Children's status as research participants in applied linguistics has been largely overlooked even though unique methodological and ethical concerns arise in projects where children, rather than adults, are involved. This article examines the role of children as research participants in applied linguistics and discusses the limitations of…

We examined case-marking variation in heritage Polish, Russian, and Ukrainian. Comparing heritage to homeland Polish and Ukrainian speakers, we found only a few types and a few tokens of systematic distinction between heritage and homeland varieties. A total of 6,291 instances of nouns and pronouns were extracted from transcribed conversations…

While previous sociolinguistic research has demonstrated that children faithfully acquire probabilistic input constrained by sociolinguistic and linguistic factors (e.g., gender and socioeconomic status), research suggests children regularize inconsistent input-probabilistic input that is not sociolinguistically constrained (e.g., Hudson Kam &…

This study investigates relationships between acquisition of exhaustivity in single and multiple "wh"-questions, mastery of semantic and pragmatic aspects of quantifier comprehension, and general skills in receptive grammar. The participants of the study were 25 Polish monolingual typically developing children aged 4;02-6;02, who were…

Many English-speaking children use plural nominal forms in spontaneous speech before the age of two, and display some understanding of plural inflection in production tasks. However, results from an intermodal preferential study suggested a lack of "comprehension" of nominal plural morphology at 24 months of age (Kouider, Halberda, Wood,…

The phenomenon of regularization -- learners imposing systematicity on inconsistent variation in language input -- is complex. Studies show that children are more likely to regularize than adults, but adults will also regularize under certain circumstances. Exactly why we see the pattern of behaviour that we do is not well understood, however.…

Artificial language learning (ALL) experiments have become an important tool in exploring principles of language and language learning. A persistent question in all of this work, however, is whether ALL engages the linguistic system and whether ALL studies are ecologically valid assessments of natural language ability. In the present study, we…

The ability to generate novel utterances compositionally using generative knowledge is a hallmark property of human language. At the same time, languages contain non-compositional or idiosyncratic items, such as irregular verbs, idioms, etc. This dissertation asks how and why language achieves a balance between these two systems--generative and…

This study investigates the interpretation of disjunction words (English or) in negative sentences by Turkish- and German-speaking children. Both children and adults were asked to judge Turkish/German sentences corresponding to the English sentence "This animal did not eat the carrot or the pepper." Children acquiring both languages…

This study investigates 3- to 5-year-old children's sensitivity to lexical, intonational and gestural information in the comprehension of speaker uncertainty. Most previous studies on children's understanding of speaker certainty and uncertainty across languages have focused on the comprehension of lexical markers, and little is known about the…

Traditionally, acquisition of syntactic knowledge and the development of sentence comprehension behaviors have been treated as separate disciplines. This article reviews a growing body of work on the development of incremental sentence comprehension mechanisms and discusses how a better understanding of the developing parser can shed light on two…

Models of language acquisition are constrained by the information that learners can extract from their input. Experiment 1 investigated whether 3-month-old infants are able to encode a repeated, unsegmented sequence of five syllables. Event-related-potentials showed that infants reacted to a change of the initial or the final syllable, but not to…

This study investigates the knowledge of unaccusativity in Japanese native, heritage, and second/foreign language speakers with respect to licensing of floating numeral quantifiers (FNQs) by unaccusative and unergative subjects (the "FNQ diagnostic"). Two acceptability judgment experiments were conducted to examine (i) whether and how…

This article proposes that second language learners can use indirect positive evidence (IPE) to acquire a phonological grammar that is a subset of their L1 grammar. IPE is evidence from errors in the learner's L1 made by native speakers of the learner's L2. It has been assumed that subset grammars may be acquired using direct or indirect negative…

This article presents a study of preschool-aged children's knowledge of the semantics of the negative polarity item (NPI) "any". NPIs like "any" differ in distribution from non-polarity-sensitive indefinites like "a": "Any" is restricted to downward-entailing linguistic environments (Fauconnier 1975, 1979;…
