Abstract
This study explores the locus of language selection during bilingual speech production. More specifically, it investigates whether age of acquisition has any effect on language selectivity and how competition is resolved between languages existing in the mind of a bilingual. For example, when an Urdu-English bilingual is asked to name a picture of a dog in English, at what point does his mind select English and not Urdu as the production language? Two different theories regarding language selection phenomenon are presented: Green's Inhibitory Control IC)Model 1986; 1998) and The Concept Selection Hypothesis La Heij, 2004. Costa and Santesteban 2004) have proposed that both the theories may be correct but may be dependent on proficiency
level of the bilingual. They proposed that the IC Model and the Concept Selection Hypothesis can only depict lexical processing of bilinguals with low and high proficiency levels, respectively.
