Learning Disabilities

224
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Higher Mental Functions of the Brain: Language

945
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Summary
This summary is machine-generated.

Deafness does not necessarily impair executive function (EF) in children. Early sign language exposure and deaf parenting support EF development, with sign language skills predicting performance in deaf children.

Area of Science:

  • Cognitive Psychology
  • Developmental Psychology
  • Linguistics

Background:

  • Executive function (EF) is crucial for cognitive development.
  • Previous research has inconsistently linked deafness with EF deficits.
  • The role of sign language in EF development in deaf children is understudied.

Purpose of the Study:

  • To determine if deafness is invariably associated with executive function deficits.
  • To investigate the relationship between sign language proficiency and EF in deaf children with early sign language exposure.
  • To examine EF in children acquiring Polish Sign Language.

Main Methods:

  • Comparative study involving deaf children (N=20) and hearing peers (N=20).
  • Assessment of various executive function tasks, including inhibition (Go/No-go).
  • Evaluation of sign language receptive skills and maternal education levels.

Main Results:

  • Deaf children performed similarly to hearing peers on most EF tasks, despite lower maternal education.
  • Younger deaf children (6-9 years) showed weaker inhibition skills than hearing peers; this difference diminished in older children (10-12 years).
  • Sign language receptive skills positively predicted executive function in deaf children.

Conclusions:

  • Deafness does not necessarily impair executive function.
  • Attentional and inhibition abilities may develop through different pathways in deaf children.
  • Deaf parenting and early sign language exposure are vital for scaffolding executive function development in deaf children.
