Allocentric spatial representations dominate when switching between real and virtual worlds Open
After removing a virtual reality headset, people can be surprised to find that they are facing a different direction than expected. Here, we investigated if people can maintain spatial representations of one environment while immersed in a…

Head engagement during visuomotor tracking is determined by postural challenges and aging Open
Head movements are important for gaze shifts. However, when keeping balance, mechanical torques from such movements can have detrimental effects. Here, we used a visual pursuit task and showed that, as postural challenge increases, young p…

Avoiding Spiders: Affective Context Shapes Tactile Suppression During Movement Open
Tactile sensitivity is typically reduced during voluntary movements, a phenomenon known as tactile suppression. While affective context is known to modulate tactile processing, it remains unclear how it influences tactile suppression. In a…

Characterizing SEPs from Pacinian-targeted vibrations Open
Somatosensory-evoked potentials (SEPs) are commonly studied using transcutaneous nerve stimulation, which does not reflect the selective engagement of mechanoreceptors in natural touch. Here, we use naturalistic vibrotactile stimuli to sel…

Modulation of tactile sensitivity in the lower limbs during goal-directed movements Open
Tactile sensitivity drops in a moving than static limb due to a combination of central, predictive mechanisms and peripheral effects. This suppression is dynamically modulated during movement, as shown during upper-limb actions, yet little…

The effect of vection on the use of optic flow cues Open
When we move objects move past us in a relative pattern of motion referred to as optic flow. Modulations in optic flow can impact both our perception of self-motion (e.g. perceived distance travelled) and our feeling of self-motion, referr…

Reliability of Tactile Perception and Suppression Measurements Open
Tactile signals arising on one's own body allow estimation of one's sensory state and foster interactions with the environment. However, tactile perception can be influenced by various factors. For instance, tactile perception is suppresse…

Haptic size perception is influenced by body and object orientation Open
Changes in body orientation from standing have been shown to impact our perception of visual size. This has been attributed to the vestibular system’s involvement in constructing a representation of the space around our body. In the curren…

Recalibration of perceived agency transfers across modalities Open
We experience our actions and their sensory consequences as synchronous despite small sensorimotor delays. This is attained by an adaptation process in which the sensorimotor system recalibrates temporal discrepancies between actions and t…

Head engagement during visuomotor tracking is determined by postural demands and aging Open
Vision is important for various tasks, from visually tracking moving objects to maintaining balance. People obtain visual information through eye movements performed either alone or in combination with head movements. Even when isolated ey…

Modelling sensory attenuation as Bayesian causal inference across two datasets Open
Introduction To interact with the environment, it is crucial to distinguish between sensory information that is externally generated and inputs that are self-generated. The sensory consequences of one’s own movements tend to induce attenua…

Postural demands modulate tactile perception in the lower limb in young and older adults Open
Balance control requires constant integration of feedforward and feedback signals. In healthy aging, the quality of feedback signals decreases while feedforward control is upweighted; but it is unclear how tactile perception is modulated w…

Object center of mass predicts pointing endpoints in virtual reality Open
Introduction Humans point using their index finger to intuitively communicate distant locations to others. This requires the human sensorimotor system to select an appropriate target location to guide the hand movement. Mid-air pointing ge…

Where was this thing again? Evaluating methods to indicate remembered object positions in virtual reality Open
A current focus in sensorimotor research is the study of human perception and action in increasingly naturalistic tasks and visual environments. This is further enabled by the recent commercial success of virtual reality (VR) technology, w…

The (Un)ideal Physicist: How Humans Rely on Object Interaction for Friction Estimates Open
To estimate object properties such as mass or friction, our brain relies on visual information to efficiently compute approximations. The role of sensorimotor feedback, however, is not well understood. Here we tested healthy adults ( N = 7…

How visuomotor predictability and task demands affect tactile sensitivity on a moving limb during object interaction in a virtual environment Open
Tactile sensitivity is decreased on a moving limb compared to the same static limb. This tactile suppression likely reflects an interplay between sensorimotor predictions and sensory feedback. Here, we examined how visuomotor predictabilit…
