Chapter 5 100 the interactions with NPCs as standardized as possible, the VR instructors were provided with a script. During the dynamic voice-over interactions, the VR instructors could slightly deviate from the script if the interaction with the police officers necessitated it. For more information on the scenario, we refer readers to Kleygrewe, Hutter and Oudejans (2023). Independent variable AAR Perspective The AAR perspectives used after the VR training consisted of (i) bird’s eye view in combination with police officer perspective, (ii) bird’s eye view in combination with suspect perspective, and (iii) bird’s eye view (as control condition). For perspectives (i) and (ii), the instructors were tasked with switching from a bird’s eye view, adopted during general movement through the virtual environment, to the specific perspective (i.e., police officer or suspect) whenever the participants made contact with a suspect. For perspective (i) this meant that the instructor selected the most relevant police officer perspective from the four team members during the engagement with the suspect (most often, instructors selected the officer who engaged in verbal communication). Perspective (iii), the bird’s eye view, was utilized as a control condition: participants reviewed their performance from the bird’s eye view for both engagement with the suspect and general movement through the environment. Figure 2 shows the different perspectives used in this study.
