Perceived reachability: the roles of handedness and hemifield

The impact of reaching experience on the ability to predict one’s own reaching range was investigated. Left- and right-handed participants made verbal estimates about the reachability of a target object for both arms in ipsilateral and contralateral frontal space. There was a significant overestimation bias in both groups and for both hands. The overestimation bias increased with the target object’s eccentricity in contralateral space. The implications of these findings for models of motor control and motor imagery are discussed.
