It’s a matter of surgency: Traumatic brain injury is associated with changes in preschoolers’ temperament.
Bibliographic record
Abstract
Traumatic brain injury (TBI) can disrupt cognitive, social, and behavioral functioning. Temperament is often used to reflect emotional and behavioral tendencies in young children, but has never been assessed after TBI. OBJECTIVE: Evaluate whether early TBI disrupts the trajectory of temperament. METHOD: = 69) reported on their child's temperament retrospectively to assess preinjury profiles and at 6 and 18 months postinjury. For each domain of temperament (Surgency, Negative Affectivity, Effortful Control), linear mixed-model analyses were conducted to explore group differences on the rate of change across time. RESULTS: = .33. Children with msTBI showed a lower rate of increase in Surgency compared to children with mild TBI and orthopedic injuries. CONCLUSIONS: Developmental trajectories of Surgency appear to be affected by msTBI. Disruptions in expected developmental trajectories of temperament could underlie some of the sociobehavioral manifestations of TBI in this young age group.

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.
