Reports three experiments in infant visual perception which studied the processes underlying infants' shifts of fixation from one object to another. (JMB)

Three experiments investigated the dynamics of human infant visual fixation. Results showed that, over a series of trials, four-month-olds fixate longer on a complex than on a simple stimulus. Findings challenge prevailing cognitive-schema theories as a complete account of the dynamics of infant visual fixation. A two-process theory that accounts…

Based on an M.A. degree submitted to McMaster University, England.

Thirty-two three-month-old infants participated in two experiments showing color videotapes of facial stimuli in a paired comparison format. Suggests that contrast in effect of eye contact availability and rather subtle stimulus motion (blinking) implies that three-month-old infants are comparatively insensitive to being the object of another's…

Human neonates selectively fixated patterns with curved rather than straight contours when the outermost contours differed in this form variable and when quantitative variables were controlled. Data indicated the presence from birth of a discrimination ability basic to later form perception. (Author/ED)

Based on PhD thesis submitted to Brown University (June 1967).

Infants of one, two and three months of age were presented with two checkerboard patterns, one stationary and the other moving in a horizontal oscillatory motion at one of eight rates. Results showed reliable differences in ocular behavior as a function of rate stimulus motion for all three groups of infants. (MS)

Individual differences in pattern of habituation in fixation time and cardiac change to visual and auditory stimuli are described. Subjects were 94 5- and 10-month-old infants. (Author/MP)

Visual pattern preferences were established for 96 9- and 13-week-old infants using stimuli varying in contour density presented either at a low, moderate, or high luminance level. Age differences in the maximally preferred patterns across stimuli and luminance levels indicated that luminance interacts with contour density in determining stimulus…

This experiment examined developmental changes in the ability of infants to learn conceptual categories regarding the human face. A total of 108 infants, aged 18, 24, and 30 weeks, were habituated to (1) the same face in the same orientation, (2) the same face in differing orientations, or (3) different faces in different orientations. All…

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)
