Effects of SES on Executive Attention in Malay–English bilingual children in Singapore

Abstract

Thirty-four 4 to 6-year-old Malay–English bilinguals (both balanced and dominant) characterized as low SES on income and parental education were tested on the child-Attentional Network Task (ANT) (Rueda, Rothbart, McCandliss, Saccomanno & Posner, 2004) measuring executive attention. Although SES measures fell below the Singapore median, Malay children's performance on the child-ANT remained high when compared to other age-matched monolingual and bilingual children previously tested with the child-ANT (Yang, Yang & Lust, 2011), and Chinese–English Singaporean bilinguals (Yang, Yang & Kang, 2014). None of the three SES measures – father's and mother's education, and income – significantly correlated with child-ANT components. Regression analyses confirmed that none of the SES measures significantly predicted performance on the child-ANT. Both balanced and dominant bilinguals displayed high executive control. We consider the possibility that cultural variations, (e.g., simultaneous and pervasiveness of bilingualism in Singapore, or pervasive code-switching), may ameliorate potential negative effects of SES on executive control development.
