Efeitos do ensino remoto de emparelhamento auditivo-visual com letras na nomeação de letras em crianças com Síndrome de Down e Autismo / Effects of remote teaching of auditory-visual matching with letters on letter naming in children with Down Syndrome and Autism / Efectos de enseñar a distancia del emparejamiento auditivo-visual com letras para nombrar las letras em niños con Síndrome de Down y Autismo

Este artigo realizou uma replicação sistemática do estudo de Hayashi et al. (2013) e teve como objetivo ava-liar a emergência de nomeação de letras a partir do ensino de emparelhamento auditivo-visual, no contexto do ensino remoto, diante da pandemia de Covid-19. Participaram da pesquisa quatro alunos, de ambos os gêneros, com idades entre 5 e 10 anos, três deles com síndrome de Down e uma participante com Transtorno do Espectro Autista. A coleta de dados realizou-se por meio da plataforma Zoom, individualmente, e utilizou um software específico para programação e registro das respostas. O ensino constituiu na seleção da letra maiúscula impressa, apresentada na tela do computador simultaneamente com as demais letras impressas do conjunto, diante do nome da letra ditado. Na avaliação, a criança deveria nomear a letra. Foi empregado um delineamento de múltiplas sondagens entre conjuntos de letras. Os resultados mostraram que os quatros participantes apresentaram aumento da nomeação correta das letras após as sessões de ensino para a maio-ria dos conjuntos. Os dados indicaram que o procedimento de ensino pode ser uma alternativa viável para estabelecer o reconhecimento e nomeação de letras com pessoas público-alvo da educação especial, suple-mentando o ensino da escola regular e podendo ser conduzido por professores e familiares

This study aimed to replicate the study of Hayashi et al. (2013) and to assess the emergence of letter naming from the teaching of auditory-visual pairing, in the context of remote teaching, in view of the Covid-19 pandemic. Four students, of both genders, aged five to ten years, three of them with Down syndrome and one participant with Autistic Spectrum Disorder participated in the research. Data collection was performed using the Zoom platform, individually. Teaching consisted of the selection of the printed capital letter, presented on the computer screen simultaneously the printed letters of the set, and the letter name dictated. In the evaluation, the child named the letter. A design of multiple probes between sets of letters was used. The results showed that all four participants showed an increase in correct letter naming after the teaching sessions for most letter sets. The data indicated that the teaching procedure can be a viable alternative to establish the recognition and naming of letters with people who are the target audience of Special Education, supplementing regular school teaching and can be conducted by teachers and family members

Esta investigación tuvo como objetivo replicar el estudio de Hayashi et al. (2013) y evaluar el surgimiento de la denominación de letras desde la enseñanza del binomio auditivo-visual, en el contexto de la enseñanza remota, frente a la pandemia del Covid-19. Participaron en la investigación cuatro estudiantes, de ambos sexos, con edades entre 5 y 10 años, tres de ellos con síndrome de Down y uno con Trastorno del Espectro Autista. La colecta de datos se realizó a través de la plataforma Zoom, de forma individual. El proceso de enseñanza consistió en la selección de la letra mayúscula impresa presentada en la pantalla de la compu-tadora simultáneamente a las letras impresas del conjunto frente al nombre de la letra dictada. En la eva-luación, el niño nombró la letra. Se utilizó un diseño de sonorización múltiple entre conjuntos de letras. Los resultados mostraron que los cuatro participantes tuvieron un aumento en la denominación correcta de las letras después de las sesiones de enseñanza para la mayoría de los conjuntos de letras. Los datos indicaron que el procedimiento de enseñanza puede ser una alternativa viable para las personas que requieren de educación especial al establecer el reconocimiento y el nombramiento de las letras, este método puede ser un suplemento de la escolarización y puede llevarse a cabo por profesores y familiares.

Evidence for cross-script abstract identities in learners of Japanese kana.

The presence of abstract letter identity representations in the Roman alphabet has been well documented. These representations are invariant to letter case (upper vs. lower) and visual appearance. For example, "a" and "A" are represented by the same abstract identity. Recent research has begun to consider whether the processing of non-Roman orthographies also involves abstract orthographic representations. In the present study, we sought evidence for abstract identities in Japanese kana, which consist of two scripts, hiragana and katakana. Abstract identities would be invariant to the script used as well as to the degree of visual similarity. We adapted the cross-case masked-priming letter match task used in previous research on Roman letters, by presenting cross-script kana pairs and testing adult beginning -to- intermediate Japanese second-language (L2) learners (first-language English readers). We found robust cross-script priming effects, which were equal in magnitude for visually similar (e.g., り/リ) and dissimilar (e.g., あ/ア) kana pairs. This pattern was found despite participants' imperfect explicit knowledge of the kana names, particularly for katakana. We also replicated prior findings from Roman abstract letter identities in the same participants. Ours is the first study reporting abstract kana identity priming (in adult L2 learners). Furthermore, these representations were acquired relatively early in our adult L2 learners.

Effects of letter-identification training on letter naming in prereading children.

Three prereading children who named 0 to 3 of 20 targeted letters were taught to select the 20 printed letters when they heard spoken letter names. For all participants, letter-identification training resulted in naming for the majority of letters.

How Many Letters Should Preschoolers in Public Programs Know? The Diagnostic Efficiency of Various Preschool Letter-Naming Benchmarks for Predicting First-Grade Literacy Achievement.

Review of current federal and state standards indicates little consensus or empirical justification regarding appropriate goals, often referred to as benchmarks, for preschool letter-name learning. The present study investigated the diagnostic efficiency of various letter-naming benchmarks using a longitudinal database of 371 children who attended publicly funded preschools. Children's uppercase and lowercase letter-naming abilities were assessed at the end of preschool, and their literacy achievement on 3 standardized measures was assessed at the end of 1st grade. Diagnostic indices (sensitivity, specificity, and negative and positive predictive power) were generated to examine the extent to which attainment of various preschool letter-naming benchmarks was associated with later risk for literacy difficulties. Results indicated generally high negative predictive power for benchmarks requiring children to know 10 or more letter names by the end of preschool. Balancing across all diagnostic indices, optimal benchmarks of 18 uppercase and 15 lowercase letter names were identified. These findings are discussed in terms of educational implications, limitations, and future directions.
