Atavistic Explanation
Lombroso (1876) crims = separate species between mod & prim humans - physical shape of head & face determine born criminal
A03 Supporting Lombroso
examined 383 dead skulls of crime contrib to criminology moved from moralistic to scientific noted facial features - heavy brow large strong jaw large ears extra fingers / toes
skulls could have included ppl w/ learning difs - may skew measurements some have physical effects on facial features
Hooton (1939)
12 yr study 10 US states w/ console of 3023 comp male prisoners 13873 argued crime behav due to bio inferiority & degeneration list of physical features indicated trim behav - sloping head, protruding, narrow jaw - rectifies no L control
Goring (1913)
looked at facial features of 3000 crims & non crims & found no evidence for facial features - L didn’t use control
Kaplan (1980)
states poor appearance linked w/ poor soc interactions (due to how look?) can bring about trim behav, poor self esteem & reluctance to conform
Genetic Explanation
specific genes for crime = candidate genes
Brunner et al (1993) analysis of Neths crime fam had genetic condition Brunner’s Syndrome = low IQ & MAOA deficiency - metabol of S (aggression) can inherit conditions that make prone to crime
Tiihonen et al (2014)
found abs in 2 genes assoc w/ violent crime = MAOA gene controls DA & S & CDH13 linked to substance abuse & attention deficit disorder
diathesis stress model genetics may effect but = triggered by environ
Crowe (1972)
adoptees bio mum w/ crib rec Vs control w/o found of bio mum had rec then 50% of children did by 18 control = 5% regardless of environ = bio predis
Christiansen (1977)
examined 3500 twin pairs in Denmark indicated degree of inheri concor = low even in MZ environ = role dif M&F twins q’s gender role
Male MZ = 35% DZ 13%
Female MZ = 21% DZ = 8% can help rule out environ
Raine (1993)
m-a 13 studies MZ = 52% DZ = 21%
Mednick (1984)
14k adoptees cram recs comp w/ bio & a p’s 13% of a p’s had rec 20% didn’t but bio p’s did 24% = both
Evaluation of Genetic Explanation
twin & fam studies don’t rule out environ - SL - adopt rectify brought up in dif environ helps see genetic effects - adopted child syndrome - bonding and attachment disorders - lying, stealing, defiance of auth and violence
