Spatial localization across channels
article
We have studied vernier acuity for patterns in which the stimuli to be aligned either are similar in their spatial and color characteristics or differ in these properties. The question which we address is whether spatial localization is independent of the channels being stimulated by the patterns to be aligned. We found that the precision of vernier alignment of Gabor patches was very similar irrespective of whether the patches were the same or different in spatial frequency, orientation, or color. It appears that the visual system extracts very precise location information independent of the similarity or dissimilarity of the spatio-chromatic selectivity of the channels carrying that information.
