Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

Despite the extensive research on bilingual development, our understanding of how lexical competition unfolds in the bilingual mind remains limited. Previous studies have predominantly focused on crosslinguistic competition, neglecting the examination of the competition process within each language and the influence of diverse bilingual…

While much research has examined second language (L2) phonetic acquisition, less research has examined first language (L1) attrition in terms of the voice onset time (VOT) of voiceless stops. The current study examined L2 acquisition and L1 attrition in the VOT of word-initial voiceless stops among late English-Arabic and Arabic-English bilinguals…

This longitudinal study examined the development of narrative micro- and macrostructure in Japanese-English bilingual returnee children. Returnees are children of immigrant families who move to a foreign country, spending a significant portion of their formative developmental years in the foreign majority language context before returning to their…

This article reports on the findings of an empirical study that relates translation studies and research on language acquisition/attrition by looking at the interpretation of overt pronominal subjects, previously found to be problematic in both domains. The focus is on the resolution of intra-sentential anaphora and cataphora in Italian by two…

The present article examines the relationship between age and dominance in bilingual populations. Age in bilingualism is understood as the point in development at which second language (L2) acquisition begins and as the chronological age of users of two languages. Age of acquisition (AoA) is a factor in determining which of a bilingual's two…

This study analyzed how six Heritage language learners at the university level gained conscious awareness and control of the concept of modality as revealed in student verbalizations (Vygotsky, 1998) throughout five different written communicative events. This work took place in the only course designed for Heritage language learners at a large…

This study investigates the effects of weekly heritage language (HL) classes on first language (L1) proficiency in speakers who arrived in the second language (L2)-dominant setting before the onset of puberty. Two groups of L1 Spanish--L2 Swedish bilingual high school students living in Sweden participated in the study. One group currently…

This study examines the potential native language (L1) attrition of the ongoing value of the Spanish present tense among long-term Spanish immigrants. Based on the assumption of second-language (L2) transfer and proposals on the permeability of interface-conditioned structures, it is hypothesized that long-term Spanish immigrants will show…

Bilinguals must focus their attention to control competing languages. In bilingual aphasia, damage to the fronto-subcortical loop may lead to pathological language switching and mixing and the attrition of the more automatic language (usually L1). We present the case of JZ, a bilingual Basque-Spanish 53-year-old man who, after haematoma in the…

Change of first language (L1) status from the most stable language to a less accessible language over the life-span of a bilingual individual is termed "language attrition". Such a shift in ease of L1 access has been reported to affect the lexicon (Pelc, 2001) more than other aspects of language. However, whether L1 attrition is affected by…
