We review all 14 extant studies of covert visuospatial attention in attention deficit hyperactivity disorder (ADHD) (total N=248). Metaanalysis showed that intriguing but isolated findings of alerting or posterior disengage deficits were too small to reliably detect with the sample sizes typically employed. Posterior move and engage operations and the vigilance sustained attention process were normal in ADHD. For exogenous cues, effect sizes for group differences were homogeneously small across all repeated-measures conditions, as were calculations of cost, benefit, and validity effects. For endogenous cues, effect sizes were heterogeneous; however, calculations of cost, benefit, and validity effects were small and homogenous. The most parsimonious conclusion may be that ADHD is not characterized by significant visual orienting dysfunction, but questions remain about the extent of anterior lateralized effects in the combined subtype and about attentional functioning in the inattentive subtype.

在注意缺陷多动障碍中寻找注意缺陷：视觉空间定向的情况。

我们回顾了在注意力缺陷多动障碍（ADHD）（总N = 248）中隐性视觉空间注意力的所有14个现有研究。荟萃分析显示，令人警觉但孤立的警报或后脱离缺陷不足的发现太小，无法用通常使用的样本量可靠地检测出来。在多动症中，后移和接合操作以及保持警惕的持续注意力过程是正常的。对于外源线索，在所有重复测量条件下，群体差异的影响大小均很小，成本，收益和效用计算也是如此。对于内源性线索，效果大小是异类的；但是，成本，收益和效用的计算量很小且同质。最简约的结论可能是ADHD没有明显的视觉定向功能障碍，
