<p>This study investigates the relationship between driving experience and generalization of driver's stopping behavior. Previous research has suggested that an acquired behavior is triggered by positive reinforcement, and the same behavior is replicated by the same trigger in any situations once it is generalized. Driving behavior is a type of acquired behaviors, and therefore it is possible that a procedure in driving is generalized by accumulating driving experience. This study aims to relate the generalization of driver's stopping behavior to the driver's driving experience by comparing the stopping behavior in real space and virtual space presented by a driving simulator. The results showed that drivers with longer driving experience performed stopping behavior based on the same positive reinforcement regardless of the situations: real space or virtual space, which suggests that their stopping behavior is generalized. On the other hand, drivers with shorter driving experience did not exhibit the generalization in their behavior.</p>
