韦氏成人智力量表中国修订本与原量表(WAIS和WAIS-R)因素分析的比较研究

本文用主成分分析法对韦氏成人智力量表中国修订本(WAIS-RC)的城市与农村两个常模以及WAIS和WAIS-R进行因素分析,发现这三套测验都负荷较高的g因子;常识,领悟,相似性和词汇测验负荷较高的A(言语理解)因子,填图,木块图,图片排列和物体拼凑测验负荷较高的B(知觉组织)因子,而数字广度,算术和数字符号测验负荷较高的C(记忆/集中注意)因子。因子模型是极相似的,这说明WAIS-RC具有较好的结构效度,保持了原量表的功能。同时,所建立的因子模型也为使用者在使用测验和分析解释结果时提供了有用的参考资料。     

学前和初小儿童智能筛查——图片词汇测试法

美国L.M.Dunn 1965年修改发表的皮勃迪图片词汇测试(PeabodyPicture Vocabulary Test简称PPVT)目前仍是美国智力不足协会(AAMD)所介绍的常用智能测试方法之一。本文参考PPVT制订出适合我国城市学前期与小学初期儿童的图片词汇测试;在上海市区进行标准化;制订了智龄量表、智商和百分位数量表。本测试再测信度r=0.945,二测试者间信度r=0.913。奇偶信度r=0.945,测试标准误σ=4.5。本方法与“学前儿童能力筛查五十项”,“画人试验”,“WPPSI”总智商、语言智商、操作智商,语文成绩,算术成绩的效度相关分别为:r=0.478,r=0.466,r=0.590,r=0.531,r=0.427,r=0.652,r=0.609。本测试制订以来已经数千人次应用,证明是一种简便易行,省时经济,准确性较好,且能进行集体测试的学前及小学初期儿童一般智能(generalintelligence)的筛查方法(Screening test)。     

儿童运动视觉表象操作水平的发展及影响因素

采用计算机软件控制实验,以暴露运动一段行程后进入遮蔽的光点为刺激物,光点以三种不同运动速度、三种不同运动行距组合呈现,要求儿童判断光点到达目标位置时按键反应。结果表明：5—19岁儿童运动视觉表象操作水平的发展存在5一8岁、11—14岁两个加速期;客体运动速度对运动视觉表象操作绩效有显著影响,5、8、11岁组快速较中速下．5．8岁组中速较慢速下操作准确性均有显著降低;客体运动行距对运动视觉表象操作绩效也有显著的影响．5、8、11岁组右目标位置下较中目标位置下操作准确性显著降低;性别对运动视觉表象操作水平无显著影响。     

恐惧发生与预防的实验研究：──Ⅱ、强噪音下不同处理背景动物身心变化的观察分析

采用生理心理学的实验方法．对强噪音下四组不同处理背景大鼠的旷场反应、援食、饮水、排泄和尿生物化学等方面进行比较。结果发现：①Ⅰ组（强刺激组）的各类指标均发生情绪性（恐惧）改变。与２组（预防训练Ⅰ组）、３组（预防训练Ⅱ组）、４组（控制组）以及自身基线（ＭＡＯ）比较差异显著;②适应性训练有助于防止大鼠恐惧发生及上述各类指标发生异常．③由于训练的方法不同,预防的效果也不同。３组与４组比较无显著差异,２组与４组比较某些指标有显著差异。④１组和２组部分大鼠出现皮肤、消化道病变。     

A simple method using a single video camera to determine the three-dimensional position of a fish

In the present paper, we describe a method for recording the coordinates of a fish in an aquarium in a three-dimensional space, using a single video camera and a mirror. We use photogrammetic equations for this, considering the image obtained in the mirror as a virtual image obtained by a second camera. A transformation of the coordinate system is required to express the obtained coordinates in anx,y,z system defined by the edges of the aquarium. The accuracy of the proposed method was estimated, and errors in extreme conditions were found to be 0.8% to 1.2 %, compared with the dimensions of the aquarium used in the test.     

The Role of Psychological Reactance in Drinking Following Alcohol Prevention Messages1

Two experiments tested whether a dogmatic alcohol prevention message may, by arousing psychological reactance (the motivation to reassert a threatened freedom) result in more subsequent alcohol consumption, compared to a neutral message. In Study 1, 535 college students received either a high-threat (dogmatic) or low-threat (neutral) message recommending either abstinence or controlled drinking. Results indicated that high-threat messages were rated more negatively and resulted in more drinking intentions compared to low threat. The negative effect of high threat on message ratings was most pronounced for habitually heavy drinkers and an abstinence-espousing message. In Study 2, under the guise of a “memory study,” 74 college students received either a high- or low-threat message recommending abstinence from alcohol. Then, under the guise of a “perception study,” all subjects participated in a taste-rating task in which their beer consumption was unobtrusively measured. Results indicated that the effect of high threat was most negative for male heavy drinkers, who drank significantly more beer compared to low-threat controls. These results suggest that the persuasive ability of alcohol prevention efforts depend to a considerable extent on the reactance-arousing properties of the materials and that dogmatic alcohol prevention materials may have counterproductive effects for some college students.     

入手术室时的情绪状态和某些心理、生理机能的联系及其和针麻效果的关系

情绪活动和某些生理机能或心理过程的关系很久以来就已进行过大量的研究。外科手术前患者的情绪状态及其相应的生理机能的变化,也曾受到注意。患者在意识清醒状态下进行针麻手术,他的情绪状态对针麻过程及其效果的作用如何,这种情绪状态和某些心理、生理机能有什么联系?这是针麻临床上和理论上应予探讨的问题之一。本工作试图综合分析患者的情绪状态和与之伴随的某些生理生化指标变化,以探讨     

Are effect sizes in self-efficacy field changing over time? A meta–meta analysis

Theories relating to self-efficacy have developed rapidly since Bandura first proposed the concept in 1977. In the past two decades, psychologists have carried out numerous studies to research the cultural and psychological changes in social development. The research topic of this study is whether self-efficacy changes over time. This study uses a meta–meta analysis and includes 13 meta-analyses, including 536 effect sizes, with a total sample size of 421,880. We find that individual self-efficacy increases over time, which may be related to social development trends. However, the effects of interventions on self-efficacy remain similar (Q_model = 1.807, df = 1, p > .05), and a possible explanation is that time effects of self-efficacy confuse the effects of intervention, because both in the intervention group and control group, the average of self-efficacy increases over time. And we find that a general decline in the predictive effects of self-efficacy (Q_model = 5.117, df = 1, p = .024), especially the ability to predict relatively objective variables (e.g. job performance, teaching effectiveness, and transfer of training). A possible explanation is that as social development people tend to overestimate their self-efficacy. Another possible explanation is that the effect sizes in the original studies being overrated, may due to intentional selective reporting or unintentional statistical errors.     

汉语阅读中词切分研究进展

词切分指读者在文本阅读过程中将词从句子或语篇中切分出来以促进文本阅读与加工的过程。本文对近20 年来汉语词切分研究成果总结发现:词间空格、词素特性、词意识、词汇预期均可作为词切分的依据; 汉语阅读存在词n和词n+1两种切分,两种切分过程中字词加工均遵循交互激活假设,切分词n过程中字词加工的交互激活特点表现为字词同等相互影响,切分词n+1过程中字词加工的交互激活特点更多表现为词汇加工影响字加工; 重叠歧义词切分遵循多重激活假设,其中被激活的单词之间的竞争机制符合竞争假设,左侧词汇在这一竞争中具有优势,此外,重叠歧义词的切分受到词频,语境的影响。     

幼儿在联合行动中共同表征能力的发展

为探究幼儿联合行动共同表征能力的发展,实验1通过比较186名3~5岁幼儿在相同任务和不同任务的表现,发现4岁和5岁幼儿在不同任务中的表现比相同任务差;实验2进一步验证幼儿在不同任务中较差的表现源于对自我和同伴的共同表征。结论：3岁幼儿无法在联合任务中同时表征自我和同伴,没有表现出明显的共同表征能力,4岁以上幼儿开始具备稳定的共同表征能力,能够在联合任务中同时表征自己和同伴,由此对自己的行为表现造成干扰。
