“…In particular, visual spatial attentional deficits captured by our labyrinth task highlight that both distributed and focused spatial attention could be impaired in children with RD. These visual attentional mechanisms are fundamental for both lexical and sublexical reading pathways development 12 , 71 , 81 , 82 .…”

Although developmental reading disorders (developmental dyslexia) have been mainly associated with auditory-phonological deficits, recent longitudinal and training studies have shown a possible causal role of visuo-attentional skills in reading acquisition. Indeed, visuo-attentional mechanisms could be involved in the orthographic processing of the letter string and the graphemic parsing that precede the grapheme-to-phoneme mapping. Here, we used a simple paper-and-pencil task composed of three labyrinths to measure visuo-spatial attention in a large sample of primary school children (n = 398). In comparison to visual search tasks requiring visual working memory, our labyrinth task mainly measures distributed and focused visuo-spatial attention, also controlling for sensorimotor learning. Compared to typical readers (n = 340), children with reading difficulties (n = 58) showed clear visuo-spatial attention impairments that appear not linked to motor coordination and procedural learning skills implicated in this paper and pencil task. Since visual attention is dysfunctional in about 40% of the children with reading difficulties, an efficient reading remediation program should integrate both auditory-phonological and visuo-attentional interventions.

“…Franceschini et al, 2013 ; Lallier et al, 2014 ). Evidence for the relationship between global–local attention and phonological and lexical processing has been previously offered by Franceschini et al ( 2021 ), who used the global–local task to bias the grain of attention and explore the influence of lexical and phonological processing within language. Our study is the first extension of the dynamic interaction between language and attention across languages in a writing production task for monolingual and bilingual participants.…”

“…Recently, it has been proposed that the local task has a connection with lexical and sublexical processing strategies during reading. Franceschini et al ( 2021 ) administered consecutive local trials to induce a ‘local mode’ of processing and consecutive global trials to induce a ‘global mode’. Their results showed that after the induction of a local mode, reading irregular words (which required lexical processing) was significantly slower than reading regular words (which required phonological processing).…”

“…Mottron et al, 2003 ; Yovel et al, 2005 ; see Goldstein‐Marcusohn et al, 2020 ). Second, regarding the transfer between language and attention, local attention has been shown to have a differential effect on lexical vs. phonological processing, whereas global induction did not have any differential effect on lexical and phonological processing strategies (Franceschini et al, 2021 ).…”

The consistency between letters and sounds varies across languages. These differences have been proposed to be associated with different reading mechanisms (lexical vs. phonological), processing grain sizes (coarse vs. fine) and attentional windows (whole words vs. individual letters). This study aimed to extend this idea to writing to dictation. For that purpose, we evaluated whether the use of different types of processing has a differential impact on local windowing attention: phonological (local) processing in a transparent language (Spanish) and lexical (global) processing of an opaque language (English). Spanish and English monolinguals (Experiment 1) and Spanish-English bilinguals (Experiment 2) performed a writing to dictation task followed by a global-local task. The first key performance showed a critical dissociation between languages: the response times (RTs) from the Spanish writing to dictation task was modulated by word length, whereas the RTs from the English writing to dictation task was modulated by word frequency and age of acquisition, as evidence that language transparency biases processing towards phonological or lexical strategies. In addition, after a Spanish task, participants more efficiently processed local information, which resulted in both the benefit of global congruent information and the reduced cost of incongruent global information. Additionally, the results showed that bilinguals adapt their attentional processing depending on the orthographic transparency.

“…The consequence of the resulting relative local precedence is that reading cannot rely on the initial classification of letter strings that normally precedes identification of individual elements (cf. [143]).…”

The Brain’s Asymmetric Frequency Tuning: Asymmetric Behavior Originates from Asymmetric Perception

et al. 2020

To construct a coherent multi-modal percept, vertebrate brains extract low-level features (such as spatial and temporal frequencies) from incoming sensory signals. However, because frequency processing is lateralized with the right hemisphere favouring low frequencies while the left favours higher frequencies, this introduces asymmetries between the hemispheres. Here, we describe how this lateralization shapes the development of several cognitive domains, ranging from visuo-spatial and numerical cognition to language, social cognition, and even aesthetic appreciation, and leads to the emergence of asymmetries in behaviour. We discuss the neuropsychological and educational implications of these emergent asymmetries and suggest future research approaches.
