Feeling the distance: The relationship between emotion regulation and spatial ability in childhood.

Research has shown experimentally that if children are taught to use language to create distance (socially, physically, and temporarily) when they revisit a potentially traumatic experience they reduce the intensity of their emotions. Building on this, this study was carried out to explore whether children with better spatial skills are better at such downregulation because of their very aptitude in understanding the concept of distance. Using data from a general-population birth cohort in the UK, the study examined the bidirectional association between emotional dysregulation and spatial ability among children aged 5 and 7 years. The findings reveal a significant reciprocal relationship even after adjusting for family, contextual, and individual confounders including verbal ability: spatial skills at age 5 years were inversely related to emotional dysregulation at age 7 years, and conversely, greater emotional dysregulation at age 5 years was associated with poorer spatial ability at age 7 years. The two paths were equally strong and there was no evidence of differences between them on the basis of sex. Our results suggest that enhancing spatial abilities could be a potential avenue for supporting emotion regulation in middle childhood.

Multiple Representations in geospatial databases, the brain's spatial cells, and deep learning algorithms.

Buttenfield (1988) pioneered research on multiple representations in the dawn of GIScience. Her efforts evoked inquiries into fundamental issues arising from the selective abstractions of infinite geographic complexity in spatial databases, cartography and application needs for varied geographic details. These fundamental issues posed ontological challenges (e.g., entity classification) and implementational complications (e.g., duplication and inconsistency) in geographic information systems (GIS). Expanding upon Buttenfield's line of research over the last three decades, this study reviewed multiple representations in spatial databases, spatial cognition, and deep learning. Initially perceived as a hindrance in GIS, multiple representations were found to offer new perspectives to encode and decipher geographic complexity. This paper commenced by acknowledging Buttenfield's pivotal contributions to multiple representations in GIScience. Subsequent discussions synthesized the literature to outline cognitive representations of space in the brain's hippocampal formation and feature representations in deep learning. By cross-referencing related concepts of multiple representations in GIScience, the brain's spatial cells, and machine learning algorithms, this review concluded that multiple representations facilitate learning geography for both humans and machines.

What Kind of Cognitive Technology Is the "Memory House"?

Ancient Roman "technical memory" is not (as much of the modern specialist literature would have it) a generative technology of association. Rather it is (as a literal reading of the texts would suggest) a specialized tool for precise serial recall. Modern experimental evidence both confirms the fitness for the purpose of the technique and shows why that purpose is not trivial, as some have suggested. While the mechanism(s) by which the technique operates are not fully understood, a review of the current literature suggests that it would have had the advantage over other mnemonic techniques by virtue of recruiting a variety of cognitive capacities. These likely include spatial/navigational mechanisms and possibly visual/imagery-based ones as well. Finally, small differences between the method as recorded in the ancient texts and similar methods that have been the subject of laboratory experiments are used to suggest possible directions for further experimentation.

Exploring neural efficiency in spatial cognition: A comparative study of 3D visual stimuli in virtual reality across STEM and non-STEM fields.

Spatial cognition plays a crucial role in our daily lives. The relationship between spatial abilities and mathematical performance is well-established, with visuospatial training offering significant benefits in academic STEM (Science, Technology, Engineering, and Mathematics) disciplines. Developing visuospatial training requires an objective evaluation of spatial cognition and consideration of various 3D displays. This study aims to compare the neural efficiency of STEM and non-STEM individuals during mental rotation tasks (MRT) in 3D and 2.5D conditions (pseudo 3D) using virtual reality (VR). For that, we propose a novel integrative assessment of spatial cognition by combining a cost-effective VR headset and functional near-infrared spectroscopy (fNIRS). Overall, the findings reveal that STEM individuals exhibit greater neural efficiency in the dorsolateral prefrontal cortex (PFC) while solving MRT in a VR environment compared to their non-STEM counterparts. Additionally, the study shows that there is no significant difference in performance between 3D and 2.5D stimuli, suggesting that both conditions are equally suitable for MRT in VR. One possible explanation is that immersive VR reduces the distinctions between 3D models and 2.5D images, considering MRT scores and PFC activity. This research underscores the practicality and relevance of using VR and fNIRS to evaluate visuospatial tasks and the potential to identify distinct student learning profiles and enhance spatial skills. Furthermore, it highlights the potential of 2.5D stimuli as a cost-effective alternative for learning applications in VR. Here, we demonstrated that modeling the same task in 3D and 2.5D conditions can compare how humans interact with visuospatial tests, providing insights into applying VR devices to develop spatial skills.

Methodological approach to investigating spatial cognition in Arctic charr (Salvelinus alpinus).

Assessing cognitive traits poses consistent methodological challenges. We describe a method for testing Arctic charr by incorporating a T-maze into their housing, which reduced stress and improved the engagement of the tested fish in the task. We outline the phases of testing to evaluate learning efficiency and determine which orientation strategies, such as motor response versus beaconing, are prioritized by the animals. We emphasize the stress management aspects of the design, aiming to inspire other researchers tackling similar obstacles, rather than delving into the specific aspects of cognitive abilities assessment.

Training of spatial cognitive abilities reduces symptoms of visually induced motion sickness.

Purpose: This study aims to explore the effectiveness of enhancing individual spatial cognitive abilities in alleviating the negative symptoms of visually induced motion sickness (VIMS). Additionally, it seeks to develop innovative intervention methods to improve spatial cognition and identify new treatment approaches for VIMS. Methods: The study investigated the impact of innovative interventions on spatial cognitive abilities and their modulation of VIMS susceptibility. A total of 43 participants were recruited (23 in the experimental group and 20 in the control group). The experimental group underwent six sessions of spatial cognitive ability training, while the control group engaged in activities unrelated to spatial cognition. Results: The analysis revealed that the spatial cognitive ability scores of the experimental group significantly improved after the intervention. Furthermore, the experimental group exhibited significant differences in nausea, oculomotor, disorientation, and total SSQ scores before and after the intervention, indicating that the intervention effectively mitigated VIMS symptoms. Conclusion: This study developed a virtual reality training method that effectively enhances individual spatial cognitive abilities and significantly alleviates VIMS symptoms, providing a novel and effective approach for VIMS intervention and treatment.

Minding the gap: a sex difference in young infants' mental rotation through thirty degrees of arc.

Mental rotation (MR) is an important feature of spatial cognition invoking mental imagery of an object's appearance when viewed from a new orientation. Prior studies have revealed evidence of MR in infants, including a sex difference similar to that detected in older populations. Some of these studies used visual habituation methods whereby infants were familiarized with an object rotating through a 240° angle, followed by test trials showing either the habituation object or a mirror image object rotating through the previously unseen 120° angle. Significantly longer looking at either of these objects was taken to reflect infants' ability to recognize the habituation object even when seen from a novel viewpoint, suggesting the capacity for MR. However, these infants' responses could, in theory, be explained with reference to perceptual discrimination rather than MR, because the views of the habituation and test objects were very similar in some video frames. In the current study, we observed a diverse population of 5-month-olds (24 females, 24 males) for evidence of MR through 30° of arc. In this more challenging test, our stimuli left a 30° gap angle between critical video frames representing the habituation and test objects. Consistent with earlier reports, we found that relative to female infants, male infants looked significantly longer at the mirror image test stimulus immediately following habituation. These results add to an emerging consensus that some young infants are capable of MR, and that male and female infants on average behave differently in this type of MR task.

On prior visual experience in mental map navigation using allocentric and egocentric perspectives in the visually impaired.

Using new developments in the mental comparison task paradigm, this study addresses the question of the influence of prior visual experience in the natural use of mental perspective to achieve mental spatial tasks without any protocol-imposed perspective. During the experiment, 39 participants (11 early blind, 13 late blind, and 15 blindfolded-sighted) explored two corridor maps to memorise the spatial arrangement of 10 objects disposed along corridors. After the learning phase, several tasks addressing spatial memory and reasoning used in the mental spatial representation were performed. Blindfolded-sighted participants preferred an egocentric perspective, while the two visually impaired groups showed no overriding preference between egocentric and allocentric perspectives. Results showed a performance advantage for egocentric over allocentric perspectives, regardless of visual experience. Our results shed light on previous assumptions regarding cognitive mental map construction, suggesting the need to reflect on previous results and their dependence on imposed mental perspectives.

The dorsal thalamic lateral geniculate nucleus is required for visual control of head direction cell firing direction in rats.

Head direction (HD) neurons, signalling facing direction, generate a signal that is primarily anchored to the outside world by visual inputs. We investigated the route for visual landmark information into the HD system in rats. There are two candidates: an evolutionarily older, larger subcortical retino-tectal pathway and a more recently evolved, smaller cortical retino-geniculo-striate pathway. We disrupted the cortical pathway by lesioning the dorsal lateral geniculate thalamic nuclei bilaterally, and recorded HD cells in the postsubicular cortex as rats foraged in a visual-cue-controlled enclosure. In lesioned rats we found the expected number of postsubicular HD cells. Although directional tuning curves were broader across a trial, this was attributable to the increased instability of otherwise normal-width tuning curves. Tuning curves were also poorly responsive to polarizing visual landmarks and did not distinguish cues based on their visual pattern. Thus, the retino-geniculo-striate pathway is not crucial for the generation of an underlying, tightly tuned directional signal but does provide the main route for vision-based anchoring of the signal to the outside world, even when visual cues are high in contrast and low in detail. KEY POINTS: Head direction (HD) cells indicate the facing direction of the head, using visual landmarks to distinguish directions. In rats, we investigated whether this visual information is routed through the thalamus to the visual cortex or arrives via the superior colliculus, which is a phylogenetically older and (in rodents) larger pathway. We lesioned the thalamic dorsal lateral geniculate nucleus (dLGN) in rats and recorded the responsiveness of cortical HD cells to visual cues. We found that cortical HD cells had normal tuning curves, but these were slightly more unstable during a trial. Most notably, HD cells in dLGN-lesioned animals showed little ability to distinguish highly distinct cues and none to distinguish more similar cues. These results suggest that directional processing of visual landmarks in mammals requires the geniculo-cortical pathway, which raises questions about when and how visual directional landmark processing appeared during evolution.

High-Pitched Sound is Open and Low-Pitched Sound is Closed: Representing the Spatial Meaning of Pitch Height.

Research shows that high- and low-pitch sounds can be associated with various meanings. For example, high-pitch sounds are associated with small concepts, whereas low-pitch sounds are associated with large concepts. This study presents three experiments revealing that high-pitch sounds are also associated with open concepts and opening hand actions, while low-pitch sounds are associated with closed concepts and closing hand actions. In Experiment 1, this sound-meaning correspondence effect was shown using the two-alternative forced-choice task, while Experiments 2 and 3 used reaction time tasks to show this interaction. In Experiment 2, high-pitch vocalizations were found to facilitate opening hand gestures, and low-pitch vocalizations were found to facilitate closing hand gestures, when performed simultaneously. In Experiment 3, high-pitched vocalizations were produced particularly rapidly when the visual target stimulus presented an open object, and low-pitched vocalizations were produced particularly rapidly when the target presented a closed object. These findings are discussed concerning the meaning of intonational cues. They are suggested to be based on cross-modally representing conceptual spatial knowledge in sensory, motor, and affective systems. Additionally, this pitch-opening effect might share cognitive processes with other pitch-meaning effects.

Individual differences in spatial working memory strategies differentially reflected in the engagement of control and default brain networks.

Spatial locations can be encoded and maintained in working memory using different representations and strategies. Fine-grained representations provide detailed stimulus information, but are cognitively demanding and prone to inexactness. The uncertainty in fine-grained representations can be compensated by the use of coarse, but robust categorical representations. In this study, we employed an individual differences approach to identify brain activity correlates of the use of fine-grained and categorical representations in spatial working memory. We combined data from six functional magnetic resonance imaging studies, resulting in a sample of $155$ ($77$ women, $25 \pm 5$ years) healthy participants performing a spatial working memory task. Our results showed that individual differences in the use of spatial representations in working memory were associated with distinct patterns of brain activity. Higher precision of fine-grained representations was related to greater engagement of attentional and control brain systems throughout the task trial, and the stronger deactivation of the default network at the time of stimulus encoding. In contrast, the use of categorical representations was associated with lower default network activity during encoding and higher frontoparietal network activation during maintenance. These results may indicate a greater need for attentional resources and protection against interference for fine-grained compared with categorical representations.

Visual perspective taking and action understanding.

Understanding what others are doing is a fundamental aspect of social cognition and a skill that is arguably linked to visuospatial perspective taking (VPT), the ability to apprehend the spatial layout of a scene from another's perspective. Yet, with few and notable exceptions, action understanding and VPT are rarely studied together. Participants (43 females, 37 males) made judgements about the spatial layout of objects in a scene from the perspective of an avatar who was positioned at 0°, 90°, 270° or 180° relative to the participant. In a variant of a traditional VPT task, the avatar either interacted with the objects in the scene, by pointing to or reaching for them, or was present but did not engage with the objects. Although the task was identical across all conditions - to say whether a target object is to the right or left of a control object - we show that the avatar's actions modulates performance. Specifically, participants were more accurate when the avatar engaged with the target object, and correspondingly, less accurate and slower when the avatar interacted with the control objects. As these effects were independent of the angular disparity between participant and avatar perspectives, we conclude that action understanding and VPT are likely linked via the rapid deployment of two separate cognitive mechanisms. All participants provided a measure of self-reported empathy and we show that response times decrease with increasing empathy scores for female but not for male participants. However, within the range of 'typical' empathy scores, defined here as the interquartile range where 50 % of the data lie, females were faster than males. These findings lend further insight into the relationship between spatial and social perspective taking.

Are spatial terms rooted in geometry or force-dynamics? Yes.

Theories of spatial term meanings often focus on geometric properties of objects and locations as the key to understanding meaning. For example, in English, "The cat is on the mat" might engage geometric properties characterizing the figure ('cat', a point) and the ground ('mat', a plane) as well as the geometric relationship between the two objects ('on', + vertical, 0 distance from ground object). However, substantial literature suggests that geometric properties are far from sufficient to capture the meanings of many spatial expressions, and that instead, force-dynamic properties of objects that afford containment or support relationships may be crucial to the meanings of those expressions. I will argue that both approaches are needed to understand the variety of spatial terms that appear in language and further, that spatial terms fall into two distinct sets, one represented by geometric properties of figure and ground and their spatial relationships, and the other by the force-dynamic properties of objects and their relationships. This division of labor within spatial terms has many consequences, with the two types differing in the nature of the acquisition problem and likely learning mechanisms, the extent and kind of cross-linguistic variation that has been observed, and the application of pragmatic principles to spatial terms. Speculatively, the two types may also be rooted in different cognitive systems and their neural substrates.

Spatial attention in three-dimensional space: A meta-analysis for the near advantage in target detection and localization.

Studies have explored how human spatial attention appears allocated in three-dimensional (3D) space. It has been demonstrated that target distance from the viewer can modulate performance in target detection and localization tasks: reaction times are shorter when targets appear nearer to the observer compared to farther distances (i.e., near advantage). Times have reached to quantitatively analyze this literature. In the current meta-analysis, 29 studies (n = 1260 participants) examined target detection and localization across 3-D space. Moderator analyses included: detection vs localization tasks, spatial cueing vs uncued tasks, control of retinal size across depth, central vs peripheral targets, real-space vs stereoscopic vs monocular depth environments, and inclusion of in-trial motion. The analyses revealed a near advantage for spatial attention that was affected by the moderating variables of controlling for retinal size across depth, the use of spatial cueing tasks, and the inclusion of in-trial motion. Overall, these results provide an up-to-date quantification of the effect of depth and provide insight into methodological differences in evaluating spatial attention.

Size adaptation: Do you know it when you see it?

The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon.

Virtual, mixed, and augmented realities: A commentary on their significance in cognitive neuroscience and neuropsychology.

The integration of virtual, mixed, and augmented reality technologies in cognitive neuroscience and neuropsychology represents a transformative frontier. In this Commentary, we conducted a meta-analysis of studies that explored the impact of Virtual Reality (VR), Mixed Reality (MR), and Augmented Reality (AR) on cognitive neuroscience and neuropsychology. Our review highlights the versatile applications of VR, ranging from spatial cognition assessments to rehabilitation for Traumatic Brain Injury. We found that MR and AR offer innovative avenues for cognitive training, particularly in memory-related disorders. The applications extend to addressing social cognition disorders and serving as therapeutic interventions for mental health issues. Collaborative efforts between neuroscientists and technology developers are crucial, with reinforcement learning and neuroimaging studies enhancing the potential for improved outcomes. Ethical considerations, including informed consent, privacy, and accessibility, demand careful attention. Our review identified common aspects of the meta-analysis, including the potential of VR technologies in cognitive neuroscience and neuropsychology, the use of MR and AR in memory research, and the role of VR in neurorehabilitation and therapy.

Overturning Children's Misconceptions about Ruler Measurement: The Power of Disconfirming Evidence.

Children have persistent difficulty with foundational measurement concepts, which may be linked to the instruction they receive. Here, we focus on testing various ways to support their understanding that rulers comprise spatial interval units. We examined whether evidence-based learning tools-disconfirming evidence and/or structural alignment-enhance their understanding of ruler units. Disconfirming evidence, in this context, involves having children count the spatial interval units under an object that is not aligned with the origin of a ruler. Structural alignment, in this context, involves highlighting what a ruler unit is by overlaying plastic unit chips on top of ruler units when an object is aligned with the origin of a ruler. In three experiments employing a pre-test/training/post-test design, a total of 120 second graders were randomly assigned to one of six training conditions (two training conditions per experiment). The training conditions included different evidence-based learning principles or "business-as-usual" instruction (control), with equal allocation to each (N = 20 for each condition). In each experiment, children who did not perform above chance level on the pre-test were selected to continue with training, which resulted in a total of 88 students for the analysis of improvement. The children showed significant improvement in training conditions that included disconfirming evidence, but not in the structural alignment or control conditions. However, an exploratory analysis suggests that improvement occurred more rapidly and was retained better when structural alignment was combined with disconfirming evidence compared to disconfirming evidence alone.

Embodied Spatial Navigation Training in Mild Cognitive Impairment: A Proof-of-Concept Trial.

Background: Egocentric and allocentric spatial memory impairments affect the navigation abilities of older adults with mild cognitive impairment (MCI). Embodied cognition research hints that specific aids can be implemented into virtual reality (VR) training to enhance spatial memory. Objective: In this study, we preliminarily tested 'ANTaging', an embodied-based immersive VR training for egocentric and allocentric memory, compared to treatment as usual (TAU) spatial training in MCI. Methods: MCI patients were recruited for this controlled trial. A cognitive battery was administered at pre-test, after ten sessions of ANTaging or TAU intervention, and at 3-month follow-up (FU). The primary outcomes were spatial cognition tests (Corsi supra-span, CSS; Manikin test, MT). VR egocentric and allocentric performance was also collected. Results: We found that ANTaging significantly improved MT scores at FU compared to TAU. CSS slightly improved in both groups. Concerning secondary outcomes, auditory-verbal forgetting significantly improved at post-test in the ANTaging but not TAU group and significantly declined at FU in the TAU but not in the ANTaging group. Global cognition significantly improved at FU for TAU and remained stable for ANTaging. Other tests showed no improvement or deterioration. Clinical significance showed that ANTaging is effective for CSS. Virtual egocentric and allocentric memory performance improved across ANTaging sessions. Conclusions: ANTaging holds the potential to be superior for improving spatial cognition in MCI compared to TAU. Embodied cognition research provides insights for designing effective spatial navigation rehabilitation in aging.

Causal computations of supplementary motor area on spatial impulsivity.

Spatial proximity to important stimuli often induces impulsive behaviour. How we overcome impulsive tendencies is what determines behaviour to be adaptive. Here, we used virtual reality to investigate whether the spatial proximity of stimuli is causally related to the supplementary motor area (SMA) functions. In two experiments, we set out to investigate these processes using a virtual environment that recreates close and distant spaces to test the causal contributions of the SMA in spatial impulsivity. In an online first experiment (N = 93) we validated and measured the influence of distant stimuli using a go/no-go task with close (21 cm) or distant stimuli (360 cm). In experiment 2 (N = 28), we applied transcranial static magnetic stimulation (tSMS) over the SMA (double-blind, crossover, sham-controlled design) to test its computations in controlling impulsive tendencies towards close vs distant stimuli. Reaction times and error rates (omission and commission) were analysed. In addition, the EZ Model parameters (a, v, Ter and MDT) were computed. Close stimuli elicited faster responses compared to distant stimuli but also exhibited higher error rates, specifically in commission errors (experiment 1). Real stimulation over SMA slowed response latencies (experiment 2), an effect mediated by an increase in decision thresholds (a). Current findings suggest that impulsivity might be modulated by spatial proximity, resulting in accelerated actions that may lead to an increase of inaccurate responses to nearby objects. Our study also provides a first starting point on the role of the SMA in regulating spatial impulsivity.
