"This extensively revised and enlarged edition is a sequel to the first edition which was received warmly by the students and the teacher community of the country. In its present form it has the distinction of being enriched in terms of the addition of a number of new chapters and topics as well as refinement of the contents of the previous ones for enabling it to meet the present-day requirements of the Psychology syllabi of the CBSE and other Boards of school education. Besides serving the needs of the class XI students belonging to the schools of our country, it has sufficient capacity in its present revised form to provide a basic structure to those who study psychology at the graduation or post graduation stages of their higher education or opt for Psychology as an optional paper for their Indian or provincial civil services and other competitive examinations."
