Prism adaptation may alleviate some symptoms of spatial neglect. However, the mechanism
through which this technique works is still unclear. This study investigated whether prism
adaptation differentially affects dysfunction in perceptual-attentional 'where'bias versus
motor-intentional 'aiming'bias. Five neglect patients performed a line bisection task in which
lines were viewed under both normal and right–left reversed viewing conditions, allowing for
the fractionation of 'where'and 'aiming'spatial bias components. After two consecutive days …
