Filter by:The investigators designed the Child-Caregiver Interaction Observation Scale（CCIOS）to assess social communication behaviors, stereotyped behaviors for children with autism spectrum disorder(ASD) via a 20-min video of interactions between a caregiver and a child. The original CCIOS coding scheme consists 23 items. The score range for each item is 0-4, with higher scores being indicative of more atypical behavior. The aim of the study is to determine items for inclusion in the final CCIOS coding scheme through exploration of item correlations, establish the cutoff score of CCIOS for ASD and evaluate the reliability and validity of CCIOS. The reliability evaluation include test-retest reliability and inter-rater reliability. DSM-5 criterion is used as the gold standard. Validity is assessed by determining the correlation and consistency between CCIOS and DSM-5 criterion.
The investigators will assess the efficacy of Pivotal Response Treatment (PRT) in the treatment of communication deficits in children with intellectual disabilities. By collecting information about parent and child functioning before and after PRT, The investigators will be able to determine whether the intervention is effective in improving child communication and reducing parent stress.
Background: - Studies have shown that animals such as monkeys and dogs have excellent sight and touch memory but perform poorly on sound memory tasks. Human brains have certain areas that are important for speaking and understanding language. These areas may be involved in sound and spoken word memory. Researchers want to study these areas of the brain to find out if the memory for sounds requires brain structures that are usually associated with language learning and are unique to humans. Objectives: - To use magnetic resonance imaging to study areas of the brain involved in sound memory. Eligibility: - Healthy right-handed volunteers between 18 and 50 years of age. They must be native English speakers and have completed high school. Design: - The study requires a screening visit and 1 or 2 study visits to the National Institutes of Health Clinical Center. - At the screening visit, volunteers will have a medical history taken. They will also have physical and neurological exams, and complete a questionnaire. Women of childbearing age will give a urine sample. Participants who have not had a magnetic resonance imaging (MRI) scan in the past year will have one at this visit. - At the second visit, participants will have tests of sound memory. They will listen to a set of nonsense words spoken through earphones and memorize the words. Then they will listen to the words again to judge if the words were part of the earlier list. Participants will have a 1 hour break, then do the sound memory test again. During the second test they will have repetitive transcranial magnetic stimulation (rTMS), which stimulates different regions of the brain. - If the group results from the testing sessions are positive, there will be a third visit. At this visit, participants will have a sound perception test. They will listen to words spoken through earphones and judge whether the words in the pair are the same or different. Participants will have rTMS during these tests as well.
The goal of this proposal is to examine the efficacy of a manualized treatment intervention, AMALS: Addressing Multiple Aspects of Language Simultaneously, which is designed to remediate semantic, morphological, and syntactic aspects of language in preschool children with language impairment. This study will target preschool children with language impairment living in a region characterized by nonmainstream dialects. Questions driving this work are: 1. Will children participating in the AMALS treatment exhibit greater semantic, morphological, and syntactic complexity on multiple outcome measures at the completion of the intervention compared to a Discrete Trial Approach (DTA) group? 2. Will these gains be maintained at one-month follow up? 3. What is the impact of dialect on dependent variables, specifically morphosyntactic abilities? To answer these questions a randomized clinical trial will be conducted comparing AMALS, an integrated approach to treatment, with DTA, an additive approach to therapy. In this study rather than restrict the ethnic and cultural backgrounds of this population, children's use of dialect will be uniquely identified and examined.
The specific is to study the MR morphologic and spectroscopic brain correlates and predictors of development in children with severe developmental disorders (autistic spectrum disorders and/or mental retardation and/or language disorders). Given the frequently observed association of autism with known medical conditions, particularly in cases with comorbid mental retardation and in cases with atypical autism (Rutter et al., 1994; Gillberg, 1995), children with suspected autism or related developmental disorders will be asked to participate in an extensive state of the art laboratory work-up which includes T1 and T2 weighted MRI of the brain. MRI data will be analyzed both qualitatively, looking for focal abnormalities and degree of myelination, and quantitatively, measuring volumes of total brain, cerebellum, ventricles and grey and white matter. For research purposes, the work-up will be supplied with proton Magnetic Resonance Spectroscopy (MRS) of the brain. This data set provides the opportunity to chart brain-behavior relationships in young children with suspected autism and related PDD cross-sectionally.
This study will determine baseline language skills in children 4 to 8 years old. The data will be used to design studies using functional magnetic resonance imaging (fMRI) to identify what areas of the brain in children are involved in understanding language. This information is important for children who require brain surgery to control seizures. Healthy normal volunteers between the ages of 4 and 8 years who have an IQ of 70 or more; who have no history of neurologic, psychiatric or language disorder; who are performing at or above grade level, and who are native English speakers may be eligible for this study. Participants will be asked to do the following: - name pictures or read words that appear on a computer screen - listen to stories and answer questions about them - match pictures to a spoken word The children's responses will be recorded.
Some children with certain language disorders may not properly process the sounds they hear, resulting in language impairments. The purpose of this study is to determine if deficits in auditory temporal processing the way the brain analyzes the timing and patterns of sounds are an inherited trait. Families with auditory temporal processing deficits are sought in order to identify the genes responsible for auditory temporal processing deficits. Children and adults with a diagnosis or history of language impairment in the family and their family members both affected and non-affected are eligible for this two-part study. In Part 1, participants undergo a series of language tests and listening tests to measure various characteristics of how they perceive sound. In Part 2, they are interviewed about language disorders, learning disabilities, and other medical problems of family members. This information is used to construct a pedigree (family tree diagram) showing the pattern of inheritance of family traits. Study subjects whose pedigree indicates that language disorders may be hereditary in their family will provide either a small blood sample (1 to 2 tablespoons) or a tissue specimen obtained from a cheek swab (rubbing the inside of the cheek with a small brush or cotton swabs). The sample will be used to isolate DNA for genetic analysis.
