The comprehension of relative clauses in Mandarin Children with suspected specific language impairment

This paper investigates the comprehension of Relative Clauses (RCs) in 15 Mandarin children with suspected Specific Language Impairment (SLI) (aged between 4; 5 and 6; 0) and 29 typically developing (TD) controls. Results from a Character Picture Matching Task indicate that (i) the subject RC was better understood than the object RC in children with SLI, but there was no asymmetry in the comprehension of the two RCs in TD children; (ii) the performance of children with SLI was significantly worse than that of their TD peers; (iii) children with SLI were prone to committing thematic role reversal errors and middle errors. In order to overcome the shortcomings of previous accounts, we therefore put forward the Edge Feature Underspecification Hypothesis, which can not only explain the asymmetry of comprehension seen in children with SLI but also shed light on the nature of errors committed by them in the task.

Long-term memory predictors of adult language learning at the interface between syntactic form and meaning

Recent neurocognitive models of second language learning have posited specific roles for declarative and procedural memory in the processing of novel linguistic stimuli. Pursuing this line of investigation, the present study examined the role of declarative and procedural memory abilities in the early stages of adult comprehension of sentences in a miniature language with natural language characteristics (BrocantoJ). Thirty-six native Italian young adults were aurally exposed to BrocantoJ in the context of a computer game over three sessions on consecutive days. Following vocabulary training and passive exposure, participants were asked to perform game moves described by aural sentences in the language. Game trials differed with respect to the information the visual context offered. In part of the trials processing of relationships between grammatical properties of the language (word order and morphological case marking) and noun semantics (thematic role) was necessary in order reach an accurate outcome, whereas in others nongrammatical contextual cues were sufficient. Declarative and procedural learning abilities were respectively indexed by visual and verbal declarative memory measures and by a measure of visual implicit sequence learning. Overall, the results indicated a substantial role of declarative learning ability in the early stages of sentence comprehension, thus confirming theoretical predictions and the findings of previous similar studies in miniature artificial language paradigms. However, for trials that specifically probed the learning of relationships between morphosyntax and semantics, a positive interaction between declarative and procedural learning ability also emerged, indicating the cooperative engagement of both types of learning abilities in the processing of relationships between ruled-based grammar and interpretation in the early stages of exposure to a new language in adults.

Thematic role assignment in non-default verb classes: A cross-linguistic comparison of English and German

The influence of sentential cues (such as animacy and word order) on thematic role interpretation differs as a function of language (MacWhinney et al. 1984). However, existing cross-linguistic research has typically focused on transitive sentences involving agents, and interpretation of non-default verb classes is less well understood. Here, we compared the way in which English and German native speakers – languages known to differ in the cue prominence of animacy and word order – assign thematic roles. We compared their interpretation of sentences containing either default (agent-subject) or non-default (experiencer-subject) verb classes. Animacy of the two noun phrases in a sentence was either animate-inanimate and plausible (e.g. “The men will devour the meals...”) or inanimate-animate and implausible in English (e.g. “The meals will devour the men…”). We examined role assignment by probing for either the actor or undergoer of the sentence. Mixed effects modelling revealed that role assignment was significantly influenced by noun animacy, verb class, question type, and language. Results are interpreted within the Competition Model framework (Bates et al. 1982; MacWhinney et al. 1984), and show that English speakers predominantly relied on word order for thematic role assignment. German speakers relied on word order to a comparatively lesser degree, with animacy a prominent cue. Non-default verbs (experiencer-subject) promoted a non-default comprehension strategy regarding the prominence of sentential cues, particularly in German. Intriguingly, responses were modulated by the probe task, with undergoer probes promoting object-initial interpretations, particularly for German speakers. This suggests that task focus may retroactively influence sentence interpretation.

Interpretation preferences in contexts with three antecedents: examining the role of prominence in German pronouns

This paper focuses on the relational notion of prominence, in which entities of equal type are ranked according to certain prominence-lending features. In German two demonstrative forms, “der” and “dieser”, can function like personal pronouns in English. It has been proposed that processing “der” involves computing a prominence hierarchy of the prior referents, and excluding the referent with the highest prominence rank. The demonstrative “dieser” has not been extensively tested. In the current study, personal and demonstrative pronominal forms were investigated following ditransitive contexts, where three potential antecedents are available, in two rating experiments. The personal pronoun showed flexibility in that it received equally high ratings for all three antecedents in canonical configurations. The ratings for dieser followed a graded sensitivity to thematic role prominence, with lowest scores when referring to prominent antecedents (agents) and the highest scores for the least prominent antecedents (patients), with scores for the medium prominence candidate (recipients) differing from both. Der followed a similar but not identical pattern, with a less marked difference between lower prominence candidates. Positional information also has a strong influence on demonstratives. In sum, final interpretation is sensitive to fine-grained differences in prominence hierarchies.

The Influence of Auditory Attention on Rhythmic Speech Tracking: Implications for Studies of Unresponsive Patients

Language comprehension relies on integrating words into progressively more complex structures, like phrases and sentences. This hierarchical structure-building is reflected in rhythmic neural activity across multiple timescales in E/MEG in healthy, awake participants. However, recent studies have shown evidence for this “cortical tracking” of higher-level linguistic structures also in a proportion of unresponsive patients. What does this tell us about these patients’ residual levels of cognition and consciousness? Must the listener direct their attention toward higher level speech structures to exhibit cortical tracking, and would selective attention across levels of the hierarchy influence the expression of these rhythms? We investigated these questions in an EEG study of 72 healthy human volunteers listening to streams of monosyllabic isochronous English words that were either unrelated (scrambled condition) or composed of four-word-sequences building meaningful sentences (sentential condition). Importantly, there were no physical cues between four-word-sentences. Rather, boundaries were marked by syntactic structure and thematic role assignment. Participants were divided into three attention groups: from passive listening (passive group) to attending to individual words (word group) or sentences (sentence group). The passive and word groups were initially naïve to the sentential stimulus structure, while the sentence group was not. We found significant tracking at word- and sentence rate across all three groups, with sentence tracking linked to left middle temporal gyrus and right superior temporal gyrus. Goal-directed attention to words did not enhance word-rate-tracking, suggesting that word tracking here reflects largely automatic mechanisms, as was shown for tracking at the syllable-rate before. Importantly, goal-directed attention to sentences relative to words significantly increased sentence-rate-tracking over left inferior frontal gyrus. This attentional modulation of rhythmic EEG activity at the sentential rate highlights the role of attention in integrating individual words into complex linguistic structures. Nevertheless, given the presence of high-level cortical tracking under conditions of lower attentional effort, our findings underline the suitability of the paradigm in its clinical application in patients after brain injury. The neural dissociation between passive tracking of sentences and directed attention to sentences provides a potential means to further characterise the cognitive state of each unresponsive patient.

The plastic of clothing and the construction of visual communication and interaction: a semiotic examination of the eighteenth-century French dress

The article presents an account of the visual relations created by garments through their plastic formants, examining the role played by form, material, and composition in creating body hierarchies that produce prescribed behaviors between different subjects. The work dissects the concept of thematic role from the Greimasian theory, investigating the manners in which an eighteenth-century wedding dress presents the chaining of programs governing materials, garments, and the body in the production of narrative interactions between subjects. The work utilizes a combination of Greimas’ method with the Visual Semiotics continued by Floch and Oliveira, as well as Hammad’s Semiotics of Space which permit the exam of optical relations created in the body through its clothing – relations that can be read both as manifesting values that are historically and socially determined, or in the act of apprehension of an object. The eighteenth century provides a type of “original” case, whose results are pertinent to a broader study of the relations between body and dress: the work concludes with the understanding that Fashion changes through the transit of values and roles invested in the body and dress – a set of changes closely linked to the construction of social roles.

Fundamental Structures with Reflexive Pronoun in Dative in Romanian

This article focuses on the problem of the functioning of the reflexive pronoun in dative modifying the verb. Based on a substantial corpus, the article refers to the delimitation of its functions, values and nuances, as well as the various fundamental structures in which it appears. Three constructions with their afferent structures are described, from which it appears that the reflexive dative works in two ways: 1) the subcategorization of the verb, receiving the thematic role of recipient or beneficiary and syntactic function of indirect object and 2) the double subordination - to the verb and to a noun in the structure. That is, it does not occupy a position of subcategorization of the verb, but acquires a possessive meaning from this noun and fulfills the function of possessive object, a function without a thematic role.

Thematic reanalysis in the left posterior parietal sulcus: A TMS study

Understanding who does what to whom is at the core of sentence comprehension. The actors that contribute to the verb meaning are labeled thematic roles. We used Transcranial Magnetic Stimulation (TMS) to verify the possible impact of verb semantics on the thematic role encoding process that has been shown to involve the posterior portion of the left posterior parietal sulcus (PPS; Finocchiaro et al., 2015). Sixteen participants underwent TMS and SHAM sessions while performing an ℌagent-decisionℍ task, in which they had to decide by key press which of the two arguments was the agent of visually presented sentences or pseudo-sentences. (Pseudo)sentences were all reversible and were presented in the active or passive diathesis. Double pulse TMS was delivered to the posterior part of the IPS in an event-related fashion, at two different time windows: 200-400 msec (T1) or 600-800 msec (T2) time-locked to the presentation of the (pseudo)sentence. Results showed that TMS increased accuracy on passive sentences and pseudo-sentences as compared to active sentences and to the baseline, SHAM condition. Indeed, the presence of a verb with a full semantic representation was not a necessary precondition for the TMS-induced facilitation of passive (pseudo)sentences. Stimulation timing had no effect on accuracy for sentences vs. pseudo-sentences. These observations support the idea that the posterior parietal site is recruited when the correct interpretation of a sentence requires reanalysis of temporarily encoded thematic roles (as in reversible passive sentences) even when the verb is not an entry in the lexicon and hence does not have a semantic representation. Results are consistent with previous evidence and deserve further investigation in larger experimental samples. Increasing the number and variety of stimulus sentences, and administering TMS to additional control sites will be key to further articulate the conclusions allowed by these initial findings.
