Summary
Sanbonmatsu, Strayer, Yu, Biondi, and Cooper (Mountain-Plains Consortium MPC 19-388) examined the cognitive correlates of consumer beliefs about, and confidence in, fully automated vehicles. Participants completed a survey assessing trust, perceived benefits/risks, and willingness to use AVs alongside individual-difference measures of need for cognition, self-regulation, and risk attitude. The companion naturalistic intersection-observation study aimed at distracted-driving self-regulation failed to detect reliable behavioral effects; the AV-attitudes survey study (also published in Transp Res F 55: 114-122) showed that confidence in AV beliefs is dissociable from accuracy and is shaped by need-for-cognition and risk attitudes.
Key finding
Confidence in beliefs about fully automated vehicles is partly dissociable from accuracy and is predicted by individual-difference factors such as need for cognition and risk attitude.
Methodology
MPC technical report combining (a) a survey of consumer attitudes toward fully automated vehicles with cognitive/individual-difference covariates, and (b) a naturalistic intersection-observation study of distracted-driving self-regulation that yielded null behavioral effects.
