With the event-related potential (ERP) technique, this study examined whether participants with interpreting experience may adapt to the conflicting environment of a Flanker task more efficiently than non-interpreter bilinguals with the progression of the task (i.e., from the first to the second half trials). Our results showed that the interpreter group showed better conflict resolution (i.e., a lower error rate) despite being less active in early attentional processing (i.e., less negative overall N1 and N2 amplitudes). Second, both groups showed an adaptation effect in the second half trials compared with the first half, as reflected by less negative overall N2 amplitude and more positive overall P3 amplitude. More importantly, only the interpreter group showed an additional benefit in adaptation, as reflected by an earlier overall P3 peak latency in the second half trials.

Recent intracranial research has begun to map out the feature space associated with syntactic processes, but the field lacks a unified framework that can direct invasive neural analyses. This article proposes a neurocomputational architecture for syntax, termed ROSE (Representation, Operation, Structure, Encoding). Under ROSE, the basic data structures of syntax are atomic features, types of mental representations (R), and are coded at the single-unit and ensemble level. Operations (O) transforming these units into manipulable objects accessible to subsequent structure-building levels are coded via high frequency broadband γ activity. Low frequency synchronization and cross-frequency coupling code for recursive structural inferences (S). Distinct forms of low frequency coupling encode these structures onto distinct workspaces (E). Causally connecting R to O is spike-phase/LFP coupling; connecting O to S is phase-amplitude coupling; connecting S to E are frontotemporal traveling oscillations.

The context is in this case response congruent, because application of the task instruction to the context would lead to the correct response. This study investigates the time-course of response congruence effects in speech production using event-related potentials (ERPs). Participants overtly named target words that were overlaid on context pictures with either their superordinate category level name or their associated function, while their response times and ERPs were recorded. Behavioural results replicate the facilitating effect of response congruence. The ERP results showed that the N2 was larger for a response incongruent than congruent context, and this effect correlated with the behavioural pattern of results. This key finding suggests that response incongruence is associated with a conflict-monitoring response which drives the behavioural effect. Further, N400 amplitude was not modulated by response congruence, showing that its effect appears confined to the conceptualisation phase. Finally, P3 modulations mirrored those in RTs, but unlike the N2 effect, they did not correlate with RTs. This suggests that, although the facilitating effect of response congruence is confined to the conceptualisation phase of speech production, response incongruent representations may remain active during later processing stages, or that this late effect of response congruence reflects conflict resolve.

Adjectives are used in two different ways in English: <em>attributively</em>, to modify a noun (<em>the hungry dog</em>); or <em>predicatively</em>, after a verb (<em>the dog is hungry</em>). Attributive adjectives have a more complex grammatical structure than predicative adjectives, and may therefore be particularly prone to disruption in individuals with grammatical impairments. We investigated adjective production in three subtypes of primary progressive aphasia (PPA: agrammatic, semantic, logopenic), as well as in agrammatic stroke aphasia and a group of healthy control participants. Participants produced narratives based on picture books, and we coded every adjective they produced for its syntactic structure. Compared to healthy controls, the two agrammatic groups, but not the other two patient groups, produced significantly fewer attributive adjectives per sentence. All four patient groups were similar to controls for their rate of predicative adjective production. In addition, we found a significant correlation in the agrammatic PPA participants between their rate of producing attributive adjectives and impaired production of sentences with complex syntactic structure (subject cleft sentences like <em>It was the boy that chased the girl</em>); no such correlation was found for predicative adjectives. Irrespective of structure, we examined the lexical characteristics of the adjectives that were produced, including length, frequency, semantic diversity and neighborhood density. Overall, the lexical characteristics of the produced adjectives were largely consistent with the language profile of each group. In sum, the results suggest that attributive adjectives present a particular challenge for individuals with agrammatic language production, and add a new dimension to the description of agrammatism. Our results further suggest that attributive adjectives may be a fruitful target for improved treatment and recovery of agrammatic language.</p></div>","PeriodicalId":50118,"journal":{"name":"Journal of Neurolinguistics","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92073569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a tone language such as Mandarin, pitch not only carries affective information but also serves to distinguish lexical meanings.

Thus, the present study aimed to (1) test whether left-hand muscle contractions that activate the right hemisphere's sensory-motor regions can boost metaphor comprehension in adolescents; (2) compare conventional and novel metaphor processing (with no muscle contractions) in adolescents and adults. For the first goal, 83 adolescents between the ages of 14–16 squeezed a rubber ball with either their right hands, left hands, or not at all (control group) while presented with two-word expressions of four types: literal expressions, conventional metaphors, novel metaphors, and unrelated expressions. Results showed that left-hand muscle contractions led to more accurate processing of literal expressions and conventional and novel metaphors. However, the over-activation of the right hemisphere led to a decreased ability to process unrelated expressions. For the second goal, the adolescent control group was compared with an adult group of participants. Results revealed that despite a general disadvantage in language processing (including conventional metaphors), adolescents were more accurate in processing novel metaphors. Our findings suggest that adolescents' left lateralization for language is not yet established, resulting in over-reliance on coarse semantic coding.
