Schemata are used to organize knowledge, helping people interpret their environment and decide on courses of action. It was hypothesized that officers socialized before the policy change would have schemata that discouraged them from making arrests and rating victims cooperative and likely to prosecute their cases, whereas the opposite was predicted for officers socialized during the pro-arrest era. Using logistic regression, the study analyzed the relationship of officers' schemata to their arrest decisions at domestic calls and their attitudes toward the victims at those calls. There was more similarity than differences between the two groups of officers, although the schema variable did predict officers' belief in the likelihood of victims prosecuting their cases, pointing to the utility of schema theory for understanding police attitudes.
