The MAXLab aggression and bystander intervention scenario set (MAXLab_ABISS): A modular scenario set for studying decision making in situations of interpersonal violence in virtual reality

Abstract Objective This Research Note describes the MAXLab Aggression and Bystander Intervention Scenario Set (MAXLab_ABISS) and provides empirical examples of its applicability. We describe the scenarios, elaborate on the production process, provide technical specifications, and explain how materials can be obtained. Method This modular stimulus set, which is currently available in the English, German and Dutch language, includes 360° videos for studying decision-making in interpersonal violence. It offers researchers a complimentary method to collect data on emotions, perceptions, and reactions to violent situations using immersive technology. Results Analysis from two samples (n = 101 and n = 55) show the immersive scenarios of the stimulus set are effective at evoking targeted emotional experiences at the moment of a crime decision. Conclusion MAXLab_ABISS is a safe and effective tool for studying decision making in real-life, emotion-laden criminogenic settings. We offer insights for how researchers can further use the materials to study decision making related to crime and violence.
