特殊儿童个案研究资料收集的方法

本文介绍了特殊儿童个案研究中资料收集的三种重要方法：观察法、访谈法和档案资料法。本文较详细地介绍了各种方法的定义、性质,包含的不同类型,不同角色的研究者与被试之间的关系,以及怎样合理利用不同方法获得的资料等。这三种方法各有自己的优点和缺点,为保证研究资料的多样性和有效性,在个案研究中常常是联合运用的。     

工作记忆与领域知识在个体认知行为中的作用

新近研究表明,工作记忆和领域知识在个体认知行为上起了积极的作用,对二者关系的研究有三种观点：一是强调工作记忆或领域知识在认知行为中的单独作用;二是综合考察二者在个体认知行为中的不同作用;三是建立模型,阐述工作记忆和领域知识在认知行为中的作用。最后针对当前有关此方面的研究,探讨有关工作记忆和领域知识作用研究的发展趋势。     

Quasi-truth,paraconsistency, and the foundations of science

In order to develop an account of scientific rationality, two problems need to be addressed: (i) how to make sense of episodes of theory change in science where the lack of a cumulative development is found, and (ii) how to accommodate cases of scientific change where lack of consistency is involved. In this paper, we sketch a model of scientific rationality that accommodates both problems. We first provide a framework within which it is possible to make sense of scientific revolutions, but which still preserves some (partial) relations between old and new theories. The existence of these relations help to explain why the break between different theories is never too radical as to make it impossible for one to interpret the process in perfectly rational terms. We then defend the view that if scientific theories are taken to be quasi-true, and if the underlying logic is paraconsistent, it’s perfectly rational for scientists and mathematicians to entertain inconsistent theories without triviality. As a result, as opposed to what is demanded by traditional approaches to rationality, it’s not irrational to entertain inconsistent theories. Finally, we conclude the paper by arguing that the view advanced here provides a new way of thinking about the foundations of science. In particular, it extends in important respects both coherentist and foundationalist approaches to knowledge, without the troubles that plague traditional views of scientific rationality.     

Parallel processing of stimulus features during RSVP: evidence from the second response

When observers are asked to report a feature of a single target displayed in rapid serial visual presentation, they frequently make errors. Most frequently, a feature from the to-be-reported dimension pertaining to a stimulus presented near the target is reported. These migrations are so-called illusory conjunctions in the time domain. From parallel models, it is proposed that during the presentation of the series, the response features of the stimuli are extracted. If a high rate of presentation does not enable proper binding processes, the system could base its response on sophisticated guessing on the basis of the relative levels of activation of the available response features. However, the multiple extractions assumption has not received direct empirical support. We report two experiments in which the observers had to report their first and second response candidates. This double response paradigm makes it possible to test the assumption that more than one response feature is available for making a response. Furthermore, the application of the constant ratio rule (following Botella, Barriopedro, & Suero's, 2001, model) to the first responses allows predictions for the ratios between choices of the items for the second responses. The correlations between the observed and the predicted response proportions were .887 and .956 in the two experiments. This high predictive capacity indicates, first, that the observers have more than one response available, among which to choose, and second, that the choice among responses is determined largely in the same way for both, first and second responses. Nevertheless, the small errors in prediction are further reduced if a proportion of pure guesses is assumed in the second responses. These are probably due to memory losses, misidentifications of the features, and other factors impairing performance in second responses in comparison with first responses.     

Between-group differences and taxometrics

In psychological research it can be of interest to differentiate between the categorical (taxonic) vs dimensional (nontaxonic) nature of phenomena, for example in the field of psychopathology. For categorical (taxonic) structures a further differentiation is possible: between categorical structures with dimensional equivalence and a substantial main effect, and structures without dimensional equivalence (independent of the main effect). Previous taxometric studies have not concentrated in an explicit way on the case of nonequivalence. It is shown here that under favorable circumstances both types of categorical structures can be detected using the taxometric procedure L-Mode, but that they cannot be differentiated from one another.     

Language Switching and Mexican Americans' Emotional Expression

This study examined the effects of counselor language switching and counselor ethnicity on bilingual Mexican American participants' emotional self‐disclosure. Counselor language (English only and Spanish with English) was crossed with counselor ethnicity (Mexican American and European American) to produce 4 treatment conditions. Judges' observations revealed that the European American counselor who language switched elicited the most emotional expression from participants. Este estudio examinó los efectos que un cambio de idioma por parte del consejero y la etnicidad del consejero tienen sobre la auto‐revelación emocional de los participantes México Americanos bilingües. El idioma del consejero (sólo inglés, y español con inglés) se combinó con su etnicidad (México Americano y Euro Americano) para generar 4 condiciones de tratamiento. Las observaciones de los jueces revelaron que el consejero Euro Americano que cambió de idioma obtuvo el mayor número de expresiones emocionales de los participantes.     

The WebQuest: An Illustration of Instructional Technology Implementation in MFT Training

This teaching case illustrates the innovative application of an instructional technology modality, the WebQuest, in family therapy training. It describes what a WebQuest involves, and how it can be used as a tool for developing critical thinking and application of contemporary marriage and family therapy (MFT) theory to social and global issues. The authors discuss the results of the survey and focus groups conducted to assess the value of this assignment from the students’ perspectives. Results indicate that its application in a family therapy theories course fostered students’ awareness of global issues impacting family life, integration of family therapy theories to serve children and families, creativity in developing their own intervention models, and ability to discuss and integrate knowledge from different knowledge bases and perspectives.     

成年个体的心理理论与执行功能

为了说明成年个体心理理论与执行功能的发展及两者的关系,在匹配了智商和教育水平条件下,采用心理理论故事理解任务、失言理解任务和威斯康星卡片分类任务分别探察了30名62~77岁的老年人和30名19~25岁青年人的心理理论和执行功能。结果表明,老年人和青年人在2种心理理论任务上的得分与卡片分类任务的得分都不存在显著相关,老年人在失言任务上的得分显著低于青年人,在心理理论故事理解任务上和威斯康星卡片分类任务上,老年人的表现与青年人没有显著差异。结合已有的研究结果提示：心理理论与执行功能的相关模式在成年和学前阶段是不同的。     

重复线索化和靶子注意定向对返回抑制的影响

在返回抑制范式下 ,利用线索—靶子模式进行了两个实验 ,以大学生为被试 ,以重复线索化次数来操纵线索化阶段的注意 ,以靶子的注意定向来操纵靶子加工阶段的注意 ,探讨注意对返回抑制的影响。实验一采用连续线索化方式 ,发现当靶子为自主性注意定向时 ,线索化次数对返回抑制有显著影响 ,线索化 3次时返回抑制值大于线索化 1次和 2次 ;当靶子为反射性注意定向时 ,线索化次数对返回抑制无影响。实验二采用交叉线索化方式 ,发现线索化次数对返回抑制的影响正好与实验一相反。两个实验一致表明 ,无论是线索化阶段的注意 ,还是靶子加工阶段的注意 ,均对返回抑制有显著影响 ;并且 ,在对返回抑制的影响上 ,二者存在显著交互作用。从而支持注意影响返回抑制的观点。该结果对返回抑制的机制研究有一定意义。
