Soares, Lages, Oliveira, and Cabrera-Hernández (2019) recently showed that the mirror-letter interference effect observed for words containing reversal letters was reliable for words containing left-oriented mirror-letters as 'd', but not for words containing right-oriented mirror-letters as 'b', thus indicating that the directionality of the…

It is widely accepted that orthographic knowledge comprises two components: word-specific orthographic knowledge, also termed lexical orthographic knowledge, and general orthographic knowledge, or sublexical orthographic knowledge. Until now, the study of the relationship between these components throughout literacy development has been somehow…

We examined the contribution of a major predictor of basic literacy ability--phoneme awareness--to individual differences in two arithmetic computation tasks: a speeded task consisting of simple computation problems (arithmetic fluency) and an untimed, more complex computation task involving multi-digit operands (numerical operations). The…

This study investigates spelling abilities of 189 second, third, and fourth graders using a word and pseudoword dictation task in European Portuguese. We analyzed the effect of orthographic complexity on spelling accuracy and the moderating role of length (two vs. three syllables), lexicality (words vs. pseudowords), and grade (second, third, and…

The role of syllables as a sublexical unit in visual word recognition and reading is well established in deep and shallow syllable-timed languages such as French and Spanish, respectively. However, its role in intermediate stress-timed languages remains unclear. This paper aims to overcome this gap by studying for the first time the role of…

This study investigated direct and indirect effects between oral reading fluency, vocabulary and reading comprehension across reading development in European Portuguese. Participants were 329 children attending basic education, from grade 1 to grade 6. The results of path analyses showed that text reading fluency is much more dependent on the…

Empirical research has provided evidence for the simple view of reading across a variety of orthographies, but the role of oral reading fluency in the model is unclear. Moreover, the relative weight of listening comprehension, oral reading fluency and word recognition in reading comprehension seems to vary across orthographies and schooling years.…

This study analyzed the relation and the specific influence of rapid naming (RN) on different reading (decoding accuracy and reading fluency) and writing components (spelling accuracy and fluency in composition) of European Portuguese. Moreover, it also compares the influence of Rapid Automatized Naming (RAN) tests (colors, digits) and of a Rapid…

Two studies were conducted to investigate the correlates of hyperlexia in Brazilian Portuguese-speaking children with the diagnosis of autism spectrum disorder (ASD). Study 1 involved 3 groups of school age children individually matched for word reading ability: 6 ASD hyperlexic children, 6 ASD non-hyperlexic children, and 6 typically developing…

Fifteen Portuguese children with dyslexia, aged 9-11 years, were compared with reading and chronological age controls with respect to five indicators related to the phonological deficit hypothesis: the effects of lexicality, regularity, and length, implicit and explicit phonological awareness, and rapid naming. The comparison between groups…

An important element of learning to read and write at school is the ability to define word boundaries. Defining word boundaries in text writing is not a straightforward task even for children who have mastered graphophonemic correspondences. In children's writing, unconventional word segmentation has been observed across a range of languages and…

Examines the nature of language, memory, and reading skills of bilingual Portuguese-Canadian students and determines the relationship between reading problems in English and reading problems in Portuguese. Finds that the majority (67%) showed at least an average proficiency in both languages. Suggests that bilingualism does not have negative…

Investigates whether Brazilian Portuguese-speaking prereaders who have mastered letter names are capable of processing letter-sound relations to learn to read words in which the letters correspond to phonemes contained in the names of the letters. Suggests they can use their knowledge of the names of the letters to learn to read by processing and…

Examines whether letter-name knowledge facilitates learning spellings in which the names of one or more letters can be heard in the pronunciation of the words. Results suggest preschool Portuguese children who know the names of the letters can learn to read by processing letter-sound relations in words; however, children may not use this mechanism…
