EGOCENTRIC REFERENCE AND SPACE ORGANIZATION IN 30 NORMAL SUBJECTS ANDONE UNILATERAL NEGLECT PATIENT

Thirty normal subjects and one neglect patient were submitted to a str aight-ahead pointing task in three conditions: head and trunk aligned at 00, and trunk rotated 150 to the left or to the right relative to t he head. This experiment was conducted to ascertain the presence of an ipsilesional deviation of the egocentric reference among the neglect patient, consecutive to the right parietal lesion and to study the eff ect of the trunk position on this reference. We confirm that the refer ence is ipsilesionally deviated in neglect patients, and that the trun k orientation determines the position of this reference.
