In case of doubt, one follows one's self: the implicit guidance of the embodied self-avatar

Ronan Boulic, Bruno Herbelin, Loën Boban

The sense of embodiment in virtual reality (VR) is commonly understood as the subjective experience that one's physical body is substituted by a virtual counterpart, and is typically achieved when the avatar's body, seen from a first-person view, moves lik ...

Neurocognition and NMDAR co-agonists pathways in individuals with treatment resistant first-episode psychosis: a 3-year follow-up longitudinal study

Lijing Xin, Kim Do

This study aims to determine whether 1) individuals with treatment-resistant schizophrenia display early cognitive impairment compared to treatment-responders and healthy controls and 2) N-methyl-D-aspartate-receptor hypofunction is an underlying mechanism ...

The EEG multiverse of schizophrenia

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Janir Nuno Ramos Antunes Da Cruz, Patricia Figueiredo, Wei-Hsiang Lin, Dario Alejandro Gordillo Lopez

Research on schizophrenia typically focuses on one paradigm for which clear-cut differences between patients and controls are established. Great efforts are made to understand the underlying genetical, neurophysiological, and cognitive mechanisms, which ev ...

Rituals of art and science to decompart(mentalize) knowledge

Bruno Herbelin

We here explore the potential of rituals in order to more fully comprehend the subjective mechanisms of listening, leading to a broader understanding of phenomenal consciousness (why and how do I know that I am experiencing something?). The originality of ...

Selective attention involves a feature-specific sequential release from inhibitory gating

David Pascucci, Gijs Plomp

Selective attention is a fundamental cognitive mechanism that allows our brain to preferentially process relevant sensory information, while filtering out distracting information. Attention is thought to flexibly gate the communication of irrelevant inform ...

Modulation of working memory duration by synaptic and astrocytic mechanisms

Sophia Becker

Short-term synaptic plasticity and modulations of the presynaptic vesicle release rate are key components of many working memory models. At the same time, an increasing number of studies suggests a potential role of astrocytes in modulating higher cognitiv ...

Soft Embodiment for Engineering Artificial Limbs

Silvestro Micera

We highlight two alternative, yet complementary, solutions for har-nessing available neural resources for improving integration of artificial limbs (ALs) through embodiment. 'Hard' embodiment exploits neural and cognitive body mechanisms by closely mimicki ...

Perceptual grouping leads to objecthood effects in the Ebbinghaus illusion

Michael Herzog, Aline Françoise Cretenoud, Einat Rashal

The Ebbinghaus illusion is argued to be a product of low-level contour interactions or a higher cognitive comparison process. We examined the effect of grouping on the illusion by manipulating objecthood, i.e., the degree to which an object is a cohesive p ...

Transferring interactive activities in large lectures from face-to-face to online settings

Pierre Dillenbourg, Louis Pierre Faucon, Jennifer Kaitlyn Olsen

Purpose Within higher education, there was an abrupt shift from face-to-face to online lecturing with the introduction of social distancing measures in light of a global pandemic. The purpose of this study is to enrich the connection between students and i ...

The Tonal Diffusion Model

Martin Alois Rohrmeier, Fabian Claude Moss, Robert Lieck

Pitch-class distributions are of central relevance in music information retrieval, computational musicology and various other fields, such as music perception and cognition. However, despite their structure being closely related to the cognitively and musi ...

GEFF: Graph embedding for functional fingerprinting

Enrico Amico

It has been well established that Functional Connectomes (FCs), as estimated from functional MRI (fMRI) data, have an individual fingerprint that can be used to identify an individual from a population (subject-identification). Although identification rate ...

The effects of dual tasks on gait in children with cerebral palsy

Kamiar Aminian, Lena Carcreff, Stéphane Armand

Aim: To assess the gait and cognitive performances of children with cerebral palsy (CP) during dual tasks (DT) in comparison to typically developing (TD) children. Method: This prospective, observational, case-control study included 18 children with CP (7 ...

Congruency effects can compensate for deficits of healthy older adults in crossmodal integration

Friedhelm Christoph Hummel

One of the pivotal challenges of aging is to maintain independence in the activities of daily life. In order to adapt to changes in the environment, it is crucial to continuously process and accurately combine simultaneous input from different sensory syst ...

Interactions of spatial strategies producing generalization gradient and blocking: A computational approach

Ricardo Andres Chavarriaga Lozano

We present a computational model of spatial navigation comprising different learning mechanisms in mammals, i.e., associative, cognitive mapping and parallel systems. This model is able to reproduce a large number of experimental results in different varia ...

Embodiment Sensitivity to Movement Distortion and Perspective Taking in Virtual Reality

Henrique Galvan Debarba

Despite recent technological improvements of immersive technologies, Virtual Reality suffers from severe intrinsic limitations, in particular the immateriality of the visible 3D environment. Typically, any simulation and manipulation in a cluttered environ ...

Cognitive markers as potential endophenotypes for schizophrenia

Michael Herzog, Maya Roinishvili

Schizophrenia is a heterogeneous disease strongly influenced by genetic predisposition. A large variety of candidate genes has been identified of which each gene, however, explains only a small proportion of the genetic risk. For this reason, stable marker ...

Visual Feedback Dominates the Sense of Agency for Brain-Machine Actions

Olaf Blanke, Aaron Schurger, Nathaniel Evans, Steven Gale

Recent advances in neuroscience and engineering have led to the development of technologies that permit the control of external devices through real-time decoding of brain activity (brain-machine interfaces; BMI). Though the feeling of controlling bodily m ...

Multisensory Spatial Mechanisms of the Bodily Self and Social Cognition - A Commentary on Vittorio Gallese and Valentina Cuccio

Christian Pfeiffer

This commentary aims to find the right description of the pre-reflective brain mechanisms underlying our phenomenal experience of being a subject bound to a physical body (bodily self) and basic cognitive, perceptual, and subjective aspects related to inte ...

Cognitive mechanism in synchronized motion: An internal predictive model for manual tracking control

Aude Billard, Mahdi Khoramshahi, Ashwini Shukla

Many daily tasks involve spatio-temporal coordination between two agents. Study of such coordinated actions in human-human and human-robot interaction has received increased attention of late. In this work, we use the mirror paradigm to study coupling of h ...

Emotional contagion for pain is intact in autism spectrum disorders

Nouchine Hadjikhani, Loyse Hippolyte, Ophélie Rogier, Torsten Ruest

Perceiving others in pain generally leads to empathic concern, consisting of both emotional and cognitive processes. Empathy deficits have been considered as an element contributing to social difficulties in individuals with autism spectrum disorders (ASD) ...
