Tool-Use: Capturing Multisensory Spatial Attention or Extending Multisensory Peripersonal Space?

Tool-use: capturing multisensory spatial attention or extending multisensory peripersonal space?

The active and skilful use of tools has been claimed to lead to the "extension" of the visual receptive fields of single neurons representing peripersonal space--the visual space immediately surrounding one's body parts. While this hypothesis provides an attractive and potentially powerful explanation for one neural basis of tool-use behaviours in human and nonhuman primates, a number of compet...

The Body Schema And The Multisensory Representations Of Peripersonal Space

Others have shown that the body schema plays a role in explicit and implicit distance The space near the body and within reach (peripersonal space) is closely If a multisensory implicit body representation is mediating reaching distance.

Peripersonal Space: a Multisensory Interface for Body-objects Interactions

On the relative contributions of multisensory integration and crossmodal exogenous spatial attention to multisensory response enhancement.

Two processes that can give rise to multisensory response enhancement (MRE) are multisensory integration (MSI) and crossmodal exogenous spatial attention. It is, however, currently unclear what the relative contribution of each of these is to MRE. We investigated this issue using two tasks that are generally assumed to measure MSI (a redundant target effect task) and crossmodal exogenous spatia...

Effects of spatial and selective attention on basic multisensory integration.

When participants respond to auditory and visual stimuli, responses to audiovisual stimuli are substantially faster than to unimodal stimuli (redundant signals effect, RSE). In such tasks, the RSE is usually higher than probability summation predicts, suggestive of specific integration mechanisms underlying the RSE. We investigated the role of spatial and selective attention on the RSE in audio...
