Even experienced phone users drive worse while texting – A driving simulator study

Several studies have clearly shown that texting on a mobile phone increases crash risk (e.g. Dingus et al., 2006; Victor et al., 2014). However, the frequency of texting while driving still remains high (e.g. Vollrath, Huemer, Teller & Likhacheva, 2016). One reason may be that drivers are convinced that they are able to manage this dual task due to their competency in driving and texting. From a theoretical point of view, this may be true within limits – two well-learned, automatically processed tasks may require so few resources most of the time that interferences may not occur.In order to test this assumption, a study with a standardized driving simulator task (the lane change task, LCT; Mattes, 2003) was done with n = 40 drivers selected for their driving experience and tested for their texting abilities. The effect of driving experience (high vs. low) and texting competence (high vs. low) on driving performance was examined in single (driving only) and dual-task (driving and texting) conditions. Additionally, a subjective assessment of one’s task performance was obtained. Texting on the mobile phone significantly impaired driving performance. While driving experience did not have an influence, the deteriorating effect of texting was significantly less pronounced in highly competent phone users. Interestingly, this objective effect was not found in the subjective assessment. Drivers with a high texting competence felt as impaired as drivers with a low texting competence. This is in line with the finding that even in this simple driving task their performance was still significantly deteriorated as compared to driving, only. Thus, it seems that the reason why people text while driving is not that they are not aware of the performance loss. However, this awareness of the possible risk does not seem sufficient to prevent them from texting while driving.     

Effects of visual factors during automated driving of mobility scooters on user comfort: An exploratory simulator study

An automated mobility scooter is expected to provide convenient and safe transportation for users in their living area. However, there is limited research on user comfort compared to that on user safety for the automated driving of mobility scooters. Because the user does not perform driving tasks in automated driving, the visual information from the peripheral environment and visual behavior is expected to closely affect the psychological comfort of the user. This study clarifies the effects of factors related to the automated driving of mobility scooters and the peripheral environment on the visual behavior and psychological comfort of the user. Effects of driving velocity and pedestrian density on the visual behavior and psychophysiological responses of users were investigated via a driving simulator. The results showed that automated driving in an environment with a high pedestrian density can result in a decrease in fixation duration, deactivation of visual processing, sympathetic activation, and feeling of negative emotion. This implies that the assessment of visual behaviors of users is important for the design of automated mobility scooters to improve user comfort.     

Differential effects of driver sleepiness and sleep inertia on driving behavior

ObjectivesDriver sleepiness is one of the major safety issues in conventional driving and sleep inertia emerges as a driver state in automated driving. The aim of the present study was to assess the differential impacts of sleepiness and sleep inertia on driving behavior.Method61 participants completed a 10-min manual driving task during an otherwise automated drive. They completed the task (a) under an alert state, (b) under a sleepy state, and (c) after EEG-confirmed sleep. Driving performance was assessed with the parameters lane-keeping, speed choice, and speed-keeping. The eye-blink-based sleepiness measure PERCLOS (the proportion of time with eyes closed) was compared for the three driver states.ResultsLane- and speed-keeping performance were impaired under the sleepy state and after sleep, relative to the alert state. After sleep, lane-keeping behavior recovered rapidly and speed-keeping recovered by trend. Under the sleepy state, performance deteriorated. After sleep, the mean speed was lower than in the sleepy state and in the alert state. PERCLOS was increased after sleep and under the sleepy state, relative to the alert state.ConclusionsAlthough sleep inertia had detrimental effects on driving parameters similar to sleepiness, this effect rapidly vanished. Hence, while brief naps might be suitable to restore alertness in general, the minimal time needed to regain full capacity after napping should be a focus of future research.     

团队中帮助行为的多水平整合模型

团队中帮助行为包含团队成员个体帮助行为, 成员-成员的人际帮助, 以及团队帮助行为。既有研究聚焦于团队中个体帮助行为的积极作用, 忽视了施助者与受助者之间的二元关系影响、以团队为研究层级的帮助行为机理及团队中不同层级间的影响效应研究。研究提出团队中帮助行为的多水平整合理论模型框架, 认为未来研究应进一步探讨团队帮助行为的涌现溢出机制及团队中帮助行为可能存在的负面效应的内在心理机制。     

Mitigating racial microaggressions on campus: Documenting targets’ responses

In this qualitative study, the authors examined responses to racial microaggressions among undergraduate Black, Indigenous, and People of Color (BIPOC) (N = 36) at a large Canadian university. To this end, we employed the consensual qualitative research method (CQR; Hill et al., 2005; Hill, Thompson, & Williams, 1997; Hill, 2012) among seven focus groups. Canadian undergraduate student participants, who self-identified as East Asian (n = 7), South Asian (n = 7), Arab (n = 9), Black (n = 7), and Indigenous (n = 6), expressed four strategic responses to racial microaggressions: using humor to mitigate tension, seeking community and solidarity for support, avoiding or withdrawing for protection and confronting perpetrators and challenging stereotypes. Findings demonstrated the dialectic between avoiding and confronting racial microaggressions, the nuanced role of using humor as a response strategy, and the importance of social support for BIPOC students. Findings are consistent with and extend current proposals of microinterventions. Social identity markers and power dynamics influenced students’ response strategies. Implications and directions for future research are discussed.     

An Exploration of Young Clients' Experiences in Counseling With Post‐Master's Counselors

This phenomenological study adds to current literature about clients' meaningful experiences in counseling by exploring the experiences of eight young clients (ages 8–18) in individual counseling with post‐master's counselors in an outpatient setting. Interviews with these clients revealed the following six themes: (a) the process of growth, (b) having a safe place to talk, (c) counselor accepts and meets the client where they are, (d) counseling is a team effort, (e) supportive accountability from the counselor, and (f) understanding self and others. The final theme includes two subthemes: learning coping and emotion management skills, and learning better ways to communicate and behave. Findings and implications for counselors are discussed.     

Religion and Spirituality among American Indian,South Asian,Black, Hispanic/Latina,and White Women in the Study on Stress,Spirituality, and Health

Social scientists have increasingly recognized the lack of diversity in survey research on American religion, resulting in a dearth of data on religion and spirituality (R/S) in understudied racial and ethnic groups. At the same time, epidemiological studies have increasingly diversified their racial and ethnic representation, but have collected few R/S measures to date. With a particular focus on American Indian and South Asian women (in addition to Blacks, Hispanic/Latinas, and white women), this study introduces a new effort among religion and epidemiology researchers, the Study on Stress, Spirituality, and Health. This multicohort study provides some of the first estimates of R/S beliefs and practices among American Indians and U.S. South Asians, and offers new insight into salient beliefs and practices of diverse racial/ethnic and religious communities.     

母亲积极教养与青少年亲社会行为：共情的中介作用与OXTR基因的调节作用

诸多研究显示母亲积极教养能够促进青少年亲社会行为的发展, 但是迄今对其内在作用机制尚不清楚。本研究基于“基因-环境-内表型-行为”模型, 采用问卷法和DNA分型技术, 对1082名青少年(初测年龄为12.32 ± 0.48岁, 50.3%女生)及其母亲进行为期2年的追踪研究, 考察共情在母亲积极教养与青少年亲社会行为间的中介作用, 以及OXTR基因rs53576多态性对该中介机制的调节作用。结果发现：(1)青少年认知共情(观点采择)在母亲积极教养和亲社会行为之间起中介作用, 而情绪共情(移情关心)的中介作用不显著; (2) OXTR基因对积极教养与亲社会行为间直接路径的调节作用不显著; (3) OXTR基因能够调节“母亲积极教养-认知共情-亲社会行为”中介机制的前半路径, 并且显现出一种超显性的基因效应。在携带GG和AA基因型的青少年中, 母亲积极教养显著正向预测认知共情, 进而增加了其亲社会行为, 而在携带AG杂合子基因型的青少年中, 这一中介效应则不显著。研究结果有助于从催产素受体基因多态性、共情能力和家庭教养等方面阐明青少年亲社会行为的发生机制及个体差异。     

Antecedents of consumer loyalty in ride-hailing

The rise of the sharing economy has remarkedly shifted consumers’ traffic behaviour, which gave rise to successful start-up businesses, such as Uber and Grab, that offer innovative transport alternatives through car and ride sharing. This study investigates consumers’ traffic attitudes and behavioural responses to on-demand ride-hailing. Using structural equation modelling, our survey findings showed that price consciousness, perceived usefulness, ease of use, safety risk and customer value exert significant influences on word-of-mouth (WOM), a manifestation of attitudinal loyalty towards ride-hailing. Contrary to findings in previous studies, our study found insignificant effects of personal innovativeness, subjective norm and perceived privacy security on WOM. In addition, although environmental consciousness is a predictor of WOM, its significant effect on WOM is negative. WOM is found to significantly impact purchase intention which is an indicator of behavioural loyalty. By identifying the antecedents of consumer loyalty in ride-hailing, this study provides recommendations for the ride-hailing ecosystem to generate more sustainable urban transport solutions.
