Abstract

Detection and resolution threshold sensitivity profiles were determined for five target sizes along the horizontal meridian of the central 60° visual field (30° nasal and temporal), utilizing the Tübingen perimeter. In general, increases in stimulus eccentricity and/or decreases in target size produced a decrement in both detection and resolution sensitivities. Magnitude of this effect was much more pronounced for resolution than detection, and the two functions appear to reflect relatively distinct, separate response characteristics. A possible physiological basis underlying the differences between detection and resolution properties is described.
