Although studies have consistently found negative correlations between second language (L2) anxiety and L2 achievement, the anxiety concept is criticized for the failure to consider confounding variables, particularly first language (L1) achievement, in the relationship between language anxiety and language achievement. Also, past studies tend to…

Despite the widespread use and effectiveness of the Modern Language Aptitude Test (MLAT) composite score in predicting individual differences in L2 achievement and proficiency, there has been little examination of MLAT subtests, although they have potential for illuminating components of L2 aptitude and the mechanism of prediction. Here we use…

Widespread use of the Modern Language Aptitude Test (MLAT) in L2 studies of individual differences implicitly assumes that L2 aptitude is a distinct cognitive facet. There is considerable evidence for prediction from L1 abilities to L2 learning. In this longitudinal study, L1-MLAT-L2 relations were examined in 307 US secondary students based on…

High school students' beliefs toward their abilities could be fixed or malleable, and mindset may differ between boys and girls. The aim of this article is three-fold: to examine the beliefs of students as to whether their abilities are fixed or malleable in the context of English language learning, to know if mindsets of boys and girls are…

In recent decades, integrated language competence has been highlighted in the language curricula taught in schools and institutions, and the relationship between test-takers' performance on integrated tasks and comprehension sources has been much studied. The current study employed the frameworks of reading and listening comprehension processes to…

Studies with U.S. secondary second language (L2) learners have revealed individual differences (IDs) in first language (L1) skills and L2 aptitude and shown that these IDs are related to L2 achievement and proficiency. In this study, U.S. students were administered measures of L1 achievement, L1 cognitive processing, and L2 aptitude; followed…

Second language (L2) educators have proposed a unique anxiety for general L2 learning and an anxiety specific to L2 reading. Since the early 1990s, the L2 anxiety concept has been challenged on theoretical and empirical grounds. In this investigation, U.S. high school L2 learners were administered the Foreign Language Reading Anxiety Scale (FLRAS)…

Authors examined the relationship between individual differences in L1 print exposure and differences in early L1 skills and later L2 aptitude, L2 proficiency, and L2 classroom achievement. Participants were administered measures of L1 word decoding, spelling, phonemic awareness, reading comprehension, receptive vocabulary, and listening…

In this article, I describe studies conducted over 25 years with secondary and post-secondary L2 learners in the United States. The evidence from these studies shows that there are important connections between students' early L1 skills and their L2 aptitude and L2 proficiency and that individual differences in students' L1 skills in elementary…
