Isolating delayed attentional disengagement from biased orienting to signals of threat in anxiety – not there yet

ABSTRACT It is often argued that increased “attentional bias to threat” in anxiety is due to delayed attentional disengagement from threat stimuli, rather than increased attentional orienting towards such signals. In 2013, [Clarke, P. J. F., Macleod, C., & Guastella, A. J. (2013). Assessing the role of spatial engagement and disengagement of attention in anxiety-linked attentional bias: A critique of current paradigms and suggestions for future research directions. Anxiety, Stress and Coping: An International Journal, 26(1), 1-19. https://doi.org/10.1080/10615806.2011.638054] critiqued this literature, pointing out that most studies used paradigms that could not isolate attentional disengagement from attentional orienting. Since this critique, over fifty studies claiming to measure attentional disengagement from threat in anxiety have been published, many using suboptimal methods. In this (preregistered) systematic review and meta-analysis, we outline why many of these paradigms fail to provide a valid measure of attentional disengagement from stimuli with different emotional content. We also highlight studies where the paradigms and task parameters allowed for the valid measurement of attentional disengagement and include a meta-analysis (759 participants) of this subset. Some evidence was observed for slowed disengagement from threat images (relative to neutral) in high-anxious individuals, but heterogeneity across studies was high, and the effect disappeared when restricting the analysis to paradigms that could rule out behavioural freezing as an alternative explanation. Overall, these findings highlight the need for better-quality research in this area and suggest best practices for the field moving forward.

Foraging and inertia: Understanding the developmental dynamics of overt visual attention.

During early life, we develop the ability to choose what we focus on and what we ignore, allowing us to regulate perception and action in complex environments. But how does this change influence how we spontaneously allocate attention to real-world objects during free behaviour? Here, in this narrative review, we examine this question by considering the time dynamics of spontaneous overt visual attention, and how these develop through early life. Even in early childhood, visual attention shifts occur both periodically and aperiodically. These reorientations become more internally controlled as development progresses. Increasingly with age, attention states also develop self-sustaining attractor dynamics, known as attention inertia, in which the longer an attention episode lasts, the more the likelihood increases of its continuing. These self-sustaining dynamics are driven by amplificatory interactions between engagement, comprehension, and distractibility. We consider why experimental measures show decline in sustained attention over time, while real-world visual attention often demonstrates the opposite pattern. Finally, we discuss multi-stable attention states, where both hypo-arousal (mind-wandering) and hyper-arousal (fragmentary attention) may also show self-sustaining attractor dynamics driven by moment-by-moment amplificatory child-environment interactions; and we consider possible applications of this work, and future directions.

Priming using human and chimpanzee expressions of emotion biases attention toward positive emotions

ABSTRACT Perceiving and correctly interpreting emotional expressions is one of the most important abilities for social animals’ communication. It determines the majority of social interactions, group dynamics, and cooperation – being highly relevant for an individual’s survival. Core mechanisms of this ability have been hypothesised to be shared across closely related species with phylogenetic similarities. This study explored homologies in human processing of species-specific facial expressions using eye-tracking. Introducing a prime-target paradigm, we tested the influences on human attention elicited by priming with differently valenced emotional stimuli depicting human and chimpanzee faces. We demonstrated an attention shift towards the conspecific (human) target picture that was congruent with the valence depicted in the primer picture. We did not find this effect with heterospecific (chimpanzee) primers and ruled out that this was due to participants interpreting them incorrectly. Implications about the involvement of related emotion-processing mechanisms for human and chimpanzee facial expressions are discussed. Systematic cross-species-investigations of emotional expressions are needed to unravel how emotion representation mechanisms can extend to process other species’ faces. Through such studies, we can better understand the implications of humans’ and apes’ shared evolutionary ancestry and better understand “Where our emotions come from”.

Electrophysiological signatures of the effect of context on exploration: Greater attentional and learning signals when exploration is costly.

Humans are excellent at modifying our behaviour depending on context. For example, humans will change how they explore when losses are possible compared to when they are not possible. However, it remains unclear what specific cognitive and neural processes are modulated when exploring in different contexts. Here, we had participants learn within two different contexts: in one the participants could lose points while in the other the participants could not. Our goal was to determine how the inclusion of losses impacted human exploratory behaviour (experiment one), and whether we could explain the neural basis of these effects using EEG (experiment two). In experiment one, we found that participants preferred less-variable choices and explored less often when losses were possible. In addition, computational modelling revealed that participants engaged in less random exploration, had a lower rate of learning, and showed less choice perseverance when losses were possible. In experiment two, we replicated these effects while examining a series of neural signals involved in exploration. During exploration, signals tied to working memory and learning (P3b), attention orienting (P3a) and motivation (late positive potential; an exploratory analysis) were also enhanced when losses were possible. These neural differences contribute to why exploratory behaviour is changed by different learning contexts and can be explained by the theoretical claim that losses recruit attention and lead to increased task focus. These results provide insight into the cognitive processes that underlie exploration, and how exploratory behaviour changes across contexts.

The effect of infra low frequency-neurofeedback training on pistol shooting performance and attention in semi-skilled players.

Neurofeedback (NF) typically involves an operant conditioning or other reinforcement protocol aimed at self-regulating patterns of brain activation. Endogenous Neuromodulation, characterized by the absence of discrete reinforcers, has emerged over the last two decades with the extension of training into the infra-low frequency regime, i.e., below 0.1 Hz. Specifically, Infra-Low Frequency (ILF) Neurofeedback training has demonstrated efficacy in enhancing the self-organization and regulation of the central nervous system in considerable generality. The present study explores a pivotal question: Can Infra-Low Frequency (ILF) Neurofeedback, acknowledged for its influence on arousal, vigilance, and emotional states, effectively enhance both attention generally and shooting performance specifically? Additionally, we explored whether the training exerted beneficial effects on three attentional networks-Conflict, Orienting, and Alerting. To assess shooting performance, we employed the Shooter's Coordination Analysis Target Training (SCATT), while attention networks were gauged through the Attention Network Test (ANT). Twenty semi-skilled pistol shooters, aged 28-40, underwent both the ANT and SCATT assessments before and after completing 20 half-hour ILF-Neurofeedback sessions. The participants were randomly assigned to two groups: an ILF NFB group, which underwent 20 sessions of ILF NFB training, and a control group that received no NFB. Our findings revealed that ILF-Neurofeedback significantly enhanced performance. In the ANT, the training led to a reduction in Conflict and an increase in Orienting and Alerting. The study demonstrates the effectiveness of ILF-Neurofeedback in improving shooting performance, and in positively impacting all three attention networks assessed by the ANT.

Mixed Attention and Channel Shift Transformer for Efficient Action Recognition

Mixed Attention and Channel Shift Transformer for Efficient Action Recognition

Resonance+: Operationalizing Protective Action Decision Model for Finding Information Useful for Public Information Officers

Microblogging platforms have been increasingly used by the public in crisis situations, enabling more participatory crisis communication between the official response channels and the affected community. However, the sheer volume of crisis-related messages on social media can make it challenging for officials to find pertinent information and understand the public’s perception of evolving risks. To address this issue, crisis informatics researchers have proposed a variety of technological solutions, but there has been limited examination of the cognitive and perceptual processes and subsequent responses of the affected population. Yet, this information is critical for the crisis response officials to gauge public’s understanding of the event, their perception of event-related risk, and perception of incident response and recovery efforts, in turn enabling the officials to craft crisis communication messaging more effectively. Taking cues from the Protective Action Decision Model, we conceptualize a metric —resonance+ — that prioritizes the cognitive and perceptual processes of the affected population, quantifying shifts in collective attention and information exposure for each tweet. Based on resonance+, we develop a principled, scalable pipeline that recommends content relating to people’s cognitive and perceptual processes. Our results suggest that resonance+ is generalizable across different types of natural hazards. We have also demonstrated its applicability for near-real time scenarios. According to the feedback from the target users, the local public information officers (PIOs) in emergency management, the messages recommended by our pipeline are useful in their tasks of understanding public perception and finding hopeful narratives, potentially leading to more effective crisis communications.

Eye movements follow the dynamic shifts of attention through serial order in verbal working memory

How are arbitrary sequences of verbal information retained and manipulated in working memory? 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.

Cosmic Flow and Human Action: Philosophical Intersections between the Yijing and Whitehead’s Process Cosmology

Abstract This article explores the philosophical framework underpinning the Yijing (Book of Changes) and its resonance with the thought of Arthur North Whitehead, whose process cosmology has been well received within scholarship on Chinese philosophy. It examines sinologists’ interpretations of the Yijing through the lens of Whitehead’s process cosmology, highlighting key similarities in their metaphysical view of reality as dynamic and interwoven. However, while Whitehead’s philosophy, like other Western frameworks such as modern physics, focuses on understanding the fundamental “stuff” of the universe, the Yijing’s cosmology of change shifts attention to human action within this unpredictable world. Through analysis of the Xici zhuan commentary, the article investigates the role of symbolic representation, divination, and moral choice in the Yijing’s guidance on how one perceives, lives, and acts within this ever-unfolding universe, thereby encompassing not just cosmology but also epistemology and ethics.

Flood Photography and the Visual Component of Environmental American Studies

This article develops a new approach for using photographic sources that might be of interest to American Studies scholars whose research contributes broadly to environmental education. Over the past forty years of photographic scholarship, scientific and other record images have become relatively prominent as primary sources. This visual material can be used to interrogate past responses to flooding and other environmental events. On the other hand, discourses around social documentary continue to frame how the human impacts of rapidly changing environments are visualised. By comparing two sets of images from the 1930s, the article juxtaposes the approaches of photographers associated with these two conventionally distinct areas to offer a more rounded view of flood photography. The discussion starts with a reflective section detailing how I arrived at my current research project. Following this, the categories of scientific and social documentary photography are described relationally in the context of the agencies of the New Deal, in the process setting out an argument for the contribution that engaged visuality can make to Environmental American Studies. Afterwards, the attention shifts to focus on images from two official contexts. The first example concerns record photography from the Soil Conservation Experiment Station in Bethany, Missouri, whilst the second considers photographs that the Resettlement Administration produced in response to flooding in Posey County, Indiana, in 1937. The article concludes by remarking on some of the implications of this method for how American Studies researchers currently conduct environmentally focused projects.

Alchornea cordifolia leaf-extract ameliorates bisphenol A-induced obesity in male Wistar rats

BackgroundBisphenol-A (BPA), a chemical impregnated into plastic bottles which has been linked to obesity and its associated health problems, was used to induce obesity in this study. The cost and reported limitations and side effects of orthodox medications employed for weight management, have necessitated a shift in attention to medicinal plants, given their comparative advantage and the common belief amongst locals that plants are free from negative side effects. One plant that has found application for weight loss amongst the local population in Nigeria is Alchornea cordifolia which commonly grows in Africa and has been confirmed to possess numerous medicinal properties including anti-inflammatory, anti-diarrheal, hepaprotective, antiviral, and anti-diabetic effects.ObjectiveTo evaluate the obesity attenuation effect of Alchornea cordifolia ethanol extract (ACEE) and other associated macrovascular health risks in BPA-induced obesity rat model.MethodsThirty (30) young male Wistar rats (80–100 g) divided into five groups of six rats each, were administered BPA (50 mg/kg), once a day, p.o. for four weeks in order to induce obesity. Afterwards, obesity was confirmed using anthropometric indicators, and the animals were treated for another four weeks as follows: Group 1 (Normal control) received drug/extract reconstitution solvent, olive oil, Group 2 (obese control) received 50 mg/kg of BPA, Group 3 received a conventional anti-obesity drug, Orlistat (30 mg/kg), Group 4 received ACEE (500 mg/kg), and Group 5 received ACEE (1000 mg/kg). At the end of study, anthropometric indicators and relevant serum biochemical indicators were determined using standard procedures.ResultsThe results obtained showed that oral BPA administration caused obesity i.e. increased body weight, Lee’s Index and waist circumference, compared to the normal control (p < 0.05). Moreover, BPA treatment was found to alter measured serum biochemical indicators, (FBG, lipid profile, liver and kidney function indicators) and the lipid regulating enzymes (pancreatic lipase and HMG-CoA reductase activities), relative to the normal control (p < 0.05). However, upon 4-week ACEE oral treatment at 500 and 1000 mg/kg b.w., there was observed significant attenuation of the anthropometric indices, serum biochemical indices and lipid metabolizing enzymes studied (p < 0.05).ConclusionTogether, the results obtained from this study have scientifically validated the traditional use of Alchornea cordifolia leaves in body weight control, hence suggest that the leaves may possess natural products useful in the management of obesity and its related complications.

Preparatory Switches of Auditory Spatial and Non-Spatial Attention Among Simultaneous Voices.

Can one shift attention among voices at a cocktail party during a silent pause? Researchers have required participants to attend to one of two simultaneous voices - cued by its gender or location. Switching the target gender or location has resulted in a performance 'switch cost' - which was recently shown to reduce with preparation when a gender cue was presented in advance. The current study asks if preparation for a switch is also effective when a voice is selected by location. We displayed a word or image 50/800/1400 ms before the onset of two simultaneous dichotic (male and female) voices to indicate whether participants should classify as odd/even the number spoken by the voice on the left or on the right; in another condition, we used gender cues. Preparation reduced the switch cost in both spatial-and gender-cueing conditions. Performance was better when each voice was heard on the same side as on the preceding trial, suggesting 'binding' of non-spatial and spatial voice features - but this did not materially influence the reduction in switch cost with preparation, indicating that preparatory attentional shifts can be effective within a single (task-relevant) dimension. We also asked whether words or pictures are more effective for cueing a voice. Picture cues resulted in better performance than word cues, especially when the interval between the cue and the stimulus was short, suggesting that (presumably phonological) processes involved in the recognition of the word cue interfered with the (near) concurrent encoding of the target voice's speech.

Beyond de Patient: A Lesson in Vigilance and Care.

A neurology resident reflects on a pivotal moment during the assessment of an elderly patient, when attention shifts unexpectedly to the patient's caregiver, his wife. The resident quickly recognizes a neurological deficit that could potentially be treated. Sensing the urgency, the resident rushes her to the emergency department, where immediate treatment enables the caregiver to regain her ability to continue caring for her husband. This experience teaches the resident a profound lesson about the importance of vigilance not only toward primary patients but also toward those quietly supporting them. It highlights how timely intervention can preserve the connections that bind families, emphasizing the role of healthcare providers in maintaining these bonds.

The shift of attention: Salience modulates the local vs global processing of auditory scenes in musicians and non-musicians.

This study addresses how salience shapes the perceptual organization of an auditory scene. A psychophysical task that was introduced previously by Susini, Jiaouan, Brunet, Houix, and Ponsot [(2020). Sci. Rep. 10(1), 16390] was adapted to assess how the ability of non-musicians and expert musicians to detect local/global contour changes in simple hierarchically-organized tone sequences is affected by the relative salience of local information in the timbre dimension. Overall, results show that salience enhanced local processing capacities, at the cost of global processing, suggesting a bottom-up reallocation of attention. Interestingly, for non-musicians, salience caused a reversal of the basic global-over-local processing prioritization as it is typically observed in expert musicians.

On the interaction between implicit statistical learning and the alternation advantage: Evidence from manual and oculomotor serial reaction time tasks.

In this study, we examine how implicit statistical learning (ISL) interacts with the cognitive bias of the alternation advantage in serial reaction time (SRT) tasks. Our aim was to disentangle perceptual from motor aspects of learning, as well as to shed light on the cognitive sources of this alternation effect. We developed a manual (Study 1) and an oculomotor (Study 2) two-choice SRT task, with visual stimuli following the regularities of two binary artificial grammars (Fibonacci and its modification Skip). While these grammars share some deterministic transitional regularities, they differ in their probabilistic transitional regularities and distributional properties. The pattern of manual RTs in Study 1 provide evidence for ISL, showing that subjects learned the deterministic and probabilistic transitions in the two grammars. We also found a bias toward alternation (vs. repetition) in correspondence to non-deterministic points, regardless of their statistical properties in the grammars. Study 2 provides further evidence for both ISL and the alternation advantage, in terms of shorter manual RTs and higher accuracy rates of anticipatory eye movements. Saccadic responses preceding stimulus onset allow us to argue for the perceptual nature of ISL: participants detected regularities in the string by forming S-S associations based on the sequence of the perceived stimuli. Moreover, we propose that shifts in visuospatial attention preceding oculomotor programming play a role in the occurrence of the alternation advantage, and that such an effect is driven by the spatial location of the stimulus. These findings are also discussed with respect to the presence of two (possibly interacting) parsing strategies: statistical generalizations on the string vs. local hierarchical reconstruction.

Is Overlain Display a Right Choice for AR Navigation? A Qualitative Study of Head-Mounted Augmented Reality Surgical Navigation on Accuracy for Large-Scale Clinical Deployment.

During the course of the past two decades, head-mounted augmented reality surgical navigation (HMARSN) systems have been increasingly employed in a variety of surgical specialties as a result of both advancements in augmented reality-related technologies and surgeons' desires to overcome some drawbacks inherent to conventional surgical navigation systems. In the present time, most experimental HMARSN systems adopt overlain display (OD) that overlay virtual models and planned routes of surgical tools on corresponding physical tissues, organs, lesions, and so forth, in a surgical field so as to provide surgeons with an intuitive and direct view to gain better hand-eye coordination as well as avoid attention shift and loss of sight (LOS), among other benefits during procedures. Yet, its system accuracy, which is the most crucial performance indicator of any surgical navigation system, is difficult to ascertain because it is highly subjective and user-dependent. Therefore, the aim of this study was to review presently available experimental OD HMARSN systems qualitatively, explore how their system accuracy is affected by overlain display, and find out if such systems are suited to large-scale clinical deployment. We searched PubMed and ScienceDirect with the following terms: head mounted augmented reality surgical navigation, and 445 records were returned in total. After screening and eligibility assessment, 60 papers were finally analyzed. Specifically, we focused on how their accuracies were defined and measured, as well as whether such accuracies are stable in clinical practice and competitive with corresponding commercially available systems. The primary findings are that the system accuracy of OD HMARSN systems is seriously affected by a transformation between the spaces of the user's eyes and the surgical field, because measurement of the transformation is heavily individualized and user-dependent. Additionally, the transformation itself is potentially subject to changes during surgical procedures, and hence unstable. Therefore, OD HMARSN systems are not suitable for large-scale clinical deployment.

Attentional modulation of peripheral pointing hypometria in healthy participants: an insight into optic ataxia?

Damage to the superior parietal lobule and intraparietal sulcus (SPL-IPS) causes optic ataxia (OA), characterized by pathological gaze-centered hypometric pointing to targets in the affected peripheral visual field. The SPL-IPS is also involved in covert attention. Here, we investigated the possible link between attention and action. This study investigated the effect of attention on pointing performance in healthy participants and two OA patients. In invalid trials, targets appeared unpredictably across different visual fields and eccentricities. Valid trials involved cued targets at specific locations. The first experiment used a central cue with 75% validity, the second used a peripheral cue with 50% validity. The effect of attention on pointing variability (noise) or time was expected as a confirmation of cueing efficiency. Critically, if OA reflects an attentional deficit, then healthy participants, in the invalid condition (without attention), were expected to produce the gaze-centered hypometric pointing bias characteristic of OA. RESULTS: revealed main effects of validity on pointing biases in all participants with central predictive cueing, but not with peripheral low predictive cueing. This suggests that the typical underestimation of visual eccentricity in OA (visual field effect) at least partially results from impaired endogenous attention orientation toward the affected visual field.

Predicting the Irrelevant: Neural Effects of Distractor Predictability Depend on Load.

Distraction is ubiquitous in human environments. Distracting input is often predictable, but we do not understand when or how humans can exploit this predictability. Here, we ask whether predictable distractors are able to reduce uncertainty in updating the internal predictive model. We show that utilising a predictable distractor identity is not fully automatic but in part depends on available resources. In an auditory spatial n-back task, listeners (n = 33) attended to spoken numbers presented to one ear and detected repeating items. Distracting numbers presented to the other ear either followed a predictable (i.e., repetitive) sequence or were unpredictable. We used electroencephalography (EEG) to uncover neural responses to predictable versus unpredictable auditory distractors, as well as their dependence on perceptual and cognitive load. Neurally, pairs of targets and unpredictable distractors induced a sign-reversed lateralisation of pre-stimulus alpha oscillations (~10 Hz) and larger amplitude of the stimulus-evoked P2 event-related potential component. Under low versus high memory load, distractor predictability increased the magnitude of the frontal negativity component. Behaviourally, predictable distractors under low task demands (i.e., good signal-to-noise ratio and low memory load) made participants adopt a less biased response strategy. We conclude that predictable distractors decrease uncertainty and reduce the need for updating the internal predictive model. In turn, unpredictable distractors might mislead proactive spatial attention orientation, elicit larger neural responses and put higher demand on memory.

An Analysis on Research Trends in Rural Spaces using Text Mining

Background and objective: As the significance and function of rural areas change, the value of rural space has become increasingly recognized in modern society. Consequently, while the concept of rural space has developed over time and led to modifications in relevant policies, there are insufficient studies that focus on these changes based on a broad definition of rural space. Therefore, the aim of this study is to analyze trends in rural space research over time by applying text mining to academic papers on the topic of domestic rural space.Methods: First, for data collection, the search keyword was set as 'rural space' in the Korea Citation Index (KCI), and 1,581 academic papers from 2003 to 2024 were collected. After removing inappropriate ones, a total of 473 articles were selected. The analysis was conducted by dividing the data into five periods. Following that, preprocessing and word frequency, TF-IDF, and LDA topic modeling analysis were performed through Textom, a big data analytics platform.Results: The analysis revealed several key trends over the five periods. First, the volume of research on rural space has increased over time, indicating a growing interest in this field. Second, shifts in the paradigm of rural space research were observed through changes in keywords, reflecting evolving research priorities. Third, it was discovered that rural space research is gradually developing into a comprehensive approach and expanding into empirical research. This expansion is characterized by three themes extracted from each period: 'village-level development,' 'landscape and environment,' and 'service development and value creation'.Conclusion: The findings showed an increasing focus on preserving 'ruralness', which is a unique feature of rural space, as attention shifts toward landscape preservation, ecology, and the environment. This trend aligns with the expectations and values for rural space, as well as social demands that value sustainable development, indicating the potential for further research expansion and revitalization.

Postmaterialism in Innovation and Religious Faith

ObjectivesThe postmaterialist paradigm in science is reflected in innovation research. It implies a shift of attention towards the intangible needs of people and the goals of sustainable development, rather than profit and economic growth as the goals of innovation. It reflects Catholic social teaching with its emphasis on social and environmental issues. In the article I explore if the Christian religion is conducive to post-materialist attitudes, and if post-materialism is more prevalent among people more involved in innovative activities in the workplace and in more innovative countries.Material and methodsWorlds Value Survey and OECD data were analyzed to explore the relationship between postmaterialism, religious belief, and innovation. The methods used were contingency tables and tests of significance for differences in proportions, and logit modelsResultsThe results show that Christian religion is associated with postmaterialist attitudes and work connected with innovation processes. However, postmaterialism also appears to replace religion for atheists, which reflects the human need for spirituality and ethics.ConclusionsThe results show that there is a social background in more developed countries to the transformation toward a postmaterialist innovation ecosystem, including not only business innovation, but also non-profit innovation. Postmaterialist innovation aims not only for individual material well-being, but also for a higher quality of life for entire societies. It is also in line with Catholic social teaching.
