Intellectual Disability01:29

Intellectual Disability

653
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Quantitative Assessment of Cortical Auditory-tactile Processing in Children with Disabilities

11.2K
Objective and easy measurement of sensory processing is extremely difficult in nonverbal or vulnerable pediatric patients. We developed a new methodology to quantitatively assess infants and children's cortical processing of light touch, speech sounds, and the multisensory processing of the 2 stimuli, without requiring active subject participation or causing discomfort in vulnerable...

Assessing Working Memory in Children: The Comprehensive Assessment Battery for Children – Working Memory (CABC-WM)

30.7K
Working memory predicts a significant amount of variance for a variety of cognitive tasks, including speaking, reading, and writing. However, few tools are available to assess working memory in children. We present an innovative, computer-based battery that comprehensively assesses different components of working memory in school-age...

Metacognitive Development: How Children Estimate Their Memory

11.3K
Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville
Human memory is fallible, and people often cannot accurately recall what they have seen or heard. Adults are aware of their limited memory capacity, so they use strategies, such as rehearsal and mnemonic devices, to improve their recall of important information. Because adults understand the limits of memory, they know it makes more sense to write down the items on their shopping list rather than to try...

Portable Intermodal Preferential Looking (IPL): Investigating Language Comprehension in Typically Developing Toddlers and Young Children with Autism

19.0K
A reliable home-based way to assess the language comprehension of very young typically developing children, as well as those with autism, is described. The method analyzes children's eye gaze while viewing side-by-side images but hearing an audio that matches only one image. Stimuli are designed with young participants in...

Summary

Children with intellectual disabilities (ID) show delayed syntax development. Remarkable progress in syntax abilities occurs after reaching a mental age of 7-9 years, indicating a critical developmental window.

Area of Science:

  • Developmental Psychology
  • Linguistics
  • Neurodevelopmental Disorders

Background:

  • Children with intellectual disabilities (ID) exhibit significant delays in syntactic development compared to other language skills.
  • Investigating the specific conditions influencing syntactic development in Japanese children with ID is crucial.

Purpose of the Study:

  • To examine the syntactic development in native Japanese-speaking children with intellectual disabilities.
  • To compare syntactic abilities between children with ID and typically developing children of the same mental age.

Main Methods:

  • A comparative study involving 51 children with ID (including autism spectrum disorders and Down syndrome) and 78 typically developing children.
  • Assessment of spoken language syntax through receptive and production tasks, matched for mental age.

Main Results:

  • Children with ID demonstrated significantly delayed syntax development compared to typically developing peers with equivalent mental age.
  • A notable acceleration in syntax development was observed once children with ID reached a mental age of 7-9 years.
  • Children with autism spectrum disorders struggled with passive voice acquisition, while Down syndrome presented with broader syntactic delays.

Conclusions:

  • Mental age and the specific type of intellectual disability significantly impact syntactic development.
  • Achieving a mental age exceeding 7-9 years is a key factor for substantial progress in syntax abilities among children with ID.
