Test of visuospatial construction: Validity evidence in extremely low birth weight and late preterm children at early school age

The Test of Visuospatial Construction (TVSC), a measure of visuoconstruction that does not rely on upper extremity motor response or written production, was administered to extremely low birth weight (ELBW), late preterm (LPT), and term participants at preschool (n = 355) and kindergarten (n = 265) ages. TVSC showed statistically significant weak-to-moderate positive correlations (age 3: r = .118–.303; age 6: r = .138–.348) with Developmental VMI, Differential Ability Scales-II Copying, Matrices, and Pattern Construction subtests, Baron-Hopkins Board Test, and the Purdue Pegboard. One-way ANOVA indicated ELBW performed worse than Term (p = .044) on visuospatial construction at age 3 with a small-to-medium effect size (d = ?0.43). No other statistically significant differences were found at age 3 on the TVSC (ELBW/LPT: p = .608, d = ?0.17; LPT/Term: p = .116, d = ?0.31). At age 6, ELBW participants performed worse than LPT participants (p = .027) and Term participants (p = .012); LPT participants did not differ from Term participants. Small effect sizes at age 3 (ELBW < LPT, d = ?0.17; ELBW < Term, d = ?0.43) were notably larger at age 6 (ELBW < LPT, d = ?0.42; ELBW < Term, d = ?0.53). Important practical differences showing LPT participants performed below Term participants (d = ?0.31) at age 3 were no longer evident at age 6 (d = ?0.097). These findings provide preliminary evidence of TVSC validity supporting its use to detect neuropsychological impairment and to recommend appropriate interventions in young preterm children.     

The Mullen scales of early learning: ceiling effects among preschool children

Two cognitive tests were administered to typically developing children (36–67 months): the Mullen Scales of Early Learning (MSEL), which is appropriate for very young children and thus often used in research with atypical samples (e.g., children with Autism Spectrum Disorder), and the Kaufman Assessment Battery for Children (K-ABC). This was done in order to re-examine possible MSEL ceiling effects in a new sample and achieve a more in-depth understanding of these ceiling effects, if indeed present. Results indicated that among children ranging in age from 51 to 68 months, MSEL scores were significantly lower than K-ABC scores, and that with increasing age the number of children who completed the MSEL without establishing a ceiling level increased. Our results indicated that the MSEL scores are affected by ceiling effects and, therefore, the test underestimates cognitive abilities among older and more cognitively able children.     

Assessment sensitivity in legal discourse

We explain three phenomena in legal discourse in terms of MacFarlane’s assessment-sensitive semantics: incompatible applications of law, assessments of statements about what is legally the case, and retrospective overruling. The claim is that assessment sensitivity fits in with the view, shared by many legal theorists at least with respect to hard cases, that the final adjudicator’s interpretation of legal sources is constitutive of the applied norm. We argue that there are strong analogies between certain kinds of statements in legal discourse as understood in light of that view and discourse about matters of taste and future contingents. Thus, if assessment-sensitive semantics provides a compelling account of discourse about matters of taste and future contingents, then it likewise provides a compelling account of those statements in legal discourse.     

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.
