Models for Understanding Inmate Aggression in Prisons

The Importation Model of Inmate Aggression

The importation model, developed by John Irwin and Donald Cressey in 1962, offers a dispositional explanation for inmate aggression, suggesting that the violent behaviors observed in prisons are often a continuation of the inmates' pre-incarceration lifestyles and behaviors. According to this model, inmates carry into the prison environment their personal histories and characteristics, including their social norms, behaviors, and personality traits. These factors, which are shaped by experiences and associations outside of prison, are believed to significantly influence how inmates interact within the correctional system and contribute to the prevalence of aggressive acts.

Dispositional Versus Situational Explanations in Psychology

Dispositional explanations in psychology attribute an individual's behavior to their inherent qualities, such as personality traits, attitudes, and values. The importation model is a prime example of a dispositional explanation, positing that the aggressive behaviors of inmates are rooted in their personal characteristics and past experiences rather than being solely a product of the prison environment. This contrasts with situational explanations, which argue that behavior is largely determined by external factors, including the immediate environment and social context.

Manifestations of the Importation Model in Prisons

The importation model is evidenced by various risk factors that are indicative of an inmate's likelihood to engage in aggressive behavior. These risk factors include a history of violence, involvement in criminal subcultures, gang affiliations, and substance abuse problems. The model suggests that these pre-incarceration behaviors and affiliations are 'imported' into the prison setting, where they continue to influence the inmate's behavior, potentially leading to conflicts and violence within the prison population.

Empirical Evidence for the Importation Model

Empirical research has provided mixed support for the importation model. Studies have found that certain pre-incarceration factors, such as substance abuse history and demographic characteristics like age and ethnicity, are associated with increased aggression in prison, lending support to the importation model. However, other research has indicated that the relationship between certain factors, such as gang membership, and prison violence may not be as strong as previously thought, suggesting that the importation model may not fully explain the complexity of inmate aggression.

Critiques of the Importation Model

The importation model has been critiqued for its potential oversimplification of the causes of inmate aggression and its primary focus on male prisoners, which may limit its applicability to female inmates and other diverse prison populations. Critics argue that by focusing predominantly on pre-incarceration characteristics, the model may neglect the impact of the prison environment itself on inmate behavior. Additionally, the reliance on correlational data in supporting the importation model means that causation cannot be definitively established, and other factors may also play a significant role in shaping inmate aggression.

The Deprivation Model as a Situational Explanation

In contrast to the importation model, the deprivation model, as articulated by Gresham Sykes in 1958, emphasizes the situational factors of the prison environment as the primary catalysts for inmate aggression. This model argues that the deprivations experienced by inmates, such as the loss of freedom, autonomy, and access to goods and services, create a stressful environment that can lead to frustration and aggression. The deprivation model highlights the importance of the conditions of imprisonment in understanding inmate behavior, offering a situational perspective that complements the dispositional focus of the importation model.

Integrating the Importation and Deprivation Models

In summary, the importation and deprivation models provide two distinct frameworks for understanding the origins of aggression in prison settings. The importation model underscores the influence of an inmate's background and personal history, while the deprivation model focuses on the stressful and punitive conditions of imprisonment. Both models are valuable in that they highlight different aspects of the complex phenomenon of inmate aggression. A comprehensive approach to understanding and addressing prison violence must consider the interplay between dispositional and situational factors, recognizing that both individual characteristics and environmental conditions contribute to the behaviors observed within correctional institutions.
