Implications of distracter effects for the organization of eye movements, hand movements, and perception.
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.
