This dissertation features a relative clause island, whose status has been known to differ significantly across languages and extraction types. By conducting a series of acceptability judgment experiments with human participants, as well as measuring token-by-token surprisal values among large language models, I demonstrate the following: First,…

Speakers display considerable variability in language use and representations: they may have different pronunciations of the same word, different intended meanings for the same phrases, and different sets of syntactic constraints in their internalized grammars. Comprehenders adapt to such variability by constantly updating their expectations for…

Research on input processing and processing instruction has often employed a scoring method known as trials to criterion to observe the effects of instruction that emerge during training. Despite its common use in this research (see Fernández, 2021) this metric has never been evaluated critically. The present study first discusses several…

In experiments investigating the processing of true and false negative sentences, it is often reported that polarity interacts with truth-value, in the sense that true sentences lead to faster reaction times than false sentences in affirmative conditions whereas the same does not hold for negative sentences. Various reasons for this difference…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

Research on second-language (L2) acquisition has identified linguistic domains that appear to be especially difficult to learn--one such sticking point being syntactic structures that depend on the surrounding discourse. The Interface Hypothesis (IH) explains what makes such constructions problematic by appealing to a modular view of language,…

Grounded or embodied cognition research has employed body-object interaction (BOI; e.g., Pexman et al., 2019) ratings to investigate sensorimotor effects during language processing. We investigated relationships between BOI ratings and nonarbitrary statistical mappings between words' phonological forms and their syntactic category in English;…

Native speakers strongly disprefer novel formulations when a conventional alternative expresses the same intended message, presumably because the more conventional form competes with the novel form. In five studies, second language (L2) speakers were less influenced by competing alternatives than native speakers. L2 speakers accepted novel…

An epicene pronoun is a gender-neutral singular pronoun used in sentences when the gender of the subject is unknown or unspecified. In English, "he" and "they" are commonly-used epicene pronouns. Until recently, "he" has been widely accepted as being grammatically correct. However, many have argued that he is sexist…

Age of acquisition (AoA) refers to the age at which people learn a particular item and the AoA effect refers to the phenomenon that early-acquired items are processed more quickly and accurately than those acquired later. Over several decades, the AoA effect has been investigated using neuroscientific, behavioral, corpus and computational…

Although increasing literature has suggested that emotion-label words (e.g., anger, delight) and emotion-laden words (e.g., thief, bride) were processed differently in native language (L1), there was a lack of neuroimaging evidence showing such differences in second language (L2). The current study compared the cortical responses to emotion-label…

Previous studies on Korean relative clauses (RC) show that, with respect to processing, object-extracted relative clauses (ORC) are more difficult to process at the head noun than subject-extracted relative clauses within temporarily ambiguous contexts. ORCs, however, are predicted by experience-based processing models to incur a greater…

It is a robust finding that ambiguous words are recognized faster than unambiguous words. More recent studies (e.g., Rodd et al. in "J Mem Lang" 46:245-266, 2002) now indicate that this "ambiguity advantage" may in reality be a "polysemy advantage": caused by related senses (polysemy) rather than unrelated meanings…

We present a series of experiments investigating English-speaking children's comprehension of "it"-clefts and "wh"-pseudoclefts. Previous developmental work has found children to have asymmetric difficulties interpreting object clefts. We show that these difficulties disappear when clefts are presented in felicitous contexts,…

When native speakers judge the acceptability of novel sentences, they appear to implicitly take competing formulations into account, judging novel sentences with a readily available alternative formulation to be less acceptable than novel sentences with no competing alternative. Moreover, novel sentences with a competing alternative are more…
