This interconnectivity of both languages in the bilingual brain can also have effects on the way concepts are represented in the bilingual mind. There is a mutual influence that seems to occur in the bilingual brain. Studies of categorization by bilinguals show that categories are simplified in the brains of bilinguals compared to monolinguals. Specifically, the corresponding category centers (examples of typical category exemplars) were closer together for bilinguals than monolinguals. Additionally, bilinguals showed a pattern of having "less complex category boundaries" (p. 270), which is where atypical exemplars would be placed, and "more similar centers of corresponding categories" (p. 288) than monolinguals. This shows the mutual influence that two languages can have on the representation of concepts in the brain.
