The relationship between traffic congestion, driver stress and direct versus indirect coping behaviours

Drivers experiencing rush hour congestion were interviewed using cellular telephones to study stress and coping responses. Measures were taken of each drivers predisposition to stress (trait stress) as well as their reactions to the experience of either low or high traffic congestion (state stress). Two interviews were conducted during the trip when drivers experienced both low and high congestion conditions. Although state stress was greatest for all drivers experiencing the high congestion condition, a trait X situation interaction was obtained, indicating that stress levels were highest for high trait stress drivers experiencing the congested roadway. In terms of trait coping behaviours, participants indicated a preference for direct over indirect behaviours. A greater variety of direct and indirect behaviours were reported in high congestion. Reports of aggressive behaviours showed the greatest increase from low to high congestion. Comments on the use of cellular telephones in methodology are offered.

Masculinity and hockey violence

Qualitative research on the relationship between masculinity and hockey violence has suggested that players endorsing traditional masculine behavior were more likely to engage in violence than players who held weaker masculine beliefs. Data were collected from white, middle class players on five Toronto hockey teams representing two different age groups (14.3 and 17.7 years respectively) and skill levels (Bantam and Junior A). Moderate support was found for the predicted relationship between higher masculinity and increased violence, particularly at the preprofessional Junior A level. Subscales of the Brannon Masculinity Scale, applied to a sport situation, were seen to be a valid measure of gender typing. Increased levels of violence (especially fist fights), more than playing or skating skills were seen to lead to greater perception of competence by both teammates and coaches.

Cognitive failures as predictors of driving errors, lapses, and violations

Dual-process models from the cognitive literature have proposed a taxonomy of cognitive failures in everyday activities, and this novel approach was applied to understanding driver behaviour. This framework was used to examine whether categories of cognitive failure would explain driving errors, driving lapses, and driving violations in a sample of undergraduates at a large urban university. Two types of cognitive failure were examined, one associated with missing affective information and the other associated with a failure to engage effortful processes to override an automatic response. Alexithymia was used as an indicator of missing affective information, and attention regulation, reactivity, and impulsivity were used as indicators of override failure. Relevant demographic variables included gender and hours typically driven. Override failures were significantly associated with driving behaviour in the correlational analyses. In the regression analyses, attention regulation predicted driving errors, and gender, attention regulation, and impulsivity predicted driving violations. The implications of this work include the potential application to driver training, to users of informatics devices (e.g., GPS, cellular phones, messaging systems), and for individuals diagnosed with attention and/or impulsivity problems.

Understanding driver anger and aggression: Attributional theory in the driving environment

Two studies tested the applicability of Weiners (1995, 1996, 2001, 2006) attributional model of social conduct to roadway environments. This model highlights the role of inferences of responsibility after making causal judgments for social transgressions. Study 1 employed written scenarios where participants were asked to imagine themselves driving on a major highway. The degree of controllability and intentionality of the driving act was manipulated experimentally by altering the specific event-related details provided to the participants. Study 2 extended this research to life events by having participants complete online driving diaries every 2 days, identifying their most negative/upsetting encounter with another motorist. The most anger-provoking event was selected from among 4 diary entries and participants were asked to respond to a questionnaire similar to that used in Study 1. Path analyses in both studies generally supported predictions derived from Weiners model; the association between perceived controllability, intentionality, and dispositional locus of causality of the negative driving event and subsequent anger was mediated by perceptions of responsibility. Additional results in Study 2 suggested that low perceived controllability, intentionality, and dispositional locus of causality were associated with reduced perceived responsibility, which, in turn, facilitated feelings of sympathy. Anger was associated with aggressive responses to the offending driver, whereas sympathy was associated with prosocial responses. Recommendations were offered for improved driver safety, including the development of attributional retraining programs to combat self-serving attributional biases, teaching novice drivers about both formal and informal roadway communication, and the promotion of forgiveness among drivers

THE INFLUENCE OF MUSIC ON MILD DRIVER AGGRESSION

Abstract Automobile drivers were randomly assigned to either a “music” or “non-music” group. The music group listened to their favorite music, while the non-music group abstained from any music or talk radio, during their entire commute to or from school⧹work. Using a cellular telephone, state measures of driver aggression, time urgency, and stress arousal were obtained during a single commute in low and high congestion conditions. No predictors of mild aggression were found in low congestion. In high congestion, a music X time urgency interaction was found. Mild aggression was lower among those listening to music but only at low levels of time urgency. Results are interpreted in terms of the distractibility and relaxation effects.

Addressing Driver Aggression Contributions From Psychological Science

Aggressive roadway behavior contributes to motor-vehicle collisions, resulting in significant injuries, fatalities, and related financial costs. Psychological models have identified person- and situation-related variables that are predictive of driver aggression, and these have been used to develop strategies to alleviate aggressive roadway behavior. Future psychological research directions are discussed.

Driver anger on the information superhighway: A content analysis of online complaints of offensive driver behaviour

In recent years, several websites have been developed allowing drivers to post their complaints about other motorists online. These websites allow drivers to describe the nature of the offensive behaviour and to identify the offending motorist by vehicle type, colour, and license plate number. Some websites also ask drivers to list the location where the event took place and the exact date and time of the offence. The current study was a content analysis of complaints posted to RoadRagers.com between 1999 and 2007 (N=5624). The purpose of the study was to: (1) assess the research value of this novel data source; (2) demonstrate the value of content analysis to the study of driver behaviour; (3) further validate an existing coding scheme; (4) determine whether this new data source would replicate previous research findings regarding the most frequent types of driver complaints and temporal distribution of these reports; (5) provide recommendations for improved driver training and public safety initiatives based on these data. A coding scheme that was originally developed for an assessment of complaints submitted to the Ontario Provincial Police (OPP) (Wickens et al., 2005) was revised to accommodate the new dataset. The inter-rater reliability of the revised coding scheme as applied to the website complaints was very good (kappa=.85). The most frequently reported improper driver behaviours were cutting/weaving, speeding, perceived displays of hostility, and tailgating. Reports were most frequent on weekdays and during the morning and afternoon rush hour. The current study replicated several findings from the analysis of reports to the OPP, but possible differences in the sample and data collection method also produced some differences in findings. The value of content analysis to driver behaviour research and of driver complaint websites as a data source was demonstrated. Implications for driver safety initiatives and future research will be discussed.

AGE AND VENGEANCE AS PREDICTORS OF MILD DRIVER AGGRESSION

The present study examined the influence of driver age and vengeance on mild aggression among drivers with at least 5 years experience. Mild aggression decreased with age among low vengeance drivers and changed little across age groups among moderately vengeful drivers. However, mild driver aggression actually increased with age among highly vengeful drivers. Results are interpreted in terms of the aggressive nature of an enduring vengeful attitude.

The Effects of Prior Experience with a Task on Subsequent Conformity to a Different Task

Summary Subject correctness and group agreement were seen to interact and generalize across differing classes of experimental tasks to mediate conformity by affecting subjects relative competence. Prior experience with an informational task (the Canadian Knowledge Inventory) generalized to affect conformity on both other informational task items and differing items of a perceptual nature. Subjects were recruited from visitors to the Ontario Science Centre. Those who received experimental manipulations of correctness and agreement which led them to perceive themselves incompetent relative to the group were the most conforming, while those who received experimental manipulations leading to the perception of superior competence were the least conforming. This held true for both manipulated and perceived relative competence. It was further observed as follows: (a) Younger subjects were more conforming only when they perceived themselves less competent than the group. (b) Subject sex interacted with both corr...

Experimental examination of the effects of televised motor vehicle commercials on risk-positive attitudes, emotions and risky driving inclinations

PURPOSE This study examined the short-term effects of risky driving motor vehicle television commercials on risk-positive attitudes, emotions and risky driving inclinations in video-simulated critical road traffic situations among males and females, within an experimental design. METHOD Participants were randomly assigned to one of three televised commercial advertising conditions embedded in a television show: a risky driving motor vehicle commercial condition, a non-risky driving motor vehicle commercial condition and a control non-motor vehicle commercial condition. Participants subsequently completed the Implicit Attitude Test (IAT) to measure risk-positive attitudes, Driver Thrill Seeking Scale (DTSS) to measure risk-positive emotions and the Vienna Risk-Taking Test - Traffic (WRBTV) to measure risky driving inclinations. RESULTS ANOVA analyses indicated that type of commercial participants watched did not affect their performance on the IAT, DTSS or WRBTV. However, a main effect of heightened risk-positive emotions and risky driving inclinations was found for males. DISCUSSION Despite public and governmental concern that risky driving motor vehicle commercials may increase the likelihood that people exposed to these commercials engage in risky driving, this experimental study found no immediate effect of brief exposure to a risky driving motor vehicle commercial on risk-positive attitudes, emotions or risky driving inclinations. Subsequent research should examine the effects of cumulative exposure to risky driving motor vehicle television commercials and print advertisements.
