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)

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

Examined newborns' visual detection of peripheral and central stimuli. (BD)

Five-month-old infants were habituated to three types of visually presented rigid motion, with duration of fixation as the dependent measure. After reaching a criterion of habituation, a fourth rigid motion (not habituated) and a deformation were presented. (Author/SS)

A study explored the phenomenon of space constancy or visual stability of stimulus patterns across saccades (a series of small jerky movements of the eye) by making changes in natural, full-color pictures during selected saccades as observers (18 members of the University of Illinois community) examined them for 20 seconds in preparation for a…

This paper presents a model of infant visual recognition which proposes that an infant faced with a novel and a previously exposed target responds with one "look" consisting of a chain of 2 covert responses: (1) an attentional observing response to a dimension and (2) a fixation response to a cue. (Author/JMB)

At some time during every fixation a decision is made to move the eyes, directing them to a new location in the stimulus array. To understand the eye movement control processes, three general hypotheses concerning the cognitive basis for deciding to move the eyes were investigated: the saccade (movement) initiation time is determined only on the…

Two studies: (1) assessed the infant's ability to perceive differences between two-dimensional and three-dimensional stimuli; and (2) tested the infants' ability to transfer responses across dimensions. (Author/SB)

Examined length of fixation time responses of neonates to pairs of red, blue, and green acetate stimuli. (Author)
