Background/Objective: Continuous Performance Tests (CPTs) have demonstrated validity when differentiating children with ADHD from healthy controls. However, these CPTs have limitations such as low ecological validity. New CPTs based on the use of Virtual Reality (VR) have appeared as supposedly improved methods for assessing ADHD. This study aims to compare the discriminant value of attentional variables produced by a VR CPT (Aula Nesplora) with that of variables from a traditional CPT (Test of Variables of Attention; TOVA) for identifying ADHD. Method: A total of 338 children aged between 6 and 16 years old (M = 10.84, SD = 3.01) participated in the study: 31.95% correspond to the inattentive presentation, 15.38% to the impulsive-hyperactive presentation, 22.78% to the combined presentation, and the remaining 29.88% correspond to children without ADHD. Results: Results indicated that Aula Nesplora predicts ADHD presentations better than TOVA. It also differentiates better between ADHD and non-ADHD students. Conclusions: These findings show the potential advantages of using virtual reality in ADHD assessment, as it facilitates the diagnosis of ADHD and the differentiation of its presentations in a realistic environment.  相似文献

This study tests the factor structure, measurement invariance, and correlates of the Childhood Executive Functioning Inventory (CHEXI) with a large and diverse sample of 3- to 5-year-olds (n = 844). Consistent with previous studies, a two-factor model that distinguishes working memory from inhibition provides the best fit to the observed data. This two-factor model has been shown to demonstrate strong measurement invariance for different subgroups of children (boys vs. girls, high vs. low income). Whereas boys tend to have greater working memory and inhibition difficulties (Cohen’s d = 0.15 and 0.20, respectively), children from low-income households tend to have more working memory problems than their peers from high-income households (Cohen’s d = 0.25). Finally, correlations between CHEXI scores, examiner reports of child behavior, and child performance on a battery of executive function (EF) tasks were investigated. CHEXI scores were found to be more consistently related to examiner reports of child behavior than child performance on EF tasks. Tthe strengths and weaknesses of the CHEXI as a questionnaire measure of EF are discussed, and directions for future research are suggested.  相似文献

Abstract

Cognitive stimulation programs are widely used as a preventive tool for cognitive decline in older adults, as they can favour positive ageing by maintaining older persons’ autonomy and preserving their cognitive functions. Because of this, and due to its potentially easy application on a large scale and at a low cost, the incorporation of technologies for the cognitive stimulation of older adults has become an area of growing interest. This review outlines the advantages and disadvantages of computer-based cognitive stimulation programs aimed at healthy older adults, focusing on aspects that influence their effectiveness and future direction. Twenty-five articles were considered, including original studies, literature reviews and meta-analyses, published between 2013 and 2017. It was concluded that there is a need to generate more randomized studies with active control groups to assess the effectiveness of cognitive stimulation through computer-based programs, as well as develop designs to establish strategies that increase older adults’ adherence and ensure their motivation to carry out these activities.  相似文献

While there are studies that describe early syntactic development, less research has focused on oral syntactic development in Spanish throughout schooling according to text structure. This article describes syntactic patterns in Chilean school age students and compares the differences between narrative and expository discourse. The oral production of 462 students aged 5–18 years old from eight schools in a central Chilean region was analysed. Their oral productions were transcribed and segmented at clause and clause package levels; clause package length, clause package density and the clause density were calculated. Results show that students are more productive and construct more complex syntactical discourse as they advance through their education. The results also suggest that syntactic development patterns function differently in narrative and expository discourses. This indicates that students firstly master their syntactic resources before producing narratives. In addition, the implications of using different syntactic measures to describe syntactic development by text structure are explored.  相似文献

In two experiments, the impact of faking on the affect misattribution procedure (AMP) was examined. Results revealed that faking influences both the overall means and the convergent validity of AMP effects in terms of correlations with self-report measures. Faking effects were very selective in that they affected fake-prime trials only, for which AMP effects were significant, but reversed in direction, while AMP effects for non-fake trials remained intact. Importantly, neither strategic advice nor prior task experience was a necessary prerequisite for successful faking. The discussion focuses on possible processes underlying successful faking in the AMP.  相似文献

To date, there is a lack of satisfactory inferential techniques for the analysis of multivariate data in factorial designs, when only minimal assumptions on the data can be made. Presently available methods are limited to very particular study designs or assume either multivariate normality or equal covariance matrices across groups, or they do not allow for an assessment of the interaction effects across within-subjects and between-subjects variables. We propose and methodologically validate a parametric bootstrap approach that does not suffer from any of the above limitations, and thus provides a rather general and comprehensive methodological route to inference for multivariate and repeated measures data. As an example application, we consider data from two different Alzheimer’s disease (AD) examination modalities that may be used for precise and early diagnosis, namely, single-photon emission computed tomography (SPECT) and electroencephalogram (EEG). These data violate the assumptions of classical multivariate methods, and indeed classical methods would not have yielded the same conclusions with regards to some of the factors involved.  相似文献

Although global self-esteem has historically been assumed to be a unidimensional construct, recent theory and research has challenged this assumption. Instead, it has been suggested that self-esteem might more fruitfully be viewed as a two-dimensional construct composed of: (a) self-liking, based on our perceptions of feedback from our social environment; and (b) self-competence, based on our internal conceptions of success and failure in performing tasks. The Self-Liking and Competence Scale (SLCS) is a self-esteem measure that has recently been developed based on this two-dimensional conceptualization of self-esteem. The purpose of the present research was to validate a Norwegian translation of the SLCS. 372 participants were given a translated version of the SLCS, and the translated scale exhibited psychometric properties similar to those of the original English version of the scale.  相似文献

To provide a measure of the Big Five for contexts in which participant time is severely limited, we abbreviated the Big Five Inventory (BFI-44) to a 10-item version, the BFI-10. To permit its use in cross-cultural research, the BFI-10 was developed simultaneously in several samples in both English and German. Results focus on the psychometric characteristics of the 2-item scales on the BFI-10, including their part-whole correlations with the BFI-44 scales, retest reliability, structural validity, convergent validity with the NEO-PI-R and its facets, and external validity using peer ratings. Overall, results indicate that the BFI-10 scales retain significant levels of reliability and validity. Thus, reducing the items of the BFI-44 to less than a fourth yielded effect sizes that were lower than those for the full BFI-44 but still sufficient for research settings with truly limited time constraints.  相似文献

While Michael Walzer's distinction between preemptive and preventive wars offers important categories for current reflection upon the Bush Doctrine and the invasion of Iraq, it is often treated as a modern distinction without antecedent in the classical Christian just war tradition. This paper argues to the contrary that within Augustine's corpus there are passages in which he speaks about the use of violence in situations that we would classify today as preemptive and preventive military action. While I do not claim that Augustine makes an explicit distinction between the two types of war (such would be anachronistic), I will argue that based on examinations of De libero arbitrio I.v.11–12 and De civitate Dei I.30 Augustine's discussions of hypothetical cases or actual wars in history provide insights helpful for contemporary reflection on preemptive and preventive wars.  相似文献
