Gradual evolution of the term psychology:
1. Etymologically the word ’ Psychology’ has been derived from the two Greek words’ Psyche’ means ‘Soul ’ and ‘Logos’ means ‘science’ or ‘study of’. Thus, the meaning of the word’ Psychology’ is the science of Soul.
Ancient Greece like Aristotle and Plato believed that Psychology is the science of soul. Rudolf
Goeckle used the word psychology for the first time as a separate subject
in 1950. In the beginning Psychology was a branch of Philosophy. Psychology
becomes an independent subject since 16th century. Soul is invisible
and we cannot have direct experience. The soul is an abstract entity and is
beyond our study. Thus, the concept of Psychology as the ‘science of soul’ did
not remain popular and was rejected.
2.
In the 18thcentury
psychology was defined as the science of mind’. Descartes defined psychology as the science of mind. Later on this
too was rejected as the mind itself was equally vague like that of the soul and
it could not determine and objectively study.
3.
Afterwards Psychologists like William James and William
Wundt defined psychology as the science of consciousness. Consciousness
goes to mean immediate awareness of the mind. We are aware of what happens in
the conscious mind. We can report it and study it reliable on the scientific basis.
But even this meaning of Psychology as the science of consciousness was
discarded by Philosophers on the ground that it does not include the sub-conscious
and un-conscious activities of the mind. It was further made known that un-conscious
occupies the larger part of mind to which attention needs to be directed. Sigmund Freud, the father of
un-conscious school of Psychology [father of school psycho-Analysis] rejected
this concept as there are other parts of consciousness like un-consciousness
and sub-consciousness.
4.
From the 19th
century onwards, with the advent of the modern era of scientific
investigation and thought, the Behaviorism Psychologists like J.B Watson, Pillsbury and Mc Dougall began to define Psychology
as the science of the behavior of an organism.
The latest and the modern
concept of psychology is the science of behavior and experience. The term
behavior includes all the activities both internal and external, Cognitive, Conative
and affective aspects of both human and animal. Behavior concerns with all the
segments of human mind-conscious, sub-conscious and un-conscious. Behavior is
an action that can be observed objectively. Thus, Psychology includes all the
behavior of Human beings as well of animals, of Normal as well as Abnormal and
of Children as well as of Adults.
Definitions
of Psychology:
1. According to Pillsbury,” Psychology is the science of human behavior”.
2. Crow and Crow,” Psychology is the study of human behavior and human
relationships”.
