The pivotal hypothesis in the Pierce, Genesee, Delcenserie, and Morgan article is that phonological memory is key to clarifying the relationship between early language experience (more specifically, less and more optimal ends of the language-experience continuum) and language learning outcomes. One piece of evidence proposed is that phonological memory abilities are increased by bilingualism, with bilingualism representing enriched experience. This paper presents that data from bilingual children may contradict Pierce et al.’s central hypothesis, rather than support it.
