Korean children adopted by French families - 3y to 10y
investigate effects of early bilingualism & later language attrition
Studies of foreign adoptees - Pallier at al 2003 - findings
despite being exposed to Korean early in life - showed lower proficiency in Korean as grew older
= especially grammatical aspects
suggests early exposure may not prevent later language attrition
highlighting importance of ongoing language maintenance efforts for bilingual individuals.
Studies of foreign adoptees - Bowers at al 2009
study effects of early language exposure on later language processing
adults exposed to Zulu or Hindu in childhood
no explicit knowledge in adulthood
Training on perception of phonemic distinctions - distinctions specific to Zulu/ Hindu
Studies of foreign adoptees - Bowers at al 2009
only adults with prior language exposure showed significant improvements retaining - discriminate phonetic sounds in adulthood
early exposure may lead to long-lasting effects on language processing
= continued debate between crystallisation & interference hypothesis
Experimental evidence against RHM - De Groot & Poot, 1997
investigated forward & backward translation processes in bilingual individuals
less fluent bilinguals = faster at forward translation (1st to 2nd) compared to backward translation (2nd to 1st)
finding = contradicted predictions of RevisedHierarchical Model = suggests translation processes not always follow hierarchical pattern proposed by RHM
