Testing the validity of linguistic description against the intuition of native speakers:
The case of Japanese conditionals
Harry Solvang and Naoko Maeda
This paper presents a study of native speaker intuitions regarding the choice of conditional
markers in Japanese in regard to Modal Constraint Approach, whose central claim is that the
choice of the four conditional markers to, tara, ba and nara is governed by the modal contents of
the consequent clause. This study reports the outcome of a computer-based experimental study
on conditionals, where the validity of the current view of modal constraints is being tested
against the judgment of native Japanese speakers from the Kanto district. Our analysis indicates
the current view is in accord with native speakers" intuition in the case of tara and to, but it
definitely needs to be revised in the case of ba. Specifically, against the predictions of the Modal
Constraint Approach we found that even expressions of command, request and prohibition were
regarded as fairly acceptable in a number of cases, suggesting that native intuition is influenced
by a series of factors that come into play with different level of influence on each speaker.
