Oral and written language abilities in young Spanish/English bilinguals

Purpose: The purpose of this study was to compare oral and written language abilities in English and Spanish of young bilinguals residing in the USA. Methodology: Sixty-two participants (mean age = 23.7; SD = 3.50), consisting of 42 bilinguals (born of Spanish-speaking parents) and 20 English monolinguals, were administered a battery of 15 language tasks. Analysis: Bilinguals were divided into two groups: (a) US-born (simultaneous bilinguals who had been exposed to English and Spanish since birth and educated primarily in English) and (b) Latin American-born (early sequential bilinguals who were educated in Spanish and English, although exposed to Spanish at birth and to English before the age of 10). Findings: Higher lexical ability was demonstrated in English compared to Spanish in bilinguals. Performance in grammar tests of the two languages was inconsistent. Reading/writing ability in English was similar for participants born in the USA and in Latin America; however, participants who were born in Latin America had significantly higher scores for Spanish reading/writing tasks. When comparing performance in English tests, it was found that scores for bilingual participants were similar to those of English monolinguals. Originality: The current study directly compares oral and written language abilities in two subgroups of young Spanish/English bilinguals. Three language dimensions are studied: lexicon/grammar; oral/written language; and language knowledge/lang
