We studied spatial attentional performance on a visually cued reaction time task in men with isolated hypogonadotropic hypogonadism. A subset of these patients, who displayed mirror movements, have spatial attentional abnormalities. They were slow to respond to targets in the right visual field and especially slow when those targets followed incorrect or diffuse cues. This slowing was present for at least 500 msec after cue onset. They responded equally to targets in the left visual field independent of the spatial cues. The patient population as a whole was significantly faster than controls across all experimental conditions, although the speed of their attentional movement was normal. These data suggest that patients with isolated hypogonadotropic hypogonadism perform reaction time tasks quickly, that faster reaction times do not reflect superior attentional performance, and that a subset of these patients has a spatial attentional abnormality.
我们研究了患有孤立性促性腺激素缺乏性性腺功能减退症男性在视觉线索反应时任务中的空间注意力表现。这些患者中有一部分表现出镜像运动，存在空间注意力异常。他们对右侧视野中的目标反应较慢，尤其是当这些目标跟随不正确或分散的线索时反应特别慢。线索出现后至少500毫秒这种反应迟缓都存在。他们对左侧视野中的目标反应相同，与空间线索无关。尽管他们注意力移动的速度正常，但在所有实验条件下，整个患者群体的反应速度都明显快于对照组。这些数据表明，患有孤立性促性腺激素缺乏性性腺功能减退症的患者完成反应时任务速度很快，更快的反应时间并不反映出更好的注意力表现，并且这些患者中有一部分存在空间注意力异常。
