Psychology is defined as the scientific study of the mind and behavior. It involves observing mental processes, comparing them, classifying them, and using experiments to test and explain phenomena. Psychology seeks to understand cognition, emotions, and actions that make up human behavior. It aims to discover laws of the mind through scientific methods such as observation, experimentation, and comparison.

 If there were no subject and object, there
would be no experience.
 For example Fear or anger is an
experience.Trembling or striking is a
behavior.

10. Psychology among Sciences
 There are sciences of matter, life and mind.
 Physical sciences
 Physics deals with heat, light, electricity
 Chemistry deals with chemical combinations
of elements.
 Astronomy deals with the heavenly bodies.

11. Biological sciences
 Botany deals with the phenomena of plant
life.
 Zoology deals with the phenomena of animal
life.
 Physiology deals with the functions of the
animal and human bodies.

12. The Nature of Science
A science is a systematic body of
knowledge relating to a certain subject.
It deals with a particular department of
phenomena.
 Physical sciences study the nature of physical
systems.
 Biological sciences study the nature of living
systems.

13. Psychological science
studies the nature of mental
processes and behavior.

14. observation,
 experiment,
 comparison
and classification
as methods of investigation of its
data
A science adopts
In descriptive
sciences,
there is
observation
with
classification.
In
experimental
sciences,
observation is
supplemented
by
experiment.

15. Psychology
observes mental
processes, compares
them with one
another
and groups them
under different
classes.
. It also makes use
of experiments
with the help of
instruments
