Study Notes
Prevalence and Awareness
- Communication and learning disorders are common neurodevelopmental disorders in children, affecting about 15% of youths.
- Despite their prevalence, disorders like language disorder are often overlooked.
Language Disorder
- Language disorder involves difficulties in comprehension or production of language, not attributed to intellectual disability or physical impairments like hearing loss.
- Criteria for diagnosis include persistent difficulties in language acquisition, onset in early development, and functional limitations in communication, social participation, academic achievement, or occupational performance.
Types of Language Disorder
- Late Language Emergence: characterized by significant delays in receptive or expressive language, typically diagnosed in toddlers.
- Specific Language Impairment (SLI): involves marked deficits in language not explained by other conditions, usually diagnosed in preschool or kindergarten.
Assessment
- Language disorder is typically diagnosed through standardized language tests, where scores significantly deviate from the mean.
- Children with language disorder often have average nonverbal IQ scores, indicating specific impairment in language skills.
Areas of Difficulty
- Children with language disorder may have problems in receptive language (understanding) or expressive language (speaking).
- Diagnostic tests assess receptive and expressive vocabulary separately to identify specific areas of difficulty.
Long-term Implications
- Early identification and intervention are crucial to prevent long-term academic, behavioral, and social problems associated with language disorders.
- While some children with late language emergence catch up, a significant portion may face more serious developmental delays, necessitating treatment.
Phonology and Morphology
- Phonological awareness (ability to manipulate sounds) and morphology (study of word structures) are areas commonly affected in children with SLI.
- Phonological errors and difficulties in recognizing morphemes contribute to language difficulties.
Case Studies
- Case studies highlight real-world examples of children with language disorders, emphasizing the importance of early intervention and tailored therapy.
Morphological and Grammatical Errors in SLI
- Children with SLI often exhibit difficulties in mastering morphemes and grammar.
- Errors in grammar include problems with sentence structure, such as incorrect word order or verb conjugation.
- Semantic skills are also affected, leading to delays in word acquisition, understanding of word meanings, and errors in word usage.
Causes of Language Disorders
- Genetic Influences: heritability estimates indicate a strong genetic component in language impairments.
- Brain Abnormalities: some studies suggest structural differences in brain regions responsible for language processing.
- Auditory Perception Problems: difficulties in identifying and differentiating sounds contribute to language deficits.
- Deficits in Rapid Temporal Processing: inability to process auditory information quickly leads to delays in language development.
- Delays in Short-Term Memory: problems in retaining auditory information affect language learning.
- Impoverished Parent-Child Communication: quality of verbal interactions between children with language disorders and their parents may contribute to language delays.
Evidence-Based Treatments
- Discrete Trial Training: used to increase language production by teaching individual words, requests, comments, questions, and complex sentences.
- Targeted Interventions: tailored therapy approaches address specific language deficits, such as morphological or grammatical errors.
