Mothers' Causal Attributions Concerning the Reading Achievement of Their Children With and Without Familial Risk for Dyslexia
2008
The present study analyzed data from the Jyväskylä Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school year. Children's verbal intelligence was assessed at 5 years and their word and nonword reading skills at 6.5 years. The results showed that the higher the word reading skills the children had, the more their mothers attributed their success to ability than to effort. However, if children had familial risk for dyslexia, their mothers' attribution o…
Communication Deviance in parents of families with adoptees at a high or low risk of schizophrenia-spectrum disorders and its associations with attri…
2009
Communication Deviance (CD) in rearing parents is a known indicator of a psychopathology risk in the offspring, but the direction of the effects of these two factors on each other has remained an unresolved question. The purpose of the present study was to clarify this issue by assessing the relationship of CD in adoptive parents with certain attributes of the adoptee and adoptive parents themselves. The subjects were 109 adoptees at a high or low risk of schizophrenia-spectrum disorders and their adoptive parents. Communication Deviance was measured in individual, spouse and family Rorschach situations. Thought disorders in the adoptees were assessed using the Thought Disorder Index. The v…
Reading for meaning in dyslexic and young children : distinct neural pathways but common endpoints
2009
Developmental dyslexia is a highly prevalent and specific disorder of reading acquisition characterised by impaired reading fluency and comprehension. We have previously identified fMRI- and ERP-based neural markers of impaired sentence reading in dyslexia that indicated both deviant basic word processing and deviant semantic incongruency processing. However, it remained unclear how specific these impairments are for dyslexia, as they occurred when children with dyslexia (DYS) were compared to chronological age-matched controls (CA) who also differ in the amount of reading experience. Adding a younger control group at a similar reading level (RL) as the dyslexic group, we examined here whic…
Left minineglect or inverse pseudoneglect in children with dyslexia?
2011
International audience; This study compared the visuospatial asymmetries in children with dyslexia and healthy children by using the manual line bisection task, and investigated the processing of spatial context with a 'local' cueing paradigm consisting of geometric symbols placed on the extremities of the lines. The performance between healthy children (leftward bias) and children with dyslexia (rightward bias) was significantly different. Furthermore, the bisection mark was shifted in the direction of the unilaterally cued extremities in all children. As children with dyslexia showed a rightward bias in their spatial representation, which did not interfere with local context processing, w…
Event-related potentials in newborns with and without familial risk for dyslexia: principal component analysis reveals differences between the groups
2003
Differences revealed by factor scores extracted by principal component analysis (PCA) from event-related potential (ERP) data of newborns with and without familial risk for dyslexia were examined and compared to results obtained by using original averaged ERPs. ERPs to consonant-vowel syllables (synthetic /ba/, /da/, /ga/; and natural /paa/, /taa/, /kaa/) were recorded from 26 at-risk and 23 control 1-7 day-old infants. The stimuli were presented equiprobably and with interstimulus intervals varying at random from 3,910 to 7,285 ms. Statistically significant between-group differences were found to be relatively similar irrespective of the methods of analysis (original ERPs vs. factor scores…
Diagnostic subgroups of developmental dyslexia have different deficits in neural processing of tones and phonemes.
2004
The present study addressed auditory processing in 8-11-year-old children with developmental dyslexia by means of event-related brain potentials (ERP). Cortical sound reception was evaluated by recording N250 responses to syllables and tones and cortical sound discrimination by analyzing the mismatch negativity (MMN) to syllable and tone changes. We found that both cortical sound reception and sound discrimination were impaired in dyslexic children. The analysis of the data obtained from two dyslexic subgroups, Dyslexics-1 being impaired in non-word reading (or both non-word and frequent word reading) and Dyslexics-2 in frequent word reading but not in non-word reading, revealed that the MM…
Increased homocysteine levels correlate with the communication deficit in children with autism spectrum disorder
2015
The clinical significance of high levels of homocysteine in autism spectrum disorder (ASD) is unknown. An experimental study was conducted in order to evaluate the concentration of homocysteine in children with ASD and typically developing children and to analyse any relationships with the severity of core symptoms of ASD and other clinical features (drugs, co-morbidities, gender, age, diet). Core symptoms of autism were evaluated by DSM-IV criteria. Homocysteine, glutathione, methionine, 3-nitrotyrosine were measured in urine. The increase in homocysteine concentration was significantly and directly correlated with the severity of the deficit in communication skills, but was unrelated to d…
Event-related potentials to pitch and rise time change in children with reading disabilities and typically reading children.
2008
Abstract Objective The purpose of the present study was to investigate whether children with reading disabilities (RD) process rise time and pitch changes differently to control children as a function of the interval between two tones. Methods Children participated in passive oddball event-related potential (ERP) measurements using paired stimuli. Mismatch negativity (MMN), P3a and late discriminative negativity (LDN) responses to rise time and pitch changes were examined. Results Control children produced larger responses than children with RD to pitch change in the P3a component but only when the sounds in the pair were close to each other. Compared to children with RD, MMN was smaller an…
Static postural control in children with developmental dyslexia

Tel.: +33 3 80 24 68 74; fax: +33 3 80 24 11 39.; International audience; The present investigation tries to better understand potential association and causal relationship between phonological and postural impairment due to developmental dyslexia. The study included 50 boys with developmental dyslexia and selected on the basis of their overall reading difficulties, and 42 control boys. Body sway during a quite standing posture eye open and eye closed on a force platform were tested in the two groups of subjects that were between 10 and 13 years of age. Analysis of classical parameters…
The effects of a psychomotor training programme on motor skill development in children with developmental language disorders
1998
Abstract The purpose of this study was to compare the effectiveness of two approaches to movement intervention for children with a combination of language and movement difficulties – a specialist approach labelled psychomotor training and regular PE lessons from trained PE teachers. From a sample of 76 children formally classified as suffering from developmental language disorder, 54 (71%) fell below the 15th percentile on a test of motor competence. These 54 children were then divided into two groups, one of whom received a 10 week psychomotor training programme and the other regular PE lessons. Although all children, regardless of the type of intervention, made progress, the differences b…
