 During Distracted Driving?}, volume = {6}, year = {2011}, url = {https://pubs.lib.uiowa.edu/driving/article/id/28687/}, issue = {2011}, doi = {10.17077/drivingassessment.1415}, abstract = {<p>During distracted driving, people commonly alternate or interleaveattention between driving and another task. One factor that influences taskinterleaving is task structure. Specifically, people tend to switch between tasks atsub-tasks boundaries. Uncertainty about the roadway environment during glancesaway from the road, however, may play a larger role in shaping task interleavingstrategies during distracted driving. The purpose of this study was to examine taskinterleaving strategies when drivers completed a distracting task of various subtasksizes. Participants entered phone numbers, modified zip codes, or digitstrings while performing a lane-keeping task. In general, the time between buttonpresses in the secondary task was significantly greater between sub-tasks thanwithin sub-tasks. However, as sub-tasks became larger drivers switched morefrequently within sub-tasks than between sub-tasks. Additionally, participants’ didnot change their visual sampling strategies as the size of sub-tasks increased.Thus, uncertainty influenced decisions to switch between two interleaved tasks inthe driving environment more than sub-task boundaries.</p>}, month = {6}, pages = {321-328}, publisher={University of Iowa}, journal = {Driving Assessment Conference} }
