This book grew out of my experiences and teaching of Psychology. Through observing many classrooms as a teacher trainer and evaluator and from my own success experiences author got the inspiration to write this book. This book is the necessity elementary in nature, being written for students who are studying psychology for the first time.It is scientifically sound and can give a strong foundation for more advanced study.They incite arouse and move to action when they are associated with certain stimuli which signal their presence. This book contains chapters as memory,knowledge,thinking,problem-representation- understanding & learning, creativity & transfer of learning. I hope at least some of our teachers develop a keen interest in stimulating subject and will do independent study,going in the end for beyond the scope and depth of this book; I have drawn the illustrations, pictures, diagrams and examples used in this book from daily life. An effort has been made to keep them simple, useful and similar to situations that every teacher will meet in their day to day work. From the point of view of language,the author has tried to make use of the technical vocabulary at the minimum.
