不同智商儿童和唐氏综合症儿童的关联性负变(CNV)

比较不同智商正常儿童和唐氏综合症(Down’s Syndrome)儿童的关联性负变(Contingent Negative Variation CNV)。结果是:智力缺陷儿童的CNV幅度明显下降甚至缺失。智力较高儿童CNV较大,CNV的晚成分与智商,尤其是言语智商密切相关,智商和言语智商越高,晚成分幅度越大。似乎晚成分更能反映人的语言方面的能力。早成分则与语言、操作以及全量表智商都无明显关系。     

Who Uses the Cost-Benefit Rules of Choice? Implications for the Normative Status of Microeconomic Theory

We find three factors to be associated with use of cost-benefit rules in everyday decisions. These are effectiveness in achieving desirable life outcomes, intelligence, and training in economics. We argue that these empirical findings support the claim that cost-benefit reasoning is normative.     

人类颜色视觉的计算理论

该文有机地结合了计算视觉理论和生态学视觉理论,指出颜色信息处理的根本任务是检测环境中的光不变量。在此基础上,作者提出了颜色视觉的计算理论以及计算理论本身的生物学标准。初级视觉计算是典型的不适定问题,动物的视觉系统则利用视环境中存在的条件将该不适定问题转化为定解问题。本文引入颜色视觉计算的免要条件,客观性约束,以及颜色认知的神经表象,证明了上述约束下颜色算法的存在性。本文给出了构造颜色知觉的基本假设。同时,该文还讨论了与上述问题密切相关的几个基本问题:神经表象的完备性,主观色觉的客观性,明度知觉和颜色知觉的统一,人类主观色觉的实现方式。     

Enhancing Consultee Problem-Solving Skills in Consultative Interactions

Selected empirical research on consultative problem solving is reviewed. Although there is general support for the effectiveness of consultation in resolving a variety of presenting problems and in improving consultees' skills for solving future problems, there is a need for additional methods to facilitate the process. Direct training of consultees in behavior management, communication, and consultation process skills is advocated as one means of attaining this goal.     

Standards for Organizational Consultation Assessment and Evaluation Instruments

Although consultation researchers and practitioners have called attention to the need for more psychometrically sound instruments, little advancement has occurred in this area. The authors outline key quantitative and qualitative psychometric standards for organizational consultation assessment and evaluation instruments. In addition, a framework and review of several existing questionnaires are presented. Implications for instrument use by practitioners and suggestions for further research are discussed.     

The concurrent validity of three self-report measures of borderline personality

The recent accumulation of self-report measures of borderline personality disorder (BPD) affords the opportunity to evaluate both the construct validity of the concept and the quality of these measures. This study examines the relationship among three recently developed self-report instruments for assessing BPD from the Personality Assessment Inventory (PAI; Morey, 1991), the MMPI Personality Disorders Scales (MPD; Morey, Waugh, & Blashfield, 1985), and the Bell Object Relations Inventory (BORI: Bell, Billington, & Becker, 1986). Data on the three measures were provided by 119 undergraduate subjects from a southeastern university. A correlational analysis addresses the convergence of these measures of BPD, their divergence from measures of different but related traits, and their independence from variance due to method. Application of the Campbell-Fiske (1959) criteria indicates adequate convergence for all the BPD measures but a lack of discriminant validity for the BORI scales. The fit of the data to a structural model of construct validity is tested using confirmatory factor analysis, and these results are consistent with the hypothesis of a latent borderline trait factor independent of measurement method factors. In sum, the construct validity of the borderline personality concept using self-report methodologies receives support, and a strong association between borderline personality and paranoid phenomena is also suggested.     

Research in Consultation: Toward Better Analogues and Outcome Measures

Recommendations for improving consultation research include (a) strengthening consultation analogue research by incorporating “boundary” conditions into research designs and (b) extending the outcome measures used.     

Grandparents Affected by Parental Divorce: A Population at Risk?

When parents divorce, grandparents who have bonded with grandchildren may be affected, particularly when denied visitation. In this article the author reviews normative aspects of grand-parenthood and how grandparents are affected by parental divorce. Legal and ethical issues and counseling interventions are discussed.
