What is Psychology?Class 11 Psychology Notes

Introduction

Psychology is a field that explores fundamental questions about human nature. It seeks to understand why people behave the way they do—why some individuals perform heroic acts, like Major HPS Ahluwalia climbing Mt. Everest despite being paralysed, while others engage in destructive behaviour. The discipline aims to contribute to human well-being by improving our understanding of ourselves and others.

Unlike other sciences, psychology focuses on processes that are largely internal, such as consciousness and attention. While it may not have all the answers to complex questions about human nature, it provides valuable tools to make sense of our experiences and behaviours.

What is Psychology?

Defining psychology is challenging because the field is constantly evolving. The word psychology comes from two Greek words: psyche (meaning soul) and logos (meaning science or study). Originally, it was the study of the soul or mind.

Today, psychology is formally defined as a science which studies mental processes, experiences and behaviour in different contexts. It uses scientific methods to systematically collect and analyse data to build knowledge.

Let's break down the three key terms in this definition:

Mental Processes

• These refer to states of consciousness or awareness, such as thinking, problem-solving, remembering, and perceiving.
• While mental processes are linked to brain activity (which can be observed with brain imaging techniques), they are not the same thing. The mind does not have a physical location like the brain. Instead, it emerges from our interactions and experiences.
• Psychologists study these processes to understand how the mind works and how we can improve our mental capacities.

Experiences

• Experiences are subjective in nature, meaning they are internal to the person having them. We cannot directly observe someone else's experience; only they can be conscious of it.
• Psychologists study a wide range of experiences, from the pain felt by a terminally ill patient to the positive feelings of a romantic encounter.
• The nature of an experience is influenced by both internal and external conditions.

Behaviours

• Behaviours are our responses, reactions, or activities. They can be simple or complex.
• Overt behaviours are external and can be observed by others (e.g., blinking, running, talking).
• Covert behaviours are internal and cannot be directly seen (e.g., the pounding of your heart during an exam, or your muscles twitching as you think about a move in chess).
• All behaviours are triggered by a stimulus, which can be internal (a thought) or external (seeing a tiger). Some psychologists study behaviour as an association between a stimulus (S) and a response (R).

Psychology as a Discipline

Psychology aims to understand and explain behaviour, experience, and mental processes in a systematic and verifiable way. While everyday common sense often tries to explain behaviour, psychologists work to minimise personal biases in their interpretations.

The discipline has two parallel streams, making it both a natural science and a social science.

Psychology as a Natural Science

• This stream views psychology as a science that uses methods from physics and biology. It has its roots in philosophy but grew into a modern science by applying the scientific method.
• It follows the hypothetico-deductive model, which involves:
  1. Developing a theory to explain a phenomenon.
  2. Forming a testable hypothesis based on the theory.
  3. Gathering empirical data to test the hypothesis.
  4. Revising the theory if the data suggests a different explanation.
• The main goal is to identify cause-and-effect relationships to predict and, if necessary, control behaviour. It assumes that all behaviours have discoverable causes.
• This approach has been influenced by the evolutionary approach from biology to explain phenomena like aggression and attachment.

Psychology as a Social Science

• This stream recognises that psychology studies human beings in their socio-cultural contexts. Humans are not just influenced by their environment; they also create it.
• It focuses on humans as social beings and explains behaviour in terms of the interaction between a person and their socio-cultural context.
• It assumes that behaviour has multiple causes, not just one.

Understanding Mind and Behaviour

For a long time, the concept of the "mind" was considered unscientific because it couldn't be physically located or defined in concrete terms. However, thanks to neuroscientists and physicists, the mind is once again a central topic in psychology.

Is the mind the same as the brain? No. While the mind cannot exist without the brain, it is a separate entity. The brain is a physical structure, but the mind is what emerges from the brain's activities and our interactions with the world.

Evidence for this distinction comes from cases where:

• Patients with damage to the visual part of their brain (occipital lobes) could still respond to visual cues.
• An athlete who lost his arm in an accident continued to feel a "phantom arm" and even tried to use it.
• A young man with a brain injury claimed his parents had been replaced by "duplicates."

In these cases, a part of the brain was damaged, but the person's "mind" and subjective experience remained intact in some form.

Recent studies have shown a clear relationship between the mind and body. A new field called Psychoneuroimmunology emphasizes how the mind can influence the immune system.

Popular Notions about the Discipline of Psychology

Many people act like amateur psychologists, using common sense to explain behaviour. However, these popular theories are often based on hindsight and may not be scientifically accurate.

Psychology, as a science, seeks to identify patterns of behaviour that can be predicted, not just explained after the fact. Scientific psychological knowledge often goes against common sense.

A study by Dweck (1975) challenged the common-sense idea that giving children easy problems builds their confidence.

• Group 1: Given only easy math problems they could always solve.
• Group 2: Given a mix of easy and difficult problems. When they failed, they were told it was because they didn't try hard enough.
• Result: When faced with new, difficult problems, the first group (who had always succeeded) gave up much faster than the second group (who had experienced failure and learned to attribute it to lack of effort).

Evolution of Psychology

Modern psychology has a short history, with its formal beginning traced to 1879, when Wilhelm Wundt established the first experimental laboratory in Leipzig, Germany.

Here are the major schools of thought that have shaped the discipline:

Structuralism

• Led by Wilhelm Wundt, structuralists were interested in the structure of the mind.
• Their primary method was introspection, where individuals were asked to describe their own mental processes and experiences in detail.
• Limitation: Introspection was considered unscientific because reports could not be verified by outside observers.

Functionalism

• Developed by American psychologist William James, who set up a lab in Cambridge, Massachusetts.
• Functionalism focused on what the mind does and how behaviour helps people adapt to their environment.
• Instead of the structure of consciousness, James was interested in consciousness as an "ongoing stream" of mental processes.
• John Dewey, an influential educational thinker, used functionalism to argue that humans seek to function effectively by adapting to their surroundings.

Gestalt Psychology

• Emerged in Germany in the early 20th century as a reaction to structuralism.
• Gestalt psychologists argued that our perceptual experience is more than the sum of its parts. The word Gestalt means "whole."
• They believed that experience is holistic.

Behaviourism

• Around 1910, John Watson rejected the ideas of mind and consciousness as subjects for psychology.
• Influenced by physiologists like Ivan Pavlov, Watson argued that scientific psychology must focus on what is observable and verifiable: behaviour.
• He defined psychology as the study of behaviour or responses to stimuli.
• Behaviourism was further developed by influential psychologists like B.F. Skinner.

Psychoanalysis

• Founded by Sigmund Freud, who viewed human behaviour as a dynamic expression of unconscious desires and conflicts.
• He believed humans are motivated by pleasure-seeking desires, which are often unconscious.
• Psychoanalysis was developed as a system to understand and cure psychological disorders.

Humanistic Perspective

• Humanists like Carl Rogers and Abraham Maslow took a more positive view of human nature.
• They emphasized the free will of human beings and their natural desire to grow and reach their full potential.
• They argued that behaviourism was too mechanistic and undermined human freedom and dignity.

The Cognitive Perspective

• This perspective developed by combining aspects of structuralism and Gestalt psychology.
• Cognition refers to the process of knowing, including thinking, understanding, perceiving, and problem-solving.
• Cognitive psychologists view the human mind as an information-processing system, similar to a computer, that receives, processes, stores, and retrieves information.
• A modern view within this perspective is constructivism, which suggests that humans actively construct their minds through their exploration of the physical and social world. Psychologists like Piaget and Vygotsky were key figures in this area.

Development of Psychology in India

While Indian philosophical traditions have long focused on mental processes, consciousness, and the self, modern psychology in India has been largely dominated by Western developments.

• The modern era began at Calcutta University, where the first psychology laboratory was established in 1915.
• The first Department of Psychology was started at Calcutta University in 1916, followed by a Department of Applied Psychology in 1938.
• Early development was influenced by Dr. N.N. Sengupta, who was trained in Wundt's experimental tradition, and Professor G. Bose, who was trained in Freudian psychoanalysis and established the Indian Psychoanalytical Association in 1922.

Durganand Sinha traced the history of modern psychology in India through four phases:

1. First Phase (until independence): Focused on experimental, psychoanalytic, and psychological testing, reflecting Western trends.
2. Second Phase (until the 1960s): A period of expansion where Indian psychologists tried to link Western psychology to the Indian context.
3. Third Phase (post-1960s): A shift towards problem-oriented research that was relevant to the problems of Indian society.
4. Fourth Phase (late 1970s onwards): A phase of indigenisation, where psychologists stressed the need for a framework that was culturally and socially relevant to India, sometimes drawing from ancient texts and scriptures.

Today, psychology in India is a strong discipline, applied in diverse areas like hospitals, corporate organizations, sports, and the IT industry.

Branches of Psychology

Psychology has many specialized fields. Here are some of the major ones:

• Cognitive Psychology: Investigates mental processes like attention, memory, problem-solving, and language.
• Biological Psychology: Focuses on the relationship between behaviour and the physical system (brain, nervous system, genetics). Neuropsychology is an emerging field within this branch.
• Developmental Psychology: Studies the physical, social, and psychological changes that occur across the life-span, from conception to old age.
• Social Psychology: Explores how people are affected by their social environments and how they think about and influence others. Topics include attitudes, prejudice, and interpersonal attraction.
• Cross-cultural and Cultural Psychology: Examines the role of culture in understanding behaviour, thought, and emotion.
• Environmental Psychology: Studies the interaction of physical factors like temperature, pollution, and natural disasters on human behaviour.
• Health Psychology: Focuses on the role of psychological factors (like stress and anxiety) in the development, prevention, and treatment of illness.
• Clinical and Counselling Psychology: Deals with the causes, treatment, and prevention of psychological disorders (e.g., anxiety, depression). Counselling psychology focuses on improving everyday functioning and dealing with less severe problems.
• Industrial/Organisational (I/O) Psychology: Deals with behaviour in the workplace, focusing on training, work conditions, and employee selection.
• Educational Psychology: Studies how people of all ages learn and helps develop instructional methods and materials.
• Sports Psychology: Applies psychological principles to improve sports performance by enhancing motivation and other factors.

Psychology and Other Disciplines

Psychology is an interdisciplinary field that shares knowledge with many other areas of study.

• Philosophy: Psychology grew out of philosophy, and it still draws from philosophical methods of knowing and ideas about human nature.
• Medicine: Doctors recognize that a "healthy body requires a healthy mind." Psychologists work in hospitals to help patients with health-hazardous behaviours, counselling, and managing illnesses like cancer and AIDS.
• Economics, Political Science, and Sociology: Psychology contributes to understanding consumer behaviour, voting patterns, and the behaviour of individuals within social groups.
• Computer Science: The effort to create artificial intelligence mimics the human mind. Cognitive science is a field where psychology and computer science come together to understand information processing.
• Law and Criminology: Psychology helps the legal system understand topics like witness memory, jury decision-making, and what makes a punishment just.
• Mass Communication: Psychology helps in developing effective communication strategies and understanding the media's influence on attitudes and behaviour.
• Music and Fine Arts: The study of music and emotions is an area where these fields converge. "Music Therapy" is an emerging application.
• Architecture and Engineering: Psychological knowledge helps in designing spaces and mechanical devices that are safe, aesthetically pleasing, and account for human habits.

Psychology in Everyday Life

The knowledge of psychology is not just for academic curiosity; it can be applied to solve a wide range of real-world problems, from personal issues to large-scale social problems like poverty, violence, and environmental degradation. Many psychologists design and implement intervention programs to improve people's quality of life.

On a personal level, understanding psychology can help you:

• Develop a more balanced and positive understanding of yourself.
• Improve your study habits, learning, and memory.
• Use better decision-making strategies to solve personal and interpersonal problems.
• Reduce and manage stress, such as examination stress.

Ultimately, the knowledge of psychology is rewarding from both a personal and a social point of view, helping you understand yourself and others better.
