9. The Radex Model of Serial Killers

About this Lecture

Lecture

In this lecture, we discuss a study of 100 serial killers (Canter et al., 2004), focusing in particular on: (i) how criminal behaviour can be analysed using a model known as a ‘radex’; (ii) how the radex model of serial killing combines representations of differences in quantity and differences in quality to allow researchers to draw conclusions about the salience of particular types of criminal activity.

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.
