The Bilingual Advantage in Executive Functioning Hypothesis is a ground-breaking book that explores one of the liveliest debates in bilingualism and cognitive psychology. It examines the hypothesis that using two languages leads to the enhancement of domain-general executive functioning (EF) and argues that either the bilingual advantage does not exist or is restricted to very specific circumstances. The conclusion extends to situations where EF is referred to as self-control, self-regulation, self-discipline, attention-control, impulse control, inhibitory control, cognitive control, and willpower.
