The aim of the present research is to investigate the importance of individual differences in the recognition of emotional state from nonverbal, visual cues in relation to the work of CCTV operators. An experiment was conducted to determine whether the detection of a gun carrier can be predicted on the basis of an observer's ability to recognize emotion conveyed by non-verbal, visual cues. There was a relationship between the emotional state reported by an individual whilst carrying a firearm and the extent to which an observer was ability to determine whether or not this individual was carrying a gun. It was also found that observers with a high ability to recognize emotion from facial expressions were able to spot a gun carrier more accurately than observers with a low ability in this respect. This small-scale pilot study requires replication with a larger number of participants and real CCTV images.
