テーマ  Incremental or delayed processing? A cross-linguistic eye-tracking study of wh-questions in Japanese and English

 

要 旨  

The processing of wh-questions offers valuable insights into sentence
comprehension in first (L1) and second (L2) language learners. While L1
English speakers actively resolve filler-gap dependencies by prioritizing
the first verb phrase, the strategies employed by L2 learners remain
debated. The Shallow Structure Hypothesis (SSH) posits that L2 learners
rely on global parsing strategies, delaying interpretation until sufficient
context is available. This study investigates whether Japanese L2 learners
of English process wh-questions incrementally, like native speakers, or
adopt delayed strategies influenced by their L1.

Experiment 1 used the visual world eye-tracking paradigm to examine
Japanese L2 learners of English (n=51) and native English speakers (n=11)
processing ambiguous wh-questions (e.g., "Where did Lizzie tell someone
that she was going to catch butterflies?"). L2 learners, like native
speakers, fixated more on the main clause interpretation from the onset of
the question, with key-press responses confirming this preference (p<.001).
These results challenge the SSH, demonstrating that L2 learners actively
resolve filler-gap dependencies during incremental processing.

In Experiment 2, Japanese participants processed similar sentences in their
L1 (e.g., "
どこでリジーは蝶々を捕まえたと言ったの?"). Unlike in English, participants delayed
resolving filler-gap dependencies until the sentence's end, relying on
particle information. This behavior aligns with the syntactic structure of
Japanese, where embedded clauses precede main clauses.

These findings reveal that L2 processing adapts to the grammar of the
target language rather than being directly influenced by L1 strategies.
While English promotes incremental processing, Japanese encourages a more
delayed approach. This study underscores the universality of incremental
processing in language comprehension, shaped by language structure and
proficiency across typologically distinct languages.
