2. What is Psychology
Philosophy is the study of the fundamental nature
of knowledge, reality, and existence, especially

theory or attitude that acts as a guiding principle for
behaviour.

of behavior and mental process. From the word
behavior one can extract two meaning, because

behavior.
3. History & Origin of Psychology

status the historical development in psychology
may be classified as
a. The Early Age of Pre Scientific Psychology.
b. The Medieval Age of Scientific Psychology.
c. The Present Age of Contemporary Psychology.
4. The Early Age of Pre Scientific
Psychology.
The earlier attempts for explaining the cause and form
of human behavior were based on superstitions and
movement of stars.
Contributions of Greek Philosophers:
a. Socrates: created a question-answer method to
understand behavior.
b. Plato: created distinction between mind and body.
c. Aristotle: said that mind controls activities of body.
d. Hippocrates: Opposed the role of supernatural
powers in psychology.
5. The Early Age of Pre Scientific
Psychology.
17th Centaury during Roman Empire again
superstitions came up. In addition some theories such
as;
a. Dualism: It says that mind and body are separate
entities. Body is a machine which is controlled by
mind a free bird.
b. Critical Empiricism: It propagates that behavior is the
by-product of two sources such as the things
(external) and mind.
c. Naturalism: It insists the role of feelings and emotions
for studying behavior.

thought/school of psychology to understand behaviour

7. The Medieval Age of Scientific
Psychology.
Structuralism: Psychology is the science of
consciousness or experience. The experience
depends on three elements such as physical
sensation (what he see), feelings (his likes and
dislikes) and images (past memory). Eg. Banana. It
emphasize on systematic study of one’s
mind/consciousness to understand behavior.
Functionalism: It advocates that one’s mind is
constantly weaving associations, revising experiences
for adding to one’s own functional abilities to adapt to
his environment. Eg. Formation of different habits for
adaptation to a situation.
8. The Medieval Age of Scientific
Psychology.
Behaviorism: It says that in addition to consciousness
other factors also influence behavior such as soul,
mind, mental life images, ideas, past experiences etc.
It focus on overt/observable behavior totally.
Gestalt Psychology: It emphasizes on perceiving
things as whole by an individual rather than mere
parts. Human behavior is not a simple stimulus-
response reaction. It is an intelligent behavior which

some concepts;

and unconscious behavior (desire, feeling, drives
and motives).

psychoanalysis). Conscious behavior is
observable.

Ego and Superego. (hypothetical structure)

period: Oral, Anal, Phallic, Latent and Genital
Stage.

stages such as Individual psychology (replaced
sex with power motive) and Analytical Psychology
(replaced sex with social urge or life urge).
11. The Present Age of Contemporary
Psychology.
The present age of psychology still considers the
concepts of Behaviorism and Psychoanalysis as the
main forces of human behavior. Some new concepts
were also propagated during this periods such as
Humanistic Psychology (1950). It emphasized the
individuals' unique potential for psychological growth.
Human beings are purposeful being having capacity to
adapt to any situation. It talks about self determination,
free will, self actualization, and choice of human
behavior. Carl Rogers who developed Client centered
therapy and Abraham Maslow who explained the
concept of need hierarchy which became founder
12. The Present Age of Contemporary
Psychology.

hierarchy theory. It focuses on study of personal
experiences that seem to transcend (beyond the range
of limits ) ordinary existence. This can be explained in

16. Psychology as a Science ?

of the experience and behaviour. However
experience cannot be adequately explained without

muscles are organs of the body. So mental
processes are closely related to bodily processes.

customs and institutions of a society in all its stages of

speciality. It concentrates on diagnosis and treatment
mental illness. These diagnosis and treatments are set
