This study investigates the developmental trajectory of progressive construction among Chinese and Japanese EFL learners through a usage-based approach. A total of 600 written essays, produced by EFL learners from China and Japan with proficiency levels ranging from elementary to upper-intermediate, were analyzed. The findings reveal that advanced…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

We revisit morpheme studies to evaluate the long-standing claim for a universal order of acquisition. We investigate the L2 acquisition order of six English grammatical morphemes by learners from seven L1 groups across five proficiency levels. Data are drawn from approximately 10,000 written exam scripts from the Cambridge Learner Corpus. The…

This paper investigates how learners interpret definite plural noun phrases (e.g., "the tigers") and bare (article-less) plural noun phrases (e.g., "tigers") in their second language. Whereas Spanish allows definite plurals to have both generic and specific readings, English requires definite plurals to have specific, nongeneric readings. Generic…

Children with SLI have difficulty with tense and agreement morphology. This study examined the proficiency of these children and their typically developing peers with the coordination of tense and aspect markers in two-clause sentences. Scenarios designed to elicit past tense were presented to five- to eight-year-old children with SLI (n = 14) and…

Young monolingual children typically demonstrate frequent tense shifting during narrative development, whereas older children maintain a consistent narration tense. Therefore, inconsistent tense usage in older children could be an indication of overall limited language skills. However, information regarding tense use in bilinguals has been…

This study examines the storage versus composition of Spanish inflected verbal forms in first language (L1) and second language (L2) speakers of Spanish. L2 participants were selected to have mid-to-advanced proficiency, high classroom experience, and low immersion experience, typical of medium-to-advanced foreign language learners. Participants…

The acquisition of the aspectual difference between the preterit and imperfect in the past tense and the acquisition of the contrast between subjunctive and indicative mood are classic problem areas in second language (L2) acquisition of Spanish by English-speaking learners (Collentine, 1995, 1998, 2003; Salaberry, 1999; Slabakova & Montrul, 2002;…

This study compared the use of English past tense in a group of Spanish-English bilingual children with language impairment (BLI) to younger groups of bilinguals with typical and atypical language development reported in an earlier study. Ten children with BLI enrolled in 3rd-6th grade participated. Children supplied 12 regular, 12 irregular, and…

English learners of French whose first language (L1) does not mark the perfective/imperfective distinction have shown verb semantic influence and an overall preference for perfective over imperfective in their use of second language (L2) tense-aspect markers. This study investigated whether learners whose L1 marks the perfective/imperfective…

In 3 experiments, 2 year olds imitated sentences that contained English or non-English functors (articles and verb inflections), and were controlled for suprasegmental and segmental factors. Children omitted English functors more often than non-English functors, thus indicating perceptual sensitivity to familiar elements. (RH)

It has been observed that there is a strong association between the inherent (lexical) aspect of verbs and the acquisition of tense-aspect morphology (the aspect hypothesis; Andersen & Shirai, 1994). To investigate why such an association is observed, this study examined the influence of inherent aspect and learners' first language (L1) on the…

This pilot study investigated Standard American English (SAE) morphological development for 15 bilingual Hispanic preschoolers. Analysis of data from spontaneous language samples revealed emergent use of Brown's (1973) 14 grammatical morphemes. Because mastery generally was later than for SAE speakers, clinicians are urged to use caution when…

A study tested the hypothesis that the production of derivational (as contrasted with grammatical) morphemes is acquired through a systematic development of three distinct psychological processes: comprehension, segmentation, and production, regardless of whether the individual is a first- or second-language learner. The subjects were 32 children,…
