Immersive VR for investigating threat avoidance: The VRthreat toolkit for Unity

Area of Science:

• Psychology
• Computer Science
• Neuroscience

Background:

• Survival necessitates threat response in all animals.
• Human threat-related behavior research is ethically constrained.
• Sophisticated threat avoidance behaviors are observed in non-human animals.

Purpose of the Study:

• To introduce a novel immersive virtual reality (VR) toolkit for assessing human threat-related behavior.
• To overcome ethical limitations in studying human threat avoidance.
• To facilitate research on human responses to immediate survival threats.

Main Methods:

• Development of a VR toolkit using the Unity engine.
• Inclusion of naturalistic environments, interactive objects, and animated threats.
• Utilizing pre-sequencing tools for threat movement and collecting behavioral, movement, and eye-tracking data.

Main Results:

• The toolkit enables the creation of semi-interactive, semi-realistic threat encounters.
• Researchers can design custom experimental 'episodes' for VR.
• The system facilitates the collection of rich behavioral and physiological data.

Conclusions:

• The VR toolkit provides a novel, ethical method for studying human threat avoidance.
• This tool can bridge the gap in understanding human behavioral responses to threats.
• Facilitates advanced research in psychology and neuroscience using immersive VR technology.
