We investigated toddlers' understanding of the hierarchical syntactic configurations that constrain the referential meanings of reflexives and pronouns. In particular, reflexives must co-refer with the c-commanding antecedent within the local domain (Principle A) (e.g., He[subscript i] washes himself[subscript i]. John[subscript i] knows that…

It has been well documented that formulaic language (such as collocations; e.g., "provide information") enjoys a processing advantage over novel language (e.g., "compare information"). In natural language use, however, many formulaic sequences are often inserted with words intervening in between the individual constituents…

During reading, high-frequency words consistently receive shorter fixation durations relative to low-frequency words. However, how frequently a given word is experienced can vary across an individual's education. In the current study, the effects of both childhood and college-level word frequency on fixation durations were examined to assess the…

The Chinese writing system is different from English in that individual words both comprise one to four characters and are not separated by clear word boundaries (e.g., interword spaces). These differences raise the question of how readers of Chinese know where to move their eyes to support efficient lexical processing? The widely accepted…

F0 contours convey multiple types of information, including lexical and post-lexical meanings, as well as affective and socio-indexical indicators. This dissertation investigates the interaction between lexical tone and sentence-level intonation in Thai, focusing on how sentence position influences the acoustic realization and perceptual…

Many studies have shown the double processing of negation, suggesting that negation integration into sentence meaning is delayed. This contrasts with some researches that have found that such integration is rather immediate. The present study contributes to this debate. Affirmative and negative compound sentences (e.g., "because he was…

Although the linguistic properties of polar questions have been extensively studied, comparatively little is known about how polar questions are processed in real time. In this paper, we report on three eye-tracking experiments on the processing of positive and negative polar questions in English and French. Our results show that in the early…

We studied English-learning children's ability to learn the meanings of novel words from sentences containing truth-functional negation (Exp1) and to use the semantics of negation to inform word meaning (Exp2). In Exp1, 22-month-olds (n = 21) heard dialogues introducing a novel verb in either negative-transitive "("Mary didn't blick the…

In successful communication, it is critical to have the ability to identify what a speaker is referring to from previously mentioned information. This ability requires the identification of the topic initially introduced by lexical forms and its continuity in discourse expressed by anaphora such as null and pronominal forms in the subsequent…

The purpose of the current study was to better understand performance variability in sentence comprehension in people with aphasia, compared to a control group of adults. People with aphasia often have difficulty understanding sentences that are complex in structure and meaning. Comprehension difficulty is variable, which may confound the clinical…

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…

Although a large literature demonstrates that object-extracted relative clauses (ORCs) are harder to process than subject-extracted relative clauses (SRCs), there is less agreement regarding where during processing this difficulty emerges, as well as how best to explain these effects. An eye-tracking study by Staub, Dillon, and Clifton (2017)…

Understanding how a child's language system develops into an adult-like system is a central question in language development research. An increasingly influential account proposes that the brain constantly generates top-down predictions and matches them against incoming input, with higher-level cognitive models serving to minimize prediction…

We investigate the processing of "wh" questions in Niuean, a VSO ergative-absolutive Polynesian language. We use visual-world eye tracking to examine how preference for subject or object dependencies is affected (a) by case marking of the subject (ergative vs. absolutive) and object (absolutive vs. oblique), and (b) by the transitivity…

Two word-learning experiments were conducted to investigate the understanding of negative sentences in 18- and 24-month-old children. In Experiment 1, after learning that "bamoule" means "penguin" and "pirdaling" means "cartwheeling," 18-month-olds (n = 48) increased their looking times when listening to…
