Compound surnames in Japanese show complex phonological patterns, which pose challenges to current theories of phonology. This dissertation proposes an account of the segmental and prosodic issues in Japanese surnames and discusses their theoretical implications. Like regular compound words, compound surnames may undergo a sound alternation known…

This study investigates the knowledge of unaccusativity in Japanese native, heritage, and second/foreign language speakers with respect to licensing of floating numeral quantifiers (FNQs) by unaccusative and unergative subjects (the "FNQ diagnostic"). Two acceptability judgment experiments were conducted to examine (i) whether and how…

There have been three competing analyses regarding the canonical word order of Japanese ditransitive sentences: a) "S-'ga' IO-'ni' DO-'o' V" is the canonical word order rather than "S-'ga' DO-'o' IO-'ni' V", b) both word orders are canonical, and c) the canonical word order depends on the type of the verb. The present study…

Syntactic bootstrapping facilitates children's initial learning of verb meanings based on syntactic information. A challenging case is the argument-drop languages, where the number of argument NPs is not a reliable cue for distinguishing between transitive and intransitive verbs. Despite this fact, the availability of syntactic bootstrapping in…

The present study aimed to examine whether distributed practice works better than massed practice for proceduralization of grammatical knowledge. Learners of Japanese as a second language were trained on an element of Japanese morphology under either massed or distributed practice conditions. Results showed that massed practice led to accurate…

In this article, we challenge the notion that aptitude--operationalized as grammatical sensitivity as measured by the Words in Sentences section of the Modern Language Aptitude Test--is central to adult second language (L2) acquisition. We present the findings of a study on the acquisition of two properties of Japanese, head-final word order and…

This article reports the findings of a study in which we investigated the possible effects of word order on the acquisition of case marking. In linguistic typology (e.g. Greenberg, 1963) a very strong correlation has been shown between dominant SOV (subject object verb) word order and case marking. No such correlation exists for SVO (subject verb…

This article suggests a method to deal with cross-linguistic differences in children with Specific Language Impairment. The differences in vulnerable structures reflect typological properties of the surrounding language (e.g., Leonard 2014a, 2014b). This article adds a developmental perspective to the discussion by interpreting the vulnerable…

This year's conference theme, "Be Seen, Be Heard," reflected not only our goal of celebrating our achievements but also represented our intent of making sure everyone's voices are heard, especially during 2017's difficult political climate. The conference opened with a motivating address from Dean Laura E. Lyons, followed by an…

In natural languages, the mapping from surface form to meaning is often quite complex, and hence the acquisition of the phenomena at the boundary between syntax and semantics has been one of the central issues in current acquisition research. This study addresses the issue of whether children have adult-like knowledge of LF "wh"-movement and its…

There have been many studies on the acquisition of English unaccusative verbs which make use of learner corpora. Most of these studies have so far concluded that even advanced learners of English ungrammatically passivize unaccusative verbs and produce sentences such as "*The accident was happened" and "*The mobile phone was…

Korean learners of the Japanese language and Japanese learners of the Korean language not only feel that it is easier to learn the respective foreign language, but also acquire Japanese and Korean faster than learners from other countries because of the grammatical similarity between Japanese and Korean. However, the similarity of grammatical…

It has long been argued that prosodic cues may facilitate syntax acquisition (e.g., Morgan, 1986). Previous studies have shown that infants are sensitive to violations of typical correlations between clause-final prosodic cues (Hirsh-Pasek et al., 1987) and that prosody facilitates memory for strings of words (Soderstrom et al., 2005). This…

This dissertation explores the second language acquisition of Mandarin Chinese tones by speakers of non-tonal languages within the framework of Optimality Theory. The effects of three L1s are analyzed: American English, a stress-accent language; Tokyo Japanese, a lexical pitch accent language; and Seoul Korean, a non-stress and non-pitch accent…

Previous studies on the second language acquisition of telicity have suggested that learners can use morphosyntactic cues to interpret sentences as telic or atelic even in cases where the cues differ in the first language (L1) and second language (L2) (Slabakova, 2001, 2005; Gabriele, 2008; Kaku et al., 2008a, 2008b). The present study extends…
