Do peripersonal space for acting on objects and interpersonal interacting with con-specifics share common mechanisms reflect the social valence of stimuli? To answer this question, we investigated whether these spaces refer to a similar or different physical distance.Participants provided reachability-distance (for potential action) comfort-distance processing) judgments towards human non-human virtual stimuli while standing still (passive) walking toward (active).Comfort-distance was larger...

In the context of Covid-19 pandemic, barrier gestures such as regular hand-washing, social distancing, and wearing a face mask are highly recommended. Critically, interpersonal distance (IPD) depends on affective dimension interaction, which might be affected by current context. present internet-based experimental study, we analyzed preferred IPD 457 French participants when facing human-like characters that were either or displaying neutral, happy angry facial expression. Results showed was...

Accurate control of interpersonal distances in social contexts is an important determinant effective interactions. Although comfortable distance seems to be dependent on factors such as the gender, age and activity confederates, it also modulated by way we represent our peripersonal-action space. To test this hypothesis, present study investigated relation between emotional responses registered through electrodermal (EDA) triggered human-like point-light displays (PLDs) carrying different...

The peripersonal space is an adaptive and flexible interface between the body environment that fulfills a dual-motor function: preparing for voluntary object-oriented actions to interact with incentive stimuli defensive responses when facing potentially harmful stimuli. In this position article, we provide arguments sensorimotor rooting of representation highlight variables contribute its characteristics. We also demonstrate represents mediation zone contributing not only control...

This book collates the most up to date evidence from behavioural, brain imagery and stroke-patient studies, discuss ways in which cognitive neural processes are responsible for language processing. Divided into six sections, edited volume presents arguments evolutionist, developmental, behavioural neurobiological perspectives, all of point a strong relationship between action language. It provides scientific basis new theoretical approach evolution, acquisition use humans, whilst at same...

Background Visually determining what is reachable in peripersonal space requires information about the egocentric location of objects but also possibilities action with body, which are context dependent. The aim present study was to test role motor representations visual perception space. Methodology Seven healthy participants underwent a TMS while performing right-left decision (control) task or perceptually judging whether target not their right hand. An actual grasping movement included....

The present functional magnetic resonance imaging (fMRI) study investigates the neural correlates of reachability judgements. In a block design experiment, 14 healthy participants judged whether visual target presented at different distances in virtual environment display was reachable or not with right hand. two control tasks, they colour relative position according to flankers. Contrasting activations registered judgement task and we found frontal structures, bilateral inferior superior...

Optimal control models of biological movements are used to account for those internal variables that constrain voluntary goal-directed actions. They however do not take into external environmental constraints as associated social intention. We investigated here the effects context on kinematic characteristics sequential actions consisting in placing an object initial pad (preparatory action) before reaching and grasping fast possible move it another location (main action). Reach-to-grasp...

Abstract The space around the body crucially serves a variety of functions, first and foremost, preserving one’s own safety avoiding injury. Recent research has shown that emotional information, in particular threatening facial expressions, affects regulation peripersonal-reaching (PPS, for action with objects) interpersonal-comfort (IPS, social interaction). Here we explored if expressions may similarly or differently affect both spaces terms psychophysiological reactions (cardiac...

Patients with right hemispheric stroke usually present an anticlockwise deviation of the subjective visual vertical (SVV) in frontal (roll) plane. However, occurrence a similar disorder sagittal (pitch) plane has never been assessed. We investigated both planes those patients.Eight patients, 4 spatial neglect (N+) and without (N-), were compared healthy participants (C). They sat facing luminous bar adjustable rotation, either roll or pitch plane, had to orient it position, dark.Compared N-...

This study examines whether the perception of peripersonal action-space and interpersonal social-space is modified in patients with restrictive-type anorexia two experimental conditions using videos. First, participants stopped video an approaching stimulus when they felt distance to be comfortable for interacting it (first-person perspective). Second, observed individual a stimulus, or being approached by it, was at (third-person In first-person perspective, results showed estimation space...
