Background: Right hemisphere brain damage (RHD) can cause challenges with information gathering. Cognitive processes aid in implicit and explicit information gathering, yet the relationship between these processes and question-asking, the most explicit avenue of information gathering, has not been explored. The purpose of this exploratory…

Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…

The block design task (BDT) is a visuospatial measure that individuals with Williams syndrome (WS) perform poorly on. However, it is unclear what underlies their impaired performance. This study investigated whether poorer performance is a result of visuospatial difficulties, executive function (EF) difficulties, atypical looking strategies, or a…

This study is conducted to further understand the direct and indirect contributions of executive functioning (visuospatial updating, verbal updating, inhibition, shifting) and arithmetic fluency to mathematical problem-solving in 458 fourth-grade students. Arithmetic fluency along with visuospatial and verbal updating were significant predictors…

Visuospatial processing speed underlies several cognitive functions critical for successful completion of everyday tasks, including driving and walking. While it is widely accepted that visuospatial processing speed peaks in early adulthood, performance across the lifespan remains incompletely characterized. Additionally, there remains a lack of…

Traumatic brain injury (TBI) may result in a wide array of cognitive deficits, including executive functions. A proposal by Ferretti and colleagues (2011 & 2013) has suggested that executive dysfunction caused by traumatic brain injury (TBI) impact navigation and discourse abilities in similar ways, suggesting that these skills may share…

Purpose: Compared to children with typical development, children with dyslexia, developmental language disorder (DLD), or both often demonstrate working memory deficits. It is unclear how pervasive the deficits are or whether the deficits align with diagnostic category. The purpose of this study was to determine whether different working memory…

We explored the potential of a robotics application in education as a measurement tool of child executive functioning skills. Sixty-five kindergarteners received assignments to go through a maze with a programmable robot, the Bee-Bot. Via observation we quantified how they solved these tasks. Their performance was successfully aggregated into a…

Technology is ubiquitous and takes many forms. Digital media consumption (e.g., television, video games, etc.) has increased significantly in its prevalence in our lives as well as in social acceptability. However, it has also been consistently implicated in poorer health outcomes. The extent to which cognitive functions are adversely affected by…

Executive function (EF) describes a complex set of skills, including flexible attention, inhibitory control, and working memory, that coordinate to achieve behavioral regulation. Visuospatial skills (VS) describe the capacity to visually perceive and understand spatial relationships among objects. Emerging research suggests VS skills are…

The current study investigated the cognitive deficit profiles among individuals with mathematics difficulties (MD) and potential moderators and mechanism for these profiles. Seventy-five cognitive profiling studies on MD were included, representing a total of 13,001 individuals and 126 independent samples. Results showed that compared with…

Clinical Question: Are people with sleep disorders at higher risk for language learning deficits than healthy sleepers? Method: Scoping Review. Study Sources: PubMed, Google Scholar, Trip Database, ClinicalTrials.gov. Search Terms: sleep disorders AND language AND learning; sleep disorders language learning--deprivation--epilepsy; sleep disorders…

Here we apply a method for automated segmentation of the hippocampus in 3D high-resolution structural brain MRI scans. One hundred and four healthy young adults completed twenty one tasks measuring abstract, verbal, and spatial intelligence, along with working memory, executive control, attention, and processing speed. After permutation tests…

Longitudinal associations of domain-general and numerical competencies with individual differences in children's understanding of fractions were investigated. Children (n = 163) were assessed at 6 years of age on domain-general (nonverbal reasoning, language, attentive behavior, executive control, visual-spatial memory) and numerical (number…

The current study focuses on the relationship between alerting and executive attention. Previous studies reported an increased flanker congruency effect following alerting cues. In the first two experiments, we found that the alertness-congruency interaction did not exist for all executive tasks (it appeared for a flanker task but not for a Stroop…
