Currently, psychology has emerged as one of the most promising and demanding subjects across the globe because people today are highly aspirational and always striving to remain at the top in every competitive field, whether business, employment, education, parenting, or social life. In this race to be recognised and successful, many individuals easily fall under the trap of anxiety, stress, frustration, depression, and burnout and struggle with other psychological challenges. This modern lifestyle has significantly contributed to the growing need, value, and importance of psychology.
However, the status of psychology was not always the same. There was a time when psychology was considered a subject of secondary value, even stereotypically labelled as “a subject for girls”. When I enrolled in M.A. Clinical Psychology in 2001, there were only four students out of forty, mainly because the general public was unfamiliar with the true meaning, purpose, and career opportunities of psychology. Even though I chose the subject accidentally, I gradually realised its immense value, relevance, and demand in real life.
Origin of World Psychology
The term "psychology" was derived from the Greek-based Latin word "psychiologia", which was first coined by Croatian humanist Marko Marulić in his book Psichiologia, and he defined psychology as the study of the human soul. As scientific research progressed, psychologists realised that consciousness alone cannot be the sole focus because it cannot be directly observed or measured. Therefore, broader and more scientifically measurable components were added. Modern sources describe psychology as the science of mind, mental life, behaviour, and conscious experience, and the meaning continued to change with time.
Definition of Psychology
The widely and worldly accepted definition of psychology is “the scientific study of the mind, behaviour, and mental processes.” In a nutshell, it explains how and why people think, feel, and act the way they do.

Behaviour Scope of Psychology
Psychology is a broad field that includes human behaviour, mental processes, emotions, personality, and social interactions. As psychological knowledge expanded, it began to be applied in many professional and practical areas. Based on its application and specialisation, the scope of psychology covers the following major branches:
1. Clinical Psychology
Clinical psychology deals with the assessment, diagnosis, and treatment of mental disorders and emotional difficulties. A professional in this field works with people suffering from anxiety, depression, trauma, personality disorders, and other psychological concerns.
2. Counselling Psychology

A professional in this field helps an individual struggling with relationship issues, career confusion, personal crises, low self-esteem, and emotional struggles, guiding them towards better coping and decision-making.
3. Educational Psychology
Educational psychology deals with psychological principles in teaching and learning settings. Educational counsellors help a student in identifying learning styles, aptitude, intelligence, and career interests and guide them in selecting suitable subjects and academic pathways.
4. Industrial/Organizational Psychology
It is applied in organisational and workplace environments. This deals with employee motivation, leadership, job satisfaction, training programmes, performance management, workplace stress, and organisational culture. It plays an important role in Human Resources (HR) and is considered a highly rewarding white-collar career.
5. Social Psychology
Social psychology focuses on how individuals think, behave, and interact in groups or society.
Professionals may work with NGOs, welfare institutions, or research foundations, focusing on topics such as attitudes, prejudice, discrimination, social influence, cooperation, and social development to improve community living standards.
