Does the Amount of Time Mothers Spend With Children or Adolescents Matter?
Bibliographic record
Abstract
Although intensive mothering ideology underscores the irreplaceable nature of mothers' time for children's optimal development, empirical testing of this assumption is scant. Using time diary and survey data from the Panel Study of Income Dynamics Child Development Supplement, the authors examined how the amount of time mothers spent with children ages 3–11 ( N = 1,605) and adolescents 12–18 ( N = 778) related to offspring behavioral, emotional, and academic outcomes and adolescent risky behavior. Both time mothers spent engaged with and accessible to offspring were assessed. In childhood and adolescence, the amount of maternal time did not matter for offspring behaviors, emotions, or academics, whereas social status factors were important. For adolescents, more engaged maternal time was related to fewer delinquent behaviors, and engaged time with parents together was related to better outcomes. Overall, the amount of mothers' time mattered in nuanced ways, and, unexpectedly, only in adolescence.

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.
