决策任务类型与结果框架对风险决策的影响

本研究考察生命和金钱问题下,获得和损失框架中决策任务类型对风险决策的影响。采用2（任务领域：生命、金钱）×2（决策任务类型：经验、描述）×2（结果框架：获得、损失）被试间设计,使用卡方检验及logistic回归分析后发现：生命和金钱问题下,个体在直接给出方案可能结果的描述性决策中仅表现出损失框架下的风险偏好;在通过自主查看方案可能结果的经验性决策中未发现结果框架作用。描述−经验差距一致性存在于生命和金钱问题中。     

The Memory of Micro-Organisms: An Essay on the Experience of Environmental Alterations by Bacteria

Using a generalized conception of experience, from which all features characteristic for higher animals (such as consciousness and thought) have been removed, allowed relating experience to adaptive processes in lower organisms. The temporal vector character of every current experience, containing as well memories of past experiences as intentions for future activities, can then be found in the adaptive response of cyanobacteria to alterations in phosphate supply, particularly in energetic manifestations of this phenomenon. A possible analogy between adaptive events as the “atomic units” of physiological adaptation and Whitehead's actual occasion of experience is discussed.     

Musical experts recruit action-related neural structures in harmonic anomaly detection: Evidence for embodied cognition in expertise

Humans are extremely good at detecting anomalies in sensory input. For example, while listening to a piece of Western-style music, an anomalous key change or an out-of-key pitch is readily apparent, even to the non-musician. In this paper we investigate differences between musical experts and non-experts during musical anomaly detection. Specifically, we analyzed the electroencephalograms (EEG) of five expert cello players and five non-musicians while they listened to excerpts of J.S. Bach’s Prelude from Cello Suite No. 1. All subjects were familiar with the piece, though experts also had extensive experience playing the piece. Subjects were told that anomalous musical events (AMEs) could occur at random within the excerpts of the piece and were told to report the number of AMEs after each excerpt. Furthermore, subjects were instructed to remain still while listening to the excerpts and their lack of movement was verified via visual and EEG monitoring. Experts had significantly better behavioral performance (i.e. correctly reporting AME counts) than non-experts, though both groups had mean accuracies greater than 80%. These group differences were also reflected in the EEG correlates of key-change detection post-stimulus, with experts showing more significant, greater magnitude, longer periods of, and earlier peaks in condition-discriminating EEG activity than novices. Using the timing of the maximum discriminating neural correlates, we performed source reconstruction and compared significant differences between cellists and non-musicians. We found significant differences that included a slightly right lateralized motor and frontal source distribution. The right lateralized motor activation is consistent with the cortical representation of the left hand – i.e. the hand a cellist would use, while playing, to generate the anomalous key-changes. In general, these results suggest that sensory anomalies detected by experts may in fact be partially a result of an embodied cognition, with a model of the action for generating the anomaly playing a role in its detection.

Implicit Mental Processes in Ethical Management Behavior

This article examines the relationship between implicit mental processes and ethical decisions made by managers. Based on the dual-process view in social and cognitive psychology, it is argued that social cognition (e.g., moral judgments) can rely on two different modes of information processing. On one hand, moral judgments reflect explicit, conscious, and extensive cognitive processes, which are attributed to explicit attitude. On the other hand, moral judgments may also be based on implicit, automatic, and effortless processes referring to implicit attitude. To test this thesis, a study involving 182 participants was conducted. The results support the thesis.     

How Psychotherapists Address Hypothetical Multiple Relationships Dilemmas with Asian American Clients: A National Survey

This study examined how psychotherapists address hypothetical nonsexual multiple relationships dilemmas with Asian American clients and identified predictors of conservative decisions and the use of culture-based rationales. This survey of 787 Asian American and non-Asian American psychotherapists revealed that clinicians rely on mostly their personal policies and seldom focus on the clients' cultural backgrounds. Psychotherapists who consider their clients' Asian culture have more cultural knowledge and awareness, have been mental health providers longer, and are Asian American and female. Clinicians who avoid multiple relationships tend to cite formal policies as justification and are less likely to consider clients' cultural worldviews, the therapeutic relationship, or their own values. The results are discussed in terms of specific revisions needed in the American Psychological Association Ethics Code, the benefits of more frequent consultation with colleagues and supervisors about ethical dilemmas, and recommendations for psychotherapists.     

Strategies School Practitioners Report They Would Use to Resist Pressures to Practice Unethically

Abstract

This study focused on strategies school psychologists and special education teachers report they would use to resist administrative pressures to practice unethically. Data came from a national sample of 141 school psychologists and 130 special education teachers who responded to a survey by predicting how they and others would respond to four ethical dilemmas. Qualitative analysis of data revealed four strategies that were generalized across all dilemmas. These general strategies were: preventing dilemmas from occurring; educating and/or threatening others; involving others in solutions; and combining strategies into more comprehensive responses. Qualitative analysis also revealed three strategies that were suggested for only some of the dilemmas (dilemma-specific strategies). Both the general and dilemma-specific strategies appear potentially useful to practitioners seeking ways of resisting pressures to practice unethically.     

直觉在军事决策中的应用

直觉决策是以决策者经验为基础的无意识的决策过程.现代战争的动态性、不确定性、复杂性和模糊性要求指挥员在战场当中要善于利用直觉进行快速决断.受到决策的双系统理论以及再认启动决策模型思想的影响,美军从20世纪80年代后期开始重视直觉决策在制定作战计划中的作用,相关研究机构积极探索培养指挥员直觉决策能力的方法,作战条令中也逐渐融入了直觉决策的理念.美军的研究发现和实践结果不仅揭示了基于经验的直觉决策过程的内在心理机制,而且对我军培养适合于未来战争的优秀指挥人才具有启示作用.
