The objective of the current study was to assess the effect of voice interactions with an in-vehicle system on drivers’ guidance of attention. Our approach was to examine the effect of voice interactions on endogenous control of attention using a modified Posner cue-target paradigm. Consistent with the bottleneck hypothesis, dual-task slowing was observed when drivers responded to an auditory task and to a pedestrian detection task concurrently. This interference contributed to disrupted attention allocation, especially when drivers could not rely on their endogenous control of attention.
