|Abstract: ||Illegal gun possession is an increasing problem in the UK; at the same time the UK
has a massive CCTV deployment. Individuals can detect the emotional state of people
shown in image sequences. Additionally, firearms are known to elicit certain
emotional states in their bearers. Consequently, it may be possible for CCTV
operators to determine if surveillance targets are carrying a concealed firearm on the
basis of the target s emotional state. This study investigated whether observers are
able to perceive differences in the emotional states of people who are and who are not
carrying concealed firearms, as judged monitoring staged CCTV footage. Thirty-one
participants viewed 24 mock CCTV clips of individuals walking. Half of the clips
featured a concealed firearm, the other half featured a concealed, innocuous object.
The results showed that observers were able to differentiate between the two clip
types by attributing different moods to those featured in each. However, their
estimation of mood was dissimilar to the mood reported by those featured in the clips.
Furthermore, observers non-verbal sensitivity and their ability to recognize the mood
of carriers showed little relationship. These issues are discussed with regard to the
visual cues associated with this mood recognition task.|
