Conversation Disrupts Change Detection in Complex Traffic Scenes

Abstract: A set of studies examined the effects of cognitive distraction on visual scanning and change detection in natural traffic scenes. Experiment 1 found that a naturalistic hands-free phone conversation could disrupt change detection, thereby degrading the encoding of visual information and increasing the frequency of undetected changes. Data also revealed a tendency for conversation to impair knowledge-driven orienting of attention in older adults. Experiment 2 found that an attentive listening task produced no s… Show more

“…It remains possible however that the act of producing a commentary may evoke shorter fixations for a different reason than a reduction in the processing difficulty of the fixated object. Although an increase in spatial load can lead to longer fixation durations while driving (Recarte & Nunes, 2000), non-spatial secondary tasks have been associated with a decrease in fixation durations during driving (Nunes & Recarte, 2002), as has naturalistic conversation (McCarley et al, 2004).…”

“…However, non-spatial cognitive loading tasks, including autobiographical memory recall and currency conversion tasks, have been shown to reduce fixation durations while driving (Nunes & Recarte, 2002). More specifically, naturalistic conversation while driving has also been associated with a decrease in fixation duration (McCarley et al, 2004). In this case longer response times to hazards suggest that shorter fixations are caused by the secondary task of producing a verbal commentary due to increased verbal cognitive load, rather than the more rapid processing of the visual scene observed in expert drivers.…”

“…However, shorter fixations have also been observed in driving tasks, while carrying out nonspatial secondary tasks (Nunes & Recarte, 2002) or during naturalistic conversation (McCarley et al, 2004). Therefore, if shorter fixations are associated with all speaking conditions it is likely that they are caused by increased verbal workload, rather than a potentially beneficial effect of training.…”

“…If commentary exposure produces shorter fixation durations then this may give us hope that commentary exposure is encouraging more rapid processing of the content of fixations, as is seen in experienced drivers relative to novice drivers (Chapman & Underwood, 1998). However, it is also possible that the shorter fixation durations are due to the production of a commentary, as shorter fixation durations have been associated with increased verbal workload (McCarley et al, 2004). Since Young et al (2014) did not test silent hazard perception ability after commentary exposure or practice, it was not possible to establish whether shortened fixation durations were due to the production of speech or an effect of commentary exposure.…”
