Spatial integration in human vision with bichromatically-mixed adaptation field.
The present study showed that the spatial integration area was expanded even if the background energy was increased, provided that the background consisted of the two colors which were opponent to each other (red/green). This expansion was not found for the subjects with dichromatic color vision even though the same condition was utilized. It was suggested that polarization and its release (the change of adaptation level) of the chromatically-opponent red/green system were involved in control of spatial integration area.
