Forensic Psychology Key Words Flashcards
Crime
An act committed in violation of the law where the consequence of conviction by a court is punishment, especially where the punishment is a serious one such as imprisonment
Official statistics
Figures based on the numbers of crimes that are reported and recorded by the police which are often used by the government to inform crime prevention strategies
Victim surveys
A questionnaire that asks a sample of people which crimes have been committed against them over a fixed period of time and whether or not they have been reported to the police
Offender survey
A self-report measure that requires people to record the number and types of crimes they have committed over a specified period
Offender profiling
A behavioural and analytical tool that is intended to help investigators accurately predict and profile the characteristics of unknown criminals
The top-down approach
Profilers start with pre-established typology and work down in order to assign offenders to one of two categories based on witness accounts and evidence from crime scene
Organised approach
An offender who shows evidence of planning, targets the victim and tends to be socially and sexually competent with higher than average intelligence
Disorganised approach
An offender who shows little evidence of planning leaves clues and tends to be socially and sexually incompetent with lower than average intelligence
The bottom-up approach
Profilers work up from evidence collected from the crime scene to develop hypotheses about the likely characteristics, motivations and social background of the offender
Investigative psychology
A form of bottom-up profiling that matches details from the crime scene with statistical analysis of typical offender behaviour patterns based on psychological theory
Geographical profiling
A form of bottom-up profiling based on the principle of spatial consistency that an offender’s operational base and possible future offences are revealed by the geographical location of the previous crimes
Marauder
An offender who operates in close proximity to their home base
Commuter
An offender who is likely to have travelled a distance away from their usual residence
Atavisic form
A biological approach to offending that attributes criminal activity to the fact that offenders are genetic throwbacks or a primitive sub-species ill-suited to conforming to the rules of modern society. Such individuals are distinguishable by particular facial and cranial characteristics
Eugenic
A movement which advocated that the human gene pool could be improved by encouraging reproduction in people with desirable traits and preventing reproduction in those with undesirable traits
