Visual processing is biased in peripersonal foot space.
Objects in peripersonal space are of great importance for interaction with the sensory world. A variety of research exploring sensory processing in peripersonal space has produced extensive evidence for altered vision near the hands. However, visual representations of the peripersonal space surrounding the feet remain unexplored. In a set of four experiments, we investigated whether observers e...
متن کاملVisual peripersonal space centred on the face in humans.
A convergent series of studies in monkeys and man suggests that the computation of visual space is performed in several brain regions for different behavioural purposes. Among these multiple spatial areas, the ventral intraparietal cortex, the putamen and the ventral aspect of the premotor cortex (area 6) contain a system for representing visual space near the face (peripersonal space). In thes...
متن کاملTouch dominates haptic estimates of discordant visual-haptic size.
Observers (72 college students) estimated the size of plastic squares that they held in their fingers and simultaneously viewed through a reducing lens that halved the squares' visual size. The squares were grasped from below through a cloth that prevented direct sight of the hand. Each estimate was a match selected later, either haptically or visually, from a set of comparison squares. Vision ...
متن کاملI feel who I see: visual body identity affects visual-tactile integration in peripersonal space.
Recent studies have shown the importance of integrating multisensory information in the body representation for constituting self-consciousness. However, one idea that has received only scant attention is that our body representation is also constituted by knowledge of bodily visual characteristics (i.e. 'what I look like'). Here in two experiments we used a full body crossmodal congruency task...
متن کاملGrasping actions remap peripersonal space.
The portion of space that closely surrounds our body parts is termed peripersonal space, and it has been shown to be represented in the brain through multisensory processing systems. Here, we tested whether voluntary actions, such as grasping an object, may remap such multisensory spatial representation. Participants discriminated touches on the hand they used to grasp an object containing task...
