== Acceleration and deceleration ==
The theories of acceleration and deceleration are bilingual child language acquisition theories based on the known norms of monolingual acquisition. These theories come from comparisons of bilingual children's acquisition to that of their monolingual peers of similar backgrounds.

Acceleration is a process similar to that of [[Bootstrapping (linguistics)|bootstrapping]], where a child acquiring language uses knowledge and skills from one language to aid in, and speed up their acquisition of the other language.<ref>{{Cite journal|last1=Fabiano-Smith Leah|last2=Goldstein Brian A.|date=2010-02-01|title=Phonological Acquisition in Bilingual Spanish–English Speaking Children|journal=Journal of Speech, Language, and Hearing Research|volume=53|issue=1|pages=160–178|doi=10.1044/1092-4388(2009/07-0064)|pmid=20150407}}</ref>

Deceleration is a process in which a child experiences negative effects (more mistakes and slower language learning) on their language acquisition due to interference from their other language.
