The Effects of psychological inoculation on drivers’ speeding behavior

Simser, Berfin Serenat
Speeding is a widespread problem which can cause life threatening outcomes in traffic settings. The present study was aimed at measuring whether psychological inoculation (PI) based on an integrated model of Theory of Planned Behavior (TPB) and Prototype Willingness Model (PWM) can be used to reduce speeding behaviors of drivers. 95 male drivers aging between 19 and 30 took part in the study. As part of the PI intervention, all participants were given challenging sentences as exaggerated forms of their attitudes and beliefs regarding speeding and asked to refute these statements by developing counterarguments against these beliefs. Before, immediately after and 2 weeks after the implementation of interventions, drivers’ speeding related attitudes, subjective norms, perceived behavioral control (TPB constructs); willingness and prototype perceptions (PWM constructs) as well as intention to speed and their speeding behaviors were assessed via questionnaires. To investigate the effectiveness of PI method, ANOVA was conducted for each construct of the model. Moreover, mediation and regression analyses for three different time points were performed in order to investigate how well this model works. The results revealed that drivers’ speeding related cognitions, intentions and behaviors measured before the intervention were significantly decreased both immediately and 2 weeks after the PI intervention. Furthermore, for each time point, the measured constructs were shown to predict intention and behavior, except for perceived behavioral control and prototype favorability. The current study is, therefore, can provide some insight on which constructs to tackle with and how to reduce speeding behavior of drivers. iding the harasser as coping mechanisms; while perceiving sexist hostility correlated with an inclination towards reporting to authorities and not avoiding the harasser.


The effect of implementation intention on speeding and acceleration overtime: A simulator study
Tekeş, Burcu; Özkan, Türker (2021-11-01)
Speeding is considered a major risk factor for road safety. In this study, implementation intention, which is a type of cognitive intervention, was designed to reduce speeding. Implementation intentions are self-regulatory ‘if-then’ plans, which are the subordinate concepts of goal intentions. Additionally, the type of goal was considered as a factor that could contribute to the subsequent behavior. An approach-type goal aims to achieve a behavior, whereas avoidance-type goals aim to avoid a negative, undes...
The path from traffic accident to posttraumatic stress, posttraumatic growth, and driver behavior change: an examination with rumination and transtheoretical model
Kaçan, Bilgesu; Özkan, Türker; Gençöz, Tülin; Department of Psychology (2017)
The traffic accident is one of the traumatic events with their high occurrence rates, deathful results and psychological consequences. While post-traumatic stress (PTS) is one of the negative psychological causes of traffic accidents, positive psychological experiences such as post-traumatic growth also can be experienced. These experiences with their vital effects have an impact on driver behavior change. In this thesis, the path from traffic accident to PTS, PTG, and driver behavior change was examined wi...
A Multimodal Approach for Aggressive Driving Detection
Kumtepe, Omurcan; Yuncu, Enes; Akar, Gözde (2016-05-19)
Aggressive driving behavior is among the important causes of traffic accidents. Hence, detection of driver aggressiveness has an importance in terms of decreasing the number of traffic accidents. Collected driving data while the vehicle is in traffic can be used to make inferences about the aggressiveness of the driver. In this study, a multimodal method is proposed in order to detect driver aggressiveness. The proposed method is based on utilizing the visual data taken from the on vehicle camera and sensor...
The effect of road safety advertisements on speeding behavior over time: A simulator study
Özkan, Özgün; Özkan, Türker; Department of Psychology (2022-3)
Countermeasures to prevent death and injury in traffic are important for traffic safety. Human error is a critical component associated with road traffic accidents. Therefore, various organizations and decision-makers are trying to prevent risky behaviors via different methods. One of the most used methods of raising awareness and creating behavioral change is traffic safety campaign videos. The focus of the present study is speeding, which is one of the most dangerous violations on the road. The study aime...
The role of driver behavior, skills, and personality traits in traffic accidents
Sümer, Nebi; Özkan, Türker (2002-12-01)
Traffic accidents area leading cause of death in Turkey. Past research on traffic psychology has clearly revealed that human factors play the chief role in road crashes, and driver behaviors, skills, risk-oriented personality traits, and psychological symptoms are the specific contributors of these factors. The present study was conducted to examine the role of driver behaviors, skills, some personality constructs, and psychological symptoms in predicting accidents and negative driver outcomes. A total of 3...
