Questions: Clinical Linguistics - Language Disorders

Question 1

Broca's aphasia and Wernicke's aphasia differ in their linguistic profiles. Broca's aphasia typically shows:

• A. Fluent speech with comprehension problems
• B. Speech production difficulty with preserved grammar and comprehension relatively better preserved than production
• C. Complete loss of all language ability
• D. Inability to speak but preserved written language

Answer: (B)

Broca's aphasia (non-fluent aphasia) involves difficulty with speech production; speech is slow, effortful, and often grammatically simplified. Comprehension of complex syntax is also affected. Wernicke's aphasia involves fluent but often semantically incoherent speech with comprehension difficulties. These linguistic profiles reflect different locations of brain damage.

Question 2

Why is discourse analysis (examining connected speech in conversation or narratives) important for assessing language disorders beyond standardized testing?

• A. Standardized tests are irrelevant
• B. Discourse reveals natural language use, patterns of word-finding difficulty, turn-taking, pragmatics, and other abilities/deficits not visible in isolated-word or sentence testing
• C. Discourse analysis is not scientific
• D. All language assessment should be standardized only

Answer: (B)

Standardized tests provide comparative data, but discourse analysis reveals how language disorders affect real communication. A person might perform adequately on isolated sentence tasks but struggle in conversation due to pragmatic, turn-taking, or memory difficulties. Discourse analysis provides clinically relevant information.

Question 3

Specific language impairment (SLI) in children is best characterized as:

• A. Low intelligence affecting all cognitive abilities
• B. Language disorder affecting grammatical and morphosyntactic development, despite typical non-verbal intelligence and hearing
• C. Hearing loss
• D. Autism spectrum disorder

Answer: (B)

SLI is a selective deficit in language, particularly morphosyntax, despite normal non-verbal ability and normal hearing. Children with SLI may struggle with grammatical morphemes (tense marking, plurals) while vocabulary development is less affected. This profile reveals that language has distinct cognitive foundations.

Question 4

Understanding linguistic deficits in language disorders is primarily for academic curiosity, not practical clinical use.

• T. True
• F. False

Answer: False

Understanding linguistic deficits directly informs assessment and therapy. A clinician who understands that Broca's aphasia affects production more than comprehension will conduct different therapy than if approaching it as general 'language loss.' Linguistic understanding enables more targeted, effective intervention.

Question 5

Explain how studying language disorders contributes to understanding normal language and supports theory development.

Model answer: Disorders reveal how language components can dissociate. If comprehension is intact but production is affected (Broca's), language has at least two distinguishable systems. If morphosyntax is selectively impaired (SLI), it has distinct cognitive basis. Lesion-behavior correlations (damage at location X causes symptom Y) reveal neural basis of language. Disorders show which abilities are fundamental and which are derived.

Disorders are windows into language architecture. The patterns of preservation and loss in aphasia types, the selective deficits in developmental disorders, and the specific difficulties in autism reveal how language is organized in the mind and brain. This is why clinical linguistics contributes fundamentally to linguistic theory.
