Relations among degree of bilingualism and bilateral information processing in children and adults
Aims and objectives:The primary goal of this study was to examine whether degree of bilingualism related to dichotic listening accuracy, a measure of bilateral processing, after controlling for age and income.Methodology:Participants included 59 children ages 6–11 years ( M = 7.86, SD = 1.81) and 61 adults (18–83 years) ( M = 34.02, SD = 15.70). Participants completed demographic surveys, vocabulary assessments in English and Spanish, and a dichotic listening test.Data and analysis:Multiple linear regressions examined whether the degree of bilingualism predicted bilateral processing.Findings:Degree of bilingualism predicted bilateral processing in the whole sample of children and adults.Originality:This study is one of the first to examine bilingualism and bilateral processing while including both children and adults. It also importantly controlled for a possible cognate facilitatory effect and participant income differences and measured bilingualism on a continuum.Significance:Results highlight the importance of including bilingual groups of different ages when researching bilingualism and laterality.
期刊介绍:
The International Journal of Bilingualism is an international forum for the dissemination of original research on the linguistic, psychological, neurological, and social issues which emerge from language contact. While stressing interdisciplinary links, the focus of the Journal is on the language behavior of the bi- and multilingual individual.
