A new estimator of the uniqueness in factor analysis

A closed form estimator of the uniqueness (unique variance) in factor analysis is proposed. It has analytically desirable properties—consistency, asymptotic normality and scale invariance. The estimation procedure is given through the application to the two sets of Emmett's data and Holzinger and Swineford's data. The new estimator is shown to lead to values rather close to the maximum likelihood estimator.     

Inequalities among lower bounds to reliability: With applications to test construction and factor analysis

A chain of lower-bound inequalities leading to the greatest lower bound to reliability is established for the internal consistency of a composite of unit-weighted components. The chain includes the maximum split-half coefficient, the lowest coefficient consistent with nonimaginary common factors, and the lowest coefficient consistent with nonimaginary common and unique factors. Optimization theory is utilized to determine the conditions that are requisite for the inequalities. Convergence proofs demonstrate that the coefficients can be attained. Rapid algorithms obtain estimates of the coefficients with sample data. The theory yields methods for splitting items into maximally similar sets and for exploratory factor analysis based on a theoretical solution to the communality problem.     

The more the better – But more of which? Information quantity and shared meaning as predictors of consistency and accuracy in person judgment

This study investigates the consistency and accuracy of person judgments at zero acquaintance in two conditions: Targets were judged repeatedly across a sequence of videotaped situations, either (a) by different observers in each situation, or (b) by the same observer in all situations. Replicating previous research, accuracy increased (inversely accelerated) when including additional situations rated by different observers. However, much of this increase was owed to improved inter-rater reliability (a confound in previous research). Also, cross-situational consistency of judgments was much higher when all ratings came from the same observer. These results underscore the crucial influence of shared meaning on judgment accuracy and consistency.     

Eliciting false memories on implicit and explicit memory tests after incidental learning

Abstract: In a false memory experiment, lists of semantic associates (e.g., newspaper, letter, book, etc.) were presented to three groups of participants to induce false memories for critical nonpresented (CN) words (e.g., read) in an incidental learning task. The control group simply estimated the frequency rate in everyday Japanese discourse of each word on a list. The imagery instruction group received an additional instruction to imagine a thematically related converging word from the target words on a list. Participants in the imagery plus writing group received the same instructions as those in the imagery instruction group, but were also required to write down the word they imagined for each list. The results from the implicit and explicit memory tests given after the incidental learning episode showed that the level of priming for CN words was equivalent to that for actually presented target words for all three groups on the implicit test, whereas explicit memory results showed that participants explicitly recognized more target words than CN words. The implications for implicit associative response and fuzzy‐trace theories of false memory, as well as implicit priming, are discussed.     

不同加工水平对内隐记忆和外显记忆中生存加工的影响

记忆的生存加工优势主要指生存情景下的记忆成绩好于其他情景下记忆成绩的一种优势效应。实验1采用生存加工研究范式,结合内隐记忆和外显记忆测试方法,考察了生存加工在内隐记忆和外显记忆中的表现。实验2结合不同的词语评估时间,进一步考察了不同加工水平对内隐记忆和外显记忆中生存加工的影响。结果发现,在内隐记忆中没有表现出生存加工优势,但是在外显记忆中出现了生存加工优势效应,并且外显记忆中的生存加工优势会受到加工水平的影响。     

工作记忆容量对显、隐性反馈的调节机制研究

本研究选择汉语量词为目标语结构,考察工作记忆容量对显、隐性两类反馈不同的调节机制。105名来自加拿大多伦多地区母语为英语的中学生被随机分为显性修正组、隐性重铸组和控制组,工作记忆容量采用听力跨度测试测量,显、隐性反馈的效果通过语法判断测试与引导性模仿测试分别进行评估。研究结果表明:(1)工作记忆容量有效调节了显性反馈,但对隐性反馈的调节作用不明显;(2)受试的工作记忆容量越高,对显性反馈的调节作用就越明显。     

提供具体信息对学习的影响

本研究采用多重分离程序,对提供具体信息在学习中的作用加以探讨,结果发现：随着指导语外显程度的逐步增高,外显学习效应显著增加,而内隐学习效应无显著变化。     

内隐自尊与外显自尊的关系:多重内隐测量的视角

本研究以102名大学生为被试,从多重内隐测量的视角出发,运用内隐联想测验（IAT）、Go／No-go联想任务（GNAT）和外部情绪性Simon任务（EAST）三种实验程序对内隐自尊及其特性进行了测量和研究,同时运用结构方程建模对内隐自尊和外显自尊的结构关系进行了探讨。结果表明：（1）IAT、GNAT和EASI这三种基于反应时范式的内隐自尊测量方法是有效的,均能有效检测出内隐自尊效应,内隐自尊的特性表现为个体倾向于将自我与积极属性或事物相联,将他人与消极属性或事物相联;（2）内隐自尊与外显自尊是分离的结构,两者是相对独立的两个自我评价系统,支持内隐自尊和外显自尊的两维结构说;（3）双重态度模型和信息加工双过程模型两种理论模型都可以解释内隐自尊和外显自尊的分离现象。     

人格维度、自我和谐及行为抑制与心身症状的关系

研究旨在通过实证研究建立人格维度、自我和谐、行为抑制和心身症状之间关系的结构方程模型。对600余名被试问卷测量的相关、回归和结构方程模型分析表明,人格维度可以直接和/或通过行为抑制和自我和谐对心身症状有着正向或负向的预测作用,而且自我与经验的不和谐、行为抑制和心身症状本身都可以作为心理健康的指标,它们之间又存在密切的相互关系     

The developmental turnpoint of orthographic consistency effects in speech recognition

The influence of orthography on children's online auditory word recognition was studied from the end of Grade 4 to the end of Grade 9 by examining the orthographic consistency effect in auditory lexical decision. Fourth-graders showed evidence of a widespread influence of orthography in their spoken word recognition system; words with rimes that can be spelled in two different ways (inconsistent) produced longer auditory lexical decision times and more errors than did consistent words. A similar consistency effect was also observed on pseudowords. With adult listeners, on exactly the same material, we replicated the usual pattern of an orthographic consistency effect restricted to words in lexical decision. From Grade 6 onward, this adult pattern of orthographic effect on spoken recognition is already observable.
