Filter by: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.
Developmental Language Disorder (DLD) affects approximately seven percent of the population and is characterized by grammatical deficits that cascade into lifelong academic challenges and under-employment. Current treatments for DLD produce good outcomes under ideal, high intensity conditions or when parents have been trained to deliver therapy using intense coaching methods; however, current publicly funded service delivery systems and private-pay reimbursement models do not support treatment being delivered in this ideal fashion for children older than three. This project will examine alternative methods of delivering treatment that may be more feasible under typical conditions and will identify implementation barriers, with the goal of improving long-term outcomes for children with DLD. We hypothesize that feasibility and palatability will influence dose, which will in turn affect the overall language outcomes.
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.
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).
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.
In this study the investigators focus on a subset of at-risk students who find the language of science to be a barrier to the learning of science. These are the nearly 3 million children in the U.S. who have a learning disability called specific language impairment (SLI). Children with SLI present with deficits in spoken grammar and vocabulary and they are 3.9 to 8.1 times more likely to have reading deficits than children in the general population. Specific Aim #1: To determine whether science-relevant language intervention enhances the learning of science concepts in young children who have SLI. Specific Aim #2: To determine whether science-relevant language intervention facilitates generalization of science concepts and practices in young children who have SLI
The present project develops from a wide research line aiming at identifying very early electrophysiological risk markers for neurodevelopmental disorders. Long-term goals of the study include the characterization of language/learning developmental trajectories in children at high risk for language disorders and the implementation of ecological interventions based on enriched auditory experience to be employed to these children in an attempt to modify their atypical developmental trajectory before the emergence and crystallization of any behavioural symptoms and within the early period of known maximum cerebral plasticity. Specifically, the main aim of this study is the development and implementation of an innovative and ecological early intervention based on environmental auditory enrichment (labelled "rhythmic intervention"). This intervention is tested both on a sample of typically developing infants and on a sample of infants at high familial risk for language disorders during a time span between 7 and 9 months of age. The efficacy of the intervention is tested on the electrophysiological markers tested before and after the intervention activities and on the linguistic outcomes within a longitudinal approach. The efficacy of such an intervention is compared to the spontaneous development observed in comparable groups of infants with and without familial risk for language disorders. In addition, only in a group of typically developing infants, a control intervention providing passive exposure to the same auditory stimulation is tested, in order to verify the specific contribution of the active participation of the children to the intervention. The investigators hypothesize that the rhythmic intervention may modify the electrophysiological markers underlying auditory processing and the linguistic skills of all children, with a larger increase in infants at familial risk for language disorders who are specifically impaired in such skills.
Rehabilitation of dyslexic children with (cental) auditory processing disorder. The first group will receive the proposed program the arabic version of differential processing training program and the control group will receive the computer based auditory traing program (CBAT).
The investigators have designed an innovative proof-of-concept trial designed to provide data as to whether the speech difficulties in children with developmental dysphasia (DD) are improved with intranasal inhalations of bioactive factors (BF), produced by macrophages of M2 phenotype (M2-BFs). The rationale for this approach is the ability of central nervous system (CNS) to repair and the important role of macrophages in the regulation of this process. It was found that type 2 macrophages (M2) have anti-inflammatory and neurorestorative potential, in contrast to pro-inflammatory and neurotoxic effects of М1 cells. The influence of M2 is largely realized through the production of a wide spectrum of bioactive factors (cytokines, chemokines, growth factors, neuropeptides, microvesicles etc) that inhibit inflammation, protect neurons from apoptosis, stimulate neurogenesis, the growth and remyelination of axons, the formation of new synapses and activate angiogenesis. This study uses M2-BFs, as therapeutic tool, and intranasal administration focusing on nose to brain transport, as a mode of delivery. Expected clinical effects in treated children: improvement of speech understanding, word formation, grammatical structure of speech and formation of coherent speech.
