This investigation was focused on identification of various limits of human spatial discrimination, two-dimensional sampling properties of the retinal photoreceptor lattice, and the consequences for spatial vision. Highlights from this study are briefly listed. 1) Foveal Spatial Discriminations are hyperacuity tasks; 2) The spatial-frequency discrimination function (delta f/f vs f) is segmented; 3) The discrimination segments can be related to retinal sampling; 4) Scaling mechanisms apply to low resolution tasks; 5) The photoreceptor lattice is a highly ordered hexagonal array; 6) A hexagonal component exists in spatial discrimination; 7) A new 'metric' model of spatial vision is based on visual sampling.

The three specific aims of this current ongoing project include: 1) the characterization of the human and monkey photoreceptor lattice; 2) the study of new spatial discriminations in two-dimensions including circle center, area, and dot density discriminations, and 3) the expansion and generalization of current models of one-dimensional spatial discriminations such as spatial-frequency, line separation, and vernier acuity.

Comparative Color Vision provides information about the means by which color vision has been studied in nonhuman animals and about the outcomes of these studies for a variety of representative species. Individuals who become interested in color vision in animals come from a variety of different educational backgrounds—from the traditional biological and behavioral sciences as well as from more applied fields. Accordingly, this book includes sufficient tutorial information about color vision so that a relative newcomer would be able to make sense out of this area without having to search out still more background material. To provide this, basic information about the psychophysics of color vision and about the methods used to study color vision in animals is presented; along with coverage of the broad range of biological mechanisms responsible for color vision. Subsequent chapters present systematic reviews of studies of color vision in a wide selection of vertebrate species. The final chapter is devoted to a discussion of two fascinating issues raised by studies of animal color vision: the evolutionary origins and the functional utility of color vision.
