    Learning new sensorimotor contingencies:Effects of long-term use of sensory augmentation on the brain and conscious perception

    Get PDF
    Theories of embodied cognition propose that perception is shaped by sensory stimuli and by the actions of the organism. Following sensorimotor contingency theory, the mastery of lawful relations between own behavior and resulting changes in sensory signals, called sensorimotor contingencies, is constitutive of conscious perception. Sensorimotor contingency theory predicts that, after training, knowledge relating to new sensorimotor contingencies develops, leading to changes in the activation of sensorimotor systems, and concomitant changes in perception. In the present study, we spell out this hypothesis in detail and investigate whether it is possible to learn new sensorimotor contingencies by sensory augmentation. Specifically, we designed an fMRI compatible sensory augmentation device, the feelSpace belt, which gives orientation information about the direction of magnetic north via vibrotactile stimulation on the waist of participants. In a longitudinal study, participants trained with this belt for seven weeks in natural environment. Our EEG results indicate that training with the belt leads to changes in sleep architecture early in the training phase, compatible with the consolidation of procedural learning as well as increased sensorimotor processing and motor programming. The fMRI results suggest that training entails activity in sensory as well as higher motor centers and brain areas known to be involved in navigation. These neural changes are accompanied with changes in how space and the belt signal are perceived, as well as with increased trust in navigational ability. Thus, our data on physiological processes and subjective experiences are compatible with the hypothesis that new sensorimotor contingencies can be acquired using sensory augmentation

    Workplace violence in the COVID-19 era: a qualitative analysis of harassment and threats against public health professionals in Canada

    Objectives This study reports the results of a qualitative study involving public health professionals and documents their experiences with cyberviolence, harassment and threats during the COVID-19 pandemic.Method and analysis The research adopted a discovery-oriented qualitative design, using constructivist grounded theory method and long interview style data collection. Twelve public health professionals from across Canada who held responsibility for COVID-19 response and public health measures in their respective jurisdictions participated. Constant comparative analysis was used to generate concepts through inductive processes.Results Data revealed a pattern that began with mainstream media engagement, moved to indirect cyberviolence on social media that fuelled outrage and polarisation of members of the public, followed by direct cyberviolence in the form of email abuse and threats, and finally resulted in physical threats and confrontation—which were then glorified and amplified on social media. The prolonged nature and intensity of harassment and threats led to negative somatic, emotional, professional and social outcomes. Concerns were raised that misinformation and comments undermining the credibility of public health professionals weakened public trust and ultimately the health of the population. Participants provided recommendations for preventing and mitigating the effects of cyber-instigated violence against public health professionals that clustered in three areas: better supports for public health personnel; improved systems for managing communications; and legislative controls on social media including reducing the anonymity of contributors.Conclusion The prolonged and intense harassment, abuse and threats against public health professionals during COVID-19 had significant effects on these professionals, their families, staff and ultimately the safety and health of the public. Addressing this issue is a significant concern that requires the attention of organisations responsible for public health and policy makers

    Virtual Reality as a Tool to Understand Spatial Navigation

    Spatial navigation, the ability to explore, learn, and remember one’s environment, is a skill that is fundamental to everyday goals. Navigation is challenging to study because it requires understanding and integrating multiple sources of information from the environment and the body as well as many cognitive processes including perception, attention, memory, and decision making. Virtual Reality (VR), the presentation and experience of a synthetic sensory environment, provides a method to study spatial navigation in controlled, ecologically valid, and innovative ways. In this review, we describe VR as a tool to study spatial navigation with the perspective that basic science questions and applications mutually inform one another. We focus on how VR has advanced an understanding of the spatial cues, spatial knowledge, and individual differences involved in spatial navigation and discuss the role and implications of different VR technologies that allow for these investigations

    Establishing a definition of polar bear (\u3ci\u3eUrsus maritimus\u3c/i\u3e) health: A guide to research and management activities

    The meaning of health for wildlife and perspectives on how to assess and measure health, are not well characterized. For wildlife at risk, such as some polar bear (Ursus maritimus) subpopulations, establishing comprehensive monitoring programs that include health status is an emerging need. Environmental changes, especially loss of sea ice habitat, have raised concern about polar bear health. Effective and consistent monitoring of polar bear health requires an unambiguous definition of health. We used the Delphi method of soliciting and interpreting expert knowledge to propose a working definition of polar bear health and to identify current concerns regarding health, challenges in measuring health, and important metrics for monitoring health. The expert opinion elicited through the exercise agreed that polar bear health is defined by characteristics and knowledge at the individual, population, and ecosystem level. The most important threats identified were in decreasing order: climate change, increased nutritional stress, chronic physiological stress, harvest management, increased exposure to contaminants, increased frequency of human interaction, diseases and parasites, and increased exposure to competitors. Fifteen metrics were identified to monitor polar bear health. Of these, indicators of body condition, disease and parasite exposure, contaminant exposure, and reproductive success were ranked asmost important. We suggest that a cumulative effects approach to research and monitoring will improve the ability to assess the biological, ecological, and social determinants of polar bear health and provide measurable objectives for conservation goals and priorities and to evaluate progress
