The Relationship Between Inhibitory Control Ability And Driver's Risky Driving Behavior: ERP Research

In recent years,a large number of domestic and foreign researches show that:traffic accidents caused by human factors are more than 90%,which shows that people are the main factors in road accidents.Past studies show that drivers not only need to have ability to control the vehicle and road traffic situation,the physiological and psychological characteristics of drivers themselves are also important factors,which can affect the driving safety.Therefore,it is of great practical and theoretical significance to explore the influence of driver’s own ability on dangerous driving behavior from the driver’s own self.Inhibitory control has always been the focus of many researchers,which can not only explain the differences and development of different individuals,it also involves the development of emotional regulation and social competence.Studies on the relationships between inhibitory control and dangerous driving behavior,foreign scholars have carried out a lot of research objects,but most researches were focus on youth groups,moreover,the method is unitary.In most cases,impulsivity were measured to represent the ability of inhibitory control,which can not reflect the actual behavior.Although some researchers have begun to explore relatively objective research methods,different objective measurement methods have drawn inconsistent experimental results,and no researchers have conducted studies on neural mechanisms.The event-related potentials technique,known as its high temporal resolution in milliseconds,is an ideal method to more precisely examine alterations in the dynamic time course of neural activity of the impact of inhibition control on dangerous driving behavior.Therefore,the purpose of the current research was to investigate how inhibitory control on dangerous driving by using the event-related potentials technique.We used the classic paradigm Go/NoGo task as the measurement of inhibitory control,the Manchester Driver Behavior Questionnaire(DBQ),Dula Dangerous Driving Index(DDDI),and driving simulator respectively as subjective and objective indicators of dangerous driving.This study consists of two experimental components:Exp1:Explored whether there are differences in individual dangerous driving behavior between drivers with different inhibitory control ability.According to the indicator of the Go/NoGo task,we divided participants into two groups,30 drivers with low ability of inhibitory control,and 31 drivers with high ability of inhibitory control,The results showed that compared with the drivers with high ability of inhibitory control,the drivers with low ability of inhibitory control has more dangerous driving behavior.Exp2:The relationship and the process of neural dynamic processing between inhibitory control and dangerous driving behavior and the process of neural dynamic processing were explored.The main results are as follows:(1)The lapse dangerous driving behavior may relate to the drivers’ conflict monitoring capability,reflecting on decreased NoGo-N2 amplitude.(2)The error dangerous driving behavior may relate both to the conflict monitoring and the movement restraint,reflecting on decreased NoGo-N2 amplitude and increased NoGo-P3 amplitude.(3)A driver,who has negative emotions or is prone to cause negative emotions in traffic scenes such as traffic jam,it will be easier to show impulsive driving,reflecting on the shortening NoGo-N2 latency and NoGo-P3 latency.(4)The more effort or cognitive resources it takes for the distractor in the late stage of inhibition control,the better the driver’s control of vehicle and speed during daily driving,which is reflected in the increased NoGo-P3 amplitude.This research not only facilitates the understanding of the relationships between cognitive ability and dangerous driving,but also provides scientific indicators and theoretical basis for drivers’ selection and assessment.
