Indv Diff And Dvt Flashcards
When it is assumed there are no indv duff
Brain damage affected by indv diff eg gage inv both prefrontal corticies damage so defect in rational decision and process of emo= sudden change in high agg
However Phineas gages findings
Unique and not gen to others
Indv diff no effect on brain structure and function
More SIM than diff in 🧠 struc and func so predictable
Eg effect of heroin on synoptic transm as it relieves pain and releases endorphins causing euphoria
Mode of action same for all, so damage same and one case study of drug addict explain neurobiological eff of drugs on all addicts
No indv diff betw agg ppl
Agg caused by same brain dysfunction ie raine found diff in prefrontal and amygdala amongst violent and control so brain func w each group same so diff predictable and damm not affected by indv diff
Frueds view
Childhood exp= indv diff in adult personality
Superego overdvt= seek justice agg as overly moralistic and judgemental
Overdvt id= selfish and demanding personality
Dvt
Childhood exp affecting latter eg social and cig skills
Evolution
I survival of fittest, gen mutations cause adv gene and likely to be passed next gen = exp DVT of human species over gen
Ev evidence
Agg help gain power eg Chester correlation betw sg g and maoa gene in females astd w survival so in ns gene passed down so agg shaped by me and ev adv explains prevalence in society
Hormones
Affect how we develop eg testosterone= male features muscle strength, facial hair, deep voice, more agg
Cortisol= protect against stress and inhibit agg
Hormones evidence
Virkkunen low lev cortisol in violent offenders so not able to control agg= DVT violent behaviour
Dabs= t in saliva 692 male prisoners, high lev in violent offenders than in burglars w same effects in women so DVT of violent behaviours via high t
