PurposeGrammatical encoding (GE) is impaired in agrammatic aphasia; however, the nature of such deficits remains unclear. We examined grammatical planning units during real-time sentence production in speakers with agrammatic aphasia and control speakers, testing two competing models of GE. We queried whether speakers with agrammatic aphasia produce sentences word by word without advanced planning or whether hierarchical syntactic structure (i.e., verb argument structure; VAS) is encoded as part of the advanced planning unit.MethodExperiment 1 examined production of sentences with a predefined structure (i.e., “The A and the B are above the C”) using eye tracking. Experiment 2 tested production of transitive and unaccusative sentences without a predefined sentence structure in a verb-priming study.ResultsIn Experiment 1, both speakers with agrammatic aphasia and young and age-matched control speakers used word-by-word strategies, selecting the first lemma (noun A) only prior to speech onset. However, in Experiment 2, unlike controls, speakers with agrammatic aphasia preplanned transitive and unaccusative sentences, encoding VAS before speech onset.ConclusionsSpeakers with agrammatic aphasia show incremental, word-by-word production for structurally simple sentences, requiring retrieval of multiple noun lemmas. However, when sentences involve functional (thematic to grammatical) structure building, advanced planning strategies (i.e., VAS encoding) are used. This early use of hierarchical syntactic information may provide a scaffold for impaired GE in agrammatism.

This paper is aimed to investigate the syntactic structure of deaf students of Brawijaya Universirty. Syntactic structure which focuses on this discussion is the ability to recognize the sentence structure produced by deaf students. This study basically focuses on the language produced by deaf students of Brawijaya University in form of narrative writing. The narrative writing is written in Indonesian language. I chose Indonesian language as the language recourse, because the primary language of deaf students is Indonesian.This study uses descriptive qualitative research because this research basically aimed at describing the data in the form written text. The participant of this research is five deaf students who are classified into mild and moderate hearing loss. In term of analyzing the data, we concern on the three aspects of sentence structure. Those are: types of sentence, the presence of Subject and Verb in a sentence and the presence of Object for transitive verb.The finding indicates that the deaf students of Brawijaya University are able to write both simple sentences and compound sentence. They are also capable to write transitive verb which is followed by the object well. Yet, they are less in writing the passive voice form. Moreover, the data shows that different time durations of writing create a different number of words produced by them. Different deaf classification can provide different significance to a number of sentences produced by them.

Syntactic Features

The most serious recent work on the theory of coordination has probably been done in terms of three theories of grammatical structure: Generalized Phrase Structure Grammar (GPSG–see especially Gazdar, 1981; Gazdaret al., 1982; 1985; Saget al., 1985; Schachter & Mordechay, 1983), Categorial Grammar (CG–see especially Steedman, 1985; Dowty, 1985) and Transformational Grammar (TG–notably Williams, 1978, 1981; Neijt, 1979; van Oirsouw, 1985, 1987). Each of these approaches is different in important respects: for instance, according to whether or not they allow deletion rules, and according to the kinds of information which they allow to be encoded in syntactic features. However, behind these differences lies an important similarity: in each case the theory concerned makes two assumptions about grammatical structure in general (i.e. about all structures, including coordinate ones):I The basic syntagmatic relations in sentence-structure are part-whole relations (consituent structure) and temporal order; note that this is true whether or not syntactic structure is seen as a ‘projection’ of lexical properties, since these lexical properies are themselves defined in terms of constituent structure and temporal order.

Background: The spontaneous and narrative language of Kiswahili agrammatic aphasic and non-brain-damaged speakers was analysed. The bilingual participants were also tested in English to enable comparisons of verb production in the two languages. The significance of this study was to characterise bilingual Kiswahili-English spontaneous agrammatic output. This was done by describing Kiswahili-English bilingual output data with a specific focus on the production of verbs. The description involves comparison of verb and argument production in Kiswahili and English. Methods and procedures: The participants recruited for this study were drawn from two groups of participants (six non-fluent aphasic/agrammatic speakers and six non-braindamaged). From each participant, a sample of spontaneous output was tape-recorded in English and Kiswahili based on the description and narration of the Flood rescue picture’ and the ‘Cookie theft picture’. The data elicited were compared for each subject and between the participants and relevant verb parameters have been analysed. The variables that were studied included mean length of utterance (MLU), inflectional errors, verb tokens and types, copulas and auxiliaries. Further, all verbs produced were classified as per their argument structure. Results: The results from English data supported previous findings on agrammatic output. The agrammatic participants produced utterances with shorter MLU and simpler sentence structure. However, Kiswahili data surprisingly showed reversed results, with agrammatic speakers producing longer utterances than non-brain-damaged (NBD) controls. The results also revealed selective impairment in some agrammatic speakers who made inflectional errors. The verb argument structure showed contrasting results, with agrammatic speakers preferring transitive verbs whilst the NBD speakers used more intransitive verbs.Conclusions: The study attempts for the first time to characterise English-Kiswahili bilingual spontaneous and narrative output. A quantitative analysis of verb and argument production is conducted. The results of the English data are consistent with those in the literature; agrammatic speakers produce utterances with shorter MLU and simpler sentence structure. However, Kiswahili data reveals a surprisingly reversed pattern most notably with respect to MLU with agrammatics producing longer utterances than NBD controls. Argument structure analysis revealed that agrammatics used more transitive verbs than intransitives.

Linguistic analyses suggest that there are two types of intransitive verbs: unaccusatives, whose sole argument is a patient or theme (e.g., fall), and unergatives, whose sole argument is an agent (e.g., jump). 1 Past psycholinguistic experiments suggest that this distinction affects how sentences are processed: for example, it modulates both comprehension processes ( Bever and Sanz 1997 , Friedmann et al. 2008 ) and production processes ( Kegl 1995 , Kim 2006 , M. Lee and Thompson 2004 , J. Lee and Thompson 2011 , McAllister et al. 2009 ). Given this body of evidence, it is reasonable to assume, as we do here, that this distinction is directly relevant to psycholinguistic theorizing. However, especially in production, exactly how this distinction affects processing is unknown, beyond the suggestion that unaccusatives somehow involve more complex processing than unergatives (see J. Lee and Thompson 2011 ). Here we examine how real-time planning processes in production differ for unaccusatives and unergatives. We build on previous studies on lookahead effects in sentence planning that show that verbs are planned before a deep object is uttered but not before a deep subject is uttered ( Momma, Slevc, and Phillips 2015 , 2016 ). (We use terms like deep subject in a theory-neutral fashion, with no intended commitment to a specific syntactic encoding.) This line of research sheds light on the broader issue of how the theory of argument structure relates to sentence production.

Predicate Argument Structure

This book presents a detailed descriptive and theoretical examination of predicate-argument structure in Niuean, a Polynesian language within the Oceanic branch of the Austronesian family, spoken mainly on the Pacific island of Niue and in New Zealand. Niuean has VSO word order and an ergative case-marking system, both of which raise questions for a subject-predicate view of sentence structure. Working within a broadly Minimalist framework, this volume develops an analysis in which syntactic arguments are not merged locally to their thematic sources, but instead are merged high, above an inverted extended predicate which serves syntactically as the Niuean verb, later undergoing movement into the left periphery of the clause. The thematically lowest argument merges as an absolutive inner subject, with higher arguments merging as applicatives. The proposal relates Niuean word order and ergativity to its isolating morphology, by equating the absence of inflection with the absence of IP in Niuean, which impacts many aspects of its grammar. As well as developing a novel analysis of clause and argument structure, word order, ergative case, and theta role assignment, the volume argues for an expanded understanding of subjecthood. Throughout the volume, many other topics are also treated, such as noun incorporation, word formation, the parallel internal structure of predicates and arguments, null arguments, displacement typology, the role of determiners, and the structure of the left periphery.

This paper provides a unified syntactic account of the distribution of Englishhavein causative constructions (e.g.John had Mary read a book) and experiencer constructions (e.g.John had the student walk out of his classroom). It is argued thathaveis realized in the context of anapplicative head(Appl) and an event-introducer v, regardless of the type of v.Haveis spelled out in the causative when Appl merges under vCAUSE, and in the experiencer construction when Appl merges under vBE. This proposal is extended tohavein possessive constructions (e.g.John has a hat/a brother):haveis realized in the context of vBEand Appl. The proposed account provides empirical evidence for expanding the distribution of Appl: (i) a causative can take ApplP as a complement, which was absent in Pylkkänen's (2008) typological classification, and (ii) Appl can merge above Voice, contrary to Pylkkänen's analysis in which Appl is argued to always merge below VoiceP, never above. Moreover, the proposed account supports the theoretical claim that argument structure is licensed by functional syntactic structure; in particular, it shows that the relevant functional heads are not aspectual heads, but Appl and v.

This chapter offers a review of experimental evidence about the role of the speaker’s attention in the choice of syntactic structure and the corresponding word order during sentence production. Here, we describe how the speaker’s syntactic choices reflect the regular mapping mechanism that reflects the features of the described event in the produced sentence. One of the most important event parameters that the speaker considers is the changing salience status of the event’s referents. This chapter summarizes current theoretical debate about the interplay between attention and sentence production mechanisms. Finally, it reviews the corresponding experimental evidence from languages with both restricted and flexible word orders.

Classification Tasks

The syntactic structure of sentences in a document substantially informs about its authorial writing style. Sentence representation learning has been widely explored in recent years and it has been shown that it improves the generalization of different downstream tasks across many domains. Even though utilizing probing methods in several studies suggests that these learned contextual representations implicitly encode some amount of syntax, explicit syntactic information further improves the performance of deep neural models in the domain of authorship attribution. These observations have motivated us to investigate the explicit representation learning of syntactic structure of sentences. In this article, we propose a self-supervised framework for learning structural representations of sentences. The self-supervised network contains two components; a lexical sub-network and a syntactic sub-network which take the sequence of words and their corresponding structural labels as the input, respectively. Due to the n -to-1 mapping of words to their structural labels, each word will be embedded into a vector representation which mainly carries structural information. We evaluate the learned structural representations of sentences using different probing tasks, and subsequently utilize them in the authorship attribution task. Our experimental results indicate that the structural embeddings significantly improve the classification tasks when concatenated with the existing pre-trained word embeddings.

This article describes what is known about the adult end-state, namely, that the adult listener recovers the syntactic structure of an utterance in real-time via interactive probabilistic parsing procedures. It examines evidence indicating that similar mechanisms are at work quite early during language learning, such that infants and toddlers attempt to parse the speech stream probabilistically. In the case of learning, though, the parsing is in aid of discovering relevant lower-level linguistic formatives such as syllables and words. Experimental observations about child sentence-processing abilities are still quite sparse, owing in large part to the difficulty in applying adult experimental procedures to child participants; reaction time, reading, and linguistic judgement methods have all have been attempted with children. The article discusses real-time sentence processing in adults, experimental exploration of child sentence processing, eye movements during listening and the kindergarten-path effect, verb biases in syntactic ambiguity resolution, prosody and lexical biases in child parsing, parsing development in a head-final language, and the place of comprehension in a theory of language acquisition.
