Is all high-risk behaviour premeditated? A qualitative exploratory approach to the self-regulation of habitual and risky driving behaviours

The majority of research surrounding the intervention of risky driving behaviours has operated on the notion that offending behaviour is intentional, leading to a defined theoretical approach on deterrence. This study aimed to investigate the motivations, regulatory behaviours and resisting beliefs that contribute to the occurrence of risky driving behaviours, from the perspective that some behaviour may be unintentional and habitual by nature. An online sample of Australian drivers (N = 46) were recruited to complete a qualitative phone interview regarding their perceptions of risky driving behaviours. Thematic analysis revealed that firstly, speeding and the use of technology while driving (i.e., distraction) were the most commonly reported risky driving habits. Speeding in particular appeared to be both habitual and unintentional, whereas phone use while driving was attributable to addiction, impulses and attitudes. Factors such as drivers’ mentality, the automaticity of the behaviour, and social norms were perceived to make habitual behaviours more difficult to change, whilst personal experiences with legal and physical consequences were perceived to increase risk perceptions and promote behavioural change. Participants also reported using cognitive reframing strategies and behaviours to increase and maintain awareness of the behaviours. Overall, this study has highlighted the resistant and multi-dimensional nature of risky driving habits, as well as the situational factors that preclude them. Based on the findings, future research may benefit by focusing efforts to understanding how habituality fits in the broader deterrence literature, and how such behaviours can be best intervened.

Naturalistic observation of drivers’ hands, speed and headway

Drivers’ hands position have been shown to vary with traffic speed and complexity of the driving environment, such that drivers are more likely to place two hands on the top half of the steering wheel as the supposed driving difficulty increases (Walton, D. & Thomas, J. A. [2005]. Naturalistic observations of driver hand positions. Transportation Research Part F, 8, 229–238). This research evaluates drivers’ hands positions, examining the reliability of the measure and the relationship between the positions of the driver’s hands, vehicle speed, vehicle headway and driver sex. The findings show that the observed positions of drivers’ hands have good inter-rater reliability and demonstrate both temporal and contextual reliability. The positions of drivers’ hands are related to other measures, such that drivers with lower-ranked positions of hands are more likely to travel at higher speeds and accept shorter headways. Female drivers are found to be 2.87 times more likely than males to place two hands rather than one hand on the top half of the steering wheel.     

Differential effects of safety behaviour subtypes in social anxiety disorder

Clinical observations indicate that individuals with Social Anxiety Disorder (SAD) use a variety of safety behaviours; however, virtually no research has examined the functional effect of different safety-seeking strategies. Accordingly, we conducted two studies to address this issue. Study 1 measured global patterns of safety behaviour use in a large analogue sample. Factor analysis revealed two primary safety behaviour categories, avoidance and impression management. Study 2 assessed situational use of safety behaviours during a controlled social interaction in a clinical sample of 93 patients with Generalised SAD. Factor analysis again revealed support for avoidance and impression-management subtypes. Notably, the two types of safety behaviours were associated with different social outcomes. Avoidance safety behaviours were associated with higher state anxiety during the interaction and negative reactions from participants’ interaction partners. Impression-management strategies appeared to impede corrections in negative predictions about subsequent interactions. These findings suggest that it may be beneficial to consider the unique effects of different safety-seeking strategies when assessing and treating SAD.     

Sequential dependencies in driving

The effect of recent experience on current behavior has been studied extensively in simple laboratory tasks. We explore the nature of sequential effects in the more naturalistic setting of automobile driving. Driving is a safety-critical task in which delayed response times may have severe consequences. Using a realistic driving simulator, we find significant sequential effects in pedal-press response times that depend on the history of recent stimuli and responses. Response times are slowed up to 100 ms in particular cases, a delay that has dangerous practical consequences. Further, we observe a significant number of history-related pedal misapplications, which have recently been noted as a cause for concern in the automotive safety community. By anticipating these consequences of sequential context, driver assistance systems could mitigate the effects of performance degradations and thus critically improve driver safety.     

A meta-analysis of the association between forgiveness of others and physical health

Objective: This meta-analysis tested the relation between forgiveness of others and physical health (PH) with age, gender, race, education level, employment status, sample type, research design, type of PH variables, and publication status as the potential moderators.

Design: Eligible studies had participants with or without physical or mental health problems and had quantitative data on forgiveness of others and PH. The random-effects model was used to aggregate Fisher’s z effect sizes, which were converted back to correlation coefficients.

Main Outcome Measures: State forgiveness (forgiving an offense or offender) measures, trait forgiveness (a disposition to forgive) measures and physical health measures were included in the meta-analysis.

Results: A hundred and twenty-eight studies (N?=?58,531) were retrieved, in which the mean effect sizes showed a significant positive relationship between forgiveness of others and PH (r?=?0.14, p?<?0.001, 95% CI [0.11, 0.17]). Further, no moderators showed a significant relation between forgiveness of others and PH.

Conclusions: The positive relation between forgiveness of others and PH was not affected by potential moderators. Because the results are correlational, more forgiveness interventions may be needed to examine the causal effect of the relation between forgiveness of others and PH.     

Drivers discuss ecodriving feedback: Goal setting,framing, and anchoring motivate new behaviors

Ecodriving, defined here as the adoption of energy efficient driving styles and practices (primarily moderating accelerations and decelerations, reducing top speeds, and improved maintenance practices), has long been recognized as a potential source of reductions in transportation energy use. Estimates of energy savings attributed to ecodriving range widely, from less than 5% to as high as 20% depending on the driving and experimental context. To explore the effects on ecodriving of interaction between drivers and in-vehicle energy feedback, a customized, interactive energy feedback interface was deployed in a field test with real-world drivers. This paper presents the results of interviews with 46 Plug-in Hybrid Electric Vehicle (PHEV) drivers who were given the ecodriving feedback interface for a multi-week trial including an interface off (baseline) and on (treatment) condition. This paper relies specifically on self-reports of driver motivations and behaviors to better understand what types of information motivated new ecodriving behavior; a future paper will investigate quantitative fuel consumption effects. Driver interviews at the conclusion of the study revealed that the introduction of feedback led three fourths of drivers to change driving styles to maximize on-road efficiency, at least in the short term. In addition, this study finds that the context of the feedback information, provided by a built-in goal or other contextualizing information such as a comparison value, is important for both comprehension and motivation. Personalization of the information allowed different drivers to access pertinent information, increasing the motivational value of the information. Instantaneous performance feedback such as real-time energy economy or power is used primarily for experimentation and learning of new ecodriving behaviors, whereas average performance feedback is used primarily for goal-setting and goal achievement. In addition, the direct comparison of personalized driver goals and average performance created a game-like experience that encouraged high achievement. Finally, the driver interviews revealed that feedback frames driving as a time to act in an efficient manner.     

Measuring information demand of a dynamic in-vehicle display while driving – A study evaluating the MARS (Masking Action Relevant Stimuli) method

The MARS (Masking Action Relevant Stimuli) method assesses information demand for dynamic stimuli while driving. An action relevant stimulus is masked and the driver presses a button to unmask the stimulus for a limited period. We interpreted button presses as information demand. Following our previous research (Rittger, Kiesel, Schmidt, & Maag, 2014), the current study further evaluates the method. We applied the MARS method to a dynamic in-vehicle display containing recommendations from a traffic light assistant. In a driving simulator, drivers approached intersections with different traffic light phasing. The display either presented simple or complex information. In half of the drives, the participants used the MARS method. The study had a full within subjects design and fixations were recorded in all conditions. The results showed that the information demand varied according to the information in the display and the traffic light phase. A comparison of button presses with fixations showed that one unmasking interval came along with one fixation on the display. As a conclusion, the MARS method can distinguish between conditions with high and low information demand for the display. Button presses relate to fixations on the display. Hence, the MARS method is a promising tool to assess the information demand in dynamic environments and can be applied as an extension or alternative for eye tracking.     

Big Five personality traits and allostatic load in midlife

Objective: To examine the cross-sectional associations of Big Five personality traits with midlife allostatic load, including the role of sex, socio-demographic factors and health-related behaviours.

Design: Cross-sectional analyses of 5512 members of the Copenhagen Aging and Midlife Biobank, aged 49–63 years, 69% men.

Main outcome measure: Allostatic load (AL) based on 14 biomarkers representing the inflammatory, cardiovascular and metabolic system.

Results: Due to significant sex?×?trait interactions, analyses were stratified by sex. Openness and Conscientiousness were inversely associated with AL in both sexes, and Extraversion was positively associated with AL in men. Adjusting for socio-demographic factors significantly attenuated the association of Openness in both sexes and of Extraversion in men, for whom the inverse association of Agreeableness with AL was strengthened. Further adjusting for health-related behaviours, the Conscientiousness-AL association was attenuated but remained significant, and Agreeableness remained significantly associated with AL in men.

Conclusion: Results imply that higher levels of Agreeableness (in men) and Conscientiousness are associated with lower levels of AL above and beyond socio-demographic factors and health-related behaviours. The study further contributes by demonstrating the relevance of sex?×?trait and trait?×?trait interactions in the personality-health literature.     

Attitudes,norms and driving behaviour: A comparison of young drivers in South Africa and Sweden

Culture is increasingly recognised among traffic psychologists to be a factor influencing driving behaviour. This study examines whether a cultural background characterised by rapid social change and high levels of violence and aggression, as in the South African context, has any discernible influences on driving standards or the behaviour of individual drivers. The experiences and attitudes of young drivers in South Africa are compared with a group of young drivers from Sweden, a country whose society has exhibited high levels of stability and where road user behaviour is renowned for its restraint and compliance with regulations.The two cohorts provide information about their exposure to traffic injuries, their attitudes to other drivers and to a range of traffic offences, and to the types of behaviour they personally engage in. Among the South African respondents the notion of a declining standard of driving emerges very clearly, and specific new norms of driving are identified. Such norms are explained to be a consequence of new social values or challenges inherent within contemporary South African society.
