Over forty years have passed since the first evidence showing the unbalanced attentional allocation of humans across the two visual fields, and since then, a wealth of behavioral, neurophysiological, and clinical data increasingly showed a right hemisphere dominance for orienting of attention. However, inconsistent evidence exists regarding the right-hemisphere dominance for executive control of attention, possibly due to a lack of consideration of its dynamics with the alerting and orienting functions. In this study, we used a version of the Attentional Network Test with lateralized presentation of the stimuli to the left visual field (processed by the right hemisphere, RH) and right visual field (processed by the left hemisphere, LH) to examine visual field differences in executive control of attention under alerting and orienting of attention. Analyses of behavioral performance (reaction time and error rate) showed a more efficient executive control (reduced conflict effect) in the RH compared to the LH for the reaction time, under conditions of increased alerting and of informative spatial orienting. These results demonstrate the right-hemisphere superiority for executive control, and that this effect depends on the involvement of the alerting and orienting functions.

右半球的优势在于对注意力的执行控制。

自从第一个证据显示人类在两个视野中注意力分配的不平衡以来已经过去了40年，从那以后，大量的行为，神经生理学和临床数据越来越显示出右半球在注意力定向方面的主导地位。但是，关于右半球在执行控制注意力方面的优势方面存在不一致的证据，这可能是由于未考虑其具有警报和定向功能的动态所致。在这项研究中，我们使用了注意力网络测试的一个版本，对左侧视野（由右半球，RH处理）和右侧视野（由左半球，LH处理）的刺激进行了侧向呈现。在注意力的警觉和定向下，对注意力的执行控制上的差异。行为表现（反应时间和错误率）的分析表明，在警报时间增加和信息空间定向增加的情况下，与LH相比，RH在RH中更有效的执行控制（减少的冲突效应）。这些结果证明了右半球在执行控制方面的优势，并且这种效果取决于警报和定向功能的参与。
