Can infrastructure improvements mitigate unsafe traffic safety culture: A driving simulator study exploring cross cultural differences

This paper presents the results of a cross-cultural study to investigate the influence of traffic safety culture and infrastructure improvements on driver behaviour. To achieve this, the driving style of UK drivers was compared with that of Nigerians with and without experience of driving in the UK. A driving simulator experiment compared the actual driving style of these three groups of drivers in different safety critical scenarios. The simulated road environment varied depending on how much infrastructure was provided (low or high infrastructure). In addition, the Driver Behaviour Questionnaire was used to collect self-reported data on violations, errors and lapses. It was hypothesised that Nigerian drivers with no experience of driving in a UK road system would report and engage in more unsafe driving behaviour compared to the other two groups, and that increasing infrastructure would have little positive benefit. Overall, the results supported these hypotheses, indicating that the behaviours of drivers are interpretable in relation to their traffic safety culture, compared to changes in their driving environment.     

领导者对员工主动行为的心理与行为反应

员工主动行为因有利于个人和组织的长远发展而受到学界和业界的广泛关注。以往的研究主要关注主动行为对员工本人的人际内影响,而较少考虑对领导者的人际间影响;同时,考虑到员工在领导过程中扮演的重要角色,对员工的主动行为如何影响领导的心理与行为反应做理论性整理将极大丰富对员工主动行为的认识。学界基于归因理论、内隐追随理论、自我-他人评价一致性理论等对上述自下而上的影响过程进行了初步探索,发现领导者对员工主动行为的态度评价和行为反应受到多重边界条件的影响。未来研究可具体化员工主动行为所诱发的领导者心理与行为反应,探索员工主动行为与领导方式的循环关系,以及深挖主动行为与绩效评价之间的内在机理。     

知觉运动学习中的背景干扰效应和元认知监测

选取大学生为被试,采用两因素混合实验设计,以预期按键反应作为知觉运动学习任务.在运动学习任务中,设置了集中练习和分散练习两种练习方式以及三个练习一测试组块.通过分析不同练习方式和练习-测试组块对练习成绩、测试成绩以及元认知监测的影响,考察运动知觉学习的背景干扰效应、练习伴随低估效应以及元认知监测的依据.结果发现: (1)缩短练习与测试之间的时间间隔,经典的背景干扰效应没有出现; (2)在知觉运动学习的多组块练习过程中.元认知监测准确性没有出现练习伴随低估效应; (3)集中练习组更多地以当前的练习成绩作为依据进行预测,从而导致了对预测的高估.     

The New Person-Specific Paradigm in Psychology

ABSTRACT— Most research methodology in the behavioral sciences employs interindividual analyses, which provide information about the state of affairs of the population. However, as shown by classical mathematical-statistical theorems (the ergodic theorems), such analyses do not provide information for, and cannot be applied at, the level of the individual, except on rare occasions when the processes of interest meet certain stringent conditions. When psychological processes violate these conditions, the interindividual analyses that are now standardly applied have to be replaced by analysis of intraindividual variation in order to obtain valid results. Two illustrations involving analysis of intraindividual variation of personality and emotional processes are given.     

Protecting people in research: a comparison between biomedical and traffic research

Traffic research shares a fundamental dilemma with other areas of empirical research in which humans are potentially put at risk. Research is justified because it can improve safety in the long run. Nevertheless, people can be harmed in the research situation. Hence, we need to balance short-term risks against long-term safety improvements, much as in other areas of research with human subjects. In this paper we focus on ethical issues that arise when human beings are directly affected in the performance of research by examining how the ethical requirements in biomedical research can inform traffic research. After introducing the basic ethical requirements on biomedical research, each of the major requirements is discussed in relation to traffic research. We identify the main areas where biomedical research and traffic research differ, and where the ethical requirements from the former cannot easily be transferred to the latter. Finally, we argue that there is a need for systematic studies of the ethics of traffic research and point to some of the issues that need to be addressed.     

A Modest Solution to the Problem of Rule-following

A modest solution to the problem(s) of rule-following is defended against Kripkensteinian scepticism about meaning. Even though parts of it generalise to other concepts, the theory as a whole applies to response-dependent concepts only. It is argued that the finiteness problem is not nearly as pressing for such concepts as it may be for some other kinds of concepts. Furthermore, the modest theory uses a notion of justification as sensitivity to countervailing conditions in order to solve the justification problem. Finally, in order to solve the normativity problem, it relies on substantial specifications of normal conditions such as those that have been proposed by Crispin Wright and Mark Johnston, rather than on Philip Pettit's functionalist specification. This theory is modest in that it does not meet the demands of Kripke's sceptic in full. Arguments are provided as to why this is not needed.     

对人类不良记忆的修饰：来自记忆再巩固的证据

已经巩固的长时记忆被再次提取后, 进入一个记忆的不稳定期, 在此过程中, 记忆可被更新、强化、削弱甚至抹除, 这个过程称为再巩固。人类不良记忆再巩固研究揭示记忆激活后口服普萘洛尔(propranolol)或进行消退训练可削弱或抹除不良情绪记忆, 此过程中涉及杏仁核、海马、前额叶皮层等脑区的参与及其构成的神经环路的调控。当前临床上利用再巩固原理可通过药物治疗、行为干预或无创脑部刺激的方法改变不良记忆。然而, 由于其形成过程复杂并受多种因素影响, 未来研究应尽可能模拟临床中人类不良记忆形成的复杂环境, 深入探讨再巩固“边界问题”, 推动实验室研究向临床应用的转化。     

Are economic conditions related to nonnormative life satisfaction development? Evaluating the relative impact of economic conditions,personality, and subjective health

This study examined the relative contribution of psychological and socioeconomic resources to explaining qualitative individual differences in life satisfaction development. We used growth mixture modeling and a cohort‐sequential design to investigate life satisfaction development from ages 25 to 65, in a nationally representative panel (the Socioeconomic Panel). Eighty‐three percent of the participants experienced stability in life satisfaction. In a subgroup of individuals (10%), life satisfaction declined. This subgroup lived under less favorable economic conditions and reported downward moves on an index of socioeconomic status. In another subgroup (7%), life satisfaction was low at age 25 and increased up to age 65. This group was also socioeconomically disadvantaged but scored higher on adaptive personality traits and experienced upward social mobility. Generally, personality traits explained level differences in life satisfaction better than economic conditions. However, economic conditions explained nonnormative life satisfaction development better than generalized control beliefs and the Big Five traits.     

Living Conditions and Psychological Distress in Latino Migrant Day Laborers: The Role of Cultural and Community Protective Factors

The purpose of this study was to examine the relationship between typically difficult living conditions and psychological distress in Latino migrant day laborers (LMDLs), with attention to the potentially protective roles of contact with family in country of origin (i.e., communication, sending money, etc.), availability of local culture (i.e., food, music, people from one's country of origin), and utilization of community resources perceived to be culturally competent (i.e., services that are respectful, able to serve Latinos, able to solve problems, in Spanish, etc.). Participants were 344 LMDLs surveyed in the San Francisco Bay Area. As hypothesized: (a) difficult living conditions were related to depression, anxiety, and desesperación [desperation], the latter a popular Latino idiom of psychological distress recently validated on LMDLs; (b) contact with family moderated the relation between difficult living conditions and depression and desesperación but not anxiety and (c) access to local culture, and utilization of community resources, mediated the relation between difficult living conditions and depression and desesperación but not anxiety. Implications for intervening at local and larger levels in order to provide some protection against distress built into the LMDL experience in the United States are discussed.
