    Abstract

    The cumulative probability of target discovery during search has been related experimentally to the relevant "conspicuity area", the visual field in which the target can be discovered after a single eye fixation. During search, "non-targets" were found to be fixated spontaneously in proportion to their conspicuity area. Further small spontaneous eye fluctuations are described that occurred, during determination of the conspicuity areas, in the direction of the target discovered. Their occurrence and delay depended on the target eccentricity and the size of the conspicuity area. The results emphasize the relevance of the conspicuity area to research on visual selection.
