基于特征的联想

联想是认知科学中十分重要的现象,许多学者进行过不同角度的研究,获得了许多有意义的结果。根据有关对象（０ｂｊｅｃｔ）描述的基本概念,从联接机制的角度对联想问题进行一些探讨,并提出一个基于特征的联想模型ＦＢＣＡＭ（ＦｅａｔｕｒｅＢａｓｅｄＣｏｎｎｅｃｔｉｏｎｉｓｔＡｓｓｏｃｉａｔｉｏｎＭｏｄｅｌ）。在ＦＢＣＡＭ中,对象由其特征及特征的伴随值描述,从而可以获得更为精确的描述。对象的全部特征构成描述模式,伴随值则相应地构成伴随向量。在此基础上可以细致地刻画概念之间的相似性,并可对联想及注意机制进行细致的模拟与分析。文中利用联接机制的思想实现了ＦＢＣＡＭ并给出该系统的部分运行结果,表明ＦＢＣＡＭ可以较合理地解释联想过程     

Multivariate normal integrals and contingency tables with ordered categories

Ak-dimensional multivariate normal distribution is made discrete by partitioning thek-dimensional Euclidean space with rectangular grids. The collection of probability integrals over the partitioned cubes is ak-dimensional contingency table with ordered categories. It is shown that loglinear model with main effects plus two-way interactions provides an accurate approximation for thek-dimensional table. The complete multivariate normal integral table is computed via the iterative proportional fitting algorithm from bivariate normal integral tables. This approach imposes no restriction on the correlation matrix. Comparisons with other numerical integration algorithms are reported. The approximation suggests association models for discretized multivariate normal distributions and contingency tables with ordered categories.The contingency-table approach occurred to me while I was collaborating with Paul Holland of the Educational Testing Service in 1985 on bivariate dependence functions. Holland maintains a belief that the continuous can learn from the discrete. This work is a reassertion of his claim.This research was sponsored by the National Science Council, Republic of China.     

Tail-measurability in monotone latent variable models

We consider latent variable models for an infinite sequence (or universe) of manifest (observable) variables that may be discrete, continuous or some combination of these. The main theorem is a general characterization by empirical conditions of when it is possible to construct latent variable models that satisfy unidimensionality, monotonicity, conditional independence, andtail-measurability. Tail-measurability means that the latent variable can be estimated consistently from the sequence of manifest variables even though an arbitrary finite subsequence has been removed. The characterizing,necessary and sufficient, conditions that the manifest variables must satisfy for these models are conditional association and vanishing conditional dependence (as one conditions upon successively more other manifest variables). Our main theorem considerably generalizes and sharpens earlier results of Ellis and van den Wollenberg (1993), Holland and Rosenbaum (1986), and Junker (1993). It is also related to the work of Stout (1990).The main theorem is preceded by many results for latent variable modelsin general—not necessarily unidimensional and monotone. They pertain to the uniqueness of latent variables and are connected with the conditional independence theorem of Suppes and Zanotti (1981). We discuss new definitions of the concepts of true-score and subpopulation, which generalize these notions from the stochastic subject, random sampling, and domain sampling formulations of latent variable models (e.g., Holland, 1990; Lord & Novick, 1968). These definitions do not require the a priori specification of a latent variable model.The authors made equivalent contributions to the results of this article.

The analysis of three-way contingency tables by three-mode association models

TheRC(M) association model (Goodman, 1979, 1985, 1986, 1991) is useful for analyzing the relationship between the variables of a 2-way cross-classification. The models presented here are generalizations of theRC(M) association model for 3-way tables. The family of models proposed here, 3-mode association models, use Tucker's 3-mode components model (Tucker, 1964, 1966; Kroonenberg, 1983) to represent either the three factor interaction or the combined effects of two and three factor interactions. An example from a study in developmental psychology (Kramer & Gottman, 1992) is provided to illustrate the usefulness of the proposed models.I thank Stanley Wasserman, Laurie Kramer, Ulf Böckenholt, Larwence Hubert, Jeffrey Tanaka, and five anonymous reviewers for valuable comments.     

Measures of interobserver agreement: Calculation formulas and distribution effects

Seventeen measures of association for observer reliability (interobserver agreement) are reviewed and computational formulas are given in a common notational system. An empirical comparison of 10 of these measures is made over a range of potential reliability check results. The effects on percentage and correlational measures of occurrence frequency, error frequency, and error distribution are examined. The question of which is the best measure of interobserver agreement is discussed in terms of critical issues to be considered     

Behavioral correlates of self-control at 33 months

Self-control behavior of 48 33-month-old children was examined during two delay-of-gratification tasks. Children were categorized as high, medium, and low in self-control on the basis of their cumulative delay time. Instances of attention shifts, body movements, as well as social and object-referencing were coded throughout the two delay periods. Results showed significant group differences in behavioral tactics. Children in the low group looked at and touched the forbidden object more often; members of the medium group used more social referencing, and those in the high group were more likely to reference nonforbidden objects. Findings also suggested that high controllers were more likely to use self-distraction tactics involving shifts in attention from one object to another during the delay period. Separate analyses for each task indicated that the observed delay tactics were stable from one context to the other. These findings substantiate results from other research on self-control with 3-year-old children and also document different behavioral styles of self-regulation during delay of gratification.     

父母情绪调节困难对流动儿童对立违抗症状的影响:亲子冲突解决方式和儿童情绪调节的作用

本研究以来自北京10所小学的369名有对立违抗(Oppositional Defiant Disorder, ODD)症状的流动儿童及父母、349名无ODD症状的对照组流动儿童及父母为被试进行了问卷施测,探究了父母情绪调节困难对流动儿童对立违抗症状的影响,并进一步探讨了亲子冲突解决方式和儿童情绪调节(情绪调节与情绪消极和不稳)在其中所起的作用。经过分析发现:(1)ODD症状流动儿童的父母情绪调节、亲子冲突解决方式、儿童情绪调节显著差于对照组儿童;(2)总体上,父母情绪调节困难、亲子冲突解决方式和儿童ODD症状之间两两相关显著,而儿童情绪调节与这几个变量相关不显著;(3)父母情绪调节困难能显著正向预测流动儿童ODD症状,并进一步通过亲子冲突解决方式对流动儿童ODD症状产生影响;(4)儿童情绪调节(儿童情绪调节与儿童情绪消极和不稳)仅在父母情绪调节困难对儿童ODD症状的直接影响中起着显著的调节作用,对亲子冲突解决方式所起的中介作用并无调节作用。在对有ODD症状的流动儿童进行干预时,不仅要培养儿童自身的情绪调节能力,也应提升父母的情绪调节能力并改善亲子冲突解决方式。     

辛苦所得与意外所得的非理性消费偏差：基于IAT检测和ERP证据

不同来源的财富因其在人们心理的权重差异会导致对其消费态度与方式的不同。前人运用一系列行为实验已发现意外所得更容易消费、辛苦所得则不容易消费。基于心理账户和内隐社会认知等理论, 运用IAT和ERP考察财富的意外所得与辛苦所得在人们心理引起的内在消费偏差, 进而对内隐消费态度和脑加工机制进行间接检测。IAT研究结果表明, 意外所得与容易消费的联结更加紧密, 辛苦所得与不易消费的联结更加紧密, 从内隐层面验证了前人的行为研究结论; ERP研究结果发现辛苦所得与意外所得这两个不同收入来源可能建立了不同脑加工机制, 且在P3和LPC成分得到反映, P3成分可能是反映辛苦所得组偏好难消费型消费方式的ERP成分, LPC反映了意外所得收入条件下个体偏好易消费型消费方式的特点。     

工读学生与普通学生对责任判断的比较研究

用内隐联想测验对40名工读学生与普通学生的责任判断进行比较研究,结果表明:工读学生比普通学生辨别攻击词以及与"责任在他"有关的短语的反应时短;工读学生辨别与"责任在他"有关的短语的速度比辨别与"责任在我"有关的短语的速度快,而普通学生辨别与"责任在他"有关的短语的速度比辨别与"责任在我"有关的短语的速度要慢;工读学生在"责任在他—攻击,责任在我-不攻击"的联合辨别反应时上比普通学生短。这些反应时的差异反映了工读学生存在着敌意归因与对攻击信念的内隐联想。     

Opening to the otherwise: The discipline of listening and the necessity of free‐association for psychoanalytic praxis

It is argued that only free‐association methodically opens the discourse of self‐consciousness (the representations available to reflective awareness) to the voicing of the repressed. The method is key to Freud's originality and the sine qua non of any genuinely psychoanalytic process. Clinical procedures which do not prioritize a steadfast and ongoing commitment to this method (instead emphasizing either interpretative formulations, as decisive acts that appear to fix and finalize the meaning of a particular lived experience, or the vicissitudes of transference‐countertransference in the immediate treatment situation) all too readily entrap the treatment, limiting its capacity to divulge the power of unconscious processes. Influenced by Laplanche, Freud's 1920 principles of lifefulness and deathfulness (the binding and unbinding of psychic energy in representations) facilitate an understanding of the unique significance of free‐associative discourse in opening the representational textuality of self‐consciousness to the voicing of that which is otherwise than representationality and reason. The ‘otherwise’ is intimated as the returning force of the repressed, as the ‘unfathomable navel’ of ‘thing‐presentations,’ experienced and expressed within the text of awareness, yet not translatable into the law and order of its logical and rhetorical reflections. Free‐associative discourse thus affects self‐consciousness in a way that is radically different from other creative procedures (‘psychosynthetic’ or integratively interpretive). In this respect, the status of free‐associative praxis as necessary for a genuinely psychoanalytic process is justified.
