Specific Language Impairment (SLI) is one term for difficulties with language development in children unaccompanied by non-linguistic disabilities, possibly genetic in origin and characterised inter alia by missing grammatical morphemes.
A severe difficulty in some aspect of listening, speaking, reading, writing, or spelling, while skills in other areas are age-appropriate. Also called Specific Language Learning Disability.
A primary language disorder also known as developmental aphasia, dysphasia, childhood aphasia, and language disability. It is thought to be a disorder of language expression, comprehension, or both and demonstrated by uneven language development, poor auditory processing skills, short auditory memory, disordered temporal sequencing, and repetition of auditory patterns.
difficulty with the organized symbol-system communication in the absence of problems such as mental retardation, hearing loss, or emotional disorders.
SLI is a language disorder. This means that the child has difficulty understanding and using words in sentences. Both receptive and expressive skills are typically affected. One of the hallmarks of SLI is a delay or deficit in the use of function morphemes (e.g., the, a, is) and other grammatical morphology (e.g., plural -s, past tense -ed). They omit function morphemes from their speech long after age-matched children with typical language development show consistent production of these elements.
An inherited syndrome that impairs language learning and causes lifelong deficits in sentence comprehension and production, despite otherwise normal cognitive functioning.
Lack of communication skill with no obvious bodily disorder.
Specific language impairment (SLI) is a developmental language disorder that can affect both expressive and receptive language. SLI is a relatively "pure" language impairment, meaning that is not related to or caused by other developmental disorders, hearing loss or acquired brain injury. Some children with SLI may acquire language in the same sequence as normally-developing children, but at a slower rate.
