短时作业中警戒绩效影响因素的实验研究:兼用信号检测论分析

本文研究了短时（１小时内）作业中警戒绩效的一些影响因素。实验采用ＥＰ７１０警戒仪,研究了短时作业中时间、信号密度（信噪比）以及信号显著性（占空比）对警戒绩效的影响。使用的方法为信号检测论。因变量指标为辨别力指数ｄ’和判断标准Ｂ。结果发现,作业时间和占空比对警戒绩效没有影响,信噪比对辨别力指数ｄ’有影响但对判断标准Ｂ没有影响。结果提示,在短时作业中,信噪比对警戒绩效起显著作用．     

Eternity in an hour: experiences of time related to psychotherapy sessions

In this paper I consider the individual nature of the way a person develops senses of time. I suggest that something of a patient's early, unvoiced, experience is revealed through the temporal rhythms of interaction with the therapist. I refer to development, cycles of experience, metabolism, transgenerational emotions, experiences of beginnings and endings, early interactions with (m)other, together with narrative and its relation to unconscious processes. Experiences of time within the session indicate the nature of the feelings that are being lived, or refused life. I consider the paradox of living in the present and its relation to chronology. Lastly I give an example of the difficulty of timing comments when there is no flow of feeling, which is, itself, a communication.     

Self-reflection and the temporal focus of the wandering mind

Current accounts suggest that self-referential thought serves a pivotal function in the human ability to simulate the future during mind-wandering. Using experience sampling, this hypothesis was tested in two studies that explored the extent to which self-reflection impacts both retrospection and prospection during mind-wandering. Study 1 demonstrated that a brief period of self-reflection yielded a prospective bias during mind-wandering such that participants’ engaged more frequently in spontaneous future than past thought. In Study 2, individual differences in the strength of self-referential thought — as indexed by the memorial advantage for self rather than other-encoded items — was shown to vary with future thinking during mind-wandering. Together these results confirm that self-reflection is a core component of future thinking during mind-wandering and provide novel evidence that a key function of the autobiographical memory system may be to mentally simulate events in the future.     

孔子是怎样解释《周易》的

孔子与《易》是有密切关系的,抛开《史记》和帛书的记载不言,仅就《论语》中两条最直接的材料来看确实如此。"加我数年……"当为孔子五十之前所说。五十之前,孔子也曾学《易》,而孔子认为知天命之年尤需学《易》。"不占而已"表明孔子解《易》以德,判定吉凶不需要占筮,而是取决于人的德性。孔子以"生生之德性"解《易》,以"道德必然性"解"天命",通过揭去《周易》的神秘外衣,发掘并发展其天人之学,将隐微难言的性与天道托诸于显著的人道德性,发展出天人合一的德性学说。     

未来取向应对的双阶段序列模型及其时间透视机制

最近的研究表明, 未来取向应对对于应激管理起着不可忽视的重要作用。但预先应对和预防应对的关系及其作用机制, 一直是困扰应对研究者的重要问题。我们的前期工作显示, 序列模型比平行模型能更好地表征预先应对和预防应对的内在关系, 时间透视比威胁知觉更能解释预防应对的前因。本项目首次以时间知觉和内隐态度为切入点, 探索未来取向应对机制的理论模型。研究内容拟包括：(1)以大学生就业为情境, 构建未来取向应对的双阶段序列模型; (2)以大学生入学适应为情境, 用内隐认知充实和验证未来取向应对的序列模型; (3)用时间折扣模型的任务范式, 探讨未来取向应对不同阶段的时间透视机制：(4)用威胁性和中性的阈下面孔作情绪启动, 验证未来取向应对不同阶段的时间透视机制。本研究为发掘预先应对和预防应对的关系及其内在机制, 及基于未来取向应对的干预在心理健康和教育领域的应用奠定了基础。     

SINGLE‐SAMPLE DISCRIMINATION OF DIFFERENT SCHEDULES' REINFORCED INTERRESPONSE TIMES

Food‐deprived rats in Experiment 1 responded to one of two tandem schedules that were, with equal probability, associated with a sample lever. The tandem schedules' initial links were different random‐interval schedules. Their values were adjusted to approximate equality in time to completing each tandem schedule's response requirements. The tandem schedules differed in their terminal links: One reinforced short interresponse times; the other reinforced long ones. Tandem‐schedule completion presented two comparison levers, one of which was associated with each tandem schedule. Pressing the lever associated with the sample‐lever tandem schedule produced a food pellet. Pressing the other produced a blackout. The difference between terminal‐link reinforced interresponse times varied across 10‐trial blocks within a session. Conditional‐discrimination accuracy increased with the size of the temporal difference between terminal‐link reinforced interresponse times. In Experiment 2, one tandem schedule was replaced by a random ratio, while the comparison schedule was either a tandem schedule that only reinforced long interresponse times or a random‐interval schedule. Again, conditional‐discrimination accuracy increased with the temporal difference between the two schedules' reinforced interresponse times. Most rats mastered the discrimination between random ratio and random interval, showing that the interresponse times reinforced by these schedules can serve to discriminate between these schedules.     

The role of ecological validity in hazard perception assessment

Hazard perception is one of the few quantifiable components of driving competency that can explain the high crash risk of novice drivers (see Horswill & McKenna, 2004). Some studies focused on investigating the stimulus part of hazard perception items by comparing several design features of the displayed traffic scenarios (e.g. Malone et al., 2012; Scialfa et al., 2013). Other empirical studies have been conducted to address the reaction part of hazard perception items (e.g. Vlakveld, 2014). Among others, existing hazard perception tests differ with respect to the ecological validity – the similarity to real-world demands – of the task that has to be completed by the participants (simple reaction, hazard localization, simulated driving, etc.). Based on the findings of general expertise research (see Glaser & Chi, 1988), the hypothesis of the present experiment was that an increased ecological validity of a hazard perception task has a positive effect on the magnitude of performance differences between more and less experienced drivers. 104 learner drivers and 51 experienced drivers were randomly assigned either to a less ecological valid version (multiple choice task) or a higher ecological valid version (reaction task) of a hazard perception test. In both conditions, the same 20 animated hazardous or non-hazardous traffic scenarios were presented. Overall, the experienced drivers outperformed the learner drivers. Principally, both of the applied versions of the test provided a criterion valid measure of driving expertise. However, increasing the ecological validity of the test by using a reaction task was especially beneficial for certain types of scenarios, leading to higher expertise-related differences. In addition, the reaction task provides response time measure as a further valid performance indicator. This allows the identification of those participants who are indeed able to detect a hazard in a certain scenario, but still have deficits in response time, compared to more experienced drivers. According to the present study, it is recommended to choose the reaction task over the multiple choice task to test hazard perception. Whether a further increase in ecological validity of the task would be useful, should be tested empirically in future research.     

Dogmatism and information gathering in personality impression formation

Subjects were assigned the task of forming an impression of another person with information being gathered from two conflicting sources. One half were given a positive first impression, and one half were given a negative first impression before allowing them to select additional information. Final ratings were made when Ss indicated that they had taken sufficient information. Dogmatic Ss took in less information before passing “final judgment,” gave more extreme stability ratings, expressed greater liking for their agreed-with source, and showed a trend toward a preference for explaining away impression-discrepant information rather than to withhold judgment.     

驾驶经验和危险类型对驾驶员危险检测的影响

结合反应时和信号检测方法,考察不同危险类型下驾驶员危险检测的特点。35名新手和35名有经验驾驶员依次完成一个反应时测试和一个信号检测任务。结果发现：新手对明显和隐藏危险的反应时间比有经验驾驶员长。与隐藏危险相比,驾驶员对明显危险的敏感性高、判断标准低。驾驶员对两类危险的反应时间长是因为他们的判断标准严格。研究结果表明,驾驶员危险检测的特点随着危险类型不同而变化。
