Resumen
Tactile localization on the involves both a somatotipc a postural schema (bodyschema) representations. The present study determines the extent to wich body posture influences tactile perception in right-damaged patients. Methods: In a first set of experiments, patients were asked to detect single tactile stimulation delivered to their left or right hands or to both hands simultaneously (double stimulation) in diffrenet arm postures. Only patients who had no difficulty localitazion single and double tactile stimulations when their hands were placed in atomic position were tested. Participant's hands were crossed, one over the other, and the tactile stimuli were deliverred either to the hand (beyond the crossing point, Experiment 1) or to the forearm (before the crossing point, Experiment 2). In Experiemnt 3, the left hand was placed in the right hemispace and the right hand in the left hemispace without crossing over (oposite condition).
