There has been increasing L3 research on L3 transfer selectivity, especially concerning which factor triggers crosslinguistic influence during L3 acquisition. According to Slabakova's (2016) Scalpel Model, every linguistic property has distinct and unique input factors regarding L3 acquisition such as high/low frequency or positive/negative input.…

Much empirical research on textbook analysis has been undertaken. However, little evidence with regard to the adoption of SLA findings in the textbook analysis was reported, particularly for the Indonesian EFL textbooks. To fill this void, this study aimed at analyzing a textbook endorsed by the Indonesian Ministry of Education and Culture,…

The current study investigates second language acquisition of Chinese object ellipsis to probe the development of features transferred from learners' native language without robust confirming or disconfirming evidence in the second language (L2) input. It is argued that Chinese allows object ellipsis licensed by a verb with a [VCase] feature but…

Languages exhibit variation at all linguistic levels, from phonology, to the lexicon, to syntax. Importantly, that variation tends to be (at least partially) conditioned on some aspect of the social or linguistic context. When variation is unconditioned, language learners regularize it -- removing some or all variants, or conditioning variant use…

The aim of the paper is to present the results of a research project called 'Tell Me', conducted from October 2018 to March 2020. The project focused on Bengali children living in Venice, Italy, and aimed to describe (1) children's languages in the home environment and at school; (2) the quality and quantity of input they receive in every language…

The impact of the lexicons that were often used in the past will be eroded due to the environmental conditions that surround them. This study has examined the critical condition in Balinese lexicon extinction. There are some Balinese language vocabularies that are almost extinct by the current generation due to cultural hegomonization. The…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

The 'root infinitive' phenomenon in child speech is known from major languages such as Dutch. In this case study, a child acquiring the Papuan language Nungon in a remote village setting in Papua New Guinea uses two different non-finite verb forms as predicates of main clauses ('root' contexts) between ages 2;3 and 3;3. The first root non-finite…

This study examines the "ba" and "bei" constructions in Mandarin using data from the Tong corpus, a new multimedia longitudinal child language corpus. A unified aspectual account of the two constructions is proposed: both require telic predicates, and should thus correlate with the perfective rather than imperfective aspect for…

From the current available research, it is evident that further evidence is needed to understand Second Language Acquisition (SLA) processes under planned bilingualism approaches in English as a Second Language (ESL) environments. This study employs an explanatory single case strategy to investigate the oral proficiency and SLA experiences of a…

Immersion programs have long been considered the gold standard for school-based language revitalization, but surprisingly little attention has been paid to the quantity and quality of the input that they provide to young language learners. Drawing on new data from three such programs (Kaqchikel, Western Subanon, and Maori), each with its own…

This article focuses on the acquisition of mood in early complement clauses of European Portuguese (EP). Two semantic features are involved in the EP mood system--epistemicity and veridicality. An elicited production task administered to 80 children aged 4 to 9 showed that, even though children use the subjunctive in [-- epistemic] contexts, the…

While previous sociolinguistic research has demonstrated that children faithfully acquire probabilistic input constrained by sociolinguistic and linguistic factors (e.g., gender and socioeconomic status), research suggests children regularize inconsistent input-probabilistic input that is not sociolinguistically constrained (e.g., Hudson Kam &…

This study investigates the interpretation of disjunction words (English or) in negative sentences by Turkish- and German-speaking children. Both children and adults were asked to judge Turkish/German sentences corresponding to the English sentence "This animal did not eat the carrot or the pepper." Children acquiring both languages…

The interaction between input frequency and constructional interference receives little attention in second language (L2) research. Two studies were conducted to test the effect of this interaction. Study 1 examined effects of both Zipfian frequency (ZF) and balanced frequency (BF) on L2 learning of English subject-extracted relative clauses…
