Specifically, compared with the instructor-absent condition, under autonomy-supportive teaching, instructor presence decreased retention and concentration, but did not affect extraneous load; under controlling teaching, instructor presence did not impact retention, but damaged concentration and boosted extraneous load; under neutral teaching, instructor presence promoted retention without affecting concentration or extraneous load. Conclusions: The findings imply that the facilitating effect of instructor presence as a social cue and its detrimental effect as a seductive detail can dominate one another or cancel each other out under specific motivating styles.

An abundance of research has therefore examined how we learn to prevent distraction by salient stimuli. There is growing consensus that salient stimuli can be suppressed to mitigate distraction. However, many questions about distractor suppression have been difficult to resolve in typical studies that use small sample sizes. The current study is a pooled analysis of several previous eye-tracking studies (N = 354) which resulted in a large data set of more than a half-million eye movements. This large data set was used to uncover new findings that improve our understanding of the attentional processes involved in distractor suppression. We also evaluated several new findings related to how attentional suppression is learned and is influenced by selection history. Altogether, these findings highlight the need for a hybrid model of attention that includes both bottom-up and top-down components. Moreover, this large publicly available dataset can be used by future research to investigate other questions related to attentional capture and distractor suppression.},

The current study utilized pupillometry to assess automatic psychophysiological responses to others' painful facial expressions in both adults and children (N = 72). Results revealed that pupil size significantly increased when perceiving painful versus neutral expressions, independent of low-level visual features. Notably, both adults and children exhibited a racial in-group bias, with pupil dilation effects observed only for same-race painful faces. Furthermore, individuals' Autism Spectrum Quotient scores were negatively correlated with pupil dilation effects toward painful expressions of same-race faces. These findings suggest that pupillary responses might reflect automatic empathic arousal to others' pain and are modulated by racial group membership and autistic traits, providing a potential physiological indicator, at least at the group level, for probing affective resonance in children or individuals with socio-cognitive disorders (e.g., autism spectrum disorder).},

Results revealed that: (1) Both high- and low-security individuals exhibited attentional biases toward emotional faces compared to neutral faces. (2) Security levels modulated attention to emotional faces: high-security individuals displayed greater bias toward happy faces, while low-security individuals showed enhanced bias toward angry faces, consistent with the schema-congruence hypothesis. (3) Reaction times accelerated under threat conditions for all participants, and threat contexts amplified attentional bias toward angry faces in high-security individuals. These findings highlight the interplay between intrinsic security and external contexts in shaping attentional processing of emotional stimuli.},

However, the attentional effect preceding saccadic eye movements, a critical component of natural vision, remain understudied.

This study investigated how eye-movement features predict delivery accuracy and distinguish elite from novice athletes. Thirty wheelchair curling athletes (15 experts, 15 novices) performed standardized delivery accuracy and visual search tasks, with eye movements recorded using the EyeLink Portable Duo system. We employed multiple regression to identify predictors of accuracy and a support vector machine (SVM) to classify athletes based on expertise. Experts demonstrated superior delivery accuracy and significantly more efficient visual search patterns, characterized by shorter dwell times, faster reaction times, and fewer fixations. The SVM model successfully classified athletes with 90% accuracy (AUC = 0.93), while regression analysis confirmed that specific gaze metrics were robust factors associated with performance. These findings establish a strong quantitative link between efficient gaze strategies and expert motor performance in a constrained-mobility setting. This integrated eye-tracking and machine learning approach offers a powerful framework for objectively evaluating performance and developing data-driven, personalized training interventions in wheelchair curling and other precision-focused adaptive sports.},

Furthermore, in offline tasks, the three-year-old group features a high choice randomness and the four-to-five- year-olds show the longest reaction time. Therefore, we argue that, not only age but also metonymy type can influence metonymy acquisition, and that a lack of socio-cultural experience can be a source of acquisition difficulty for children under six. Methodologically speaking, we believe that online methods should not be considered superior to offline ones as they investigate different aspects of implicit and explicit language comprehension.},

Surprisingly, participants actively avoided directing eye movements towards the distractor. Still, salient distractors increased both search errors, which were committed when the target was never fixated, and decision errors, which were committed when the target was fixated but not detected. Our results demonstrate that salient distractors trigger early quitting by reducing the amount of information that observers extract from the search image and disrupting search guidance.},

In this paper, we examined the effects of pupil size variations on eye-tracking data quality in four head-mounted eye trackers: the Pupil Core, the Pupil Neon, the SMI ETG 2w, and the Tobii Pro Glasses 2, in addition to a widely used desktop eye tracker, the SR Research EyeLink 1000 Plus. Participants viewed a central target on a monitor while we systematically varied the screen brightness to induce controlled pupil size changes. All head-mounted eye trackers exhibited PSA, with apparent gaze shifts ranging from 0.94 formula presented for the Pupil Neon to 3.46 formula presented for the Pupil Core. Except for the Pupil Neon, all eye trackers exhibited a significant change in accuracy due to pupil size variations. Precision measures showed device-specific effects of pupil size changes, with some eye trackers performing better in the bright condition and others in the dark condition. These findings demonstrated that, just like desktop eye trackers, head-mounted video-based eye trackers exhibited PSA.},

Here we used a transcranial magnetic stimulation (TMS) perturbational approach by applying brief 10 Hz TMS to early visual areas (EVAs) or the medio-temporal (MT) area in healthy participants while recording concurrent functional magnetic resonance imaging (fMRI). TMS delivered during the early stages of motion processing specifically impaired direction discrimination at both sites,whereas disruption of the later processing phase impaired performances only for the MT condition. Despite a similar local increase in BOLD activity induced by EVA and MT stimulation, the broader network responses diverged significantly. Perturbation ofEVA elicited a more robust and efficient pattern of functional reorganization, manifesting as more constrained BOLD changes, consistent with greater resilience to focal disruption. In contrast behavioural impairments induced by MT stimulation were accompanied by a disorganized and less-efficient network configuration, characterized by smaller small-world properties and longer path lengths. The decrease in performances induced by MT stimulation scaled with lower clustering coefficients, implying a more random or decentralized network structure. These findings demonstrate that TMS-fMRI coupling provides a powerful framework for causally mapping the relationships between local neural perturbations, large-scale network dynamics and behavioural performance.},

Here we used a transcranial magnetic stimulation (TMS) perturbational approach by applying brief 10 Hz TMS to early visual areas (EVAs) or the medio-temporal (MT) area in healthy participants while recording concurrent functional magnetic resonance imaging (fMRI). TMS delivered during the early stages of motion processing specifically impaired direction discrimination at both sites,whereas disruption of the later processing phase impaired performances only for the MT condition. Despite a similar local increase in BOLD activity induced by EVA and MT stimulation, the broader network responses diverged significantly. Perturbation ofEVA elicited a more robust and efficient pattern of functional reorganization, manifesting as more constrained BOLD changes, consistent with greater resilience to focal disruption. In contrast behavioural impairments induced by MT stimulation were accompanied by a disorganized and less-efficient network configuration, characterized by smaller small-world properties and longer path lengths. The decrease in performances induced by MT stimulation scaled with lower clustering coefficients, implying a more random or decentralized network structure. These findings demonstrate that TMS-fMRI coupling provides a powerful framework for causally mapping the relationships between local neural perturbations, large-scale network dynamics and behavioural performance.<\/div>

Participants discriminated targets occurring after one of 32 different face\u2013object cue pairs, which varied in the degree of attractiveness. Experiment 1 measured covert social attention in manual responses while maintaining central fixation. No evidence of attentional preference for faces was found. Experiment 2 measured overt social attention in eye movements while maintaining natural viewing conditions. A reliable oculomotor preference for attractive faces was found. Thus, facial attractiveness affects covert and overt social attention differently, reflecting the diverging ways in which faces affect attention with respect to social functioning in daily life.

The current study examines how each of these effects independently develops in response to novel stimuli. In short blocks participants completed a search for a pre-defined target shape. Each block the colour of the target and the distractor were randomized so that the initial and subsequent attentional adaptations to these features could be assessed (via eye-tracking). These mini-blocks reveal substantial information about the development of the inhibition effect.

Furthermore, the effect emerged even if it was the first presentation of the distractor feature. Gaze analysis concurs with this, eyes avoided the distractor when the target feature was known, but the distractor feature unknown. This shows compelling evidence for guidance from target-feature enhancement. However, some evidence for distractor-feature suppression is observed, further oculomotor suppression of the distractor is seen after its initial presentation. Together, the current results show that the inhibition effect develops rapidly in visual search displays, and that while a large portion of the effect can be accounted for by target-enhancement, distractor-suppression may still have a role in influencing attentional allocations.},

In some visual search scenarios, the presence of a singleton distractor leads to faster search performance. This has been coined as the inhibition effect and is believed to represent avoidance of the singleton distractor.

\r\nabstract = {Infant face recognition shows plasticity, with recent evidence indicating enhancement by the presence of emotional facial expressions. The mechanisms and domain-generality of this effect remain largely unknown. This study tested whether auditory emotional cues (vocalizations) facilitated infants' recognition of other-race faces, a perceptual challenge during the first year of life. Infants (N = 89) were presented with emotionally neutral faces paired with happy, sad, or neutral vocal sounds in a within-subjects design. Experiment 1 assessed recognition using identical face images between the familiarization and test phases, while Experiment 2 examined face recognition across viewpoint changes. Across both experiments, infants exhibited successful face recognition only when they were learned with emotional sounds (happy and sad). This facilitative effect remained stable across the tested age range and did not differ between happy and sad vocalizations. Infants' eye movement data revealed comparable face-looking patterns across conditions, suggesting that the facilitation was not driven by changes in visual attention. Thus, incidental, cross-modal emotional signals significantly enhance infant face recognition. This underscores the early integrative nature of emotion processing and its catalytic role in cognitive development.},

Such temporal anticipation is critical over wide timescales, and especially salient over the range from hundreds of milliseconds to a few seconds. Despite advances in our understanding of basic timing behavior and its underlying neural mechanisms, it remains an open question whether anticipation is stable across these short time scales. Recent work shows that the brain models the probability density function (PDF) of events across time, suggesting a canonical mechanism for temporal anticipation. Here, we investigate whether this computation holds when the event distribution covers different time spans. We show that, irrespective of the time span, anticipation, measured as reaction time, scales with the event distribution. This demonstrates that the key computation\u2014the estimation of event probability density\u2014is invariant across temporal scales. We further show that the precision of anticipation is also scale invariant which contradicts Weber's law. The results are established in vision and audition, suggesting that the core computations in temporal anticipation are independent of sensory modality. Perceptual systems exploit probability estimation over time independently of temporal scale to anticipate imminent events.},

Recent empirical studies proposed an emotional motivation account to explain the ending effect. That is, the pursuit of an emotionally satisfying ending leads to the increase of risk-taking. However, previous studies have mostly examined the ending effect at the behavioral level, there is yet no physiological evidence to examine the emotional motivation account. To fill in this gap of knowledge, the current study examined the emotional motivation account at the physiological level by recording pupil diameters, which reflect the activation of emotional motivation. Participants were randomly assigned to complete eight rounds or ten rounds of risk decision tasks while having their eyes tracked. The results showed a significant interaction between round and group on pupil diameter. Specifically, there was no significant difference between the first six rounds and the 8th round in the experimental group. For the control group, the pupil diameter of the first six rounds was significantly larger than the 8th round. Perceived end- ing may have sustained emotional arousal. This finding provides qualified physiological support for the emotional motivation account of the ending effect.},

Additionally, the results confirmed the mediating role of novelty and highlighted architectural authenticity as a moderator in this effect. These insights enhance our understanding of aesthetic preferences for tourism architecture among tourists with different self-construals and provide practical recommendations for tourism industry to tailor specific architectural shapes to increase tourists' travel intentions.},

Here, we investigate how motor cortical dynamics adapt to dynamic environments and whether these adaptations influence robustness against disruptions. We apply intracortical microstimulation (ICMS) in the motor cortex of monkeys performing delayed center-out reaches to either a static target (static) or a rotating target (moving) that required interception. While ICMS prolongs reaction times (RTs) in the static condition, it does not increase RTs in the moving condition, correlating with faster recovery of neural population activity post-perturbation. Neural dynamics suggests that the moving condition involves ongoing sensorimotor transformations during the delay period, whereas motor planning in the static condition is completed shortly. A neural network model shows that continuous feedback input rapidly corrects perturbation-induced errors in the moving condition. We conclude that continuous sensorimotor transformations enhance the motor cortex's resilience to perturbations, facilitating timely movement execution.},

However, there is a lack of public datasets that provide simultaneous multiple modalities during a visual-motor task. Functional near-infrared spectroscopy and electroencephalography to record brain activity simultaneously facilitate more precise capture of the complex visuomotor of brain mechanisms. Additionally, by employing a combined eye movement and manual response, it is possible to fully evaluate the effects of visuomotor outputs from implicit and explicit dimensions. We recorded whole-brain EEG (34 electrodes) and fNIRS (44 channels) covering the frontal and parietal cortex along with eye movements, behavior sampling, and operant behavior. The dataset underwent rigorous synchronization, quality control to highlight the effectiveness of our experiments and to demonstrate the high quality of our multimodal data framework.},

Using a visuo-vestibular decision-making task, here we show the subcortical caudate nucleus (CN) of male primates displays distinct population code compared to association cortices along the modality dimension. Specifically, in a low-dimensional state subspace, neural trajectory in the frontal and posterior-parietal association cortical activity during multimodal-stimulus condition evolves along the visual trajectory, whereas along the vestibular trajectory in the CN. We then show CN population activity is consistent with the animal's behavioral strategy employed within a generalized drift-diffusion framework. Importantly, causal-link experiments, including application of GABAa-receptor agonist, D1-receptor antagonist, and electrical microstimulation, further confirmed CN's critical contributions to perceptual behavior. Our results confirm CN's vital importance to decision making in complex environments with multimodal information.},

Why sleep deprivation has such profound effects on cognition is not well understood. Here we use simultaneous fast fMRI\u2013EEG to test how sleep deprivation modulates cognitive, neural and fluid dynamics in the human brain. We demonstrate that attentional failures during wakefulness after sleep deprivation are tightly orchestrated in a series of brain\u2013body changes, including neuronal shifts, pupil constriction and cerebrospinal fluid (CSF) flow pulsations, pointing to a coupled system of fluid dynamics and neuromodulatory state. CSF flow and hemodynamics are coupled to attentional function within the awake state, with CSF pulsations following attentional impairment. The timing of these dynamics is consistent with a vascular mechanism regulated by neuromodulatory state. The attentional costs of sleep deprivation may thus reflect an irrepressible need for rest periods driven by a central neuromodulatory system that regulates both neuronal and fluid physiology.},

Here we examined whether fixating on diagnostic features of emotional expressions\u2014such as eye region for fear and the mouth for happiness\u2014affects saccadic targeting and improves recognition accuracy. Across two pre-registered experiments, participants viewed fearful, happy, and neutral faces for short intervals (50 or 150 ms) while the initial fixation location was manipulated. Although such brief stimulation does not allow for visual exploration, the faces still elicited reflexive saccades that occurred after stimulus offset. These saccades were modulated by the emotional expressions indicating a consistent preferential saccadic orienting towards diagnostic features, even with limited exposure. As this effect disappeared for inverted faces, it can be attributed to an extrafoveal processing of facial features instead of an attentional orienting towards physically salient image regions. Participants' recognition accuracy was unaffected by the foveated facial feature, but this observation might also be due to ceiling effects in performance. Collectively, these findings contribute to understanding the attentional mechanisms of feature-based processing in the perception of emotional facial expressions.},

The use of peripheral vision was established by eye-tracking. Both the face specific N170 component and the subsequent Early Posterior Negativity (EPN) were enhanced by fear at the cue level, yet the latter one only when fear was goal relevant. Importantly, we found that early on following target onset at the P1 level, both value and goal relevance drove spatial attention and interacted with each other such that when they were goal-relevant, fearful faces captured attention less than when they were not. These results suggest that emotional attention is flexible and it can be influenced by the goal relevance of emotion. Moreover, they shed light on the electrophysiological manifestations of this flexibility and dovetail with the assumption that sensory gain control effects occurring in the visual cortex depending on attentional control are multiplexed and determined by both value and goal.},

\r\nabstract = {Visual search becomes slower with aging, particularly when targets are difficult to discriminate from distractors. Multiple distractor rejection processes may contribute independently to slower search times: dwelling on, skipping of, and revisiting of distractors, measurable by eye-tracking. The present study investigated how age affects each of the distractor rejection processes, and how these contribute to the final search times in difficult (inefficient) visual search. In a sample of Dutch healthy adults (19\u201385 years), we measured reaction times and eye-movements during a target present\/absent visual search task, with varying target-distractor similarity and visual set size. We found that older age was associated with longer dwelling and more revisiting of distractors, while skipping was unaffected by age. This suggests that increased processing time and reduced visuo-spatial memory for visited distractor locations contribute to age-related decline in visual search. Furthermore, independently of age, dwelling and revisiting contributed stronger to search times than skipping of distractors. In conclusion, under conditions of poor guidance, dwelling and revisiting have a major contribution to search times and age-related slowing in difficult visual search, while skipping is largely negligible.},

Pupillometry studies show distinct pupillary changes for WM stages, reflecting cognitive effort and load. Motivational incentives enhance WM performance by potentially improving encoding, maintenance, or retrieval, though the specific components influenced by reward remain unclear. This study specifically tested whether reward modulates cognitive control processes during WM maintenance using pupillometry. Participants performed a delayed-estimation orientation WM task with reward cues indicating reward levels at the beginning of trials. The results revealed that motivational incentives significantly improved WM performance and increased pupillary dilation during maintenance. These findings provide evidence for the modulation of WM maintenance by reward through enhanced top-down cognitive control processes.},

We evaluated three markers of social processing: social perception via the ERP N170 Latency to Upright Faces; social attention via the Eye Tracking (ET) OMI (Oculomotor Index of Gaze to Human Faces) that captures percent looking to faces from three tasks; and social cognition via the NEPSY Face Memory task.

Results: Adjusting for baseline performance, time between measurements, age, and sex, our results suggest differential prognostic relations for each of the markers. The ERP N170 Latency to Upright Faces showed limited prognostic relations, with a significant relation to short term changes in face memory. The ET OMI was related to face memory over both short and long term. Both the ET OMI and Face Memory predicted long-term autistic social behavior scores. Conclusions: In the context of a large-scale, rigorous evaluation of candidate markers for use in future clinical trials, our primary markers had significant but small-effect prognostic capability.

Theoretical accounts of action control assume a pre-activation of action-effects prior to action execution. Here we show that when participants were asked to report the time of their voluntary keypress using the position of a fast-rotating clock hand, a predictable action-effect (i.e. a 250 ms delayed sound after keypress) led to a shift of visuospatial attention towards the clock hand position of action-effect onset, thus demonstrating an influence of action-effects on action representation. Importantly, the attention shift occurred about 1 second before the action execution, which was further preceded and predicted by a lateralisation of alpha oscillations in the visual cortex. Our results indicate that when the spatial location is the key feature of action-effects, the neural implementation of the action-effect pre-activation is achieved through alpha lateralisation.},

This study presents single- and multiunit recordings from the human lateral occipital complex (LO), a key region for shape and object recognition, during three distinct perceptual paradigms: backward masking, flash suppression and binocular rivalry. Stimulus awareness increased decoding accuracy and decoders assigned higher probabilities to the consciously perceived stimulus during periods of dichoptic stimulus presentation. These findings highlight the intricate neural mechanisms underlying visual awareness and show that LO responses predominantly align with subjective phenomenology, offering new insights into the neural correlates of visual consciousness.},

Performance improves at cued locations and worsens at uncued locations compared to distributed attention, demonstrating a selective processing tradeoff. Pre-target BOLD responses in cortical visual field maps reveal two key changes: First, a stimulus-independent baseline shift, with increases near cued locations and decreases elsewhere, paralleling behavioral results. Second, a shift in population receptive field centers toward the attended location. Both effects increase in higher visual areas. Together, these findings reveal that spatial attention has large effects on visual cortex prior to target appearance, altering neural response properties across multiple visual field maps and enhancing performance through anticipatory mechanisms.},

Across three experiments, we examined how implicit racial attitudes and self-reported individuating experiences influenced gaze patterns when participants evaluated their liking of these paintings. Despite no requirement to inspect faces in the paintings, the results revealed that participants with negative implicit attitudes toward other-race individuals and limited individuating experience with those groups, spent more time fixating on other-race faces. This relationship between implicit attitudes and individuating experience in guiding gaze behaviour was consistent across both British and Chinese participants, despite differing definitions of same- and other-race faces between the groups. Our findings suggest that gaze behaviour during the aesthetic evaluation of figurative paintings is shaped by an interaction between attitudinal and experiential factors, which operates across cultural contexts.},

We found a dominant role of the ventral stream in representing face-related gaze tracks, starting from the orbitofrontal cortex (OFC) and anterior temporal lobe (ATL), and extending to the medial temporal and ventral occipitotemporal cortex. Our findings show that the ventral pathway represents the gaze tracks used to explore faces, by which top-down prediction of face category in OFC and ATL may guide, via the medial temporal cortex or directly, face perception in the ventral occipitotemporal cortex.},

Here, we investigate the neural processes that regulate decision-making and metacognition under speed pressure using time-resolved analyses of brain activity recorded using electroencephalography. Participants performed a motion discrimination task under short and long response deadlines and provided a metacognitive rating following each response. Behaviourally, participants were faster, less accurate, and showed superior metacognition with short deadlines. These effects were accompanied by a larger centro-parietal positivity (CPP), a neural correlate of evidence accumulation. Crucially, post-decisional CPP amplitude was more strongly associated with participants' metacognitive ratings following errors under short relative to long response deadlines. Our results suggest that superior metacognition under speed pressure may stem from enhanced metacognitive readout of post-decisional evidence.},

We demonstrate that (1) the neural representation of one feature (the position of an object) in visual area V4 is orthogonal to those of several background features, (2) the ability of human observers to precisely judge object position was largely unaffected by those background features, and (3) many features of the object and the background (and of objects from a separate stimulus set) are orthogonally represented in V4 neural population responses. Our observations are consistent with the hypothesis that orthogonal neural representations can support stable perception of object features despite the richness of natural visual scenes.<\/div>

\r\nabstract = {The premotor theory of attention suggests that both overt and covert attentional orienting are governed by similar mechanisms and neural structures, a concept extensively investigated in paradigms involving shifts in attention and gaze towards peripheral targets. Previous studies have found a strong link between cortical alpha oscillations and overt smooth pursuit of a target. However, the relationship between alpha oscillations and covert tracking of peripheral moving stimuli remains unclear. To address this, we asked 16 observers to maintain fixation while covertly attending to a visual stimulus moving along the horizontal meridian at varying speeds (2, 6, or 12 \u00b0\/s), within either the left or right hemifield. We simultaneously recorded both eye movements and EEG data. Our results revealed that alpha power was significantly reduced when observers tracked a target that moved further in the periphery, independent of its speed. These findings confirm that the distribution of alpha power is sensitive to the allocation of covert attention during tracking. This suggests a tight link between the attentional processes involved in covert tracking and overt pursuit of a moving target, supporting the premotor theory of attention.},

A century of psychophysical studies has produced conflicting evidence: retinotopic, egocentric, world-centric, or even object-centric. We introduce a hierarchical Bayesian model mapping retinal velocities to perceived velocities. Our model mirrors the structure in the world, in which visual elements move within causally connected reference frames. Friction renders velocities in these reference frames mostly stationary, formalized by an additional delta component (at zero) in the prior. Inverting this model automatically segments visual inputs into groups, groups into supergroups, progressively inferring structured reference frames and \u201cperceives\" motion in the appropriate reference frame. Critical model predictions are supported by two experiments, and fitting our model to the data allows us to infer the subjective set of reference frames used by individual observers. Our model provides a quantitative normative justification for key Gestalt principles providing inspiration for building better models of visual processing in general.},

For implicitly spatial words such as \u201cROOF\u201d or \u201cBASEMENT\u201d, it was recently shown that processing both the cue word and a subsequent spatial target stimulus was necessary for spatial congruity effects to emerge. Here we challenge this work by documenting that word cues alone suffice to induce congruity effects if they are processed deeply. Sixty-three healthy adults detected vertically displaced targets after looking at centrally presented cue words under three counterbalanced instructions, imposing increasing processing depth: Lexical decision, non-spatial categorization, and spatial categorization. Target detection speed revealed spatial congruity effects for both spatial and non-spatial categorization but not for lexical decision. An interpretation in terms of covert attention deployment was corroborated by concomitant vertical displacements of eye gaze. Our results reveal minimal requirements for covert and overt semantic cueing of spatial attention.},

Increasing evidence suggests that serial order in verbal WM is spatially coded and that spatial attention is involved in access and retrieval. Based on the idea that brain areas controlling spatial attention are also involved in oculomotor control, we used eye tracking to reveal how the spatial structure of serial order information is accessed in verbal working memory. In two experiments, participants memorized a sequence of auditory words in the correct order. While their eye movements were being measured, they named the memorized items in a self-determined order in Experiment 1 and in a cued order in Experiment 2. We tested the hypothesis that serial order in verbal working memory interacts with the spatial attention system whereby gaze patterns in visual space closely follow attentional shifts in the internal space of working memory. In both experiments, we found that the gaze shifts in visual space correlated with the spatial shifts of attention along the left-to-right one-dimensional mapping of serial order positions in verbal WM. These findings suggest that spatial attention is employed for dynamically searching through verbal WM and that eye movements reflect the spontaneous association of order and space even in the absence of visuospatial input.},

In the current work, the influence of sequence learning on the oculomotor system was investigated by testing 20 healthy adults for 3\u00a0days as they practiced an implicit motor learning task, the serial targeting task (STT). The STT contained a repeated sequence, which was interleaved with random sequences. This task was practiced on a KINARM robot that tracked both saccades and reaches. A delayed, 24-h retention test assessed sequence-specific motor learning. Sequence-specific changes across practice and learning were observed for both saccades and reaches; this was demonstrated by faster saccade and arm motor reaction times for the repeated sequence compared to random sequences. Notably, change in the oculomotor system occurred earlier in practice as compared to the manual motor system. Reaches were executed more quickly when led by express saccades (rapid eye movements occurring within 90\u2013120\u00a0ms) compared to when they were preceded by regular latency (> 120\u00a0ms) saccades early in practice. Our findings highlight distinct yet interconnected functions between oculomotor and manual motor systems associated with implicit motor sequence learning.},

\r\nabstract = {Visual search is crucial in daily human interaction with the environment. Hybrid search extends this by requiring observers to find any item from a given set. Recently, a few models were proposed to simulate human eye movements in visual search tasks within natural scenes, but none were implemented for Hybrid search under similar conditions. We present an enhanced neural network Entropy Limit Minimization (nnELM) model, grounded in a Bayesian framework and signal detection theory, and the Hybrid Search Eye Movements (HSEM) Dataset, containing thousands of human eye movements during hybrid tasks. A key Hybrid search challenge is that participants have to look for different objects at the same time. To address this, we developed several strategies involving the posterior probability distributions after each fixation. Adjusting peripheral visibility improved early-stage efficiency, aligning it with human behavior. Limiting the model's memory reduced success in longer searches, mirroring human performance. We validated these improvements by comparing our model with a held-out set within the HSEM and with other models in a separate visual search benchmark. Overall, the new nnELM model not only handles Hybrid search in natural scenes but also closely replicates human behavior, advancing our understanding of search processes while maintaining interpretability.},

Leveraging deep learning algorithms that extract body poses from videos of behaving monkeys, applied to a monkey avatar, we investigated neural tuning for pose and viewpoint, targeting fMRI-defined mid and anterior Superior Temporal Sulcus (STS) body patches. We modeled the pose and viewpoint selectivity of the units with keypoint-based principal component regression with cross-validation and applied model inversion as a key approach to identify effective body parts and views. Mid STS units were effectively modeled using view-dependent 2D keypoint representations, revealing that their responses were driven by specific body parts that differed among neurons. Some anterior STS units exhibited better predictive performances with a view-dependent 3D model. On average, anterior STS units were better fitted by a keypoint-based model incorporating mirror-symmetric viewpoint tuning than by view-dependent 2D and 3D keypoint models. However, in both regions, a view-independent keypoint model resulted in worse predictive performance. This keypoint-based approach provides insights into how the primate visual system encodes socially relevant body cues, deepening our understanding of body pose representation in the STS.},

Such loss can significantly impact daily life activities, compromising tasks such as reading, navigating or driving. Although slow and labour intensive, evidence suggests that early interventions with tailored rehabilitation programmes might stimulate visual recovery and improve quality of life in stroke survivors.To enhance the effects of such rehabilitation programmes, we designed a novel, non-invasive, pathway-specific, physiology-inspired cross-frequency brain stimulation protocol, where complex oscillatory signal integration was inferred from phase\u2013amplitude coupling of oscillatory signals between the primary visual cortex and the motion-sensitive medio-temporal area. Sixteen stroke patients were enrolled in a double-blind, randomized, cross-over trial, during which they performed two blocks of 10 daily training sessions of a direction discrimination task, combined with one of the two cross-frequency transcranial alternative brain stimulation (cf-tACS versus control cf-tACS) conditions.We found that the cf-tACS condition promoting feedforward visual inputs to the medio-temporal area significantly enhanced motion discrimination performance and shifted visual field borders (i.e. through localized enlargement of isopters). Behavioural improvements associated with a change in oscillatory activity within motion processing pathways were proportional to the amount of residual structural fibres along these pathways and perilesional primary visual cortex activity. In sum, we report, for the first time, that cf-tACS, a novel, pathway-specific, physiology-inspired brain stimulation approach, is able to boost the efficacy of perceptual training, restoring visual motion processing and reducing the severity of visual impairments in adult stroke patients.},

Although slow and labour intensive, evidence suggests that early interventions with tailored rehabilitation programmes might stimulate visual recovery and improve quality of life in stroke survivors.To enhance the effects of such rehabilitation programmes, we designed a novel, non-invasive, pathway-specific, physiology-inspired cross-frequency brain stimulation protocol, where complex oscillatory signal integration was inferred from phase\u2013amplitude coupling of oscillatory signals between the primary visual cortex and the motion-sensitive medio-temporal area. Sixteen stroke patients were enrolled in a double-blind, randomized, cross-over trial, during which they performed two blocks of 10 daily training sessions of a direction discrimination task, combined with one of the two cross-frequency transcranial alternative brain stimulation (cf-tACS versus control cf-tACS) conditions.We found that the cf-tACS condition promoting feedforward visual inputs to the medio-temporal area significantly enhanced motion discrimination performance and shifted visual field borders (i.e. through localized enlargement of isopters). Behavioural improvements associated with a change in oscillatory activity within motion processing pathways were proportional to the amount of residual structural fibres along these pathways and perilesional primary visual cortex activity. In sum, we report, for the first time, that cf-tACS, a novel, pathway-specific, physiology-inspired brain stimulation approach, is able to boost the efficacy of perceptual training, restoring visual motion processing and reducing the severity of visual impairments in adult stroke patients.<\/div>

However, it remains unclear whether such representations arise due to dynamic changes in choice-response associations or reflect a general property of decision-making. Here, we show that in the human brain, choices are represented abstractly even when choice-response associations remain stable over time. We recorded neural activity using magnetoencephalography while participants performed a motion discrimination task, with choice-response mappings held constant within blocks. We found neural information about participants' perceptual choices independent of both motor response and visual stimulus. Choice information increased during the stimulus and peaked after the response. Moreover, choice and response information showed distinct cortical distributions, with choice-related signals strongest in frontoparietal regions. Thus, abstract choice representations are not limited to dynamic or action-independent contexts and may be a general feature of decision-making.},

To address this issue, we leveraged multimodal learning analytics to collect eye movement (EM), electrodermal activity (EDA), heart rate (HR), and heart rate variability (HRV) from non-intrusive sensors and investigate whether they could predict the three types of cognitive load. We examined extraneous load (created by adding background music (BGM)), intrinsic load (created by text complexity), and germane load (reflected by comprehension accuracy) in a novel reading context with self-selected preferred BGM. One hundred and two (102) non-native English speakers were recruited. Half of them read English passages with BGM, while the other half read in silence. Results of logistic regression indicated that EM measures were predictive of the three load types, while HR\/HRV measures predicted extraneous and germane load. Our findings provide evidence supporting the triarchic structure of cognitive load theory and implications for the design of non-intrusive measurement of cognitive load.},

Here we report that when neural populations in macaque primary visual cortex are triggered to exhibit a periodic response to a repetitive sequence of optogenetic laser flashes, they learn to accurately reproduce the temporal sequence even when light stimulation is turned off. Despite the fact that individual cells had a poor capacity to extract temporal information, the population of neurons reproduced the periodic sequence in a temporally precise manner. The same neural population could learn different frequencies of external stimulation, and the ability to extract temporal information was found in all cortical layers. These results demonstrate a remarkable ability of sensory cortical populations to extract and reproduce complex temporal structure from unsupervised external stimulation even when stimuli are perceptually irrelevant.},

To do so, we engage participants in a collaborative task where they have to interact with another interlocutor (actually a bot) and inform each other about the location of landmarks on a map. In one condition the bot aligns with the participant and in the other it does not. Participants are recorded with an eye tracker during the experiment so that we can evaluate cognitive load and performance in the task. We found that when participants interact with an aligning bot, their cognitive load decreases and task completion is facilitated, but only to a certain degree. The results of the study suggest that alignment is a strategy that can be used in order to facilitate task performance.<\/p>},

This study examined whether pupil diameter before and during stimulus presentation predicts memory performance. We hypothesized that successfully recalled words would be associated with larger pupils than forgotten words, based on the role of arousal and attention in memory formation. To test these hypotheses, we conducted two experiments in which we tracked ninety-five psychology students' eyes while they performed a long-term memory test. The results depict larger pupil size while studying later successfully retrieved words. Interestingly, this phenomenon also occurs before word presentation (during baseline), which supports the \u201creadiness to remember\u201d (R2R) framework. This implies that pupillary changes while preparing to encode information can indicate later memory performance.},

We asked whether such confirmation biases result from biases in wthe encoding of sensory evidence in the brain, or alternatively in the utilization of encoded evidence for behavior. Human participants estimated the source of a sequence of visual-spatial evidence samples while we measured cortical population activity with magnetoencephalography. Halfway through the sequence, participants were prompted to judge the more likely source category. We find that processing of subsequent evidence depends on its consistency with the previously chosen category. Evidence encoded in parietal cortex contributes more to the estimation report when that evidence is consistent with the previous choice compared to when it contradicts that choice. Our results indicate that information contradicting pre-existing beliefs has little impact on subsequent behavior, despite being precisely encoded in the brain. This provides room for deliberative control to counteract confirmation biases.},
