Further Research
There is currently no differentiation of normal and deviant bilingual development.
Further study into the effects of changing a child’s linguistic environment could uncover the minimal language input required to maintain "active use potential" in a particular language.
Simultaneous trilingualism is also possible. There is significantly less research in this area than in simultaneous bilingualism. However, trilingual language acquisition in young children has been shown to generally mirror bilingual acquisition.

Famous quotes containing the word research:
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is “What does a woman want?” [Was will das Weib?]”
—Sigmund Freud (1856–1939)
“The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of “justice” or absolute “right and wrong,” while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?”
—Ron Taffel (20th century)
