Forensic psychology key terms Flashcards
Offender profiling
A behavioural and analytical tool that is intended to help investigators accurately predict and profile the characteristics of unknown offenders.
The top-down approach
Profilers start with a pre-established typology and work down to lower levels in order to assign offenders to one of two categories based on witness accounts and evidence from the crime scene.
Organised offender
An offender who shows evidence of planning, targets specific victims and tends to be socially and sexually competent with higher than average intelligence.
Disorganised offender
An offender who shows little evidence of planning, leaves clues at the scene and tends to be socially and sexually incompetent. They will usually have lower than average intelligence.
The bottom up approach
Profilers work up from the evidence collected at to crime scene to develop hypothesis about the likely characteristics, motivation and social background of an 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 offenders operational base and possible future offences are revealed by the geographical location of their previous crimes.
Atavistic form
A biological approach of offending that attributes criminal activity to the fact that offenders are genetic throwbacks or a primitive sub species ill suited to conforming with the modern rules of society. Such individuals are distinguishable by particular facial and cranial characteristics.
Genetics
Genes consists of DNA strands. DNA produces ‘instructions’ for general physical features of an organism (eye colour, height) and specific physical features (neurotransmitter levels and size of brain structures). These may impact on psychological features (intelligence and mental disorders). Genes are transmitted from parent to offspring ie inherited.
Neural explanation
Any explanation of behaviour (an its disorders) in terms of (dys)functions of the brain and nervous system. This includes that activity of the brain structures such as the prefrontal cortex , and neurotransmitters such as dopamine and serotonin.
The criminal personality
A feature of Eysenck’s theory of crime, 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.
Level of moral reasoning
Moral reasoning refers to the way a person thinks about right and wrong. It is presumed that such thinking applies to moral behaviour. The higher the level, the more that behaviour is driven by a sense of what is right and the less it is driven by just avoiding punishment or the disapproval of others.
Cognitive distortions
Faulty, biased and irrational ways of thinking that mean we perceive ourselves, other people and the world inaccurately and usually negatively.
Hostile attribution bias
The tendency to judge ambiguous situations, or the actions of others as aggressive and/or threatening when in reality they may not be.
Minimalisation
A type of deception that involves downplaying the significance of an event or emotion. This is a common strategy when dealing with feelings of guilt.
