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 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.
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.
The purpose of this study is to investigate an immersive virtual field trip (iVFT) on topic specific academic vocabulary for students with developmental language disorder (DLD). DLD is the most common childhood learning disorder with a prevalence of 7.4%(1) and occurs in the absence of a known biomedical condition (e.g., hearing loss, autism, stroke, intellectual disability). DLD affects a person's academic and social function due to difficulty with using and understanding language.(2,3) Approximately half of students with DLD have a deficit in vocabulary that persists through highschool.(4) Once children fall behind in their language and vocabulary development, it is very difficult to catch up generally resulting in a wider gap as they progress through their school years. This deficit can have cascading social, mental health, occupational and financial consequences.(5) There is preliminary evidence that a virtual reality experience such as an immersive virtual field trip (iVFT) was beneficial for facilitating vocabulary and comprehension in general education(6-8) and within targeted populations of students including second language learners(9) and those with learning differences (e.g., autism,(10) attention deficit hyperactivity,(11,12) and dyslexia(13). The term "immersive" refers to a state of heightened sensation when viewing a simulated environment that is superimposed onto a screen with embedded multisensory input (e.g., visual, auditory, proprioceptive).(14) The viewer looks through 3D goggles to block out the present environment resulting in a feeling of presence. These simulated experiences or destinations (e.g., space) are a type of VR referred to as an immersive virtual field trip (iVFT). To date, there is a lack of empirical evidence, explicitly targeting academic vocabulary growth for early grade school students with DLD. In addition, no study has reported on learning outcomes of students with DLD following a VR condition. Therefore, the primary study objective was to compare gains in academic vocabulary measures between a traditional book condition and an iVFT learning condition for young students with DLD.
Patients with Developmental Language Disorder (DLD) or Autism Spectrum Disorder (ASD) have communicational difficulties to adapt their language to context and to interlocutors. These difficulties have long term impacts on education and social life of these patients. Speech language therapists (SLT) helps child and teenagers with pragmatic and communicational disorders. Nevertheless, few research evaluated the efficacy of such interventions. In the present research, the students will do a literature review to identify efficacy intervention's strategies of pragmatic disorders. Then, 2 to 5 patients, aged from 8 to 14 years old, with ASD or DLD and pragmatic disorders, and who haven't intellectual disorder will be recruited. They will come to the faculty of psychology of UCLouvain before the beginning of the intervention. In this pretest session, parents will answer questionnaires et children will have tests in order to evaluate their pragmatic abilities (during 30 minutes), like conversations, role plays, communication referential tasks, etc. This evaluation will be video recorded to code pragmatic abilities. Then, a group intervention of ten sessions will be proposed (1 session per week, 10 weeks). Activities will include role plays, conversations, etc. At the end of the intervention period, a post test session, like the pretest session, will be proposed to evaluate intervention efficacy. The design is multiple study cases. This is the best design to control efficacy of these kind of interventions considering the inter-individual variability of DLD and ASD patients. This study is original since few research evaluated the efficiency of pragmatic intervention. Some studies demonstrated the efficacy of pragmatic intervention in DLD and ASD patients but theses researches were conducted in English-speaking countries. Furthermore, the present research will propose a group intervention, which weren't proposed in the literature to our knowledge (individual intervention). If the group intervention is efficacy, the cost-benefice ratio would be interested.
This broad aim of this clinical study is to assess the hypothesis that morphological and phonological deficits are linked by a broader deficit in sequential pattern learning. This hypothesis applies to learning in general, but is especially critical as an avenue for developing earlier assessments and more powerful interventions for children with developmental language disorder (DLD; AKA specific language impairment). Other populations, such as at-risk toddlers, may also benefit from this new approach.
This study is a randomized clinical trial that uses a Sequential Multiple Assignment Randomized Trial (SMART) study design. The study will directly compare the efficacy of an innovative intervention that combines explicit and implicit approaches to a traditional implicit treatment approach to teach true grammatical forms to children with developmental language disorder (DLD). The study will also compare interventions that include sequences of Explicit-added and Implicit-only treatments. Participants will include 5- through 9-year-old children with DLD who present with significant grammatical weaknesses. In Phase 1, 155 participants will be randomized 1:1 to an Explicit-added treatment group or an Implicit-only treatment group. Each participant will complete 32 sessions targeting four unique grammatical forms (8 sessions/form). In Phase 2, "Masters" will be re-randomized to receive no treatment 32 sessions of the same treatment, or 32 sessions of the alternative treatment. "Non-Masters" will be re-randomized to receive 32 additional sessions of the same treatment or 32 sessions of the alternative treatment. Performance will be measured on acquisition, maintenance, and generalization probes obtained immediately,1-, 6-, and 12- months post-intervention. The SMART study design will be used to determine if child factors, including expressive and receptive language abilities, nonverbal IQ, and executive function skills can reliably predict the treatment sequence that optimizes language learning. Study results will help to determine the best sequence approach to ameliorate grammatical weaknesses, one of the core deficits of young children with language impairment.
