This revision guide provides concise coverage of the central topics within Biological Psychology, presented within a framework designed to help you focus on assessment and exams, and matching the requirements of the BPS. The text is organised so that the basic principles are outlined first and then expanded upon with a consideration of higher order functions. Revision of the basic principles from the early chapters is revisited in later chapters in the context of higher order psychological functioning. Sample questions, assessment advice and exam tips drive the organisation within chapters so you are able to grasp and marshal your thoughts towards revision of the main topics. Features focused on critical thinking, practical applications and key research will offer additional pointers for you in your revision process/exam preparation. A companion website provides supporting resources for self testing, exam practice, answers to questions in the book, and links to further resources.
