Investigative psychology (IP)
Introduction to investigative psychology
Synopsis
a key issue in contributing to all aspects of an investigative process is the identification of the salitent aspects of any given set of criminal actions
the study of offenders and the processes of apprehending them and bringing them to justice
deals with what all those involved in crime and its investigation do, feel and think.
this modelling contributes to central problem-solving processes, which consist of making inferences about subsets of information, such as the characteristics of an offender, from other subsets of information, such as the details of what happens in a crime
