Few researchers would doubt that ultimate attainment in second language grammar is negatively correlated with age of acquisition, but considerable controversy remains about the nature of this relationship: the exact shape of the age-attainment function and its interpretation. This article presents two parallel studies with native speakers of…

This study explored the second language perceptual accuracy of Japanese geminates (moraic units) by English-speaking learners at three proficiency levels: beginner (28), low-intermediate (42), and advanced (15). Stimuli included singleton and geminate /t/, /k/, /s/ followed by /a/ or /u/ produced by a native speaker in isolated words and carrier…

Research suggests that late bilinguals may have persistent difficulties with the automatic access and use of some second language structures because of a lack of underlying integrated knowledge of those structures. In contrast, early bilinguals show advantages in aspects of language use that require this type of automatic knowledge. This study…

Verbs are one of the basic building blocks of grammar, yet few studies have examined the grammatical, morphological, and phonological factors contributing to lexical access and production of Spanish verb inflection. This report describes an online data set that incorporates psycholinguistic dimensions for 50 of the most common early-acquired…

This study examines how listener judgments of second language speech relate to individual differences in listeners' phonological memory, attention control, and musical ability. Sixty native English listeners (30 music majors, 30 nonmusic majors) rated 40 nonnative speech samples for accentedness, comprehensibility, and fluency. The listeners were…

English is written with interword spacing, and eliminating it negatively affects English readers. Chinese is written without interword spacing, and adding it does not facilitate Chinese readers. "Pinyin" (romanized Chinese) is written with interword spacing. This study investigated whether adding interword spacing facilitates reading in Chinese…

Adult second-language (L2) learners' perception of L2 phonetic segments is influenced by first-language phonological and phonetic properties. It was recently proposed that L2 vocabulary size in adult learners is related to changes in L2 perception (perceptual assimilation model), analogous to the emergence of first-language phonological function…

Some second language (L2) learners return from study-abroad experiences (SAEs) with seemingly no change in their L2 ability. In this study we investigate whether a certain level of internal cognitive resources is necessary in order for individuals to take full advantage of the SAE. Specifically, we examine the role of working memory resources in…

The results of a self-paced reading study with German second language (L2) learners of Dutch showed that noun animacy affected the learners' on-line commitments when comprehending relative clauses in their L2. Earlier research has found that German L2 learners of Dutch do not show an on-line preference for subject-object word order in temporarily…

Recent studies of heritage speakers, many of whom possess incomplete knowledge of their family language, suggest that these speakers may be linguistically superior to second language (L2) learners only in phonology but not in morphosyntax. This study reexamines this claim by focusing on knowledge of clitic pronouns and word order in 24 L2 learners…

Do older English as a second language (ESL) children have the same knowledge of word meanings as English as a first language (EL1) children? How important is vocabulary's role in predicting word recognition in these groups? This study sought to answer these questions by examining the profiles of ESL and EL1 upper elementary aged children, for a…

Using the self-paced reading paradigm, the present study examines whether highly proficient second language (L2) speakers of German (English first language) use case-marking information during the on-line comprehension of unambiguous "wh"-extractions, even when task demands do not draw explicit attention to this morphosyntactic feature in German.…

This study reports on a comparison of the use and knowledge of tense-marking morphemes in English by first language (L1), second language (L2), and specific language impairment (SLI) children. The objective of our research was to ascertain whether the L2 children's tense acquisition patterns were similar or dissimilar to those of the L1 and SLI…

A "text"-translation task and a recognition task investigated the hypothesis that "semantic memory" principally mediates translation from a bilingual's native first language (L1) to her second language (L2), whereas "lexical memory" mediates translation from L2 to L1. This has been held for word translation by the revised hierarchical model (RHM)…

This study explores the relationship between aptitude, phonological memory (PM), and second language (L2) proficiency in nonnovice adult learners of English as an L2. Native speakers of French (N = 77) enrolled in a university Teaching English as a Second Language program were the participants in the study. Exploratory factor analysis revealed…
