This paper puts forward a research agenda in the area of explicit and implicit knowledge and learning of second or additional languages. Based on a brief overview of reliable findings as well as open questions in the field, three agenda items are highlighted. First, valid and reliable measures of explicit and, in particular, implicit knowledge and…

This paper evaluates the multistage adaptive test (MST) design of a large-scale academic language assessment (ACCESS) for Grades 1-12, with an aim to simplify the current MST design, using both operational and simulated test data. Study 1 explored the operational population data (1,456,287 test-takers) of the listening and reading tests of MST…

Cross-linguistically, statements and questions broadly differ in syntactic organization. To learn the syntactic properties of each sentence type, learners might first rely on non-syntactic information. This paper analyzed prosodic differences between infant-directed "wh"-questions and statements to determine what kinds of cues might be…

In Lebanese Arabic, lexical subjects may occur before or after verbs, but only before non-verbal predicates. Analysis of spontaneous language samples from 19 two-year-old children shows that postverbal (VS) and preverbal (SV) subjects emerge simultaneously. The youngest children displayed no VS-SV difference in frequency. A slight preference for…

This study explored responsive and linguistic parent input features during parent-child interactions and investigated how four input categories related to children's production of diverse, simple sentences. Of primary interest was parent use of responsive, simple declarative input sentences. Responsive and linguistic features of parent input to 20…

Indirect answers are a common type of non-literal language that do not provide an explicit "yes" or "no" to a question (e.g., "I have to work late" indirectly answered "Are you going to the party?" with a negative response). In the current study, we examined the developmental trajectory of comprehension of…

This study investigated receptive and expressive language outcomes in children with autism spectrum disorder (ASD) with and without a history of language/communication regression, employing three progressively less stringent definitions of regression. Data were derived from a large, longitudinal sample of children with ASD in which regression was…

In acquiring a native language, the input children receive, to an unneglectable extent, shapes the rate of acquisition and the ultimate achievement. This in turn has cascading effects on many aspects of later development, including but not limited to language. Providing optimal input for early language development, therefore, is of major interest…

Poor metaphor comprehension was considered a hallmark of autism spectrum disorder (ASD), but recent research has questioned the extent and the sources of these difficulties. In this cross-sectional study, we compared metaphor comprehension in individuals with ASD (N = 29) and individuals with typical development (TD; N = 31), and investigated the…

The number of conceptually bilingual daycare centers has been steadily increasing in Switzerland, a traditionally multilingual country. Yet, the focus on the languages introduced in these institutions has largely remained on one national language -- and English. We look at how English and -- in our case -- German are employed in daycare centers…

In spite of their pivotal role in language learning, psychological variables involved in language learning have received less attention in empirical research. Therefore, this paper tried to inspect the effects of interventionist DA, interactionist DA, and non-DA on EFL students' SAF, FLCA, and FLLM. To achieve this goal, 78 respondents were chosen…

This investigation reveals gender specificity in the vocabulary segment of the Kazakh language picture of the world. The study draws the material from the Explanatory Dictionary of the Kazakh Literary Language and the Kazakh Dictionary and is based on the theory of conceptual metaphor and analysis of gender-marked metaphors. The results show that…

Despite substantial scholarship relating to word structure (Anderson, 2018), for English affixes the relationship between productivity, genre, and second language (L2) learning remains unclear. Analysis of the existing literature reveals that deadjectival noun suffixes (i.e., nouns derived from adjectives such as "appropriacy" or…

With the increase in linguistic and cultural diversity in South Korea, the landscape of English education in Korean classrooms has been changing. This has led to an increased need to explore the language and literacy practices of the emergent multilingual youth in Korea where one (official) language (Korean) has been predominantly used as the…

This state-of-the-art review focuses on translanguaging in education. In recent years, scholars have engaged in the conceptualisation of 'translanguaging' (e.g. García, 2009; García & Wei, 2014a; Wei, 2018) as well as in conducting a vast and ever-increasing number of empirical studies, in educational contexts in particular. This article aims…
