First published in 1943 Crime and Psychology reveals to the public some of the results of well-known magistrate Claud Mullin’s many years of pioneering work in using the help of medical psychologists for the treatment of criminals. The book contains numerous actual cases of real scientific and social value. They show how even men who have in the past been sent to prison for serious offences can be helped, through treatment while at liberty, to lead useful lives for many years afterwards. The author also shows how psychological principles could become essential features of our system of criminal trial. This constructive and convincing book is an essential read for scholars and researchers of criminal psychology, applied psychology, criminology, and psychology in general.
