Comparison of Rhesus and Human Spectral Dynamic Visual Acuity.
Abstract
The visual acuity of humans and rhesus monkeys is quite comparable for stationary targets. However, in many situations visual acuity is required for targets that are moving rather than stationary. In this experiment, we have measured the dynamic visual acuity function for the rhesus and compared it with the dynamic visual acuity for the human. For targets that are achromatic, the rhesus and human are quite comparable, although the Rhesus seems to have somewhat better acuity for targets that are moving at the upper velocity extremes. When measurements were made with chromatic targets, however, certain differences appeared across species. In the short end of the spectrum, the blue region, the rhesus is somewhat superior in its acuity for high velocity targets; in the long end of the visible spectrum, the rhesus appears somewhat weaker in its ability to resolve rapidly moving targets. These differences are not inconsistent with recent observations of spectral differences between human and rhesus reported for static acuity measurements. (Author)
