We asked 12 right-brain-damaged patients (6 with left neglect signs and 6 without left neglect signs) to perform a straight ahead pointing task and a visual detection task with lateralized motor response, in order to investigate the relationship between the position of the egocentric reference and response time and accuracy in producing lateralized arm movements. Results showed that there was no correlation between the position of the egocentric reference and neglect signs, nor between the position of the egocentric reference and the latencies to direct a motor response toward either side of space. These findings were interpreted within the context of egocentric hypotheses of neglect. In particular, it was suggested that attentional or intentional neglect signs cannot be considered as a direct consequence of an ipsilesional deviation of the egocentric reference.
我们让12名右脑损伤患者（6名有左侧忽视症状，6名无左侧忽视症状）执行向前直线指向任务和带有侧化运动反应的视觉检测任务，以研究自我中心参照位置与产生侧化手臂运动时的反应时间及准确性之间的关系。结果显示，自我中心参照位置与忽视症状之间没有相关性，自我中心参照位置与向空间任一侧做出运动反应的潜伏期之间也没有相关性。这些发现是在忽视的自我中心假说背景下进行解释的。特别是，有人提出，注意力或意向性忽视症状不能被视为自我中心参照向患侧偏移的直接后果。
