A cognitive approach to dogmatism: An investigation into the relationship of verbal working memory and dogmatism

This study investigated the relationship of working memory to open and closed belief systems. Two hundred college students completed a working memory span test to measure verbal working memory, and Rokeach’s Dogmatism Scale (1956). Regression analysis was undertaken to determine the contribution of verbal working memory to dogmatism. A negative correlation was found between dogmatism scores and working memory scores (p = .002) confirming the hypothesis that those participants who display a larger working memory capacity would show lower levels of dogmatic beliefs than participants displaying a smaller working memory capacity. Error analysis was employed to determine the significance of inhibition processes; indicating that capacity limits in verbal working memory, and not processing deficits, were primarily responsible for poor working memory scores. Dogmatism was not found to be related to gender, age, ethnicity, religious affiliation, academic major, or level of education.     

后见之明研究综述

后见之明指后见判断(可得益于事件结果反馈的判断)与先见判断(不知晓事件结果时的判断)的系统差异,其研究范式大体可分为两类,假定型设计和记忆型设计。后见效应的研究,具有重大的理论价值和应用价值。文章对后见效应的研究范式、研究结果、及其有关理论进行了简要综述,并对其应用价值加以评述。     

回忆准备就绪程度的判断发展

实验采用 3× 3× 2 (年龄 ,材料 ,性别 )三因素混合实验设计 ,按照学习成绩好、中、差分层随机选取小二、初二、大二被试各 18名 ,其中男女各半 ,选用三种不同的实验材料 ,对被试回忆准备就绪程度的判断发展进行了实验研究 ,得到结论如下 :回忆准备就绪程度的判断准确性随年龄增长而提高 ;回忆准备就绪程度的判断的发展总体上与材料难度无关 ;回忆准备就绪程度的判断发展总体上的性别差异不显著 ;回忆准备就绪程度的判断水平与记忆成绩之间有较高正相关。     

记忆提取研究的新进展

该文从3个方面回顾了记忆提取研究领域内的最新进展:(1)记忆编码和提取之间的关系,主要针对提取过程的自动性和控制性及相应的神经机制进行了讨论;(2)基于记忆提取的抑制机制,主要涉及指向性遗忘、提取-练习范式的研究及负启动范式在记忆提取研究中的应用;(3)工作记忆能力与记忆提取之间的关系,主要集中于工作记忆能力与控制性记忆提取及记忆提取中的抑制机制之间的关系。     

记忆研究的新取向

传统的记忆心理学实验研究,其理念是数量取向的,将记忆隐喻为储藏室;而在近期,记忆研究的理念正朝着准确取向转变,关注记忆是否与实际对应符合。文章对准确取向记忆研究的基本特征予以归纳和分析,并对其涉及的现象、问题和理论进行了介绍。     

分心抑制的年龄差异

通过对负启动范式的说明,从年龄发展的角度对分心抑制作了理论上的探讨,介绍了几个有代表性的理论与假说,包括抑制衰退理论、多样化抑制系统模型和最佳测试时间假说;并从工作记忆能量与分心抑制的关系上探讨了基于年龄发展的资源依赖抑制模型和抑制控制假说。     

不同复述条件下命名难度对图形记忆的影响

采用学习 -再认的方法对自由复述、部分特征的言语命名复述和视觉表象复述三种实验条件下图形的记忆效果进行了研究。结果表明 ,(1)图形记忆中存在明显的难度效应 ,难以命名图形的再认正确率高于易命名图形 ,反应时低于易命名图形。 (2 )被试在复述图形时 ,更倾向于选择那些难以命名的特征作为复述对象 ,以便把整个图形都记住。 (3)易命名图形的言语命名复述成绩好于视觉表象复述 ;而难以命名图形则不存在这种差异。两者自由选择时 ,将加快记忆提取的速度     

网络旗帜广告的记忆效果

由于人们对网络旗帜广告效果的质疑,在网络广告的计费方式上也出现了两种计价模式,分别为按照浏览率和点击率来计量广告效果。其本质问题在于单纯浏览是否能够产生广告效果,以及浏览和点击各自所能带来的广告效果差异有多大。本研究利用模糊测量及相应统计方法,就上网者对网络旗帜广告的记忆效果进行测量。结果显示,在单纯浏览的情况下,上网者对网络旗帜广告已经留有印象,但这种记忆效果并不随着浏览次数的增加而显著改善;点击所能带来的广告记忆效果约为单纯浏览对应效果的1.4~1.5倍     

陈述性记忆存储和巩固的神经机制

综述了陈述性记忆形成和巩固的神经机制,并对经典模型进行了修正和拓展。主要观点是：陈述性记忆的存储和巩固依赖于新皮层不同脑区之间建立新的联系,内侧颞叶在这一过程中起着重要作用;当陈述性记忆完全巩固后,信息的存储和提取完全依赖于新皮质;一个完整的陈述性记忆的信息被分别存储在解剖上分离的语义记忆与情节记忆存储系统内     

A Dissociation between Symbolic Number Knowledge and Analogue Magnitude Information

Semantic understanding of numbers and related concepts can be dissociated from rote knowledge of arithmetic facts. However, distinctions among different kinds of semantic representations related to numbers have not been fully explored. Working with numbers and arithmetic requires representing semantic information that is both analogue (e.g., the approximate magnitude of a number) and symbolic (e.g., what / means). In this article, the authors describe a patient (MC) who exhibits a dissociation between tasks that require symbolic number knowledge (e.g., knowledge of arithmetic symbols including numbers, knowledge of concepts related to numbers such as rounding) and tasks that require an analogue magnitude representation (e.g., comparing size or frequency). MC is impaired on a variety of tasks that require symbolic number knowledge, but her ability to represent and process analogue magnitude information is intact. Her deficit in symbolic number knowledge extends to a variety of concepts related to numbers (e.g., decimal points, Roman numerals, what a quartet is) but not to any other semantic categories that we have tested. These findings suggest that symbolic number knowledge is a functionally independent component of the number processing system, that it is category specific, and that it is anatomically and functionally distinct from magnitude representations.
