What the DTTC Hierarchy Sounds Like
One target word, "funny," at all four levels of the DTTC hierarchy, as the clinician's support fades and the child takes over.
Full transcript
Level 1, simultaneous production: the clinician and child say the word together, slowly.
Clinician and child together: "Funny."
Level 2, direct imitation: the clinician says it, and the child says it right after.
Clinician: "Funny." Child: "Funny."
Level 3, delayed imitation: the clinician says it, there's a pause, and then the child says it.
Clinician: "Funny." Child: "Funny."
Level 4, spontaneous: no model, just a prompt.
Clinician: "You are sooo…" Child: "Funny!"
On screen: move on from simultaneous production and direct imitation after 5–15 correct, and from delayed imitation after 10–15 correct. Mastery at the spontaneous level is 10 correct across 3 sessions. Cues: visual, verbal, whisper, tactile, mime and gestural. Vary prosody: soft, loud, happy, sad, mad and as a question. Developed according to Strand (2020).
