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

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…

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)

Three experiments tested the hypothesis that the differences in infants' time of looking at a stimulus are due to infants' differential sensitivity to global and local visual information. Found that both long- and short-looking four-month-old infants were sensitive to both types of information. These results do not support the hypothesis. (MDM)

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)

The article examines evidence of visual impairment caused by excessive amounts of ultraviolet (UV) light. Among considerations when using a source of UV light for vision stimulation are the position of the child and teacher, use of window glass filters or protective glasses, and careful recordkeeping of all UV stimulation. (Author/JW)[

A new theory linking information extraction patterns to the visual perception of direction and extent is presented. Seven demonstration experiments employ predictions from efferent considerations to create a new set of illusions of direction and extent and to demonstrate new predictable variations in the magnitude of some classical illusion…

Results support the contention that infant attention should be divided into separate attention-getting and attention-holding processes. (Author)

The hypothesis was that the two hemispheres have different functions in normal vision, the dominant one analyzing the "figure," and the nondominant the "background." The investigation examined responses of 41 female psychology students. Results were consistent with the hypothesis. (Author/RD)

The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

Four experiments tested four month olds on visual discrimination tasks. As the time allotted to solve these problems was shortened, infants who looked at stimuli for a short amount of time performed better than other infants, indicating that performance superiority was attributable to speed of processing.
