The ability to enact cognitive control under changing environmental demands is commonly studied using set-shifting paradigms. While the control processes required for task set reconfiguration (switch costs) have been studied extensively, less research has focused on the control required during task repetition in blocks containing multiple tasks as…

Clinical cognitive ability assessment--and its corollary, score interpretation--are in a state of disarray. Many current instruments are designed to provide a bevy of scores to appeal to a variety of school psychologists. These scores are not all grounded in the attribute's theory or developed from sound measurement or psychometric theory. Thus,…

The development of intellectual capital at the macro- and mesoscale is the main tool for the transition of the economy to a progressive sixth technological mode, and at the level of an individual organization it ensures its stable position and high competitiveness in the market. However, training and educating its applications are of a great…

As spatial languages, sign languages rely on spatial cognitive processes that are not involved for spoken languages. Interlocutors have different visual perspectives of the signer's hands requiring a mental transformation for successful communication about spatial scenes. It is unknown whether visual-spatial perspective-taking (VSPT) or mental…

Truncating variants of the "MAGEL2" gene, one of the protein-coding genes within the Prader-Willi syndrome (PWS) critical region on chromosome 15q11, cause Schaaf-Yang syndrome (SYS)--a neurodevelopmental disorder that shares several clinical features with PWS. The current study sought to characterize the neurobehavioral phenotype of SYS…

An assessment of graphic literacy was developed by articulating and subsequently validating a skills-based cognitive model intended to substantiate the plausibility of score interpretations. Model validation involved use of multiple sources of evidence derived from large-scale field testing and cognitive labs studies. Data from large-scale field…

Prior research has demonstrated that linguistic skills and knowledge contribute to successful reading acquisition. In contrast, little is known about the influence of domain-general learning abilities on reading. To investigate associations between general memory functions and reading during the early stages of learning to read, performance…

Appropriate interpretation of assessment data requires an appreciation that tools are subject to measurement error. School psychologists recognize, at least on an intellectual level, that measures are imperfect--that test scores and other quantitative measures (e.g., rating scales, systematic behavioral observations) are best estimates of…

To determine whether a gluten-free diet (GFD) compared with a gluten-containing diet (GD) influences functioning of children with autism spectrum disorders (ASD), we performed a randomized, controlled, single-blinded trial. Sixty-six children (36-69 months) with ASD, within the normal IQ (> 70) range, who had been on a GFD for at least 8 weeks…

As executive functioning (EF) is especially sensitive to age-related cognitive decline, EF was evaluated by using a multi-method assessment. Fifty males (60-85 years) with a late adulthood autism spectrum condition (ASC) diagnosis and 51 non-ASC males (60-83 years) were compared on cognitive tests across EF domains (cognitive flexibility,…

William's Syndrome (WS) is a rare neurodevelopmental disorder caused by a genetic abnormality, affecting about 1 in 10,000 people worldwide. While there are some behavioral similarities between WS and other high incidence disabilities, such as autism, several unique physical, cognitive, and behavioral characteristics are expressed in individuals…

Attrition of anatomy knowledge has been an area of concern in health professions curricula. To ensure safe and effective clinical practice, the study of chiropractic requires a good knowledge of musculoskeletal anatomy. In this study, musculoskeletal limb knowledge retention was investigated among students in the 5-year chiropractic program at…

One of the overriding hopes of the Down syndrome (DS) research community is to arrive at a better understanding of how trisomy 21 affects brain development and function, and that doing so will improve quality of life and independence for people with DS. In searching for the underlying causes of intellectual disability in DS, researchers and…

Background: The need to focus more on children's abilities to change requires new assessment technologies in education. Process-oriented assessment can be useful in this regard. Dynamic testing has the potential to provide in-depth information about children's learning processes and cognitive abilities. Aim: This study implemented a…

The current study was designed to examine the relationship between cognitive ability and player experience in shaping how players think within, and acclimate to, video games as complex systems. Specifically, researchers examined the relationship between player's cognitive ability and gameplay outcomes within a video game (i.e., The Deed). Outcomes…
