Abstract

fetched live from OpenAlex

Early life experiences and the process of exploration play a vital role in shaping brain development and lifelong learning. In March 2020, population-wide restrictions were imposed due to the COVID-19 pandemic. It remains to be determined whether having been raised under the global stress and restrictions of COVID-19 has influenced children’s development as they enter formal schooling. The aim of this study was to examine the extent to which having more than 50% of one’s first year of life and/or prenatal period in the COVID-19 era influences the developmental trajectory in preschool. The study compared 3-to 5-year-old children born before the pandemic (n = 63) with those who were five months or younger at its onset (n = 40). Variables assessed included executive function skills, vocabulary, and common developmental domains. Using the BRIEF-P as a standardized measure of executive function, the results demonstrate that, the pandem-ic-born cohort exhibit greater impairments than those born before the pandemic. There was also a significant increase in reports of speech and language therapy enrollment; frequent ear infections; diagnoses of hearing, speech, or language impairments; and delays in reaching developmental milestones. The pandemic-born cohort additionally reported delays in fine motor skills compared to the pre-pandemic cohort. The present study underscores the urgent need for additional resources to better support children in this cohort as they begin formal schooling.

Not 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.
