Assessing the effect of long-automated driving operation,repeated take-over requests,and driver’s characteristics on commercial motor vehicle drivers’ driving behavior and reaction time in highly automated vehicles

Automated Commercial Motor Vehicles (CMVs) have the potential to reduce the occurrence of crashes, enhance traffic flow, and reduce the stress of driving to a larger extent. Since fully automated driving (SAE Level 5) is not yet available, automated driving systems cannot perform all driving tasks under all road conditions. Drivers need to regain the vehicle’s control when the system reaches its maximum operational capabilities. This transition from automated to manual is referred to as Take-Over Request (TOR). Evaluating driver’s performance after TORs and assessing effective parameters have gained much attention in recent years. However, few studies have addressed CMV drivers’ driving behavior after TOR and the effect of long-automated driving and repeated TORs. This paper aims to address this gap and gain behavioral insights into CMV drivers’ driving behavior after TOR and assess the effect of the duration of automated operation before TOR, repeated TORs, and driver characteristics (e.g., age, gender, education, and driving history). To accomplish this, we designed a 40-minutes experiment on a driving simulator and assessed the responses of certified CMV drivers to TORs. Drivers’ reaction time and driving behavior indices (e.g., acceleration, velocity, and headway) are compared to continuous manual driving to measure driving behavior differences. Results showed that CMV drivers’ driving behavior changes significantly after the transition to manual regardless of the number of TORs and the duration of automated driving. Findings suggest that 30 min of automated operation intensifies the effect of TOR on driving behaviors. In addition, repeated TOR improves reaction times to TOR and reduces drivers' maximum and minimum speed after TORs. Driver’s age and driving history showed significant effects on reaction time and some driving behavior indices. The findings of this paper provide valuable information to automotive companies and transportation planners on the nature of driver behavior changes due to the carryover effects of manual driving right after automated driving episodes in highly automated vehicles.     

Are the fruits of research available to all? The effects of sex and academic rank on reprint-sending behavior

There is considerable evidence in the psychological literature that perceived status often has a major effect on behavior. The primary purpose of the present study was to examine the effects of two status variables in an academic setting by monitoring reprint-sending behavior. Reprints were requested from 1,200 authors of psychological articles by men and women of varying academic rank. Neither sex nor academic rank of requester had any significant effect on the total number of responses returned. However, male requesters received responses significantly faster than did female requesters. In addition, subsequent analyses indicated that reprint requests were more likely to be honored by male authors than by female authors.     

What makes a good driver on public roads and race tracks? An interview study

Future vehicles may drive automatically in a human-like manner or contain systems that monitor human driving ability. Algorithms of these systems must have knowledge of criteria of good and safe driving behavior with regard to different driving styles. In the current study, interviews were conducted with 30 drivers, including driving instructors, engineers, and race drivers. The participants were asked to describe good driving on public roads and race tracks, and in some questions were supported with video material. The results were interpreted with the help of Endsley’s model of situation awareness. The interviews showed that there were clear differences between what was considered good driving on the race track and good driving on the public road, where for the former, the driver must touch the limit of the vehicle, whereas, for the latter, the limit should be avoided. However, in both cases, a good driver was characterized by self-confidence, lack of stress, and not being aggressive. Furthermore, it was mentioned that the driver’s posture and viewing behavior are essential components of good driving, which affect the driver’s prediction of events and execution of maneuvers. The implications of our findings for the development of automation technology are discussed. In particular, we see potential in driver posture estimation and argue that automated vehicles excel in perception but may have difficulty making predictions.     

Is the street-crossing behavior with a head-mounted display different from that behavior in a CAVE? A study among young adults and children

The use of virtual reality (VR) has become increasingly popular in the field of traffic psychology, where realistic traffic situations can be simulated and pedestrians‘ actual crossing behavior can be studied. There are two main kinds of pedestrian simulators: one uses a technology based on rear-projection screens (Cave Automatic Virtual Environment, or CAVE); the other uses a head-mounted display (HMD). Despite their extensive use, it is yet to determine whether they are equally suitable for studying street crossing. The present study was aimed at comparing street-crossing behavior and subjective evaluations in an HMD-based (HTC vive pro) pedestrian simulator and a CAVE-like pedestrian simulator, among young adults and 12-year-old children. Thirty young adults and twenty-six children performed 36 street-crossing trials (combining different speeds, traffic conditions, and gap sizes) on each of the two simulators. The results indicated that, compared to the CAVE-condition participants, HMD-condition participants accepted more crossing trials (hence, shorter gaps), initiated their crossings sooner, crossed at a slower speed, had shorter safety margins, and caused more collisions. The main difference between the two devices was in crossing initiation, which occurred markedly earlier (1.72 s) with the HMD than in the CAVE: the perception–action coupling was less finely tuned in the CAVE, probably because visual information in front of the pedestrian was missing due the absence of ground projection and 3D rendering. A significant effect of vehicle-approach speed was observed for both devices, with more unsafe behaviors at 60 km/h than at 40 km/h. Children displayed riskier crossing behavior than young adults did, with more accepted crossings, slower crossing speeds, shorter safety margins, and higher collision rates, especially in the HMD. Compared to the CAVE, the HMD received higher ratings for level of presence and a preference for VR, but also higher simulator-sickness scores. No adverse effects of exposure to virtual reality was found on stereoacuity or postural balance. The suitability of using CAVE and HMD simulators is discussed, especially for studying child pedestrians.     

Are anxiety and depression just as stable as personality during late adolescence? Results from a three-year longitudinal latent variable study

Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression. Comparison of various representations of a latent variable trait-state-occasion (TSO) model revealed that whereas the full TSO model was the best representation for depression, a trait stability model was the most parsimonious of the best-fitting models for the anxiety and personality constructs. Over three years, the percentages of variance explained by the trait component for the anxiety and personality constructs (73-84%) were significantly greater than that explained by the trait component for depression (46%). These findings indicate that symptoms of depression are more episodic in nature, whereas symptoms of anxiety are more similar to personality variables in their expression of stability.     

Does intergroup contact affect personality? A longitudinal study on the bidirectional relationship between intergroup contact and personality traits

We conducted a longitudinal study to test whether, in addition to being predicted by personality, intergroup contact is longitudinally associated with personality traits. Participants were 388 majority (Italian) and 109 minority (immigrant) first‐year high school students. Results revealed a bidirectional relationship between contact and personality: Quality of contact was longitudinally associated with greater agreeableness and openness to experience, whereas agreeableness and openness to experience were longitudinal predictors of contact quality. An unexpected negative longitudinal association also emerged between quantity of contact and agreeableness. These effects were not moderated by group of belonging (majority vs. minority). Our findings highlight the importance of integrating research on intergroup contact with research on personality.     

Bad for me or bad for us? Interpersonal orientations and the impact of losses on unethical behavior

The present research examines the role of allocations of losses versus gains on the emergence of unethical behavior as a function of people's social value orientation. The authors demonstrate that (a) proselfs regard unethical behavior to prevent losses as more justified than prosocials (Study 1) and (b) proselfs engage in more unethical behavior to prevent losses than prosocials (Study 2). These differences are explained by prosocials' greater concern for harm to interdependent others in the domain of losses. A third study further substantiates these findings by revealing that unethical behavior to prevent losses increases among prosocials as harm to others is reduced. In sum, these results reveal that depending on whether people attend only to their self-interest or also consider the outcomes of others, losses either may increase or curtail unethical conduct. Considering social value orientations thus may reconcile conflicting theoretical perspectives on the impact of losses on social decisions.     

Are you tired? Spillover and crossover effects of emotional exhaustion on the family domain

This paper examines the spillover and crossover effects of emotional exhaustion on marital satisfaction for both employees and partners as well as on employee work–family conflict and partner family–work conflict. It investigates how the transmission of psychological strain from the workplace to the family domain mediates these relationships. In a sample of 226 employee–partner dyads from manufacturing, electronics, banking, service industries and public organizations, the results support the notion that employees' emotional exhaustion spawns negative strain in the home. More specifically, the results of spillover mediation analyses show the relationships between emotional exhaustion and employee marital satisfaction/work–family conflict in the home. In a crossover model, the results indicate that employee psychological strain mediates the relationships between emotional exhaustion and the marital satisfaction of partners/family–work conflict in partners. These findings provide supports for spillover and crossover models to investigate a direction for the effectiveness of emotional exhaustion on family issues. Theoretical and practical implications of the results are discussed, and directions for future research are offered.     

Drinking and driving “safely”: Who uses a breathalyzer and when?

Breathalyzers are often promoted on the grounds of safety. However, drivers who use them to avoid illegal blood-alcohol levels inadvertently expose themselves to sleepiness-related risks following alcohol intake. Personal breathalyzers may even be counterproductive if they make more drivers engage in more frequent or habitual drinking and driving. This study explores the extent to which and how drivers use the breathalyzer. We contacted nine major breathalyzer importers in Finland and found out that the estimated number of devices delivered during 2006 was almost 50,000, equaling approximately one percent of population and one-and-a-half percent of driving-license holders. Survey data on a representative sample of Finnish active drivers (N = 1121) showed that 11.5% owned a breathalyzer. More men than women own and use a breathalyzer, and most often the men are aged 36–55 years. These men also use it more often after acute drinking (32% vs. 20% in the whole sample). Seventy-nine percent of breathalyzer use occurs the following day after evening or night drinking. Therefore, while in a smaller percentage of cases the risk involves the additive and interactive effects of alcohol and sleepiness in the evening, most users expose themselves to risks related to daytime sleepiness due to drinking the previous night.     

Orientations and motivations: Are you a “people person,” a “thing person,” or both?

Previous theory and research suggests that individuals selectively orient primarily toward the social environment (people) or toward the physical environment (things). These orientations can be conceptualized as motivation-based complexes that influence personal preferences and interests, with consequences for important life choices. This paper examined differential orientation in two studies, one with university students and another with children. Person-thing Orientation showed sex differences and was related to occupational choices in both age groups. For university students person-thing interests were linked to academic majors, and retention within programs focused on things (e.g., science and engineering). Sex differences were greater for TO than PO, but not for students majoring in engineering. Sex differences in selective orientations to the social and physical environments were similar in children (3rd and 6th grade) and university students, suggesting processes may be underway early and may be consequential for sex differences in interests and career trajectories for STEM.     

“Don’t you know I own the road?” The link between narcissism and aggressive driving

Aggressive drivers can make driving dangerous. Over 50% of traffic fatalities are caused by aggressive driving. This research tests whether narcissists are more aggressive drivers than other individuals. Narcissists think they are special people who deserve special treatment. When they don’t get the special treatment they think they deserve, narcissists often lash out at others in an aggressive manner. Narcissists might think they “own the road” and can drive anyway they want, and that other drivers should get out of their way. In the article, we conduct three studies to test the link between narcissism and aggressive driving. In Studies 1 (N = 139) and 2 (N = 100), Luxembourgish motorists completed a measure of narcissism and a self-report measure of aggressive driving. In Study 3 (N = 60), American university students completed a measure of narcissism and then completed a driving simulation scenario that contained a number of frustrating elements. Several measures of aggressive driving and road rage were obtained. In all three studies, narcissism was positively related to aggressive driving. A meta-analysis found an average correlation of r = 0.35 across the three studies. This research replicates previous research linking narcissism to aggression, and extends it to a driving context.     

Are you afraid of the dark? Notes on the psychology of belief in histories of science and the occult

Abstract

The popular view of the inherent conflict between science and the occult has been rendered obsolete by recent advances in the history of science. Yet, these historiographical revisions have gone unnoticed in the public understanding of science and public education at large. Particularly, reconstructions of the formation of modern psychology and its links to psychical research can show that the standard view of the latter as motivated by metaphysical bias fails to stand up to scrutiny. After highlighting certain basic methodological maxims shared by psychotherapists and historians, I will try to counterbalance simplistic claims of a ‘need to believe’ as a precondition of scientific open-mindedness regarding the occurrence of parapsychological phenomena by discussing instances revealing a presumably widespread ‘will to disbelieve’ in the occult. I shall argue that generalized psychological explanations are only helpful in our understanding of history if we apply them in a symmetrical manner.     

Are all “research fields” equal? Rethinking practice for the use of data from crowdsourcing market places

New technologies like large-scale social media sites (e.g., Facebook and Twitter) and crowdsourcing services (e.g., Amazon Mechanical Turk, Crowdflower, Clickworker) are impacting social science research and providing many new and interesting avenues for research. The use of these new technologies for research has not been without challenges, and a recently published psychological study on Facebook has led to a widespread discussion of the ethics of conducting large-scale experiments online. Surprisingly little has been said about the ethics of conducting research using commercial crowdsourcing marketplaces. In this article, I focus on the question of which ethical questions are raised by data collection with crowdsourcing tools. I briefly draw on the implications of Internet research more generally, and then focus on the specific challenges that research with crowdsourcing tools faces. I identify fair pay and the related issue of respect for autonomy, as well as problems with the power dynamic between researcher and participant, which has implications for withdrawal without prejudice, as the major ethical challenges of crowdsourced data. Furthermore, I wish to draw attention to how we can develop a “best practice” for researchers using crowdsourcing tools.     

Are we puppets on a string? Comparing the impact of contingency and validity on implicit and explicit evaluations

Research has demonstrated that implicit and explicit evaluations of the same object can diverge. Explanations of such dissociations frequently appeal to dual-process theories, such that implicit evaluations are assumed to reflect object-valence contingencies independent of their perceived validity, whereas explicit evaluations reflect the perceived validity of object-valence contingencies. Although there is evidence supporting these assumptions, it remains unclear if dissociations can arise in situations in which object-valence contingencies are judged to be true or false during the learning of these contingencies. Challenging dual-process accounts that propose a simultaneous operation of two parallel learning mechanisms, results from three experiments showed that the perceived validity of evaluative information about social targets qualified both explicit and implicit evaluations when validity information was available immediately after the encoding of the valence information; however, delaying the presentation of validity information reduced its qualifying impact for implicit, but not explicit, evaluations.     

Are you willing to pay the price? The impact of corporate social (ir)responsibility on consumer behavior towards national and foreign brands

This research examines how the country of origin (national vs. foreign) affects the relation between corporate social responsibility (CSR) and consumers' willingness to pay and purchase intention. In the study, we adopted a first‐price sealed bid auction approach, using money in a “real‐world” setting. The results showed that CSR/corporate social irresponsibility (CSIR) affects consumer behavior and, particularly, consumers' willingness to pay and purchase intention. The study supports both the moderation hypothesis of country of origin in the relationship between CSR/CSIR and willingness to pay and between CSR/CSIR and purchase intention. In the globalization context, these results have important implications for brands' communication and marketing strategy and can stimulate important insights in organizations. Future research directions and limitations are also discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

A quantitative review of the relations between the “Big 3” higher order personality dimensions and antisocial behavior

In this meta-analytic review, Hans J. Eysenck’s theory of criminality (Eysenck, 1964, Eysenck, 1977) serves as a theoretical framework for examining the relations between higher order personality dimensions and antisocial behavior (ASB). The three higher order dimensions examined are referred to as extraversion/sociability, neuroticism/emotionality, and impulsivity/disinhibition (see Sher & Trull, 1994), and they are likened to Eysenck’s dimensions of extraversion (E), neuroticism (N), and psychoticism (P), respectively (Eysenck & Eysenck, 1975) and Tellegen’s dimensions of positive emotionality (PEM), negative emotionality (NEM), and constraint (reversed) (CON), respectively (Tellegen, 1982). Ninety-seven samples, from 52 published and unpublished studies, were reviewed. The results indicated that among the “Big 3” personality dimensions, impulsivity/disinhibition is most strongly related to ASB and extraversion/sociability is least strongly related to ASB. Additional variables, including age and methodological differences, were found to moderate the associations between the personality dimensions and ASB.     

Are parenting practices associated with the development of narcissism? Findings from a longitudinal study of Mexican-origin youth

Narcissism is an important and consequential aspect of personality, yet we know little about its developmental origins. Using data from a longitudinal study of 674 Mexican-origin families, we examined cross-lagged relations between parenting behaviors (warmth, hostility, monitoring) and narcissism (superiority, exploitativeness). Parental hostility at age 12 was associated with higher levels of exploitativeness at age 14, whereas parental monitoring at age 12 was associated with lower levels of exploitativeness at age 14. These effects replicated across three different parenting measures: child reports, spouse reports, and behavioral coding of parent-child interactions. None of the parenting dimensions was related to superiority, suggesting that parenting practices are more strongly related to the maladaptive than the adaptive component of narcissism.     

Between you and God,where is the general factor of personality? Exploring personality-religion relationships in a Muslim context

Personality-religiosity links were studied in a Muslim population. Agreeableness and Conscientiousness were generally the strongest correlates of religiousness. Evidence for the general factor of personality (GFP) was found in analyses of correlations among scores on the Big Five, in four studies (total N = 1000). Also, a GFP was positively correlated with gratitude to God, interest in religion, intrinsic religiosity and extrinsic-personal religiosity, but not extrinsic-social religiosity. Results demonstrated cross-cultural consistency of the GFP, and its relationship with a variety of religious constructs.     

Does a person selectively recall the good or the bad from their personal past? It depends on the recall target and the person’s favourability of self-views

In three studies, participants remembered real-life behaviours at Time 1 and attempted to recall them at Time 2. When the recall target was the self, a positivity bias emerged: self-positivity. In Study 3, self-positivity extended to an individual (target) who was liked by the participant, but did it not extend to a disliked target. For this latter target, a negativity bias emerged. For recall targets that were participants’ acquaintances, self-positivity in recall was also eliminated in Studies 1 and 3, and a negativity bias in recall emerged in Study 2. Finally, in Study 2 (but not Study 3), the favourability of participants’ self-view predicted the magnitude of the self-positivity in self-recall, but it did not predict valence effects in other-recall. Taken together, the results indicate that the link between behaviour valence and recall is moderated by the recall target and the favourability of one’s self-view.
