North Carolina State University 640 Poe Hall, Raleigh, NC, 27695-7650, USA Virtual Reality (VR) is used to exam ine the effect of different warnings on behavioral compliance. Sixty uni versity students performed a virtual end-of-day routine security check and interacted with four workplace ISO type warn ings and three posted signs. The scenario was designed so that warn ing presentation was not pre-cued or expected. Other signs, however, were pre-cued; these were expected because they were part of the instructed tasks that were carried out. Participants were randomly to static vs. dynamic conditions. Behavioral complian ce was measured according to whether participants followed the directive to press particular panel buttons. Data demonstrate that dynamic warnings produce higher behavioral compliance than static ones, but there were no dynamic vs. static differences for the pre-cued posted signs. Implication s arising from the use of this technique and resultant findings are discussed.
