A child with discourse problems would most benefit from remediation focusing on

• A. Morphology
• B. A lexicon expansion
• C. Gestural communication
• D. Cohesive devices

Answer: (B)

Discourse across sentences depends on having a rich, precise vocabulary to label events, actions, attributes, and relationships. When a child’s lexicon expands, they gain more content words to express meaning, which allows them to describe needs, tell stories, and recount events with details. This richer word knowledge makes sentences more informative and easier to follow, and it provides the semantic building blocks that help connect ideas across sentences in a coherent way. As vocabulary grows, choosing appropriate terms becomes easier, which also supports the use of cohesive cues and logical sequencing in talk. While grammar and gesture can aid communication, focusing on increasing vocabulary gives the essential material the child needs to express discourse more effectively.
