Psychology is both an applied and academic field that studies the human mental processes and behaviour. The present book comprehensively deals with the appropriate areas of Psychology to help the students of Nursing and other healthcare courses gain an insight of the subject. The text begins with the evolution and history of Psychology and its branches, and moves on to the methods adopted by the contemporary psychologists in mapping the human brain. It focuses on the applications of psychology in performance enhancement and self-help. Psychological aspects like perception, learning, emotion, aptitude and intelligence are further exemplified and elucidated in this book with the clinical problems associated with them. The book also deals with the common health problems associated with stress—the bane of modern existence—and provides solutions to cope with those problems. The modern day issues like lifestyle illness and attitudinal problems are also addressed in this book. In the second edition, a new chapter namely, ‘Importance and Impact of Psychology for Nursing Profession’ has been introduced, which facilitates the nurses to adapt to the changing demand of the profession seamlessly. Furthermore, in this edition, the narrative has been revised in general with added commentary and pictorial representations to make the text illustrative and engaging.
