The fascinating and rapidly growing field of biological psychology-also widely known as biopsychology, behavioural neuroscience, or psychobiology-is concerned with the relationship between brain and behaviour. Broadly speaking, biological psychologists seek to understand dizzyingly difficult questions about how biological processes underlie normal (and abnormal) behaviour and other psychological states and processes. As research in and around biological psychology burgeons as never before, this new four-volume collection from Routledge's acclaimed Critical Concepts in Psychology series meets the need for an authoritative reference work to make sense of a rapidly growing and ever more complex corpus of literature. Edited by two leading scholars, the collection gathers foundational and canonical work, together with innovative and cutting-edge applications and interventions. With a full index, together with a comprehensive introduction, newly written by the editors, which places the collected material in its historical and intellectual context, Biological Psychology is an essential work of reference. The collection will be particularly useful as an essential database allowing scattered and often fugitive material to be easily located. It will also be welcomed as a crucial tool permitting rapid access to less familiar-and sometimes overlooked-texts. For researchers and advanced students, it is a vital one-stop research and pedagogic resource.
