Most words in natural languages are polysemous; that is, they have related but different meanings in different contexts. This one-to-many mapping of form to meaning presents a challenge to understanding how word meanings are learned, represented, and processed. Previous work has focused on solutions in which multiple static semantic…

In this dissertation, I investigate how people navigate ambiguity in everyday speech, with a focus on quantifier-negation sentences. Combining corpus analysis, behavioral experiments, and computational modeling in the Rational Speech Act framework, I explore preferred interpretations of quantifier-negation and examine the contexts and prosodies…

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…

Lexical access is highly contextual. For example, vowel (rime) information is prioritized over tone in the lexical access of isolated words in Mandarin Chinese, but these roles are flipped in constraining contexts. The time course of these contextual effects remains unclear, and so here we tracked the real-time eye gaze of native Mandarin speakers…

The aim of the study is to examine the effect of sentential context on lexical ambiguity resolution in Greek adults and typically developing children. Context and word frequency are factors that can affect lexical processing, however, the role of them has not been thoroughly examined in Greek. To this aim, we assessed sentence context effects in…

Speakers vary in their pronunciations of the sounds in their native language. Listeners use lexical knowledge to adjust their phonetic categories to speakers' idiosyncratic pronunciations. Lexical information can, however, be inconclusive or become available too late to guide this phonetic retuning. Sentence context is known to affect lexical…

Previous research has documented that children count spatiotemporally-distinct partial objects as if they were whole objects. This behavior extends beyond counting to inclusion of partial objects in assessment and comparisons of quantities. Multiple accounts of this performance have been proposed: children and adults differ qualitatively in their…

In two experiments, we examined the impact of color on cognitive performance by asking participants to categorize stimuli presented in three different colors: red, green, and gray (baseline). Participants were either asked to categorize the meaning of words as related to the concepts of "go" or "stop" (Experiment 1) or to…

The current study tests the hypothesis that language comprehension is, in part, influenced by language exposure, and the biases that people develop are related to the frequency of exposure to different linguistic input, like, for instance, pronoun coreference. As comprehenders filter the linguistic input they encounter, we ask, what is the impact…

Many languages encode phi-features via overt morphology, yet children's use of this morphology in comprehension tasks varies widely. Here, we use a picture-selection task to test comprehension of Spanish verbal agreement and clitics, comparing performance across and within each paradigm to examine the effect of two factors: (i) phonological…

Translation ambiguity, which occurs commonly when one word has more than one possible translation in another language, causes language processing disadvantage. The present study investigated how Chinese--English bilinguals process translation-ambiguous words, and whether it is affected by the second language (L2) proficiency and sentence context,…

This dissertation adopts an experimental approach to studying lie judgments. It focuses on lie judgments to different types of meaning within a pragmatic framework -- namely bare linguistic meaning, explicature, and implicature -- to study whether the (in)directness of communicated false content affects the extent to which an utterance is judged…

Previous research has uncovered that, despite the omnipresence of focus in utterances, children typically do not compute the exhaustivity inference associated with cleft(-like) syntactic focus constructions at adult-like levels before 7 years of age. Children's comparable limitations with lexically triggered scalar implicatures, inferences with an…

This study investigates the complex dynamics of semantic change and cultural adaptation of metaphor in multilingual communication. The research uses cognitive linguistics, sociolinguistics, and pragmatics to develop a model that explains the fundamental mechanisms of metaphorical expression and comprehension across languages and cultures. Using…

This article examines how semantic memory processes influence the items that are considered by decision makers in memory-based preferential choice. Experiments 1A through 1C ask participants to list the choice items that come to their minds while deliberating in a variety of everyday choice settings. These experiments use semantic space models to…
