幼儿从电视中学单词──项伴随学习的研究

对幼儿从电视中伴随学习单词的可能性及其影响因素进行了初步的探讨。４０名小班幼儿和４６名大班幼儿参加了实验,他们在接近自然的状态下观看有字幕的动画片。结果发现：幼儿在无任何指导的情况下观看有字幕的动画片,能伴随学习到汉字,这表明,电视对幼儿的词汇发展有着积极的影响;不同性别的儿童都能同等程度地从电视中伴随学习到单词;词义的伴随学习受幼儿原有的词汇水平和幼儿对目标词熟悉程度的影响;词音的伴随学习只发生在词汇水平较高的幼儿当中,并且随着幼儿对目标词熟悉程度的增加而增加;词音和词义的伴随学习存在频度效应。     

Antecedents of information-processing skills in infants: Habituation, novelty responsiveness, and cross-modal transfer

Three skills which characterize cognitive functioning in human infants in the middle of the first year of life—habituation, novelty responsiveness, and cross-modal transfer—predict mental ability in later childhood. Antecedents of each skill at 5 months postnatal were examined in a short-term prospective longitudinal study of infant ability and maternal intelligence and interaction style. Infant perceptuocognitive performance at 2 months, maternal intelligence, and maternal responsiveness at 5 months relate to the expression of the three infant cognitive skills, but in different ways. Variation in infant information-processing abilities can be explained by specific child and maternal factors that are evident soon after birth.     

句子先提述的参与者在可提取性上的优势现象

下述五个实验就汉语句子成分（包括句子的参与者及其动作）的提述次序对其可提取性的影响进行了研究,结果表明：（１）句子先提述的参与者比后提述的参与者容易被提取,提述的次序对参与者的可提取性有明显影响。（２）先提述参与者的这种优势与句子呈现的方式有一定的关系。（３）在系列呈现的条件下,先提述参与者的易提取性与探测词呈现的延迟间隔有关。（４）在系列呈现的条件下,参与者以名词形式出现时,被试的反应速度较快,而参与者以名字的形式出现时,反应则较慢;在同时呈现的条件下这种差异基本消失。（５）句子参与者的行动（即句子的动词）的提述次序对其可提取性也有明显的影响,说明提述次序对句子成分的可提取性的影响,不只限于句子参与者本身。     

The Older Native American Indian With Disabilities: Implications for Providers of Health Care and Human Services

This article presents a review of the literature as regards the older Native American Indian, as well as a report of health care and human service needs based on a recent study of urban Native American Indians with disabilities in the Denver metropolitan area.     

教师工作满意度的测量研究

本研究运用一个＂教师工作满意度量表＂,对北京、天津、大连及青岛等四省市的２０４名小学教师进行了测量,结果表明：（１）教师们在工作性质、职业投入感及人际关系这些内在因素上的满意度较高,而在薪水、领导管理、进修提升及物理条件这些外在因素上的满意度较低;（２）女教师的工作满意水平显著高于男教师;（３）从事＂教师＂这一职业的动机对教师的工作满意度有显著的影响。     

Moderation and Mediation of HIV-Prevention Interventions: Relationship Status,Intentions, and Condom Use Among College Students1

This study examined the effects of 2 HIV prevention interventions on condom use and mediators of condom use. College students were randomly assigned to a control condition or an intervention (communication skills or technical skills). Those who received either intervention had greater condom use self-efficacy, more positive condom use attitudes, and stronger intentions to use condoms than did controls. Furthermore, 3-month follow-up data revealed that students in either intervention who were not in a steady dating relationship reported more consistent condom use than did those in the control condition, whereas students who were in either intervention and in a relationship reported somewhat less consistent condom use than did those in the control condition. Analyses suggested that effects of the interventions on condom use were mediated by increased intentions to use condoms.     

语义联系类型和强度对预期推理生成的制约作用

首先采用开放式问卷实验方法,由被试生成日常生活中的事件以及组成这些事件的各种活动和活动的参加者。然后,对这些事件熟悉性、对活动的典型性和可区分性三个维度进行主观评价,形成事件以及每个事件活动序列,并据此编制实验材料。实验主要考察活动的典型性和可区分性对于熟悉性高的事件的预期推理的影响,以及不同工作记忆能力的被试进行事件预期推理时的加工模式。实验结果表明：（１）高工艺记忆能力的被试对事件的预期量小于     

LTP诱导期向维持或转化过程中的突触形态学特征

该研究探讨了视皮层ＬＴＰ由诱导期向维持期转化过程的突触形态学特征。实验选用１８－３０天龄的健康ＳＤ大鼠,分实验组、空白对照组及实验对照组进行电镜观测和图象分析。结果发现,在常规ＬＴＰ实验程序中强直刺激后有ＬＴＰ产生并记录８０分钟的实验组脑片标片,局部有界面曲率大于２的较大Ｕ型突触形成,这种突触多有两个以上活性区。图象分析结果显示,实验组与对照组相比较,突触的界面曲率明显增大（Ｐ〈０．０５）,活性区
