Syntactic and Story Structure Complexity in the Narratives of High- and Low-Language Ability Children with Autism Spectrum Disorder.

Although language impairment is commonly associated with the autism spectrum disorder (ASD), the Diagnostic Statistical Manual no longer includes language impairment as a necessary component of an ASD diagnosis (American Psychiatric Association, 2013). However, children with ASD and no comorbid intellectual disability struggle with some aspects of language whose precise nature is still outstanding. Narratives have been extensively used as a tool to examine lexical and syntactic abilities, as well as pragmatic skills in children with ASD. This study contributes to this literature by investigating the narrative skills of 30 Greek-speaking children with ASD and normal non-verbal IQ, 16 with language skills in the upper end of the normal range (ASD-HL), and 14 in the lower end of the normal range (ASD-LL). The control group consisted of 15 age-matched typically-developing (TD) children. Narrative performance was measured in terms of both microstructural and macrostructural properties. Microstructural properties included lexical and syntactic measures of complexity such as subordinate vs. coordinate clauses and types of subordinate clauses. Macrostructure was measured in terms of the diversity in the use of internal state terms (ISTs) and story structure complexity, i.e., children's ability to produce important units of information that involve the setting, characters, events, and outcomes of the story, as well as the characters' thoughts and feelings. The findings demonstrate that high language ability and syntactic complexity pattern together in ASD children's narrative performance and that language ability compensates for autistic children's pragmatic deficit associated with the production of Theory of Mind-related ISTs. Nevertheless, both groups of children with ASD (high and low language ability) scored lower than the TD controls in the production of Theory of Mind-unrelated ISTs, modifier clauses and story structure complexity

Exploiting Deep Semantics and Compositionality of Natural Language for Human-Robot-Interaction

We develop a natural language interface for human robot interaction that implements reasoning about deep semantics in natural language. To realize the required deep analysis, we employ methods from cognitive linguistics, namely the modular and compositional framework of Embodied Construction Grammar (ECG) [Feldman, 2009]. Using ECG, robots are able to solve fine-grained reference resolution problems and other issues related to deep semantics and compositionality of natural language. This also includes verbal interaction with humans to clarify commands and queries that are too ambiguous to be executed safely. We implement our NLU framework as a ROS package and present proof-of-concept scenarios with different robots, as well as a survey on the state of the art

Reason without much language

Language is more than a system used for interpersonal communication. Linguistic representations can also form a part of reasoning in other cognitive domains. However, it is unclear whether the role of language in non-verbal domains is a necessary one, or whether it represents an optional resource that is recruited under demanding or highly intentional processing conditions. The possible role of language in categorisation, belief reasoning, calculation and cross-domain integration is explored, together with the various sources of evidence that can inform debates on language–thought relationships. Evidence from comparative and developmental psychology, together with that from neuroscience and ‘virtual language impairment’ (verbal shadowing) suggests reduced or absent language resource can disrupt performance in non-verbal domains. Similarly results of some investigations of people with developmental or acquired language impairments suggest an association with broader cognitive impairment. However, there is a substantial and growing body of evidence from across experimental fields indicating autonomy between language and reasoning. Residual reasoning in the face of severe aphasia is described, together with possible objections to the evidence from aphasia informing language and thought debates

Subordination in Italian and English: implications for second language acquisition

Our study focuses on morpho-syntactic complexity, trying to identify the specific subordinated modalities of organizing and packaging information in a narration. This purpose will be achieved by combining the morpho-syntactic analysis with the type of contents that subordinate clauses convey with respect to the informational flux of textual structure (foreground vs. background alternation). A functionalist and enunciative framework is adopted. The following questions will be addressed: (1) which types of morpho-syntactic structures – main or subordinated, finite or non finite – are exploited to convey the subordinated contents selected? (2) do the informants tend to hierarchize the expressed contents? (3) which types of semantic and/or logical components (temporality, causality, etc.) are selected to be narrated and highlighted through subordination? We shall demonstrate that only the interaction of several factors – core morphological facts, interactional and discourse habits – can exhaustively explain the textual perspectives observed in our L1 and L2 data, with interesting consequences for second language acquisition

Modal Markers in Japanese: A Study of Learners’ Use before and after Study Abroad

Japanese discourse requires speakers to index, in a relatively explicit manner, their stance toward the propositional information as well as the hearer. This is done, among other things, by means of a grammaticalized set of modal markers. Although previous research suggests that the use of modal expressions by second language learners differs from that of native users, little is known about “typical” native or non-native behavior. This study aims (a) to delineate native and non-native usage by a quantitative examination of a broad range of Japanese modal categories, and qualitative analyses of a subset of potentially problematic categories among them, and (b) to identify possible developmental trajectories, by means of a longitudinal observation of learners’ verbal production before and after study abroad in Japan. We find that modal categories realized by non- transparent or non-salient markers (e.g., explanatory modality no da, or utterance modality sentence-final particles) pose particular challenges in spite of their relatively high availability in the input, and we discuss this finding in terms of processing constraints that arguably affect learners’ acquisition of the grammaticalized modal markers

Defining the Characteristics of Story Production of Autistic Children: A Multilevel Analysis

Several studies suggest that a valuable tool to examine linguistic skills in communication disorders is offered by procedures of narrative discourse assessment. Following this line of research, we present an exploratory study aimed to investigate storytelling abilities of autistic children to better define the characteristics of their story production. Participants included 41 autistic children and 41 children with typical development aged between 7.02 and 11.03 years matched on age, gender, level of formal education, intelligence quotient, working memory, attention skills, theory of mind, and phonological short-term memory. Narrative production was assessed by analysing the language samples obtained through the “Nest Story” description task. A multilevel analysis including micro- and macro-linguistic variables was adopted for narrative assessment. Group differences emerged on both micro- and macro-linguistic dimensions: autistic children produced narratives with more phonological errors and semantic paraphasias (microlinguistic variables) as well as more errors of global coherence and a fewer number of visible events and inferred events (macrolinguistic variables) than the control group.This study shows that even autistic children with adequate cognitive skills display several limitations in their narrative competence and that such weaknesses affect both micro- and macrolinguistic aspects of story production

Eye tracking sentences in language education

The present study reports and discusses the use of eye tracking qualitative data (static and dynamic gaze plots and heatmaps) in reading workshops in a middle school and in Generative Syntax and Sentence Processing courses at the undergraduate and graduate levels. Both endeavors take the sentential level as the proper object to be metacognitively explored in language education in order to develop innate science forming capacity and knowledge of language. In both projects non-discrepant qualitative eye tracking data collected and quantitatively analyzed in psycholinguistic studies carried out in LAPEX-UFRJ (Experimental Psycholinguistics Laboratory of the Federal University of Rio de Janeiro) were displayed to students as a point of departure, triggering discussions. Active, problem-solving based methodologies were employed with the objective of stimulating student participation. The article also discusses the importance of developing full literacy, epistemic vigilance and intellectual self-defense in an infodemic world.The present study reports and discusses the use of eye tracking qualitative data (static and dynamic gaze plots and heatmaps) in reading workshops in a middle school and in Generative Syntax and Sentence Processing courses at the undergraduate and graduate levels.
