This study was concerned with determining the attitudes that prisoners and guards at Indiana State Prison hold toward one another, and with examining the interactions between prisoners and guards. Data were collected by means of structured interviews with 25 prisoners and 25 guards. Perceptions of each group were reported for the following areas: characteristics of members of the other group, frequency of interaction between the two groups, type of interactions, degree of freedom for interaction, length of interaction, and type of verbal patterns used when speaking to members of the other group. Also noted were the way in which prisoners speak about guards to other prisoners and the way in which guards speak about prisoners to other guards. Analysis of the results indicated that both groups had negative perceptions of the members of the other group and that little friendly interaction was perceived by either guards or prisoners. In most cases, participants reported a neutral feeling about their interactions. (Author/GW)
