Cognition and environment are predictors of infants' motor development over time
Bibliographic record
Abstract
ABSTRACT We conducted a longitudinal investigation on the relationships among motor and cognitive development, biological aspects, maternal practices, parental knowledge, and family environments of infants. Forty-nine infants aged between 3 and 16 months participated in the study. They were evaluated through the Alberta Infant Motor Scale and the Cognitive Scale of the Bayley Scales of Infant Development. Their parents answered a questionnaire about biological factors, the Daily Activities of Infant Scale, affordances for motor development (Baby Scale) in the home environment, and the Brazilian version of the Knowledge of Infant Development Inventory. We conducted evaluations in schools for 4 months. Generalized estimating equations, Bonferroni correction, and Spearman's rank correlation coefficient were used. Significant associations were found in the (1) univariate analysis between motor and cognitive development and environmental factors (education level, income, toy availability, physical space, parental practices and knowledge, breastfeeding duration, and school frequency); (2) multivariate analyses between motor development and income, and between father's age and physical space at home. Motor and cognitive developments were concluded to depend on each other, and environmental factors were shown to be more significant in the associations rather than the biological ones, stressing the importance of home, of parental care, and of the experiences children go through along the first years of their lives.

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.
