Communication and Language Disorders Quiz

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.
