3. Defining and Measuring Crime

About this Lecture

Lecture

In this lecture, we think about how crime can be defined and measured, focusing in particular on: (i) how conceptions of criminality may vary between different legal systems or social groups; (ii) some of the issues this creates for defining crime; (iii) different ways of measuring crime and their inherent challenges, including official records, victim surveys and offender self-reports.

Course

In this course, Professor David Canter (University of Liverpool) provides an introduction to the field of forensic psychology and some of the most important practices and areas of research associated with it. In the first lecture, we start with a definition of forensic psychology as a discipline that applies psychological insights to legal processes and the criminal justice system. In the second lecture, we consider the different ways in which psychologists have theorised the causes of crime. In the third lecture, we think about how crime can be defined and measured. Next, we think about offender profiling. In the fifth lecture, we explore how this practice gradually developed into the broader area of investigative psychology. In the sixth lecture, we take a closer look at the field of investigative psychology and how it can contribute to police investigations. In the seventh lecture, we focus on geographical offender profiling. In the eighth lecture, we explore investigative interviewing. In the ninth and final lecture, we explore a specific method for modelling serial murder, known as the ‘radex model’ of serial killers.
