A memorized target is often mislocalized towards a task-irrelevant landmark (the landmark effect). By using Kanizsa subjective figures as a landmark we have shown that attentional shifts towards an illusory object result in the landmark effect (Experiment 1). The observers manually reproduced the position of a target circle which was presented above a central fixation cross accompanied by a physical or subjective square. As a result, the degree of the memory displacement towards illusory squares was comparable with that towards physical squares. This result indicated that a coarse spatial filtering cannot explain the landmark effect. In addition, we confirmed the landmark effect in object- and location-based attention paradigms (Experiments 2 and 3). Given the results, we suggest that attentional modulation of neural location signals might be the source of the displacement.
