Forensic Psychology Flashcards
What is meant by 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.
What is meant by 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.
What is meant by Victim survey (or victimisation survey)
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.
What is meant by Offender survey
A self-report measure that requires people to record the number and types of crime they have committed over a specified period.
What is meant by Offender profiling
Also known as ‘criminal profiling’, a behavioural and analytical tool that is intended to help investigators accurately predict and profile the characteristics of unknown criminals.
What is meant by The top-down approach
Profilers start with a pre-established typology and work down in order to assign offenders to one of two categories based on witness accounts and evidence from the crime scene.
What is meant by Organised offender
An offender who shows evidence of planning, targets the victim and tends to be socially and sexually competent with higher than average intelligence.
What is meant by Disorganised offender
An offender who shows little evidence of planning, leaves clues and tends to be socially and sexually incompetent with lower than average intelligence.
What is meant by The bottoms-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.
What is meant by 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.
What is meant by Geographical profiling
A form of bottom-up profiling based on the principle of spatial consistency: than an offender’s operational base and possible future offences are revealed by the geographical location of their previous crimes.
What is meant by Atavistic 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.
What is meant by Genetics
Genes consist of DNA strands. DNA produces ‘instructions’ for general physical features of an organism (such as eye colour, height) and also specific physical features (such as neurotransmitter levels and size of brain structures). These may impact on psychological features (such as intelligence and mental disorder). Genes are transmitted from parent to offspring, i.e. inherited.
What is meant by Neural explanation
Any explanation of behaviour (and its disorders) in terms of (dys)functions of the brain and nervous system. This includes the activity of brain structures such as the hypothalamus, and neurotransmitters such as serotonin and dopamine.
What is meant by The criminal personality
An individual who scores highly on measures of extraversion, neuroticism and psychoticism and cannot easily be conditioned, is cold and unfeeling, and is likely to engage in offending behaviour.
