Aggression
Genetic factors
-
-
Evaluation:
:red_cross: Nearly all research to support genetic factors was done on animals (Lagerspetz)
:red_cross: Potential issues regarding how aggressive behaviour can be measured
:red_cross: Reductionist/ignores the role of the environment and heart behaviour
MAOA gene
Determines the production of the MAOA
enzyme, which metabolises neurotransmitters
in the brain after an electrical impulse
-
Han Brunner et al found 28 dutch males
who were in evolved in violent, aggressive
behaviour all had low activity of the MAOA gene
-
Evaluation:
:check: Animal studies on mice by
Cases et al found a link to support
:red_cross: MAOA gene cannot account
for all cases of aggression as it is rarely
expressed in women
Media influences

Disinhibition
Most people = violence/aggression is antisocial and harmful and have restraints to prevent the use to resolve conflict
Disinhibition = restraints are loosened, aggressive behaviour becomes normative, socially acceptable and justified
Berkowitz + Alioto = participants who saw a
film showing aggression as revenge and
justified, gave more electric shows for
longer to a confederate
Cognitive priming
Violent images provide us with
ready made scripts about aggression
which are stored and triggered by cues
-
Fischer et al = after being shown aggressive
and derogatory song lyrics about women, more
negative qualities and aggressive behaviour
was shown towards women (the same was
repeated with female participants
