This paper presents the results of a study of syntactically based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control participants. We measured off-line, end-of-sentence, performance (accuracy and reaction time) in two tasks that require comprehension--enactment and…

Although the effect of acoustic cues on speech segmentation has been extensively investigated, the role of higher order information (e.g., syntax) has received less attention. Here, the authors examined whether syntactic expectations based on subject-verb agreement have an effect on segmentation and whether they do so despite conflicting acoustic…

In five experiments, participants first read grammatical sentences of English and later rated identical, structurally similar, or novel sentences for grammatical acceptability. The experimental method was modeled after ''mere exposure'' and artificial grammar learning paradigms in which preference ratings are enhanced by prior experience with the…

Background: Language development is generally viewed as a multifactorial process. There are increasing indications that this similarly holds for the problematic language development process. Aims: A population of 97 young Dutch children with specific language impairment (SLI) was followed over a 2-year period to provide additional evidence for the…

This study investigates learners' knowledge of word classes (i.e. noun, verb, adjective) in their second language (L2). Although some L2 studies have examined the problem of word class indirectly through a focus on vocabulary and the teaching of derivational morphology (Morin, 2003, 2006; Schmitt & Zimmerman, 2002), little is known about learners'…

A classifier which is capable of distinguishing a syntactically well formed sentence from a syntactically ill formed one has the potential to be useful in an L2 language-learning context. In this article, we describe a classifier which classifies English sentences as either well formed or ill formed using information gleaned from three different…

Tasks have received increased attention in SLA research for the past decade, as has the role of focus on form. However, few empirical studies have investigated the relationship among tasks, focus-on-form techniques, and second language (L2) learning outcomes. To help address this gap, the present study examined how the task variable +/- contextual…

Children with unilateral pre- or perinatal brain injury (BI) show remarkable plasticity for language learning. Previous work highlights the important role that lesion characteristics play in explaining individual variation in plasticity in the language development of children with BI. The current study examines whether the linguistic input that…

Unlike English, Standard Arabic has two forms of subject pronouns: Independent such as "?na" ("I"), and a pronominal suffix that is an integral part of the verb such as "katab-tu" ("I wrote"). Independent subject pronouns are commonly used in nominal sentences, not verbal sentences. Use of independent…

Matching-to-sample and sequence training procedures were used to develop responding to stimulus classes that were considered analogous to 3 aspects of verbal behavior: identifying synonyms and parts of speech,and using syntax. Matching-to-sample procedures were used to train 12 paired associates from among 24 stimuli. These pairs were analogous to…

This study analyses a case of parallel grammaticalization in five genetically related languages, with a lexical source meaning "person" developing to a grammatical function of reflexive marking. Although not typologically unusual, this case is special because, in spite of the overall parallelism, the resulting reflexive markers are located in…

This article presents a study examining how narrative structure and narrative complexity might influence the performance of second language learners. Forty learners of English in London and sixty learners in Teheran were asked to retell cartoon stories from picture prompts. Each performed two of four narrative tasks that had different degrees of…

Signaling noncomprehension of the spoken messages of others was examined for youth with fragile X or Down syndrome in comparison with each other and nonverbal MA-matched typically developing children. A direction-following task was used in which some of the directions were inadequate. Both syndrome groups signaled noncomprehension less often than…

Background: This study investigated the relationship between phonological and syntactic disorders of French-speaking children with specific language impairment in production. Aims: To compare three theories (pure phonological theory, surface theory, and mapping theory) of language developmental disorders, all of which view phonological…

As students transition from primary to intermediate grades, the kind of materials that they are expected to read and write become more heavily dominated by expository texts. Expository texts contain grammatical patterns that are distinct from those used in primary-grade storybooks. These linguistic features pose new comprehension challenges for…
