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.</div></div>","PeriodicalId":50118,"journal":{"name":"Journal of Neurolinguistics","volume":"75 ","pages":"Article 101251"},"PeriodicalIF":1.2,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628730","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}

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.</div></div>","PeriodicalId":50118,"journal":{"name":"Journal of Neurolinguistics","volume":"74 ","pages":"Article 101249"},"PeriodicalIF":1.2,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529775","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}

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.

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.

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.

We tested Polish-English migrants living in the UK (L2 environment) for an average of ten years and Polish-English controls living in Poland (L1 environment).

Our focus was on two event-related components previously associated with the ease of lexical access: P2 and N300. We found no modulations related to N300, but some in the P2 time window, although their distribution was more frontal than previously reported. There was no main effect of the long-term immersion in the L2 environment, suggesting that the effectiveness of producing words in L1 was similar across the two groups. However, the short-term change in the language environment modulated the early positivity in migrants: smaller frontal positivity was reported in response to picture naming after the short reimmersion in the L1 environment than during the L2 immersion.
