目击证人辨认研究

目击证人辨认对司法审判具有重要的意义,这使其成为心理学研究领域的热点之一。本文重点介绍了影响目击证人辨认准确性的因素,即估计者变量和系统变量,并分析了目击证人辨认研究的现存问题。     

比较基因组学研究与应用中的辩证思维

比较基因组学是人类基因组计划的重要组成部分.它利用人类基因组与模式生物基因组之间编码顺序上和组织结构上的同源性,发现和克隆人类基因,揭示基因功能,从而阐明物种的进化关系及基因组的内在结构.比较基因组学的创立、内容及应用都充分体现着辩证思维的哲学观点.     

训诂、解释与文化传承

从中国文化发展的历史看,“训诂”被看做后人继承前人文化的一个重要途径。由于历代统治者出于自身需要而提供大力支持,“训诂学”在中国文化史上成为一门重要的学科之一,尽管近代以后由于新文化运动的兴起而日渐衰落。在西方思想史上,解释学也是一门具有悠久传统的学科,早在中世纪就有了关于圣经典籍的解释学,到了近代有施莱尔马赫和狄尔泰的解释学,到了现代又有伽达默尔的哲学解释学。我们今天把训诂学与解释学放到一起讨论,很大程度上是因为哲学解释学的深刻影响,促使我们对自己文化解释的反思。我们首先必须清楚地认识到,训诂与解释有着…     

"歷数"和"尚贤"与禅让说的兴起

尧舜禅让,古代以为信史。20世纪20年代,有学者提出异议,以为它只是一个传说,这传说是禅让思想的一部分,出自墨家的创造。揆诸史籍,可知,墨家的确传诵过尧举舜而立为天子的故事,对禅让说的传播有推波助澜的作用,但那只是出于宣传尚贤尚同主义的需要,为选官治官而设,并非严格意义上的禅让说。而在儒家,孔子早就盛赞尧舜;尧舜禅让以及与之直接相关的歷数观念在今本《论语》中又有明确反映,这个观念在从周公到孔子的儒家渊源中有着丰富的资源;儒家数观的实质是天命有德,儒家的天命有德思想可为禅让说提供直接的理论基础和前提,儒家的尊贤、墨家的尚贤,后世与“禅让”直接相关的新五德终始说,都可纳入其中。春秋战国时期禅让说的兴起,儒家有直接的关系。     

How linguistic and cultural forces shape conceptions of time: English and Mandarin time in 3D

In this paper we examine how English and Mandarin speakers think about time, and we test how the patterns of thinking in the two groups relate to patterns in linguistic and cultural experience. In Mandarin, vertical spatial metaphors are used more frequently to talk about time than they are in English; English relies primarily on horizontal terms. We present results from two tasks comparing English and Mandarin speakers' temporal reasoning. The tasks measure how people spatialize time in three-dimensional space, including the sagittal (front/back), transverse (left/right), and vertical (up/down) axes. Results of Experiment 1 show that people automatically create spatial representations in the course of temporal reasoning, and these implicit spatializations differ in accordance with patterns in language, even in a non-linguistic task. Both groups showed evidence of a left-to-right representation of time, in accordance with writing direction, but only Mandarin speakers showed a vertical top-to-bottom pattern for time (congruent with vertical spatiotemporal metaphors in Mandarin). Results of Experiment 2 confirm and extend these findings, showing that bilinguals' representations of time depend on both long-term and proximal aspects of language experience. Participants who were more proficient in Mandarin were more likely to arrange time vertically (an effect of previous language experience). Further, bilinguals were more likely to arrange time vertically when they were tested in Mandarin than when they were tested in English (an effect of immediate linguistic context).     

人格测量：从累积式模型到展开式模型

当前大多数人格测量都采用的是累积式反应模型方法,该模型假设被试在测验上的得分随其能力或特质提高而增加,但是随着人格测量技术的不断发展,这一模型的实施效果遭到了质疑,研究者们开始关注展开式模型,该模型认为被试的反应取决于被试能力和项目阈值的匹配程度,当被试能力与项目阈值完全匹配时,被试做出肯定回答的概率达到最高点,称之为“理想点”,展开式模型的目的就是找到被试的理想点,从而寻找其真正的态度强度或人格特质水平。GGUM作为一种比较成熟的展开式模型,已经开始应用于人格测量的各个领域,但仍需要进行大规模的试测,在评估和预测效度方面积累经验,建立业界认可的心理测量学标准,不断探讨和开发相应的心理测量理论和简便易行的统计程序。     

采用词表法变式研究指向遗忘现象

在组内设计的词表法变式任务中,词表一的项目按语义或知觉特征分为遗忘项和记住项,中间指导语要求被试遗忘词表一某类项目的同时记住另一类项目,指向遗忘效应以词表一记住项与遗忘项的差异来反映。实验一中,词表一项目按语义性质分为记住项和遗忘项,结果显示:与控制组比较,标准词表法实验组词表一记忆受损显著,出现传统意义上的指向遗忘效应;变式实验组词表一记忆部分受损,与控制组差异接近.05显著水平;标准词表法实验组以及变式实验组词表二都没有表现出记忆获益;另外,变式实验组词表一记住项与遗忘项之间差异显著,反映出遗忘指导语效应。实验二发现:在变式任务中,指定被试遗忘词表一某种语义性质的项目,结果出现遗忘指导语效应;但是,在指定被试遗忘某种颜色项目时,结果没有出现遗忘指导语效应。变式任务结果比较好地支持提取抑制理论;同时也反映出,词表一记住项与遗忘项之间的区分度是影响变式情境下指向遗忘效应的重要因素。     

Unconsciously learning task-irrelevant perceptual sequences

We demonstrated unconscious learning of task-irrelevant perceptual regularities in a Serial Reaction Time (SRT) task in both visual and auditory domains. Participants were required to respond to different letters (‘F’ or ‘J’, experiment 1) or syllables (‘can’ or ‘you’, experiment 2) which occurred in random order. Unbeknownst to participants, the color (red, green, blue or yellow) of the two letters or the tone (1–4) of the syllables varied according to certain rules. Reaction times indicated that people indeed learnt both the color and tonal regularities indicating that task-irrelevant sequence structure can be learned perceptually. In a subsequent prediction test of knowledge of the color or tonal cues using subjective measures, we showed that people could acquire task irrelevant knowledge unconsciously.     

The nature of the memory buffer in implicit learning: Learning Chinese tonal symmetries

Previous research has established that people can implicitly learn chunks, which (in terms of formal language theory) do not require a memory buffer to process. The present study explores the implicit learning of nonlocal dependencies generated by higher than finite-state grammars, specifically, Chinese tonal retrogrades (i.e. centre embeddings generated from a context-free grammar) and inversions (i.e. cross-serial dependencies generated from a mildly context-sensitive grammar), which do require buffers (for example, last in-first out and first in-first out, respectively). People were asked to listen to and memorize artificial poetry instantiating one of the two grammars; after this training phase, people were informed of the existence of rules and asked to classify new poems, while providing attributions of the basis of their judgments. People acquired unconscious structural knowledge of both tonal retrogrades and inversions. Moreover, inversions were implicitly learnt more easily than retrogrades constraining the nature of the memory buffer in computational models of implicit learning.
