Using Cognitive Mapping to Understand Problems Experienced by Family Caregivers of Persons with Severe Physical Disabilities

Individuals who provide ongoing care for family members who have a chronic disease or disability are likely to encounter a wide array of problems that can compromise their own health and their ability to function effectively in a caregiving role. Structured focus group meetings were conducted to elicit a comprehensive list of the problems that caregivers experienced during their first year of providing care to a person with a severe physical disability. A separate group of caregivers (N = 60) individually sorted problems into piles based on their similarity and assigned relative importance to each problem. The aggregated data were analyzed with multidimensional scaling and hierarchical cluster analysis. Results indicated that caregivers cognitively organize problems along three dimensions: I. Centeredness–caregiver versus patient-oriented; II. Relationship Demands–physical versus emotional; and III. Caregiver Burden–time versus emotional. Additionally, 6 clusters of substantively similar problems were identified and prioritized in terms of personal relevance: Basic Needs (lowest); Perceived Constraints; Caregiver Challenges; Patient Resentment; Patient Withdrawal; and Patient Intrapsychic Adjustment (highest). Further examination of the organization of problems identified by caregivers should provide important insights about the experience of caregivers and how more targeted interventions can be developed to address their specific needs.     

认知风格对不同类型几何问题解决的影响

通过镶嵌图形测验（EFT）,在初中学生中选了不同认知风格的被试,限时考查被试对不同类型几何问题的解决。结果表明：新问题与所学内容相似性会影响中学生几何问题解决的成绩;认知风格不同类型在几何问题解决中存在显著差异,在与所学内容相似性高的新问题解决中,场依存性学生的成绩显著地高于场独立性的学生。     

Psychometric Properties of the Grief Cognitions Questionnaire (GCQ)

Cognitive behavioral conceptualizations of complicated grief propose that negative cognitions play a core role in the development and persistence of emotional problems after bereavement, because they generate negative emotions and cause mourners to engage in counterproductive attempts to avoid the implications and the pain of the loss. To facilitate the assessment of potentially problematic cognitions after bereavement, the Grief Cognitions Questionnaire (GCQ) has been developed—a 38-item questionnaire representing 9 categories of cognitions. Building on a previous study that supported the reliability and validity of the GCQ, the current study further examined its psychometric properties, with data of 531 bereaved individuals who completed research questionnaires online through the Internet. Confirmatory factor analyses supported the nine-factor structure with 9 interrelated factors. The reliability and convergent and discriminative validity were found to be adequate. Altogether the GCQ seems to be a useful tool for the assessment of negative thinking after bereavement in research and clinical practice.     

Ontologies and Construals in Lexical Semantics

The purpose of this paper is to propose a framework of lexical meaning, broadly along the lines of Cognitive Semantics (Langacker 1987a). Within the proposed model, all aspects of meaning are to be explained in terms of properties of ontologies in conceptual space, i.e. properties of content ontologies and schematic ontologies and construals which are imposed on the conceptual structures on the occasion of use. It is through the operations of construals on ontological structures that different readings of lexical expressions arise. Lexical meanings are dynamic and sensitive to contextual demands, rather than fixed and stable. In a dynamic, usage-based model like this, polysemy and multiple readings emerge as a natural consequence of the human ability to think flexibly. Another more specific purpose of this paper is to draw attention to the usefulness of ontologies in linguistic research in general and semantic modelling in particular.     

Reacting aggressively to injustice at work: a cognitive stage model

The present article develops a cognitive stage model of workplace aggression, which contends that aggressive reactions to perceived injustice are cognitively construed following three cognitive steps that include the assessment stage, the accountability stage, and the decision stage. These three cognitive stages are essential in understanding victims’ retaliatory actions against perpetrators of injustices. The model’s implications for research and practice are discussed.     

Stereotypical thinking as a mediating factor in the association between exposure to terror and post-traumatic stress disorder symptoms among Israeli youth

Background and Objectives: The negative impact of exposure to terror on mental health, as well as on the perceptions of each side of the conflict toward the other, is well-documented. However, the association between stereotyping, concomitant with perceived threat, and anxiety, was rarely investigated. The current study examined information processing attributes and exposure to terror as predictors of PTSD symptoms among youth at inter-group conflict, with stereotypical thinking toward a threatening out-group as a possible mediator. Design: Cross-sectional, with exposure to terror, need for cognitive structure (NCS), efficacy at fulfilling the need for closure (EFNC) and self-esteem, predicting stereotypical thinking and PTSD symptoms. Method: Ninth graders (N?=?263) from two residential areas in Israel, varying in their degree of exposure to terror, responded to a self-report questionnaire tapping the above variables. Results: Stereotypical thinking was found to mediate the association between exposure to terror and PTSD symptoms, but not the association between the NCS and EFNC interaction and PTSD symptoms. Conclusions: The findings support terror management theory, so that a negative and rigid perception makes it difficult to construct coherent world-view, thus contributing to aggregation of existential anxiety and PTSD symptoms.     

认知抑制与人际宽恕:特质宽恕的调节作用

采用《特质宽恕量表》测量了102名大学生的特质宽恕能力,并通过Flanker任务和情景回忆法评估了被试的认知抑制和人际宽恕水平,目的是探讨特质宽恕、认知抑制与人际宽恕三者之间的关系。结果发现:(1)认知抑制、特质宽恕与人际宽恕各维度之间存在两两显著相关(除认知抑制与仁慈动机之外);(2)特质宽恕对回避、报复和仁慈动机均具有预测作用,而认知抑制则只对报复动机具有预测作用;(3)特质宽恕与认知抑制对回避动机具有负向的调节作用,对仁慈动机具有正向的调节作用。     

Reducing Measurement Error in Student Achievement Estimation

The achievement level is a variable measured with error, that can be estimated by means of the Rasch model. Teacher grades also measure the achievement level but they are expressed on a different scale. This paper proposes a method for combining these two scores to obtain a synthetic measure of the achievement level based on the theory developed for regression with covariate measurement error. In particular, the focus is on ordinal scaled grades, using the SIMEX method for measurement error correction. The result is a measure comparable across subjects with smaller measurement error variance. An empirical application illustrates the method.     

An Invitation to Behavior Analysts: Review of in Search of Memory: The Emergence of A New Science of Mind by Eric R. Kandel

This fascinating autobiography and multifaceted case history in neuroscience research is accessible to laymen and potentially instructive to working scientists. Kandel takes the reader through his thought processes as he describes experiments that led to some of the past decades'' major neuroscience discoveries (some highlights of which are summarized in the review''s Appendix), and eventually to his Nobel Prize. The review analyzes some of the terminological and conceptual issues that have often inhibited communication between behavior analysts and neuroscientists, with special attention to some of Bennett and Hacker''s admonitions viewed from the perspective of language evolution and linguistics. The review then discusses opportunities for behavior analysts to collaborate with neuroscientists by applying behavioral contingency analysis to help specify the independent variables of neuroscience experiments described by Kandel. Finally, it examines Kandel''s provocative heuristics for locating important research problems, and the lessons that can be gleaned from the book regarding the attributes of potentially great achievers.
