Let’s begin the fascinating journey into the science of the human mind
and behaviour.
1. Introduction
Psychology is the scientific study of behaviour and mental processes. It
helps us understand how people think, feel, and behave in different
situations.
The term psychology comes from two Greek words:
Psyche – soul or mind
Logos – study
Earlier psychology meant study of the soul, but today it studies behaviour
and mental processes scientifically.
Behaviour includes all actions that can be observed such as talking,
walking, or studying.
Mental processes include internal experiences such as thinking,
remembering, feeling, and imagining.
Psychology helps explain:
Why people behave differently
How people learn
How emotions and thinking affect behaviour
2. Nature of Psychology
Psychology as a Discipline
A discipline is an organized body of knowledge.
Psychology is a discipline because:
, It uses systematic study and research
It has theories, principles, and methods
It studies behaviour scientifically
Psychologists collect data using:
Observation
Experiments
Surveys
Case studies
Psychology as a Natural Science
Natural sciences study physical and biological processes using scientific
methods.
Psychology is similar to natural sciences because:
It studies brain and nervous system
It uses experiments and measurements
It studies biological aspects of behaviour
Example:
How the brain controls emotions
How hormones affect behaviour
Psychology as a Social Science
Social sciences study human behaviour in society.
Psychology is also a social science because it studies:
Social interactions
Culture
Relationships
Social influence
Example:
Why people follow group behaviour
How culture affects personality
Thus psychology combines natural science and social science approaches.
