Interrelation between Early Motor and Language Development in Infants with Down Syndrome: Preliminary Results

Interrelation between Early Motor and Language Development in Infants with Down Syndrome: Preliminary Results

Perisylvian and Hippocampal Anomalies in Individuals With Pathogenic GRIN2A Variants.

Pathogenic variants in GRIN2A are associated with a spectrum of epilepsy-aphasia syndromes (EASs). Seizures as well as speech and language disorders occur frequently but vary widely in severity, both between individuals and across the life span. The link between this phenotypic spectrum and brain characteristics is unknown. Specifically, altered brain networks at the root of speech and language deficits remain to be identified. Patients with pathogenic variants in GRIN2A offer an opportunity to interrogate the impact of glutamate receptor dysfunction on brain development. We characterized brain anomalies in individuals with pathogenic GRIN2A variants and EASs, hypothesizing alterations in perisylvian speech-language regions and the striatum. We compared structural MRI data from 10 individuals (3 children and 7 adults, 3 female) with pathogenic GRIN2A variants with data from age-matched controls (N = 51 and N = 203 in a secondary analysis). We examined cortical thickness and volume in 4 a priori hypothesized speech and language regions (inferior frontal, precentral, supramarginal, and superior temporal) and across the whole brain. Subcortical structures (hippocampus, basal ganglia, thalamus) and the corpus callosum were also compared. Individuals with pathogenic GRIN2A variants showed increased thickness and volume in the posterior part of Broca's area (inferior frontal gyrus, pars opercularis). For thickness, the effects were bilateral but more pronounced in the left (large effect size, η2 = 0.37) than the right (η2 = 0.12) hemisphere. Both volume and thickness were also higher in the bilateral superior temporal region while the supramarginal region showed increased thickness only. Whole-brain analyses confirmed left-sided thickness increases in Broca's area, with additional increases in the occipital and superior frontal cortices bilaterally. Hippocampal volume was reduced in the left hemisphere. There were no age-dependent effects or corpus callosum group differences. Anomalies in perisylvian regions, with largest differences in Broca's area, suggest an altered development of classical speech-language networks in GRIN2A-related EAS. Left hippocampal reduction suggests a role for this structure in early speech and language development and is consistent with GRIN2A gene expression in that region. Overall, elucidating the neural correlates of EAS provides insights into the impact of GRIN2A dysfunction, opening avenues for targeted intervention in developmental syndromes with compromised speech-language development.

Infants’ brain responses to social interaction predict future language growth

In face-to-face interactions with infants, human adults exhibit a species-specific communicative signal. Adults present a distinctive "social ensemble": they use infant-directed speech (parentese), respond contingently to infants' actions and vocalizations, and react positively through mutual eye-gaze and smiling. Studies suggest that this social ensemble is essential for initial language learning. Our hypothesis is that the social ensemble attracts attentional systems to speech and that sensorimotor systems prepare infants to respond vocally, both of which advance language learning. Using infant magnetoencephalography (MEG), we measure 5-month-old infants' neural responses during live verbal face-to-face (F2F) interaction with an adult (social condition) and during a control (nonsocial condition) in which the adult turns away from the infant to speak to another person. Using a longitudinal design, we tested whether infants' brain responses to these conditions at 5months of age predicted their language growth at five future time points. Brain areas involved in attention (right hemisphere inferior frontal, right hemisphere superior temporal, and right hemisphere inferior parietal) show significantly higher theta activity in the social versus nonsocial condition. Critical to theory, we found that infants' neural activity in response to F2F interaction in attentional and sensorimotor regions significantly predicted future language development into the third year of life, more than 2 years after the initial measurements. We develop a view of early language acquisition that underscores the centrality of the social ensemble, and we offer new insight into the neurobiological components that link infants' language learning to their early brain functioning during social interaction.

Expressive language variation, growth and predictors in Mandarin-exposed young children with autism spectrum disorder

Utilizing the Putonghua Communicative Development Inventory-Toddler Form, this longitudinal study assessed expressive language development (including lexicon, grammar, and decontextualized language) twice over a year’s span in two subgroups (high verbal, low verbal) of 77 2–6-year-old Mandarin-exposed children with autism spectrum disorder (ASD). Both subgroups showed the steeper increase of structural language (lexicon and grammar) vs. the flatter growth of decontextualized language. Moreover, children’s initial language skills (but not autism severity or language environment) predicted language outcomes one year later in both groups. The use of decontextualized language also predicted structural language development in the low verbal group. These findings confirmed the uneven expressive language growth across multiple language domains in subgroups of children with ASD and underscored the contribution of early language skills to their expressive language development. Moreover, the slow growth and significant predictivity of decontextualized language warrant targeted intervention in promoting children with ASD’s talk beyond the ‘here-and-now’ situation in communication.

A maturational frequency discrimination deficit may explain developmental language disorder.

Auditory perceptual deficits are widely observed among children with developmental language disorder (DLD). Yet, the nature of these deficits and the extent to which they explain speech and language problems remain controversial. In this study, we hypothesize that disruption to the maturation of the basilar membrane may impede the optimization of the auditory pathway from brainstem to cortex, curtailing high-resolution frequency sensitivity and the efficient spectral decomposition and encoding of natural speech. A series of computational simulations involving deep convolutional neural networks that were trained to encode, recognize, and retrieve naturalistic speech are presented to demonstrate the strength of this account. These neural networks were built on top of biologically truthful inner ear models developed to model human cochlea function, which-in the key innovation of the present study-were scheduled to mature at different rates over time. Delaying cochlea maturation qualitatively replicated the linguistic behavior and neurophysiology of individuals with language learning difficulties in a number of ways, resulting in (a) delayed language acquisition profiles, (b) lower spoken word recognition accuracy, (c) word finding and retrieval difficulties, (d) "fuzzy" and intersecting speech encodings and signatures of immature neural optimization, and (e) emergent working memory and attentional deficits. These simulations illustrate many negative cascading effects that a primary maturational frequency discrimination deficit may have on early language development and generate precise and testable hypotheses for future research into the nature and cost of auditory processing deficits in children with language learning difficulties.

Analysis of Early Childhood Arabic Language Acquisition of The Komunitas Anak Shalih Based on CEFR

Early age is a golden opportunity for children; therefore, early age is called the golden age for children. At this age, the child has extraordinary abilities, so it is good to be developed optimally. It is the golden age for the child to learn and acquire the language without neglecting other aspects. This is done in Komunitas Anak Shalih Tanjung Morawa. While in the Komunitas Anak Shalih, early childhood children at the educational institution are familiarised with hearing the names of objects and conveying them using Arabic. But in the acquisition of Arabic, they do not have a framework standardisation as a reference. Let's call it one of the CEFR. This study will answer questions related to the process of acquiring Arabic for early childhood in the Komunitas Anak Shalih and their speaking skills according to CEFR levels. This study uses a qualitative naturalistic approach using an embedded case study design model or case study. Data collection techniques are observation, interviews, and documentation, with data analysis to reduce data, present data, draw conclusions, and verify. The results found that early childhood language acquisition in the Komunitas Anak Shalih used behaviourism theory, and their speaking skills were at the rudimentary A1 level (PreA1) based on the CEFR.

The Effect of Self-Efficacy on Digital Reading Platforms on Early Childhood English Language Development

Early childhood education is crucial in laying a solid foundation for children's language and literacy development. In an era where digital technology is increasingly pervasive in daily life, it is important to understand how digital reading platforms can influence young children's language development. This study aims to explore the relationship between children's self-efficacy in using digital reading platforms and their English language development. Qualitative research methods were employed, collecting data through participatory observation and interviews with parents and early childhood educators. The research sample consisted of 30 children (aged 4-6 years) who regularly use digital reading platforms in formal and informal learning environments. The results indicate a positive correlation between children's self-efficacy levels in digital reading platforms and their progress in understanding and using English. The practical implications of this research emphasize the importance of strengthening children's self-efficacy and selecting appropriate digital reading platforms to support young children's language and literacy development. This study provides valuable insights for educators, parents, and educational technology developers in designing effective learning strategies for young children in the digital age.

Examining the relations between early language skills and environmental variables and literacy skills: A longitudinal study from 2 to 9 years

A 7-year longitudinal study was conducted as part of the French national cohort ELFE ( N = 1095). The aim was to identify how and why early language skills at 2 years might predict later literacy skills assessed successively at 5, 7, and 9 years (LitSk5y; 7y; 9y). Using one and the same model, we also examined the relations between literacy skills in the three sessions and the potential impact of three environmental variables: the home learning environment (HLE) and two variables related to socioeconomic status (SES), namely, parental education level (PEL) and household income (HInc). The main findings reveal that expressive vocabulary at 2 years is a significant predictor of LitSk5y. No significant link was found for HLE. The other significant links reveal that PEL is associated with LitSk5y and LitSk7y, and HInc with LitSk5y and LitSk9y. The differential impact of these two SES variables is discussed. Moreover, the restructuring lexical model is proposed to explain how the development of early expressive vocabulary is linked to the development of literacy skills via an implicit stimulation of phonemic awareness during the acquisition of new words.

Environmental Education on Sustainable Principles in Kindergartens—A Foundation or an Option?

Preschool education plays an important role because it lays the foundation for a child’s cognitive, social, and emotional development and shapes responsible and informed individuals. Early childhood education teaches values such as sustainability, environmental protection, and social responsibility. By integrating sustainability into preschool education, we are cultivating an environmentally conscious generation that will contribute to a more sustainable and resilient future. The aim of this study was to determine if there are differences in attitudes and knowledge about various aspects of sustainability (such as gardening, plants, food and proper nutrition, and waste recycling) among children attending two different kindergarten educational programs (ecological and language programs). The study was conducted using the F2F-PAPI survey method and included 58 children aged 4 to 6 years. The results showed that children from the ecological program had greater knowledge of sustainability topics than children whose program focused on early foreign language learning (t(44) = 12.542, p = 0.000). Taking into account the desirable diversity of different educational programs in kindergartens, the results suggest that it is necessary to include environmental education to a greater extent as a foundation in the curricula of mandatory regular programs if we are to achieve some of the key sustainable development goals.

Fetal Hemodynamics, Early Survival, and Neurodevelopment in Patients With Cyanotic Congenital Heart Disease

BackgroundFetuses with cyanotic congenital heart disease (CHD) exhibit profound fetal circulatory disturbances that may affect early outcomes. ObjectivesThis study sought to investigate the relationship between fetal hemodynamics and early survival and neurodevelopmental (ND) outcomes in patients with cyanotic CHD. MethodsIn this longitudinal observational study, fetuses with cyanotic CHD underwent late gestational fetal cardiovascular magnetic resonance (CMR) to measure vessel blood flow and oxygen content. Superior vena cava (SVC) flow was used as a proxy for cerebral blood flow. Primary outcomes were 18-month mortality and Bayley Scales of Infant Development-III assessment. ResultsA total of 144 fetuses with cyanotic CHD were assessed. By 18 months, 18 patients (12.5%) died. Early mortality was associated with reduced combined ventricular output (P = 0.01), descending aortic flow (P = 0.04), and umbilical vein flow (P = 0.03). Of the surviving patients, 71 had ND outcomes assessed. Cerebral oxygen delivery was the fetal hemodynamic variable most strongly associated with cognitive, language, and motor outcomes (P < 0.05). Fetal SVC flow was also associated with cognitive, language, and motor outcomes (P < 0.01), and it remained an independent predictor of cognitive (P = 0.002) and language (P = 0.04) outcomes after adjusting for diagnosis. Diminished SVC flow also performed better than other fetal CMR and echocardiographic predictors of cognitive ND delay (receiver-operating characteristic curve area: 0.85; SE 0.05). ConclusionsAmong fetuses with cyanotic CHD, diminished fetal combined ventricular output is associated with mortality, whereas cerebral blood flow and oxygen delivery are associated with early cognitive, language, and motor development at 18 months of age. These results support the inclusion of fetal CMR to help identify patients at risk of adverse ND outcomes.

Early Language Reading Interventions and Reading Skills of Elementary Grade One Pupils in Zambales, Philippines

Learning to read and write is crucial in child’s development during entering formal schooling in grade one. These skills are identified to as language and literacy skills. It also predicts the child’s success later in school as well as in life. Reading and writing were both encompassed in early language literacy which are the foundation skills of a child and it develops as the child grows. This study aimed to determine the effects of the reading intervention strategies used by grade one teachers on the reading performance of grade one pupils in terms of word recognition, reading speed and reading comprehension. The participants in this study were the 23 grade one teachers coming from the 11 schools of the San Antonio District. Findings of the study came up with the following conclusions: Typical teachers of Grade I in San Antonio always use reading intervention strategies in terms of oral language, alphabet knowledge and word recognition, and often use strategies for phonological awareness, fluency and comprehension. The teachers used various activities exclusively for word recognition, fluency and reading comprehension. The learners have a high level of word recognition skills, are fast readers and with an instructional level of comprehension. A positive linear relationship exists between the reading intervention strategies and the learners' level of reading skills. After the investigation on the relationship between the reading intervention strategies and learner’s reading skills, the researcher recommends the following actions.

Social withdrawal behaviour in Nepalese infants and the relationship with future neurodevelopment; a longitudinal cohort study.

Social withdrawal in infants may be a signal of distress and a precursor for non-optimal development. To examine the relationship between infant social withdrawal and neurodevelopment up to 4 years in Nepalese children. A total of 597 Nepalese infants 6-11 months old were assessed with the modified Alarm Distress Baby Scale (m-ADBB), and of these, 527 with the Bayley Scales of Infant and Toddler Development 3rd edition (Bayley-III) during early childhood, and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) and NEPSY-II subtests at 4 years. We examined whether social withdrawal defined by the m-ADBB was associated with neurodevelopmental scores in regression models. Children socially withdrawn in infancy had lower Bayley-III language scores (-2.6 (95% CI -4.5, -0.7)) in early childhood. This association seems to be driven by the expressive communication subscale (-0.7 (95% CI -1.0, -0.3)), but not the receptive communication subscale (-0.2 (95% CI -0.6, 0.1)). There were no differences in the other Bayley-III scores or the WPPSI-IV and NEPSY-II scores at 4 years in children who were socially withdrawn or not. Social withdrawal in infancy was reflected in early language development but not cognitive functioning at 4 years.

Behaviorist Theory in Philippine English L2 Acquisition: Transition Point from L1 Contact

Skinner’s behaviorist theory delineates how a child acquires L1; notwithstanding, what sets the present study apart from Skinner’s findings can be culled-out from the research context itself. This paper validates the principles behind behaviorist theory as proposed by Skinner (1985) taking into account applied linguistics context. Careful scrutiny of data reveals that the explored theory also plays a vital role in the gradual L2 acquisition through meaningful linguistic attempts (e.g., There are persons cutting trees without replanting; His friends Marilyn and Alicia clean the classroom) and reading activities by fostering affirmative learning atmosphere to induce positive language attitude towards L2 acquisition and functionality. Negligible errors in the process of L2 acquisition are attributed to linguistic variability, interlanguage, and inflectional morphology component. This study is advantageous to EFL learners and teachers globally for it highlights some linguistic implications indispensable to interpret the learning rate, lexical range, comprehensible input (CI), and language cognition of L2 students specifically in early language education. EFL educators may be able to provide meaningful linguistic activities by considering the essential tenets of this academic piece as well as the multiculturalism factor to L2 acquisition.

Cortical tracking of visual rhythmic speech by 5- and 8-month-old infants: Individual differences in phase angle relate to language outcomes up to 2years.

It is known that the rhythms of speech are visible on the face, accurately mirroring changes in the vocal tract. These low-frequency visual temporal movements are tightly correlated with speech output, and both visual speech (e.g., mouth motion) and the acoustic speech amplitude envelope entrain neural oscillations. Low-frequency visual temporal information ('visual prosody') is known from behavioural studies to be perceived by infants, but oscillatory studies are currently lacking. Here we measure cortical tracking of low-frequency visual temporal information by 5- and 8-month-old infants using a rhythmic speech paradigm (repetition of the syllable 'ta' at 2Hz). Eye-tracking data were collected simultaneously with EEG, enabling computation of cortical tracking and phase angle during visual-only speech presentation. Significantly higher power at the stimulus frequency indicated that cortical tracking occurred across both ages. Further, individual differences in preferred phase to visual speech related to subsequent measures of language acquisition. The difference in phase between visual-only speech and the same speech presented as auditory-visual at 6- and 9-months was also examined. These neural data suggest that individual differences in early language acquisition may be related to the phase of entrainment to visual rhythmic input in infancy. RESEARCH HIGHLIGHTS: Infant preferred phase to visual rhythmic speech predicts language outcomes. Significant cortical tracking of visual speech is present at 5 and 8months. Phase angle to visual speech at 8months predicted greater receptive and productive vocabulary at 24months.

Empirical research in early infancy language acquisition: A nonsystematic review of literature

This paper unsystematically reviewed the journal publications written in English in the period from 2010 to 2020 on the topic of early infancy language acquisition. The review was through two aspects: language comprehension, and language production. Additionally, this paper also reviewed several frequently used and new research methods and tools. For early infancy language comprehension, empirical studies found evidences on infants’ comprehension of words’ meaning through sounds, especially the comprehension of nouns, the latter was proven to have relevance with nouns’ familiarity and cross-word relations in the nouns. Besides, empirical studies found evidences on infants’ distinguishment between concrete words and abstract concepts. An important factor to influence infancy language comprehension is the social environment that the baby was exposed to, mainly the mother’s speech and her daily life routine (for example, her work). For early infancy language production, empirical studies found evidences on infants’ ability to associate similar sounds with different objects, and measurement for infants’ language outputs were brought forward in another empirical study. Empirical studies also found infants’ language outputs match to words and objects from the environment. Lastly, this paper reviewed the most frequently used technical methods: fMRI and fNIRS technology for investigating neural mechanisms of infancy language processing. There are other new research methods, include large-sample database analysis and quantitative modeling, corpus analysis, language inputs sampling, language model for infancy language acquisition.

Do focused interests support word learning? A study with autistic and nonautistic children.

Although focused interests are often associated with a diagnosis of autism, they are common in nonautistic individuals as well. Previous studies have explored how these interests impact cognitive, social, and language development. While some research has suggested that strong interests can detract from learning (particularly for autistic children), newer research has indicated that they can be advantageous. In this pre-registered study, we asked whether focused interests support word learning in 44 autistic children and a vocabulary-matched sample of 44 nonautistic children (mean ages 58 and 34 months respectively). In a word-learning task administered over Zoom, children were exposed to an action labeled by a novel word. The action was either depicted by their focused interest or by a neutral image; stimuli were personalized for each child. At test, they were asked to identify the referent of the novel word, and their eye gaze was evaluated as a measure of learning. The preregistered analyses revealed an effect of focused interests, and post-hoc analyses clarified that autistic children learned the novel word in both the focused interest and neutral conditions, while nonautistic children only showed evidence of learning in the neutral condition. These results suggest that focused interests are not disruptive for vocabulary learning in autism, and thus they could be utilized in programming that supports early language learning in this population.

Efficacy of the Teaching Early Literacy and Language Curriculum With Preschoolers From Low-Income Families.

The purpose of this study was to test the efficacy of the Teaching Early Literacy and Language (TELL) curriculum package for improving the early literacy and oral language skills of preschoolers from low-income families. In a randomized controlled trial (RCT), TELL was implemented in 30 TELL and 28 business-as-usual classrooms. TELL is a Tier 1 whole-class curriculum package that includes a scope and sequence of instruction, lesson plans and materials, high-quality books, curriculum-based measures (CBMs), and professional development training and coaching. Implementation fidelity was high; however, due to COVID-19 school closures, we did not collect end-of-year data for our third cohort of teachers. Results indicated significant TELL effects on all code-related CBMs and two code-related distal measures as well as receptive and expressive vocabulary CBMs. No significant differences were found on distal measures of oral language/vocabulary or listening comprehension. Results of the present study, paired with findings from an earlier TELL RCT with children with developmental speech and/or language impairments, suggest that children enrolled in TELL classrooms achieve higher outcomes on a variety of code-related and vocabulary measures by the end of their final preschool year. https://doi.org/10.23641/asha.25345708.

"Aha, so that's how it's done!" - parents' voices on an early language and literacy intervention.

The early intervention Språkstart Halland targets children aged 0-3 years. During home visits at 6 and 11 months, library staff deliver gift-packs containing books, toys, songs, and rhymes to promote early language stimulation. Parents are encouraged to engage in 'talk, play, sing, read' activities to support language development. The aim of the present study was to examine parents' experiences of the 6- and 11-month visits and develop an understanding of their general impressions and thoughts regarding the perceived impact of the visits. Parents (n = 15) were interviewed in four focus groups and two one-on-one interviews. Data was analysed using qualitative content analysis. The findings show that the intervention changed the parents' mindset and increased their knowledge regarding early language stimulation. Tools and strategies benefitting the parent-child interaction were gained. A positive experience and personal guidance created motivation for the parents to carry out the language stimulating activities after the visit. Social gains were described. The findings imply usefulness of the intervention in supporting children's language and literacy development.

Speech, language, functional communication, psychosocial outcomes and QOL in school-age children with congenital unilateral hearing loss.

Children with early-identified unilateral hearing loss (UHL) might be at risk for delays in early speech and language, functional communication, psychosocial skills, and quality of life (QOL). However, a paucity of relevant research prohibits strong conclusions. This study aimed to provide new evidence relevant to this issue. Participants were 34 children, ages 9;0 to 12;7 (years;months), who were identified with UHL via newborn hearing screening. Nineteen children had been fitted with hearing devices, whereas 15 had not. Assessments included measures of speech perception and intelligibility; language and cognition; functional communication; psychosocial abilities; and QOL. As a group, the children scored significantly below the normative mean and more than one standard deviation below the typical range on speech perception in spatially separated noise, and significantly below the normative mean on written passage comprehension. Outcomes in other aspects appear typical. There was however considerable within participant variation in the children's degree of hearing loss over time, raising the possibility that this pattern of results might change as children get older. The current study also revealed that participants with higher levels of nonverbal ability demonstrated better general language skills and better ability to comprehend written passages. By contrast, neither perception of speech in collocated noise nor fitting with a hearing device accounted for unique variance in outcome measures. Future research should, however, evaluate the fitting of hearing devices using random assignment of participants to groups in order to avoid any confounding influence of degree of hearing loss or children's past/current level of progress.

Preschool teachers’ beliefs about children, self-efficacy, classroom quality and children’s early language

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers’ beliefs about children, self-efficacy, and children’s early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool children. Results revealed that teachers’ beliefs about children were the only teacher construct that was significantly associated with both receptive and expressive vocabulary gains, after accounting for between-classroom effects. Classroom quality showed a positive trend toward significantly predicting residualized change in children’s receptive and expressive vocabulary gains.
