Van der Kamp and Masters (2008) reported that goalkeeper postures that mimic the Müller-Lyer (1889) illusion affect the location of handball penalty throws. In four experiments, we aimed to verify that the effects on throwing are consistent with an illusory bias (Experiments 1 and 2), and to examine how these observations can be understood in the context of Milner and Goodale's (1995, 2008) two-visual systems model (Experiments 3 and 4). Experiments 1 and 2 confirmed that the goalkeeper Müller-Lyer posture may indeed induce an illusory bias in throwing, implying that allocentric information is used in far-aiming action tasks. Experiment 3 demonstrated that the bias was not related to a participant's throwing skill. Experiment 4 suggested that an absence of visual information to instantaneously specify target location may have induced use of context-dependent allocentric information, causing the throwing bias. The results are discussed in the context of recent debates about the roles of the two-visual systems in perception and action. It is suggested that the two systems are first and foremost perceptual systems that serve the pickup of different sources of information.
范德坎普和马斯特斯（2008年）报告称，模仿缪勒-莱尔（1889年）错觉的守门员姿势会影响手球罚球的位置。在四项实验中，我们旨在验证对投掷的影响与错觉偏差一致（实验1和2），并研究如何在米尔纳和古德尔（1995年、2008年）的双视觉系统模型背景下理解这些观察结果（实验3和4）。实验1和2证实，守门员的缪勒-莱尔姿势确实可能在投掷中诱发错觉偏差，这意味着在远距离瞄准动作任务中使用了以自我为中心的信息。实验3表明，这种偏差与参与者的投掷技能无关。实验4表明，缺乏即时指定目标位置的视觉信息可能导致使用依赖于上下文的以自我为中心的信息，从而造成投掷偏差。我们将在近期关于双视觉系统在感知和行动中作用的辩论背景下讨论这些结果。有人认为，这两个系统首先是为获取不同信息源服务的感知系统。
