Early conceptions of aptitude were concerned with explicit learning abilities in formal learning settings, which according to MLAT (Modern Language Aptitude Test) were measurable based on a phonemic coding ability, an inductive learning ability, an associative memory, and a grammatical sensitivity (Carroll, 1962). However, recent understanding on…

"Second Language Acquisition -- Learning Theories and Recent Approaches" will aim to present the process of learning an additional language apart from one's native language. The process of understanding, writing, and speaking another language with fluency involves complex intellectual and emotional responses as well as continuous…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

The present study investigated a group of cognitive individual differences considered advantageous in second language learning and their role in language learning under implicit and explicit feedback conditions using both language awareness and language development measures. The study further investigated whether different types of awareness are…

In this study, we examine explicit information and aptitude within processing instruction. Forty-six learners of German in their third semester of study were divided into two groups: those who received explicit information prior to treatment (+EI) and those who did not (-EI). Participants also took the grammatical sensitivity portion of the Modern…

Due to their unique profile as childhood bilinguals whose first language (L1) became weaker than their second language (L2), heritage speakers can shed light on three key issues in bilingualism--timing, input, and cross-linguistic interaction. The heritage speakers of focus in this dissertation are Korean second generation immigrants mainly…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…

This paper reports replications of studies of implicit artificial grammar (AG) learning and explicit series-solution learning with experienced second language learners in order to examine their population and content generalizability. As found by Reber, Walkenfeld, and Hernstadt (1991), there was significantly greater variance in explicit compared…

This book examines different theoretical perspectives on the role that interaction plays in second language acquisition. The principle perspectives are those provided by the Interaction Hypothesis, Socio-Cultural Theory, and the Levels of Processing Model. Interaction is defined broadly; it is seen as involving both intermental and intramental…

Methods and approaches used at the U.S. Army Research Institute to investigate intelligent computer-assisted foreign language instruction are discussed. The research described explores the use of hypertext and natural language processing for improving language training by articulating student knowledge structures and for providing, incidentally, a…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 32 titles deal with a variety of topics, including the following: (1) textual relations within the written and spoken modes; (2) the construction of stance in conflict narrative; (3) the relational base theory of phrase…

Articles in this book on early second language learning are presented in 13 categories, with each category containing 4 to 7 papers. The categories include the following: the advantages and disadvantages of FLES (elementary school foreign language programs), FLEX (foreign language exploratory programs), and immersion program models; at what age an…
