When Negative Statements are Easier Masaya Yoshida Cognitive Neuroscience of Language Laboratory, Department of Linguistics, University of Maryland at College Park masaya@wam.umd.edu CUNY Sentence Processing Conference March 21-23, 2002 City University of New York Abstract In this study I will provide evidence for a predictive mechanism in Japanese sentence processing, and show that negative statements are easy to process in certain situations. Goals • To provide evidence for a predictive mechanism in Japanese sentence processing. (Miyamoto and Takahashi 2001) • To show that in certain situations, negative statements are easy to process. Syntactic Dependencies allow for Predictions X Y PREDICTION English Wh-phrase Ditransitive Verb Japanese Wh-Phrase Two Objects NPI Gap Two Objects Q-Marker Ditransitive Verb Negation How to Diagnose a Prediction Observe slowdown in reading when predictions are not confirmed (1) Wh …Aff…QM X slow down (2) Wh …QM…Aff Aff = Affirmative QM = Question Marker (3) Senmu-ga donna-pasokon-o director-Nom what-kind-computer-Acc tukatteiru-to kakarichoo-ga itta-no? using-is-Aff supervisor-Nom said-QM ‘What kind of computer did the supervisor say the director is using?’ (4) Senmu-ga donna-pasokon-o director-Nom what-kind-computer-Acc tukatteiru-ka kakarichoo-ga kiita-no? using-is-QM supervisor-Nom ask-QM ‘Did the supervisor ask what kind of computer the director is using?’ Conclusions from M&T • A wh-phrase is licensed by a Question Marker (QM). • A wh-phrase creates a prediction for a subsequent QM in the course of the processing of the sentence. • Readers try to posit the QM as soon as possible. Negative Polarity Items in Japanese English any, at all, a red cent … Japanese -sika, nanimo, sukosimo … ‘only’, ‘at all’ ‘at all’ John did not have any books.

However, if the prediction of negation takes place via NPI, the processing of a negative sentence will be easier in the NPI context than in the non-NPI context. NPI ... Neg... ... Neg... (7)a.

(f1(1,26)=2.46, p = 0.07, f2(1,23)=2.37, p= 0.1) The NPI condition is significantly faster than the non-NPI condition at region 5 (V-neg region).

(f1(1,26)= 4.96, p = 0.09 f2(1, 23)=5.03 p = 0.1) Conclusions 1. NPI triggers an expectation of negation. 2. Processing of a negative sentence is easier in the context in which Negation is predicted via NPI than in the context without any prediction of negation.
