Is There a Cognitive Advantage for Spanish Heritage Bilinguals? A First Look

Abstract

We report the findings from an ongoing study on the relationship between bilinguals’ language experience and cognitive control. Previous research suggests that early bilingualism exerts an advantage on executive control, possibly due to the cognitive requirements involved in the daily juggling of two languages (Adesope, Lavin, Thompson, & Ungerleider, 2010). However, other researchers also have argued against a cognitive control advantage in bilinguals (Hilchey & Klein, 2011). It remains unclear whether cognitive benefits hold true for bilinguals across different contexts, given differences in sociolinguistic and socioeducational settings that shape individual bilingualism. In the current study, following Costa, Hernández and Sebastián-Gallés (2008) who tested Catalan-Spanish bilinguals, young adult simultaneous heritage bilinguals and late classroom emerging bilinguals of Spanish in the U.S. completed three blocks of the Attentional Network Task (ANT) (Fan, McCandliss, Sommer, Raz, & Posner, 2002) to gauge executive control abilities. Results for the executive network component of the ANT reveal no significant differences between the two bilingual groups, although the descriptive data trend suggests that HL bilinguals experienced less difficulty in solving conflicting information and demonstrated fewer switching costs between trials. These first findings imply that the bilingual advantage is not replicated across contexts, and that socioeducational practices determine individual patterns of language use, which in turn leads to variation in cognitive outcomes.
