Closed-class word selection was investigated by focusing on determiner production. Native speakers from three different languages named pictures of objects using determiner plus noun phrases (e.g., in French "la table" [thefeminineA table], while ignoring distractor determiners printed on the pictures (e.g., "le" [themasculine]. The target and distractor expressed either shared or different grammatical and nongrammatical features (gender, number, and definiteness). A gender-facilitation effect was observed and attributed to noun processing. Crucially, across five experiments, distractors that shared a feature with the target determiner never resulted in longer naming latencies than distractors that were more different. These results indicate that activating related candidates is not detrimental for determiner retrieval, suggesting a noncompetitive mechanism of closed-class word selection.

This article studies the monotonicity behavior of plural determinersthat quantify over collections. Following previous work, we describe thecollective interpretation of determiners such as all, some andmost using generalized quantifiers of a higher type that areobtained systematically by applying a type shifting operator to thestandard meanings of determiners in Generalized Quantifier Theory. Twoprocesses of counting and existential quantification thatappear with plural quantifiers are unified into a single determinerfitting operator, which, unlike previous proposals, both capturesexistential quantification with plural determiners and respects theirmonotonicity properties. However, some previously unnoticed factsindicate that monotonicity of plural determiners is not always preservedwhen they apply to collective predicates. We show that the proposedoperator describes this behavior correctly, and characterize themonotonicity of the collective determiners it derives. It is proved thatdeterminer fitting always preserves monotonicity properties ofdeterminers in their second argument, but monotonicity in the firstargument of a determiner is preserved if and only if it is monotonic inthe same direction in the second argument. We argue that this asymmetryfollows from the conservativity of generalized quantifiers innatural language.  相似文献

Determiner selection requires the retrieval of the noun's syntactic features (e.g., gender) and sometimes of its phonological features. Miozzo and Caramazza (1999) argued that the selection of determiners in Germanic languages is more straightforward than in Romance languages because it is not dependent on the phonological properties of the following word. In the present study, we used the picture–word interference paradigm to investigate the dependency of the determiner on the noun's features in French. In 3 experiments, we found a gender congruency effect at +200 stimulus onset asynchrony (SOA), indicating that participants were slower to produce the name of a picture (determiner + noun) when the picture–word pair was incongruent in gender than when it was congruent. We failed to replicate this effect at 0 SOA, in line with previous studies (Alario & Caramazza, 2002). Our results suggest that the features involved in determiner selection are not language specific but rather are specific to the determiner system.

针对深基坑变形RBF神经网络监测模型,根据在开挖期间深基坑土体的变形特性,利用遗传蠕变来构造输入因子,鉴于目前在中心选择方面没有严格的理论依据,并充分考虑输入因子的特点,提出了一种选择中心的经验方法,经过实例检验,该方法选择中心可以使模型得到较好的预测效果。  相似文献
