Visual events are defined by a number of dimensions--their location in space, content (color, shape, etc.), and time tags (onset, duration, etc.). The role of time in infants' performance in the Visual Expectation Paradigm (VExP) was studied to evaluate whether infants encode in their expectation representation the timing of events in addition to…

A total of 45 3-month-olds were observed for stability in forming visual expectations. Findings indicate that infant performance in the Visual Expectation Paradigm is reliable as early as 3 months. Individual differences exist in infants' tendency to form visual expectations. (RH)

The relationship between neonatal visual information-processing and the burst-pause pattern of nonnutritive sucking was explored. (JMB)

This study examined the development of smooth visual tracking in 11 infants 2 and 3 months of age, with particular attention given to the role of expectation in tracking complex visual motion. Data were gathered by recording the image of the infant's eye as he or she tracked a small computer-generated target as it moved in a sinusoidal trajectory…

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

Four studies were conducted to investigate the relation between audition and vision in the human newborn. In all four studies visual activity was recorded with infrared corneal-reflection techniques in 1- to 4-day-old infants. (MS)

Reports research into the visual fixation of 3- to 11-week old infants as they observed adult faces. Reports a dramatic increase in fixations occurred between 5 and 7 weeks for all conditions. (SL)

The effects of perceptual and cognitive factors on information processing in visual periphery were studied in 5- and 8-year-old children and in adults. Subjects judged either the similarity (Study 1) or identity (Study 2) of geometric forms. (Author/SB)

Focuses on investigations of infant sensation and perception over the past 25 years. Describes the knowledge base concerning the sensory and perceptual world of the infant in the mid-1960s. Methodological highlights in the study of vision and audition are covered. (RJC)

This study investigated the possibility of a functional relation between the auditory and visual systems in the human newborn beyond reflexive organization. Visual activity was monitored in 16 newborns through the use of infrared corneal reflection video tape recording. Infants were observed in total darkness and while monocularly viewing a…

Infants' visual fixations were monitored while they viewed predictable and unpredictable sequences of stimuli. Analyses of anticipatory fixations indicated that by two months of age, infants form expectations for the reappearance of visual stimuli positioned opposite to each other. By three months, infants rapidly form expectations for asymmetric…

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…
