Inhibitory Control in Children with Frontal Infarcts Related to Sickle Cell Disease

Evidence from past studies indicates that children with traumatic brain injury experience difficulties with inhibitory control. Less is known about inhibitory control in children with frontal brain injury related to cerebral infarction. We compared the inhibitory performance of children with frontal infarcts related to sickle cell disease with that of a control group of children with sickle cell disease but no history of cerebral infarction. On a stimulus-response reversal task, children with frontal infarcts made significantly more accuracy errors in the inhibitory condition than controls. Findings from this study and from previous research suggest that impairments in inhibitory control are common following frontal injury in a range of pediatric populations.     

Assessing mental flexibility with a new word recognition test

This paper presents the development and preliminary evaluation of a new word recognition test (WRT) designed to measure individual differences in mental flexibility, defined as the ability to solve novel problems in unfamiliar settings. Conceptually designed to simulate problem solving in real world performance situations, the test was developed to recruit fluid and reproductive abilities and the interplay between convergent and divergent thinking. It is based on a framework that integrates and extends previous theoretical and methodological approaches to the study of cognitive ability and creative cognition. The WRT was administered with various cognitive ability and criterion measures to an undergraduate student sample (n = 266). Results provide preliminary evidence of construct validity. WRT scores correlated as expected with reference measures of cognitive ability, creative performance, and college performance (GPA). Regression analyses showed the WRT explained an additional 4.5% of variance in college performance over and above traditional cognitive ability measures that take up to five times as long to administer. Results suggest further study is warranted given the potential for its contribution to basic research and applied use.     

Psychometric properties of an experimental test for the assessment of basic arithmetic calculation efficiency / Propiedades psicométricas de una prueba experimental para la evaluación de la eficacia del cálculo aritmético básico

Abstract

In this article the ‘Arithmetic Calculation Efficiency Test’ (Test de Eficacia en el cálculo aritmético – TECA), a test for the assessment of arithmetic efficiency in terms of precision and speed in school-aged subjects, is introduced. The test aims to contribute to educational practices and the diagnosis of students who are at risk of Learning Difficulties in Calculations (LDC). Psychometric properties of the test items were analysed based on a sample of 331 subjects from grade 1 to 6 from Primary School. Analysis of content validity, item analysis, dimensionality and reliability have provided evidence of the validity of a one-dimensional structure consistent with the theoretical framework.     

A dualistic identity theory

Whilst it is accepted that humankind has been responsible for a considerable amount of environmental change, it is only recently that quantitative measures have been devised to express this. Such measures include a habitat index, the ecological footprint and the Living Planet Index. The applications and implications of these measures are discussed along with direct measures of changing atmospheric composition. All indicate that Europe is the most anthropogenically transformed continent and Australasia the least altered. In so far as a population increase of c. 36 per cent is likely to occur in the next 25 years, human induced environmental change is set to continue at a rapid pace. It is likely to be exacerbated by rapid industrialisation in some nations and increasing standards of living. Local, regional and international measures to curb environmental deterioration may temper this to a degree but new technologies e.g. biotechnology, may bring disadvantages as well as advantages.     

From a fixation on sports to an exploration of mechanism: The past,present, and future of hot hand research

We review the literature on the hot hand fallacy by highlighting the positive and negative aspects of hot hand research over the past 20 years, and suggesting new avenues of research. Many researchers have focused on criticising Gilovich et al.'s claim that the hot hand fallacy exists in basketball and other sports, instead of exploring the general implications of the hot hand fallacy for human cognition and probabilistic reasoning. Noting that researchers have shown that people perceive hot streaks in a gambling domain in which systematic streaks cannot possibly exist, we suggest that researchers have paid too much attention to investigating the independence of outcomes in various sporting domains. Instead, we advocate a domain-general mechanistic approach to understanding the hot hand fallacy, and conclude by suggesting approaches that might refocus the literature on the important general implications of the hot hand fallacy for human probabilistic reasoning.

Evaluation de la capacité de travail des seniors : l’apport des compétences perçues

The Work Ability Index (Ilmarinen, Tuomi, & Klockars, 1997; Ilmarinen, 2007) is a validated tool extensively used in epidemiological studies to measure older workers work ability. The WAI is relatively focused on health. The VOW/QFT (Hellemans, 2010, 2011, 2013) proposes to expand the notion of work ability with these competences, beyond the issue of functional ability. This contribution aims to test convergences and divergences between the WAI and the two work ability indices of the VOW/QFT, and also their respective predictors. Analyzes, conducted with 254 workers subject to medical visits, have shown especially that WAI scores and evolution of ability scores from the VOW/QFT are highly correlated, generally and among laborers, but not among employees. The results highlight the interest accounting for perceived competence for assessing work capacity among employees.     

New Waves in Philosophical Logic,edited by Greg Restall and Gillian Russell

Noël Blas Saenz has recently argued for a counterfactual condition on grounding called Sensitivity, with which he tries to show that there are no mereological sums and that universalism about composition is false. This reply argues, first, that, while Sensitivity may show that there are no mereological sums in Saenz’s idiosyncratic sense, this does not establish the failure of universalism and, second, that Sensitivity is false and ill-motivated in any case.     

The Contributions of Memory and Attention Processes to Cognitive Abilities

In two experiments, the contributions of memory and attention processes to the cognitive abilities of reasoning and perceptual speed were investigated. Two measures of speed of information retrieval from long-term and short-term memory (Posner paradigm, Sternberg paradigm) and two attention measures (continuous attention test, attention switching test) were included in the first experiment (N = 220). The memory tests led to correlations with the measures of cognitive abilities, whereas the attention test did not. The same tests as well as one additional memory test and one attention test (working memory test, test of covert orientation) were administered in the second experiment (N = 116). Again, the memory tests led to the larger correlations with the measures of cognitive abilities. Two components were obtained in components analysis, of which the first was characterized by high loadings of the memory tests and the second by high loadings of the attention tests. Only the memory component contributed to the prediction of cognitive abilities.
