NCT07613268
The purpose of this study is to evaluate the effectiveness of the AI-based application "HiDongDong" in improving articulation development in children aged 2 to under 14 years with suspected articulation delays. The program provides individualized language training based on a personalized assessment of vulnerable speech sounds. This trial aims to determine whether the digital therapeutic solution can enhance articulation skills and inform future strategies for language rehabilitation in children.
NCT03586479
Children with Specific Language Impairment (SLI) are slower to learn new words than their peers, placing them at risk for academic failure. In this study, we are improving a storybook reading treatment to help Kindergarten children with SLI learn new words. In this study, we compare three versions of book reading that vary in how often children are tested on, meaning asked to talk about, the words they are learning in the book: low vs. mid vs. high testing. We then examine which version of the treatment leads to better learning of the words during treatment and remembering of the words after treatment. We also seek to understand individual differences in treatment outcomes by examining pre-treatment predictors as well as progress during and after treatment.
NCT05921227
The goal of this clinical trial is to see if providing late talking toddlers who are not responding to the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment with a different way of communicating will help them improve their word learning. Participants will start with VAULT word learning treatment. If, in the first few sessions, it looks like they won't respond well, they will be provided with a Big Mack Augmentative and Alternative Communication device (a button that says a word when you press it) to use for their responses. The investigators will see if this modification will help with word learning.
NCT05921188
The goal of this clinical trial is to compare two treatment conditions for late talking toddlers. In 8 weeks of word learning treatment, toddlers will be taught words that sound more like the words they already know or sound less like the words they already know. The investigators see which group learns more, to understand if choosing words that let children use the knowledge they already have helps with learning.
NCT05921214
The goal of this clinical trial is to compare word learning outcomes in late talking toddlers who are taught different types of words. The main question it aims to answer is if teaching words that come from categories that children already know (e.g., animals) will aid overall word learning. Children will take part in the Vocabulary Acquisition and Usage for Late Talkers (VAULT) word learning treatment and be taught words from more familiar or less familiar categories to see which group learns more words overall.
NCT04384328
Prospective, interventionnal with minimal risks and constraints, multicentric, non-randomized, open study, to measure the impact of an early support programme in speech and language therapy for vulnerable children (PAPEV-ortho), in children born very prematurely or very hypotrophically, on the incidence of language and communication deficits at the corrected age of 2 years.
NCT04926311
Children with Developmental Language Disorder (DLD) have many linguistic difficulties in syntax, lexicon, morphology and phonology. Frequently, they also present co-occurrent (or comorbidities) impairments which further impaired school learning. Thus, they have poor academic outcomes and many of these children have been maintained at least one time in a classroom, sometime more. The purpose of this project is to determine which modalities of speech and language therapy are the more efficient on academic outcomes of children with DLD. The main modalities that will be studied are the duration of speech and language intervention, the age at which begins the intervention and the intensity (number of intervention sessions per week).
NCT05624983
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.
NCT03609502
This study tests a memory-based account of atypical speech perception in adults with language-based learning disability (also known as developmental language impairment \[LI\]). One perspective regarding the its etiology considers impoverished speech sound representations to be central to the linguistic symptoms observed in LI. This project examines a potential abnormality in the process of building speech sound representations in LI. Previous work by the PI has found that sleep is important for learning speech sounds. Furthermore, different measures of speech perception (identification and discrimination), reveal distinct patterns of learning that are consistent with that of declarative and procedural memory consolidation. A division of labor by declarative and procedural memory systems in the building of speech representations may imply that problems with phonology may stem from selective weaknesses in declarative or procedural memory in predictive ways. The first project Aim is to identify the memory substrates of novel phonetic category formation. In Experiment 1, the investigators will obtain behavioral measures of declarative, procedural, and speech sound learning before and after post-training sleep in 40 typical adults and 20 adults with LI. Among typical adults, a double dissociation is predicted in which speech identification will be predicted by individual differences in declarative memory, and speech discrimination will be predicted by individual differences in procedural memory. Moreover, adults with LI are predicted to demonstrate consolidation deficits across memory types. The second project Aim is to identify the neural substrates of phonetic category formation. In Experiment 2, the investigators will obtain functional magnetic resonance (fMRI) recordings of 20 TD and 20 LI adults performing post-training identification and discrimination tasks on a trained speech contrast before and after sleep. In typical adults, a Time by Speech-task interaction is predicted. Speech identification will recruit episodic (hippocampal) information on Day 1 relative to classic regions for phonological processing on Day 2. Speech discrimination will result in a change in magnitude of activation from Days 1 and 2 in the left inferior frontal gyrus (IFG), reflecting an overnight decrease in effort. LI (n=20) is predicted to demonstrate reduced overnight change in neural activation relative to TD in both tasks.
NCT00212576
This project will measure the degree to which parenting programs based in pediatric primary care can be effective in promoting language development and school readiness in at-risk young children. The study is a randomized controlled trial in which two different primary care-based parenting programs will be compared to a control group in a population that is at risk on the basis of poverty. The two programs represent varying levels of low intensity, but each has the same goals: enhancing parent-child interaction in order to improve language, cognitive and social-emotional development and ultimately promote school readiness and school performance. One program is called the "Video Interaction Project". While waiting to see the primary care provider for well child care, the family meets with a child development specialist, who videotapes the parent and infant interacting together. The videotape is then rewound and watched together by the parent (and infant!) and child development specialist. This leads to a discussion about child development, infant cues and parenting, with the child development specialist building on observed strengths in the interaction. In addition, families are provided with parenting pamphlets developed for the project, and with inexpensive developmentally stimulating toys. The other program is called the "ASQ-Building Blocks Project". This project employs a public health approach to facilitate parental engagement in child development. Families are sent monthly newsletters that focus on child development, infant cues and parenting; included with each newsletter is an inexpensive, developmentally stimulating toy. In addition, families periodically receive Ages and Stages Questionnaires, which they complete and mail back to the program. Based on the questionnaires, the program determines whether the infant has screened positive for possible developmental delay and provides this information to both the family and the primary care provider. This study will test 2 hypotheses: 1. Primary care based parenting interventions can impact parent-child interaction, early child development and school readiness. 2. Interventions of differing intensity will have impacts of differing magnitude depending on the risk level of the family.
