How different are men and women's brains? Does altruism really exist? Are our minds blank slates at birth? And do dreams reveal our unconscious desires? Psychology is everywhere in today's society. No crime fiction, documentary, chat show or medical consultation is complete without the introduction of a psychological angle. Psychology seeks to understand and explain thoughts, feelings and behaviour through a dizzying array of ideas and theories, shedding light on everything from memory, social mobility and attitude formation to delusions of grandeur, alcoholism and computer phobia, to name a few. In 50 Psychology Ideas You Really Need to Know, Professor Adrian Furnham explains the central ideas of psychology in 50 concise and accessible essays. Packed with the latest research, most important case studies and arguments of key thinkers, this book is the perfect introduction to psychological theory.
