We investigated perceptual reorganization using the scale illusion, in which interleaved tone sequences presented separately to the two ears are typically heard as continuous melodic streams.Thirty participants listened to illusory, zigzag, and continuous sequences during EEG recording and reported whether each sequence sounded continuous or zigzag. Temporal response function models characterized neural encoding and reconstruction of amplitude-envelope (envelope) and pitch-change magnitude features. We tested whether neural responses during illusory listening corresponded more closely to reference patterns associated with the physical zigzag structure or reported continuous organization. Illusory sequences were predominantly categorized as Continuous and elicited longer RTs than non-illusory sequences. Encoding models revealed delayed pitch-change magnitude responses in the illusory condition, whereas envelope latencies remained comparatively stable. For pitch-change magnitude, reconstruction correlations computed over the full sequence exceeded chance levels estimated separately for each reference, with higher correlations for the continuous reference. Envelope correlations exceeded neither chance level, despite a small relative preference for the zigzag reference. These findings show that neural response timing and relative correspondence with the tested reference patterns depend on the modeled feature during the scale illusion. The reconstruction result concerns correlations across complete sequences and does not establish continuous tracking of the perceived melody.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-18"},"PeriodicalIF":3.0,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149118312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, analyses that include both the previous stimulus and previous response unmasked repulsive effects at the sensory level that were otherwise concealed. Moreover, attractive serial biases fail to scale with environmental correlations, challenging their primary role in maintaining stability. We propose the \"precision hierarchy hypothesis,\" grounded in predictive processing, as a unifying framework for these seemingly contradictory findings. Repulsive effects naturally emerge when priors-shaped by recent trials-are highly precise, making small deviations in incoming input more probable under alternative priors. We further propose that prior precision decreases across hierarchical levels. A higher precision at lower sensory levels leads to repulsive effects, as even small deviations in incoming signal are in conflict with the prior. In contrast, attractive biases emerge at higher, more abstract levels, where deviations are integrated with broader conceptual priors. By dynamically shaping prior precision according to environmental correlations, perception remains adaptive, balancing the need for stability with the sensitivity to detect meaningful changes in the environment. This framework reconciles diverse findings on serial effects and provides testable predictions for future research.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-20"},"PeriodicalIF":3.0,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149118244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the neural correlates of speech processing in such conditions have been well studied, this is not the case for sign language. Thus, it is unknown whether the neural mechanisms involved in this process are comparable across language modalities. One reason for the lack of studies in sign language might be attributed to the difficulties in adapting perceptual manipulations from the context of speech to sign language. In the present study, we aim to address the gap in the literature by investigating whether the neural correlates for processing language presented in perceptually challenging conditions are similar across the visual and auditory modalities, using manipulations of background noise and spectral degradation that are comparable between languages and a within-subject design. We recruited 22 hearing signers who did a perceptual attention task while in an MRI scanner, in which the signal is either clear, presented in background noise, or spectrally degraded. Overall, our results suggest that language processing in perceptually challenging conditions relies primarily on modality-specific mechanisms rather than a shared, modality-independent neural system. Whereas speech processing appeared relatively robust to perceptual degradation, sign language recruited additional visual indicating modality-dependent compensatory strategies. These findings refine current neurobiological models of language by demonstrating that perceptual challenge interacts fundamentally with language modality.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-22"},"PeriodicalIF":3.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149076462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, covert spatial attention spontaneously tracks object locations in working memory and is thought to enable feature binding at those location markers. However, whether object locations are attended concurrently as multiple objects are presented in a sequence remains a topic of debate. Here, we investigated whether spatial attention contributes to sustained active memory maintenance when items are separated in both space and time. We report two experiments that differed in whether color or location was the tested feature. In each experiment, we measured EEG alpha-band power while participants memorized the target feature of two sequentially presented colored dots. We then applied an inverted encoding model to the topography of oscillatory alpha-band power (8-12 Hz) on the scalp to measure how long the location of each item was attended. In Experiment 1, participants performed a delayed color estimation task, and we found that patterns of alpha-band power tracked the location of the most recently presented item. In Experiment 2, participants performed a delayed spatial estimation task, and we found that patterns of alpha-band power tracked the location of Item 1 for longer than observed in Experiment 1. However, only the most recently presented item (Item 2) sustained until the end of the delay. Taken together, our results show that, although both items need to be remembered, covert spatial attention prioritizes items one at a time when they are displayed in a sequence.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-15"},"PeriodicalIF":3.0,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149076140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proposed mechanisms include \"boosting,\" where LTM enhances WM representations through additional activation but does not reduce WM load; \"chunking,\" where WM holds references to LTM, reducing WM load; and \"offloading,\" where LTM substitutes active maintenance in WM. To distinguish between these mechanisms, we measured the contralateral delay activity (CDA) and behavioral performance during a three-alternative forced-choice WM task, in which some trials (varying in memory array set size) included a prelearned color-object binding. The CDA is a well-established neural correlate that indexes the amount of information actively stored in WM, allowing us to distinguish between the three accounts by examining whether including prelearned bindings in a memory set of a given size reduced its amplitude compared with maintaining entirely new bindings. Overall, our findings supported the boosting account. Prelearned bindings improved performance for matching items in WM, but the benefit did not extend to newly encoded items, indicating no reduction in WM load. CDA amplitude increased with set size irrespective of whether the items were prelearned or new, reflecting active maintenance of all the to-be-remembered items. Overall, these results show that prelearned associations in LTM can boost WM performance without substituting for WM storage, providing evidence against offloading or chunking accounts in the context of our paradigm.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-14"},"PeriodicalIF":3.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148984210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a \"property-cluster-category\" organization that bridges object conceptual dimensions and discrete category areas in the HVC. Using a large-scale naturalistic stimulus data set and voxel-wise encoding methods, we analyzed the encoding patterns of a low-dimensional abstract property space and identified distinct brain clusters with shared cortical property profiles. These clusters broadly aligned with category-selective areas, suggesting that category regions can be understood as local peaks within a continuous property topology. We further tested whether this visual organization could emerge in a visual-only Topographic Deep Artificial Neural Network trained without semantic supervision. The model recapitulated property tuning for physical and biological dimensions but showed weaker affective tuning, suggesting that affective dimensions may require embodied or nonvisual experience. Finally, model-based lesion and stimulation analyses showed that Topographic Deep Artificial Neural Network units aligned with brain clusters contributed selectively to object classification. Together, these results provide a framework for understanding how the continuous property topology and discrete category selectivity are jointly organized in the human HVC, and suggest that abstract visual properties-which shape this topological organization-can be learned in part from statistical regularities in visual input.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-18"},"PeriodicalIF":3.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148984245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous work has largely relied on unisensory paradigms, leaving open the question of how attentional mechanisms act on audiovisual working memory representations. Here, using an EEG-based audiovisual delayed-match-to-sample task, we investigate whether attention to audiovisual working memory contents operates on the level of individual unisensory features or bound cross-modal objects. On each trial, participants memorized an audiovisual item. At test, they were randomly presented with either an auditory, visual, or audiovisual probe stimulus and indicated whether the latter matched their working memory content. Compared with recalling the entire audiovisual object, recall of unisensory visual or auditory features resulted in poorer behavioral performance and elevated midfrontal theta power. Multivariate pattern analyses (MVPAs) showed that task-irrelevant feature representations were retrieved in both auditory and visual probe trials, consistent with object-based retrieval. Moreover, these results shed light on the representational structure underlying cross-modal feature storage in working memory, suggesting that audiovisual features are stored as bound objects and that attentional selection of individual object features in one modality spreads to cross-modal object features in another modality. In task conditions where such incidental recall of task-irrelevant features is detrimental to task performance, this places greater demands on cognitive control mechanisms.","PeriodicalId":51081,"journal":{"name":"Journal of Cognitive Neuroscience","volume":" ","pages":"1-16"},"PeriodicalIF":3.0,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148984226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
