This study tested this hypothesis by assessing the automatic imitation effect, that relies on internal representation of movement, in children with and without DCD, using a comparison of the behavioural effect and the neural processes contributing to it. Reaction times and EEG event-related potentials were measured during an automatic imitation finger-tapping task in 36 children with DCD (age: M = 12.9 years; SD = 2.0) and 36 matched typically developing children (age: M = 12.9 years; SD = 1.9). Contrary to our expectations, children with DCD demonstrated significantly stronger automatic imitation effects than children without DCD. This was accompanied by altered neural processing, evidenced by a significant delay in the visual processing of body parts, as reflected in N190 latency. However, no differences were observed in motor preparation, as indexed by the readiness potential. These findings suggest that children with DCD do not exhibit reduced automatic imitation, and do not support the assumption of impaired internal representation of action in this group. Yet, deficits in control processes, such as alterations in the timing of perception, may contribute to the difficulties in DCD.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"192 ","pages":"Pages 18-34"},"PeriodicalIF":3.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145079769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite its central role for neurocognitive attention research, there have been no direct replications and only few conceptual replications of this seminal work. Within the context of #EEGManyLabs, an international community-driven effort to replicate the most influential EEG studies ever published, the present study was selected due to its strong impact on the study of selective attention. We revisit the idea of the N2pc being an indicator of attentional selectivity by delivering a high powered direct replication of Eimer's work through analysis of 779 datasets acquired from 22 labs across 14 countries. Our results robustly replicate the N2pc to form stimuli, but a direct replication of the N2pc to color stimuli technically failed. We believe that this pattern not only sheds further light on the functional significance of the N2pc as an electrophysiological marker of attentional selectivity, but also highlights a methodological problem with selecting analysis windows a priori. By contrast, the consistency of observed ERP patterns across labs and analysis pipelines is stunning, and this consistency is preserved even in datasets that were rejected for (ocular) artifacts, attesting to the robustness of the ERP technique and the feasibility of large-scale multilab EEG (replication) studies.</p>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"190 ","pages":"304-341"},"PeriodicalIF":3.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144798437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the brain signal variability underlying self-processing remains scarcely treated in the literature. Additionally, less is known about whether the processing of self-referential visual content can be modulated by facial expressions of emotion, as these resemble more natural situations than neutral expressions. This study therefore investigated the brain signal variability underlying self-referential visual processing and its possible interaction with emotional facial expressions, as indexed by multiscale entropy analysis (MSE). This metric captures the temporal complexity or variability contained in neural patterns at varying timescales. Thirty-two participants were presented with distinctive facial identities (self, friend, and unknown) displaying different facial expressions (happy, neutral, and angry) and performed an identity recognition task. Our results showed that brain signal variability decreases in response to self-faces compared to other identities. Similarly, brain signal variability also decreases for friend faces relative to unknown faces. This reduction in complexity could be indicative of greater efficiency during the preferential processing of personally relevant stimuli. Furthermore, the data observed here show that self-processing is unaffected by facial expressions of emotion, suggesting an independent processing of identity from more dynamic facial information, particularly when the task demands are focused on identity recognition. These results provide novel evidence of the moment-to-moment brain signal variability involved in the identity of the self and others. The evidence presented here adds to a growing literature highlighting the relevance of neural variability for understanding brain-behavior relationships.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"192 ","pages":"Pages 1-17"},"PeriodicalIF":3.3,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To gain a better understanding of the neural correlates of oculomotor control, we measured horizontal smooth pursuit tracking behavior in 14 patients following childhood hemispherectomy. Relative to developmentally typical age-matched controls, patients exhibited a bilateral and asymmetric pursuit deficit with reduced ipsilesional but elevated contralesional eye speeds, and asymmetric accompanying ‘catch up’ saccades. The atypical pursuit behavior could not be explained by a sensory deficit associated with their hemianopia, as patients adjusted their eye position to maintain visibility of the target. The pursuit deficit was also not accounted for by a general motor impairment as patients made faster catch-up saccades than controls, particularly in the ipsilesional direction. These results, all of which hold irrespective of whether the right or left hemisphere is resected, demonstrate that patients can compensate for reduced pursuit speeds by modulating their saccade characteristics. Overall, this study represents the most comprehensive characterization of smooth pursuit disturbances in hemispherectomy patients. Our results elucidate: 1) the competence of a single hemisphere for generating pursuit and compensatory behaviors; 2) the lack of a hemispheric bias supporting pursuit given large-scale cortical disruptions; and 3) that intact horizontal pursuit likely requires the interaction of brain circuitry across both hemispheres.</div></div>","PeriodicalId":10758,"journal":{"name":"Cortex","volume":"191 ","pages":"Pages 266-282"},"PeriodicalIF":3.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144988197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous experiments using hierarchical letters (large letters made of small ones) have reported a global precedence in young adults. Here, we aimed to define neurophysiological markers of a possible global/local bias during the implicit processing of new faces. We performed two ERP experiments on young adults using hierarchical/compound facial stimuli, either congruent (eyes replaced by small faces) or incongruent (objects as eyes), with peripheral small objects and faces, respectively, grafted as distracters. In Experiment 1, the face-sensitive N170/VPP was largest for regular faces and progressively decreased through congruent and incongruent hierarchical faces, evidencing disruption of the global bias. In Experiment 2, N170/VPP was similar between both hierarchical faces and a new objects condition, likely due to the visual angle increase used to prevent a global bias. Moreover, an N200-350 with maximal amplitude for incongruent faces and objects appeared in both experiments, suggesting a perceptive mismatch with a canonical face template. Experiment 2 also revealed a posterior negativity ∼220–330 msec for objects and faces, likely indicating access to known categories, as well as an object-specific late positivity that could reflect pre-semantic, visual recognition of common objects. Source reconstruction highlighted the significant involvement of ventral (predominantly right-sided) visual regions in these ERP modulations.

Research has predominantly focused on episodic memory, where ε4 carriers are usually impaired, while semantic memory functioning has received less attention. To evaluate current evidence on the influence of <em>APOE</em> ε4 on semantic memory, we systematically reviewed the research literature assessing semantic memory in non-clinical adult populations according to the PRISMA guidelines. We reviewed 17 studies that revealed high heterogeneity in how semantic memory is conceptualised and assessed. When tested via standard neuropsychological tests (i.e., category fluency, naming, language comprehension, and general knowledge), ε4 carriers did not significantly differ from non-carriers. Instead, ε4 carriers showed lower performance than non-carriers when assessed via more complex semantic memory tasks (i.e., longer category fluency tasks, autobiographical memory tasks, measures of semantic clustering). The impact of <em>APOE</em> ε4 on semantic memory thus appears to be restricted to these more complex tasks, which could constitute a better match to episodic memory tasks for which <em>APOE</em> effects are typically observed, though a mediating role of executive functions should also be considered.

As factors such as multi-sensory acuity loss and relatively increased reliance on prior knowledge may increase as we age, and these are considered risk factors for hallucination proneness, we hypothesised that reported decreases in hallucinations might reflect underreporting due to stigma. We therefore sought to measure hallucination proneness in 44 healthy adults spanning the adult lifespan (younger age group; n = 22; age 19–39 years, mean 27.2 ± 5.5; older age group n = 22; age 59–79 years, mean 68.0 ± 5.8), quantifying the tendency to experience complex and simple hallucinations in an experimental environment designed to elicit hallucinations. We find that reports of complex hallucinations (those representing objects, scenes, etc) are lower in older adults than in younger adults, both in real time and retrospectively. None of our measured cognitive or sensory measures (visual acuity, contrast sensitivity, perceptual reorganisation, imagery vividness, memory inhibition, and suggestibility) mediate this relationship.
