Offender profiling def
A behavioural and analytical tool that is intended to help investigators accurately predict and profile characteristics of unknown criminals
What are the 4 stages of constructing an FBI profile (according to the top-down approach)
Evaluation of the top-down approach
Describe the bottom-up (or British) approach and how investigate psychology fits into this
Describe the assumptions made in investigate psychology
interpersonal coherence (there is a consistency between the way offenders interact with their victims and with others in their everyday lives);
time and place (the time and location of an offender’s crime will communicate something about their own place of residence/employment);
criminal characteristics (characteristics about the offender can help to classify them, which helps the police investigation).

Evaluation of the bottom-up approach
What is an atavistic form (the biological explanation of offender profiling)
A biological approach to offender profiling that explains criminal activity as being a result of poor genetics. It suggests that offenders are a primitive sub-species which may have lacked evolutionary development. This is why they are unable to copy with the demands of a civilised society and inevitably turn to crime.
The approach suggests that offenders can be identified by certain facial features such as curly hair, long ears and glinting eyes.
Describe the Atavistic form as founded by Lombroso
– Lombroso founded the atavistic form which historically moves criminology into a more rigorous and scientific realm and his ideas may have laid the foundation for the modern offender profiling techniques (Top down and bottom up approach)
– Lombroso determined atavistic characteristics that make criminals different from the rest of us – these included murderers having bloodshot eyes, curly hair and long wears – sexual deviants had glinting eyes, swollen fleshy lips and projecting ears – and fraudsters were thin.
– Lambroso’s research: Lambroso examined the facial and cranial features of thousands of Italian conflicts, both living and dead, and proposed that the atavistic form was associated with a number of physical anomalies which are key indicators of criminality. He concluded that 40% of criminal acts could be accounted for by atavistic characteristics. He didn’t use a control group to compare.
What are examples of the atavistic characteristics as suggested by Lambroso
MURDERERS:
- Bloodshot eyes
- Curly hair
- Long ears
SEXUAL DEVIANTS:
- Glinting eyes
- Swollen, fleshy lips
Evaluation of the atavistic form as suggested by Lambroso
– A strength of the atavistic form is its contribution to criminology. He is credited to shift the emphasis of crime research away from a more realistic view toward a more scientific and credible realm. In this way his views have had a major contribution to the science of criminology
- the approach can be seen as racist As there are many racial undertones in atavistic features that Lambroso identified. However, some value can be seen in this limitation as it prevents future repetition of racism in research.
- His ideas that offenders struggle to adjust to society is faulty because immigrants may have similar struggles, yet they do not usually turn to crime.
– There is poor control in Lambroso’s research. Lambroso did not compare his criminal sample with a non-criminal control group. It is possible that, if he had done so, the significant differences in atavistic form that Lambroso reported may have disappeared. Many of the criminals he studied had suffered from a history of psychological and physical disorders which may have altered the findings and these were not taken into account.

Genetic definition
Genes are inherited and they affect DNA. DNA instruct our physical makeup. This includes brain structure, which affects intelligence, thought patterns and other psychological processes.
Describe the genetic explanations for criminal behaviour
TWIN STUDIES:
-Christiansen (1977) studied 87 MZ and 147 DZ pairs and found a concordance in offending behaviour of 33% for MZs and 12% for DZs
CANDIDATE GENES:
- The MAOA Gene controls dopamine and serotonin production. It has been associated with violent crimes
- The CDHI3 Gene has been linked to substance abuse and ADHD.
- Tilhohen et al (2014) did a genetic analysis of 800 offenders and found that 5-10% of all violent crimes in Finland were due to these genes.
DIATHESIS-STRESS MODEL:
- if genetics have an impact on offending, it is likely that this is at least partly influenced by the environment. A tendency towards criminal behaviour may come about through the combination of genetic predisposition and a trigger such as being raised in a dysfunctional environment or having criminal role models.
- Diathesis: Biological factors (e.g. genes, biochemistry), Psychological factors (e.g. Unconscious conflicts)
- Stress: Biological factors (e.g. poor diet, use of drugs), Social factors (e.g trauma), psychological factors (e.g. violation of trust)
Describe the neural explanations for criminal behaviour
PREFRONTAL CORTEX:
- This cortex is associated with emotion and empathy
- Raine et al: reported several brain images of offenders with APD having less developed prefrontal cortexes. There was a 11% reduced grey matter in the prefrontal cortex.
AMYGDALA:
- The most important part of the limbic system for many emotions, including aggression.
MIRROR NEURONS:
- Allow us to have empathy
- Switched on by default
- Keysers et al (2011): found that criminals could only empathise when told to. So people with APD can have empathy, but do so sporadically and by ‘choice’
Neural explanation definition
Any explanation of behaviour (and its disorders) in terms of (dys)function of the brain and nervous system. This includes the activity of brain structures such as the hypothalamus, and brain structures such as serotonin and dopamine

Describe Eysencks’ theory of the criminal personality
THE CRIMINAL PERSONALITY:
- An individual who scores highly on measures of extra version, neuroticism and psychoticism (cannot be easily conditioned, is cold and unfeeling), and is likely to engage in offending behaviour.
BIOLOGICAL BASIS:
- Our personality traits are biological in origin and come about through the type of nervous system we inherit.
- Therefore, all personality types, including the criminal personality type, have an innate biological basis.
- Extraverts have an underactive nervous system (AMYGDALA) which means they constantly seek excitement, stimulation and are likely to engage in risk taking behaviours. They also tend not to condition easily and do not learn from their mistakes.
- Neurotic individuals tend to be nervous, jumpy and over anxious and their general instability means their behaviour is often difficult to predict.
THE ROLE OF SOCIALISATION:
- Criminal behaviour is due to immature development - it is selfish and concerned with immediate gratification, they are impatient and cannot wait for things
- The process of socialisation is one in which children are taught to become more able to delay gratification and more socially orientated
- Eysenck believed that people with high E and N scores had nervous systems that made them difficult to condition.
- As a result, they would learn easily to respond to antisocial impulses with anxiety. Consequently, they would be more likely to act antisocially in situations where the opportunity presented itself.
