There are many textbooks claiming to note cues indicative of interpersonal violence. However, many of these are contradictory or are invalidated. With this, there has been a recent increase in research exploring interpersonal threat, including rating cues based on the concern they cause. However, research has used images and written descriptions, and as such the current PhD projects aims to improve the ecological validity of threat detection using a range of novel methods in regard to the research area. Overall, this PhD aims to develop a tool to assess threat detection abilities, as well as understanding how expertise is developed and the experience of assault survivors. We are fortunate to be collaborating with the amazing North Wales Police.
