Due to the absence of a human driver, the introduction of fully automated vehicles (FAVs) may bring new safety challenges to the traffic system, especially when FAVs interact with vulnerable road users such as pedestrians. To ensure safer interactions between pedestrians and FAVs, this questionnaire-based study aims to understand Australian pedestrians’ intention to engage in risky road-crossing behaviors when they interact with FAVs vs. human-driven vehicles (HDVs). A 2 × 2 between-subject design was utilized, in which two risky road-crossing scenarios were designed and took into account the vehicle type (FAV vs. HDV) and vehicle speed (30 km/h vs. 50 km/h). A total of 493 participants (aged 18–77) were randomly assigned to one of the four experimental conditions and completed an online questionnaire based on the extended Theory of Planned Behavior (TPB). This questionnaire measured pedestrians’ intentions to cross the road in the assigned scenarios as well as the motivational factors behind these intentions in terms of attitude, subjective norm, perceived behavioral control, perceived risk and trust in the vehicle. The results show that pedestrians had significantly higher intentions to cross the road in front of approaching FAVs than HDVs. Participants also reported a lower risk perception of crossing in front of FAVs and greater trust in this type of vehicle. Attitude, subjective norm, and perceived behavioral control were significant predictors of intentions to engage in risky road-crossing behavior. Findings of this study provide important implications for the development and implementation of FAVs in the future road transport system. 相似文献

IntroductionPersonality traits can give a fuller understanding for eating behaviors, such as food choice, (un)healhty eating.ObjectiveTo examine eating styles with a multidimensional perspective considering cognitive, affective and conative (or behavioral) components of eating styles in emerging adulthood, and how they may be related to the Big Five and impulsivity traits.MethodsSelf-reported questionnaires were used to explore the association between the eating styles, Big five traits and facets of impulsivity among young French adults (n = 450; Mean Age = 20.84 years; SD = 2.4, with 79.6% of women).ResultsOn the basis of cluster analysis, six eating styles were identified: Healthier, Uninhibited, Dysregulated, Stress-related, Restrictive and Ethical restraint eaters. Results suggest that Uninhibited eaters reported lower scores on Conscientiousness and higher scores on Negative and Positive urgency. The Dysregulated group had lower scores on Extraversion, and high scores on Neuroticism, Negative urgency and Lack of premeditation. Restrictive eaters showed low levels of Openness and Lack of premeditation. The Ethical restraint style was characterized by low scores on Agreeableness and Positive urgency. The ability or inability to cope with both emotional distress and positive and negative impulsive behaviors was related to young adult's eating cognitions and behaviors.ConclusionConsidering the existence of subtypes of eaters and separate associated personality-related traits, an individual differences perspective (e.g., age, gender, disposition to control one's emotional experiences) should be incorporated. 相似文献

ObjectivesThe purpose of this study was to explore the perceptions of expert practitioners and their British sailing team athletes concerning effective, athlete-centered online delivery during a period of COVID-19 restrictions between March and June 2020. In particular, we explored how psychosocial behaviors of practitioners and inherent attributes of online environments influenced the overall wellbeing of the athletes.MethodsUsing appreciative inquiry (AI), which adopts a social constructionist viewpoint, we interviewed nine expert practitioners, which included technical and strength and conditioning coaches, physiologists, and physiotherapists, and 18 elite athletes.ResultsOur results highlight that when delivering sessions online, practitioners expressed psychosocial behaviors that helped build effective relationships, with expression of care and empathy developing closeness, active participation exhibiting commitment, and psychosocial behaviors such as promoting a holistic mindset supporting an athlete-centered approach. Key to these positive outcomes was the connection that practitioners developed with their athletes in these online sessions. Our results suggest that the online environment provide opportunities for practitioners and athletes to reveal part of their personalities and identities that go beyond focusing on performance due to the change in the contextual setting (i.e., restrictions called for a ‘people first’ approach).ConclusionThe findings offer a novel contribution to the literature in highlighting how online environments provide the opportunity to deliver athlete-centered sessions. 相似文献

This study examines homophily among adolescent friends. Participants were drawn from a community-based sample of Swedish youth who ranged from 11 to 18 years old. A total of 436 girls and 338 boys identified their closest friends and described their own delinquent activities, intoxication frequency, achievement motivation, and self-worth. Correlations and difference scores describe similarity between reciprocally nominated friends on each dimension. Adolescents who remained friends from one year to the next tended to be more similar than those who did not, during the friendship and, to a lesser extent, before the friendship. Comparisons with random pairs of same-age peers revealed that age-group homophily accounts for most of the similarity between unstable friends but only a fraction of the similarity between stable friends. 相似文献

The current study attempted to replicate the finding obtained by Powers, Smits, and Telch (2004; Journal of Consulting and Clinical Psychology, 72, 448–545) that both the availability and utilization of safety behaviors interfere with the efficacy of exposure therapy. An additional goal of the study was to evaluate which explanatory theories about the detrimental effects of safety behaviors best account for this phenomenon. Undergraduate students (N = 58) with high claustrophobic fear were assigned to one of three treatment conditions: (a) exposure only, (b) exposure with safety behavior availability, and (c) exposure with safety behavior utilization. Participants in each condition improved substantially, and there were no significant between-group differences in fear reduction. Unexpectedly, exposure with safety behavior utilization led to significantly greater improvement in self-efficacy and claustrophobic cognitions than exposure only. The extent to which participants inferred danger from the presence of safety aids during treatment was associated with significantly less improvement on all outcome measures. The findings call into question the hypothesized deleterious effects of safety behaviors on the outcome of exposure therapy and highlight a possible mechanism through which the mere presence of safety cues during exposure trials might affect treatment outcomes depending on participants’ perceptions of the dangerousness of exposure stimuli. 相似文献

This study examines the precursors of violent behavior among urban, racial/ethnic minority adults. Data are from an on-going study of male and female African Americans and Puerto Ricans, interviewed at four time waves, Time 1-Time 4 (T1-T4), from adolescence to adulthood. Structural Equation Modeling was used to analyze the developmental pathways, beginning in mid-adolescence (T1; age = 14.0 years), to violent behavior in adulthood (T4; age = 29.2 years). The variables assessed were: components of externalizing behaviors (i.e., rebelliousness, delinquency; T1, T3); illicit drug use (T2); peer delinquency (T2); perceived neighborhood crime (T4); and violent behavior (T3, T4). Results showed that the participants' externalizing behaviors (rebelliousness and delinquency) were relatively stable from mid-adolescence (T1; age = 14.0 years) to early adulthood (T3; age = 24.4 years). The participants' externalizing behaviors in mid-adolescence also had a direct pathway to peer delinquency in late adolescence (T2; age = 19.1 years). Peer delinquency, in turn, had a direct pathway to the participants' illicit drug use in late adolescence (T2), and to externalizing behaviors in early adulthood (T3). The participants' illicit drug use (T2; age = 19.1 years) had both direct and indirect paths to violent behavior in adulthood (T4). The participants' externalizing behaviors in early adulthood (T3) were linked with violent behavior at T3, and perceived neighborhood crime (T4), both of which had direct pathways to violent behavior in adulthood (T4). The findings suggest developmental periods during which externalizing behaviors, exposure to delinquent peers, illegal drug use, and neighborhood crime could be targeted by prevention and intervention programs in order to reduce violent behavior. 相似文献

Research finds that religious youth, compared to less religious youth, are more likely to delay their sexual debut (sometimes until marriage). This study is one of the first to examine the influence of involvement in religion‐supported secular activities for shaping initiation into vaginal sex. Does involvement in religion‐sponsored secular programs produce any health‐related benefits for youth? Using two waves of data from the National Study of Youth and Religion this study finds that among teens who have engaged in some of the precursors to first sex, namely, sexual touching, involvement in religion‐sponsored secular activities is associated with lower odds of having first sex between W1 and W2. Conservative attitudes about sex outside of marriage explain, in part, the relationship. Conversely, network overlap, the number of friends who belong to a youth group, and pressure from friends and partners to have sex do not significantly mediate the relationship. 相似文献

Abstract The authors used longitudinal multisource field data to examine core aspects of the adaptive self-regulation model (A. S. Tsui & S. J. Ashford, 1994) in terms of linkages between self-monitoring, discrepancy in manager match-to-position, 5 measures of leadership, and manager performance. At Time 1,64 superiors of focal managers rated the managers' matches to their positions within the organization; at Time 3, they rated the managers' performance. At Time 2, the 64 focal managers completed a measure of self-monitoring, and 192 subordinates rated the focal managers' leadership behaviors. Results of partial least squares analysis revealed that discrepancy in manager match-to-position was associated with reductions in laissez faire and passive management-by-exception behaviors and increases in transformational leadership behavior. Self-monitoring was positively associated with all 5 leadership behaviors. Performance was related positively to transformational leadership behavior and negatively to passive management-by-exception and contingent-reward behaviors 相似文献
