Forensic Psychology Flashcards
Who proposed the atavistic theory to offending
Cesare Lombroso
Outline the atavistic theory to offending
Criminals have different characteristics to non criminals
Including sloping brows and prominent jaws.
Criminals can be classified in different subtypes of characteristics. Murders have curly hair
Why does the atavistic theory state criminals have different characteristics to non criminals
Lombroso stated this was due to a more primitive stage in evolution
Who proposed the somatotype theory of offending
William Sheldon
Name the three somatotypes and their corresponding characteristics
Endomorphs are fat and soft they are social
Ectomorphs are thin and fragile they have low self esteem
Mesomorphs are criminals. They are aggressive, callous and uncaring of others feelings
Outline a study which investigated the somatotype theory to offending
Sheldon compared male delinquents and college students using a rating scale out of 7. Rating given according to body type and average taken.
Sheldon found that delinquents were significantly more mesomorphic with an average 5.4 rating.
What conclusions can be drawn from Sheldon’s comparative study of delinquents and non-delinquents
Theory that “mesomorphic individuals are more prone to aggressive and criminal behaviour” is supported.
What are the two physiological theories of offending
Atavistic and somatotype theory
Criticisms of Lombroso’s theory
- didn’t compare criminals to non criminals
- sample consisted of individuals with psychological disorders
- Goring’s study comparing criminals and non criminals found no significant difference in the physical features
Strengths of Lombroso’s theory
Moved explanation of criminality into scientific realm and away from wickedness
Criticisms of Sheldon’s theory
- Cortes and Gatti argued his classification of the somatotypes was unreliable
- Sutherland: sheldon failed to use the legal criteria for defining delinquents
When study repeated using legal definition, association between delinquency and mesomorphic body type was no longer present
Other explanations for a link between mesomorphic body type and delinquency
- mesomorphs learn from early the only way to get what they want is to behave in an aggressive manner
- muscular body types attractive to gang members as they are perceived to be more successful at crime
Strength of Sheldons theory
More scientific explanation
Why are twin studies used in explaining criminal behaviour
If one monozygotic twin displays aggressive and criminal behaviour as well as the other twin, then that behaviour must be genetic/innate
Outline Lange findings
Monozygotic twins showed a much higher degree of concordance that dizygotic twins for criminal behaviour
