ASD Teaching-Fidelity — Synthetic Video Samples (for review)
These are AI-generated (fully synthetic, no real individuals) short video clips depicting a parent running a naturalistic language-teaching episode with a young child around a picture book. They are samples for reviewer feedback on whether the videos correctly portray each teaching-fidelity level.
Each clip is ~6 seconds, 1216×704, with generated audio (dialogue + room tone).
Fidelity levels shown
The parent uses one of three teaching strategies (mand_model = ask then model, time_delay = cue then wait, modeling = just demonstrate). Fidelity = how correctly the parent delivers it:
| Fidelity | Meaning | What you should see |
|---|---|---|
| 1 — no joint attention | Parent prompts, child not attending | Child disengaged (looks at own hands/sleeve/hair), no shared focus, no response |
| 2 — rushed (no wait) | Child engaged, but parent does not wait ≥3s | Parent fires the next line almost immediately, no expectant pause |
| 3 — waited, no acknowledgment | Parent waited ≥3s but follow-through missing | Two valid forms: child responds but parent does not acknowledge it (responded_not_acknowledged); or child stays silent and parent does not re-prompt (no_response_no_reprompt) |
Note on fidelity 3: about half of the fid3 clips have no child response — that is correct. fid3 requires that the parent waited but did not acknowledge or re-prompt; a child response is not required. The distinction from fidelity 1 is that in fid3 the child is attending (joint attention present) whereas in fid1 the child is disengaged.

How they were made
Text-to-video with LTX-2 (LTX-2.3 22B distilled, HQ two-stage pipeline), a static-camera control LoRA, from gate-verified prompts. No reference image. People and settings are entirely synthetic.
