It has been well-documented that although children around 4 years start to attribute false beliefs to others in classic false-belief tasks, they are still less able to evaluate the truth-value of propositional belief-reporting sentences, especially when belief conflicts with reality. This article investigates whether linguistic cues, verb…

Acquisition of an argument structure may be affected by the diversity of lexical types that appear in that structure (Conwell et al., 2011; Yang, 2016). Seventy-two 5- and 6-year-old English-speaking children completed a learning study where they were exposed to a novel argument structure and then tested on their ability to comprehend it. The…

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)…

Past work has suggested that L1 readers retrieve idioms (i.e., "spill the tea") directly vs. matched literal controls ("drink the tea") following unbiased contexts, whereas L2 readers process idioms more compositionally. However, it is unclear whether this occurs when a figuratively or literally biased context…

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…

Natural languages contain systematic relationships between verb meaning and verb argument structure. Artificial language learning studies typically remove those relationships and instead pair verb meanings randomly with structures. Adult participants in such studies can detect statistical regularities associated with words in these languages and…

Mandarin requires neither determiners nor morphological inflections, which casts doubt on Mandarin-speaking children's ability to use function words as a syntactic bootstrapping tool to identify the form class of a new word. This study examined 3- and 5-year-old Mandarin learners' ability to use function words to interpret new words as either…

We test the comprehension of transitive sentences in very young learners of Mandarin Chinese using a combination of the weird word order paradigm with the use of pseudo-verbs and the preferential looking paradigm, replicating the experiment of Franck et al. (2013) on French. Seventeen typically-developing Mandarin infants (mean age: 17.4 months)…

We propose that negative clauses are generally interpreted as if the affirmative portion of the clause is under discussion, a likely topic. This predicts a preference for affirmative (topical) antecedents over negative antecedents of a following missing verb phrase (VP). Three experiments tested the predictions of this hypothesis in sentences…

This dissertation investigates how parametric variation of linguistic properties leads to similarities and differences in language processing across the levels of words, grammatical features, and sentences. For a truly generalizable theory of psycholinguistics, the languages surveyed should not be constrained to English (Garnham, 1994; Norcliffe…

Purpose: This study examined whether college students with developmental language disorder (DLD) showed similar sensitivity to verb bias information during real-time sentence processing as typically developing (TD) peers. Method: Seventeen college students with DLD and 16 TD college students participated in a mouse-tracking experiment that…

This study investigates the influence of semantic maturation on early lexical development by examining the impact of contextual diversity--known to influence semantic development--on word promotion from receptive to productive vocabularies (i.e., comprehension-expression gap). Study 1 compares the vocabularies of 3685 American-English-speaking…

This study examines whether second language (L2) learners predict upcoming language prior to the verb in Japanese. Taking the dependency involving negative polarity adverbs -- "zenzen" 'at all' and "amari" '(not) very' -- as a test case, this study examined whether Japanese native speakers and L2 learners of Japanese, aided by…

Implicit causality (IC) is a well-known phenomenon whereby certain verbs appear to create biases to remention either their subject or object in a causal dependent clause. This study investigated to what extent Korean learners of English made use of IC information for predictive processing at a discourse level, and whether L2 proficiency played a…

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…
