Early motor development and later language and reading skills in children at risk of familial dyslexia.

2005

Relationships between early motor development and language and reading skills were studied in 154 children, of whom 75 had familial risk of dyslexia (37 females, 38 males; at-risk group) and 79 constituted a control group (32 females, 47 males). Motor development was assessed by a structured parental questionnaire during the child's first year of life. Vocabulary and inflectional morphology skills were used as early indicators of language skills at 3 years 6 months and 5 years or 5 years 6 months of age, and reading speed was used as a later indicator of reading skills at 7 years of age. The same subgroups as in our earlier study (in which the cluster analysis was described) were used in th…

How does early developmental assessment predict academic and attentional-behavioural skills at group and individual levels?

2009

The main aim of the study was to explore the ability of a brief developmental assessment to predict teacher-rated learning and attentional and behavioural skills in the first grade of school at both the group and individual levels. A sample of 394 children (181 males, 213 females) aged 4 years were followed to the age of 6 years, and 283 of the children (145 males, 138 females; mean age 7 y 11 mo) were followed further to the first grade (age 7 y) at school. The children were administered a brief but comprehensive developmental assessment (Lene - a neurodevelopmental screening method) at their local child health-care centres at ages 4 and 6 years. In the first grade, teachers completed a de…

Parental contribution to child’s early language and interest in books

1998

The relationships between parents’ age, education, literacy activities and shared reading with the child and children’s language skills and early interest in books were examined in a longitudinal study of 108 children. Parents reported on their children’s lexical and grammatical development by using the MacArthur Communicative Development Inventories (the CDIs) at the ages of 14 and 24 months. The Bayley Scales of Infant Development were administered to the children in a laboratory setting at 24 months. Information on parental background variables was obtained through a questionnaire before the children’s birth. Book reading habits were inquired when the children were 2 years of age. Mother…

The development and predictive relations of play and language across the second year

1999

The play and language development of 171 toddlers was examined at 14 and 18 months by observing their activities on the Symbolic Play Test and by assessing their language skills using the MacArthur Communicative Development Inventories (MCDI) and the Reynell Developmental Language Scales. Additionally, data from the Bayley Scales of Infant Development and the MCDI were obtained at 24 months, in order to investigate how play and language measures taken at 14 and 18 months predict children's development at the age of 2 years. The results showed that the vocabulary production and symbolic play of the 14-month-old toddlers made a unique contribution to their language and cognitive skills at the…

Brain event-related potentials (ERPs) measured at birth predict later language development in children with and without familial risk for dyslexia.

2005

We report associations between brain event-related potentials (ERPs) measured from newborns with and without familial risk for dyslexia and these same children's later language and verbal memory skills at 2.5, 3.5, and 5 years of age. ERPs to synthetic consonant-vowel syllables (/ba/, /da/, /ga/; presented equiprobably with 3,910-7,285 msec interstimulus intervals) were recorded from 26 newborns at risk for familial dyslexia and 23 control infants participating in the Jyvaskyla Longitudinal Study of Dyslexia. The correlation and regression analyses showed that the at-risk type of response pattern at birth (a slower shift in polarity from positivity to negativity in responses to /ga/ at 540-…

Language development, literacy skills and predictive connections to reading in Finnish children with and without familial risk for dyslexia

2010

Discriminative language markers and predictive links between early language and literacy skills were investigated retrospectively in the Jyväskylä Longitudinal Study of Dyslexia in which children at familial risk for dyslexia have been followed from birth. Three groups were formed on the basis of 198 children’s reading and spelling status. One group of children with reading disability (RD; n = 46) and two groups of typical readers from nondyslexic control (TRC; n = 84) and dyslexic families (TRD; n = 68) were examined from age 1.5 years to school age. The RD group was outperformed by typical readers on numerous language and literacy measures (expressive and receptive language, morphology, …

Effects of modelling on children's pretend play.

1989

The effects of modelling on pretend play were studied in children between 2.6 and 3.6 years of age by examining changes both in the action and language-based expressions of pretending. Three modelled scenes were demonstrated with the same realistic toys used by the child in the pre-modelling phase. The results gave support to the idea of the effectiveness of modelling. The effects of the modelled scenes were clearest among children whose pre-modelling play consisted of object-centred actions including few of pretending. The post-modelling play of this subgroup showed better quality of action and language categories and integration measures. Among the decentred players no significant action …

Cognitive skills and Finnish language inflection

1987

Covariation of cognitive processes and mastery of inflectional forms assessed by Berko's method were studied among 2.6–4.3-year-old children. The erroneous inflections produced by the children were analysed in order to discover rules underlying their morphological test responses. The use of the different rules was guided by the children's age and cognitive skills. The effects of contextual task factors varied at different mastery levels of the morphological test. The results indicate the need for concomitant analysis of the interaction between the child's existing level of morphology, cognitive skills and contextual variables of the tasks.

Interest in early shared reading: Its relation to later language and letter knowledge in children with and without risk for reading difficulties

2004

Children’s interest in shared reading (14 and 24 months) and its relation to their later language and letter knowledge (age 3;6) were investigated in a follow-up study. The participants were 156 children and their mothers. Half of these children ( N = 74) came from families where one or both of the parents were diagnosed as reading disabled (the at-risk group), the other half ( N = 82) belonged to the control group. The results revealed that children with and without familial risk for reading difficulties did not differ from each other in the interest they showed towards shared reading. Interestingly, only children in the control group appeared to benefit from shared reading interactions i…

Task-related variation in communication of mothers and their sons with learning disability

1995

The purpose of the present study was to examine whether mother-child communication patterns vary as a function of the type of the task. Groups of learning disabled (LD=30) and normally achieving boys (NLD=30) were videotaped interacting with their mothers in two different tasks. The children were matched for age (8 to 11 year-olds) and for parent’s SES. The results indicated that the teaching task differentiated the groups more than did the story task. Academic character of the teaching task increased mothers’ task involvement in both groups. Mothers of the LD group showed, however, significantly more dominance and expressed less emotionality while teaching their child. Mothers’ interaction…

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 Deviances and Clarity Among the Mothers of Normally Achieving and Learning-Disabled Boys.

1994

The main purpose of the study was to reexamine the association between maternal communication deviances and learning disabilities in children. In this study, we adapted and extended the procedure used by Ditton, Green, and Singer (1987). A two-part experimental task was used: one in which the child could not request any clarification of mother's instructions, and another in which the mother and child could communicate. Both communication deviances and the clarity of mothers' communication were analyzed. The subjects were 60 mother-child pairs in which half of the children had learning disabilities and the other half were normally achieving children matched for age and parents' SES. The dyad…

Parents as Informants of their Child's Vocal and Early Language Development

1996

Continuity in vocalization and language development was examined in the longitudinal study of 94 children. Parents observed their infant's vocal development with the help of a checklist during the first year of life and reported their lexical development by using the MacArthur Communicative Development Inventories (the CDIs) at the ages of 14 and 18 months. The Reynell Developmental Language Scales (the RDLS) were administered to the children in a laboratory setting at 18 months. The vocalization checklist revealed milestones of sound production which parents reported reliably and which were significantly related to the child's later language development. The continuity in vocal and languag…

Social interactional behaviors and symbolic play competence as predictors of language development and their associations with maternal attention-dire…

1999

Abstract Children’s early social interactional behaviors and symbolic play competence were studied at 14 months in a sample of 111 mother-infant pairs. The categories of social interactional behaviors, joint visual attention, socially coordinated and object oriented interactions were assessed via observations of mother-infant joint play. An index of symbolic play was derived from the child’s solitary play, which was assessed independently. We examined both the interrelations of these two types of early language predictors, and their relation to children’s language skills and maternal attention-directing strategies. Measures of children’s language comprehension and production were obtained u…

Trajectories of reading development: A follow-up from birth to school age of children with and without risk for dyslexia

2006

In order to understand why some children are vulnerable to difficulties in their language development and their acquisition of reading skill, the Jyväskylä Longitudinal Study of Dyslexia followed 200 Finnish children from birth to school age. Half of these children had a family history of reading problems and were considered at risk for dyslexia; the other half were not at risk. A novel analysis, mixture modeling, revealed four subgroups with differential developmental trajectories to early reading. The subgroups who showed either a “dysfluent trajectory” (n = 12; 11 at risk vs. 1 control) or a “declining trajectory” (n = 35; 24 vs. 11) contained more children with familial risk for dyslexi…

The interaction of language and thought in children's language acquisition: a crosslinguistic study

1997

The purpose of this research was to investigate the potential interaction of conceptual representations and linguistic systems in the process of language acquisition. Language–thought interactions were studied in 80 American, 48 Finnish and 48 Polish preschool children. The research focused on the conceptual and linguistic development of space and time. The spatial and temporal conceptual tasks were designed to measure the transition from experiential to inferential knowledge of space/time representations. In the linguistic domain, comprehension and production tests were used to evaluate the children's capacity to understand mono- and bi-referential location in space and time, where mono-re…

The Development of Spatial Location in Finnish

1991

Abstract The purpose of this research was to study the shift from mono- to bi-referential spatial location in the language of Finnish children. Monoreferential location is based on the intrinsic properties of a referent object and the proximity relationship, and bireferential location requires coordinated spatial relationships involving referent objects and a projective relationship. Locative expressions which are monoreferential include: in/on/under and intrinsic front/back, and those which are bireferential include deictic front/back and between. A pictorial representation of locative relationships with a sentence-picture matching task was used to present the mono- vs bi-referential contr…

Developmental pathways of children with and without familial risk for dyslexia during the first years of life.

2002

Comparisons of the developmental pathways of the first 5 years of life for children with (N = 107) and without (N = 93) familial risk for dyslexia observed in the Jyvaskyla Longitudinal study of Dyslexia are reviewed. The earliest differences between groups were found at the ages of a few days and at 6 months in brain event-related potential responses to speech sounds and in head-turn responses (at 6 months), conditioned to reflect categorical perception of speech stimuli. The development of vocalization and motor behavior, based on parental report of the time of reaching significant milestones, or the growth of vocabulary (using the MacArthur Communicative Development Inventories) failed t…

Early development of children at familial risk for Dyslexia—follow-up from birth to school age

2004

We review the main findings of the Jyväskylä Longitudinal study of Dyslexia (JLD) which follows the development of children at familial risk for dyslexia (N = 107) and their controls (N = 93). We will illustrate the development of these two groups of children at ages from birth to school entry in the skill domains that have been connected to reading and reading disability in the prior literature. At school entry, the highest score on the decoding task among the poorer half (median) of the at risk children--i.e. of those presumably being most likely genetically affected--is 1 SD below the mean of the control group. Thus, the familial risk for dyslexia shows expected consequences. Among the e…

Language problems in children with learning disabilities: do they interfere with maternal communication?

2004

In this study, parent-child interaction in two carefully matched subgroups—school—age boys with learning disabilities (LD) who showed a discrepancy between their verbal IQ and performance IQ and had more extensive difficulties in higher-level language abilities (VIQ < PIQ, n = 8) and boys with LD who did not manifest a discrepancy between verbal IQ and performance IQ (VIQ = PIQ, n = 8), were investigated. The effects of the child's language problems on child task performance and on the quality of maternal communication were analyzed in a mother-child problem solving task. Children in the VIQ < PIQ group were found to be less successful on the task than children in the VIQ = PIQ group…

Early intentional communication as a predictor of language development in young toddlers

1999

Interrelations between various types of early intentional communi cation measures, and their relations to children's concurrent and subsequent language skills and maternal interactional sensitivity were studied in a sample of 111 mother-infant pairs. Intentional communication was assessed at 14 months of age using a composite of early actions and gestures derived from parental reports (MacArthur Communicative Development Inventories, MCDI), and measures of early joint attentional behaviours obtained via observations of parent-child play interaction. The sum of actions and gestures and the measures of joint attentional behaviours correlated significantly with each other suggesting that the …

Shared reading interaction in families with and without genetic risk for dyslexia: implications for toddlers’ language development

1999

Shared reading represents a unique context for language learning. Little is known, however, about the quality of shared reading and its developmental implications in families with reading disabilities. In the present study, these questions were addressed in the context of a longitudinal follow-up. Maternal interactional behaviors and children's participation in a book reading situation were analyzed at 14 months of age in a subsample involving 39 mothers who were diagnosed as reading disabled and had a familial background of reading difficulties (the RD group) and 89 normally reading mothers (the NR group) and their children. Information on the children's concurrent and subsequent vocabular…

Co-occurrence of developmental delays in a screening study of 4-year-old Finnish children

2004

The aim of this population study was to examine the severity and prevalence of co-occurring developmental delays in 4-year-old children, the rate of overlapping problems, and sex differences. A sample of 434 children (196 males, 238 females; mean age 4 years 3 months, SD 1 month) were administered the 'Lene' test: a comprehensive neurodevelopmental screening test. Results suggest that co-occurrence of attention-behavioural, motor-perceptual, and language delays occurring in school-aged children could already be detected at the age of 4 years. Isolated delays were usually mild, but co-occurring difficulties were mostly moderate or severe. Overlap between developmental delays depended on the …

Language Development and Symbolic Play in Children With and Without Familial Risk for Dyslexia

2001

The purposes of this study were to investigate (a) whether children in families with a positive history of dyslexia were more likely to show delays in language development than children without family risk and (b) whether a delayed onset of expressive language (late talking) predicted later language development. We analyzed the language development of 200 children longitudinally at 14, 24, 30, and 42 months and assessed their symbolic play at 14 months. Half of the children ( N =106) were from families with a history of dyslexia (the Dyslexia Risk [DR] group), and other children served as age-matched controls. Parental reports and structured tests were used to assess children’s receptive a…

The play and language behavior of mothers with and without dyslexia and its association to their toddlers' language development.

2004

The play and language behavior of mothers with ( n = 49) and without ( n = 49) specific reading disabilities (RD) was investigated during play with their 14-month-old children. The contribution of maternal behavior to the language development of their children was examined. The children's receptive and expressive language skills were assessed longitudinally at 14, 18, and 30 months, using the MacArthur Communicative Development Inventories and the Reynell Developmental Language Scales. Children with and without familial risk for RD did not differ from each other in any play or language measures at these ages. No group differences were found for mothers' manifestations of nonsymbolic play a…

Development of early motor skills and language in children at risk for familial dyslexia

2007

Differences in motor development and the relationship between motor and language development were studied in 88 children with familial risk for dyslexia (43 females, 45 males; at-risk group) and 88 children without familial risk for dyslexia (35 females, 53 females; control group; n=176) during the first two years of life. A structured parental questionnaire was used to assess motor development. Expressive language skills were assessed at the age of 18 months with the Reynell Developmental Language Scales and at 18 and 24 months with the MacArthur Communicative Development Inventories. At group level, the motor development of children in both the at-risk and control groups was similar. Howe…

Mother-Child Teaching Strategies and Learning Disabilities

1994

The teaching strategies used by mothers of sons with learning disabilities (LD) (n = 30) and normally achieving sons (NLD) (n = 30) were examined. The children were matched for age (8- to 11-year-olds) and for parents' socioeconomic status. The behavior of mother-child pairs was videotaped in a teaching task that was constructed to resemble a homework assignment. The results showed that the mothers of children with LD used fewer high-level strategies, and their total time used in teaching was less than that of the mothers of NLD children. The mothers of children with LD exhibited more dominance and less emotionality and cooperation than did the mothers of NLD children; however, the mothers…

Developmental trends in children's pretend play.

1991

The developmental trends in pretend play were investigated in children 2-6 years of age (18 in each of five age groups) by examining changes in pretend action and speech separately. Play behaviour was assessed by using a selected set of Duplo Lego toys. Interest focused on occurrence of decentration, decontextualization and integration at different age levels. The proportions of decentred and decontextualized acts, action integrations and play themes, increased linearly with age. Changes in substitutive and inventive actions were, however, more minor than expected. Single-scheme combinations did not reveal any essential aspect of the development of children's symbolic competence. In this se…

Language and Symbolic Play in Toddlers

1997

Language-play relations were examined in 110 18-month-old toddlers by observing their play actions in the Symbolic Play Test and assessing their language skills with the CDI parental report and the Reynell Developmental Language Scales. Significant associations between both language comprehension and production (vocabulary, use of suffixes, utterance length) and play were found when percentage of symbolic play was used as the measure of play competence. The total play score which included both functional-relational toy manipulation and symbolic play was not as strongly associated with the language measures. In both play measures relations were, however, higher between play and language com…
