复杂图形的双眼视差敏感性

该研究用心理物理学实验方法,以能正确分辨图形在深度上起伏周期数的多少作为判据,检测了七名被试的体视性能。实验结果表明,被试者观看复杂图形的视差敏感性是和图形在深度上变化的复杂程度有关。如果以视差作纵坐标,以图形在深度起伏频率为横坐标,则其深度感知的范围是一个区域,该区域的频率变化范围是从０．１周／度到４周／度,当深度变化频率大于４周／度,则无深度感知。七名被试的双眼深度敏感区有个体差异,但其区域的形状是相似的。     

Attribute‐based differentiation of alternatives

An intermediate step is introduced to the dialogue decision process for decision analysis. Alternatives are refined after they have been generated within a strategy table but before they are subject to more detailed evaluation. Two or more judges create a subjective mapping from alternatives to attributes that will later be mapped to criteria. In strategy tables, each of the alternative strategies consists of a coherent set of choices made across several decisions that are to be coordinated. These strategic alternatives are modified so as to increase their differentiation in the attribute space, rather than in the decision space alone. When criteria weights are unknown, the best alternative from the modified set may be superior to the best alternative from the original set. Furthermore, analysis of the resulting alternatives may yield a better mapping of the value response surface for the action space, in the sense that this mapping leads to eventual construction of a higher value alternative. Results are reported for a consulting engagement incorporating the proposed step. Copyright © 2003 John Wiley & Sons, Ltd.     

记忆的顿悟优势效应

记忆的顿悟优势效应指, 与加工非顿悟问题相比, 加工顿悟问题能够产生更优的记忆保持量。该效应在顿悟的两种操作性定义以及不同实验材料中稳定出现。基于顿悟阶段观, 研究者提出两种理论解释记忆的顿悟优势效应的认知机制：认知的生成效应和表征转化理论认为, 顿悟加工过程中的认知努力、适当迁移加工以及顿悟的表征转换加工促进记忆的保持效果; 情绪的“啊哈”体验理论认为, 加工顿悟问题后的情绪对后续的信息提取具有促进作用。未来的研究可从优化顿悟的指标、巩固记忆的顿悟优势效应、评估其持续性以及更加系统探讨记忆的顿悟优势效应的认知机制等四个方面展开。     

The Enjoyment of the Sage and the Common People: A New Perspective on the Cosmology of the Laozi

The Laozi laughs at the joy of those who violate the Dao and praises the suffering of those who attain it,yet this does not mean that the political philosophy of the Laozi does not encompass a notion of happiness,a notion that is grounded in the "enjoyment of something together" (gong le共樂) by the sag and the common people.The philosophical foundation of the Laozi's view of happiness is its cosmology,of which there are two sequences:one is generation and the other is growth.With the influences of Wei/Jin-era metaphysics and Western philosophy,Chinese scholars used to overemphasize generation,tracing only the origin.But in the cosmology of the Laozi,both generation and growth are indispensable,and this is part of the reason why the Dao and the De are equally important in the Laozi.The happiness of the common people does not come from a psychological dependence on or attachment to certain form of domination,but from the full development of each individual's initiative and action affected by Mysterious De.     

A belief in trend reversal requires access to cognitive resources

There are two research traditions studying people's reactions to random binary events: one concerns serial choice reaction times, the other concerns predictions of events in a series. The present studies focused on comparing expectations between these two approaches. We formed and tested a general hypothesis that, regardless of the type of task, when an individual faces a sequence of events they initially expect trend continuation. Only when people assume that a sequence is random might they override the default and expect trend reversal instead. In a series of experiments we found that limitation of access to cognitive resources enhances expectations of trend continuation. Our interpretation of this finding is that an expectation of trend continuation is the default for the human cognitive system and that a belief in trend reversal requires access to cognitive resources to overcome the tendency to expect trend continuation.     

Divided attention enhances explicit but not implicit conceptual memory: an item-specific account of the attentional boost effect

The Attentional Boost Effect (ABE) refers to the counterintuitive finding that words encoded with to-be-responded targets in a divided-attention condition are remembered better than words encoded with distractors. Previous studies suggested that the ABE-related enhancement of verbal memory depends upon the activation of abstract lexical representations. In the present study, we extend this hypothesis by embedding it in the context of a broader perspective, which proposes that divided attention in the ABE paradigm affects item-specific, but not relational, processing. To this purpose, we examined the ABE in the matched tasks of category-cued recall (CCRT: explicit memory) and category exemplar generation (CEGT: implicit memory). In addition, study time was varied (500, 1500 or 4000?ms), to further determine whether the attentional boost manipulation could influence late-phase elaborative processing. In agreement with the predictions of the item-specific account, the results showed that exemplars encoded with targets were recalled better than exemplars encoded with distractors in the CCRT, but not in the CEGT. Moreover, performance in the CCRT increased with study time, whereas the size of the ABE-related enhancement tended to decrease, further confirming that this effect hinges upon early phase encoding processes.     

Body Dissatisfaction in College Women and Their Mothers: Cohort Effects, Developmental Effects, and the Influences of Body Size, Sexism, and the Thin Body Ideal

A study of body dissatisfaction, as measured by the Figure Rating Scale (Stunkard, Sorenson, & Schlusinger, 1983) and the Body Esteem Scale (Franzoi & Shields, 1984), in 75 college women and their mothers indicated that both daughters and mothers experienced body dissatisfaction. When body size was statistically controlled, either no difference was found between the groups or daughters were found to have greater body dissatisfaction than mothers. The results supported the hypotheses that (1) there are generational differences in body dissatisfaction, (2) both cohort and developmental effects contribute to these differences, and (3) that a developmental effect (mothers' greater body size) may obscure a cohort effect (daughters' greater exposure to the thin body ideal). Body dissatisfaction measures based on the mothers' retrospective ratings of how they felt at their daughters' age were consistent with these hypotheses. Relationships between body dissatisfaction and the Sociocultural Attitudes Toward Appearance Questionnaire (Heinberg, Thompson, & Stormer, 1995) were stronger and more frequent for daughters than for mothers and for the Internalization Scale than for the Awareness Scale. Relationships between the Ambivalent Sexism Inventory (Glick & Fiske, 2001) and body dissatisfaction were stronger for mothers than for daughters and for Benevolent Sexism than for Hostile Sexism.     

论公共管理中不道德手段的生成与控制

公共生活要得到有效而又合理的管理必须运用道德的手段。有的公共管理机构及其人员出于提高管理效率或者实现私人目的的考虑,可能会选择不道德的手段。由于不道德的手段会造成严重的道德后果,因此,就有必要对其予以合理控制。这种控制既需要合理的道德观念的支持,又需要刚性的内部控制与外部控制的配合。
