Individual and Sociolinguistic Differences in Language Background Predict Stroop Performance.

To examine how differences in language experience and sociolinguistic context impact cognitive control, 146 Spanish-English bilingual participants were tested on a non-linguistic Stroop arrows task. Dimensions of language experience included a continuum of L2 proficiency, exposure, age of L2 acquisition, and English receptive vocabulary, along with cognitive non-verbal reasoning. Sociolinguistic context varied with more exposure to Spanish for participants in Southern California (SoCal) than in the Midwest.

Language dominance predicts cognate effects and metalinguistic awareness in preschool bilinguals.

The current work investigates whether language dominance predicts transfer of skills across cognitive-linguistic levels from the native language (Spanish) to the second language (English) in bilingual preschoolers. Sensitivity to cognates ( in English/Spanish) and metalinguistic awareness (MLA) have both been shown to transfer from the dominant to the nondominant language. Examining these types of transfer together using a continuous measure of language dominance may allow us to better understand the effect of the home language in children learning a majority language in preschool.
