支付与报复：成本形式对第三方惩罚的影响

第三方惩罚不仅对惩罚成本的数量敏感,也对成本形式敏感。在保持成本数量相等的情况下,不同形式的惩罚成本会对第三方惩罚的频率产生不同影响。相较支付形式,当惩罚成本采取报复形式时,被试的第三方惩罚频率显著下降。进一步的实验表明,惩罚频率的变化并非因为不同的成本形式所隐含的风险水平有所差异,而是因为被试对不同的成本形式赋予了不同的主观价值。进一步探索更多形式的惩罚成本是未来研究的重要方向。     

中国青少年积极发展量表（简版）的编制：基于一个大样本数据

中国青少年积极发展量表是一个多维度的测评青少年发展过程中积极特性（即品格、能力、自信和联结）的量表,共98个项目。为提高量表的应用推广性,本研究基于一个大样本数据（n=16317, M_年龄=13.13岁, SD=2.52岁）创建了一个该量表的简化版本。通过一系列的验证性因素分析、项目筛选、信效度检验以及交叉验证,简化后量表共48个项目。结果显示,简版量表与原始完整版量表有足够的概念重合度和剖面相似性,且具有可以接受的信效度和测量结构的等值性。     

作文前计划的时间因素对前计划效应的影响

采用自然实验与实验室实验相结合的方法,通过两个实验探讨作文前计划的时间因素对前计划效应的影响。结果发现,作文方式决定前计划用时,前计划用时影响前计划效应,前计划效应决定前计划形式的作用。这一结果表明,在既有前计划又有外部视觉表征的情况下,前计划本身在前计划时限与前计划形式的关系中起着决定性的作用。因为前计划的存在,使外部视觉表征的作用呈现出更为复杂的情况,从而表现为长时限前计划即充分前计划条件下,外部视觉表征具有重要意义,短时限前计划即不充分前计划条件下,计划比外部视觉表征更具价值。

Bayesian estimation of a multilevel IRT model using gibbs sampling

In this article, a two-level regression model is imposed on the ability parameters in an item response theory (IRT) model. The advantage of using latent rather than observed scores as dependent variables of a multilevel model is that it offers the possibility of separating the influence of item difficulty and ability level and modeling response variation and measurement error. Another advantage is that, contrary to observed scores, latent scores are test-independent, which offers the possibility of using results from different tests in one analysis where the parameters of the IRT model and the multilevel model can be concurrently estimated. The two-parameter normal ogive model is used for the IRT measurement model. It will be shown that the parameters of the two-parameter normal ogive model and the multilevel model can be estimated in a Bayesian framework using Gibbs sampling. Examples using simulated and real data are given.     

视觉词形加工：从脑区到神经通路

视觉词形加工是阅读机制中的重要环节。基于获得性阅读障碍的早期阅读“神经病学模型”对视觉词形加工的神经通路进行了描述。近年来,随着脑功能成像技术的发展和左梭状回中部视觉词形区的发现,研究者们对原有视觉词形加工的神经通路加以补充和修订,并提出了新的模型。该文对视觉词形加工障碍患者的神经心理学研究和正常人视觉词形加工的脑功能成像研究进行了总结,并讨论了研究的局限性,对今后该领域的发展方向进行展望

RELIGION AND SCIENCE IN AN ADVANCED SCIENTIFIC CULTURE

Abstract. These are reflections on the Arkansas creationist trial by a witness for the American Civil Liberties Union. The following points are stressed: First, religion took the lead in defending science at the trial. Second, the appearance of creation science is a function not only of Protestant fudamentalism but also of the establishment of science in our wider culture. It represents a "deviant science" in such a culture. Third, our century has manifested many such bizarre unions of ideological religion and modern science. This shows that science is dependent upon its humanistic, moral, and religious matrix for its social and historical health. Fourth, part of the cause of the rise of creation science has been the power, status, and self–assurance of science that it represents "the only form of truth." Fifth, religion in turn tends both to increase and to become fanatical in advanced and precarious cultures; religion, therefore, needs rational and moral criticism if it would help in the creation of social health.     

Estimation of interhemispheric dynamics from simple unimanual reaction time to extrafoveal stimuli

This essay reviews research on interhemispheric transfer time derived from simple unimanual reaction time to hemitachistoscopically presented visual stimuli. Part 1 reviews major theoretical themes including (a) the significance of the eccentricity effect on interhemispheric transfer time in the context of proposed underlying neurohistological constraints; (b) the significance of gender differences in interhemispheric transfer time and findings in dyslexics and left-handers in the context of a fetal brain testosterone model; and (c) the significance of complexity effects on interhemispheric transfer time in a context of dynamic vs. hard-wired concepts of the underlying interhemispheric communication systems. Part 2 consists of a meta-analysis of 49 published behavioral experiments, in view of drawing a portrait of the best set of experimental conditions apt to produce salient, reliable, and statistically significant measures of interhemispheric transfer time, namely (a) index rather than thumb response, (b) low rather than high target luminance, (c) short rather than prolonged target display, and (d) very eccentric rather than near-foveal stimulus location. Part 3 proposes a theoretical model of interhemispheric transfer time, postulating the measurable existence of fast and slow interhemispheric channels. The proposed mechanism's evolutionary adaptive value, the neurophysiological evidence in its support, and favorable functional evidence from studies of callosotomized patients are then presented followed by proposals for critical experimental tests of the model.
