Abstract(in Japanese) (See Japanese page)
Abstract(in English) The ability of humans to separately attend either color or motion was investigated using psychophysical techniques. One thousand random dots were presented as visual stimuli in an imaginary circular patch. The target was defined by nineteen colors including one of two target colors (red/green) and random motions including one of two coherent motions (expansion/contraction). Subjects were asked to judge either the target color or the target motion. The reaction times (RTs) and the error rates (ERs) to the subject's responses were recorded under two conditions: (1) when an irrelevant dimension was kept constant (baseline), and (2) when an irrelevant dimension varied (filtering). Neither RT nor ER differed between the baseline and the filtering conditions (p > 0.8) for either color or motion judgment. Results suggest that humans can attend to either color or motion while ignoring the other dimension.
