Reflex Responses

From EuroVR Knowledge Base

Description

Held & Durlach (1991) first proposed to use reflex responses as a measure for presence. Loomis (1992) suggests reflex responses as a method for discriminating between presence (the experience of being in a VE) and distal attribution (the experience of being in touch with a VE). Loomis argues that the observer will only show reflex responses to stimuli if s/he experiences them as “real”. Nichols et al. (2000) examined reflex responses to a startle event as a measure for presence. Three categories of reactions were identified: no reaction, verbal report, and physical reaction.
