A common characteristic of subject-predicate agreement errors (usually termed attraction errors) in complex noun phrases is an asymmetrical pattern of error distribution, depending on the inflectional state of the nouns comprising the complex noun phrase. That is, attraction is most likely to occur when the head noun is the morphologically…

Previous evidence suggests that when speakers produce sentences from memory or as picture descriptions, their choices of sentence structure are influenced by how easy it is to retrieve sentence material (accessibility). Three experiments assessed whether this pattern holds in naturalistic, interactive dialogue. Pairs of speakers took turns asking…

In this paper we examine the way disjunctive choices work in conversational context. We focus on disjunctive deontic rules, such as "you must either submit an essay or attend an exam". According to the Gricean "maxim of orderliness", a derivative of the "maxim of manner", people should interpret the first-mentioned…

Seven experiments using self-paced reading and eyetracking suggest that omitting the middle verb in a double centre embedding leads to easier processing in English but leads to greater difficulty in German. One commonly accepted explanation for the English pattern--based on data from offline acceptability ratings and due to Gibson and Thomas…

Relative clauses have been implicated alternately as a strength and a weakness in the language of people with Williams Syndrome (WS). To clarify the facts, an elicited production test was administered to 10 people with WS (age 10-16 years), 10 typically developing children (age 4-7 years), and 12 typically developing adults. Nearly every WS…

We assessed whether and under what conditions noncanonical agreement patterns occur in Russian, with the goal of understanding the factors involved in normal agreement. Russian is a morphosyntactically rich language in which agreement involves features for number, gender, and case. If consistent, overt specification of number and gender agreement…

Two eye-tracking experiments and two self-paced reading experiments investigated processing of sentences containing reduced relative clauses. Processing of a reduced relative is facilitated when it is preceded by a sentence that has the same syntactic structure, as long as the preceding sentence contains the same critical verb as the target…

The current study examines whether young and older adults have similar preferences for animate-subject and active sentences, and for using the order of activation of a verb's arguments to determine sentence structure. Ninety-six participants produced sentences in response to three-word stimuli that included a verb and two nouns differing in…

This study examines sentence-level language abilities of amnesic H.M. to test competing theoretical conceptions of relations between language and memory. We present 11 new sources of experimental evidence indicating deficits in H.M's comprehension and production of non-cliche sentences. Contrary to recent claims that H.M.'s comprehension is…

In order to study the role of working memory in sentence formulation, we elicited errors of subject-verb agreement in spoken sentence completion, while speakers did or did not maintain an extrinsic memory load (a word list). We compared participants with low and high speaking spans (a measure of verbal working memory for sentence production). As…
