Action observation reveals a network with divergent temporal and parietal cortex engagement in dogs compared with humans

Abstract Action observation is a fundamental pillar of social cognition. Neuroimaging research has revealed a human and non-human primate action observation network (AON) encompassing frontotemporoparietal areas with links to the species’ imitation tendencies and relative lobe expansion. Dogs (Canis familiaris) have good action perception and imitation skills and a less expanded parietal than temporal cortex, but their AON remains unexplored. We conducted a functional MRI study with 28 dogs and 40 humans and found functionally analogous involvement of somatosensory and temporal brain areas of both species’ AONs and responses to transitive and intransitive action observation in line with their imitative skills. Employing a functional localizer, we also identified functionally analogous agent-responsive areas within both species’ AONs. However, activation and task-based functional connectivity measures suggested significantly less parietal cortex involvement in dogs than in humans. These findings advance our understanding of the neural bases of action understanding and the convergent evolution of social cognition, with analogies and differences resulting from similar social environments and divergent brain expansion, respectively.

Frontal Cortex Acts as Causality Transition Hub from Mirror Network to Mentalizing Network During Action Intention Understanding.

Introduction: While understanding other's action intention, mirror and mentalizing systems of human brain are successively activated in action perception and intention inference processes. Methods: To reveal the relationship between mirror and mentalizing systems during the two stages, this electroencephalogram study adopted the method of time-varying orthogonalized partial directed coherence (OPDC) to assess causal interaction between mirror and mentalizing networks during a "hand-cup interaction" action intention understanding task. Results: Task-related causal connectivity was found in gamma frequency band (30-45 Hz), primarily manifested as directed edges from sensorimotor to frontal areas in poststimulus 400-600 ms interval and directed links from frontal to parietal and temporal regions in 600-800 ms period. The analysis of event-related potential and source currents suggests that the change of inter-regional causality is related with functional transition of the brain from mirror matching to intention inference. The OPDC network modeling further finds that frontal area contains more inflow nodes in mirror network, whereas more outflow nodes in mentalizing network, with high betweenness centrality in temporally changing functional communities. Compared with intention-oriented actions, identification of unintelligible action intention particularly induces stronger OPDC from right superior frontal to inferior frontal gyrus and from sensorimotor to right frontotemporal regions during mentalizing inference process. Conclusion: These findings collectively suggest that, in the time ordering of information transfer within the directed networks, frontal area plays an important role of bridging hub between mirror and mentalizing systems, from maintaining and supervising perceptual information for mirror matching to controlling the mentalizing process for decoding other's action intention.

Behaviorally-relevant features of observed actions dominate cortical representational geometry in natural vision.

We effortlessly extract behaviorally relevant information from dynamic visual input in order to understand the actions of others. In the current study, we develop and test a number of models to better understand the neural representational geometries supporting action understanding. Using fMRI, we measured brain activity as participants viewed a diverse set of 90 different video clips depicting social and nonsocial actions in real-world contexts. We developed five behavioral models using arrangement tasks: two models reflecting behavioral judgments of the purpose (transitivity) and the social content (sociality) of the actions depicted in the video stimuli; and three models reflecting behavioral judgments of the visual content (people, objects, and scene) depicted in still frames of the stimuli. We evaluated how well these models predict neural representational geometry and tested them against semantic models based on verb and nonverb embeddings and visual models based on gaze and motion energy. Our results revealed that behavioral judgments of similarity better reflect neural representational geometry than semantic or visual models throughout much of cortex. The sociality and transitivity models in particular captured a large portion of unique variance throughout the action observation network, extending into regions not typically associated with action perception, like ventral temporal cortex. Overall, our findings expand the action observation network and indicate that the social content and purpose of observed actions are predominant in cortical representation.

Caring for calves: Canadian public perspectives of calf handling methods during spring processing

In North American beef production, handling and restraint of young calves is integral to animal welfare and management practices. This study used a mixed-method approach to gather public perceptions of three handling and restraint methods common in western Canada during spring processing (TT—tilt table, RW—roping and wrestling, and NF—roping and NordFork). Canadians (n = 551) participated in an online survey that included videos of each handling method to ascertain preferences and acceptability. Participants were given industry information about handling and restraint or generic information regarding hay as a control information statement within the topic of agriculture. The survey also collected information about knowledge of the beef industry, animal welfare, and empathy toward animals. The reasons for preferences for specific handling methods were described as the presence of a perceived positive attribute and the absence of a perceived negative for most preferred methods, and inversely when explaining the least preferred method. The main themes focused on the calf’s experience, perception of handler actions, and pragmatic balancing of needs for a good life for the calf. All methods were rated as more acceptable for participants that ate meat consistently, knew more about the beef industry, and, to a lesser extent, if the individual had a lower animal empathy score. Acceptability was not affected by providing information about the practices; however, information did elicit more pragmatic reasoning. Most participants preferred TT over NF and RW (p < 0.001) and found TT more acceptable as well (p < 0.001). The TT was the most preferred method due to calf experience and human handling—notably the absence of dragging a calf, which was predominant in why participants selected NF or RW as their least preferred method. Consistency of themes highlights that regardless of method or acceptability, the fundamental expectation of the public focuses on the perception of the calf’s quality of life, humane handling, and pragmatism, which are values aligned with beef sustainability initiatives.

Regulator of G protein signalling 14 (RGS14) protein expression profile in the adult mouse brain.

Regulator of G protein signalling 14 (RGS14) is a multifunctional signalling protein that serves as a natural suppressor of synaptic plasticity in the mouse brain. Our previous studies showed that RGS14 is highly expressed in postsynaptic dendrites and spines of pyramidal neurons in hippocampal area CA2 of the developing mouse brain. However, our more recent work with monkey brain shows that RGS14 is found in multiple neuron populations throughout hippocampal area CA1 and CA2, caudate nucleus, putamen, globus pallidus, substantia nigra and amygdala. In the mouse brain, we also have observed RGS14 protein in discrete limbic regions linked to reward behaviour and addiction, including the central amygdala and the nucleus accumbens, but a comprehensive mapping of RGS14 protein expression in the adult mouse brain is lacking. Here, we report that RGS14 is more broadly expressed in mouse brain than previously known. Intense RGS14 staining is observed in specific neuron populations of the hippocampal formation, amygdala, septum, bed nucleus of stria terminalis and ventral striatum/nucleus accumbens. RGS14 is also observed in axon fibre tracts including the dorsal fornix, fimbria, stria terminalis and the ventrohippocampal commissure. Moderate RGS14 staining is observed in various other adjacent regions not previously reported. These findings show that RGS14 is expressed in brain regions that govern aspects of core cognitive functions such as sensory perception, emotion, memory, motivation and execution of actions and suggest that RGS14 may serve to suppress plasticity and filter inputs in these brain regions to set the overall tone on experience-to-action processes.

Visual attention modulates mu suppression during biological motion perception in autistic individuals.

There has been a lot of controversy regarding mirror neuron function in autism spectrum disorder (ASD), in particular during the observation of biological motions (BM). Here, we directly explored the link between visual attention and brain activity in terms of mu suppression, by simultaneously recording eye-tracking and EEGs during BM tasks. Nineteen autistic children (15 boys, mean age = 11.57 ± 4.28 years) and 19 age-matched neurotypical (NT) children (15 boys, mean age = 11.68 ± 5.22 years) participated in the study. Each participant's eye movement and EEG were simultaneously recorded while watching four BM stimuli (walking, cartwheeling, free-throwing and underarm throwing) and a scrambled condition. Mu (8-13 Hz) suppression index (SI) for central regions was calculated. Fixation counts and percent of fixation time were calculated as indices of eye movements. EEG results revealed significant mu suppressions in the central region in both groups for all BM actions. Eye-tracking results showed that NT children had greater fixation counts and a higher percentage of fixation time than autistic children, indicating greater overall visual attention to BM. Notably, correlational analyses for both groups further revealed that individuals' fixation time and fixation counts were negatively correlated with the mu suppression index for all actions, indicating a strong association between visual attention and mu SI in the central region. Our findings suggest a critical role of visual attention in interpreting mu suppression during action perception in autism.

IDEOGRAPHIC MODELLING OF THE EMOTIONAL PICTURE OF THE WORLD IN ENGLISH PHRASEOLOGY

Emotion is a mental reflection in the form of a direct biased experience of the content of life phenomena and situations, caused by the relation of their objective properties to the needs of the subject. Emotions are essential components of life activity, a powerful means of activating the sensory and perceptual activity of the individual. In the theory of activity, they are defined as a reflection of the relationship between the result of an activity and its motive. If the activity is successful in terms of the motive, positive emotions (interest, satisfaction) arise, and if it is unsuccessful, negative emotions arise. Emotions arise only in connection with events or results of actions that are related to motives. The highest product of the development of human emotions is strong feelings for objects that meet one’s highest needs. A strong, absolutely dominant feeling is called passion. Events signalling possible changes in a person’s life, along with specific emotions, can cause changes in the general emotional background – mood. The attitude to the reflected phenomena as the main property of emotions is presented: 1) in their qualitative characteristics, which include: a) sign – positive, negative; b) modality – anger, contempt, embarrassment, guilt, interest, sadness, surprise, disgust, pleasure, fear, shame; 2) in the dynamics of the course of emotions themselves – duration, intensity, etc.; 3) in the dynamics of external expression of emotions – emotional expression – in facial expressions, speech, pantomime.

Factors Impacting Plant-Based Meat Product Consumption: A Consumer Survey Conducted in a New First-Tier City in China.

In recent years, the worldwide plant-based meat sector has undergone substantial and rapid expansion. The swift advancement of plant-based meat products in the Chinese market is ascribed to changes in customer dietary preferences. To accelerate the rapid expansion of China's plant-based meat sector, it is essential to conduct research on consumer demand trends. Citespace was utilized in this study to conduct a bibliometric analysis of research pertaining to plant-based meat. A study model was then created to analyze the primary elements affecting the consumption behavior of plant-based meat products. This study employs Zhengzhou as a case study to construct a research model to examine consumers' inclination to purchase plant-based meat products. The model is derived from survey data obtained from 570 consumers. The findings indicate that the characteristics of plant-based meat products significantly influence consumers' purchase intentions and consumption behaviors by shaping their perceptual activity. Price rationality, technical security, and flavor richness are three principal factors influencing customer purchasing of plant-based meat products. The perceived value and trust of consumers can somewhat mediate the influence of plant-based meat consumption behavior. This study offers significant insights into purchasing intentions and consumer behavior in first-tier cities in China. The outcomes of this study can provide a beneficial framework for imitation meat producers to improve product development and stimulate customer interest in the plant-based meat market.

FACTORS INFLUENCING STUDENT PERCEPTIONS OF TAX EVASION

This study aims to examine the factors that influence students' perceptions of ethical tax evasion actions. The population of this study were students majoring in accounting and tax administration at the Faculty of Economics and Business, Universitas Sultan Ageng Tirtayasa. Sampling was carried out based on purposive sampling with the type of judgment. The stages in this study were carried out by collecting data through questionnaires distributed to accounting and tax administration students who had taken taxation courses and continued with data analysis. The data of this study are primary data and were analyzed using validity tests, reliability tests, normality tests, multicollinearity tests, heteroscedasticity tests and multiple linear regression analysis tests. The results of this study indicate that the taxation system and money ethic have a positive and significant effect on the ethical perception of tax evasion. While the variables of fairness and tax sanctions have a negative effect on the ethical perception of tax evasion. The results of this study also show that the four variables together can influence the ethical perception of tax evasion actions.

Empathy at the heart of customer experience: A holistic framework for understanding and enhancing consumer empathy through the lens of customer experience

AbstractServing as a social glue in interactions, consumer empathy takes center stage in shaping a pleasant customer experience. Our holistic framework of an empathic customer experience, rooted in the perception–action model of empathy and established customer experience conceptualizations, unveils the close interrelationship between consumer empathy and customer experiences. Grounded in a systematic literature review and a conceptual synthesis, our study contributes to customer experience research by conceptualizing consumer empathy as a cognitive and affective customer experience response, potentially accompanied by supplementary customer experience responses, which we refer to as an empathic customer experience. This study advances empathy literature by offering a systematic overview of an empathic customer experience, covering stimuli at touchpoints that induce an empathic customer experience during consumer interactions, potential contextual factors, and evaluative outcomes of an empathic customer experience. From our results, we derive an agenda with several research directions for the joint investigation of consumer empathy and customer experience to contribute to both research fields. In addition, our framework provides insights for managers, including recommendations for designing stimuli to evoke an empathic customer experience.

Human risk recognition and prediction in manned submersible diving tasks driven by deep learning models

The complexity of human cognition is increased by the multiple and interactive information clusters brought about by the application of advanced intelligent information technologies. Especially in systems operating in extreme regions far from society, human errors are more pronounced than ever before. Prolonged social isolation, extreme weightless or overweight environments, stressful atmospheres, and lack of situational awareness are all added potential elements contributing to human risk. Although the development of human reliability analysis methods and their variants continues to mature, accurately predicting the potential risk of dynamic human behavior from sparse and discrete events remains a great challenge. We focus on deep learning computational architectures that are similar to the cognitive processes and mechanisms of the brain, and build neural networks that match the perceptual activation and memory cycling of the cognitive features of the brain. This study focuses on investigating the ability of the joint SNN-ITLSTM network to predict human error behavior and the clusters of performance shaping factors that effectively characterize the far-social nature. Combining the bionic properties of SNN and the temporal update mechanism of LSTM in the form of hierarchical events constitutes a computationally efficient network architecture. Our results show that the joint model proposed in this study has the performance to strengthen temporal influences and characterize cognitive features of the brain.

SPANet: Spatial perceptual activation network for camouflaged object detection

AbstractCamouflaged object detection (COD) aims to segment objects embedded in the environment from the background. Most existing methods are easily affected by background interference in cluttered environments and cannot accurately locate camouflage areas, resulting in over‐segmentation or incomplete segmentation structures. To effectively improve the performance of COD, we propose a spatial perceptual activation network (SPANet). SPANet extracts the spatial positional relationship between each object in the scene by activating spatial perception and uses it as global information to guide segmentation. It mainly consists of three modules: perceptual activation module (PAM), feature inference module (FIM), and interaction recovery module (IRM). Specifically, the authors design a PAM to model the positional relationship between the camouflaged object and the surrounding environment to obtain semantic correlation information. Then, a FIM that can effectively combine correlation information to suppress background interference and re‐encode to generate multi‐scale features is proposed. In addition, to further fuse multi‐scale features, an IRM to mine the complementary information and differences between features at different scales is designed. Extensive experimental results on four widely used benchmark datasets (i.e. CAMO, CHAMELEON, COD10K, and NC4K) show that the authors’ method outperforms 13 state‐of‐the‐art methods.

263 Public perspectives of calf handling: A survey of Canadians

Abstract In North American beef production handling and restraint of young calves is integral to animal welfare and management practices. This study used a mixed method approach to gather public perceptions of three handling and restraint methods common on beef operations in western Canada (RW - Roping and Wrestling, NF – roping and NordForks, and TT – Tilt Table). Canadian participants (n = 551) recruited by CloudResearch to represent the national demographics participated in an online survey that included videos of each handling method to ascertain preferences and acceptability. Prior to watching the videos, participants were given industry information about handling and restraint or generic information regarding hay as a control information statement within the topic of agriculture. The survey also collected information about knowledge of the beef industry, animal welfare, and empathy toward animals. The reasons for preferences were described as presence of a perceived positive attribute and absence of a perceived negative for most preferred methods, and inversely when explaining least preferred method. The findings focused on calf’s experience, perception of handler actions, and pragmatic balancing of handler needs and a good life for the calf. Methods were rated as more acceptable for participants that ate meat consistently, knew more about the beef industry, and, to a lesser extent, if the individual had a lower animal empathy score (Table 1). Acceptability was not affected by providing information about the practices; however, information about handling and restraint did elicit more pragmatic reasoning. Most participants preferred TT over NF and RW (P < 0.001) and found TT more acceptable as well (P < 0.001). The TT was the most preferred method due to calf experience and human handling, notably the absence of dragging a calf, which was predominant in why participants selected NF or RW as their least preferred method. Consistency of themes highlights that the Canadian public has a fundamental expectation of value for the quality of life of the calf, humane handling, and pragmatism which aligns with beef sustainability initiatives and represent points of connection for building trust between industry and the public.

Re-enactment and embodied resonance in episodic memory: reconciling phenomenological approaches and constructive theories

AbstractThis paper investigates the embodied dimensions of episodic memory through a phenomenological analysis. Contemporary philosophical theories understand episodic memory as a mental representation of a past event ‘happening in the head’. A philosophical account that seemingly supports an embodied understanding of episodic memory comes from phenomenology. Phenomenology has traditionally understood episodic memory in terms of presentification, which implies a reproduction of the elapsed portion of the consciousness lived during the foreground experience, replicating the previous perceptual activity. However, this appears to be incoherent with the constructive theories of episodic memory, which highlight how subjects shift perspectives in memory or include information not present in the foregoing experience. Thus, according to these contemporary theories, episodic memory is unlikely to imply a replay of the past conscious experience. I argue that if we investigate the embodied dimensions, then it is possible to reconcile the phenomenological approach and the constructive theories. More precisely, I ground the investigation on the analysis of operative intentionality and its role in comparing procedural and episodic memory. I argue that two embodied features qualify the reproductive modification of consciousness: the flexible re-enactment of the previous operative intentionality and the pre-reflective mode of embodied resonance with an agent I am no longer.

The Impact of Perception-Action Training Devices on Quickness and Reaction Time in Female Volleyball Players.

The objective of this study was to examine the effect of a training program utilizing action perception technology (PAD) tools on improving the motor reaction times and neuromuscular capabilities of the upper and lower limbs compared to a traditional training program. Twenty-four female volleyball players competing in the Italian national championship were randomized into two groups of 12 athletes each: an experimental group (EG) and a control group (CG). A preliminary analysis confirmed the absence of significant differences in age and anthropometric characteristics between the groups. All the players underwent an initial battery of tests (pre-test), including Reaction Time simple Upper and Lower Limb (RTsUL and RTsLL) and Tapping Upper and Lower Limb (TUL and TLL). During a 6-week training program, the experimental group used exercises with a technological system of illuminated disks, while the control group followed the traditional training methods without advanced technology. At the end of the program, both groups were subjected to final tests (post-test). The main results show that after 6 weeks, both groups improved their performance compared to the initial tests. However, EG achieved significantly better results than CG in every test, with significant reductions in average times (ip%) of -14.9% in RTsUL (DX = -0.072 s, t = 23.2, p < 0.05, d = 6.7), -14.9% in RTsLL (DX = -0.091 s, t = 44.0, p < 0.05, d = 12.7), -10.6% in TUL (DX = -0.622 s, t = 42.0, p < 0.05, d = 12.1), and -10.7% in TLL (DX = -0.983 s, t = 43.1, p < 0.05, d = 12.4). The use of light-based perception-action technology devices in volleyball training has shown potential for significantly improving movement speed and reaction time. However, further research is needed to determine whether these improvements actually translate into enhanced overall performance in competitive contexts compared to the traditional training methods.

How bipedalism shapes humans' actions with hand tools.

The task for an embodied cognitive understanding of humans' actions with tools is to elucidate how the human body, as a whole, supports the perception of affordances and dexterous action with objects in relation to other objects. Here, we focus on the relationship between humans' actions with handheld tools and bipedal posture. Posture plays a pivotal role in shaping animals' perception and action dynamics. While humans stand and locomote bipedally, other primates predominantly employ quadrupedal postures and locomotion, relying on both hands and feet to support the body. Drawing upon evidence from evolutionary biology, developmental psychology and performance studies, we elucidate the influence of bipedalism on our actions with objects and on our proficiency in using tools. We use the metaphor of cascades to capture the dynamic, nonlinear transformations in morphology and behaviour associated with posture and the use of tools across evolutionary and developmental timescales. Recent work illustrates the promise of multifractal cascade analysis to reveal nonlinear, cross-scale interactions across the entire body in real-time, supporting the perception of affordances for actions with tools. Cascade analysis enriches our comprehension of real-time performance and facilitates exploration of the relationships among whole-body coordination, individual development, and evolutionary processes.This article is part of the theme issue 'Minds in movement: embodied cognition in the age of artificial intelligence'.

SmartDetector: Automatic and vision-based approach to point-light display generation for human action perception.

Over the past four decades, point-light displays (PLD) have been integrated into psychology and psychophysics, providing a valuable means to probe human perceptual skills. Leveraging the inherent kinematic information and controllable display parameters, researchers have utilized this technique to examine the mechanisms involved in learning and rehabilitation. However, classical PLD generation methods (e.g., motion capture) are difficult to apply for behavior analysis in real-world situations, such as patient care or sports activities. Therefore, there is a demand for automated and affordable tools that enable efficient and real-world-compatible generation of PLDs for psychological research. In this paper, we propose SmartDetector, a new artificial intelligence (AI)-based tool for automatic PLD creation from RGB videos. To evaluate humans' perceptual skills for processing PLD building with SmartDetector, 126 participants were randomly assigned to recognition, discrimination, or detection tasks. Results demonstrated that, irrespective of the task, PLDs generated by SmartDetector exhibited commendable perceptual performance in terms of accuracy and response times compared to literature findings. Moreover, to enhance usability and broaden accessibility, we developed an intuitive web interface for our method, making it available to a wider audience. The resulting application is available at https://plavimop.prd.fr/index.php/en/automatic-creation-pld . SmartDetector offers interesting possibilities for using PLD in research and makes the use of PLD more accessible for nonacademic applications.

Enhancing Patient Understanding of Laboratory Test Results: Systematic Review of Presentation Formats and Their Impact on Perception, Decision, Action, and Memory.

Direct access of patients to their web-based patient portal, including laboratory test results, has become increasingly common. Numeric laboratory results can be challenging to interpret for patients, which may lead to anxiety, confusion, and unnecessary doctor consultations. Laboratory results can be presented in different formats, but there is limited evidence regarding how these presentation formats impact patients' processing of the information. This study aims to synthesize the evidence on effective formats for presenting numeric laboratory test results with a focus on outcomes related to patients' information processing, including affective perception, perceived magnitude, cognitive perception, perception of communication, decision, action, and memory. The search was conducted in 3 databases (PubMed, Web of Science, and Embase) from inception until May 31, 2023. We included quantitative, qualitative, and mixed methods articles describing or comparing formats for presenting diagnostic laboratory test results to patients. Two reviewers independently extracted and synthesized the characteristics of the articles and presentation formats used. The quality of the included articles was assessed by 2 independent reviewers using the Mixed Methods Appraisal Tool. A total of 18 studies were included, which were heterogeneous in terms of study design and primary outcomes used. The quality of the articles ranged from poor to excellent. Most studies (n=16, 89%) used mock test results. The most frequently used presentation formats were numerical values with reference ranges (n=12), horizontal line bars with colored blocks (n=12), or a combination of horizontal line bars with numerical values (n=8). All studies examined perception as an outcome, while action and memory were studied in 1 and 3 articles, respectively. In general, participants' satisfaction and usability were the highest when test results were presented using horizontal line bars with colored blocks. Adding reference ranges or personalized information (eg, goal ranges) further increased participants' perception. Additionally, horizontal line bars significantly decreased participants' tendency to search for information or to contact their physician, compared with numerical values with reference ranges. In this review, we synthesized available evidence on effective presentation formats for laboratory test results. The use of horizontal line bars with reference ranges or personalized goal ranges increased participants' cognitive perception and perception of communication while decreasing participants' tendency to contact their physicians. Action and memory were less frequently studied, so no conclusion could be drawn about a single preferred format regarding these outcomes. Therefore, the use of horizontal line bars with reference ranges or personalized goal ranges is recommended to enhance patients' information processing of laboratory test results. Further research should focus on real-life settings and diverse presentation formats in combination with outcomes related to patients' information processing.
