Cross-linguistic evidence for memory storage costs in filler-gap dependencies with wh-adjuncts

This study investigates processing of interrogative filler-gap dependencies in which the filler integration site or gap is not directly subcategorized by the verb. This is the case when the wh-filler is a structural adjunct such as how or when rather than subject or object. Two self-paced reading experiments in English and Slovenian provide converging cross-linguistic evidence that wh-adjuncts elicit a kind of memory storage cost similar to that previously shown in the literature for wh-arguments. Experiment 1 investigates the storage costs elicited by the adjunct when in Slovenian, and Experiment 2 the storage costs elicited by how quickly and why in English. The results support the class of theories of storage costs based on the metric in terms of incomplete phrase structure rules or incomplete syntactic head predictions. We also demonstrate that the endpoint of the storage cost for a wh-adjunct filler provides valuable processing evidence for its base structural position, the identification of which remains a rather murky issue in current grammatical research.

Two (non-)islands in Slovenian : A study in experimental syntax

Abstract There exists a controversy in the literature and among the speakers of Slovenian concerning the grammaticality of wh-island and subject island constructions in this language. We conducted an acceptability rating study of wh-islands and subject islands in Slovenian, using the factorial definition of island. This definition provides for a possibility to isolate a true island effect while controlling for two complexity factors that potentially interfere in speakers’ evaluation of the relevant sentences: the length of the respective movement dependency and the presence of an island structure itself. We found that (i) Slovenian speakers do judge the wh-island sentences worse than the respective controls, but the observed degradation cannot be attributed to a true island effect; (ii) subject extraction out of a wh-island leads to a so called reverse island effect whereby the acceptability is higher than expected even if the above two complexity factors are taken into consideration; and (iii) speakers are sensitive to the subject island effect, as predicted by the mainstream theories of syntactic locality. The results of our study contribute to establishing a solid empirical base for further theoretical investigations of the island effects and raise new questions about the role of processing factors in speakers’ evaluations of island constructions.

Countability, agreement and the loss of the dual in Russian

In this work we investigate the internal syntax and semantics of quantifier phrases (QP) involving cardinal numerals. Concentrating on a set of previously documented puzzles concerning Case and number agreement within the numeral phrase in Russian, we argue that these agreement patterns follow naturally if one recognizes three structural layers in a numeral-based QP: the countability layer, the number layer and the quantificational layer. Our central theoretical claim is that the countability layer is implemented as a (pseudo-)classifier structure whose morphological manifestation obeys a principle of syntactic ‘visibility’. Our specific claim for Russian is that, diachronically, this countability layer has emerged as a result of the loss of the dual number in the course of transition between Old and Modern Russian. We strengthen our conclusions with psycholinguistic evidence from a sentence completion study that tests Russian speakers’ sensitivity to the countability layer.

Agreement errors and structural distance: A corpus study of Bulgarian

In this work we address the phenomenon of substitution of the special “count form” suffix of masculine non-person nouns in Bulgarian numeral phrases for a simple plural morpheme. This substitution phenomenon is observed in everyday speech and writing and is noted by traditional Bulgarian grammarians. We propose to treat this phenomenon on a par with agreement errors previously investigated in the language production literature on English (e.g. “The editor of the books are...”) and on the Romance languages. We conducted a corpus study of agreement substitution errors in Bulgarian, the results of which support the psycholinguistic theories maintaining, in particular, that structural hierarchy is relevant for the computation of agreement in language production.
