Signal detection in conditions of everyday life traffic dilemmas

This paper shows how the paradigm of signal detection could serve as a viable means for the analysis of drivers’ choices in conditions of everyday life traffic dilemmas. The participants were 28 drivers, most of them professional, who spend at least 6 h a day on the road. All agreed to have a note-taking silent passenger for the entire journey, every day during a period of 3–4 weeks. All completed the sensation-seeking questionnaire. Their ‘to do or not to do’ choices in conditions of four (out of a total of six) traffic dilemmas (amber light, distance keeping, stopping in road-crossing and merging in routes) were analyzable in terms of a modification of the paradigm of signal detection. In accord with the basics of the paradigm of signal detection, the rate of success of the drivers to detect signals of danger on the road (perceptual sensitivity) fell into the range of partial uncertainty (more than 50% and not too much above this level)! The choices made by thrill-and-adventure-seeking drivers were more lenient than the choices of the drivers who scored lower on this dimension.     

Finding the daredevils: development of a Sensation Seeking Scale for children that is relevant to physical risk taking

OBJECTIVE: There were two objectives in this research. First, to develop and evaluate the criterion validity of a questionnaire measure of sensation seeking in children, by examining how scores on this instrument relate to various indices of physical risk taking in children 7-12 years of age. Second, to develop both a parent-report and child-report version of the instrument. METHODS: Drawing on the literature, items tapping five potential aspects of sensation seeking were developed, with parents and children responding to comparable items. For each of these five subscales, internal reliability estimates were computed separately for the parent-report and child-report versions. To establish criterion validity, subscale scores were related to three indices of children's risk taking commonly used in research: actual risk taking, intentions-to-risk take, self-reports about risk taking on a standardized questionnaire. RESULTS: On both the child-report and parent-report versions, the same three of the five subscales yielded acceptable internal reliability scores and significantly related to the various indices of risk taking. CONCLUSIONS: This new measure adequately assesses aspects of sensation seeking relevant to children's risk taking. Because individuals high in sensation seeking engage in greater risk taking and are at increased risk of injury, this instrument may prove particularly useful to aid in identifying those children most likely to engage in injury-risk behaviors so that targeted interventions can be applied to this group.     

Early identification of children at risk of unintentional injury: A sensation seeking scale for children 2-5 years of age

Objective

Sensation seeking is a personality attribute associated with injury in school-age children, adolescents, and adults. This study aimed to develop and evaluate the psychometric properties of a questionnaire measure of sensation seeking for young children 2-5 years of age.

Methods

Items tapping aspects of sensation seeking (Novelty Seeking, Behavioral Intensity, Thrill Seeking) were developed, content validation was completed by child development experts, and 72 parents then completed the Sensation Seeking Scale for Young Children (SSSYC) twice (3 months intervening) to establish internal and test-retest reliabilities. To assess criterion validity, scores were related to children's preferences for high versus low sensation seeking activities, their free play behavior in an indoor playroom, and to children's history of unintentional injuries.

Results

Indices of internal reliability and test-retest reliability were good and questionnaire scores positively correlated with sensation seeking behaviors during free play, preferences for high versus low sensation seeking activities, and injury measures, providing support for criterion validity.

Conclusion

This initial evaluation of the SSSYC suggests that it is a psychometrically sound measure of sensation seeking. This scale may be useful for identifying high sensation seekers at young ages, providing the opportunity for early intervention to prevent unintentional injuries.     

Speeding for fun? Exploring the speeding behavior of riders of heavy motorcycles using the theory of planned behavior and psychological flow theory

This paper focuses on a special segment of motorcyclists in Taiwan – riders of heavy motorcycles – and investigates their speeding behavior and its affecting factors. It extends the theory of planned behavior (TPB) to explore motorcyclist speeding behavior by including the variables of psychological flow theory. The levels of sensation-seeking and riding experience are also used as grouping variables to investigate group differences from the influences of their affecting factors on speeding behavior. The results reveal that the psychological flow variables have greater predictive power in explaining speeding behavior than the TPB variables, providing useful insights into the unique nature of this group of motorcyclists, who are more prone to engage in speeding. Group differences with regard to both sensation-seeking and rider experience in speeding behavior are highlighted, and the implications of the findings are discussed.     

Alcohol-impaired driving behavior and sensation-seeking disposition in a college population receiving routine care at campus health services centers

Accidents stemming from alcohol-impaired driving are the leading cause of injury and death among college students. Research has implicated certain driver personality characteristics in the majority of these motor vehicle crashes. Sensation seeking in particular has been linked to risky driving, alcohol consumption, and driving while intoxicated. This study investigated the effect of sensation seeking on self-reported alcohol-impaired driving behavior in a college student population while adjusting for demographics, residence and drinking locations. A total of 1587 college students over the age of 18 completed a health screening survey while presenting for routine, non-urgent care at campus heath services centers. Student demographics, living situation, most common drinking location, heavy episodic drinking, sensation-seeking disposition and alcohol-impaired driving behavior were assessed. Using a full-form logistic regression model to isolate sensation seeking after adjusting for covariates, sensation seeking remains a statistically significant independent predictor of alcohol-impaired driving behavior (OR = 1.52; CI = 1.19-1.94; p < 0.001). Older, white, sensation-seeking college students who engage in heavy episodic drinking, live off-campus, and go to bars are at highest risk for alcohol-impaired driving behaviors. Interventions should target sensation seekers and environmental factors that mediate the link between sensation seeking and alcohol-impaired driving behaviors.     

Sensation seeking and drunk driving: The mediational role of social norms and self-efficacy

The aim of this work was to examine the role of sensation seeking in drunk driving by youths, and the potential mediational effect of social, cognitive and emotional variables on their relationship. To this end, a survey was conducted on 274 drivers (164 females and 110 males) aged 24.36 ± 2.96 years (range 18–30 years). The results obtained confirm the significance of sensation seeking to drunk driving by youths and the mediating role of biased self-efficacy perceptions in their relationship. The important practical implications of this finding on the development of effective interventions to prevent the risks of drunk driving in youths are discussed.     

Risky and aggressive driving in young adults: Personality matters

Young, novice drivers constitute a disproportionate percentage of fatalities and injuries in road traffic accidents around the world. This study, attempts to identify motivational factors behind risky driving behavior, and examines the role of personality, especially sensation seeking, impulsivity and sensitivity to punishment/reward in predicting negative driving outcomes (accident involvement and traffic offences) among young drivers. Gender and driver's age are additional factors examined in relation to driving outcomes and personality. Adopting the contextual mediated model of traffic accident involvement (Sümer, 2003), the study is based on the theory that personality, age and gender represent distal factors that predict accident involvement indirectly through their relationship with stable tendencies towards aberrant driving behavior. Results from correlations and Structural Equation Modeling using AMOS 6 indicated that direct personality effects on driving outcomes were few, whereas personality had significant correlations with aberrant driving behavior, showing that personality is a distal but important predictor of negative driving outcomes. These high risk traits appear to be at a peak among young male drivers. Thus, personality is important in understanding aggressive and risky driving by young adults and needs to be taken into consideration in designing targeted accident prevention policies.     

Sensation seeking and detection of risky road signals: a developmental perspective

The relevance of the construct of sensation seeking, particularly the motivation to seek thrill and adventure and to avoid boredom, to detection of danger on the road, in particular choices made in conditions of road dilemmas (e.g. road-crossing and amber-light), was examined. 412 participants, males and females, from three age groups--7, 13 and 22--completed Zuckerman's test of sensation seeking and were exposed to the following experiments: Virtual driving, road crossing and go-carting. In each experiment, participants were exposed individually to a series of road dilemmas, constructed according to the paradigm of signal detection. In each dilemma, a dichotomous choice was made: To do or not to do. Age- and gender-dependent responses and connections were obtained. Most noticeable is a risky shift in males' detection responses and an inverse trend in females.     

Thrill and Adventure Seeking as a modifier of the relationship of perceived risk with risky driving among young drivers

Risky driving contributes to road trauma, a leading cause of mortality among young people. Health-relevant behaviour models suggest a negative relationship between risky driving and perceived risk of its outcomes. However, high sensation seekers may value the “thrill” of the risk, and positive associations between sensation seeking and risky driving have been observed. This is the first study to examine whether aspects of sensation seeking modify the relationship between perceived risk and risky driving. Young drivers in metropolitan Sydney and rural New South Wales [NSW] (n = 797) completed a survey relating to one of the four risky driving behaviours (speeding, drink-driving, driving while fatigued, and failing to wear a seatbelt). Results suggest that the Thrill and Adventure Seeking subscale of Zuckerman's (1994) Sensation Seeking Scale moderate the relationship of perceived risk with risky driving – indicating a negative relationship for low-scores, but not high-scorers, on the TAS subscale. Thus, road safety campaigns that emphasize the riskiness of a particular behaviour may be of limited benefit to thrill and adventure seekers.

Increased patterns of risky behaviours among helmet wearers in skiing and snowboarding

Background

There has been an ongoing debate as to whether wearing helmets in skiing and snowboarding increases the risk tolerance of participants.

Objective

To investigate the roles of demographic and personality variables, and helmet usage in predicting risk taking behaviours in a cross-sectional sample of intermediate and proficient skiers and snowboarders.

Methods

Risk taking in skiing was measured using a validated 10-item self-report measure which was designated as the outcome variable in a three step hierarchical regression. Independent predictors included age, sex, education, sport, ability, helmet usage, and personality traits that have been associated with risk taking: impulsivity and sensation seeking.

Results

In the final regression model, helmet use significantly predicted variance in risk taking (standardized β = .10, p = .024), and the relationship remained after accounting for variance due to demographic variables and general trait measures. The partial relationship between risk taking and sex, ability, impulsivity, and sensation seeking were also significant (p < .05).

Conclusion

High sensation seeking, high impulsivity, male sex, and proficiency were associated with increased patterns of risky behaviours in skiers and snowboarders, and after accounting for these factors, helmet use was a significant predictor of risk taking. The relationship between helmet use and risk taking was modest suggesting that the costs of increased risk taking is not likely to outweigh the protective benefits of a helmet.     

Risky attitudes towards road use in pre-drivers

Motor vehicle accidents are one of the principal causes of adolescent disability or mortality and male drivers are more likely to be involved in road accidents than female drivers. In part such associations between driver age and sex have been linked to differences in risky behaviour (e.g. speed, violations) and individual characteristics (e.g. sensation seeking, deviant behaviour). The aim of this research is to determine whether associations between risky road user behaviour and individual characteristics are a function of driver behaviour or whether they are intrinsic and measurable in individuals too young to drive.

Five hundred and sixty-seven pre-driver students aged 11–16 from three secondary schools completed questionnaires measuring enthusiasm for speed, sensation seeking, deviant behaviour and attitudes towards driver violations. Boys reported more risky attitudes than girls for all measures. Associations between sensation seeking, deviant behaviour and attitudes towards risky road use were present from early adolescence and were strongest around age 14, before individuals learn to drive.

Risky attitudes towards road use are associated with individual characteristics and are observed in adolescents long before they learn to drive. Safe attitudes towards road use and driver behaviour should be promoted from childhood in order to be effective.     

Validation of the Chinese-language brief sensation seeking scale: Implications for risky riding behaviors of parental motorcyclists and their child passengers

Motorcycles are the leading cause of road traffic deaths in the Western Pacific and Southeast Asia, where Mandarin Chinese is the most commonly used language. Sensation seeking (SS) is reported to correlate with many risky motor vehicle behaviors, and therefore a culture-adapted Chinese instrument is needed to assess this personality trait in Chinese-speaking motorcycling populations. The standard front and blinded-backward process was carried out to formulate the Chinese-language Brief Sensation Seeking Scale (C-BSSS). 193 parental motorcyclists who rode with their young children were interviewed concerning their SS levels, demographics, riding behaviors, and the driving/riding experiences. A random sample of 30 subjects was re-interviewed 1–2 weeks later to examine the test-retest reliability. Psychometric analyses revealed satisfactory item characteristics, internal consistency, intraobserver reliability, and interobserver reliability. Additionally, parental motorcyclists who had the following characteristics were more likely to be the high sensation seekers (SSers), including male, younger age, presenting risky motor vehicle behaviors of themselves (e.g., higher riding speeds, operating after drinking, using a mobile phone while operating, and receiving a traffic ticket), and carrying child passengers who demonstrated dangerous motorcycling behaviors (e.g., a younger age, non-helmeted, and overloaded). We conclude that the C-BSSS is a useful and reliable measure of SS for ethnic Chinese populations. This instrument may be helpful to develop the future prevention strategy of motorcycle injuries in Chinese parental motorcyclists and their young child passengers.     

Understanding risk compensation in children: Experience with the activity and level of sensation seeking play a role

The aims of this study were to determine if children 7–12 years show risk compensation when engaging in ecologically valid recreational sports tasks, and to explore how experience with the activity and extent of sensation seeking influence this. Children were positioned up on a platform, on a bike or wearing rollerblades, and they were presented varying heights and inclines from which they selected the greatest one they go down when wearing and not wearing safety gear appropriate to the activity; when making their ratings they anticipated actually doing the task. Results revealed that children engaged in significantly more risk taking when wearing safety gear, thereby demonstrating risk compensation, and this was significantly greater for the activity with which they had greater experience. However, children high in sensation seeking demonstrated significantly more risk compensation in both the high and low experience activities, although the injury risk appraisals that predicted risk compensation varied with experience level. Implications for the design of injury prevention programs and directions for future research are discussed.     

Motor ability: protective or risk for school injuries?

The study aims were to assess the independent contribution of motor ability to the incidence of school injuries. The study included 2057 pupils in grades 3-6 of primary schools in a city in the north of Israel. A surveillance system gathered information about injuries that occurred on school premises or during school related activities and required medical treatment or caused limitation of usual activities. Children provided information on sensation seeking, self-appraisal of health, academic performance, physical activity, and dominant hand; anthropometric measurements and motor ability tests were performed.The incidence of injury events was 4% (95% CI=3.2-5.0). Injuries increased with increased balance and agility, but there were no differences according to reaction time. No other study variables were associated with the incidence of injuries. Our findings of an increase in the incidence of injuries with better motor ability may express differences in exposure to risk situations between children with better and poorer motor abilities.     

The effect of stress and personality on dangerous driving behavior among Chinese drivers

The relationship between stress and road safety has been studied for many years, but the effect of global stress and its joint effect with personality on driving behavior have received little attention in previous studies. This study aimed to elucidate the impact of global stress and various personality traits on driving behavior. 242 drivers completed the Perceived Stress Scale-10 (PSS-10), the Dula Dangerous Driving Index (DDDI), and several personality trait scales related to anger, sensation seeking, and altruism. The results showed that perceived stress and sensation seeking were significantly correlated with the four subcategories of dangerous driving behavior, namely, negative cognitive/emotional driving (NCED), aggressive driving (AD), risky driving (RD), and drunk driving (DD). Moreover, anger was positively correlated with negative cognitive/emotional driving, aggressive driving, and risky driving, and altruism was negatively correlated with aggressive driving and drunk driving. Hierarchical multiple regressions were applied to analyze the mediating effect of personality traits, and the results showed that anger mediated the relationship between stress and dangerous driving behavior and that this mediating role was especially strong for negative cognitive/emotional driving and aggressive driving. Collectively, the results showed that stress is an important factor that can affect people's driving behavior but that personality traits mediate the effect of stress on driving behavior. The findings from this study regarding the relationship among stress, anger, and dangerous driving behavior could be applied in the development of intervention programs for stress and anger management in order to improve drivers’ ability to manage emotional thoughts and adjust their behavior on the road.     

Parents’ and peers’ contribution to risky driving of male teen drivers

The current study joins efforts devoted to understanding the associations of parents’ personality, attitude, and behavior, and to evaluating the added contribution of peers to the driving behavior of young drivers during their solo driving. The study combines data gathered using in-vehicle data recorders from actual driving of parents and their male teen driver with data collected from self-report questionnaires completed by the young drivers. The sample consists of 121 families, who participated in the study for 12 months, beginning with the licensure of the teen driver. The current examination concentrates on the last 3 months of this first year of driving. The experimental design was based on a random control assignment into three treatment groups (with different forms of feedback) and a control group (with no feedback). Findings indicate that the parents’ (especially the fathers’) sensation seeking, anxiety, and aggression, as well as their risky driving events rate were positively associated with higher risky driving of the young driver. In addition, parents’ involvement in the intervention, either by feedback or by training, led to lower risky driving events rate of young drivers compared to the control group. Finally, higher cohesion and adaptability mitigated parents’ model for risky driving, and peers norms’ of risky driving were associated with higher risk by the teen drivers. We conclude by claiming that there is an unequivocal need to look at a full and complex set of antecedents in parents’ personality, attitudes, and behavior, together with the contribution of peers to the young drivers’ reckless driving, and address the practical implications for road safety.     

A further exploration of sensation seeking propensity,reward sensitivity,depression, anxiety,and the risky behaviour of young novice drivers in a structural equation model

Young novice drivers constitute a major public health concern due to the number of crashes in which they are involved, and the resultant injuries and fatalities. Previous research suggests psychological traits (reward sensitivity, sensation seeking propensity), and psychological states (anxiety, depression) influence their risky behaviour. The relationships between gender, anxiety, depression, reward sensitivity, sensation seeking propensity and risky driving are explored. Participants (390 intermediate drivers, 17–25 years) completed two online surveys at a six month interval. Surveys comprised sociodemographics, Brief Sensation Seeking Scale, Kessler's Psychological Distress Scale, an abridged Sensitivity to Reward Questionnaire, and risky driving behaviour was measured by the Behaviour of Young Novice Drivers Scale. Structural equation modelling revealed anxiety, reward sensitivity and sensation seeking propensity predicted risky driving. Gender was a moderator, with only reward sensitivity predicting risky driving for males. Future interventions which consider the role of rewards, sensation seeking, and mental health may contribute to improved road safety for younger and older road users alike.
