A factor analysis of a test battery that included early first-language (L1) achievement, L1 cognitive ability, second-language (L2) aptitude, and L2 affective measures to predict oral and written L2 proficiency was conducted. The analysis yielded 4 factors that were labeled Language Analysis, composed of L1 and L2 language comprehension, grammar, vocabulary, and inductive language learning measures; Phonology/Orthography, composed of L1 and L2 phonemic coding and phonological processing measures; IQ/Memory, composed of L1 intelligence and L2 paired-associate learning measures; and Self-Perceptions of Language Skills, composed of L2 motivation and L2 anxiety measures. The 4 factors explained 76% of the variance in oral and written L2 proficiency. Findings support the view that L2 aptitude is componential. Results are discussed in the context of long-term L1-L2 relationships and individual differences in L2 learning. (2002) OBserved that research on second/foreign-language (L2) aptitude has "languished" over the last three decades. He speculated that aptitude research had generated little interest because of its "perceived irrelevance to L2 acquisition in communication contexts" (p. 69). Previously, Skehan (1998) had proposed that the concept of L2 aptitude has been unpopular because of its implicit assumptions that a special talent exists for language learning-that learning a language is different from learning other skills. Furthermore, he proposed that language aptitude is stable over time; that is, aptitude is not influenced signifi-
