This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

Background: Vocabulary knowledge (VK) and morphological awareness (MA) are crucial linguistic variables for reading comprehension. However, the extent to which MA subskills are intertwined with different facets of VK in their contributions to reading comprehensions, and how MA influences the reading abilities of English as a foreign language (EFL)…

This study examines the intricate relationships between home language use, oral language skills (phonological awareness, morphological awareness, and receptive vocabulary), and literacy skills (word reading and spelling) in English and Chinese among young bilinguals. The sample includes 249 first-grade and 263 third-grade bilingual students in…

The present study examines the mechanisms of lexical case acquisition in Russian by two-to-five-year-old Russian monolingual (n = 54) and Russian-English bilingual children (n = 38). Participants performed a picture-based sentence completion task. Sentences were constructed to elicit production of real Russian words (n = 24) and nonce words (n =…

The positive turn in SLA (MacIntyre at al., 2016) has sparked growing interest in the relationship between positive affective variables and language learning outcomes. Foreign language enjoyment has garnered particular attention as a positive emotion supporting language learning behaviors and achievement. However, within psychology and cognition,…

Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

This study explored the use of sophisticated vocabulary, complex syntax, and decontextualized language (including book information, conceptual information, past/future experiences, and vocabulary information) in teachers' instructional interactions with children during the literacy block in prekindergarten and kindergarten classrooms. The sample…

The present study complemented the extant second language (L2) Age of Acquisition (AoA) normative database by providing over 3500 English L2 words on objective AoA and over 2600 English L2 words on subjective AoA. The correlation between the objective and subjective L2 AoA confirmed the validity of the present database. The objective L2 AoA was…

This study aimed to examine incidental learning of multiword expressions (MWEs) from bilingual captioned videos among language minority students. The participants consisted of 403 language minority university students enrolled in the Preparatory Year Programme (PYP) in the Southern part of China. The study evaluated participants' vocabulary…

Oral language comprehension (OLC) and vocabulary depth are widely recognized as key predictors of reading comprehension. However, research has either provided a limited representation of OLC or failed to acknowledge the distinctive predictive nature of vocabulary depth. This study investigates the combined contributions of OLC, conceptualized as a…

This longitudinal study investigated development of second language (L2) reading comprehension ability and predictive contributions of five L2 reading components (word recognition speed, listening comprehension, vocabulary breadth, grammar knowledge and first language [L1] reading comprehension) using latent growth curve modelling. The…

Few studies aimed to disentangle different aspects of vocabulary depth (VD) knowledge and examine their contribution to second-language (L2) reading comprehension. To fill this gap, this study distinguished between two VD aspects, that is, semantic network knowledge and polysemous knowledge; and tested how they, together with vocabulary size (VS),…

The field of vocabulary instruction has witnessed the emergence of three models that operationalize the construct of elaborate processing and thus help predict the effectiveness of vocabulary learning activities: Involvement Load Hypothesis (ILH), Involvement Load Hypothesis Plus (ILH Plus), and Technique Feature Analysis (TFA). However, no…

In second language (L2) research, the lexical unit is often defined as a base word plus inflectional and derivational forms through Level 6 of Bauer and Nation's framework (WF6). WF6 use has been justified by the assumption that once a form is known, recognition of other WF6 members requires little extra effort. A more lenient view holds that an…

To achieve efficient reading comprehension, Chinese as a second language (L2) learners adopt various component skills and knowledge, including the aspects of vocabulary, grammar, and coherence. However, there is no consensus regarding the relative predictive powers of these three areas in L2 reading comprehension. Instead of employing direct…
