Abstract | Reports of the bilingual advantage on executive control are inconsistent particularly in young
participants. One reason may be the lack of precision regarding measurement of cognitive
processes underlying the bilingual advantage. The present study compared the performance
on the Flanker task of 29 young monolinguals (mean age = 18.69) and 30 young bilinguals
(mean age = 20). Following the methodology reported by Ong, Sewell, Weekes, McKague
and Abutalebi (2016) with bilingual seniors, Flanker performance was analyzed using the
diffusion model (Ratcliff, 1978), which assumes decision-making process is a stochastic
evidence accumulation process composed of empirically validated psychological parameters
including drift rate and non-decision time. Results showed a bilingual advantage for young
adults in drift rate suggesting differences in speed of evidence accumulation during decision
processes, with no differences in other parameters. The conclusion is that young bilinguals
evidence an advantage in conflict monitoring most likely due to their bilingual experience.
