Cognition and Language
Although the controversial issue of bilingual education versus immersion has
strong
political undercurrents, evidence shows that the ability to speak two languages
provides signifi cant cognitive benefi ts over speaking only one language. For example,
bilingual speakers show more cognitive fl exibility and may understand concepts more
easily than those who speak only one language. They have
more linguistic tools for
thinking because of their multiple-language abilities. In turn, this makes them more
creative and fl exible in solving problems (Heyman & Diesendruck, 2002; Bialystok &
Martin, 2004; Kuo, 2007).
Furthermore, speaking several languages changes the organization of the brain.
For example, bilingual speakers who learn their second language as adults show
different areas of brain activation compared with those
who learn their second
language in childhood. In addition, brain scans show that people who speak multiple
languages have distinct patterns of brain activity according to the language that they
are using (see Figure 2) (Kim et al., 1997; Kovelman, Baker, & Petitto, 2008; Kovacs &
Mehler, 2009).
Related to questions about bilingual
education is the matter of biculturalism, that is,
being a member of two cultures and its psychological impact. Some psychologists
argue that society should promote an
alternation model of bicultural competence. Such
a model supports members of a culture in their efforts to maintain their original
cultural identity as well as in their integration into the adopted culture.
In this view, a
person can belong to two cultures and have two cultural identities without having to
choose between them. Whether society will adopt the alternation model remains to be
seen (Carter, 2003; Benet-Martínez, Lee, & Leu, 2006; Tadmor, 2007).
FIGURE 1
The language of diversity. Some 22% of the people in the United States speak
a language other than English at home.
Most of them speak Spanish; the rest speak an
astounding variety of diff erent languages. Where are the largest clusters of non-English
speakers in the United States, and what do you think explains these concentrations?
