This is a classic edition of Hugh Wagner's influential overview of the biopsychological underpinnings of human motivation. It includes a new foreword written by Michael Richter who reflects on Wagner's 20 years of teaching, writing and research in the field of biopsychology and promises an engaging, succinct and accessible introductory text that remains relevant and useful to students today.

The Psychobiology of Human Motivation explores what directs our behaviour, from basic physiological needs like hunger and thirst to more complex aspects of social behaviour like altruism. Wagner explores the limits of biological explanations and shows how humans can influence 'basic' physiological drives in order to adapt to a complex social environment.

An accessible, engaging resource strengthened by many applied examples, Wagner's text continues to be integral reading for undergraduate students seeking a solid introduction to the psychology of human motivation across the social and behavioural sciences.
