Key Points

The aim was to investigate the connection between trust and behavior in high-risk human-automation interactions.
Developed the Virtual Reality Testbed for Risk and Automation Studies (ViRTRAS) to manipulate risk through varying heights and potential falls.
Conducted three primary studies to assess how risk influences trust and behavior.
Analyses included mediation models to evaluate the relationship between trust measures, system reliability, and behavior.
Risk manipulation was effective, influencing trust and behavior.
The effect of function allocation was replicated but weakened under risk; reported trust remained constant.
Only one trust measure mediated the relationship between system reliability and behavior, specifically under risk.

Examines the impact of risk on trust and behavior in human-automation interactions, suggesting integration of risk enhances validity.
