The question of motivation in psychology is the fundamental problem of why organisms behave. In this book, originally published in 1975, various theoretical approaches – based on biological needs or on the way we perceive ourselves and our environment – are described and discussed, together with their supporting evidence, and the underlying relations between them are made clear.
