L3等级自动驾驶条件下驾驶员接管过程及心理模型的构建

自动驾驶是当今智能交通的研究热点,目前正处于由L2等级向L3等级过渡的时期。接管过程作为L3等级自动驾驶车辆人机交互的核心概念,引起了大量研究人员的注意。文章在已有研究的基础上将接管过程划分为警觉唤醒、接管决策和接管执行三个阶段,结合人口学、非驾驶相关任务、驾驶疲劳、信任态度等影响因素加以完善,进一步提出接管过程的三阶段模型。并对接管过程影响因素的未来研究方向,心理机制的构建以及应用现状提出建议。     

社会规范的动态过程

社会心理学的经典研究将社会规范区分为描述性规范与指令性规范。近年来, 研究者从以往对社会规范的静态区分, 开始深入研究社会规范“如何发展变化”的动态过程, 即探究社会规范的习得、传播与转变过程, 以及社会规范发挥作用的影响因素。社会规范的习得可以追溯至童年早期的社会互动, 描述性规范的形成是个体在社会网络中学习社会范畴典型范例的过程, 对现状的合理化催生了描述性规范向指令性规范的转化。社会规范发挥作用也呈现动态性, 不仅与社会规范的心理功能相关, 即遵守或违反社会规范能满足个体的安全感、归属感、独特感需要等, 还与外部环境如权力位置、惩罚机制相关。未来研究可对社会规范形成过程、作用过程做进一步分析; 结合社会规范强度研究, 深入探讨规范性影响的作用过程; 开展文化情境下的社会规范研究等。     

The Effects of Visual Arts Pedagogies on Children's Intrinsic Motivation,Creativity, Artistic Skill,and Realistic Drawing Ability

This exploratory study compared the effects of two different teaching methods (teacher‐directed vs. choice‐based) on the overall art skills, realistic drawing ability, intrinsic motivation to pursue art, and creativity in art productions in children attending the two art programs. The sample consisted of 83 third graders who completed two art exercises and an intrinsic motivation questionnaire. Using the Consensual Assessment Technique, 20 undergraduate art majors rated each drawing on creativity, overall artistic skill, and realistic drawing ability; these scores showed high‐internal consistency and served as measures for art skills and creativity. Children from the teacher‐directed program scored significantly higher on art skill (M = 3.09) than the children from the choice‐based program (M = 2.53, p = .025). Children from the teacher‐directed program also performed better on realistic drawing (M = 3.7, p = .038) than the children from the choice‐based program (M = 2.99). Art teaching method did not predict intrinsic motivation or creativity. Further analyses showed significant correlations between intrinsic motivation scores and overall art skill (r = .376, p = .002) and realistic drawing skill (r = .335, p = .007). Participating in the teacher‐directed program is associated with higher levels of artistic skill and realistic drawing ability, which are correlated with increased intrinsic motivation.     

Conditions for the clean slate effect after success or failure

The act of physically cleaning one’s hands may reduce the impact of past experiences, termed clean-slate effect. Cleaning was found to affect negative, neutral, and mildly positive states. We extend this influence to success, a self-serving state. We manipulated success vs. failure and measured changes in optimism (Experiment 1) or self-esteem (Experiment 2). Moreover, we examined boundary conditions for the clean-slate effect. Experiment 1 indicates that the influence of performance on optimism diminishes if participants knew (compared to did not know) they were cleaning their hands. Experiment 2 indicates that the influence of performance on self-esteem diminishes if participants cleaned themselves (compared to an object). These results suggest that the clean-slate effect requires both awareness and self-reference of the cleaning act. Thus, the clean-slate effect seems to depend on both conscious inferences and automatic processes. A meta-analysis across the experiments confirms a moderate-sized clean-slate effect.     

Difference in the Formation of Attitude Toward Nuclear Power

Determinants of attitudes toward nuclear power in Japan were assessed in a March 1999 survey. The results suggested that persons with interest in and knowledge about nuclear power judged its acceptability on the basis of their perceptions of the sufficiency of electric power and the risks of nuclear power, whereas persons with no interest in and knowledge of nuclear power did not respond on this basis. Although both types of respondents based acceptability on their trust in nuclear power operation and their perception of efficiency, the influence of perception of efficiency on acceptability was stronger for the interested and knowledgeable respondents than for the others. These results partially support the elaboration likelihood model or dual process theory.     

Concrete Tornadoes

I present the case of a Hispanic woman whose physical illness parallels the massive destruction that she witnessed at the World Trade Center. I talk about my own feelings of terror and how I try to deal with my private ghosts as I sit afraid and wanting to help. I mention the longings we all have for powerful parents who can protect us and keep us safe.     

In Search of Bandhood: Consultation with Original Music Groups

Original music groups present a unique and under-explored example of self-initiated task groups. The intragroup life and negotiation of creative differences in three diverse original music groups from New York City were explored. Establishment of a shared group ideology and management of organizational tensions, identified in Murnighan and Conlon's study of professional string quartets, appeared central in the bands' cohesion. The role of group therapist, as a band consultant, was examined.     

Using Technology to Deliver Immediate Corrective Feedback to Preservice Teachers

Teacher preparation programs are under scrutiny for their role in the troubled American educational system. If American education is to improve, teacher educators must identify and encourage teachers to use effective teaching practices. A promising technique for increasing use of teaching practices is providing feedback to teachers on newly acquired behaviors. The focus of this study was to examine the effects of immediate corrective feedback on one specific teaching behavior, use of three-term contingencies, to preservice teachers. A multiple baseline design across participants was used to evaluate the effects of immediate corrective feedback, delivered via a wireless FM listening system. Immediate corrective feedback (as compared with delayed feedback) was shown to be an effective way to increase preservice teacher completion of three-term contingency trials by all participants. These findings and other considerations for additional research using feedback are addressed.     

Cybervision: Virtual peer group counselling supervision — Hindrance or help?

This study explored the use of text‐based computer‐mediated communication in counsellor supervision. ‘Cybervision’ is an innovative collaboration between counsellors and computer technology. The study reports on the use of clinical case presentation by e‐mail and the discussion of cases in text‐based chat rooms. The inquiry, conducted from a qualitative research perspective, seeks to explore the potential effectiveness of Cybervision along with its advantages and disadvantages. Prior to each supervision session, the supervisee presented case concerns by e‐mail and later received 60 minutes supervision from the remaining three group members adopting the role of supervisor. As a form of co‐operative inquiry, the personal experience of research participants was investigated and reported, highlighting key themes and issues relating to the absence of face‐to‐face contact. In all cases, participants reported that Cybervision effectively influenced and informed the clinical practice of the counsellor. Participants quickly and successfully formed a meaningful group where support, challenge and feedback were expressed and valued. The ‘disinhibition’ effect of on‐line contact was found to support open and honest communication. Feelings were communicated in this environment with surprising ease. The consistent emergence of useful parallel processes was another significant finding.
