Purpose: We measure typically developing monolingual child Spanish speakers' lexical development with a range of standard expressive and receptive tests. We also measure their comprehension of sentences with the existential quantifier "algunos" "some" to determine their abilities to generate "some, but not all" scalar…

The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

Recent studies of appositives have turned up differences between sentence-medial appositives and sentence-final appositives, for instance, in their availability for discourse continuations. Three experiments investigated whether medial appositives are more difficult to comprehend than final appositives and if so why. Experiment 1 tested…

This study explores the effects of receptive derivational affix knowledge, derivative frequency, part of speech, and vocabulary breadth on production of derivatives. Twenty-one speakers of English as a first language and 107 learners of English as a second language were asked to produce derivatives for 90 prompt words on a decontextualized…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

The study investigates which grammar features need high priority of pedagogical intervention to develop implicit knowledge, unlike grammatical features in need of explanation of explicit rules. Two types of data were collected from 29 Korean college students: a sentence completion test in English and a meta-linguistic knowledge test (requiring…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

Morphological knowledge has been identified as a significant sub-skill in bilingual listening comprehension, and lexical researchers consider listening comprehension an essential means for language learning. The current research attempted to examine the crucial four derivative word classes (adverb, adjective, verb, and noun) to represent knowledge…

Derivational knowledge is associated with writing and speaking skills. These skills are essential for EFL students who express themselves in oral presentations or written assignments. Therefore, diagnostic measurement of productive derivational knowledge is of vital importance, especially in regard to the most frequent 1,000 word families that…

This article investigates whether explicit instruction can affect second language (L2) competence in the domain of English quantifier scope. An intervention study was conducted with L1-Mandarin L2-English learners in order to examine (1) whether these learners can learn inverse scope for the structure on which they are instructed…

English articles are thought to be complex, ambiguous and not salient in spoken language, which is why second language (L2) learners of English exhibit usage variability. Much of the L2 acquisition literature seems to agree that L2 learners are affected, one way or another, by their first language (L1). However, the debatable and controversial…

Previous studies in the acquisition of clitic se in Spanish have focused on the syntactic processes needed to perform detransitivization. However, current approaches on event structure reveal that "se" encodes aspectual information which is crucial for its acquisition. We examine the use, intuition and interpretation of the aspectual…

The aim of this study is to analyse the errors of higher education students in English writing tasks. In the study, the paragraphs in the exam papers of 57 preparatory class students, studying at a state university in Turkey in 2017-2018 academic year, were analysed. The study was conducted using qualitative research method. Case study was used in…

Noun-related morphosyntax has not been emphasized in the literature on children with specific language impairment (SLI), yet, across languages, problems in this area are quite apparent. This review is designed to highlight noun-related difficulties that seem to be especially troublesome for these children. A review of the research literature on…

In today's world, educational contexts are getting increasingly multicultural. Although EFL (English as a Foreign Language) classes in Turkey were mostly composed of Turkish students a decade ago, today students from any part of the world are brought together within the frame of various student exchange programs. In Turkish EFL contexts, students…
