All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

This study delves into the syntactic parsing abilities of children and infants exposed to Catalan as their first language. Focusing first on ages 3 to 6, we conducted two sentence-picture matching tasks. In experiment 1, 3 to 4-year-old children failed in identifying singular third-person subjects within null-subject sentences, although they…

Recent studies in the second language acquisition of negation have focused on polarity items and their licensing contexts. Although several studies show a correlation between higher degrees of second language (L2) proficiency and the acquisition of the target L2 structures, less attention has been given to the relation between the acquisition of…

Recently reported links between rhythm and grammar processing have opened new perspectives for using rhythm in clinical interventions for children with developmental language disorder (DLD). Previous research using the rhythmic priming paradigm has shown improved performance on language tasks after regular rhythmic primes compared to control…

Chinese directional complement (DC) constructions, as a subtype of Chinese multiword sequences, are challenging to acquire for second language (L2) learners. However, little is known about L2 Chinese learners' acquisition of figurative DCs and their comprehension of literal and figurative DCs. This study investigated whether the acquisition of…

This study investigates the interpretation of object-initial sentences in German-speaking children. We addressed the following questions: (1) Which morphosyntactic cues do children deploy to process object-initial sentences? (2) Which executive function (EF) abilities support them during this task? This study examined the effect of case and number…

Task repetition is being increasingly examined in the fields of second language acquisition and task-based language teaching, and the findings have revealed insightful theoretical and pedagogical implications for foreign language instruction. However, previous research has mainly focused on speaking tasks, and the role of different types of task…

The most recent studies on the acquisition of evidentiality, be it morphologically or syntactically encoded, have argued that the comprehension lag detected is due to factors having to do with others' authority or mental perspective, where "others" stands for other individuals involved in the experiment in various manners (e.g., the…

Languages vary according to which morphosyntactic forms of embedding are present in the grammar as well as to which of these forms allow recursive embedding. The present study examines how German-speaking children discover which forms of embedding are recursive. In German, possessive modifiers are expressed by several structural options (i.e.,…

This study examines the learning patterns of intermediate and advanced Korean learners in the acquisition of causative expressions according to their proficiency and the causative sentence type. We measured their grammatical knowledge using three types of grammaticality judgment tasks (GJTs) and self-paced reading tasks (SPRTs) differing in time…

Formulaic expressions (FEs), such as conventional collocations (e.g., fresh air) and phrases (e.g., take a break), constitute a significant part of language use in our daily lives (Erman & Warren, 2000). FEs are defined as multiword units that holistically represent a single meaning, and they are likely stored and retrieved as unanalyzed…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…

Recent approaches to the "that"-trace phenomenon in English include syntactic analyses based on the principle of Anti-locality and a sentence production analysis based on the Principle of End Weight. These analyses have many similarities, but they differ in their predictions for second language (L2) speakers. In an Anti-locality…

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…

Purpose: This study examined two markers of language impairment (LI) in a single experiment, testing sentence imitation and grammatical morphology production using an imitation task with masked morphemes. One goal was to test predictions of the morphological richness account of LI in Czech. We also tested the independent contributions of language…
