Màster de Lingüística Aplicada i Adquisició de Llengües en Contextos Multilingües, Departament de Filologia Anglesa i Alemanya, Universitat de Barcelona, Any: 2012, Tutora: Carmen MuñozThis case study of two multilingual boys (aged 6-7) has two aims. Firstly, it explores how the participants view their language proficiency, language dominance and language
preference and investigates how their statements show evidence of metalinguistic
awareness. Naturalistic data, semi-structured interviews and background questionnaires
were used to collect comprehensive data. The second aim is to compare participants'
statements about their own language proficiency and dominance with data from an oral narrative task in order to investigate whether they accurately predicted their dominant
language. The participants performed the task in three languages (English, Spanish and
Catalan) and their fluency and lexical richness was analyzed. Overall, fluency measures
matched with their perceptions. However, lexical richness results (as measured by
Guiraud's Index and lexical density) were inconclusive. In summation, the participants
demonstrate that young multilingual children are capable of providing accurate
information on their language proficiency from very early on. The dissertation ends with directions for future research
