Biological Flashcards
The Effects of Drugs on Neutransmission
Olds and Milner (1954) (support) - Mice endured pain in order to recieve “reward brain pathway” stimulation (therefore pleasure over pain)
Jones and Stones (1990) (rejects) - Gave cannabis users marijuana or placebo and found NO difference in effect
Evolution
Daly and Watson (1988) (support) - Over time men have developed mate retention to keep hold of partners (abuse)
Aggression (brain structure)
Charles Whitman (support) - Tumour pressing on amygdala, killed a few blokes
Raine (support) - Lower activity in amaygdala and PFC in murderers
Aggression (Neurotransmitters + Hormones)
Ferrari (2003) (support) (serotonin and dopamine) - rats anticipated fight, dopamine increased and serotonin decreased
Wagner (1979) (support) (testosterone) - Rats not aggressive when balls cut off, but were when injected with testosterone
Barazman (2013) (support) (cortisol) - cortisol correlated with aggressive acts after waking up
Psychodynamic theory
Hoffman (1977) (reject) - Females make up small percentage of criminals, therefore can’t have inherently weaker superegos
General supports - high application as it moved away from barbaic treatments and high validity due to case studies
General weaknesses - low generalisability and validity due to case studies, and low reliability due to unscientific concepts
Individual, developmental and evolutionary differences in aggression
Freud weak / harsh superego
