动物创造力和创新研究概述

充满不确定性的环境里,创造力对于人类和动物的生存和进化都起着十分重要的作用。长期以来动物的创造力和创新能力的研究没有受到重视,但最近这个领域开始受到越来越多的关注。该文对动物创造力的有关研究做了简要介绍,并对该领域的发展做了一些探讨     

相继记忆模式：展现情节记忆形成脑机制的窗口

相继记忆模式在记忆形成的脑认知成像研究领域应用广泛,已成为研究者探究大脑形成记忆时活动的主要窗口。该文在介绍相继记忆模式及记忆形成过程的基础上,分析影响相继记忆效应大小和时空分布的因素,最后讨论内侧颞叶及前额叶神经网络中相关脑区如何分工、协同支持情节记忆形成。情节记忆多维度特性导致该神经网络中有关区域表现出不同形式的相继记忆效应,因此,该文提出有效分离这些脑区在记忆形成中如何分工及交互协同关系进行更为重要     

The Observer Video-Pro: New software for the collection, management, and presentation of time-structured data from videotapes and digital media files

The Observer Video-Pro is a system for collecting, managing, analyzing, and presenting observational data. It integrates The Observer software with time code and multimedia hardware components. It extends the functionality of a conventional real-time event recording program in various ways. Observational data can be collected, reviewed, and edited with synchronized display of the corresponding video images. For optimal visual feedback during coding, one can display the video image in a window on the computer screen. Video playback from either a VCR or a digital media file can be controlled by the computer, allowing software-controlled jog, shuttle, and search functions. Besides a wide range of VCRs, The Observer Video-Pro supports all major digital video file formats. The software allows the user to summarize research findings in numerical, graphical, or multimedia format. One can create a time-event plot for a quick glance at the temporal structure of the observed process, or run specific analysis procedures and generate reports with statistics. An Event Summary function is available for exploratory and qualitative analysis. Video material can be summarized in a Video Play List, which allows on-screen summary presentations or the creation of highlight compilations on tape, CD, or other media. Video images can be captured and saved as disk files, for use as illustrations in documents, slides for presentations, and so forth. In this paper we describe the design and operation of the system, illustrated with a case study from research on Repetitive Strain Injury (RSI).     

FOK判断与可接近信息之间的关系

通过三个实验,用语义联想集大小不同的中文单字词研究了靶项目联想集的大小与FOK判断等级和准确性的关系。实验一通过两种不同联想集大小的靶子,比较外显的、提取出的信息和内隐的、语义网络中固有的被激活信息量对FOK判断等级和FOK判断准确性是否有不同的影响。实验二和实验三通过不同的靶子呈现时间和学习遍数,比较不同的识记强度对不同大小联想集的靶子的FOK判断等级和FOK判断准确性的影响。实验结果表明：FOK判断等级随外显的、提取出的信息总量的增多而增高,随内隐的、语义网络中固有的被激活信息量的增多而降低。FOK判断准确性随靶子本身的激活强度的增强而增高,随内隐的、语义网络中固有的被激活信息的激活强度的增强而降低,FOK判断准确性取决于这两种激活强度的综合作用。     

支持性条件对记忆年龄差异的影响

通过三个实验探讨支持性条件对记忆年龄差异的影响。结果表明,在操作条件下记忆高语义关联度项目时,有缩小记忆年龄差异的作用,(实验一);线索回忆时,对于低语义关联度项目,青年人可从名词线索中获得更多支持(实验二);当使用具范畴组织关系的词表作为记忆材料时,操作条件和范畴线索的结合对老年人记忆有干扰作用(实验三)。记忆中年龄差异的变化反映了编码条件、记忆材料和提取条件三方面的综合作用。     

自由回忆中元记忆监控的作用及其影响因素

采用“类信号检测论方法”,通过两个实验,研究了在记忆信息提取过程中元记忆的预见性监测判断（Feeling-of-knowing）和元控制的作用及其影响因素。实验一探讨了识记材料的难易、识记遍数对元监测判断以及输出控制中的反应标准是否有影响;实验二探讨了严格和宽松的奖惩条件对输出控制中反应标准的影响。用计算机随机呈现识记用的词表材料,识记之后让被试进行FOK等级判断和自由回忆,再用“类信号检测论”方法统计实验数据,分析各种条件下回忆成绩、FOK判断等级,计算出相应的符合率和反应标准。实验一结果表明,不同材料难度和识记遍数下的回忆成绩和FOK判断等级差异显著,但输出控制中的反应标准值没受这些因素的影响;实验二结果是严格和宽松奖惩条件下的反应标准值差异显著,严格条件下的反应标准显著高于宽松条件下的反应标准,表明奖惩条件对信息提取中的反应标准有显著影响     

小学一年级数学新教材插图效果的眼动研究

采用2×3两因素混合实验设计,使用美国应用科学实验室（ASL）生产的EVM3200型眼动仪,对小学一年级学生阅读配有不同背景插图应用题的阅读理解指标和眼动指标进行考察。结果表明：无论应用题难易,学生对有背景插图的阅读理解优于对无背景插图的理解;复杂的插图背景有利于学生理解较难应用题;简单的插图背景有利于学生理解较容易应用题;眼动实验结果表明,小学一年级数学新教材插图效果较好     

论民族时代精神对心理学派别形成的影响

心理学是研究人的心理活动规律的科学,而研究心理学的过程无疑问也是一系列心理活动的过程。在研究心理学的心理活动过程中,不同民族的心理学家必然要受本民族的时代精神所影响。从这个角度来分析心理学派别的形成就不难发现:构造派和格式派心理学之所以产生于德国;机能派和行为派心理学之所以产生于美国,决非历史的偶然,它与本民族的时代精神有着密不可分的联系。中华民族的时代精神也必将对建立具有中国特色的心理学产生积极的影响。     

Aging and Ethnicity: Issues for Clinical Practice

Due to dramatic improvements in life expectancy among Americans from diverse ethnic groups, the graying of America is resulting in a particularly marked increase in ethnic diversity in late life. Clinicians must be prepared to address the problems of older ethnic minority patients, who present with distinct problems during late life and may present these problems in culturally prescribed ways. Cultural variations in views about the nature of mental disorders, issues in assessing and treating depression and dementia, and attention to issues of family caregivers are deserving of special attention.     

Fitting multivariage normal finite mixtures subject to structural equation modeling

This paper is about fitting multivariate normal mixture distributions subject to structural equation modeling. The general model comprises common factor and structural regression models. The introduction of covariance and mean structure models reduces the number of parameters to be estimated in fitting the mixture and enables one to investigate a variety of substantive hypotheses concerning the differences between the components in the mixture. Within the general model, individual parameters can be subjected to equality, nonlinear and simple bounds constraints. Confidence intervals are based on the inverse of the Hessian and on the likelihood profile. Several illustrations are given and results of a simulation study concerning the confidence intervals are reported.
