Investigation of drivers’ thresholds of a subjectively accepted driving performance with a focus on automated driving

Lately, the development and implementation of automated driving moved to the center of interest in the automotive industry. In this context, one of the central issues – the configuration of adequate trajectories – is mainly tackled using a technical approach. However, it appears that a technically ideal driving performance does not necessarily coincide with the drivers’ subjective preferences. This study strives to determine thresholds of a subjectively accepted driving performance regarding lateral vehicle control. A second objective is to analyze the influence of selected personal and situational factors on these thresholds. An empirical online survey with 161 participants rating video sequences of driving performances was conducted. The video sequences differed not only with regard to the lateral offset of the ego-vehicle but also concerning the weather (sun/rain) and traffic conditions (existence/driving behavior of oncoming traffic). Additionally, the participants’ driving experience and sensation seeking were considered in the data evaluation. To analyze the data, binary logistic regression analyses were calculated. They revealed that the subjective evaluation of driving performances varies primarily depending on the lateral offset of both the ego-vehicle and the oncoming traffic. The results indicate that regarding the lateral offset certain thresholds of subjectively accepted driving performances do exist. Regarding the development of automated driving systems, two issues need to be considered in order to ultimately guarantee user acceptance. First, the subjective thresholds need to be integrated into the systems’ trajectory planning. Second, the oncoming traffic’s driving behavior has to be considered.     

Evaluation of user behavior and acceptance of an on-bike system

In this study, users’ acceptance of an on-bike system that warns about potential collisions with motorized vehicles as well as its influence on cyclists’ behavior was evaluated. Twenty-five participants took part in a field study that consisted of three different experimental tasks. All participants also completed a follow-up questionnaire at the completion of the three-task series to elicit information about the acceptance of the on-bike system. In the experiment phase, participants were asked to ride the bicycle throughout a circuit and to interact with a car at an intersection. Participants completed three laps of the circuit. The first lap involved no interaction with the car and served the purpose of habituation. In the second and third laps participants experienced a conflict with an incoming car at an intersection. In the second lap, the on-bike device was not activated, while in the third lap, participants received a warning message signaling the imminent conflict with the car. We compared the difference in user’s behavior between the second lap (conflict with a car without the warning of the on-bike system) and the third lap (conflict with a car with the warning of the on-bike system). Results showed that, when entering the crossroad, participants were more likely to decrease their speed in case of warning of the on-bike system. Further, the on-bike system was relatively well accepted by the participants. In particular, participants did not report negative emotions when using the system, while they trusted it and believed that using such technology would be free from effort. Participants were willing to spend on average 57.83 € for the system. This study highlights the potential of the on-bike system for promoting bicycle safety.     

Experiential Avoidance: An Examination of the Construct Validity of the AAQ-II and MEAQ

Experiential avoidance (also referred to as acceptance or psychological flexibility) is a core construct of third-wave behavior therapies. It is the tendency to avoid uncomfortable thoughts or feelings, even when doing so has negative long-term consequences. In order for developments in experiential avoidance and third-wave behavior therapies to continue, it is imperative to examine the construct validity of the most widely used measures of this construct, the Acceptance and Action Questionnaire–II (AAQ-II) and the Multidimensional Experiential Avoidance Questionnaire (MEAQ). In Amazon’s Mechanical Turk (N = 1,052) and college (N = 364) samples, we evaluated the construct validity of these measures. The AAQ-II demonstrated suboptimal patterns of convergent and discriminant validity with measures of neuroticism/negative affect (Big Five Inventory, Big Five Aspects Scale, Positive and Negative Affect Schedule), the MEAQ, and mindfulness (Five Factor Mindfulness Questionnaire). In contrast, the MEAQ demonstrated optimal convergent and discriminant validity. Factor analyses at the scale, subscale, and item levels demonstrated that the AAQ-II loads with indicators of neuroticism/negative affect and not with other constructs at the core of third-wave behavior therapies. In contrast, the MEAQ loads on factors with mindfulness or forms its own factors. These findings suggest the AAQ-II functions as a measure of neuroticism/negative affect, whereas the MEAQ functions as an indicator of experiential avoidance. These findings have substantial implications for research on experiential avoidance and third-wave behavior therapies. Therefore, in order to improve the theory, research, and practice of third-wave behavior therapies, we recommend using the MEAQ to assess experiential avoidance.     

When is a lie acceptable? Work and private life lying acceptance depends on its beneficiary

In this article we show that when analyzing attitude towards lying in a cross-cultural setting, both the beneficiary of the lie (self vs other) and the context (private life vs. professional domain) should be considered. In a study conducted in Estonia, Ireland, Mexico, The Netherlands, Poland, Spain, and Sweden (N = 1345), in which participants evaluated stories presenting various types of lies, we found usefulness of relying on the dimensions. Results showed that in the joint sample the most acceptable were other-oriented lies concerning private life, then other-oriented lies in the professional domain, followed by egoistic lies in the professional domain; and the least acceptance was shown for egoistic lies regarding one’s private life. We found a negative correlation between acceptance of a behavior and the evaluation of its deceitfulness.     

Academic goals and learning strategies in secondary education Spanish students with social anxiety / Metas académicas y estrategias de aprendizaje en estudiantes españoles de Educación Secundaria Obligatoria con ansiedad social

The purpose of this study was to analyse the relationship between high social anxiety, academic goals and learning strategies in a sample of 2,022 (51.1% male) Spanish adolescents aged 12–16. The Social Phobia and Anxiety Inventory (SPAI), Achievement Goal Tendencies Questionnaire (AGTQ) and Learning and Studies Skills Strategies Inventory — High School Version (LASSI-HS) were used to assess the variables. The results showed no statistically significant differences in goal orientations between students with and without high social anxiety. However, students with high social anxiety used learning strategies significantly less. In addition, the logistic regression results indicated that high social anxiety acts as a significant predictor for setting social reinforcement goals and learning and study strategies.     

CROSSING THE DIVIDE: LESSONS FROM DEVELOPING WIND ENERGY IN POST‐FACT AMERICA

The income and careers that come with building wind turbines have become a lifeline for many factory towns and farming communities. Generating electricity from the wind puts increasingly cheap power on the grid, saving consumers billions a year. And it is one of the biggest, fastest, cheapest ways to reduce carbon pollution, reducing the threat of climate change. Yet as wind farms have rapidly spread to forty‐one states, their developers must make their case anew with each community that hosts them. Facts matter, but so do empathy, honoring deep connections to neighbors and landscape, and developing mutual respect. Successful wind farm developers listen first for shared values and speak with inclusive language, to communicate with potential opponents across divides of misunderstanding and motivate local residents to adapt to and benefit from change.     

When the Going Gets Tough,the Differentiated Keep Going: Cybernetic Self-Determination,Daily Obstacles,and Persistent Goal Pursuit

ABSTRACT. Cybernetic theories of self-regulation contend that an individual's goal system may work best to the extent it is differentiated. The present investigation pioneered an assessment of goal differentiation in relation to an important feature of goals—intrinsic motivation—and quantified the extent to which intrinsic motivation systematically increased from low- to mid- to high-level goals, the resulting individual difference termed cybernetic self-determination. In Study 1 (n = 106), it was found that frustrating daily events precipitated motivations to quit at low, but not high, levels of cybernetic self-determination. In Study 2 (n = 111), it was found that negative feedback was associated with reduced goal persistence at low, but not high, levels of cybernetic self-determination. The findings therefore converge on the idea that individual differences in cybernetic self-determination are consequential in buffering reactions to obstacles in daily life. Implications for personality, motivation, and self-regulation literatures are discussed.     

Effective pursuit of personal goals: The fostering effect of dispositional optimism on goal commitment and goal progress

Personal goals play a leading role in directing behavior and influencing well-being. Thus, it is important to assess goal dimensions promoting effective goal pursuit. The current research aimed at identifying the best predictors of goal pursuit, operationalized as perceived goal progress, among goal-related variables and individual differences in dispositional optimism. Two studies examined the influence of optimism on goal progress, commitment, expectancy, value, and conflict. Moreover, the mediation effect of expectancy in the relationships among optimism, commitment and progress was assessed.Participants in the first cross-sectional study were 283 young people (19–32 years old), whereas participants in the second longitudinal study were 409 people (19–71 years old). They reported their most important personal goals and rated each of them with respect to goal progress, conflict, expectancy, commitment, and value. Dispositional optimism was also assessed.In both studies, multilevel and mediational analyses demonstrated the fostering role of optimism on perceived goal progress and commitment through the mediation of goal expectancy. Thus, optimists are more likely than pessimists to report more perceived progress in their pursued personal goals. By clarifying the role of optimism in fostering goal progress and commitment, this research provides insight on how effective goal pursuit could be promoted.     

Extending the 3 × 2 achievement goal model to the sport domain: The 3 × 2 Achievement Goal Questionnaire for Sport

In the present research, we sought to extend the 3 × 2 achievement goal model recently proffered in the school domain to the sport domain. We did so by conducting two studies focused on the development and initial validation of the 3 × 2 Achievement Goal Questionnaire for Sport (3 × 2 AGQ-S). Study 1 (n = 679), devised items for the questionnaire and demonstrated that data from the questionnaire nicely fit the proposed 3 × 2 model, showed a better fit to the 3 × 2 model than to alternative models, and indicated that each goal variable had good internal consistency. Study 2 again documented the strong psychometric properties of the measure, and additionally linked the goal variables to other constructs central to the achievement goal literature. The establishment of this measure allows extensive study of the 3 × 2 achievement goal model in the sport domain, and promises to yield deeper insights into the nature of achievement motivation in such contexts.     

The Role of Maternal Acceptance in the Relation Between Community Violence Exposure and Child Functioning

Children in the United States are exposed to considerable community violence that has been linked to child functioning. However, not all those exposed, experience negative outcomes. Recent research has focused on factors that “buffer” or protect children from negative consequences of violence exposure. The purpose of this investigation was to examine the potential buffering or moderating role of maternal acceptance in the relationship between community violence exposure and internalizing and externalizing problems. Subjects were 268 urban African American first graders. Community violence exposure was significantly related to symptoms of post-traumatic stress, but did not correlate with either internalizing or externalizing problems for all children, after control for demographics, maternal mental health, and general life stress. However, children's perceptions of maternal acceptance moderated the relationship between violence exposure and internalizing and externalizing problems which included being withdrawn, anxious-depressed, and demonstrating delinquent behavior. Children with the lowest levels of self-reported maternal acceptance were most impacted by community violence. In this sample of urban first graders, low levels of maternal acceptance placed children at greater risk for adverse outcomes associated with community violence exposure compared to moderate and high levels of maternal acceptance.
