Assessment of computer-based and self-reported hazard perception skills among drivers : the role of personality and driving skills

Ünal, Ayça Berfu
The aim of the present study was to investigate the correlates and predictors of hazard perception skill among drivers. Specifically, it was examined whether novice and experienced drivers would differ from each other in terms of hazard perception skill. In addition, the role of personality factors and driving skills in predicting hazard perception among drivers was inspected. Drivers’ hazard perception skills were assessed by using both a computer-based hazard perception latency test (Turkish Hazard Perception Test in Traffic) which consists 31 video clips recorded in real traffic, and a self-report measure (Self-Reported Hazard Perception Scale). Following the completion of hazard perception measures, Turkish drivers (N = 135; 90 males, 45 females) also responded to the measures of driving skills, big five personality factors, and sensation seeking. The results of the study indicated that both computer-based and self-reported hazard perception measures significantly differentiated novice and experienced drivers after controlling for the effects of age. Results of the regression analyses demonstrated that computer-based hazard perception skills were significantly predicted by perceptual motor skills subscale of the Driving Skill Inventory. Self-reported hazard perception skill was also strongly predicted by age and perceptual motor skills. The results further revealed that sensation seeking and big five traits did not predict either the computer-based or the self-reported hazard perception skill among drivers. It was concluded that the effects of personality factors could be more observable in on-road assessment of hazard perception. However, the significant difference between novice and experienced drivers showed that hazard perception training should be included to the driver-training curriculum in Turkey as an intervention to promote young novice drivers safety. The findings of the present study were argued in the light of the literature and in relation to the implications for traffic safety in Turkey. Additionally, limitations of the study and suggestions for future researches were discussed.


Illusion of control, optimism bias and their relationship to risk-taking behaviors of Turkish drivers
Doğan, Ebru Burcu; Lajunen, Timo; Department of Psychology (2006)
The aim of the represent research was to investigate the relationship between illusion of control, optimism bias, locus of control, and drivers’ risk-taking behavior among Turkish drivers. A total of 307 drivers completed the Driver Behavior Questionnaire, the Driver Skills Inventory, the Optimism Bias Scale, the Multidimensional Traffic Locus of Control Scale, and Rotter’s Internality Externality Scale. In chapter one, comparison between perceived risk as driver and perceived risk as passenger demonstrated...
Visual perspective in causal attribution, empathy and attitude change
Onder, OM; Öner Özkan, Bengi (SAGE Publications, 2003-12-01)
The aim of the present study was to test the effect of visual perspective on the actor-observer bias. For this aim, we examined the effects of different visual perspectives on individuals' external and internal attributions. In addition to this, we examined the presence or absence of an attitude change toward the death penalty due to participants' visual perspective. One week before the experiment, we measured the participants' attitudes toward the death penalty. Then, during the experiment, films produced ...
Measurement of transformational leadership through a conditional reasoning test
Demiran, Ayça; Toker, Yonca; Department of Psychology (2015)
The aim of the current study is to assess transformational leadership proclivities based on the Conditional Reasoning Test approach (CRT; James, 1998). The CRT is a relatively new implicit assessment system that is used to identify the justification mechanisms (i.e. cognitive biases) indicative of specific motives which underlie personality (James, 1998). ‘Justification mechanisms’ (JMs) are rational and sensible explanations- in contrast to irrational and foolish- that people are inclined to produce for th...
Development of the professional driver behavior questionnaire
Yılmaz, Şerife; Öz, Bahar; Özkan, Türker; Department of Psychology (2018)
The aim of the present study was to develop a comprehensive scale measuring professional drivers' driver behaviors. For this reason, a semi-structured interview form was prepared and applied to different professional driver groups in order to collect behavioral examples displayed in traffic context (Study 1). These examples were grouped based on Reason's taxonomy of human error and Professional Driver, Driver Behavior Scale (PDBQ) was developed. PDBQ along with some other behavior scales such as ODBQ and DB...
Predictor variables of psychological distress and perceived growth following motor vehicle accidents
Birol, Aşkım Sevinç; Karancı, Ayşe Nuray; Department of Psychology (2004)
This study aimed to examine the predictor variables of psychological distress and perceived growth among the survivors of motor vehicle accidents. Demographic characteristics as pre-accident variables, cognitive appraisals of the accident as accident related factors, coping strategies and social support as post-accident variables were used as predictors of distress and perceived growth. 200 adults (142 males and 58 females, ages between 18 and 65) participated in the study. Data was collected by a questionn...
