In the Rubber Hand Illusion, feeling of ownership a rubber hand displaced from participant's real occluded is evoked by synchronously stroking both hands with paintbrushes. A change perceived finger location towards (proprioceptive drift) has been reported to correlate this illusion. To measure time course proprioceptive drift during we regularly interrupted (performed robot arms) location. Measurements were made projecting probe dot into field view (using semi-transparent mirror) and asking...

The concept of agency is crucial importance in cognitive science and artificial intelligence, it often used as an intuitive rather uncontroversial term, contrast to more abstract theoretically heavily weighted terms such intentionality , rationality, or mind. However, most the available definitions are too loose unspecific allow for a progressive scientific research program. They implicitly unproblematically assume features that characterize agents, thus obscuring full potential challenge...

Humans combine redundant multisensory estimates into a coherent multimodal percept. Experiments in cue integration have shown for many modality pairs and perceptual tasks that information is fused statistically optimal manner: observers take the unimodal sensory reliability consideration when performing judgments. They senses according to rules of Maximum Likelihood Estimation maximize overall precision. This tutorial explains an accessible manner how design experiments analyse results from...

Latency between a user's movement and visual feedback is inevitable in every Virtual Reality application, as signal transmission processing take time. Unfortunately, high end-to-end latency impairs perception motor performance. While it possible to reduce delay tens of milliseconds, these delays will never completely vanish. Currently, there gap literature regarding the impact on performance well their interplay virtual environments employing full-body avatars. With present study at hand, we...

A difference in skin temperature between the hands has been identified as a physiological correlate of rubber hand illusion (RHI). The RHI is an body ownership, where participants perceive ownership over if they see it being stroked synchrony with their own occluded hand. current study set out to replicate this result, i.e., psychologically induced cooling stimulated using automated stroking paradigm, stimulation was delivered by robot arm (PHANToMTM force-feedback device). After we found no...

Researchers in social cognition increasingly realize that many phenomena cannot be understood by investigating offline situations only, focusing on individual mechanisms and an observer perspective. There are processes of dynamic emergence specific to online situations, when two or more persons engaged a real-time interaction than just the sum capacities behaviours, these require study interaction. Auvray et al.'s (2009) perceptual crossing paradigm offers possibly simplest for studying such...

In case of delayed visual feedback during visuomotor tasks, like in some sluggish computer games, humans can modulate their behavior to compensate for the delay.However, opinions on nature this compensation diverge.Some studies suggest that adapt delays with lasting changes motor (aftereffects) and a recalibration time perception.Other have shown little or no evidence such semipermanent temporal domain.We hypothesize predictability reference signal (target be tracked) is necessary delay...

Studies on human recalibration of perceived visuo-motor simultaneity so far have been limited to the study movement-lead temporal discrepancies (visual lags). We studied adaptation both vision-lead and discrepancies, test for differences between these conditions, as a leading visual stimulus violates underlying cause-effect structure. To this end, we manipulated relationship motor action (button press) event (flashed disk) in training phase. Participants were tested order judgment task (PSS)...

Classically, the question of recognizing another subject is posed unilaterally, in terms observed behaviour other entity. Here, we propose an alternative, based on emergent patterns activity resulting from interaction both partners. We employ a minimalist device which forces subjects to externalize their perceptual as trajectories can be and recorded; results show that do identify situation crossing with partner. The interpretation guided by comparable evolutionary robotics simulations....

The plasticity of the human nervous system allows us to acquire an open-ended repository sensorimotor skills in adulthood, such as mastery tools, musical instruments or sports. How novel are learned from scratch is yet largely unknown. In particular, so-called inverse mapping goal states motor underdetermined because a can often be achieved by many different movements (motor redundancy). humans learn resolve redundancy and which principles they explore high-dimensional spaces has hardly been...
