Abstract

The present study examines the effects of mobile phone dependency and passive mobile phone interaction on situation awareness and driving performance. A total of 53 participants drove in a high-fidelity driving simulator which included a mix of city, rural, and residential streets. As participants were driving, they received a text message to which they were unable to respond (their phone was placed out of reach but audible and visible). After receiving the text message, participants' situation awareness was assessed via the Situation Awareness Global Assessment Technique (SAGAT; Endsley, 1995). SAGAT probes occurred at both 30 s and 10 s after the text message was delivered to determine the effect of text message delay on situation awareness. Results indicate that situation awareness is negatively affected for at least 10 s after the text message alert, but not longer than 30 s. In addition to lowered situation awareness, participants' mean speed increased during periods of distraction in the 10 s following a mobile phone notification. The implications of passive mobile phone interaction, as well as possible solutions are discussed.
