Previous studies suggest that semantic concepts are characterized by high-dimensional neural representations and that language proficiency affects semantic processing. However, it is not clear whether language proficiency modulates the dimensional representations of semantic concepts at the neural level. To address this question, the present study adopted principal component analysis (PCA) and representational similarity analysis (RSA) to examine the differences in representational dimensionalities (RDs) and in semantic representations between words in highly proficient (Chinese) and less proficient (English) language. PCA results revealed that language proficiency increased the dimensions of lexical representations in the left inferior frontal gyrus, temporal pole, inferior temporal gyrus, supramarginal gyrus, angular gyrus, and fusiform gyrus. RSA results further showed that these regions represented semantic information and that higher semantic representations were observed in highly proficient language relative to less proficient language. These results suggest that language proficiency is associated with the neural representational dimensionality of semantic concepts.

以往的研究表明，语义概念具有高维神经表征的特点，而语言能力会影响语义处理。然而，语言能力是否会在神经水平上调节语义概念的维度表征，目前尚不清楚。为了解决这个问题，本研究采用主成分分析法（PCA）和表征相似性分析法（RSA）来研究高语言能力（汉语）和低语言能力（英语）的词汇在表征维度（RDs）和语义表征上的差异。PCA结果显示，语言能力提高了左侧额叶下回、颞极、颞下回、边际上回、角回和纺锤回的词汇表征维度。RSA 结果进一步表明，这些区域代表了语义信息，而且相对于语言水平较低的人，语言水平高的人语义表征更高。这些结果表明，语言能力与语义概念的神经表征维度有关。

The Basal Temporal Language Area (BTLA) is recognized in epilepsy surgery setting when cortical electrical stimulation (CES) of the ventral temporal cortex (VTC) trigger anomia or paraphasia during naming tasks. Despite acknowledging a ventral language stream, current cognitive language models fail to properly integrate this entity. In this SEEG study we used cortico-cortical evoked potentials in nine epileptic patients to assess and compare the effective connectivity of 73 sites in the left VTC of which 26 were deemed eloquent for naming after CES (BTLA). Eloquent sites connectivity supports the existence of a basal temporal language network (BTLN) structured around posterior projectors while the fusiform gyrus behaved as an integrator. BTLN was strongly connected to the amygdala and hippocampus unlike the non-eloquent sites, except for the anterior fusiform gyrus (FG). These observations support the FG as a multimodal functional hub and add to our understanding of ventral temporal language processing.

当对腹侧颞叶皮层（VTC）的皮层电刺激（CES）在命名任务中引发失认症或副失认症时，癫痫手术就会识别出颞叶基底语言区（BTLA）。尽管腹侧语言流得到了承认，但目前的认知语言模型未能正确整合这一实体。在这项 SEEG 研究中，我们使用九名癫痫患者的皮质皮层诱发电位来评估和比较左侧 VTC 73 个位点的有效连接性，其中 26 个位点在 CES（BTLA）后被认为对命名有影响。有效连接点支持围绕后投射器结构的基底颞叶语言网络（BTLN）的存在，而纺锤形回则充当整合器。基底颞叶语言网络与杏仁核和海马的连接性很强，这与非活跃点不同，但纺锤形前回（FG）除外。这些观察结果支持FG是一个多模式功能枢纽，并加深了我们对腹侧颞叶语言加工的理解。

Subject-object processing within relative clause (RC) attachments exhibits cross-linguistic asymmetries influenced by various factors, including filler-gap linear or structural distance, morphological case marking, and subject-first preferences (Lau & Tanaka, 2021). In the Basque language, filler-gap linear distance and morphological case marking have been posited as explanatory factors for the observed object relative clause (ORC) preference in prenominal RCs (Carreiras et al., 2010). However, recent studies by Yetano et al., (2019) have identified a behavioral preference for subject relative clause (SRC) constructions in Basque postnominal RCs. To ascertain the primary determinant impacting RC processing, we employed EEG signatures to scrutinize subject-object preferences in temporally ambiguous Basque postnominal RCs. Analysis of event-related potentials (ERPs) unveiled a SRC preference: ORCs elicited augmented negative (LAN: 200–400 ms) and positive (P600: 700–900 ms) components compared to SRCs. Our findings suggest that preferences in RC disambiguation are predominantly shaped by filler-gap linear distance and/or subject-first bias.

相对从句（RC）附着中的主客体加工表现出受各种因素影响的跨语言非对称性，这些因素包括填词间隙线性或结构距离、形态大小写标记和主语先行偏好（Lau & Tanaka, 2021）。在巴斯克语中，填词间隙线性距离和形态大小写标记被认为是在前名相对从句中观察到的宾语相对从句（ORC）偏好的解释因素（Carreiras et al.）然而，Yetano 等人（2019 年）的最新研究发现，巴斯克语名后 RC 中的主语相对从句（SRC）结构具有行为偏好。为了确定影响 RC 处理的主要决定因素，我们采用了脑电图特征来仔细研究时间上模棱两可的巴斯克名后 RC 中的主宾偏好。事件相关电位（ERPs）分析揭示了 SRC 偏好：与 SRC 相比，ORC 引起了增强的负向（LAN：200-400 ms）和正向（P600：700-900 ms）成分。我们的研究结果表明，RC消歧中的偏好主要是由填充间隙线性距离和/或主体优先偏差形成的。

Few studies have examined neural correlates of late talking in toddlers, which could aid in understanding etiology and improving diagnosis of developmental language disorder (DLD). Greater frontal gamma activity has been linked to better language skills, but findings vary by risk for developmental disorders, and this has not been investigated in late talkers. This study examined whether frontal gamma power (30–50 Hz), from baseline-state electroencephalography (EEG), was related to DLD risk (categorical late talking status) and a continuous measure of expressive language in n = 124 toddlers. Frontal gamma power was significantly associated with late talker status when controlling for demographic factors and concurrent receptive language (β = 1.96, McFadden’s Pseudo R² = 0.21). Demographic factors and receptive language did not significantly moderate the association between frontal gamma power and late talker status. A continuous measure of expressive language ability was not significantly associated with gamma (r = -0.07). Findings suggest that frontal gamma power may be useful in discriminating between groups of children that differ in DLD risk, but not for expressive language along a continuous spectrum of ability.

很少有研究对幼儿晚说话的神经相关性进行研究，而这有助于了解发育性语言障碍（DLD）的病因并改进诊断。额叶伽马活动的增加与语言能力的提高有关，但研究结果因发育障碍的风险而异，而且尚未对晚期说话者进行研究。本研究考察了基线状态脑电图（EEG）显示的额叶伽玛功率（30-50赫兹）是否与DLD风险（分类的晚说话状态）有关，并对124名幼儿的语言表达能力进行了连续测量。在控制人口统计学因素和同时接受语言的情况下，额叶伽玛功率与晚说话状态有显著相关性（β = 1.96，麦克法登伪R2 = 0.21）。人口统计学因素和接受性语言并不能显著调节额叶伽玛功率与晚说话者身份之间的关系。语言表达能力的连续测量与伽马值（r = -0.07）无明显关联。研究结果表明，额叶伽玛功率可能有助于区分患有迟缓性失语症风险不同的儿童群体，但对于表达语言能力的连续测量则没有作用。

The neural mechanisms supporting semantic association and categorization are examined in this study. Semantic association involves linking concepts through shared themes, events, or scenes, while semantic categorization organizes meanings hierarchically based on defining features. Twenty-three adults participated in an fMRI study performing categorization and association judgment tasks. Results showed stronger activation in the inferior frontal gyrus during association and marginally weaker activation in the posterior middle temporal gyrus (pMTG) during categorization. Granger causality analysis revealed bottom-up connectivity from the visual cortex to the hippocampus during semantic association, whereas semantic categorization exhibited strong reciprocal connections between the pMTG and frontal semantic control regions, together with information flow from the visual association area and hippocampus to the pars triangularis. We propose that demands on semantic retrieval, precision of semantic representation, perceptual experiences and world knowledge result in observable differences between these two semantic relations.

本研究探讨了支持语义联想和分类的神经机制。语义联想是指通过共同的主题、事件或场景将概念联系起来，而语义分类则是根据定义特征对意义进行分级组织。23 名成年人参加了一项 fMRI 研究，执行分类和联想判断任务。结果显示，在联想过程中，额叶下回的激活较强，而在分类过程中，颞叶后中回（pMTG）的激活稍弱。格兰杰因果关系分析表明，在语义联想过程中，视觉皮层与海马之间存在自下而上的联系，而语义分类过程中，pMTG与额叶语义控制区之间存在很强的互惠联系，同时，信息流也从视觉联想区和海马流向三角旁。我们认为，对语义检索的要求、语义表征的精确性、知觉经验和世界知识导致了这两种语义关系之间可观察到的差异。

Infants quickly recognize the sounds of their mother language, perceiving the spectrotemporal acoustic features of speech. However, the underlying neural machinery remains unclear. We used an auditory evoked potential termed frequency-following response (FFR) to unravel the neural encoding maturation for two speech sound characteristics: voice pitch and temporal fine structure. 37 healthy-term neonates were tested at birth and retested at the ages of six and twelve months. Results revealed a reduction in neural phase-locking onset to the stimulus envelope from birth to six months, stabilizing by twelve months. While neural encoding of voice pitch remained consistent across ages, temporal fine structure encoding matured rapidly from birth to six months, without further improvement from six to twelve months. Results highlight the critical importance of the first six months of life in the maturation of neural encoding mechanisms that are crucial for phoneme discrimination during early language acquisition.

婴儿能迅速识别母语的声音，感知语音的谱时声学特征。然而，其背后的神经机制仍不清楚。我们使用一种被称为频率跟随反应（FFR）的听觉诱发电位来揭示两种语音声音特征的神经编码成熟过程：语音音高和时间精细结构。37 名健康足月新生儿在出生时接受了测试，并在 6 个月和 12 个月大时接受了复测。结果显示，从出生到 6 个月期间，神经与刺激包络的锁相起始时间减少，到 12 个月时趋于稳定。虽然声调的神经编码在各年龄段保持一致，但时间精细结构编码从出生到六个月迅速成熟，从六个月到十二个月没有进一步改善。研究结果凸显了出生后头六个月对神经编码机制成熟的至关重要性，而神经编码机制对早期语言习得过程中的音素辨别至关重要。

Language is processed incrementally, with addressees considering multiple candidate interpretations as speech unfolds, supporting the retention of these candidate interpretations in memory. For example, after interpreting the utterance, “Click on the striped bag”, listeners exhibit better memory for non-mentioned items in the context that were temporarily consistent with what was said (e.g., dotted bag), vs. not consistent (e.g., dotted tie), reflecting the encoding of linguistic context in memory. Here, we examine the impact of moderate-severe traumatic brain injury (TBI) on memory for the contexts of language use. Participants with moderate-severe TBI (N=71) and non-injured comparison participants (NC, N=85) interpreted temporarily ambiguous utterances in rich contexts. A subsequent memory test demonstrated that participants with TBI exhibited impaired memory for context items and an attenuated memory advantage for mentioned items compared to NC participants. Nonetheless, participants with TBI showed similar, although attenuated, patterns in memory for temporarily-activated items as NC participants.

语言是渐进式处理的，随着语音的展开，听众会考虑多种候选解释，从而支持在记忆中保留这些候选解释。例如，在解释 "点击条纹包 "这句话后，听者会对上下文中暂时与所说内容一致的未提及项目（如点状包）与不一致的项目（如点状领带）表现出更好的记忆，这反映了记忆中的语言上下文编码。在此，我们研究了中度严重创伤性脑损伤（TBI）对语言使用语境记忆的影响。患有中度严重创伤性脑损伤的参与者（71 人）和未受伤的对比参与者（NC，85 人）在丰富的语境中解释了暂时含糊不清的语句。随后的记忆测试表明，与 NC 参与者相比，患有创伤性脑损伤的参与者对语境项目的记忆受损，对提及项目的记忆优势减弱。尽管如此，患有创伤性脑损伤的受试者对临时激活项目的记忆模式与NC受试者相似，尽管有所减弱。

Revisiting nonword repetition as a clinical marker of developmental language disorder: Evidence from monolingual and bilingual L2 Cantonese 重新审视作为发育性语言障碍临床标志的非词重复：来自单语和双语中级粤语的证据

Cross-linguistically, nonword repetition (NWR) tasks have been found to differentiate between typically developing (TD) children and those with Developmental Language Disorder (DLD), even when second-language TD (L2-TD) children are considered. This study examined such group differences in Cantonese. Fifty-seven age-matched children (19 monolingual DLD (MonDLD); 19 monolingual TD (MonTD); and 19 L2-TD) repeated language-specific nonwords with varying lexicality levels and Cantonese-adapted quasi-universal nonwords. At whole-nonword level scoring, on the language-specific, High-Lexicality nonwords, MonDLD scored significantly below MonTD and L2-TD groups which did not differ significantly from each other. At syllable-level scoring, the same pattern of group differentiation was found on quasi-universal nonwords. These findings provide evidence from a typologically distinct and understudied language that NWR tasks can capture significant TD/DLD group differences, even for L2-Cantonese TD children with reduced language experience. Future studies should compare the performance of an L2-DLD group and evaluate the sensitivity and specificity of Cantonese NWR.

跨语言研究发现，非单词重复（NWR）任务可区分典型发育（TD）儿童和发育性语言障碍（DLD）儿童，即使考虑到第二语言TD（L2-TD）儿童也不例外。本研究用粤语考察了这种群体差异。57名年龄匹配的儿童（19名单语DLD（MonDLD）；19名单语TD（MonTD）；19名第二语言TD）重复了不同词性水平的特定语言非词和适应广东话的准通用非词。在整个非词水平的评分中，在特定语言的高词性非词上，MonDLD 组的得分明显低于 MonTD 组和 L2-TD 组，这两个组之间没有明显差异。在音节级评分中，准通用非词上也发现了同样的组别分化模式。这些研究结果从一种类型独特、研究不足的语言中提供了证据，证明即使对于语言经验较少的 L2-Cantonese TD 儿童，NWR 任务也能捕捉到显著的 TD/DLD 组别差异。未来的研究应比较 L2-DLD 组的表现，并评估粤语 NWR 的敏感性和特异性。

Brain asymmetries are hypothesized to reduce functional duplication and thus have evolutionary advantages. The goal of this study was to examine whether early brain lateralization contributes to skill development within the speech-language domain. To achieve this goal, 25 infants (2–13 months old) underwent behavioral language examination and fMRI during sleep while listening to forward and backward speech, and then were assessed on various language skills at 55–69 months old. We observed that infant functional lateralization of the superior temporal gyrus (STG) for forward > backward speech was associated with phonological, vocabulary, and expressive language skills 4 to 5 years later. However, we failed to observe that infant language skills or the anatomical lateralization of STG were related to subsequent language skills. Overall, our findings suggest that infant functional lateralization of STG for speech perception may scaffold subsequent language acquisition, supporting the hypothesis that functional hemisphere asymmetries are advantageous.

据推测，大脑不对称可减少功能重复，从而具有进化优势。本研究的目的是探讨早期大脑侧向化是否有助于言语-语言领域的技能发展。为了实现这一目标，25 名婴儿（2-13 个月大）在睡眠中聆听正向和反向语音时接受了行为语言检查和 fMRI 检查，并在 55-69 个月大时接受了各种语言技能评估。我们观察到，婴儿颞上回（STG）对前向和后向言语的功能侧化与 4 至 5 年后的语音、词汇和语言表达能力有关。然而，我们未能观察到婴儿的语言技能或 STG 的解剖侧化与随后的语言技能有关。总之，我们的研究结果表明，婴儿期 STG 在言语感知方面的功能侧化可能会为其后的语言习得提供支架，从而支持功能半球不对称具有优势的假设。
