Purpose: This study focuses on examining how individual differences, including biological, linguistic, and cognitive traits, and prosodic focus affect the computation biases and reaction time (RT) associated with quantity scalar terms in Mandarin-speaking children aged 3-8 years. Method: The participants of this study were 27 Mandarin-speaking…

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…

Purpose: Tests measuring speech comprehension and listening effort for cochlear implant (CI) users may reflect important aspects of real-world speech communication. In this study, we describe the development of a multiple-talker, English-language sentence verification task (SVT) for use in adult CI users to measure speech comprehension and…

Many children with autism spectrum disorder (ASD) demonstrate poor comprehension of language at the sentence level in both the spoken modality and the graphic symbol modality. This study explored whether children with ASD are able to follow directives when presented with a graphic symbol sentence that includes an animated symbol for a verb. A…

This study examines the referential context effect on second-language relative clause ambiguity resolution by proficient L1 Chinese learners who learn English as a foreign language (EFL) and investigates whether the ambiguity resolution process is constrained by individuals' working memory capacity (WMC). It presents a self-paced reading study and…

In sentence comprehension, negative sentences tend to elicit more processing cost than affirmative sentences. A growing body of work has shown that pragmatic context is an important factor that contributes to negation comprehension cost. The nature of this pragmatic effect, however, is yet to be determined. In 4 behavioral experiments, the current…

Purpose: Emotional processing allows us to predict our own and others' behavior, communicate our wants and needs, and understand those of others. Thus, deficits in emotional processing can negatively impact one's quality of life. While changes in emotional processing across several domains (e.g., prosody, faces) in Parkinson's disease (PD) are…

In order to better understand the role of syntactic similarity in a code-switched sentence, the current study explored the effect of similar and different syntactic structures on Chinese-English bilinguals' intra-sentential switching costs. L2 proficiency and switching directions as factors that potentially intervene in bilingual performance were…

Individual differences in reading performance between children appear from the onset of literacy acquisition. One possible explanation for this variability is the influence of inhibition in reading ability, a topic that has received very little research attention. Nevertheless, children often make guessing errors characterized by replacing a word…

Previous research showed that verifying a pictured object mentioned in a preceding sentence takes less time when the pictured object shape is compatible with the described object location or spatial position. In the current work we asked if nonvisual information is integrated into the mental model when the target object shape is implied by virtue…

To identify the relationship between non-verbal working memory and graphic symbol selection, this study examined whether the response time to select target symbols in a sentence construction task differed between two groups: a high non-verbal working memory group and a low non-verbal working memory group. The interaction effect between non-verbal…

Early and late bilinguals both differ in the speed with which they comprehend language or in their processing of sentences compared to monolinguals. This is possibly a result of cross-language interference, differential allocation of cognitive resources, or some other difference in language-dependent processes. This dissertation presents research…

A number of studies have found evidence for the so-called "ambiguity advantage," that is, faster processing of ambiguous sentences compared with unambiguous counterparts. While a number of proposals regarding the mechanism underlying this phenomenon have been made, the empirical evidence so far is far from unequivocal. It is compatible…

It has long been suggested that contextual facilitation effects (hereafter, context effects) reflect the interaction between the construction of an internal representation of context and the processing of a semantically related word (Kuperberg & Jaeger, 2016; Stanovich, 1980). Listening and reading studies have constantly replicated the…

This study compared the sentence hyperbole comprehension performance of Chinese poor readers with various levels of arithmetic proficiency. A total of 168 Chinese poor readers in Grade 1 were recruited, and their nonverbal intelligence, verbal working memory, Chinese receptive vocabulary, Chinese grammatical knowledge, character reading and…
