| Abstract(in English) | Figure-ground segregation plays a crucial role in the process of object recognition. The segregation is modulated by spatial attention as well known in ambiguous figures. We investigated whether feature-based attention modulates the perception of figure direction. Specifically, we carried out psychophysical experiments with ambiguous figures that consist of dynamic random dot patterns in order to examine whether the perception of figure direction is modulated if attention is applied to the specific motion direction that constitute a dot pattern. The result showed that a region with the attended motion direction is more frequently perceived as figure, indicating that feature-based attention modulates the human perception of figure-ground segregation. |
