This study examines whether there is evidence that converging theories from the domains of risk and decision making, neuroscience, and psychology can improve our understanding of how drivers learn to appraise on-the-road hazards. Within the domain of decision making it is suggested that there are two distinct ways in which humans appraise risk: risk as feelings and risk as analysis. Meanwhile, current neurological theory, in the form of the Somatic Marker Hypothesis, supports the role of feelings and emotion as an evolved automated system of human risk appraisal that biases judgment and decision making. This study used skin conductance responses (SCRs) to measure learner, novice and experienced drivers’ psycho-physiological responses to the development of driving hazards. Experienced drivers were twice as likely to produce an SCR to developing hazards as novice drivers and three times as likely …
