Describes an experiment in which the rate of habituation of fixation of 12-week-old infants to a homogeneous stimulus series where a cube was presented in different orientations was contrasted with the rates of habituation to various heterogeneous series where a cube was alternated with some other solid.

Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or…

Two experiments compared responses of 5-month-old infants to a live person, the person's photograph, photographs of dissimilar persons, and photographs of similar persons. Results indicated that infants use gross physiognomic features to perceive similarity between live persons and their photographs. (Author/JMB)

Two-month-old infants were examined to determine whether, during localization of peripheral target, step size and number of steps were determined prior to the first saccade in a localizing series. It was found that on the majority of trials, a series of saccades was made toward the target hemifield. (Author/RH)

Tested and confirmed, in three experiments, the hypothesis that children's interpretation of pictorial conventions and of the expression "look like" may increase their tendency toward intellectual realism. That is, a tendency to respond to requests for perceptual reports by indicating what is known about an object or array, rather than…

Investigated 5-month-olds' perception of an object whose center was occluded and whose ends were visible only in succession. Found that infants perceived the object as one connected whole when the ends underwent common motion but not when the ends were stationary. Results suggest that infants perceive object unity but not object form. (Author/BC)

Two experiments with 18-week-old infants employed an interference paradigm to study infant visual memory for faces. (Author/JMB)

In these two studies, neonatal oculomotor behavior was observed under various conditions of visual and auditory stimulation. Findings showed auditory and visual perception to be relatively independent during the neonatal period. (Author/JMB)

A total of 20 infants either five or seven months of age viewed computer-generated random-lot displays in which accretion and deletion of texture provided the only information for contours. Infants of both age groups showed significant preferences to reach for the apparently nearer regions in the displays. (Author/RH)

A multiple habituation paradigm was used to determine whether 10- to 12-month-old infants were able to discriminate between visual arrays differing only in their numerosity. (Author/RH)

Four experiments were conducted to investigate the development of visual accommodation in one- to three-month-old infants. Accommodation responses and pupil diameters were measured at various stimulus distances. Results suggest that changes in depth of focus in the first three months are largely responsible for growth in accommodation. (Author/SS)

One- to four-month-old infants' abilities to see various structural characteristics of a subjective contour figure were assessed by means of a habituation procedure. (Author/DB)
