“…In the United States, monolingual and bilingual speakers of English tend to differ along a range of dimensions that could affect masked speech recognition, including linguistic knowledge and access to educational resources (Calvo & Bialystok, 2014;Schneider, Martinez, & Owens, 2006). One of the most studied factors is the age at which the test language was acquired (Meador et al, 2000;Neave-DiToro, Rubinstein, & Neuman, 2017;Shi, 2010Shi, , 2014Weiss & Dempsey, 2008).
