This longitudinal case study tracks an adult second-language (L2) learner's quality and quantity of encounters with 20 vocabulary items in an English for Academic Purposes course over 3 months. The learner completed pretest and posttest vocabulary knowledge interviews, submitted course materials and notes for analysis, and was observed during…

This article investigates the effect of age of first exposure and the quantity and quality of input to which non-native acquirers (L2ers) are exposed in their acquisition of grammatical gender in Dutch. Data from 103 English-speaking children, preteens and adults were analyzed for gender agreement on definite determiners. It was observed that…

According to Crain and Nakayama (1987), when forming complex yes/no questions, children do not make errors such as "Is the boy who smoking is crazy?" because they have innate knowledge of "structure dependence" and so will not move the auxiliary from the relative clause. However, simple recurrent networks are also able to avoid…

This study examined information about adjective meanings available in adults' spoken discourse in the original 27 CHILDES corpora of typically developing English-speaking children. In order to increase the probability that adjectives would be novel to children to whom they were addressed, only "rare" adjectives were examined (those that occurred…

The aspect hypothesis (Andersen & Shirai, 1994) proposes that language learners are initially influenced by the inherent semantic aspect in the acquisition of tense and aspect (TA) morphology. Perfective past emerges earlier with accomplishments and achievements and progressive with activities. Although this hypothesis has been extensively…

Children with unilateral pre- or perinatal brain injury (BI) show remarkable plasticity for language learning. Previous work highlights the important role that lesion characteristics play in explaining individual variation in plasticity in the language development of children with BI. The current study examines whether the linguistic input that…

Major innovations are becoming available for research in language development and disorders. Among these innovations, recent tools allow naturalistic recording in children's homes and automated analysis to facilitate representative sampling. This study employed all-day recordings during the 2nd year of life in a child exposed to three languages,…

After a teaching experience with the children of Ecuador with so little support, the author has come to greatly appreciate what is available for teachers in the states. Sometimes the best encouragement for a new teacher of FLES is a success story straight from the classroom. In this article, the author shares a few of the tools she has picked up…

Error diagnosis in ICALL typically analyzes learner input in an attempt to abstract and identify indicators of the learner's (mis)conceptions of linguistic properties. For written input, this process usually starts with the identification of tokens that will serve as the atomic building blocks of the analysis. In this paper, we discuss the…

Studies examining factors that influence when words are learned typically investigate one lexical category or a small set of words. We provide the first evaluation of the relation between input frequency and age of acquisition for a large sample of words. The MacArthur-Bates Communicative Development Inventory provides norming data on age of…

This article investigates an argument-adjunct asymmetry in English as a second language (ESL) learners' acquisition of inversion in "wh"-questions. A generative approach (DeVilliers, 1991; Stromswold, 1990) claims that inversion is acquired earlier in argument "wh"-questions than in adjunct "wh"-questions, the asymmetry resulting from their…

The input enhancement hypothesis proposed by Sharwood Smith (1991, 1993) has stimulated considerable research over the last 15 years. This article reviews the research on textual enhancement of input (TE), an area where the majority of input enhancement studies have aggregated. Methodological idiosyncrasies are the norm of this body of research.…

Adult knowledge of a language involves correctly balancing lexically-based and more language-general patterns. For example, verb argument structures may sometimes readily generalize to new verbs, yet with particular verbs may resist generalization. From the perspective of acquisition, this creates significant learnability problems, with some…

The problem. This research study explores an important issue in the field of TESOL (Teaching English to Speakers of Other Languages) and second language acquisition (SLA). Its purpose is to examine the relationship between Vietnamese students' L1 grammar knowledge and their English grammar proficiency. Furthermore, it investigates the extent to…

Purpose: This study assesses the factors that contribute to Spanish and English language development in bilingual children. Method: Seven hundred and fifty-seven Hispanic prekindergarten and kindergarten-age children completed screening tests of semantic and morphosyntactic development in Spanish and English. Parents provided information about…
