Abstract
The behavior of preschoolers in two sighting tasks was observed. In one task, the child was asked to sight a target through a tube, and, in the other, to point to a target. In addition to monocular sighting, the “cyclops effect” was observed; the child positioned the tube or finger in line with the target and a point between the eyes and left it there. Observation of both types of response suggests a developmental shift from central sighting, which reflects the visual direction basis of sighting tasks, to monocular sighting, which reflects the monocular alignment required by the tasks.
