SITUATIONAL MODELS
Prison environment.
THE DEPRIVATION MODEL:
day-to-day: inc/ stress - agg/ to
reduce stress + obtain
desired resoucres. Get control
over conditions imposed
Liberty, autonomy, goods and services,
heterosexual relations, security, freedom
Highly frustrating - agg/ reaction -
frustration-agg/ theory (Dollard et al,
1939). Express frustration through
violence towards staff
THE MANAGEMENT MODEL: Poor
leadership, high staff turnover, lack of
discipline. Less likely engage in agg/
beh/ if eff/ management + prisoners
believe in efficacy of
education+treatment programmes
McCorkle et al (1995) - no evidence - correlation
bet/w violence+aspects of prison environment -
sample 371 US prisons. Deprivations=constant
BUT serious outbreaks are not.
Poor management practices, high staff turnover +
lack discipline. Way deprivations managed by staff
more imp/ than deprivations themselves

Model: best explain inmate violence to staff (most restrictive
regimes=highest incidences). Imp/ Model: inmate violence to
others - agg/ gang cultures persist inside

IDA - REAL WORLD APPLICATION -
Situational model: Abu Ghraib prison
atrocities: Iraq prisoners of war subjected
to dehumanising + degrading treatment.
Zimbardo (2007) - prison guard beh/ -
product of situational forces of being a
guard rather than personal
characteristics. Good soldiers to do bad
things "Lucifer Effect"
