Under normal circumstances, acquiring a first language, compared to acquiring a second or third language, seems to come naturally and successfully. This natural process of first language acquisition (henceforth L1A) appears to be illogical. This is because what first language learners (henceforth L1ers) attain (i.e. a grammar of adult native speakers of a given language) goes beyond the positiv...

Fluency in a second language (L2) involves a quintessentially cognitive processing system that operates quickly and effectively. The perceived importance of researching fluency through a psycholinguistic lens has motivated the related L2 research to resort to current cognitive speaking-specific models. This study, drawing on Levelt’s (1999a) psycholinguistic model, probed the deficiency sources...

This article had two aims: to provide a thorough review of the existing literature examining overall degree of foreign accent in a second language (L2), and to present a new foreign accent experiment. The literature review suggested that a wide variety of variables in#uence degree of foreign accent. These variables include age of L2 learning, length of residence in an L2-speaking country, gende...

The carbohydrate epitope L2/HNK-1 (hereafter designated L2) is expressed in the adult mouse by myelinating Schwann cells of ventral roots and muscle nerves, but rarely by those of dorsal roots or cutaneous nerves. Since substrate-coated L2 glycolipids promote outgrowth of cultured motor but not sensory neurons, L2 may thus influence the preferential reinnervation of muscle nerves by regeneratin...

Teachers can influence the complex process of learning in education, in general, and in second/foreign language (L2) learning in particular. In this light, understanding the factors influencing teachers’ pedagogical success can help L2 teachers achieve more effective teaching. This study then investigated the role of spiritual intelligence (SI) in L2 teachers’ pedagogical success. In so doing, ...

In this paper, after applying Response Surface Methodology (RSM) for Robust Parameter Design, we take into account two equations representing the mean and variance responses. Then, the control factors are determined such that these two objective functions are close to their ideal values. In this regard, the Lp method is used and its sensitivity analysis is accomplished through a numerical examp...
