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…

This study investigated: (1) whether infants can develop expectations for events that alternate along the vertical axis; and (2) whether infants who form expectations with one action set can transfer them to a different action set--that is, from vertical to horizontal eye movements. A total of 32 infants of 3 months of age saw one of two picture…

Adults and children used similar report strategies in a tachistoscopic memory task, but the capacity of the children's short term memory was strikingly limited. Portions of this paper were read at the Eastern Psychological Meetings, Washington, D.C., April, 1968. (MH)

Findings indicate that infants can detect regularity in spatiotemporal series; will develop expectancies for events in the series; and will act on the basis of those expectancies even when their actions have no effect on the stimulus events. (PCB)

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)

Examined organization of 5.5, 8.5, and 11.5-month-olds' reaching skill for stationary and moving targets. Found that infants of all ages made anticipatory adjustments of hand alignment; effectiveness of these adjustments improved with age. Regardless of age, infants used dynamic information from spinning and oscillating targets to update ongoing…

A recall paradigm tested twenty-four 5-year-olds and twenty-four adults on short-term recognition memory for briefly presented visual information. Results indicate that processes other than verbal labeling are probably more responsible for age differences in immediate memory performance than labeling. (JH)

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…
