This study is the first attempt to explore the relationship between rater variables focusing on raters' language aptitude and their judgments of second language (L2) speech. Thirty-four English listeners rated 65 spontaneous native and nonnative speech samples for comprehensibility, accentedness, and fluency. They also completed the LLAMA language…

A subtest of the LLAMA test battery (LLAMA_D) has been proposed as a potential test of implicit learning aptitude. To improve its construct validity, in the present study, the original LLAMA_D (a) instructions for incidental learning were modified, and (b) confidence ratings of test responses and (c) reaction time (RT) measurements were added.…

We closely replicated Wu and Ortega (2013), who found that an elicited imitation test (EIT) reliably distinguished low-level from high-level language abilities among instructed second language (L2) learners of Mandarin Chinese. The original study sampled learners: (1) from second-level courses to represent low-level language abilities; and (2)…

While an elicited imitation test (EIT) has been widely used as a measure of oral proficiency in second language acquisition (SLA) research, it is still unclear the extent to which memory capacity impacts EIT performance. In light of this gap, the present study sought to clarify the nature of elicited imitation by examining the relative…

This study investigated the effects of task complexity on child learners' second language (L2) gains, the relationship between aptitude and L2 development, and the extent to which task complexity influences this relationship when recasts are provided. Sixty child EFL learners were assigned to two experimental groups. During the treatment, one…

This study investigates the relationship between foreign language aptitude and the learning of two English structures defined as easy or difficult to learn. Using a quasiexperimental design, 66 secondary-level learners of English as a foreign language from three intact classes were provided with four hours of instruction on the "passive"…

This quantitative study focuses on the relationship between foreign language learners' aptitude and proficiency test scores. Four groups of 136 beginning students received six months of Initial Acquisition Training (IAT) in four different language categories, according to the level of complexity for an English speaker: French (Category I),…

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…

A large body studies into individual differences in second language learning has shown that success in second language learning is strongly affected by a set of relevant learner characteristics ranging from the age of onset to motivation, aptitude, and personality. Most studies have concentrated on a limited number of learner characteristics and…

The Pueblo People of the Southwest face numerous challenges with reference to language issues. A substantial number of Native American students are placed into special education possibly due to different linguistic abilities. The over-identification of Native American students for special education programs may be due to the lack of knowledge as a…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

In this study I examine the construct of aptitude in learning Chinese as a second language (L2) to an advanced level. I test 2 hypotheses: first, that L2 aptitude comprises 4 components--working memory, rote memory, grammatical sensitivity, and phonemic coding ability--and second, that L2 aptitude affects learning both directly and indirectly…

The purpose of this dissertation was to examine the relationships between working memory (WM) and three commonly used learning strategies or conditions in the nature of proficiency among adult L2 Russian learners. Based on the aptitude-learning condition interaction framework articulated by Robinson (2002b), the study identifies two types of…

Thirteen children and young adults with Down syndrome (DS) completed tests of language and reading and their performance was compared to that of three control groups. Reading comprehension was confirmed to be a specific deficit in DS and found to be strongly correlated with underlying language skills. Although reading comprehension was more…

This inquiry analyzed the relationships between individual differences and gains made in oral proficiency of adult, second language learners of Spanish during one semester studying abroad. Oral proficiency was measured using a pre/post-SA Computerized Oral Proficiency Instrument (COPI, CAL, 2009). Gain scores were correlated with two cognitive…
