6. Which study found that children with variant of the MAOA gene, produced less of MAOA but only showed aggressive behaviour if maltreated during childhood?
Plomin et al.
Brunner et al.
Caspi et al.
Theilgaard
Young et al.
7. Which study found that there was a significant number of adopted individuals with criminal convictions that had biological parents with criminal history?
Hutchings and Mednick
Plomin et al.
Miles and Carey
Coccaro et al.
8. Alternative model to the genetic factors in aggression
Bandura's theory of vicarious reinforcement
Diathesis Stress model
Social learning theory
9. What did Plomin et al find?
There was a significant number of adopted individuals with criminal convictions that had biological parents with criminal history
In a replication of Bandura's bobo doll study there was no difference in MZ and DZ aggressive behaviour
Genetic mutation in mice causes violence
50% variance in aggressive behaviour was due to genetic influence
10. Which study found that male members in a family that showed violent all had a defect MAOA gene and low levels of MAOA produced?
Miles and Carey
Caspi et al.
Brunner et al.
Plomin et al.
11. Issue with genetic factors of aggression in terms of real world application
Provides an excuse for violent crimes, takes away their responsibility for the crime, this causes distress for the victims and their families and friends and is damaging for society as a whole
Mandel said that the theory was monocausal
Must be generalised with caution as its too simplistic
12. Extra Y chromosomes in males leads to...
Increased aggressive behaviour
Increased testosterone levels, which is associated with aggressive behaviour
Low testosterone levels which reduces aggressive behaviour
13. What did Miles and Carey find?
50% of variation in aggressive behaviour was due to genetic influence
In a replication of Bandura's bobo doll study there was no difference in MZ and DZ aggressive behaviour
There was a significant number of adopted individuals with criminal convictions that had biological parents with criminal history
Genetic mutation in mice caused violence in the mice
