Psychology unit 3 aggression revision
Explanations into institutional aggression- deprivation model
Aggression in prisons is caused by frustration at the loss of liberty (freedom),
autonomy (independence), goods and services, heterosexual relationships and
security. Aggression may also be used to try and recover these things.
/ Light- found that 25% of assaults had no relation to the aggressive
behaviour. Therefore 75% of assaults were related to aggression.
Therefore deprivation can account for some prison violence but there are
other reasons for violence too.
prison violence is not constant, but can erupt suddenly. If deprivation is
constant then violence should be too.
overcrowding doesn't always lead to more violence. This undermines the
theory as overcrowding should cause more deprivation and so more
/ Richards found that the type of inmate program affected the amount
of violence. This shows that situational variables affect aggression although
deprivation itself isn't really studied.
/ Wilson set up 2 units in a prison for violent prisoners. These units had
cells with windows and were less claustrophobic, more comfortable
temperatures, and everyday prison sounds were blocked out by music from
a radio. These changes eliminated assaults on prison staff and other inmates.
This supports deprivation as it shows that when people were undeprived
their violence dropped. Therefore deprivation increases violence.
