Revisiting the use of secondary task reaction time measures in telepresence research: exploring the role of immersion and attention

In this experimental study, we use secondary task reaction time (STRT) to measure Attention to a media presentation and compare STRT to traditional self-report measures of Telepresence (immersion, social reality, spatial presence, and transportation) and enjoyment. Further, we compare the STRT measure with the composite items of Telepresence–Immersion. The results indicate that STRT may be useful for measuring some sub-dimensions of Telepresence. Implications are discussed
