MEANING AND DEFINITION Psychology owes its origin from Philosophy. In the year 1950, Rudolf Goecklefirst used the word „Psychology‟. The term „Psychology‟ is a combination of twoGreek words „Psyche‟ and „Logus‟ which mean „Soul‟ and „Science‟, respectively.It has a long history. A review of the history of psychology reveals that during theGreek period philosophers dominated the field of psychology. At that time,Psychology was not a separate discipline. It got scientific status in the year 1879,when Wilhelm Wundt established the first psychological laboratory at Leipzig inGermany. It has been defined differently by different philosophers andpsychologists. The most appropriate definition of psychology has been advocatedby R.S. Woodworth (1910-1960). According to him, “Psychology is the scientificstudy of the activities of the organism in relation to its environment”. Psychologyis a positive science which helps to understand, predict and control humanbbehaviour. It uses scientific methods to study different activities and experiencessystematically. The word „activities‟ includes both external behaviours and internalmental processes. It studies behavior of living organisms, both animals and humanbeings. It acknowledges the role of environment in shaping the behavior oforganisms. Thus, it is concluded that psychology is the scientific study of behaviours, experiences and mental processes of the organisms in relation to theenvironment.
