Abstract

Despite the well-known distracting effects, many drivers still engage in phone use, especially texting and especially among young drivers, with new emerging messaging modes. The present study aims to examine the effects of different answering modes on driving performance. Twenty-four students (12 females), aged between 19 and 25 years (M = 20.83, SD = 1.53), volunteered for the study. They accomplished the Lane Change Task (LCT) with baseline and dual-task runs in a driving simulator. In dual-task runs, participants answered text messages on a smartphone by voice or text message with varying task complexity. Driving performance was measured by lane deviation (LCT) and subjective measures (NASA-TLX). Across all trials, driving performance deteriorated during dual-task runs compared with the baseline runs, and subjective demand increased. Analysis of dual-task runs showed a benefit for voice-based answering to received text messages that leveled off in the complex task. All in all, the benefits of using voice-based answering in comparison with text-based answering were found regarding driving performance and subjective measures. Nevertheless, this benefit was mostly lost in the complex task, and both the driving performance and the demand measured in the baseline conditions could not be reached.
