Abstract:A previous study found that environmental cues (noise) and cognitive load (counting one’s steps) potentially increase the detection accuracy of individuals with hostile intentions. The current study aims to replicate these findings while also examining differences in behaviour between hostile and non-hostile individuals and differences in the use of indicators of deception between laypeople and experts. There were no significant effects of cues or cognitive load on the detection accuracy of participants. There were minor differences in behaviours between individuals with hostile and non-hostile intent and minor differences in the use of indicators between police officers and students. However, the indicators of both groups were faulty and contradictory and participants who used more correct indicators did not have a significantly higher detection accuracy. It remains questionable if environmental cues and cognitive load can reliably provoke salient behaviours that make hostile individuals discernible. Several interpretations of these results are offered. Implications for practice are a deliberate and careful handling of and a pragmatic approach to behavioural indicators of deception.
