Compositionality has been a central concept in linguistics and philosophy for decades, and it is increasingly prominent in many other areas of cognitive science. Its status, however, remains contentious. Here, I reassess the nature and scope of the principle of compositionality (Partee, 1995) from the perspective of psycholinguistics and cognitive…

This dissertation investigates the nature of the interface between morphosyntax and cognition. My goal is to connect formal semantic theories of meaning with theories of cognition, drawing on the initial hypothesis that the interface between language and cognition is transparent. I look at different forms of adjectival comparatives -- positive and…

This article reports on an empirical study of L3 Mandarin, aiming to shed light on transfer effects and their interaction with other factors throughout the L3 acquisition trajectory. A fill-in-the-blank task was employed to examine L2 and L3 acquisition of three types of Mandarin sentence-final particle clusters. Participants in the study were…

After the pandemic has ceased, high expectations have been raised for the tourism industry to generate quick and substantial income for Thailand as a remedy for the sluggish economy. The Tourism Authority of Thailand (TAT) plays a key role in informing and inviting foreign tourists to visit the country. TAT's official English website is another…

Theories of reading comprehension have widely predicted a role for syntactic skills, or the ability to understand and manipulate the structure of a sentence. Yet, these theories are based primarily on English, leaving open the question of whether this remains true across typologically different languages such as English versus Chinese. There are…

Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

This study investigated why object-gap relative clauses (RCs) are dominant in early child Mandarin. We discuss how restrictive-RCs differ from pseudo-RCs syntactically and pragmatically, and examine how these two types of RCs are distributed in the RC utterances of ten children and their caregivers. The results showed that (a) Mandarin-speaking…

Having heard "a pimwit", English-speakers assume that "the pimwit" is also possible. This type of productivity is attributed to syntactic categories such as NOUN and DETERMINER, but the key question is "how" do humans become endowed with these categories in the first place. We propose a novel approach that combines…

Purpose: Children's vocabulary and syntactic skills vary upon school entry in depth and breadth, persistently influencing academic performance, including reading. Enhancing early communicative abilities through multisensory, playful, and conversational experiences is essential and will benefit children's school readiness. This study investigated…

Purpose: Children who are deaf and hard of hearing (DHH) have documented deficits with complex syntax and vocabulary knowledge. Mental state verbs (MSVs) are necessary for some kinds of complex syntax use and communicate abstract concepts needed for academic language. The purpose of this study was to examine the frequency, diversity, and syntactic…

This study investigated the argumentation of 27 junior high school students in building their creative reasoning and the relationship between students' argumentation and their mathematical literacy skills. The data collected using mathematical literacy test and assessment rubric and were analyzed using qualitative content analysis. The study found…

The primary objective of this study was to compare the syntactic complexity of informational texts produced by fifth-grade students (a) with and without language impairment and (b) with and without native English-speaking proficiency on a curriculum-based reading and writing task. Expository writing samples produced by 114 children enrolled in the…

Children who speak non-standardized language varieties are at risk for both over- and under-referral to speech-language and special education services (e.g., Morgan et al., 2016; Pearson et al., 2014). Extensive research with bidialectal (Craig, 2016; Kohn et al., 2021) and bilingual (Goldstein, 2022; Paradis et al., 2021) children has shown the…

Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

We investigate German-Russian bilingual children's sensitivity to formal and semantic cues when assigning gender to nouns in German. Across languages, young children have been shown to primarily rely on phonological cues, whereas sensitivity to semantic and syntactic cues increases with age. With its semi-transparent gender assignment system,…
