NCT ID: NCT06275815 Recruiting - Clinical trials for Developmental Language Disorder

Promoting Caregiver Implementation of an Effective Early Learning Intervention

Start date: April 10, 2024
Phase: N/A
Study type: Interventional

The goal of this study is to examine the impact of a caregiver-implemented shared reading program, Sit Together and Read (STAR), on children ages 4 to 5 with developmental language disorder. The main questions it aims to answer are: - how much STAR impacts children's literacy skills in the short-term and long-term--up to two-years after completing STAR. - how do caregiver supports in the form of small monetary rewards or encouraging texts help caregivers to implement STAR at its intended frequency of sessions per week. Caregiver participants will be assigned to either a control group or one of three STAR groups. Children's skills related to literacy and learning will be assessed before the intervention starts, at the end of the intervention, and every six months post-intervention for two years. Researchers will determine the short term and long term impacts of STAR compared to the control group. Researchers will compare the three STAR conditions to see if the rewards or encouragement helped parents to follow through with completing more STAR sessions.

Using Neuroimaging and Behavioral Assessments to Understand Late Talking

Start date: January 19, 2024
Phase: N/A
Study type: Interventional

Late talkers (LT), representing 10-20% of children under 3, demonstrate hallmark syntax and vocabulary deficits similar to preschoolers with developmental language disorder. While effective and early interventions can mitigate the impact of late talking, not enough is known about its neural basis, yet is needed to inform the design of more individualized interventions. This proposed effort uses neuroimaging, along with behavioral methods, with the goal of better understanding the memory-language mechanisms that underlie learning and late talking, while also considering their association to treatment-related changes in LT.

The Relationship Between Child Language Proficiency and Language of Treatment on the Outcomes of Bilingual Children With Developmental Language Disorder

Start date: August 8, 2023
Phase: N/A
Study type: Interventional

Of the 12 million children in the USA growing up bilingual, about 1 million experience Developmental Language Disorder (DLD), a disorder in language learning and use. Currently there is no guidance for speech language pathologists (SLPs) as to the language of intervention for bilingual children with DLD with differing degrees of proficiency with English or Spanish. This project will examine the relationship between relative language proficiency and the language of intervention, considering monolingual intervention in English and Spanish and bilingual intervention presented by alternating English and Spanish treatment sessions with the goal of improving language outcomes and thereby strengthening long-term academic achievement.

Retrieval-Based Word Learning in Developmental Language Disorder During Book Reading

Start date: October 31, 2022
Phase: N/A
Study type: Interventional

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 well-being. 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 the investigators' previous work to determine whether, as has been found thus far, special benefits accrue when these children must frequently recall newly introduced words during the course of learning. In this study, the investigators seek to replicate the advantage that repeated retrieval holds over simple exposure to the words and to demonstrate an increase in children's absolute levels of learning by implementing retrieval practice in the context of a story book.

NCT ID: NCT05953077 Recruiting - Clinical trials for Developmental Language Disorder

The Effect of Prior Learning on Treatment of Morpheme Errors

Start date: June 7, 2023
Phase: N/A
Study type: Interventional

This is a small-scale treatment study designed to determine which teaching methods result in the best learning. Treatment focuses on helping children with a developmental language disorder learn parts of grammar. Preschool children will receive assessments to determine whether they have a developmental language disorder and what parts of grammar they have not mastered. Children will receive one-on-one behavioral treatment over a six week period. Half of the children will be first taught a grammatical form they sometimes use and then one they rarely use. The other half will start with a grammatical form they rarely use. The study seeks to determine whether starting with something children sometimes use correctly (an easier part of speech) will speed later learning of something that is harder for them. The children's ability to use the grammatical forms taught to them will be assessed throughout the treatment period and approximately six weeks after treatment ends.

NCT ID: NCT05921188 Recruiting - Clinical trials for Language Development Disorders

The Effect of Prior Learning on Word Learning

Start date: June 1, 2023
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT05901493 Recruiting - Clinical trials for Developmental Language Disorder

Category Learning Retention in Adults With and Without Developmental Language Disorder

Time2Learn
Start date: October 23, 2022
Phase: N/A
Study type: Interventional

Approximately 7% of the population experiences developmental language disorder (DLD), a language disorder with unclear causes. DLD affects communication beyond adolescence and poses challenges for education and career advancement due to difficulties in learning and memory. Recent research suggests that adults with DLD struggle with overnight memory consolidation, indicating a need for effective learning and memory support. This project aims to determine the optimal training schedule for perceptual memory retention in adults with and without DLD. The study involves recruiting 240 adults (120 with DLD, 120 without) for speech-perceptual training with different training schedules. The researchers predict that the manipulation of training schedules will interact with circadian preference and overnight consolidation, leading to the discovery of the best practice schedule for speech sound retention. Additionally, 300 more adults (150 with DLD, 150 without) will be recruited to investigate how optimal training schedules interact with reflexive and reflective learning strategies. The time course of learning and retention will be tracked during reflexive and reflective categorization training in six different training schedules.

NCT ID: NCT05767242 Recruiting - Development, Infant Clinical Trials

Early Neurophysiological Markers of Language Impairments

Start date: February 21, 2022
Phase:
Study type: Observational

The present project aims at identifying very early electrophysiological risk markers for language impairments. The long-term goals of the study include the characterization of learning developmental trajectories in children at high risk for language impairments. In this project, all the infants of the Medea BabyLab cohort are followed-up until school age. Since these infants have complete information on early electrophysiological markers, the final goal of the project is the characterization of their learning developmental trajectories and the construction of a multi-factor prognostic model that includes the neurophysiological processes underlying basic-level skills as potential biomarkers for predicting later reading and spelling skills.

NCT ID: NCT05678634 Recruiting - Clinical trials for Developmental Language Disorder

Optimizing Feedback-based Learning in Children With Developmental Language Disorder

Start date: July 20, 2023
Phase: N/A
Study type: Interventional

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.
