Preschool deficits in cardinal knowledge and executive function contribute to longer-term mathematical learning disability

Publication date: December 2019Source: Journal of Experimental Child Psychology, Volume 188Author(s): Felicia W. Chu, Kristy vanMarle, Mary K. Hoard, Lara Nugent, John E. Scofield, David C. GearyAbstractIn a preschool through first grade longitudinal study, we identified groups of children with persistently low mathematics achievement (n = 14) and children with low achievement in preschool but average achievement in first grade (n = 23). The preschool quantitative developments of these respective groups of children with mathematical learning disability (MLD) and recovered children and a group of typically achieving peers (n = 35) were contrasted, as were their intelligence, executive function, and parental education levels. The core characteristics of the children with MLD were poor executive function and delayed understanding of the cardinal value of number words throughout preschool. These compounded into even more substantive deficits in number and arithmetic at the beginning of first grade. The recovered group had poor executive function and cardinal knowledge during the first year of preschool but showed significant gains during the second year. Despite these gains and average mathematics achievement, the recovered children had subtle deficits with accessing magnitudes associated with numerals and addition combinations (e.g., 5 + 6 = ?) in first grade. The study provides unique insight into domain-general and quantitative deficits in preschool that increa...

Findings from recent studies using Item Response Theory methods advance the idea that some aspects of the MSWS-12 does not fully comply with some requirements of sound measurement.Research questionThe present study investigated whether the measurement prope...

ConclusionsThis study is the first to investigate possible lncRNA biomarkers to differentiate phenotypic severity in MS. Although the findings are preliminary based on our small sample size, they are sufficient to identify hypotheses for future investigation, and give guidance regarding the design of future studies.

Conclusions: Many patients with rheumatic conditions (especially fibromyalgia) face long delays before receiving services in Quebec's MPTF. This study identified several factors associated with waiting time and emphasizes the need to improve access to pain management services. PMID: 31534361 [PubMed]

Discussion: The MP is a promising tool for increasing patient mobility in the nonintensive care GM and GS setting, while potentially decreasing the need for PAC rehabilitation for many patients with minimal mobility deficits. Although not all of the results were statistically significant, positive effects on hospital ratings show promise toward helping to improve the overall patient experience during admission, decreasing LOS, decreasing overall fall rate, and an associated decrease in GM patient PAC spending in those most likely to be affected by HAD related to immobility. These positive effects can potentially improve ...

CONCLUSION: Different forms of discrimination are associated with PEs in the general population. As discrimination is common at the societal level, this highlights the importance of public policy and evidence-based interventions to reduce discrimination and improve population mental health.

CONCLUSION: There is convincing evidence to demonstrate a causal relationship between bullying victimisation and mental disorders. This study showed that bullying victimisation contributes a significant proportion of the burden of anxiety and depressive disorders. The investment and implementation of evidence-based intervention programmes that reduce bullying victimisation in schools could reduce the burden of disease arising from common mental disorders and improve the health of Australians.

Abstract From the time it was conceptualized in 1998 to the present, RNAS+ has largely concentrated on research that will generate results to facilitate control, prevention and elimination of its target diseases. Diagnostics has remained an active field of research in order to develop tools that are appropriate for each stage from the first efforts until attempts to block transmission. For example, with regard to schistosomiasis, chemotherapy has excellent impact on morbidity, while better diagnostics and vaccine research have been promoted to complement the other components of the control programme. The need for ...
