Lexical Representation and Processing of Morphologically Complex Words: Evidence from the Reading Performance of an Italian Agrammatic Patient

The study of patients with acquired language disorders has provided crucial evidence for contemporary theories on mental lexical representation. This is particularly true for the representation of morphologically complex words. In this paper we analyzed the performance of a patient (M.B.) affected by agrammatism and dyslexia. M.B. was required to read aloud simple and morphologically complex words. The patient's pattern of errors was interpreted as the result of a predominant use of the lexical routine (phonological dyslexia). Three reading tasks were developed which allowed us to test M.B.'s ability to read morphologically complex words (reading of regular and irregular plurals; reading of high- and low-frequency singular and plural nouns; reading of evaluative suffixes). Errors were determined by frequency effect rather than by type of suffix (i.e., inflectional or derivational). High-frequency morphologically complex items seemed to meet stored representations, thus avoiding the parsing procedures that are required for less frequent items. These results are in keeping with dual route models of lexical representation of morphologically complex words.     

作文前构思时间分配及其对写作成绩影响的研究

通过3个分实验考察了优差生的作文前构思时间分配及其不同的构思时间分配策略对作文成绩的影响。实验1发现“优生”和“差生”在无时限写作情况下,前者花在构思上的时间更多,并运用了较好的构思策略;实验2发现“优生”和“差生在限时写作情况下,在构思时间上没有显著的差异,但他们在构思策略上仍表现出差异;实验3发现长时限构思比短时限构思能够带来更好的文本质量。作者对写作前构思的计划和管理,可能是提高作文质量的自我调控策略之一。     

语言书写机制的研究进展：来自失写症的证据

近年来人们采用认知神经心理学方法,通过研究失语症病人的选择性语言功能损伤取得了许多理论成果。该文主要介绍了当前比较认可的书写模型,简要阐述了书写过程中所涉及的认知成分,以及从刺激呈现到拼写出单词的简单动态过程,并回顾了模型建立的实验证据和逻辑思想     

不同条件下拟合指数的表现及临界值的选择

在本模拟研究中设计了6种样本容量,6种因子载荷,和4种评分等级,并考察了正态和非正态分布两种情况。采用的错误模型为参数误置（真模型中每个因子各由5个题目来测量,错误模型中则是第一个因子由6个题测量,另两个因子各由4个和5个题来测量,即有一个因子载荷被误置）模型。结果发现（1）样本量、载荷量、评分等级数和分布形态都对GOF的取值确有影响。其中分布形态的影响最大。NNFI、IFI在不同条件下的平均值是最稳定的,其次是CFI、RMSEA和SRMR。它们都算是值得推荐的GOF,尤其是NNFI和IFI。（2）在正态分布中,当样本量≥1000时,根据NNFI、IFI、CFI、RMSEA、SRMR对模型是否拟合做出判断时有很低的两类错误率,在样本量<1000时则不理想。在偏态条件下无论选择哪个GOF两类错误率都很高。（3）采用2指数策略在很多情况下也不能显著降低两类错误率。（4）由于在数据分布非正态,或正态但样本量<1000时是难判断模型是否拟合的。因此我们提出了2界值策略。即为每个GOF确定上下两个界值。低于下界值时可判断模型是不正确的,而高于上界值时则可判断模型是正确的。GOF取值处于上下界值之间时难以判断模型是否拟合,只能说越高拟合的可能性越大。这时就要通过跨样本验证和增加样本量来确定模型是否正确     

自我表现理论概述

人们把自觉的印象控制过程称作自我表现,它是人与人之间相互作用的一个方面。从Goffman1959年提出自我表现的概念以来,有关问题一直为研究者所关注。因为大部分社会交往活动可以基于自我表现的分析,只有少部分行为可以被认为是没有自我表现的意图。但已有研究主要集中于分析自我表现的类型、自我表现的影响因素、自我表现的策略等问题。而自我表现问题的研究,对于丰富社会心理学的理论,推动相关问题的进一步研究都将具有重要的价值。     

Oral drug self-administration in rhesus monkeys: interactions between drug amount and fixed-ratio size.

During daily 3-hr sessions, 5 rhesus monkeys drank drug solutions and water that were concurrently available. The drug solutions were: 1 milligram per milliliter (mg/mL) pentobarbital (2 monkeys), 1 mg/mL pentobarbital plus 0.5% ethanol (1 monkey), 1 mg/mL pentobarbital plus 1% ethanol (1 monkey), and 8% ethanol (1 monkey). The drug solution and water were available under identical two-component tandem fixed-ratio continuous-reinforcement N schedules. Two variables were manipulated: the size of the fixed-ratio component and the number of liquid deliveries (N) in the second component. Deliveries of the drug solution maintained higher rates of responding than did deliveries of the drug vehicle, water. The number of drug deliveries per session increased with increases in the number of deliveries per fixed ratio and decreased with increases in fixed-ratio size. Analysis of the results in terms of the proportion of deliveries to responses showed that the number of drug deliveries per session was directly related to the size of this quotient. Finally, when fixed-ratio size was repeatedly doubled, the following orderly relationship emerged: The greater the number of available drug deliveries per fixed ratio, the less was the percent decrease in the number of fixed ratios completed per session. It was concluded that increases in the number of liquid deliveries per fixed ratio resulted in increases in reinforcing efficacy.     

知识教学中认知策略与原有知识间关系的实验研究

模拟课堂教学情境,探讨知识教学中学习者的认知策略与原有知识间的相互关系。研究表明,二者存在明显的相互作用,策略学习只有在学习者具备适当原有知识的基础上才能有效地促进学习;当原有知识缺乏时,策略教学对学习成绩没有显著性影响;原有知识水平的高低可直接影响学生的学习成绩。该结论对于实际教学工作具有一定的指导意义。     

成年人现实生活问题解决的年龄差异

采用自行编制的十个与现实生活有关的问题,对２０至８５岁的成年人,分成青年至老老年四个年龄组进行测验,试图探讨成年人现实生活问题解决的年龄差异;并同时进行２０个问题（简称猜图）作业的实验,以期对比研究。结果看到：（１）两组主试对现实生活问题解决的评分一致率合格（ｒ值均在０．７４以上）。（２）对现实生活问题解决提出方案的数量（Ｎ）,三个较年轻组比老老年组答案多些;解决问题有效最高分（Ｈ）和各方案的平均     

Inter-event differences in action memory

Two experiments examined the effect of verb-noun connectivity on recall of simple action phrases, under motor and nonmotor encoding conditions. Connectivity, measured by associative overlap and rated belongingness, was found to make a difference. High-connectivity pairs are better recalled than low-connectivity pairs. Primacy effects are absent with low-connectivity pairs, but generally present with high-connectivity pairs—irrespective of encoding conditions. Inter-item action phrase differences thus influence the effects studied in action memory research. The results were discussed in terms of strategic and nonstrategic conceptions of memory for actions.     

童年压力及死亡威胁启动对择偶要求的影响

本实验从生命史理论出发, 研究童年期环境压力如何与当前环境中的压力线索相互作用并影响个体对异性的择偶要求。被试为70名大学本科生, 其中一部分被试被分配到死亡威胁启动组, 他们阅读一篇描述近期国内暴力犯罪及死亡率上升的新闻报道, 另一部分被试被分配到控制组, 他们阅读一篇描述一个人花了很长时间寻找遗失钱包的文章。被试自我报告对异性的理想择偶要求及其童年压力。控制了性别及恋爱状态后, 多元回归分析表明：童年压力与启动条件仅在身体吸引力的理想标准上有显著交互作用。其中, 低童年压力组在死亡威胁启动下对异性身体吸引力的理想标准显著高于控制条件, 而高童年压力组在死亡威胁启动下对异性身体吸引力的理想要求则显著低于控制条件。此外, 启动条件在异性做“好父母”的择偶标准上有显著主效应, 死亡威胁启动下的被试对异性做好父母的择偶标准高于控制组被试。而在对资源的择偶标准上既不存在童年压力和死亡威胁启动的主效应, 也不存在交互作用。研究说明童年压力与当前环境压力会影响个体对异性的择偶要求, 但对不同择偶要求的影响作用不同。
