MAOA evaluation Flashcards
Who studied the male members of a Dutch family?
Brunner et al (1993)
What did researchers find about the men in the dutch family?
- abnormally low levels of MAOA in brains
- Posessed the MAOA-L gene
What did the lab experiments find?
when provoked, MAOA-L ppts displayed higher levels of aggression compared to ppts without this gene variant
What was aggression operationalised as in the lab experiments
forcing a fictional participant to eat an unpleasant hot and spicy sauce
who conducted the meta analysis
vassos (2014)
What did vassos find in the meta analysis
there was no single gene associated with aggression
What did vassos claim in his meta analysis
hundreds of thousands of genes are likely interacting in very complex ways to determine aggression
What did caspi et als research show
genes are not the cause of aggression but act in conjunction with experiences
5 evaluation points
