Issue Date: | 2018 | Source: | ERGONOMICS, 61 (3), pp. 429-443 | Abstract: | Intersection accidents result in a significant proportion of road fatalities, and attention allocation likely plays a role. Attention allocation may depend on (limited) working memory (WM) capacity. Driving is often combined with tasks increasing WM load, consequently impairing attention orienting. This study (n = 22) investigated WM load effects on event-related potentials (ERPs) related to attention orienting. A simulated driving environment allowed continuous lane-keeping measurement. Participants were asked to orient attention covertly towards the side indicated by an arrow, and to respond only to moving cars appearing on the attended side by pressing a button. WM load was manipulated using a concurrent memory task. ERPs showed typical attentional modulation (cue: contralateral negativity, LDAP; car: N1, P1, SN and P3) under low and high load conditions. With increased WM load, lane-keeping performance improved, while dual task performance degraded (memory task: increased error rate; orienting task: increased false alarms, smaller P3). Practitioner Summary: Intersection driver-support systems aim to improve traffic safety and flow. However, in-vehicle systems induce WM load, increasing the tendency to yield. Traffic flow reduces if drivers stop at inappropriate times, reducing the effectiveness of systems. Consequently, driver-support systems could include WM load measurement during driving in the development phase. | Notes: | Ross, V (reprint author), Hasselt Univ, Transportat Res Inst IMOB, Sch Mobil Sci, Diepenbeek, Belgium. veerle.ross@uhasselt.be | Keywords: | attention orienting; working memory load; event-related potentials; driving simulation | Document URI: | http://hdl.handle.net/1942/24326 | ISSN: | 0014-0139 | e-ISSN: | 1366-5847 | DOI: | 10.1080/00140139.2017.1353708 | ISI #: | 000423595800008 | Rights: | © 2017 Informa UK Limited, trading as Taylor & Francis Group | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2019 |
