A Longitudinal Study on Bidirectional Relations between Executive Functions and English Word-Level Reading in Chinese American Children in Immigrant Families.

Abstract This two-wave (1.5 years apart) longitudinal study examined the bidirectional relations between measures of executive function (EF; working memory, attention focusing, inhibitory control, and a comprehensive EF measure) and two types of English word-level reading (pseudoword reading and word reading) among 258 school-aged children (52.6% boys, age = 5.8–9.1 years, in 1st to 3rd grades at Wave 1) from Chinese American immigrant families. Cross-lagged panel analyses were conducted to test whether the four EF measures and English word-level reading proficiency predicted one another controlling for prior levels of EF or reading, as well as demographic characteristics and children's English and Chinese language proficiency. We found a positive bidirectional association between the comprehensive EF measure and pseudoword reading. By contrast, although the comprehensive EF measure positively predicted word reading over time, word reading did not predict comprehensive EF. Additionally, both word reading and pseudoword reading positively predicted working memory over time. The results provided partial evidence that English word-level reading is bidirectionally related to EF among early elementary school-age dual language learners.
