Schizophrenic subjects have defects in oculomotor control which appear to be the result of inefficient processing of sensory information, not a problem in controlling the movement itself [Mather and Putchat (1983b) J. Psychiat Res. 17, 343-360]. A demonstration that manipulating sensory information by removing context information alters these same saccadic eye movements in normals is the subject of the present research. Without context information (in the dark) people make more double-jump saccades and overshoot a target, as schizophrenics do usually. Normals have a reduced number of double saccades, a different pattern of eye movement, when the target itself is not visible. These findings reinforce the suggestions that schizophrenics, despite their normal oculomotor reaction time, are less effective than normal subjects at processing the spatial information which guides their eye movement.
精神分裂症患者存在眼球运动控制缺陷，这似乎是感觉信息处理效率低下的结果，而非运动控制本身的问题[马瑟和普查特（1983b）《精神病学研究杂志》17，343 - 360]。本研究的主题是证明，通过去除背景信息来操纵感觉信息，会改变正常人的这些相同的扫视眼动。在没有背景信息的情况下（在黑暗中），人们会像精神分裂症患者通常那样，做出更多的双跳扫视并越过目标。当目标本身不可见时，正常人的双扫视次数减少，眼动模式也不同。这些发现强化了以下观点：尽管精神分裂症患者的眼球运动反应时间正常，但在处理引导其眼动的空间信息方面，他们比正常人效率更低。
