In neurolinguistics and the neurobiology of language, processing models that parallelize meaning and grammar have acquired theoretical and empirical support over more modular theories. Yet, parallel models too should account for serial, sequential, or blocking effects of one type of representation on others. In this study, we used ERPs to assess whether and how the mental lexicon restricts the applicability of morphosyntactic operations, and how those, in turn, constrain on-line meaning composition. The stimuli were Norwegian sentences with the form ‘N V Adj’. The adjective was either correctly or incorrectly inflected for gender or number relative to the noun, and the noun was either a real word or a pseudoword built around a pseudoroot. ERPs show that agreement only applies between an adjective and a noun that contains a real lexical root, and that lexical meanings are only composed for correctly inflected words. We could not find agreement effects for pseudonouns or differences between gender and number features. Our results suggest that some grammatical processes may draw from and depend on lexical storage, in particular of lexical roots, and that compositional semantic processes may depend on the well-formedness of the outputs of such grammatical processes.
在神经语言学和语言神经生物学中，将意义和语法并行化的处理模型已经获得了理论和经验上的支持，而更多的是模块化理论。然而，并行模型也应考虑一种表征类型对其他表征类型的串行、顺序或阻塞效应。在本研究中，我们使用ERPs评估了心理词典是否以及如何限制形态句法操作的适用性，以及这些操作如何反过来限制在线意义构成。刺激物是 "N V Adj "形式的挪威语句子。相对于名词而言，形容词的性别或数目选择正确或错误，而名词要么是一个实词，要么是一个围绕着假词根的假词。ERPs表明，一致只适用于包含真实词根的形容词和名词，词义只由正确的词根构成。我们无法发现假名的一致效应，也无法发现性别和数字特征之间的差异。我们的研究结果表明，某些语法过程可能借鉴并依赖于词性存储，尤其是词根的存储，而语义构成过程可能依赖于此类语法过程输出结果的格式正确性。

The majority of people with Parkinson's disease (PD) experience changes in speech production, most notably reduced vocal volume and imprecise articulation, that limit speech intelligibility and may contribute to significant declines in quality of life. We previously conducted a randomized control trial comparing two intensive treatments, voice (LSVT LOUD) or articulation (LSVT ARTIC) to assess single word intelligibility in the presence of background noise (babble and mall). Participants (64 PD and 20 Healthy) read words from the diagnostic rhyme test (DRT), an ANSI Standard for measuring intelligibility of speech, before and after one month (treatment or no treatment). Teams of trained listeners blindly rated the data. Previously we found that single word intelligibility in the presence of both noise conditions improved in PD participants who had LSVT LOUD compared to the groups that had LSVT ARTIC or no treatment. The current study analyzed the distinctive features (Compactness, Graveness, Sustention, Sibilation, Nasality, Voicing), of the initial consonants of words in the DRT test to determine what in particular is contributing to the differences in word intelligibility that we previously identified. The distinctive features of the DRT assess the valving nature of consonant production. Intensive treatment targeting vocal loudness (LSVT LOUD) had a greater positive effect on consonant intelligibility than treatment targeting articulation (LSVT ARTIC) for all distinctive features in background Babble noise and for 5/6 distinctive features in background Mall noise. Due to the definition of the distinctive features, we can conclude that the intelligibility gains seen following LSVT LOUD treatment are due to improved vocal tract valving.

Our ability to recognize tens of thousands of words is attributed to a rich lexicon in our brains, referred to as the orthographic lexicon. Understanding how this lexicon is organized in the brain is key to uncovering the neural mechanisms of visual word recognition. Event-related potentials (ERPs) are an effective tool for investigating these mechanisms. A widely observed phenomenon in orthographic processing is a 250-ms ERP difference between real words and pseudowords (or between high-frequency (HF) and low-frequency (LF) words). However, this 250-ms ERP difference has been explained by competing theories—one attributing it to the activation of the orthographic lexicon, and the other suggesting it represents a prediction error signal related to orthographic processing. To resolve this controversy, the present study uses handwritten words as control stimuli alongside printed words, as the 250-ms ERP difference is not observed with handwritten words. ERPs were obtained during an implicit reading task (color decision) for printed HF words, printed LF words, handwritten HF words, and handwritten LF words. The results show that the 250-ms ERP difference is significant when comparing printed LF words to printed HF words, handwritten LF words, and handwritten HF words. This finding indicates that the 250-ms ERP difference reflects increased neural activation to printed LF words compared to printed HF words, likely representing a prediction error signal in orthographic processing. These results support the Interactive Account of orthographic processing, clarify previous ERP findings in the literature, and underscore the potential applications of the 250-ms ERP difference (labeled as ND250) in future research.

Auditory verbal working memory (AVWM) is a crucial cognitive process that allows individuals to store and manipulate auditory information. This study investigates the effects of transcranial direct current stimulation (tDCS) on AVWM performance using nonsense auditory syllables and examines the role of different stimulation montages. Thirty healthy participants received tDCS with three stimulation montages: anode-left auditory cortex/cathode-left dorsolateral prefrontal cortex (DLPFC), anode-left auditory cortex/cathode-right cheek, and sham stimulation. Results showed that anodal tDCS over the left auditory cortex with concurrent cathodal stimulation over the left DLPFC improved 1-back task performance, while anodal tDCS over the left auditory cortex with cathodal stimulation over the right cheek improved both 1-back and 2-back task performance. These findings suggest that the left auditory cortex plays a critical role in AVWM and highlight the importance of considering stimulation montage in tDCS studies.

Social interactions are shaped by the way individuals communicate. Listeners form impressions based on how someone sounds, and the message conveyed can be interpreted differently depending on who the speaker is. We investigated on-line sentence processing focusing on the role of the speaker's gay- vs. heterosexual-sounding voice in the construction of meaning. Event-related brain potentials were recorded while participants listened to two gay- and two heterosexual-sounding male speakers uttering stereotypical sentences. We manipulated whether the sentences referred to professions stereotypically congruent or incongruent with the speakers' perceived sexual orientation. Results showed that the interplay between the speaker's voice and message content influenced sentence processing early after an incongruent stereotype was presented. The interaction was maximal at frontal sites, with a larger negativity for stereotypically-congruent than for stereotypically-incongruent professions when uttered by gay-sounding speakers. These results suggest that the perception of the speaker as gay- or straight-sounding is quickly used by listeners to build the message meaning. The inconsistency between vocal and linguistic information modulates a frontal negativity, potentially indicating control processes during sentence comprehension put in place to deal with the inconsistency.

This paper discusses the relationship between monitoring, control, conscious awareness, and attention in language production. Instead of focusing on a specific theory, I will examine these relationships within a framework that accommodates multiple (complementary) monitoring views, and discuss key differences between situations where competition is resolved internally vs. those that recruit external control. The takeaway message is that production performance is optimized by self-regulating monitoring-control loops, which operate largely subconsciously, but conscious awareness can be —and often is— triggered by the monitor. When triggered, in conjunction with the control system, such awareness can lead to attentional control of both the primary production process, as well as the monitoring process. I will also touch upon the repair process and its relation to these issues, and end by discussing some of the open questions as possible avenues for future research.

In this review, challenges related to the measurement of word durations in language production are identified, highlighting gaps in current theoretical frameworks and the resulting difficulty in interpreting available evidence. To compensate for limited theoretical predictions regarding response durations in spoken language, we turn to other fields, such as written production and motor control, to provide informative analogies. In written production, reliable effects on durations have been observed but the field similarly suffers from the absence of clear predictions from the available models, limiting interpretations. Since word durations are the result of motor programming and execution, evidence from motor control is particularly relevant. Recent theoretical proposals suggest that planning and execution stages overlap in time, with response planning continuing even after the initiation of the motor response, making variations in durations arise from either planning or execution processes. In addition, they propose a gating mechanism to launch response initiation. Similar dynamics could be easily assumed in language production, which could help bridge the gap from response selection to response execution and extend current models of language production to account for motor execution and predict word durations. We end by outlining pending questions for the field of language production, and some recommendations to tackle them in the future.

Prior research has established a positive link between bilingualism and creativity. However, despite clear evidence for the positive role of L2 proficiency in creativity, few neuroimaging studies have provided insights into its underlying neural mechanisms. To bridge this gap, we employed a chain free association task and functional near-infrared spectroscopy (fNIRS) to capture cortical activity in the temporo-parietal junction (TPJ) and the frontopolar cortex (FPC) during the task. Our behavioral results confirmed a positive association between L2 proficiency and creative performance. Neuroimaging data revealed that TPJ activity in bilinguals positively correlated with their creativity, while FPC activity was negatively correlated with their creativity. Furthermore, mediation analysis indicated that both TPJ and FPC activity mediated the relationship between L2 proficiency and creative performance. These preliminary findings suggest the potential involvement of both the default mode network (DMN) and the executive function network (EFN) in bilinguals’ creative cognition.

Although language disorders associated with the left supplementary motor area are well-known, a clear mechanism of this pathology is still not fully understood. In this study, we report the case of a right-handed patient who underwent resection of oligodendroglioma located in the right superior frontal gyrus. In the immediate postoperative period, he exhibited transient severe left hemiparesis together with complete aphasia, which both gradually improved after the 3rd postoperative day. Postoperative magnetic resonance imaging ruled out any vascular or other complications in the contralateral site related to speech disorders. After 3 months, the patient had almost fully recovered. To the best of their knowledge, the authors provide the first description of complete transient crossed aphasia associated with resection of the right supplementary motor area.

Acting on the world requires the right action at the right time. This is perhaps most easily seen in music where the meaning of a piece is encoded explicitly by both the pitches of musical notes and their duration. We used these features to operationalise the production of desired qualia of movements as note pitches as compared to movement timing as note durations. Participants listened to and imitated simple melodies as accurately as possible while lying in an ultra-high field 7T MRI scanner. Melodies consisted of either a series of different pitches of equal duration or a single pitch repeated at different durations. Both tasks engaged a broad motor network similar to speech and other complex dynamic movements. However, imitation for timing preferentially activated the ventral striatum of the basal ganglia while imitation for pitch preferentially activated lobule VI of the cerebellum and temporal lobe auditory association areas. These findings are consistent with the role of the basal ganglia in sound sequence learning and with the role of the cerebellum in refining movement based on sensory feedback. Imitating melodies provides a simple but effective framework for manipulating the qualities and timings of sound production by the speech-motor system, even when no words are spoken.

This is perhaps most easily seen in music where the meaning of a piece is encoded explicitly by both the pitches of musical notes and their duration. We used these features to operationalise the production of desired qualia of movements as note pitches as compared to movement timing as note durations. Participants listened to and imitated simple melodies as accurately as possible while lying in an ultra-high field 7T MRI scanner. Melodies consisted of either a series of different pitches of equal duration or a single pitch repeated at different durations. Both tasks engaged a broad motor network similar to speech and other complex dynamic movements.
