The response is often used in research investigating the cognitive mechanisms that underlie speech processing, but more recently has been employed in clinical research seeking to identify the specific deficits that contribute to a host of speech and language impairments. The PMN has long been assumed to be sensitive only to phonological manipulations. Here, we test that assumption in a classic phoneme blending task, comparing responses to phonological mismatches and speaker voice mismatches. Participants were instructed to blend nonword primes segmented into onset and rhyme (e.g.,/l/+/ɛk/), which were followed by targets that matched or mismatched based on either phonological expectancy (e.g., match:/lɛk/; mismatch:/wɛk/) or speaker voice expectancy (match: same voice; mismatch: different voice). Analysis of the 150–400 ms post-target window revealed a predicted negative ERP response to phoneme mismatch vs match trials (i.e., the PMN, as typically characterised). Crucially however, analysis of speaker trials revealed a similar pattern of results in response to speaker mismatch vs speaker match. Our findings are discussed in light of ongoing debates about the functional sensitivity and characterization of the PMN, alongside strong recommendations against the use of the component as a biomarker for phonological deficits until further research clarifies the validity of a phonology-specific ERP response.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"224 ","pages":"Article 109380"},"PeriodicalIF":2.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146137792","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}

This study investigated whether repeated training in categorizing filtered scenes improves peripheral scene recognition by enhancing spatial frequency processing. Ten MD patients and ten age- and gender-matched controls performed a scene categorization task (indoor vs. outdoor) using LSF or HSF images. Both groups completed a 12-session training protocol: patients performed the task at their preferred retinal location (PRL), and controls fixated with their fovea and viewed stimuli through an individualized artificial scotoma matched to their paired patient. Before training, MD patients showed a marked deficit for HSF scenes compared to controls, and a milder deficit for LSF scenes. After training, patients exhibited a significant improvement in categorizing LSF scenes, and an improvement specifically limited to HSF outdoor scenes, suggesting enhanced use of preserved peripheral information and partial compensation for the HSF deficit. Older controls also showed reduced performance for HSF scenes in peripheral vision, and similarly benefited from training. These results highlight the potential of perceptual training to enhance peripheral visual processing in MD patients, particularly by leveraging coarse visual cues.

This study employed a pre/post short-term longitudinal design, where participants completed 10 days of Dutch language learning. Using Event-Related Potentials (ERPs) and Time-Frequency Representations (TFRs), we examined neurophysiological signatures of novel word learning and the role of IC, WM, and bilingual experience.

Greater Bilingual experience predicted greater N400 reductions for noncognates, suggesting more efficient integration for words with shared representations. In contrast, stronger IC was linked to smaller N400 reductions for noncognates, indicating greater cognitive effort in managing novel lexical competition. TFR analyses showed increased theta power for cognates, suggesting enhanced memory encoding, while noncognates elicited greater alpha suppression, suggesting heightened IC demands. However, individual differences did not significantly modulate these effects, as neither bilingual experience nor IC predicted alpha or theta power at post-test, suggesting that the oscillatory dynamics supporting lexical learning were driven by task demands rather than individual variability. Together, these findings indicate that bilingual experience may facilitate lexical integration, whereas IC may play a critical role in managing interference during word retrieval.

The current study examined behavioral and neural predictors of externalizing behaviors in a transdiagnostic sample of school-age children (N = 90; ages 7–13 years; 48 autistic, 42 non-autistic). Parents completed measures of EF (Behavior Rating Inventory of Executive Function, Second Edition; BRIEF-2) and externalizing behaviors (Behavior Assessment System for Children, Third Edition; BASC-3).

After controlling for age and FSIQ, the BRIEF-2 composite index scores (Behavioral, Emotional, and Cognitive Regulation) significantly predicted externalizing behaviors. Seed-to-seed analyses revealed positive associations between externalizing behaviors and connectivity among the left superior parietal lobule, left inferior parietal lobule, anterior insula, and lateral frontal ECN nodes. Seed-to-voxel analyses showed widespread alterations, including increased connectivity within frontoparietal executive regions alongside reduced connectivity in salience-related areas, such as cingulate and insula. This dual connectivity profile suggests a neural mechanism involving compensatory executive engagement paired with diminished salience processing that may contribute to behavioral dysregulation.

SoJA is ubiquitous in human-human interaction. Therefore, it is both interesting as well as relevant to understand the factors that affect the formation of SoJA both in human-human and in human-robot interaction. On the one hand, previous work suggests that sensorimotor cues may be the main determinant of “lower-level” implicit SoJA in human-human joint action. On the other hand, recent work shows that contextual factors, such as perceived intentionality, can impact the formation of implicit SoJA with a humanoid robot. In the current study, we aimed to investigate, using behavioral and electroencephalography (EEG) measures, whether endowing a humanoid robot with a precisely human sensorimotor pattern would be sufficient to elicit SoJA with the robot, even without manipulating the perceived intentionality of the robot. Participants completed a joint task with another human, and with a robot that was controlled by another human, thus endowing the robot with a precisely human sensorimotor repertoire. Importantly, participants completed two sessions with this controlled robot. In one session, they were (factually) told that the robot was controlled by another human. In another session, they were told that the robot was pre-programmed. We expected that participants may attribute less intentionality to the robot they believed was pre-programmed. In either session, participants' perception regarding the robot's intentionality was not explicitly manipulated. Interval estimates for self- and other-generated actions were used to estimate SoJA. In addition, we also measured participants' readiness potential (RP) for self- and partner actions, and their N100 responses for self- and partner-generated sensory outcomes in the task. The results show that temporal estimates, and ERPs, did not differ between self- and partner-generated action-outcome conditions, in both human-human and human-robot sessions. Thus, these results suggest that endowing a humanoid robot with a human sensorimotor pattern may be sufficient to elicit SoJA in joint action with the robot, regardless of the intentionality attributed to the robot. Furthermore, an exploratory spectral analysis of movement-related beta activity suggested that people may nevertheless disengage earlier from the joint action when interacting with a robot partner, as compared to a human partner. Together, our results contribute to understanding the mechanisms that underlie the emergence of SoJA in joint action, as well as the extent to which artificial agents, such as humanoid robots, can be integrated into our teamwork as “full” interaction partners.</div></div>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":"223 ","pages":"Article 109372"},"PeriodicalIF":2.0,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146015896","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}
