Abstract

This study investigates the relationship between emotional traits—internalizing (INT) and externalizing (EXT) subclinical characteristics—and cognitive performance in typically developing children (TDC). INT and EXT measures from the Strengths and Difficulties Questionnaire (SDQ) and cognitive task performance in various cognitive domains, including in verbal comprehension, perceptual reasoning, memory, and cognitive inhibitory control, using standardized neuropsychological test battery (NIH Toolbox, WASI) were examined. Regression analyses, ordinary least squares and robust regression models, were used to explore associations between INT and EXT traits and cognitive task performance, controlling demographic factors such as gender, socioeconomic status (SES), and ethnicity. Results indicate INT and EXT traits, independently or in combination, relate to distinct cognitive profiles, with INT traits specifically associated with lower verbal comprehension skills. Socioeconomic status emerged as a consistent positive predictor of cognitive proficiency. Results highlight the importance of emotional diversity in TDC and its potential influence on cognitive development.
