A bilingual speaker is a person who speaks more than one language. A person can acquire this talent two different ways. Simultaneous bilingualism is when a person learns two languages at the same tie during childhood. Sequential Bilingualism is when the person learns a second language after they have learned their first language or native tongue. More than half of the people around he world are at least somewhat bilingual (Matlin,341). 

     Simultaneous bilingualism is more common in households where parents speak in two different languages with their child from birth, or when the child is introduced to the second language by age three (Lowry, 2011). One of the benefits of learning two languages at the same time is that simultaneous bilinguals tend to master their languages with native fluency easier than those individuals that learn a second language later on in life. This is not to say that achieving native fluency is impossible for an adult learning a second language. Studies have proven that there is no critical period for second language acquisition.  However, there does tend to be a gradual decline in second language skills as the age of acquisition gets higher. This just means that an adult learning a second language may have to work a little harder to obtain the native accent (Matlin, 346). Sequential bilingualism typically occurs as a result of education or relocation. Many people speak in one language with their parents and family members until they enter school where they learn the majority language spoken in that region. Also many students around the world are encouraged to take a foreign language in school and they can become bilingual or even multilingual in that way as well.  Others learn their second language after moving to another country for occupational reasons (Lowry, 2011). Whatever the reason may be for learning a second language, there are cognitive benefits and certain disadvantages associated with doing so.
