1 INTRODUCTION An increasing number of studies report that cognitive and behavioral deficits in neurodevelopmental and psychiatric disorders correlate with subtle structural changes in the corpus callosum (CC), including autism (Gilmore et al., 2007; Pujol et al., 1993), schizophrenia (Chura et al., 2010; Giedd et al., 1996; Matsuzawa, 2001), and attention-deficit disorder (Giedd et al., 1994).

ABSTRACT Objective To characterize cognitive function in young children under 3 years of age over the past decade, and test whether children exhibit different cognitive development profiles through the COVID-19 pandemic. Study Design Neurocognitive data (Mullen Scales of Early Learning, MSEL) were drawn from 700 healthy and neurotypically developing children between 2011 to 2021 without reported positive tests or clinical diagnosis of SARS-CoV-2 infection.
