工作记忆对动态范式中基于客体的返回抑制的影响

采用双任务干扰范式探讨了工作记忆对动态范式中基于客体的返回抑制的影响。三个实验分别考察了在言语、空间和视觉工作记忆负载条件下基于客体的返回抑制效应,结果发现只有在空间工作记忆负载条件下,动态范式中的返回抑制才受到损害。这表明空间工作记忆不但在静态范式中的IOR信息的维持和更新中起着重要的作用,在动态范式中的IOR信息的维持和更新中同样起着重要的作用。同时也为动态范式中基于客体的返回抑制的空间抑制动态更新说提供了新的证据     

儿童4岁时自我延迟满足能力对其9岁时学校社会交往能力预期的追踪

采用追踪研究,用实验室实验和情境观察相结合的方法考察了54名儿童4岁时的自我延迟满足能力,5年后结合教师访谈与评定、同伴提名、儿童自评等方法综合评定这些儿童9岁时的学校社会交往能力,探讨儿童4岁时自我延迟满足能力对其9岁时学校社会交往能力的预期作用。结果表明：儿童4岁时的自我延迟满足能力水平可以预期其9岁时的学校社会交往能力水平。4岁时自我延迟满足能力高的儿童在9岁时的学校社会交往能力总体发展也好,其遵守规则与执行任务能力、与教师交往能力、与同伴交往能力、社交情绪发展水平都显著高于那些在4岁时自我延迟满足能力低的儿童;反之则差     

中国人的群体参照记忆效应

在自我参照效应范式中加入参照认同群体加工任务,比较了中国被试在参照中国人和参照美国人进行记忆加工时的再认率及“记得”与“知道”判断的成绩。两项实验结果一致表明,参照中国人加工的再认成绩显著高于参照美国人,表明记忆加工的认同群体参照效应,而在“记得”与“知道”指标上并无差异;参照中国人加工的再认成绩和“记得”判断成绩显著低于自我参照加工。根据个体自我、关系自我和集体自我的分类方法,自我参照效应反映了个体自我对于记忆加工的影响,群体参照效应则主要反映了集体自我的影响     

Dynamic self-organization and early lexical development in children

In this study we present a self-organizing connectionist model of early lexical development. We call this model DevLex-II, based on the earlier DevLex model. DevLex-II can simulate a variety of empirical patterns in children's acquisition of words. These include a clear vocabulary spurt, effects of word frequency and length on age of acquisition, and individual differences as a function of phonological short-term memory and associative capacity. Further results from lesioned models indicate developmental plasticity in the network's recovery from damage, in a non-monotonic fashion. We attribute the network's abilities in accounting for lexical development to interactive dynamics in the learning process. In particular, variations displayed by the model in the rate and size of early vocabulary development are modulated by (a) input characteristics, such as word frequency and word length, (b) consolidation of lexical-semantic representation, meaning-form association, and phonological short-term memory, and (c) delayed processes due to interactions among timing, severity, and recoverability of lesion. Together, DevLex and DevLex-II provide an accurate computational account of early lexical development.     

The facilitative effect of positive stimuli on 3-year-olds’ flexible rule use

This study examined the effect of emotional stimuli on 3- to 4-year old children's flexible rule use, as measured by the Dimensional Change Card Sort (DCCS). In Experiment 1, children in two countries (Canada and China) were given 2 versions of the DCCS. The Standard version required children to sort red and blue boats and rabbits first by shape and then by color (or vice versa); the Emotional Faces version required children to sort happy and sad male and female faces first by emotion and then by gender (or vice versa). Children performed significantly better on the Emotional Faces version, and performance on the 2 versions was related. Order in which dimensions were presented had no effect. Experiment 2 examined which aspects of the emotional faces were responsible for the facilitation of children's performance. Performance on the Standard version was compared to performance on three contextual faces versions, in which children were shown happy, sad, or neutral faces and required to sort them by age (child versus adult) and then by gender (or vice versa). Facilitation was only seen in the context of happy faces. Results are consistent with the suggestion that positive stimuli promote cognitive flexibility, perhaps by increasing dopamine levels in prefrontal cortex.     

Dimensionality of individualism–collectivism and measurement equivalence of Triandis and Gelfand’s scale

Despite researchers’ strong interest in individualism and collectivism (I–C), the conceptualization and measurement of I–C constructs remain controversial. Through a cross-cultural study, the present research examines the dimensionality of I–C and tests equivalence of a measurement scale recently developed by Triandis and Gelfand. Through confirmatory factor analyses, the authors find that conceiving I–C as separate constructs with multiple dimensions is superior and better fits the data. The measurement scale developed based on such a conceptualization is found warrantable although refinements can be made. The results suggest a need for future research on further testing the dimensionality and measurement of the individualism and collectivism scale.     

青少年外向/宜人性人格、互联网服务偏好与"网络成瘾"的关系

该研究采用问卷法,以481名中学生为被试,通过无约束结构方程模型分析方法探讨了外向性、宜人性人格特征与互联网服务偏好的交互作用对网络成瘾的影响。研究发现在对网络成瘾的影响上,青少年宜人性人格特征与互联网社交服务偏好存在显著的交互作用,但与互联网娱乐、信息和交易服务偏好的交互作用不显著。外向性人格特征与互联服务偏好不存在显著的交互作用。(1)从平均影响来看,外向性、宜人性、互联网社交、娱乐和交易使用偏好能够正向预测网络成瘾,互联网信息使用偏好对网络成瘾没有显著的预测效果;(2)在宜人性高分组中,互联网社交服务偏好与PIU的正向关系要强于宜人性低分组。斜率检验表明对于低宜人性人格的青少年来说,互联网社交服务偏好不易导致其成瘾,而对高宜人性人格的青少年而言,互联网社交服务偏好反而容易导致其成瘾。     

"自己的思想":从王弼《周易注》看

忏悔观念与中国文化之悔过精神

文章从中西忏悔观念在中国文化忏悔精神现代讨论中的不同命运入手,通过对"忏悔"概念在语源创生和语际转换中对应状况的梳理,明确了该主题思考的应有思路,并在此基础上,对中国悔过意识的文化底蕴作了初步论证。     

《史记·扁鹊仓公列传》的治疗学思想

《史记·扁鹊仓公列传》是记述扁鹊和仓公医事活动的专篇.目前,中医界大多集中在对其原文的医古文语言学分析、扁鹊和仓公医事活动年代的考证、所载病案的病因病机与诊法的探讨等方面,而专篇探讨扁鹊和仓公治疗学思想的研究尚缺,本文就此加以论述,并与《内经》简单地对照.
