ABSTRACT. Brazilian students’ mathematical achievement was repeatedly observed to fall below average levels of mathematical attainment in international studies such as PISA. Objective: In this article, we argue that this general low level of mathematical attainment may interfere with the diagnosis of developmental dyscalculia when a psychometric criterion is used establishing an arbitrary cut-off (e.g., perform...
ABSTRACT Math anxiety (MA) is a feeling of dread, tension and anxiety when dealing with math situations. Avoidance behavior prevents children from learning math, impairing their performance. Cognitive behavioral therapy is an approach with robust evidence of efficacy in treating anxiety disorders. The Coping Cat, a protocol for treating anxiety disorders, inspired the MA intervention reported here. The particip...
ABSTRACT It is still debated if the main deficit in mathematical difficulties (MD) is nonsymbolic or symbolic numerical magnitude processing. Objectives: In the present study, our main goal was to investigate nonsymbolic and symbolic numerical magnitude processing in MD and the relationship between these abilities and arithmetic. Methods: The Brazilian school-age children with MD completed a nonsymbolic and a s...
ABSTRACT Introduction: Reading disability (RD) and Attention Deficit Hyperactivity Disorder (ADHD) symptoms often co-occur in school-age children. Methods: The present study evaluated the performance of 216 Brazilian children from 3rd and 4th grades on “cool” executive function (EF) abilities and phonological processing. The children were divided into three groups: those with ADHD symptoms only, those with RD o...
Abstract Introduction Rapid automatized naming (RAN) is the ability to name, as fast as possible, symbols such as letters, digits and figures. The present study aimed to investigate intragroup performance patterns on RAN tasks in children with attention deficit hyperactivity disorder (ADHD) symptoms alone, children with reading disability (RD) alone and controls with typical development. Methods A total of 216 ...
ABSTRACT The Mini-Mental Examination for Children (MMC) is a widely used tool for assessing global cognitive deficits, however,is still unknown whether MMC is sensitive for investigating cognitive profiles associated with learning difficulties (LD). Objective: Here we investigate the feasibility of using the MMC for screening school-aged children with learning difficulties in spelling and math. Methods: The MMC...
Abstract Math learning disability (MLD) is a heterogeneous condition characterized by severe and persistent difficulties in learning math, including difficulties in learning multiplication facts. Objective: In this article, we compared the responses of two MLD children to multiplication facts training. Methods: One of the children was a 9 year-old girl (HV) who presented mild math difficulties associated with l...
ABSTRACT In many countries, a radical political divide brings several socially relevant decisions to a standstill. Could cognitive, affective and social (CAS) neuroscience help better understand these questions? The present article reviews the moral-psychological and neuroevolutionary basis of the political partisanship divide. A non-systematic literature review and a conceptual analysis were conducted. Three m...
ABSTRACT Cognitive impairment is frequent in cerebral palsy (CP) and there is a lack of multiprofessional screening instruments. OBJECTIVE: The aim of this study was to investigate the utility of the Mini-Mental State Examination for Children (MMC), an adapted version of the Mini-Mental State Examination, in screening for cognitive impairments in children with CP. METHODS: We assessed 397 Brazilian children, 31...
Clinical observations indicate that many children with hemiplegic cerebral palsy (HCP) exhibit a lack of use or disregard of the affected upper limb. The aim of the present study was to develop, adapt, and verify the psychometric properties of a neuropsychological battery to assess body perception and representation disturbances in children with HCP. Three groups of children participated in this study, who took...
