

Other applied fields are growing. Sports psychology helps athletes perform under pressure. Environmental psychology studies how people affect and are affected by their surroundings. Community psychology works with whole neighbourhoods rather than with individuals. The chapter on recent trends returns to some of them.

7. Psychology and its neighbours

Psychology shares ground with several other fields, and the paper rewards a candidate who can say exactly where the borders lie. The commonest confusion is between three professions that all help people with mental distress.

The difference that matters most is the one in the third row. A psychiatrist is a medical doctor, and so can prescribe medicines. A clinical psychologist is trained in psychological tests and therapies, and usually cannot.⁶ In good practice the two work together. A person with severe depression may see a psychiatrist for medicine and a clinical psychologist for therapy, and the evidence the clinical chapters teach suggests that the two together often help more than either alone.

Psychology’s other neighbours are fields of study rather than professions. Sociology studies groups, institutions and whole societies, while psychology studies the individual within them. The two meet in social psychology, and a candidate who also knows sociology will find the same ideas, such as socialisation and norms, seen from the other side. Neuroscience studies the nervous system at every level, from the single cell to the whole brain; psychology uses its findings to explain behaviour. Philosophy asked many of psychology’s questions first, about the mind, knowledge and free will, and still debates some of them. Psychiatry, as above, is a branch of medicine. Knowing these borders helps a candidate answer questions about the “scope” of psychology, which is the word FPSC used in CE-2025.¹⁹

8. Where psychologists work, in the world and in Pakistan

Psychologists work wherever people’s minds and behaviour matter, which is almost everywhere. Some teach and do research in universities. Clinical psychologists work in hospitals, in clinics of their own and in centres for people with disabilities. Educational psychologists work in schools and in education departments. I/O psychologists work in companies and in the bodies that select and train staff. Forensic psychologists work with the police, the courts and the prisons. Others work for the armed forces, in advertising, in the design of computers and machines, and in government departments that need to know how people will respond to a policy.⁶

A candidate for the CSS meets applied psychology directly. FPSC’s own rules require every candidate called for the viva voce to “undergo psychological assessment, comprising written tests and group tasks, designed to assess abilities, attitude and personality characteristics of the candidates with special regard to their aptitude for the civil services.”¹⁸ No separate marks are given for it, but the rules say the 300 marks of the viva “also reflect the performance on psychological assessment.”¹⁸ The tests used for that assessment are built by the methods the head on psychological assessment teaches, and the use of tests to choose people is taught in the chapter on selection and training.

Pakistan itself has taught psychology since its early years. At the University of Karachi, a history published in 2021 records, clinical psychology was taught from 1956, and the University of the Punjab’s Centre for Clinical Psychology was set up in 1984 to train clinical psychologists.¹² The University of the Punjab’s Institute of Applied Psychology traces its own start to 1962, when it was founded as a Department of Applied Psychology.¹³ The Pakistan Journal of Psychological Research is published by the National Institute of Psychology at Quaid-i-Azam University, Islamabad.¹⁴ The same review counted, in clinical psychology alone, three universities offering a doctorate, eighteen offering an MS and ten offering a four-year BS honours degree, some of them the same universities.¹²

Training is one half of a profession, and the law that recognises it is the other. Unlike medicine, which has its own law and council, psychology in Pakistan has no national body set up by law to register psychologists. Parliament has debated one. On 9 July 2024 the National Assembly passed the Pakistan Psychological Council Bill, 2024, a private member’s bill “to provide for the establishment of Pakistan Psychological Council”.¹⁵ On 1 December 2025 a separate bill with the same aim, the Pakistan Psychological Council Bill, 2025, was introduced in the Senate and sent to its standing committee.¹⁶ The National Assembly’s list of Acts, read in October 2026, contains no such Act.¹⁷ Until one is passed, who may call themselves a psychologist is settled by universities and professional bodies rather than by law.

This gap matters for the people psychologists serve. A patient cannot easily check whether the person treating her is trained, and a trained psychologist has no legal standing that sets her apart from an untrained one. A candidate writing about psychology in Pakistan can name the gap as a policy problem with a remedy, which is exactly the remedy the bills propose, a statutory council that sets standards and keeps a register.

9. Psychology, common sense and faith

Many people believe that psychology only dresses common sense in long words. It is worth testing that belief, because the answer shows what makes psychology a science.

Common sense says “birds of a feather flock together”, and it also says “opposites attract”. It says “absence makes the heart grow fonder”, and also “out of sight, out of mind”. Common sense can explain any result after the event, because it holds a saying for every outcome. What it cannot do is tell you in advance which saying is true in which situation. That is what research does. Research on friendship and marriage finds that people are more likely to become friends or partners with someone similar to them in background, attitudes and way of life, and has found no evidence that opposites attract.⁵ On this question the first saying wins and the second loses. Common sense was not wrong to raise the question. It simply could not settle it.

The young woman’s relatives in Multan offered common-sense explanations of her fear, and some offered religious ones. Psychology does not set out to replace faith, which answers questions about meaning and purpose that a laboratory cannot. It asks a narrower question. Of the explanations for this fear, which ones does the evidence support, and which ways of helping actually help? The two can sit side by side. A psychologist can respect a family’s faith and still ask which ways of helping the evidence supports, and many psychologists in Pakistan work in exactly that way.

10. Is psychology really a science? The critics

Psychology calls itself a science, and the definition puts the word first. Not everyone accepts the claim, and a candidate who can state the critics’ case fairly, and the answer to it, writes a far stronger answer than one who simply repeats the definition. Three criticisms carry weight.

The first criticism is that some findings have not held up. A science should produce findings that hold when other people repeat the study. In 2015 a large group of researchers, publishing as the Open Science Collaboration, repeated 100 studies that had appeared in three leading psychology journals. Ninety-seven per cent of the original studies had reported a statistically significant result, meaning one unlikely to be due to chance. Of the repeats, only 36 per cent did, and the effects found were on average half the size of the originals.⁹ The finding shook the field. It did not show that psychology is not a science, since the method of repeating studies to check them is itself the method of science. It did show that a single study, however famous, is weaker evidence than many students assume.

Psychologists have responded by changing how research is done. They now register a study’s plan before collecting data, share data openly, and repeat important studies before trusting them. The chapter on psychology as a science returns to this.

The second is that much research has studied too narrow a slice of humanity. In 2010, Joseph Henrich, Steven Heine and Ara Norenzayan pointed out that most findings in the behavioural sciences came from people in societies they called WEIRD, short for Western, Educated, Industrialized, Rich and Democratic. Their review found that such people are “frequent outliers”, unusual compared with the rest of humanity on measures from visual perception to fairness and moral reasoning, and concluded that they are “among the least representative populations one could find for generalizing about humans.”¹⁰ A theory tested only on American university students may not hold in a village in Sindh.

This criticism has special force for a Pakistani reader. It is a reason to ask, of every finding in this subject, whether it has been tested in Pakistan, and where it has, to give the Pakistani result.

A third criticism comes from Muslim psychologists themselves. Malik Badri argued in The Dilemma of Muslim Psychologists (1979) against the uncritical copying of Western psychology by Muslim scholars. As the description of its 2016 edition in Open Library’s catalogue puts it, the book warns against “the unthinking repetition and blind copying of Western, non-Islamic ideas and practices”, using the Prophet’s image of following others even into a lizard’s hole, while arguing that many techniques of modern psychology can be separated from their anti-religious roots and used well by Muslims.¹¹ Badri’s case was not against psychology. It was that a Muslim psychologist should test what she borrows against her own faith and culture.

Each criticism, read carefully, is an argument for more science, not less. The failed repeats call for more careful studies. The narrow samples call for research in more places, Pakistan among them. Badri’s critique calls for testing borrowed theories against local life. A candidate asked whether psychology is a science can therefore answer with confidence. Its methods are scientific, its findings are only as strong as the evidence behind each one, and its critics have mostly made it better.

11. Where the field stands today

Psychology today is larger, more varied and more international than at any time in its history. It reaches from the study of single nerve cells to the study of whole communities, and its applied branches work in almost every part of public life. The APA’s 54 divisions show the range, from experimental psychology to the psychology of trauma and of the media.²

Three movements shape the field now, and the chapter on recent trends teaches each. The first is the joining of psychology with neuroscience, as brain scanning lets researchers watch the living brain at work. The second is the push to study people across cultures, answering the WEIRD criticism with research in Asia, Africa and the Muslim world. The third is the open science movement that followed the failed repeats, which has changed how studies are planned, reported and checked.

In Pakistan the field is growing in universities and in demand. Mental health has become a subject of public discussion, and Parliament has twice taken up a bill to register psychologists. The main task ahead is the one those bills address, which is to set standards, so that a person who needs help can be sure the person giving it is trained.

12. What students mix up

Psychology and psychiatry. They are different professions with different training. A psychiatrist is a medical doctor and can prescribe medicine. A clinical psychologist cannot, and works mainly with tests and talking therapies.

Psychology and common sense. Common sense offers an explanation for every result after the event. Psychology tests which explanation holds before trusting it.

“Psychology is the study of the soul.” That is the meaning of the Greek word, not the modern definition. Psychology is the science of behaviour and of the mind behind it.

Psychology and clinical psychology. Clinical psychology is one branch, the most visible. Most psychologists in research do not treat patients at all.

Behaviour as only what people do on purpose. In psychology, behaviour includes anything observable, including a racing heart or a reflex that a machine records.

The 1879 date. It marks Wundt’s laboratory, the usual date for psychology as a separate experimental science. It is not the date psychology’s questions were first asked, which goes back to the ancient philosophers.

“Control” as a sinister word. In the goals of psychology, control means changing behaviour for the better, with the person’s consent, as when a therapist helps a patient overcome a fear.

13. What FPSC has asked

The ground of this chapter has been set in three papers.¹⁹

• CE-2025, Q.2: “Discuss the nature and scope of psychology as a scientific discipline. How has psychology evolved over time, and what are the major areas of study within the field?”
• CE-2022, Q.2: “What are the major approaches in contemporary psychology? What are psychology’s key issues and controversies?” The approaches are taught in the chapter on the modern perspectives; the definition and scope in this one.
• CE-2018, Q.2: “To what extent in the twenty-first century you justify the role of ‘the mind’ in psychology?”

Part-I has tested the history in this chapter. CE-2024 asked where the first experimental laboratory of psychology was established, and CE-2025 asked which term is used for the study of psychological development across the lifespan.²⁰

14. Facts to carry into the hall

15. What loses marks on this topic

A definition with no source. “Psychology is the study of behaviour” is incomplete and unsourced. Give the full definition, name the APA, and explain its parts.

A history that never reaches the present. Many answers to CE-2025’s question describe Wundt and stop. The question asked how psychology “evolved over time”, which means the swing to behaviourism, the return of the mind and the field today.

Scope as a list of names. Listing twelve branches earns little. Saying what each studies, with one example and the head of the syllabus it belongs to, earns much more.

Treating psychology and psychiatry as the same. It tells the examiner the candidate has not understood the field’s borders, which is what a question on “scope” tests.

Answering “is it a science?” with praise alone. The question rewards the critics’ case, stated fairly, and the answer to it.

16. A worked answer plan

The question is CE-2025, Q.2: “Discuss the nature and scope of psychology as a scientific discipline. How has psychology evolved over time, and what are the major areas of study within the field?”¹⁹

The tasks. Three. (1) The nature and scope of psychology as a scientific discipline. (2) How it evolved over time. (3) Its major areas of study.

Opening. Define psychology as “the scientific study of the mind and behavior” (APA), give the Greek roots, and say that its nature is scientific because it rests on observation, experiment and evidence that others can check.

Nature. Explain behaviour and mental processes and how the second is studied through the first; the four goals, worked on one example; the three levels of explanation.

Evolution. Wundt’s laboratory at Leipzig, 1879, and introspection; James’s “Science of Mental Life” (1890); Watson’s behaviourism (1913) and why it rejected the mind; the cognitive revolution from the 1950s; today’s definition that keeps both. A timeline diagram.

Scope and areas. A table of the branches in two columns, research and practice, each with the question it asks. Name the neighbours (psychiatry, sociology, neuroscience) and the borders between them.

Evaluation. Is it really a science? The failed repeats of 2015 and the WEIRD critique, and why each argues for better science; Badri’s call to test borrowed theories against local culture.

Pakistan. Clinical psychology taught at Karachi since 1956; the University of the Punjab’s department of 1962; FPSC’s own psychological assessment of candidates; the Psychological Council bills and the case for a statutory register.

Conclusion. Psychology is a young science with ancient questions. Its scope now runs from the nerve cell to the nation, and its strength is that it settles questions by evidence rather than by opinion.

What to remember from this chapter

• Psychology is “the scientific study of the mind and behavior” (APA). Scientific is the key word: evidence that others can check.
• Behaviour is what can be observed; mental processes are the inner life, studied through the behaviour they produce.
• Any behaviour can be explained at three levels, biological, psychological and social, and a full explanation uses all three.
• The four goals are to describe, explain, predict and change.
• The definition swung from conscious experience (Wundt, 1879; James, 1890) to behaviour alone (Watson, 1913) and back to mind and behaviour after the cognitive revolution of the 1950s.
• The branches divide roughly into research (biological, cognitive, developmental, social, personality) and practice (clinical, counselling, educational, I/O, health, forensic).
• A psychiatrist is a medical doctor and can prescribe medicine; a clinical psychologist works with tests and talking therapies.
• Critics point to failed repeats (2015), narrow WEIRD samples (2010) and, from within the Muslim world, the uncritical copying of Western theory (Badri, 1979). Each is an argument for better science.
• Pakistan has trained psychologists since the 1950s; a bill to register them passed the National Assembly in 2024 but is not yet law.
