Dr. Robert M. Kurtz, speech-language pathologist states the following: Growing up bilingual can be a tremendous blessing. In addition to the obvious benefit (i.e., the ability to speak and understand more than one language), recent research has revealed a number of cognitive advantages to bilingualism. Bilingual children have been shown to have:
Better metalinguistic awareness (ability to identify and describe characteristics and features of language).
Better classification skills.
Better concept formation.
Better analogical reasoning.
Better visual-spatial skills.
Better storytelling skills.
Better semantic development.
