The value of reaction-time measures for presence research: Empirical findings and future perspectives

A series of experiments (N = 168) was conducted to test the capacity of Secondary Task Reaction Times (STRT) for Presence measurement. Based on recent theories, possible connections between reaction times and Presence were examined in users of a hypertext, a film, and a virtual environment that used the same visual materials. A Presence questionnaire was employed as comparative measure. Findings indicate rather unsystematic and weak convergence between STRT and subjective measures of Presence or underlying processes. A modified STRT paradigm for Presence research is suggested. Keywords--- Spatial Presence, secondary task reaction times, measurement, methodology, objective measure, experiment. 1.
