The effects of speech production and speech comprehension on simulated driving performance

Abstract

We performed two experiments comparing the effects of speech production and speech comprehension on simulated driving performance. In both experiments, participants completed a speech task and a simulated driving task under single-and dual-task conditions, with language materials matched for linguistic complexity. In Experiment 1, concurrent production and comprehension resulted in more variable velocity compared to driving alone. Experiment 2 replicated these effects in a more difficult simulated driving environment, with participants showing larger and more variable headway times when speaking or listening while driving than when just driving. In both experiments, concurrent production yielded better control of lane position relative to single-task performance; concurrent comprehension had little impact on control of lane position. On all other measures, production and comprehension had very similar effects on driving. The results show, in line with previous work, that there are detrimental consequences for driving of concurrent language use. Our findings imply that these detrimental consequences may be roughly the same whether drivers are producing speech or comprehending it.

Allocating Visual Attention: How Relevance to Driving Impacts Attention when Drivers are Distracted

“…Speed and steering angle were found to be more variable when the driver was distracted, replicating results found in previous research (e.g., Kubose, Bock, Dell, Garnsey, Kramer, & Mayhugh, 2006;Liang & Lee, 2010).…”

A decrease in brain activation associated with driving when listening to someone speak

“…In particular, multitasking of driving and conversing on a cell phone is technologically available, but intuitively seems dangerous in some circumstances. Although driving becomes sufficiently cognitively automated (Schneider, 1999) to permit experienced drivers to perform other tasks at the same time, such as carrying on a conversation, a large number of behavioral studies have now shown that performing another cognitive task while driving an actual or virtual car substantially degrades driving performance Nilsson, 1994, 1995;Anttila and Luoma, 2005;Beede and Kass, 2006;Brookhuis et al, 1991;Consiglio et al, 2003;Drory, 1985;Engström et al, 2005;Haigney et al, 2000;Hancock et al, 2003;Horberry et al, 2006;Horrey and Wickens, 2004;Hunton and Rose, 2005;Jamson and Merat, 2005;Kubose et al, 2006;Lamble et al, 1999;Lesch and Hancock, 2004;Liu and Lee, 2005;Matthews et al, 2003;McKnight and McKnight, 1993;Patten et al, 2004;Ranney et al, 2005; Nunes, 2000, 2003;Santos et al, 2005;Shinar et al, 2005; Drews, 2004, 2007;Strayer et al, 2003Strayer et al, , 2006Strayer and Johnston, 2001; Bolling, 2005, 2006;Treffner and Barrett, 2004). Although some of these studies show that some aspects of driving are unaffected by a secondary task (e.g., Haigney et al, 2000) and in some cases certain aspects improve (e.g., Brookhuis et al, 1991;Engström et al, 2005), a recent meta-analysis of the literature suggests a large overall decrement in driving performance when a secondary task is added (Horey and Wickens, 2006).…”

The Effect of Voice Interactions on Drivers’ Guidance of Attention

“…Although Kubose et al (2006) found similar driving performance (e.g., control of velocity and maintenance of headway time) during listening and responding to auditory messages, our results suggest that voice interactions have the potential to impair drivers' attention allocation, especially when they can not rely on their endogenous control of attention.…”
