Language Disorders 2
What is a language delay or disorder?
• Language delay: – Occurs when a child uses language typical for a younger child.
– Sometimes a child is considered delayed when there is a one year discrepancy between their language development age and their chronological age.
• Language disorder: – When the child or adult uses language which is inappropriate regardless of developmental age.

Demographics
• Language disorders comprise the largest caseload for school and pre-school SLPs.

Language Disorders 4
Causes
• Cognitive Delay• Hearing loss• Brain injury or disorder• Learning disability• Autism• Language depravation

Language Disorders 5
Cognitive Delay
• Children with a CD tend to be delayed in all phases of development including . . .– Motor skills– Social development– Self-care– Language– Intellectual and adaptive behavior
• Degree of CD will have an effect on language. – For example, a child with a mild impairment might have only a slight delay, while a child with severe or profound CD may be non-verbal.

Language Disorders 6
Hearing Impairment
• Mild loss– Normally due to otitis media (middle ear infection) and can cause a delay. In most cases these children eventually catch up to their peers.
• Profound hearing loss (Deaf) – Children typically never become proficient in English grammar, but often will use American Sign Language (ASL), which has their own unique syntactic rules.

Language Disorders 7
Hearing Impairment
• High frequency loss – Hearing loss where they may not hear high frequency speech sounds such as /s/ and /d/ which might lead to difficulty with plurals (-s) and past tense (-ed).
• If unaided, children generally are delayed by about one year for every 10 dB of hearing loss.
• Early intervention with hearing aids or cochlear implants is vital for language development.

Language Disorders 8
Brain injury or disorder
• Might be a result of . . .– Cerebral palsy or other neurological disorder
– Traumatic brain injury
![Page 9: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/9.jpg)
Language Disorders 9
Cerebral Palsy
• A neurological disorder that severely affects coordination.
• Besides affecting articulation, children may not talk because of difficulty with coordination.

Language Disorders 10
Traumatic brain injury
• Causes– Result of auto accident– Birth trauma– Gun shot wound other trauma to the brain
• Damage to those areas of the brain important for language.

Language Disorders 11
Learning disability
• Child might have a specific learning disability which prevents them from developing language adequately.
• Sometimes referred to as a functional disorder since there is no none organic cause of the disorder.
![Page 12: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/12.jpg)
Language Disorders 12
Autism
• Autism is behavioral disorder where the children do not interact or minimally interact with others. – This includes verbal interaction.
• Aversion to external stimuli– Noise– Touching– distracting visual stimuli
• May have low, normal or high intelligence and may perform specific tasks very well.
• Important that intervention occurs at an early age.

Language Disorders 13
Language deprivation
• Parents do not talk to children• Multiple children• Children with serious health problems
• Deaf parents• English Language Learners homes• Parents with a CD

Language Disorders 14
Assessment
• Screening• Evaluation
![Page 15: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/15.jpg)
Language Disorders 15
Screening
• Purpose is to test a child to see if a possible problem might exist.
• Might involve a short spontaneous sample which is informally evaluated by a speech-language pathologist.
• Short questionnaire for parents• Formal screening test• Other screening such as hearing and vision
![Page 16: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/16.jpg)
Language Disorders 16
Evaluation
• Language sample• Case history• Formal testing
![Page 17: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/17.jpg)
Language Disorders 17
Language sample.
• MLU• Language structure (use of syntax) and semantics.
![Page 18: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/18.jpg)
Language Disorders 18
Case history
• Child’s birth and neonatal history• Child’s medical history• Family history• Child’s developmental history (e.g., when did they start walking, talking, when did they first say two words, etc.)
• How does the child use receptive and expressive language at home
• Anything else not addressed.
![Page 19: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/19.jpg)
Language Disorders 19
Formal testing
• Standardized tests used to assess expressive and receptive language.
• Goal of these tests is to evaluate specific linguistic areas (e.g., rules of morphology or syntax) and knowledge of semantics.
• Other testing including psychoeducational testing, vision and hearing.

Language Disorders 20
Language Treatment
• Treatment plan • Sequence of treatment• Treatment methods
![Page 21: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/21.jpg)
Language Disorders 21
Treatment plan developed by SLP
• E.g., the child might have difficulty with morphology or specific areas of syntax such as preposition, adjectives, or other parts of speech.
![Page 22: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/22.jpg)
Language Disorders 22
Sequence of treatment.
• Typically begins at a level child can master
• Gradually increases task complexity
![Page 23: Language Delays and Disorders](https://reader035.vdocument.in/reader035/viewer/2022081513/568135e7550346895d9d5c55/html5/thumbnails/23.jpg)
Language Disorders 23
Treatment methods
• Modeling, and self talk (SLP or others speaking out loud)
• Behavior modification– E.g.,”repeat after me”, “say this”, etc.
• Cognitive approach– Work on concepts and socialization instead of language directly. Seems to work well with socially disadvantaged children.
