The end positions of eye and hand movements were both drawn towards a distracter that was presented nearby the target. They thus showed a so-called global effect. In contrast, perception was not influenced by the presence of a distracter. These results are discussed with regard to the question whether eye, hand, and perception are based on shared or separate target representations and readout triggers. We conclude that separate representations and readout triggers for eye and hand are the most likely case.
眼睛和手部动作的最终位置都被吸引到目标附近呈现的干扰物上。因此,它们表现出一种所谓的全局效应。相比之下,知觉不受干扰物存在的影响。我们针对眼睛、手部动作和知觉是基于共享的还是独立的目标表征及读出触发因素这一问题对这些结果进行了讨论。我们得出结论,眼睛和手部动作最有可能具有独立的表征和读出触发因素。
