ao3 institutional agg

• Delisi -studied 813 juvenile delinquents confined in institutions in Cali. brought into prison several negative dispositional features such as a history of violent beh, more likely to engage in sexual misconduct, and committed more acts of physical violence -brought to the attention of the parole board compared with a control group of inmates

  when inmates enter prison, they carry in negative traits like agg with them, which leads to further acts of agg in prison rather than agg being caused by the prison

  validating the importation model of institutional aggression
• Dilulio - the administrative control model (ACM) poorly managed prisons are much more likely to lead to agg. Poor management= weak and indecisive leadership; a culture of informal rules and few opportunities for education for inmates→ exacerbate the effects of the agg disposition which brought into prisons and further contribute to agg. If the prison administration is effective, it can have a diminishing effect on the impact of 'brought in' traits.

  by themselves may not cause institutional agg, since these interact with env factors → agg.

  As this is not accounted for by i m, incomplete
• support for the influence of situational variables.

  Cunningham- analysed 35 inmate homicides in Texas prisons and found that motivations for the behaviours were linked to some of the deprivations identified by Clemmer. Particularly important were arguments over personal possessions, drugs, and homosexual relationships.

  This demonstrates that deprivation of goods causes frustration and facilitates competition and use of aggression to acquire them, showing that the prison setting itself leads to aggression.

  Adds validity to the situational explanation of institutional aggression.
• A weakness of the deprivation model is that there is refuting evidence

  The deprivation model predicts that a lack of freedom and heterosexual contact →high levels of agg beh in prisons.

  Hensley- studied 256 male and female inmates of two prisons in Mississippi, allows conjugal visits (that is, visits from partners specifically to have sex).

  no link between involvement in these visits and reduced agg beh.

  Since relieving deprivation does not reduce agg, this raises doubts about whether aggression within prison is truly caused by deprivation in the first place.

  reduced validity
