Article Citation - WoS: 12Citation - Scopus: 13The differential associations of functional and dysfunctional impulsivity with driving style: A simulator study(Elsevier Sci Ltd, 2019) Bicaksiz, Pinar; Bıçaksız, Pınar; Ozturk, Ibrahim; Ozkan, Ttirker; 163626; PsikolojiThe present study investigated the impulsivity and driving style link by measuring driver behaviors on the driving simulator. Previous studies examining this relationship mostly used self-report instruments to measure both impulsivity and driving related outcomes, therefore this study aims to test this association by using a relatively more objective measurement tool than self-report. Moreover, the associations of functional impulsivity dimension with driving style has been investigated, in addition to the dysfunctional impulsivity dimension, which has been predominantly studied in the literature. Finally, both general and driving context specific functional and dysfunctional impulsivity dimensions were included in the analyses of the current study. Eighty (40 women) young drivers (19-25) participated in the present simulator study, and functional and dysfunctional impulsivity dimensions yielded different patterns of associations with driver behavior measures on the simulator. For instance, functional impulsivity yielded significant associations with standard deviation of lateral lane position, while dysfunctional impulsivity was significantly associated with mean velocity. Eye-movements of the participants while driving on the simulator were also recorded and examined as an explorative effort. The findings are discussed with regard to previous research.

The purpose of this study was to evaluate the reliability and validity of the Impulsive Driver Behavior Scale (IDBS, Bicaksiz & Ozkan, 2016a) with a Chinese sample. Two hundred and ninety-nine drivers completed the Chinese version of the Impulsive Driver Behavior Scale, the Driver Behavior Questionnaire, the Big Five Inventory and some social-demographic and traffic violation items. A confirmatory factor analysis indicated that a four-factor solution with 20 items yielded a better fit to the data than other solutions. The reduced IDBS showed good reliability and a stable structure. Drivers' functional impulsivity was positively correlated with positive driver behavior and some ordinary violations. Meanwhile, the other three dimensions of dysfunctional impulsivity showed negative correlations with positive driver behavior and positive associations with aberrant driving behavior and penalty points and fines. Impulsive driver behavior is also associated with agreeableness and conscientiousness. These results provide evidence supporting the IDBS as a reliable and valuable instrument for measuring driving impulsivity in the Chinese traffic environment. (C) 2019 Elsevier Ltd.

This study directly manipulated information bandwidth of an in-vehicle monitor and asked young drivers to perform the number judgment task during simulated driving. Results show that the drivers produced more number of off-road glances and longer summed excess glance durations in 1.5-second threshold when the in-vehicle task imposed greater information processing demand. The crash risk estimated from the obtained summed excess glance durations is 3.2 times higher when the information processing demand was high than low using the 1.5-second threshold, and 4.3 times higher using the 2.0-second threshold. In practice, designers of in-vehicle technologies should consider information-processing demands of in-vehicle tasks that the technologies require in order to minimize the frequency of excessively long off-road glances during drivingArticle Citation - Scopus: 1Drivers’ Self-Reported Reasons of Speeding: A Turkish Driver Sample from Two Cities(Gioacchino Onorati Editore, 2019) Bıçaksız, P.; Bıçaksız, Pınar; Doğruyol, B.; Erdost, B.G.; Hoe, C.H.; Gupta, S.; Lajunen, T.; Özkan, T.; 163626; PsikolojiSpeeding is an important risk factor of road traffic crashes, and identifying the factors associated with speeding is crucial for road safety. In the present study, face-to-face roadside interviews were conducted to investigate the reasons of speeding among Turkish drivers at six different data collection times in two different cities. A structured interview was administered to collect data from a total of 3317 and 1559 drivers in Ankara and Afyon cities, respectively. Results from the two cities consistently revealed that drivers’ self-reported speeding frequency was partially determined by gender and age. Also, perceiving speeding as a cause of crashes was associated with lower frequency of speeding. Finally, thinking that speed tickets are a means for increasing government income and that it would be safe to exceed the speed limit if driving “safely” was positively associated with frequency of speeding. These findings indicate the importance of norms and (biased) perceptions in speeding behavior. © 2019, Gioacchino Onorati Editore.

However, whether their poorer attention maintenance ability depends on complexities of in vehicle technologies has been underexplored. This study directly manipulated information bandwidth (easy or complex) of an in-vehicle monitor and asked twenty-four drivers aged 18-21 to perform a visual number judgment task with either 5 digits (easy) or 11 digits (complex), during simulated driving. Participants had to verbally respond within 15 s whether each string of presented digits contained more odd or even digits. Eye movements were recorded using an eye tracker. Results show that the drivers produced a greater number of off-road glances and longer summed excess glance durations under a 1.5-s threshold when the in-vehicle task imposed greater information processing demand. In practice, designers of in-vehicle technologies should consider information-processing demands of in-vehicle tasks required by the technologies to minimize the frequency of excessively long off-road glances during driving.

Çalışmanın örneklemini anketleri kağıt-kalem testi olarak (n = 158)ve internet üzerinden (n = 348) dolduran toplam 506 bireysel sürücü oluşturmaktadır. Dürtüsellik kişilik özelliğiningenel psikoloji literatüründeki olumsuz davranış örüntüsü tanımını yansıtan işlevsiz dürtüsellik boyutunun sürücülükbecerileriyle ilişkisiyle işlevsel dürtüsellik (Dickman, 1990) boyutunun sürücülük becerileriyle ilişkisi karşılaştırılmış ve hem korelasyon hem de regresyon analizlerinde farklılaşan örüntüler gözlenmiştir. Ayrıca, sürücüluk bağlamına özel dürtüsellik ve genel dürtüsellik ölçeklerinin sürücülük becerilerinde açıkladıkları varyans oranları karşılaştırılmış ve sürücülük bağlamına özel dürtüsellik ölçeğinin sürücülük becerilerinde daha yüksek oranda varyansaçıkladığı görülmüştür. Bu nedenle, sürücülukle ilgili değişkenleri daha iyi anlamak ve açıklamak için yürütülecekçalışmalarda sürücülük bağlamına özel dürtüsellik kavramının ve ölçeğinin kullanılmasının ilgili literatüre katkıyapma potansiyeline sahip olduğu önerilebilir.Article Citation - WoS: 9Citation - Scopus: 12Implicit Evaluations About Driving Skills Predicting Driving Performance(Elsevier Sci Ltd, 2018) Bicaksiz, Pinar; Bıçaksız, Pınar; Harma, Mehmet; Dogruyol, Burak; Lajunen, Timo; Ozkan, Turker; 163626; PsikolojiSelf-reported measures of driving skills have the potential shortcomings of the general self report methodology such as social responding and self-enhancement biases. In the present study, the Implicit Association Test (IAT) procedure was adapted to measure the implicit evaluations of driving skills. The performance of IAT and an explicit, self-report measure of driving skills were compared in predicting driver behaviors and performance. Ninetyone Turkish male drivers participated in the study. The results showed that the implicit test and the self-reported driving skills scale showed different patterns of relationships with the outcome measures in the regression analyses. In addition, the implicit measure of driving skills moderated the relationship between self-reported driving skills and some of the outcome measures used in the current study. These results support the need to use the implicit measures in addition to self-report measures to better understand drivers evaluations of their driving skills, which has the potential to influence their risky driving.

The current driving simulator experiment examined the additive effects of expert eye movement videos following RAPT training on young drivers' hazard anticipation performance compared to video-only and RAPT-only conditions. The study employed a between-subject design in which 36 young participants (aged 18-21) were equally and randomly assigned to one of three experimental conditions, were outfitted with an eye tracker and drove four unique scenarios on a driving simulator to evaluate the effect of treatment on their anticipation skills. The results indicate that the young participants that viewed the videos of expert eye movements following the completion of RAPT showed significant improvements in their hazard anticipation ability (85%) on the subsequent experimental evaluation drives compared to those young drivers who were only exposed to either the RAPT training (61%) or the Video (43%). The results further imply that videos of expert eye movements shown immediately after RAPT training may improve the drivers' anticipation skills by helping them map and integrate the spatial and tactical knowledge gained in a training program within dynamic driving environments involving latent hazards.
