Filter by:This project aims to optimize a critical but understudied ingredient of language intervention provided to children with developmental language disorder (DLD) - feedback. The project will bridge a gap between previous findings in our lab of inefficient feedback processing in DLD and clinical practice by identifying the conditions under which feedback-based learning can be improved in DLD. The investigators hypothesize that the effectiveness of feedback can be significantly enhanced for children with DLD when it is tailored to their unique learning strengths. The rationale for this project is based on evidence that feedback-based learning can be improved by enhancing the dominance of an intact learning system. The project will achieve its aim by manipulating (1) the timing of the feedback (immediate vs. delayed) and (2) the level of the learner's involvement in error correction dictated by feedback (active vs. passive correction). Aim 1 will determine the effect of manipulating feedback timing on learning in 140 school-age children (8-12 years) with DLD. While immediate feedback is processed by the striatum, which is also implicated in implicit learning, delaying the feedback by a few seconds shifts feedback processing to the mediate temporal lobe (MTL)-based declarative learning system. Evidence that delaying feedback improves learning in DLD would support the hypothesis of the implicit deficit theory that intervention should capitalize on declarative learning mechanisms. The project will test a novel alternative feedback-learning parity hypothesis whereby feedback-based learning is optimized when the timing of the feedback is aligned with the dominant learning system at a given time (i.e., immediate feedback during striatal-based probabilistic learning; delayed feedback during MTL-based declarative learning). Within the same group of children, Aim 2 will compare feedback-based learning in children with DLD when feedback (a) prompts active self-correction or (b) passively exposes learners to error corrections (corrective recast). Children will engage in two nonword-object paired-associate learning tasks. In one task, feedback will promote active self-correction, which is in line with declarative learning. In the other task, feedback will passively expose the learner to corrective feedback in a manner consistent with teaching approaches aiming at reducing awareness of errors. The project will determine whether children with DLD learn better when feedback prompts self-correction or when they are exposed to passive corrections. Electrophysiological measures will indicate whether passive corrections (corrective recast) are processed as negative feedback by children with DLD. For both aims, behavioral indicators of response to feedback will be complemented by electrophysiological measures of feedback processing that can determine the involvement of the striatum and MTL brain systems during the learning process. This work is scientifically and clinically significant because elucidating what manipulations optimize feedback-based learning will enhance our understanding of the impaired learning mechanism in DLD and will provide clinical guidance on what type of feedback to use during an intervention.
The goal of this randomized control trial is to test the efficacy of the Social ABCs 6 week, group-based model using a virtual delivery platform. The Social ABCs is a caregiver-mediated early intervention program, aiming to increase child skills in directed, intentional vocalizations, and shared smiling with a primary caregiver for toddlers identified as early signs or a confirmed diagnosis of autism spectrum disorder (ASD), or having related social communication challenges. A positive RCT was previously completed using the program's in-person individual, 12-week model, and a pilot study showing preliminary promise of the virtual group-based model has also been published. This adaptation to a virtual, group-based model maintains the core components of the intervention, but allows caregivers to meet and discuss the content as a group from their home environments and complete the program in a shorter timeframe. The main questions it aims to answer are: - Is the Social ABCs virtual group-based model an effective early intervention program for toddlers aged 12-42 months with probable or confirmed ASD, or experiencing social communication challenges, when compared to an active control condition? - Can primary caregivers of these toddlers achieve implementation fidelity in the Social ABCs intervention strategies using the 6-week virtual delivery model? Participants will be randomized into the treatment condition (A) where they will receive the Social ABCs virtual group-based intervention or, into a Control condition (B), where they meet virtually with other caregivers in the control groups over the course of 6 weeks, viewing and discussing 3 didactic presentations around general child development content (not autism- or Social ABCs-specific). Video and questionnaire data will be collected before (Time 0) and after (Time 1) the 6 week period. After an additional 6-8 weeks, the same data will be collected from both groups as a follow-up time point (Time 2). Researchers will compare the Treatment group and the Control group to measure change in the target behaviours for the child, the caregiver's use of strategies, as well as caregiver stress and self-efficacy, across time-points.
Among the objective non-invasive audiological explorations the distorsion products of otoacoustic emissions (DPOAE) allow to quickly assess the function of the cochlear outer hair cells (without the active participation of the subject). This technique is used in newborn screening. While humans are able to perceive sounds in a frequency range of 20Hz to 20kHz, routine clinical audiological assessment is only concerned with frequencies between 1-4kHz. This obscures the importance of high frequencies (HF) which can be easily assessed by DPOAEs. In young children, the perception of these high frequencies could also play an important role in language acquisition. The main objective of this study is to evaluate the relationship between subtle high-frequency hearing impairment, as assessed by the DPOAE (non-invasive, rapid and simple audiological test), and language delay or difficulties in a pre-, peri- and school-age pediatric population.
This study aims to pilot a world-first intervention, a mental health intervention augmented for children indicated with developmental language disorder (DLD). It serves as a proof-of-concept of how existing observational studies on these topics at the Centre for Research in Child Development (c.f. Tran-Sen; Gibber) can be translated into interventions. Mental health problems here are defined as anxiety type problems of social anxiety, specific phobia, separation anxiety and generalised anxiety. DLD is defined as a marked difficulty in oral language in the absence of biomedical causes (Bishop et al., 2017). This randomised pilot answers three uncertainties in preparation for a future definitive randomised control trial (RCT).
The importance of narrative skills is evident in their role in language development and their relation to important academic skills namely reading, comprehension, and writing. Narratives are also essential for competent social skills, and children with delayed language development are usually found to have less proficient social communication skills. Research demonstrates the effects of narrative language intervention on improved narrative structure and complexity in addition to improved receptive and expressive use of syntax, morphology and general language use in children with narrative language impairment in various types of communication disorders. Given the importance of narrative language abilities in language development and due to lack of research targeting the assessment and intervention of narrative language skills of Arabic speaking children with language impairments, this study is dedicated towards the assessment of narrative language in Arabic speaking children and the development of a comprehensive intervention program targeting narrative language skills and its application on children with hearing impairment and developmental language disorder.
This study aimed to evaluate the concurrent validity information of the 24-, 30-, and 36-month Indonesian ASQ-3 with the Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) in Indonesian children. Children living in Tanah Tinggi subdistrict, Central Jakarta, were recruited conveniently from November to December 2019. Children within the 24-, 30-, or 36-month age group were assessed for Indonesian ASQ-3 concurrently with BSID-III as the reference standard according to their age groups. Screening test accuracy was measured in sensitivity, specificity, and predictive values for both overall dan specific domains.
This study aimed to provide the validity and reliability of the Indonesian ASQ-3 questionnaires as a screening tool for developmentally delayed children aged less than one year old. This study was divided into 2 phases. The first phase (April-June 2018) included the transcultural adaptation of the ASQ-3 questionnaires for 2 to 12 months age groups from English to Indonesian. The second phase (July- September 2018) included a cross-sectional study of Indonesian ASQ-3 questionnaires for parents/caregivers of children aged 1-12 months, with 35 children in each age group by cluster sampling methods, in 2 district areas in East Jakarta.
Children with developmental language disorder (DLD; also referred to as specific language impairment) experience a significant deficit in language ability that is longstanding and harmful to the children's academic, social, and eventual economic wellbeing. Word learning is one of the principal weaknesses in these children. This project focuses on the word learning abilities of four- and five-year-old children with DLD. The goal of the project is to build on our previous work to determine whether, as we have found thus far, special benefits accrue when these children must frequently recall newly introduced words during the course of learning. In this first of a series of studies, we seek to increase the children's absolute levels of learning while maintaining the advantage that repeated retrieval holds over comparison methods of learning.
The main purpose of this study is to investigate if the internet-based computer-game Grapholearn (GL) is an effective tool for early and intensive intervention of the reading decoding skills in Swedish children with DLD, as compared to two control groups of children with DLD (I) playing a math computer game, and (II) attending usual schooling. Hypothesis: Five weeks of 20 sessions of GL will improve the accuracy of word and nonword decoding skills in children with DLD from baseline to T2 and T3. The GL intervention group will perform higher number of accuratly decoded words and nonwords than the two control groups at T2, and at T3. The second aim is to elucidate how the parents' language and reading skills, prevalence of language-related diagnoses, and socio-economic-status, and the children's self-reported self-esteem is related to their reading skills. Hypothesis 1: Children with DLD who's parents show poor language and/or reading skills will perform lower on the word/nonword decoding tests. Hypothesis 2: Children who show no significant improvement of word/nonword decoding skills will to a higher degree have parents with reading difficulties. Hypothesis 3: Parents highest level of education will not be associated with the participating childrens language and reading skills. Hypothesis 4: Results from the self-reported self-esteem will be lower than normdata from the test manual, and will not be associated with the children's language and reading skills.
Children with developmental language disorders (DLD, aka specific language impairment), a prevalent pediatric disorder, experience hallmark grammar deficits with life-long impacts on educational and occupational outcomes. While effective and early interventions can mitigate the impact of DLD, not enough is known about the neural basis of DLD in young children, yet is needed to inform the design of more individualized interventions. This project uses neuroimaging, along with behavioral methods, with the goal of better understanding the memory-language mechanisms that underlie grammar learning and impairment, while also considering their association to treatment-related changes in preschoolers with DLD.
