Assessing Joint Attention Responding and Initiation in Children with Angelman Syndrome
Bibliographic record
Abstract
Background Angelman syndrome (AS) is a rare neurogenetic disorder that overlaps with autism and is associated with severe cognitive, speech and motor impairments. Communication and social deficits are found among children with AS, both of which may be linked to impairments in joint attention. Methods The participants in this study were four children with a genetically confirmed diagnosis of AS, aged 5–10. Children’s joint attention responding and initiation were measured using a modified version of a structured assessment protocol from MacDonald et al. (2006). Results Children’s ability to respond to joint attention bids was less impaired than their ability to initiate joint attention. Conclusions Differences in children’s response patterns are discussed in relation to their characteristics on measures of cognitive, adaptive and language functioning as well as on a measure of autistic symptomatology. A better understanding of the nature of joint attention deficits in children with AS may assist with developing remedial approaches to improve their communication and social skills.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
