Event-related brain indices of Japanese scrambling

This study examined the processing of Japanese wh-questions with preposed (scrambled) vs. in-situ (canonical SOV word order) wh-objects, and of yes/no-questions with scrambled vs. in-situ demonstrative objects. Questions with scrambled objects elicited bilateral slow anterior negative potentials between filler and gap. Scrambled demonstratives elicited P600 effects following the filler and (L)AN/P600 effects at the gap, while scrambled wh-words elicited primarily (L)AN effects at the gap. This replicated effects in response to filler-gap dependencies created by wh-movement in other languages, supporting the existence of universal parsing operations for all types of filler-gap dependencies. We suggest that these results are most generally compatible with notions of canonicity in sentence processing.

On the processing of Japanese wh-questions: An ERP study

The processing of Japanese wh-questions was investigated using event-related brain potentials (ERPs). Unlike in English or German, a wh-element in Japanese need not be displaced from its canonical position, but instead needs a corresponding Q(uestion)-particle to indicate its interrogative scope. We tested to see if there were any processing correlates specific to these features of Japanese wh-questions. Both mono-clausal and bi-clausal Japanese wh-questions elicited right-lateralized anterior negativity (RAN) between wh-words and corresponding Q-particles, relative to structurally-equivalent yes/no-question control conditions. These results suggest a reliable neural processing correlate of the dependency between wh-elements and Q-particles in Japanese, similar to effects of (left) anterior negativity between wh-fillers and gaps in English and German, but with a right- rather than left-lateralized distribution. It is suggested that wh-in-situ questions in Japanese are processed by the incremental formation of a long-distance dependency between wh-elements and their Q-particles, resulting in a working memory load for keeping track of scopeless wh-elements.

Grammatical and pragmatic factors in the interpretation of Japanese null and overt pronouns

Abstract Pronoun interpretation in English has been demonstrated to be sensitive to an interaction between grammatical and pragmatically driven factors. This study investigated the interpretation of pronouns in Japanese, which has both null and overt forms. Thirty-two native speakers of Japanese per experiment participated in passage completion studies with transfer-of-possession contexts (Experiment 1) or implicit causality contexts (Experiment 2), varying prompt type, aspect, and topic/nominative-marking of the previous subject. Two judges annotated reference and coherence relations in the completed passages. Japanese overt pronouns were revealed to pattern closely with English overt pronouns in their sensitivity to pragmatic factors, whereas null pronouns showed a mixed resilience to pragmatic factors. Topic-marking only showed marginal effects on reference in limited contexts. Despite different degrees of sensitivity to pragmatic factors, Japanese null and overt pronouns were both mostly subject-biased, casting doubt on the existence of a division of labor between the two forms. There was also an intrinsic link between reference and coherence relations throughout the experiments. We discuss the overall results in terms of language specificity and universality, the latter of which includes interactions between grammatical and pragmatic factors and the importance of discourse coherence in the interpretation of various pronouns across languages.
