In psychology, biological psychology or psychobiology is the application of the principles of biology to the study of mental processes and behaviour. A psychobiologist, for instance, may compare the imprinting behaviour in goslings to the early attachment behaviour in human infants and construct theory around these two phenomena. Biological psychologists may often be interested in measuring some biological variable, e.g. an anatomical, physiological, or genetic variable, in an attempt to relate it quantitatively or qualitatively to a psychological or behavioural variable, and thus contribute to evidence based practice. Biopsychology is another synonym for biological psychology. This book presents new and important research from around the globe.
