Differences in the sequence with which children pass the tasks in Wellman and Liu's (2004) theory of mind (ToM) battery is increasingly bringing into question the universal and cultural specifics of children's developing understanding of others' minds. Children from China, Iran, and Turkey pass the knowledge access (KA) task of the battery earlier…

Aspectual and mood morphology are vulnerable domains in adult heritage speakers. This paper investigates the root of such vulnerability within the domain of Turkish evidentiality system by comparing 20 second-generation adult and 20 school-age child Turkish heritage speakers to 20 first-generation immigrants (main input providers for child…

Natural languages contain systematic relationships between verb meaning and verb argument structure. Artificial language learning studies typically remove those relationships and instead pair verb meanings randomly with structures. Adult participants in such studies can detect statistical regularities associated with words in these languages and…

The delayed acquisition of Spanish "ser" and "estar" is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the…

We investigated whether children's inhibitory control (IC) is associated with their ability to produce irregular past tense verb forms as well as learn from corrective feedback following overregularization errors. Forty-eight 3;6 to 4;5 year old children were tested on the irregular past tense and provided with adult corrective input via models of…

Domain restriction is a pervasive if often neglected part of discourse comprehension. Speakers and authors implicitly limit the domain of discourse of quantifiers (e.g., "everyone") and noun phrases (e.g., "the girls"). Our previous research shows that an initial temporal or locative prepositional phrase (PP), which introduces…

Verbal morphology has been identified as a particularly vulnerable domain for adult heritage speakers (HSs) of Spanish, especially when it involves the selection of subjunctive mood. A minimal amount is known, however, about the potential effects of the variability associated with these forms on the acquisition of related epiphenomena, such as the…

The acquisition of voice in Greek remains understudied, especially in heritage populations. Voice in Greek poses a challenging acquisition task for children due to its syncretism, marking various verb classes as well as passives. The present study explores the acquisition of anticausatives, reflexives, and passives in 6-to-8-year-old monolingual…

Data from elicited language tasks can add to the literature on the development of the complex syntax structures of embedded complement clauses in typically developing children. In the current study, preschool-age children (n = 27) participated in two elicited language tasks focusing on three types of embedded complement clauses: infinitival…

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…

Extending previous findings on adult L2 learners' integration of verbal and constructional information, this study investigated how child learners of English as a foreign language produce verbs in target constructions and whether (a) receptive skills and (b) the specific production modality (spoken versus written) modulate the integration process.…

Concept-based language instruction (C-BLI) is a pedagogy guided by sociocultural theory, which has been shown to be effective in facilitating second language learning. Typical activities include materialization by using a schema for a complete orienting basis of an action (SCOBA) and languaging, through which learners' internalization of…

The present study examines the production and intuition of Spanish clitics in clitic left dislocation (CLLD) structures among 26 Spanish heritage speakers (HSs) born and raised in Brazil. We tested clitic production and intuition in contexts in which Spanish clitics vary as a function of the semantic features of the object that they refer to.…

This study investigates the use of high-frequency cognitive verbs - think and believe - in Turkish L2 learners' interlanguage, both in terms of their verb senses and complementation patterns. In line with this purpose, a Sentence Production Task consisting of context-independent items and a Sentence Completion Task consisting of context-dependent…

This paper investigated how production task combined with teacher feedback (in the form of recasts) affects child second language development, and the effects of task complexity on their production performance. 92 child learners of English in three intact classes were assigned to three tasks of different complexity (simple, +complex, ++complex).…
