The 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.

Impulsivity and driver behaviors, offences and accident involvement: A systematic review BIÇAKSIZ, Pinar; Özkan, Türker (2016-04-01) The present literature review study investigated the relationship between impulsivity and driver behaviors, offences and road traffic accidents through the lenses of characterological perspective. The studies published from 1970 to 2014 that examined and reported a relationship between impulsivity and at least one driving related outcome (e.g., a self-report measure of driver behavior) were included. The relevant 38 out of 288 studies are presented in four sections based on the driving related outcomes as; ...
THE MEDIATING ROLE OF DRIVING-RELATED COGNITIONS AND ANXIETY IN THE RELATIONSHIP BETWEEN DRIVING SKILLS AND DRIVING BEHAVIORS Azık Özkan, Derya; Öz, Bahar; Department of Psychology (2022-8-12) Driving skills and driving behaviors, as being the human factors in driving, are the most studied and most influential variables of efforts to sustain a safe traffic environment. Although these factors were investigated in the literature and their relationships with different variables and each other are examined in various studies with various samples; anxiety-related factors have always been evaluated only within limited (avoidant) or clinical groups. However, anxiety, like anger, is a negative emotional ...

The Relationship between Dispositional Affect and Traffic Locus of Control in Driving Arslan, Burcu (2021-10-01) The locus of control and dispositional affect of drivers has been claimed to influence driver behaviors. The positive affect and internal locus of control were usually claimed to be related to safety behaviors, whereas negative affect and external locus of control were shown as related to risky behaviors. To investigate the locus of control in the traffic context, multidimensional traffic locus of control (T-LOC) was developed with four dimensions; self, other drivers, vehicle/environment, and fate. In the ...
Developing the Impulsive Driver Behavior Scale BIÇAKSIZ, Pinar; Özkan, Türker (2016-11-01) The aim of the present study is to develop a driving context specific impulsivity scale. First, a qualitative study was conducted by interviewing 20 individual drivers to develop the scale items based on the definitions of the basic impulsivity dimensions in the literature. Then, a quantitative study with a total of 506 individual drivers to examine the psychometric qualities of the newly developed Impulsive Driver Behavior Scale. In addition, the variance in driver behaviors, namely violations, errors, lap...
