Recent investigations have distinguished between ophthalmokinetic and melokinetic factors of unilateral neglect. The aim of our study was to investigate the possible dissociation between melokinetic (premotor) and perceptual factors, avoiding any overt oculokinetic components. We asked four blindfolded left neglect patients to set a dichotic sound in central position, by moving a handle controlling the difference of intensity between the sounds delivered to the left and to the right ears. Two conflicting conditions were used. In the congruent condition, the sound moved in the same direction as the hand movement; in the noncongruent condition, it moved in the opposite direction. One patient performed as if suffering from melokinetic neglect, and another as if suffering from perceptual neglect. The behavior of the other two subjects did not lend itself to a clearcut interpretation.
近期研究已区分出单侧忽视的视动因素和肢体运动因素。我们研究的目的是探究肢体运动（运动前）因素与感知因素之间可能存在的分离，同时避免任何明显的眼动成分。我们让四名蒙眼的左侧忽视患者通过移动一个手柄来控制传递到左耳和右耳声音的强度差异，从而将双耳分听声音置于中心位置。使用了两种冲突条件。在一致条件下，声音与手部运动方向相同；在不一致条件下，声音与手部运动方向相反。一名患者表现得好像患有肢体运动忽视，另一名患者表现得好像患有感知忽视。另外两名受试者的行为难以给出明确的解释。
