These processes must work in concert to enable individuals to orient themselves and locomote to goal locations, but it remains unclear whether proficiency in one type of spatial processing necessarily implies proficiency in other forms of spatial processing during navigation. Here, we study the processes of transforming a map-indicated viewpoint to locate and move to surrounding invisible targets in a simple open arena. Participants (n = 210) performed a novel immersive Viewpoint Transformation Task (iVTT, He et al., 2022), a map-based navigation task in a virtual environment in which people first viewed a map of an environment from a top-down perspective, then physically walked to a goal location (specified on the map) in an immersive virtual environment, using a first-person perspective. We examined the effects of spatial perspective taking (using the Spatial Orientation and Money Roadmap Tasks) and path integration (using the Triangle Completion Task) on individual differences in task performance. In a regression analysis, a measure of perspective taking and a measure of path integration independently predicted iVTT performance. Notably a small number of participants (5%) exhibited difficulty with the initial perspective taking step. Our results suggest that both the ability to assume a different perspective to plan movement and the use of path integration to update one's position while executing the movement contribute to effectively utilizing map-based information during navigation.</p>","PeriodicalId":19279,"journal":{"name":"Neuropsychologia","volume":" ","pages":"109476"},"PeriodicalIF":2.0,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856777","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}

In order to perform actions in a timely fashion, it is necessary to anticipate the timing at which events occur, but also what event is more likely than the other. While EEG signatures of anticipation have been identified it is less clear whether classifiers trained on informative (cued) trials generalize to uncued trials and whether such decoded templates predict trial-by-trial shifts in decision strategy (e.g., drift-rate or starting-point changes in a Diffusion Decision Model). This study aimed to determine whether human participants anticipated a visual or auditory stimulus at the single-trial level in both cued and uncued trials. We found that pre-stimulus brain activity contains information about the expected upcoming stimulus and that this information can be successfully extracted from single-trial brain activity. Behavioral analyses revealed a connection between correct anticipation and shifts in decision strategy, while also validating the classification of uncued trials. Importantly, the classification of uncued trials confirms that expectations build even in the absence of triggers.

The current study aimed to test this question by examining the neural underpinnings of attentional filtering with age. Young and older adults were presented with either positive (target-matching), negative (distractor-matching), or neutral cues, which were immediately followed by a search array in which participants had to report the orientation of a search target. We found that both age groups appropriately attended to target information when given a target-matching pre-cue, as indicated by faster response times (RTs) and a significant N2pc event-related potential (ERP) related to increased attentional selection. However, only young adults showed suppression of distractors, as indicated by a significant distractor-positivity (P_D) ERP following all three cue types. Older adults did not show significant suppression of distractors in any condition and, they even showed increased attention towards distractors following negative and neutral cues.

To address this gap, I employed connectome-based predictive modeling (CPM) to analyze resting-state functional connectivity patterns in a large sample of healthy college students. The results revealed two key neural signatures: (1) a positive network characterized by connections between the salience network (SAN) and medial frontal regions (MF), and (2) a negative network comprising intra-SAN connections and links between the default mode network (DMN) and other networks (e.g., SAN, MF). These findings suggest that IT formation engages integrated affective, cognitive, and social cognitive processes. Moreover, the IT-happiness association was mediated by the strength of the positive network, hinting enhanced social support processing and cognitive control as potential neural mechanisms.

One such indicator is the speed of visual information transfer across the splenium of the corpus callosum, also known as inter-hemispheric transfer time (IHTT). We quantified IHTT in adults with mTBI and demographically-similar control participants at an initial assessment approximately 3-4 weeks after injury and again at follow-up about 10 months later. The analytic sample comprised 94 participants between the ages of 18 and 45 years, including 48 with mTBI (24 female) and 46 demographically-similar controls (22 female). IHTT was quantified directly using the P1 and N1 components of the scalp-recorded brain event-related potential (ERP). In a subset of 19 participants with mTBI (seven female) and 19 control participants (seven female), we also quantified the integrity of white matter in the corpus callosum using fractional anisotropy (FA) values derived from diffusion-tensor magnetic resonance imaging (DTI), along with volumetric measures of the corpus callosum. Participants with mTBI showed slower early visual transfer (P1 IHTT) at both initial and ten-month follow-up time points, whereas later processing (N1 IHTT) did not differ between groups. Fractional anisotropy (FA) MRI values generally showed lower FA across the corpus callosum in individuals with mTBI compared to controls, consistent with altered white matter microstructure. No volumetric differences were observed between groups or over time.

While volume loss is well-documented, surface-based morphometric (SBM) features-curvature, gyrification, and thickness-remain less explored. Using T1-weighted MRI data from the Alzheimer's Disease Neuroimaging Initiative (3144 timepoints; CN: 450, MCI: 284, AD: 204), hippocampal subfields were analyzed with HippUnfold. Linear mixed effects models examined volume and SBM changes, tracking cognitive trajectories in stable (n = 710) and progressing (n = 228) individuals. Focusing on CA1 as a representative subfield, baseline volume differed significantly across diagnostic groups, with all clinical groups showing reduced volume relative to cognitively normal individuals, consistent with disease severity. In contrast, surface-based morphometry (SBM) measures showed minimal baseline group differences, with only the CN to MCI/AD group exhibiting a significant negative main effect across SBM metrics. Longitudinal analyses revealed that disease-related changes were primarily captured by time-dependent interactions. In particular, the MCI to AD group demonstrated the most robust longitudinal changes, showing the largest magnitude of volume loss and accompanying SBM alterations over follow-up. Individuals progressing from CN to MCI/AD exhibited similar, though slightly smaller, longitudinal SBM changes, indicating early surface remodeling prior to overt clinical progression. In contrast, Stable AD showed significant longitudinal effects only for volume loss, and Stable MCI displayed minimal or nonsignificant SBM and volumetric changes. Analyses linking longitudinal morphometric change to cognitive domains was differentially associated with rates of cognitive decline across domains and disease stages, with SBM changes linked to slower language decline in early stages and to accelerated memory and visuospatial decline during progression from MCI to AD. While hippocampal volume loss remains a robust marker of AD, it does not fully capture longitudinal morphometric changes associated with disease progression. In particular, SBM measures showed their strongest and most consistent longitudinal effects in individuals progressing from MCI to AD, where changes in surface geometry accompanied accelerated volume loss.
