在目标导向的眼睛和手运动之前的注意转移被认为是运动目标选择的标志。在眼手同步运动过程中，效应器是否会竞争一个共享的注意资源，或者注意资源是否可以独立地分配给多个目标位置，这是一个有争议的问题。视空间注意平行分配给扫视和伸达目标的独立的、特异效应器的目标选择机制可以预测整体注意能力随着活跃效应器数量的增加而增加。我们在一个修正的视觉注意理论（TVA; Bundesen, 1990）范式中检验了这一假设。参与者报告了在眼睛、手或眼手联合运动准备过程中向中央提示位置简要呈现字母的情况。根据TVA对数据进行建模，使我们能够评估整体注意力能力和视觉注意力在视觉工作空间中单个位置的部署。在两个实验中，我们发现注意力主要被分配到运动目标上——效应器之间没有明显的竞争。然而，在眼和手目标上的平行好处在非运动位置上也有相应的代价，并且两种效应系统的同时使用并不能增加整体的注意能力。此外，运动前的注意力转移在加工资源的自愿配置中占主导地位，导致自愿注意分配严重受损。我们的结论是，由于足够的加工资源可以从运动无关的位置撤回，注意力转移到多个效应目标而没有相互竞争。
Attention shifts that precede goal-directed eye and hand movements are regarded as markers of motor target selection. Whether effectors compete for a single, shared attentional resource during simultaneous eye-hand movements or whether attentional resources can be allocated independently towards multiple target locations is controversially debated. Independent, effector-specific target selection mechanisms underlying parallel allocation of visuospatial attention to saccade and reach targets would predict an increase of the overall attention capacity with the number of active effectors. We test this hypothesis in a modified Theory of Visual Attention (TVA; Bundesen, 1990) paradigm. Participants reported briefly presented letters during eye, hand, or combined eye-hand movement preparation to centrally cued locations. Modeling the data according to TVA allowed us to assess both the overall attention capacity and the deployment of visual attention to individual locations in the visual work space. In two experiments, we show that attention is predominantly allocated to the motor targets – without pronounced competition between effectors. The parallel benefits at eye and hand targets, however, have concomitant costs at non-motor locations, and the overall attention capacity does not increase by the simultaneous recruitment of both effector systems. Moreover, premotor shifts of attention dominate over voluntary deployment of processing resources, yielding severe impairments of voluntary attention allocation. We conclude that attention shifts to multiple effector targets without mutual competition given that sufficient processing resources can be withdrawn from movement-irrelevant locations.
