Severe left visual neglect has previously been shown to reduce when left hand movements in left hemispace were performed simultaneously to a series of cancellation tasks (Robertson and North, Neuropsychologia 30, 553-563, 1992). The present study demonstrates in two separate cases that this advantage associated with left hand activation was eliminated by simultaneous right hand activation, whether carried out in left or right hemispace. This suggests the existence of an extinction phenomenon for motor output which affects perceptual functioning, and a possible theoretical basis for this is discussed.
先前的研究表明，当在左半空间进行左手运动并同时执行一系列删除任务时，严重的左侧视觉忽视症状会减轻（罗伯逊和诺思，《神经心理学》30卷，553 - 563页，1992年）。本研究在两个独立案例中证明，无论右手运动是在左半空间还是右半空间进行，同时进行右手运动都会消除与左手激活相关的这一优势。这表明存在一种影响感知功能的运动输出消退现象，并对此进行了可能的理论基础探讨。
