ABSTRACT The change in the educational model derived from the COVID-19 pandemic might have an impact on cognitive development, particularly on Executive Functions (EFs). The aim of this study was to explore cognitive performance in adolescents at two time points (12 and 14 years of age), before and after the pandemic restrictions. We also analyzed possible sex differences in the results. We evaluated EFs using the Neuropsychological Battery of Executive Functions and Frontal Lobes (BANFE-2), which includes four cognitive indices corresponding to specific cognitive functions and associated prefrontal areas: Orbitofrontal Cortex (OC index -OCI-), Anterior Prefrontal Cortex (APCI), Dorsolateral Prefrontal Cortex (DCI), and Prefrontal cortex as an index of global EFs (EFI). The ANOVA conducted to compare the evaluations before and after the pandemic revealed no significant pre-post-pandemic differences in any sex and in any BANFE-2 index, except for the OCI, in which post-pandemic performance was impaired in boys (pre and post mean score = 96.61 vs. 66.53), but not in girls (pre and post mean score = 93.55 vs. 95.0). Our findings are thus compatible with the idea of a different vulnerability to change in the educational model between sexes, and they also reveal which specific EFs may have been affected during the pandemic.
