Objectives: The study aimed to investigate the predictive potential of language environment and vocal development status measures obtained through integrated analysis of Language ENvironment Analysis (LENA) recordings during the prelinguistic stage for subsequent speech and language development in Korean-acquiring children. Specifically, this…

Background: Children with phonological impairment present with pattern-based errors in their speech production. While some children have difficulties with speech perception and/or the establishment of robust underlying phonological representations, the nature of phonological impairment in children is still not well understood. Given that…

Second language (L2) grammar learning is difficult. Two frameworks--the psycholinguistic lexical bottleneck hypothesis and the neurocognitive declarative/procedural model--predict that faster L2 lexical processing should facilitate L2 incidental grammar learning. We tested these predictions in a pretest-posttest syntactic adaptation study of…

In many domains, learners extract recurring units from continuous sequences. For example, in unknown languages, fluent speech is perceived as a continuous signal. Learners need to extract the underlying words from this continuous signal and then memorize them. One prominent candidate mechanism is statistical learning, whereby learners track how…

Recent studies have suggested that language aptitude is a domain-general and flexible trait to acquire foreign languages, regarding various cognitive abilities such as memory systems as its crucial components. Despite a growing interest in working memory, however, much remains unknown about the impact of associative memory on language aptitude.…

Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed…

The current study reported an empirical investigation that tested the collective and individual effects of morphological awareness and cognate awareness on Japanese word learning among Chinese learners of Japanese. 131 Chinese learners of Japanese participated in this study. They completed morphological awareness measurements (morpheme…

Second language (L2) enjoyment has gained recent interest, but little research has attended to the sources of L2 vocabulary learning enjoyment. Drawing on the regulatory focus theory and the assumption that advancing toward a goal can contribute greatly to learning enjoyment, this study examined the extent L2 vocabulary selves and capacity for…

While it has been shown that socioeconomic status (SES) is important for children's literacy development in their first language (L1), less is known about its association with reading in a second language (L2). The present study examined the different effects of SES on the acquisition of reading in Chinese as L1 and English as L2 from ages 7 to…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

We test children's distributive and collective sentence interpretations and the variables that predict them. In our first experiment, we establish that adult English collective sentences with "the" or "some" in the subject are categorically collective in their interpretations. We further demonstrate that children's collective…

Vocabulary knowledge strongly predicts second language reading, listening, writing, and speaking. Yet, few tests have been developed to assess vocabulary knowledge in French. The primary aim of this pilot study was to design and initially validate the Context-Aligned Two Thousand Test (CA-TTT), following open research practices. The CA-TTT is a…

Very few studies have investigated second language (L2) knowledge of word parts. The present study was set to measure L2 recognition of 35 English prefixes and the factors that might predict scores. The form and meaning sections of Sasao and Webb's Word Part Levels Test were administered to 152 Arabic learners of English as a foreign language…

Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and…

Second language (L2) speakers often experience difficulties in learning words with L2-specific phonemes due to the unfaithful lexical encoding predicted by the fuzzy lexical representations hypothesis. Currently, there is limited understanding of how allophonic variation in the first language (L1) influences L2 phonological and lexical encoding.…
