The aim of the present research is to investigate the importance of individual
differences in the recognition of emotional state from non-verbal, 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.
