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,…

Standard Spanish grammar states that desideratives ("querer que"), directives ("aconsejar que"), purpose clauses ("para que"), causatives ("hacer que"), emotive-factives ("alegrarse de que"), negated epistemics ("no creer que"), dubitatives ("dudar que"), and modals ("ser…

The present study investigated the canonical position of instrumental and locative adverbial phrases in both Japanese sentences and noun phrases to determine whether the canonical positions are parallel. A series of sentence/phrase decision tasks were used to compare sentences with different word-orders, including sentences with SA"dv"OV…

Chinese directional complement (DC) constructions, as a subtype of Chinese multiword sequences, are challenging to acquire for second language (L2) learners. However, little is known about L2 Chinese learners' acquisition of figurative DCs and their comprehension of literal and figurative DCs. This study investigated whether the acquisition of…

The present study investigates L1 and L2 English speakers' knowledge of the "wh"-clausal construction along the parameters of (a) conventionality, distinguishing between high-frequency conventional and low-frequency unconventional formulations ("I asked him why they agreed/why did they agree"), and (b) proposition type,…

The congruency effect--that is, faster and more accurate processing of congruent multiword units, has been demonstrated in multiple studies. It is still unclear, however, what its underlying mechanism is, and how congruency may interact with other factors. Using an acceptability judgement task, this study examined the congruency effect in…

Purpose: The purpose of the study was to evaluate implicit learning in children with developmental language disorder (DLD) by employing a visual artificial grammar learning task. Method: Thirteen children with DLD and 24 children with typical language development between the ages of 8 and 12 years completed a visual artificial grammar learning…

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory…

Formulaic expressions (FEs), such as conventional collocations (e.g., fresh air) and phrases (e.g., take a break), constitute a significant part of language use in our daily lives (Erman & Warren, 2000). FEs are defined as multiword units that holistically represent a single meaning, and they are likely stored and retrieved as unanalyzed…

Collocations are words that have a tendency to co-occur within a few words' spans, e.g., "drink coffee" and "dark chocolate" in English. Growing empirical evidence suggests that both native (L1) speakers and advanced second language (L2) learners process two-word collocations faster than unconnected word pairs, and that…

Embedded questions (EQs) are islands for filler--gap dependency formation in English, but not in Norwegian. Kush and Dahl (2022) found that first language (L1) Norwegian participants often accepted filler-gap dependencies into EQs in second language (L2) English, and proposed that this reflected persistent transfer from Norwegian of the functional…

This study investigates the hypothesis that non-isomorphic syntax-semantics mappings pose a greater challenge for non-native (L2) than for native (L1) speakers, focusing on a previously understudied phenomenon. We carried out an antecedent judgment task with L1 German and L1 Russian-speaking, proficient L2 learners of German to examine Condition C…

Domain restriction is a pervasive if often neglected part of discourse comprehension. Speakers and authors implicitly limit the domain of discourse of quantifiers (e.g., "everyone") and noun phrases (e.g., "the girls"). Our previous research shows that an initial temporal or locative prepositional phrase (PP), which introduces…

This study examined the extent to which textual enhancement and task manipulation affect the learners' attentional processing and the development of second language (L2) grammatical knowledge. A total of 73 Korean college students read an opinion news article in one of four experimental conditions: (1) textually enhanced, careful reading, (2)…

Negative sentences are hard to process when they are presented out of context. When embedded in a context of plausible denial their processing difficulty decreases or is completely eliminated. We investigated in six behavioral experiments whether the processing of negation is eased in a denial context triggered by discourse markers (e.g.…
