Executive Function Mediates the Association between Toddler NegativeAffectivity and Early Academic Achievement

摘要

Research FindingsWe examined the nature of association between toddler negative affectivity (NA) and later academic achievement by testing early childhood executive function (EF) as a mediator that links children’s temperament and their performance on standardized math and reading assessments. One hundred eighty-four children (93 boys, 91 girls) participated in our longitudinal study. Children’s NA was measured at age 2 and EF at age 4. At age 6, academic achievement in reading and mathematics were assessed using the Woodcock Johnson III Tests of Achievement (href="#R71" rid="R71" class=" bibr popnode">Woodcock, McGrew, & Mather, 2001). Results indicated that NA at age 2 negatively predicted EF at age 4, which positively predicted mathematics achievement and reading achievement at age 6. Age 4 EF mediated the relation between age 2 NA and age 6 academic achievement on both reading and math. These findings highlight the significance of considering both NA and EF in conversations about children’s academic achievement.
