49. Developmental Language Delay: Why Verbal Working Memory Matters More Than Grammar at Age 3

If you work with preschoolers or school-aged children with developmental language delay, you won’t want to miss this episode.

Too often, clinicians focus on grammatical morphemes at age three — but research shows that’s unreliable. Instead, the hallmark feature of developmental language delay is poor verbal working memory.

In this episode, you’ll learn:
 ✅ Why grammatical accuracy is not a valid diagnostic marker at age 3
✅ How verbal working memory deficits show up in spontaneous language samples
✅ Why narrative skills are powerful predictors of language impairment
✅ Which standardized tests (like the CTOPP-2) provide meaningful insight
✅ How poor working memory links to shorter utterances, reduced complexity, and narrative breakdowns

If you’ve ever questioned your assessment practices, this episode will give you a research-based framework for identifying developmental language delay in preschool and school-aged children.
