“…Furthermore, obtaining a better understanding of child AERPs might also prove beneficial to the study of these components in children with developmental disorders such as dyslexia. Children with dyslexia are characterized by language related deficits, such as very poor reading and spelling skills, and evidence exists for atypical AERPs in this population (Hämäläinen et al, 2007;Leppänen and Lyytinen, 1997;Lyytinen et al, 2005;van Herten et al, 2008).…”

“…This may enable them to develop typical reading skills that might be otherwise compromised due to atypical/alternative brain development associated with a familial risk of dyslexia. As a group, infants and children with a familial risk of dyslexia seem to show a greater predisposition for a bilateral/right‐lateralized brain network supporting language and reading development, compared to controls who show a primarily left‐hemispheric dominance (e.g., Guttorm et al, ; Leppänen et al, ; Lyytinen et al, ; van Herten et al, ; van Leeuwen et al, ; van Leeuwen et al, ; Wang et al, ; for reviews, also see Lyytinen et al, and Ozernov‐Palchik & Gaab, ). For example, enhanced neural sensitivity to speech sounds in the right hemisphere has been observed in FHD+ compared to FHD− infants within the first couple days of life (Guttorm et al, ).…”

Developmental dyslexia affects 40–60% of children with a familial risk (FHD+) compared to a general prevalence of 5–10%. Despite the increased risk, about half of FHD+ children develop typical reading abilities (FHD+Typical). Yet the underlying neural characteristics of favorable reading outcomes in at‐risk children remain unknown. Utilizing a retrospective, longitudinal approach, this study examined whether putative protective neural mechanisms can be observed in FHD+Typical at the prereading stage. Functional and structural brain characteristics were examined in 47 FHD+ prereaders who subsequently developed typical (n = 35) or impaired (n = 12) reading abilities and 34 controls (FHD−Typical). Searchlight‐based multivariate pattern analyses identified distinct activation patterns during phonological processing between FHD+Typical and FHD−Typical in right inferior frontal gyrus (RIFG) and left temporo‐parietal cortex (LTPC) regions. Follow‐up analyses on group‐specific classification patterns demonstrated LTPC hypoactivation in FHD+Typical compared to FHD−Typical, suggesting this neural characteristic as an FHD+ phenotype. In contrast, RIFG showed hyperactivation in FHD+Typical than FHD−Typical, and its activation pattern was positively correlated with subsequent reading abilities in FHD+ but not controls (FHD−Typical). RIFG hyperactivation in FHD+Typical was further associated with increased interhemispheric functional and structural connectivity. These results suggest that some protective neural mechanisms are already established in FHD+Typical prereaders supporting their typical reading development.

“…2) revealed two time-windows in which the matching and unrelated conditions distinctly differed: An early P2, and a late N400 time-window. To test for potential group differences in these time-windows, we analysed mean amplitudes in the P2 time-window (170-300 ms; see Van Herten et al (2008) for similar P2 latencies in slightly younger children) and the N400 time window (350-550 ms; Kutas & Federmeier, 2011). Although our P2 window clearly falls outside the P1 time-window (Fig.…”

Bilingualism and increased attention to speech: Evidence from event-related potentials

A number of studies have shown that from an early age, bilinguals outperform their monolingual peers on executive control tasks. We previously found that bilingual children and adults also display greater attention to unexpected language switches within speech. Here, we investigated the effect of a bilingual upbringing on speech perception in one language. We recorded monolingual and bilingual toddlers' event-related potentials (ERPs) to spoken words preceded by pictures. Words matching the picture prime elicited an early frontal positivity in bilingual participants only, whereas later ERP amplitudes associated with semantic processing did not differ between groups. These results add to the growing body of evidence that bilingualism increases overall attention during speech perception whilst semantic integration is unaffected.
