Dissertation/Thesis Abstract

Stimulus-Response Compatibility Effects on Driver Response Direction
by Katz, Noam A., M.S., California State University, Long Beach, 2020, 50; 27834437
Abstract (Summary)

Human error, such as poor decision-making, is responsible for 94% of vehicle collisions. A collision avoidance system (CAS) is technology that exists in cars to alert drivers of nearby hazards on the road by displaying auditory and visual alerts. A localized auditory alert can be used in a car to facilitate faster collision avoidance maneuvers by the driver. Responses to such localized alerts may be affected by both stimulus-response compatibility (SRC) and approach-avoidance behavior.

The current study examined the specific contributions of these two factors in successful collision avoidance with directional CAS. Participants turned a steering wheel toward or away from pleasant and unpleasant auditory alerts containing varying levels of urgency. The alert indicated the side of safety or the side of the collision. In accordance with SRC effects, it was predicted that an alert on the side of safety (opposite the collision) would lead to reduced collisions; however, this effect may be mediated by the valence (pleasant or unpleasant) of the alert itself. It was expected that increased urgency (rapidity) of the alert would further magnify the effect of alert side and valence.

Results support previous research on SRC and show that urgency affects response selection, thereby allowing for faster responses. Although valence did not mediate the SRC effect as hypothesized, it did mediate the effect of urgency. Additional findings, limitations, and CAS design recommendations are discussed.
