New Fourth Edition Now Available! Thousands of studies have been published attempting to uncover how the brain works, the functions of different regions of the brain, and how specific parts of the brain contribute to the development of certain disorders. The overwhelming majority of this work has been produced by molecular and behavioral geneticists, neuroscientists, psychologists, and psychiatrists; not by criminologists and certainly not by sociologists. Biosocial Criminology: A Primer exposes undergraduate and graduate students, sociologically trained criminologists, and laypersons alike to biological and genetic concepts and by showing how these concepts can be used not just in biosocial criminological theory and research, but in all criminological research. Now available in a new fourth edition, Biosocial Criminology: A Primer (print or eBook) is fused with an accompanying website that includes concepts, automatically-graded quizzes, glossaries, interactive flash cards, and much more to help students assess comprehension of concepts taught.
