something that was once defined as crime might not be considered a crime any more. (VICE VERSA)
2 of 58

3 of 58
Age is an issue because...
when do we class someone to have a full understanding of whether their behaviour is criminal.
4 of 58

Official statistics, victim survey and offender self-report.
6 of 58
Keywords for official statistics.
Reported, Recorded, 'dark figure', '25%', police recording rules.
7 of 58

British Crime Survey, 2 years, 16 - 24 years old, randomly selected.
9 of 58

12 of 58

14 of 58
Disorganised offender crime scene characteristics.
Little evidence of plan, victim is known, leaves evidence, body left in open view.
15 of 58
Disorganised offender likely personality and behaviour.
Below-average IQ, unskilled employment, lives alone and close to the scene.
16 of 58
What did Douglas suggest for the typology approach?
A 'mixed' category to accomodate for offenders in between both categories.
17 of 58

Keywords of the geographical approach.
Mental schema, location, MARAUDERS, COMMUTERS.

21 of 58
Name the two early biological explanations of theories of offending.
Lombroso's Atavistic Form, and Sheldon's Somatotype theory.
22 of 58
Lombroso's theory suggests
1. primitive form - not evolved like rest of society. 2. distinctive physical qualities - criminals BORN not made. 3. large jaw, narrow sloping brow, large ears.
23 of 58
Sheldon's somatotype theory suggests
crime based on body shape - mesomorphs (mix of somatotypes) were offenders.
24 of 58
Keywords of Sheldon's research.
200 deliquent photos, 200 control, scale 1-7, rated.
25 of 58
Name the four modern biological explanations.
Genetic Transmission, Chromosomes, Neurophysiology and Eysenck.
26 of 58
Keywords of Genetic Transmission.

27 of 58
What percentage of adoptees with biological convict parents but raised by non-criminal parents had convictions?
20%.
28 of 58
Keywords of Chromosomes.
Jacobs et al, XYY = convicts, unreliable, no longer accepted.
29 of 58
Keywords of Neurophysiology.
Antisocial Personality Disorder, abnormal EEG patterns.
30 of 58
What does Eysenck propose?
Offending behaviour is not directly inherited, but is a consequence of the type of Nervous System we inherit which determines our personality.
31 of 58
What did Eysenck create?
Eysenck Personality Inventory (EPI).
32 of 58
Explain the EPI.
yes/no questions, reveals scores on E (extraversion), N (neuroticism) and P (psychoticism).

are emotionally unstable and anxious - UNPREDICTABLE.
36 of 58
Who supports Eysenck's theory?
McGurk and McDougall.
37 of 58

Inadequate superego, maternal deprivation and Defence Mechanisms.
38 of 58
Keywords of inadequate superego.
WEAK - no identification and no moral code. DEVIANT - identifies but with immoral parent. OVER-HARSH - misbehaves to fulfil unconscious desire for punishment and guilt.
39 of 58
Keywords of maternal deprivation.
attachment broken down - therefore delinquent, emotionless psychopathy.
40 of 58
Keywords of defence mechanisms.
DENIAL, RATIONALISM, DISPLACEMENT.
41 of 58
Keywords for the Social Learning explanation.
OBSERVATION, IMITATION, VICARIOUS REINFORCEMENT. Differential Association Theory - values of associated peers adopted.
42 of 58
Name the study to support Social Learning explanation.
