In this preliminary study involving 30 police school trainees, Interpersonal Process Recall project stimulus films were used in an effort to sensitize policemen to their aggressive feelings and self-control problems in dealing with riots, demonstrations, and other stressful situations. During six filmed vignettes progressing from mild to intense degrees of rejection, viewers were instructed to imagine that the actor was talking to them directly and privately, and in the last vignette, to respond aloud to the actor's comments. Control of strong hostile impulses was discussed in the context of the special demands of the policeman's role. The next step may be to develop films directly relevant to both normal and exceptional police duties. (Six references are included.) (ly)
