Parallelism Between Sentence Structure and Nominal Phrases in Japanese: Evidence from Scrambled Instrumental and Locative Adverbial Phrases.

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 SAdvOV (S is subject phrase, Adv adverb, O object phrase and V verb), AdvSOV, SAdvOV and SOAdvV word orders. SAdvOV word order was found to be the most quickly processed, for both instrumental adverbial (Experiment 1) and locative adverbial phrases (Experiment 2). Thus, the canonical position for these adverbial phrases is identified as the position immediately preceding the object (Theme argument). This finding was replicated when the same experimental methods were applied to event-denoting noun phrases. Adverbial adjuncts in the initial position (AdvON, N is noun phrase) were processed more quickly and accurately than noun phrases with adverbial phrases in the second position (OAdvN), for both instrumental adverbial (Experiment 3) and locative adverbial phrases (Experiment 4). Therefore, the position immediately preceding the object is the canonical position for both instrumental and locative adverbial phrases in sentences and in noun phrases. In conclusion, this indicates that the base structure of a sentence is shared by its related noun phrase.

Ambiguity in the processing of Mandarin Chinese relative clauses: One factor cannot explain it all.

This study addresses the question of whether native Mandarin Chinese speakers process and comprehend subject-extracted relative clauses (SRC) more readily than object-extracted relative clauses (ORC) in Mandarin Chinese. Presently, this has been a hotly debated issue, with various studies producing contrasting results. Using two eye-tracking experiments with ambiguous and unambiguous RCs, this study shows that both ORCs and SRCs have different processing requirements depending on the locus and time course during reading. The results reveal that ORC reading was possibly facilitated by linear/temporal integration and canonicity. On the other hand, similarity-based interference made ORCs more difficult, and expectation-based processing was more prominent for unambiguous ORCs. Overall, RC processing in Mandarin should not be broken down to a single ORC (dis)advantage, but understood as multiple interdependent factors influencing whether ORCs are either more difficult or easier to parse depending on the task and context at hand.
