Abstract:Security officers have the important task to keep public places safe by observing and detecting people with possible hostile intentions. Findings of previous search about this subject are diverse and ambiguous, some researchers have stated people are able to observe and detect deviant behavior, whereas others state that people are no better than chance level in detecting hostile intentions. A recent study from Wijn, Van der Kleij, Kallen, Stekkinger and De Vries (2017) about hostile intentions, however, stated that some conditions could enhance detection levels. The current study will replicate the study from Wijn et al. (2017) to see if cognitive load and environmental cues could improve detection performance. In addition the original study, police officers took part in the experiment, and a comparison with college students is made concerning hostile detection. No main or interaction effects from the different conditions on detection performance were found after performing a 2 x 2 repeated measures ANOVA. Furthermore, there was no difference in detection levels when comparing police officers with college students. However, work experience seemed to be a significant predictor of the detection performance. This current study had different findings from the original study from Wijn et al. (2017). Replication is crucial and in order to get more insight in this field of psychology, future research on this topic is suggested.
