Abstract An experimental study was carried out among three groups of children aged 10 to 16 years, two of whom were shown episodes from two UK‐produced police drama series and the other (control group) viewed nothing. Children were tested one week before the viewing sessions and immediately afterwards with a series of questions about their perceptions of the police and police work, their real life contact with the police or crime, and details of their television viewing habits and demography. Both viewing groups were tested for their comprehension of the police drama episode they had been shown. Results showed that older children were better able than younger children to follow dramatic plots, but that the evidence for an effect of single television drama episodes on children's beliefs about the police was less clear‐cut. Both children in the two viewing groups and those in the control group exhibited some shifts in their perceptions of the police. Children who watched the television episodes, however, were more likely to show opinion shifts in relation to specific attributes of the police or police work which were strongly featured in the programmes.
