This study investigates the effect of learning environment (study abroad vs. at home) on the pragmatic development of Chinese speakers’ L2 English refusals. A total of 20 Chinese Study Abroad (SA) students participated in the study and their L2 refusals were examined over the course of one academic year. These refusals were compared with those of 20 Chinese At Home (AH) students. Data were coll...

Research on spoken language bilinguals has shown that there is a significant relationship between socioeconomic status (SES) and literacy outcomes. The mechanism of SES as a predictor of literacy success has two competing explanations. One assumes a direct impact of SES on literacy through expanded opportunities to read and better maternal mediation of literacy activities; the other assumes an ...

to enrich our understanding of the attitudinal/motivational basis of foreign language learning at junior high school level, this study investigated the students’ status of l2 motivation, the relationship between motivational factors, and the possibility of predicting their motivated learning behavior in light of dörnyei’s (2005, 2009) theory of l2 motivational self system. to this end, 1462 jun...

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and effects complexity on their performance. 92 learners English in three intact classes were assigned to tasks different (simple, +complex, ++complex). In response errors use present third person singular verb forms, participants received recasts. L2 de...

Visual and somatosensory cortices exhibit profound experience-dependent plasticity during development and adulthood and are common model systems for probing the synaptic and molecular mechanisms of plasticity. However, comparisons between the two areas may be confounded by a lack of accurate information on their relative rates of development. In this study, we used whole-cell recording in acute...

In L2 development, the cognitive complexity of tasks plays a crucial role in task performance and language features produced. However, there have only been few studies addressing the impact of task complexity on EFL learners' attention to L2 system and form-focused self-repairs (FFS).This study explores the role of increasing cognitive task complexity in EFL learners' form-focused attention (FF...

The study of second language acquisition (SLA) is often hindered by substantial variability in the background of learners, their learning process and the input they receive. This diversity often makes it difficult to isolate specific learning factors and study their impact on L2 development. We present a computational study of SLA as an alternative methodological approach. By applying a usage-b...

Steroidogenic factor 1 (SF1; Ad4BP/NR5A1) plays key roles in gonadal development. Initially, the Sf1 gene is expressed in mouse fetal gonads of both sexes, but later is up-regulated in testes and down-regulated in ovaries. While Sf1 expression is activated and maintained by Wilms tumor 1 (WT1) and LIM homeobox 9 (LHX9), the mechanism of sex-specific regulation remains unclear. We hypothesized t...

SUMMARY Increasing evidence suggests that patients with L2-HGA have a predisposition to cerebral neoplasms. This may be related to the pathologic accumulation of L2-HG because high amounts of 2-HG have been found in brain neoplasms that have IDH1 mutations. Our experience, on the basis of 11 previously unreported cases of L2-HGA, 3 of which developed cerebral neoplasms during the course of the ...
