Bidirectional relationships between emotion understanding and executive functions in young children: A latent change score modeling study

Abstract

An overarching framework in the field of developmental psychology highlights the close linkage of cognition with emotion; however, the extent to which this framework supports the relationship between executive functions and emotion understanding in young children remains unclear. Hence, we employ a longitudinal tracking study to investigate the bidirectional relationship between emotion understanding and executive functions. A total of 112 children ( M = 48.01 months, 68 boys) were recruited to perform tests at three time points within 2 years. Results from our cross-lagged model analysis indicated that early executive functions significantly predicted the development of emotion understanding at Time 2 and Time 3, while emotion understanding at Time 2 significantly predicted the subsequent development of executive functions in Time 3, controlling for age, gender, and family socioeconomic status (SES). Moreover, the latent change score model analysis further revealed the developmental trends and interrelations of executive functions and emotion understanding over time. Specifically, children with higher initial level of executive functions exhibited faster growth in emotion understanding over time, and then this improved emotion understanding predicted the changes in later executive functions. Overall, these findings elucidate significant developmental progressions for how emotion understanding and executive functions interact with each other during early childhood.
