Fluency and Reading Comprehension in Typical Readers and Dyslexics Readers

Reading involves decoding and comprehension components and, to become efficient, it requires a large number of cognitive and linguistic processes. Among those, the phonological awareness, the alphabetic principle, the decoding, the fluency, the lexical development and the text comprehension development. The reading comprehension is strongly related with the development of vocabulary, oral language, linguistic skills, memory skills and ability to make inferences, and the world experiences of each individual. These processes become important only when the professional needs to deal with students presenting difficulties in learning how to read. The difficulty using the knowledge of conversion rules between grapheme and phoneme to the word reading construction characterizes the dyslexia, which is a specific learning disorder with a neurological source. These difficulties presented by students with dyslexia interfere in their learning process impairing the learning development. Knowing and following the reading development and its processes, as well as obtaining the punctuation of fluency abilities and students comprehension allow us to understand what happens when the student presents difficulties to read. This could help in the identification of learning disabilities and in the development of intervention programs

Caracterização do Perfil Cognitivo-Linguístico de Escolares com Dificuldades de Leitura e Escrita

Investigou-se o perfil cognitivo-linguístico de escolares com dificuldades na aquisição da linguagem escrita acrescentando-se testes específicos em um modelo de resposta à intervenção (identificação e intervenção precoces do risco para transtorno de leitura). Participaram 45 escolares do 2º ano, idade média de 7 anos de ambos os gêneros, divididos em grupo controle (sem dificuldades, n = 32) e grupo de risco (com dificuldades, n = 13). Escores mais de 1,65 DP abaixo da média do grupo controle para cada teste foram considerados déficits específicos. Enquanto a análise de grupo apontou os prejuízos fonológicos como único fator de risco, a individual acrescentou a inatenção e a nomeação rápida como fatores causais independentes. Um modelo ampliado de resposta à intervenção que inclui a avaliação cognitiva é proposto.The cognitive-linguistic profile of students with reading difficulties was investigated by adding specific tests to a response to intervention model (early identification and intervention for reading disorders). Forty-five second graders of both sexes and mean age of 7 years were divided into control group (without reading difficulties, n = 32) and at-risk group (with reading difficulties, n = 13). Scores below the mean of the control group (SD > 1.65) for each test were considered as specific deficits. Whereas group analysis showed phonological impairments as the only risk factor, an individual analysis added inattention and rapid naming as independent causal factors. An extended response model to the intervention, which includes cognitive assessment, is proposed

Collective screening tools for early identification of dyslexia

Current response to intervention models (RTIs) favor a three-tier system. In general, Tier 1 consists of evidence-based, effective reading instruction in the classroom and universal screening of all students at the beginning of the grade level to identify children for early intervention. Non-responders to Tier 1 receive small-group tutoring in Tier 2. Nonresponders to Tier 2 are given still more intensive, individual intervention in Tier 3. Limited time, personnel and financial resources derail RTI's implementation in Brazilian schools because this approach involves procedures that require extra time and extra personnel in all three tiers, including screening tools which normally consist of tasks administered individually. We explored the accuracy of collectively and easily administered screening tools for the early identification of second graders at risk for dyslexia in a two-stage screening model. A first-stage universal screening based on collectively administered curriculum-based measurements was used in 45 7 years old early Portuguese readers from 4 second-grade classrooms at the beginning of the school year and identified an at-risk group of 13 academic low-achievers. Collectively administered tasks based on phonological judgments by matching figures and figures to spoken words [alternative tools for educators (ATE)] and a comprehensive cognitive-linguistic battery of collective and individual assessments were both administered to all children and constituted the second-stage screening. Low-achievement on ATE tasks and on collectively administered writing tasks (scores at the 25th percentile) showed good sensitivity (true positives) and specificity (true negatives) to poor literacy status defined as scores <= 1 SD below the mean on literacy abilities at the end of fifth grade. These results provide implications for the use of a collectively administered screening tool for the early identification of children at risk for dyslexia in a classroom setting

Motor skills assessments: support for a general motor factor for the Movement Assessment Battery for Children-2 and the Bruininks-Oseretsky Test of Motor Proficiency-2

Abstract Objective To evaluate the construct validity and model-based reliability of general and specific contributions of the subscales of the Movement Assessment Battery for Children-2 (MABC-2) and Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) when evaluating motor skills across a range of psychiatric disorders. Methods Confirmatory factor analysis (CFA) and bifactor analysis were conducted on BOT-2 data from 187 elementary school students (grades 1 to 6) (mean age: 113 ± 20 months; boys: n = 117, 62.56%) and on MABC-2 data from 127 elementary school students (grade 1) (mean age: 76 ± 2 months; boys: n = 58, 45.67%). Results The results of the CFA fit the data for multidimensionality for the BOT-2 and presented poor fit indices for the MABC-2. For both tests, the bifactor model showed that the reliability of the subscales was poor. Conclusions The BOT-2 exhibited factorial validity with a multidimensional structure among the current samples, but the MABC-2 showed poor fit indices, insufficient to confirm its multidimensional structure. For both tests, most of the reliable variance came from a general motor factor (M-factor), therefore the scoring and reporting of subscale scores were not justified for both tests

Assessment and comparison of auditory and cognitive-linguistic skills in school-age children

O desenvolvimento dos sistemas auditivo e cognitivo-linguístico ocorrem em simultâneo, assumindo um papel importante na aprendizagem. Surge, assim, a necessidade de investigação dos dois sistemas, através de um estudo quantitativo, com o objetivo de identificar as respostas auditivas e cognitivo-linguísticas mais relacionadas. 150 crianças serão sujeitas à avaliação cognitivo-linguística e 10 à avaliação do Processamento Auditivo. Os pais/professores das 150 crianças preencherão, também, o questionário auditivo para recolha de informações. A análise dos dados dessa avaliação contribuirá para a realização de diagnósticos mais precisos e para a delineação de estratégias de intervenção mais adequadas.The development of the auditory and cognitive-linguistic systems occur simultaneously, assuming an important role in learning. Thus, there is a need to investigate the two systems through a quantitative study, with the objective of identifying the most closely related auditory and cognitive-linguistic responses. 150 children will be subject to cognitive-linguistic evaluation and 10 to Auditory Processing evaluation. The parents/teachers of the 150 children will also fill in the auditory questionnaire to collect information. The analysis of the data of this evaluation will contribute to the accomplishment of more accurate diagnoses and to the delineation of more adequate intervention strategies.CIEC - Centro de Investigação em Estudos da Criança, IE, UMinho (UI 317 da FCT), PortugalFundos Nacionais através da FCT (Fundação para a Ciência e a Tecnologia) e cofinanciado pelo Fundo Europeu de Desenvolvimento Regional (FEDER) através do COMPETE 2020 – Programa Operacional Competitividade e Internacionalização (POCI) com a referência POCI-01-0145-FEDER-007562info:eu-repo/semantics/publishedVersio
