Brain responses to changes in speech sound durations differ between infants with and without familial risk for dyslexia

PHT Leppänen, U Richardson, E Pihko… - Developmental …, 2002 - Taylor & Francis
A specific learning disability, developmental dyslexia, is a language-based disorder that is
shown to be strongly familial. Therefore, infants born to families with a history of the disorder …

Speech perception of infants with high familial risk for dyslexia differ at the age of 6 months

U Richardson, PHT Leppänen, M Leiwo… - Developmental …, 2003 - Taylor & Francis
As yet relatively little is known of the earliest signs of dyslexia. We present evidence showing
that the speech perception of 6-month-old infants from dyslexic families differs significantly …

Newborn brain event-related potentials revealing atypical processing of sound frequency and the subsequent association with later literacy skills in children with …

PHT Leppänen, JA Hämäläinen, HK Salminen… - Cortex, 2010 - Elsevier
The role played by an auditory-processing deficit in dyslexia has been debated for several
decades. In a longitudinal study using brain event-related potentials (ERPs) we investigated …

An extensive pattern of atypical neural speech-sound discrimination in newborns at risk of dyslexia

A Thiede, P Virtala, I Ala-Kurikka, E Partanen… - Clinical …, 2019 - Elsevier
Objective Identifying early signs of developmental dyslexia, associated with deficient speech-
sound processing, is paramount to establish early interventions. We aimed to find early …

Event-related potentials and consonant differentiation in newborns with familial risk for dyslexia

TK Guttorm, PHT Leppänen… - Journal of Learning …, 2001 - journals.sagepub.com
We measured event-related potentials (ERPs) to synthetic consonant-vowel syllables
(/ba/,/da/,/ga/) from 26 newborns with familial risk for dyslexia and 23 control infants …

Auditory processing, speech perception and phonological ability in pre-school children at high-risk for dyslexia: A longitudinal study of the auditory temporal …

B Boets, J Wouters, A Van Wieringen, P Ghesquiere - Neuropsychologia, 2007 - Elsevier
This study investigates whether the core bottleneck of literacy-impairment should be situated
at the phonological level or at a more basic sensory level, as postulated by supporters of the …

Speech perception in preschoolers at family risk for dyslexia: Relations with low-level auditory processing and phonological ability

B Boets, P Ghesquière, A van Wieringen, J Wouters - Brain and language, 2007 - Elsevier
We tested categorical perception and speech-in-noise perception in a group of five-year-old
preschool children genetically at risk for dyslexia, compared to a group of well-matched …

Cortical responses of infants with and without a genetic risk for dyslexia: II. Group effects

PHT Leppänen, E Pihko, KM Eklund, H Lyytinen - Neuroreport, 1999 - journals.lww.com
INFANTS born to families with a background of developmental dyslexia have an increased

Mismatch response is absent in 2-month-old infants at risk for dyslexia

T van Leeuwen, P Been, C Kuijpers, F Zwarts… - …, 2006 - journals.lww.com
This study examined auditory processing in 2-month-old infants at genetic risk for dyslexia

A longitudinal study investigating neural processing of speech envelope modulation rates in children with (a family risk for) dyslexia

A De Vos, S Vanvooren, J Vanderauwera… - Cortex, 2017 - Elsevier
Recent evidence suggests that a fundamental deficit in the synchronization of neural
oscillations to temporal information in speech may underlie phonological processing …
