Depression: Psychological Referrals in Nursing Homes

Studies in nursing homes have consistently shown the presence of mental health disorders. We assessed 300 nursing home residents (referred for psychological testing) to provide preliminary data on referral patterns, assess the cognitive and affective patterns of residents with different diagnoses, and present psychometric data on depression measures, including the Beck Depression Scale (BDI) (as a bivariate index) and the Mood Scale (a shortened version of the Geriatric Depression Scale). Results show that the referrals involved a compromised group of residents, both cognitively and affectively. Despite obvious mean differences, a MANOVA revealed that Major Depressive Disorder did not differ significantly from the Adjustment Disorder and Dementia groups on the bivariate BDI and Mood Scale; the dementia group was lower than the depression and adjustment groups on the MMSE. Patterns on depression inventories also identified a correct classification score of 4 on the BDI (89%) and 3 on the Mood Scale (79%). Discussion endorsed use of the bivariate BDI and addressed depression in these facilities.     

应对行为跨文化测评的构念等同与偏差性研究

本文对COPE量表测评我国大学生应对行为方式的构念等同与偏差性进行深入探讨。采用验证性因素分析的方法测试了原版量表(COPE)及其中文修订本(C-COPE)的不同因素结构模型与465名大学生测评数据的拟合优度。研究结果支持C—COPE的测评维度结构,表明COPE量表对我国人群所进行的应对测评与西方社会的相比确实存在跨文化构念不等同性或偏差性,两者测评结果的跨文化比较因此缺乏必要前提条件。文中对所发生的构念偏差现象进行了详细分析。     

Effects of novel odors on intermale attack behavior in mice

Offensive, defensive, and nonagonistic social behaviors of resident male mice toward unfamiliar intruders were examined during exposure to the novel odors of chocolate or sheep's wool. Both novel odors reduced lateral attacks and boxing when compared to familiar sawdust odor. Chocolate, but not sheep's wool, also reliably increased flight behavior by residents. Neither social behaviors nor self-grooming were affected by these odors. The novel odors had no effect upon, or actually decreased, the defensive responses of intruders towards residents. The equivalent effectiveness of both predator and nonpredator odors in elevating risk assessment and suppressing attack during firsttime exposure, and the decreased potency of cat odors following repeated exposure, suggests that novelty contributes to the enhanced defensiveness seen among subjects during initial exposure to predator odors. © 1995 Wiley-Liss, Inc.     

Arguments in the practical reasoning underlying constructed probability responses

Reasoning is an important cognitive activity in probability assessment, and one that has been understudied. This proposition motivates the paper's three general aims. First, based on research in rhetoric, we present a theoretical means of analyzing the arguments constructed during the reasoning that occurs in probability assessment. Second, from verbal protocol data, we establish that subjects constructed arguments in forming beliefs and assessing the associated probabilities. Third, we analyze the data for the structure of subject's arguments, including argument content and form. Subjects used a limited amount of relevant evidence and used a variety of argument forms that could be characterized by the nature of the knowledge that subjects brought to bear in forming the arguments. Subjects predominantly used causal reasoning, but also employed hierarchical category knowledge, resemblance relationships, and arguments from authority. These findings form a basis for expanding our accounts of probability assessment and for improving assessment practice.     

Probability judgment accuracy for general knowledge. Cross-national differences and assessment methods

In this study we compare the probability judgment accuracy of subjects from the United States and Turkey. Three different response modes were employed — numerical probabilities, pie diagrams, and odds. The questions employed in the study were restricted to two-alternative, general-knowledge items. The observed pattern of differences in the components of probability judgment accuracy paralleled those of studies that have compared Western and Asian subjects. In particular, Turkish subjects exhibited better discrimination but worse calibration than their US counterparts. This result persisted across all three response modes. These findings lend support to previous assertions that observed cross-national differences arise from socioeconomic rather than Asian versus Western cultural differences. However, the consistency of the observed differences across response modes refutes a previous assertion that observed cultural differences are merely the result of response bias.     

Adaptive non-interventional heuristics for covariation detection in causal induction: model comparison and rational analysis

In this article, 41 models of covariation detection from 2 × 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in covariation detection (McKenzie & Mikkelsen, 2007) and data selection (Hattori, 2002; Oaksford & Chater, 1994, 2003). The results were supportive of the new model. To investigate its explanatory adequacy, a rational analysis using two computer simulations was conducted. These simulations revealed the environmental conditions and the memory restrictions under which the new model best approximates the normative model of covariation detection in these tasks. They thus demonstrated the adaptive rationality of the new model.     

母亲评价与幼儿数学认知发展的关系

母亲对幼儿数学能力的评价是母亲教育观念的重要组成部分。研究运用问卷法与个别测查法,考察母亲对子女数学能力的评价与幼儿数学认知能力,并通过二者的一致程度揭示母亲评价其子女数学能力的准确性。研究发现,母亲对子女数学能力的评价存在明显的高估倾向;与母亲受教育水平及子女性别等因素不同,子女前期的数学成绩对母亲评价其数学能力的准确性存在显著影响;母亲对子女数学能力评价的准确性与子女数学认知发展水平存在显著的正相关,适当的高估对子女未来数学认知的发展最为有利     

Establishing and Evaluating the Substantive Adequacy of Positive Behavioral Support Plans

The Individuals with Disabilities Education Improvement Act (2004) renewed the commitment to provide positive behavioral support (PBS) for students that engage in persistent problem behavior. Behavior intervention plans (also known as PBS plans) serve as legal documents that help guide the implementation of intervention strategies to encourage more positive forms of behavior. The purpose of this study was to evaluate the substantive adequacy of PBS plans developed for special education students. This was accomplished by documenting the content of plans developed by two different groups of educators using a rating instrument based on the key concepts of PBS planning. Results revealed that the majority of plans developed by teams without identified training and expertise in PBS were rated as substantively inadequate, lacking critical information related to effective behavioral support planning. The implications of the results for everyday practice in the schools and directions for future research are discussed.     

A Bayesian view of covariation assessment

When participants assess the relationship between two variables, each with levels of presence and absence, the two most robust phenomena are that: (a) observing the joint presence of the variables has the largest impact on judgment and observing joint absence has the smallest impact, and (b) participants' prior beliefs about the variables' relationship influence judgment. Both phenomena represent departures from the traditional normative model (the phi coefficient or related measures) and have therefore been interpreted as systematic errors. However, both phenomena are consistent with a Bayesian approach to the task. From a Bayesian perspective: (a) joint presence is normatively more informative than joint absence if the presence of variables is rarer than their absence, and (b) failing to incorporate prior beliefs is a normative error. Empirical evidence is reported showing that joint absence is seen as more informative than joint presence when it is clear that absence of the variables, rather than their presence, is rare.     

Capturing worry in daily life: are trait questionnaires sufficient?

Worry is crucial in the development and maintenance of anxiety disorders and has been associated with several other adverse health outcomes. Yet, little is known about the frequency and perseveration of worry in daily life, and its predictability by widely used trait questionnaires. In this study 432 students completed the Penn State Worry Questionnaire (PSWQ), the Worry Domains Questionnaire (WDQ) and the State-Trait Anxiety Inventory-Trait version (STAI-T) and kept a log of worry frequency and duration during six consecutive days and nights. The results showed that worry is a very common phenomenon that is predicted by the two trait worry questionnaires, independent of trait anxiety. The often clinically utilized PSWQ predicted worry duration better than the WDQ, and exclusively predicted night-time worry and several other indices of perseverative and potentially pathogenic worry. Although this study provides some support for the predictive validity of the PSWQ and the WDQ, these questionnaires did not account for the larger part of variance in daily worry. Future studies of worry and its associated perseverative processes should consider using momentary assessments.
