Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest relation stems from inhibitory control demands incongruent visual cues nonsymbolic number comparison task. This study investigated among during differing congruency conditions, executive function, and achievement measured longitudinally children (n = 448) ages 4 to 13. was across groups as it related full range of achievement. Only performance...
Abstract Research indicates that the neurocognitive system representing nonsymbolic numerical magnitudes is foundational for development of mathematical competence. However, recent studies found most common task used to measure acuity, number comparison task, heavily influenced by non‐numerical visual parameters stimuli increase executive function demands. Further, this influence may be a confound invalidating theoretical accounts relation between performance and Instead depend on one's...
The present study investigates the relation between resting-state functional connectivity (rsFC) of cytoarchitectonically defined subdivisions parietal cortex at end 1st grade and arithmetic performance 2nd grade. Results revealed a dissociable pattern relations rsFC competence among intraparietal sulcus (IPS) angular gyrus (AG). right hemisphere IPS contralateral positively correlated with competence. In contrast, left hIP1 medial temporal lobe, AG superior frontal gyrus, were negatively...
Abstract Attention and executive functions (EFs) play a critical role in academic skill development, including literacy numeracy. Deficits attention EFs often accompany learning disorders, such as dyslexia dyscalculia. Despite their well‐established link, we lack nuanced understanding of the specific neurobiological mechanisms that integrate higher order cognitive processes (e.g., control) with control lower‐level cognition related to domain‐specific skills processing numerical information)....
Math performance is negatively related to math anxiety (MA), though MA may impact certain skills more than others. We investigated whether the relation between and affected by task features, such as number type (e.g., fractions, whole numbers, percentages), format (symbolic vs. nonsymbolic), ratio component size (small large). Across two large-scale studies (combined
Motion remains a significant technical hurdle in fMRI studies of young children. Our aim was to develop straightforward and effective method for obtaining preprocessing resting state data from high-motion pediatric cohort. This approach combines real-time monitoring head motion with pipeline that uses volume censoring concatenation alongside independent component analysis based denoising. We evaluated this using sample 108 first grade children (age 6-8) enrolled longitudinal study math...
Abstract Functional neuroimaging serves as a tool to better understand the cerebral correlates of atypical behaviors, such learning difficulties. While significant advances have been made in characterizing neural reading difficulties (developmental dyslexia), comparatively little is known about neurobiological mathematical difficulties, developmental dyscalculia (DD). Furthermore, available studies DD are characterized by small sample sizes and variable inclusion criteria, which make it...
Magnitude processing and executive functions (EFs) have emerged as robust predictors of mathematics achievement. However, the nature these associations is still unclear. For example, it uncertain if EFs applied in context domain-specific mathematical cognition (i.e., while numbers) are more closely related to achievement than nonnumerical, domain-general contexts. Also, how distinct EF domains-that is, working memory, inhibitory control, cognitive flexibility-and contents-that numerical...
Debate continues on whether encoding of symbolic number is grounded in nonsymbolic numerical magnitudes. Nevertheless, fluency perceiving both formats, and translating between them, predicts math skills across the life span. Therefore, this study asked if numbers share cortical activation patterns formats tasks, neural response to math-related behaviors. We analyzed using 7 Tesla functional magnetic resonance imaging a sample 39 healthy adults. Discrimination was successful numerosities 2,...
Abstract The development of math skills is a critical component early education and strong indicator later school economic success. Recent research utilizing population‐normed, standardized measures achievement suggest that structural functional integrity parietal regions, especially the intraparietal sulcus, are closely related to skills. However, it unknown how these findings relate in‐school learning. present study first address this issue by investigating relationship between regional...
Abstract A critical goal of cognitive neuroscience is to predict behavior from neural structure and function, thereby providing crucial insights into who might benefit clinical and/or educational interventions. Across development, the strength functional connectivity among a distributed set brain regions associated with children’s math skills. Therefore, in present study we use connectome-based predictive modeling investigate whether during numerical processing at rest “predicts” skills (N =...
During the COVID-19 pandemic, people across globe have been exposed to large amounts of statistical data. Previous studies shown that individuals' mathematical understanding health-related information affects their attitudes and behaviours. Here, we investigate relation between (i) basic numeracy, (ii) health (iii) An online survey measuring these three variables was distributed in Canada, United States (US) Kingdom (UK) (n = 2032). In line with predictions, numeracy positively related...
Children's ability to discriminate nonsymbolic number (e.g., the of items in a set) is commonly studied predictor later math skills. Number discrimination improves throughout development, but what drives this improvement unclear. Competing theories suggest that it may be due sharpening numerical representation or an improved pay attention and filter out non-numerical information. We investigate issue by studying change children's performance (N = 65) on comparison task, where children decide...
Studies of brain activity during number processing suggest symbolic and nonsymbolic numerical stimuli (e.g., Arabic digits dot arrays) engage both shared distinct neural mechanisms. However, the extent to which format influences large-scale functional network organization is unknown. In this study, using 7 Tesla MRI, we adopted a neuroscience approach characterize whole-brain architecture supporting comparison in 33 adults. Results showed degree global modularity was similar for formats. The...
