Developmental Coordination Disorder, Age and Play: A Test of the Divergence in Activity-Deficit with Age Hypothesis
Bibliographic record
Abstract
The purpose of this study is to test whether the activity-deficit experienced by children with probable Developmental Coordination Disorder (DCD) increases with age by comparing activity levels of children with movement difficulties to those of peers without movement difficulties. Using a sample of children ages 9 to 14 (N = 581), we examined whether age influences the relationship between DCD and participation in vigorous play activities and whether the impact of age in this relationship is the same for free play versus organized activities. Consistent with previous work (Bouffard et al. 1996), we found no evidence to support the hypothesis that children with DCD become more inactive compared to their peers as they age; however, we do discuss the limitations in our sample and how some differences in the level of organized and free play are evident among cohorts of different ages. Directions for future research in this area are also discussed. $$ 152 words

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.
