We addressed this issue by using a propensity-score matching procedure that enabled us to match early and late bilinguals on 18 confounding variables-for example, demographic characteristics, immigration status, fitness, extracurricular training, motivation, and emotionality-that have been shown to influence cognitive control. Before early and late bilinguals were matched (N = 196), we found early active bilingual advantages in flanker effects (in accuracy), global accuracy, and sensitivity (d') on the Attention Network Test for Interaction and Vigilance and …
