Incident perception by British police officers

This study compared the perceptions of a group of experienced British police officers with those of a group of young British police officers and of a group of British civilians. Subjects were shown a videotape of an urban street corner scene which contained a number of staged incidents including criminal offenses, suspicious circumstances, and traffic offenses. They were asked to note down all the incidents which they perceived during the viewing of the videotape, No significant differences were found between the three groups in the total number of incidents identified. There was, however, a significant subject group by offense type interaction, with inexperienced police officers showing the highest reporting of traffic offenses and experienced police officers the lowest. In each group there was also an inverse relationship between the number of traffic offenses and criminal offenses/suspicious circumstances noted. This was particularly high in the inexperienced police officer group.
