Portions of these studies were presented at the 47th Annual Convention of the Western Psychological Association, San Francisco, May 4, 1967.

Accuracy in reporting horizontally arranged letter sequences was measured for second-grade children and for adults using a tachistoscopic single report procedure. Results indicated age differences in both the amount of information encoded out of visual sensory store and in the magnitude of left/right visual field differences. (Author/MP)

Three experiments on tachistoscopic perception of visual stimuli demonstrate that the visual system is sensitive to global topological properties. The results indicate that extraction of global topological properties is a basic factor in perceptual organization. (Author)

In three studies, 12-month-old infants were familiarized either tactually or visually with objects and were then tested for visual recognition memory using either (1) the familiar and a novel object, (2) colored pictures of the objects, or (3) outline drawings of the objects. (Author/MP)

Provides a demonstration of the existence of the McCollough effect in children ages six to nine and tests for any obvious differences in interocular transfer of the effect. (MP)

Results show that infants are not only capable of learning two ill-defined categories, but that they can do so with…
