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

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)

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 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.

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

Discusses the effects on oculomotor behavior of variations of the physical attributes of text and similar effects from physical word cues processed in the reader's parafoveal vision. (HOD)

Compares estimates of monocular visual resolution of children 6- to 36-months of age with three psychophysical procedures: the Probabilistic Estimation by Sequential Testing (PEST), a modification of the PEST procedure, and the method-of-constant stimuli. (HOD)

The functions of spaces between words in adult reading of text were investigated in three experiments. Results were consistent with a two-process theory in which filling parafoveal spaces disrupts guidance of the next eye movement and filling foveal spaces disrupts processing of the fixated word as well.

THE VARIOUS PROCESSES AND CONTROLS INVOLVED IN THE VARIATION OF EYE MOVEMENTS ACCORDING TO READING MATERIAL ARE DISCUSSED. RELEVANT RESEARCH LITERATURE IS CITED, AND AREAS REQUIRING ADDITIONAL RESEARCH ARE OUTLINED. LANGUAGE TEXT CONTROL AND THE CENTRAL NERVOUS SYSTEM AS POSSIBLE LOCI OF CONTROL FOR EYE MOVEMENTS ARE EXPLORED. EVIDENCE SUPPORTING…

Investigates the dominance of global versus local visual properties in four-month-old infants as a function of individual differences in fixation duration. Suggests that long-looking infants process visual information more slowly than short-looking infants, and there may be qualitative differences in the manner in which the two groups of infants…

Pioneering research has shown that infants are capable of perceptual discrimination and has provided some indication of the nature of the discrimination; that is, what stimuli are differentiable. Studies have demonstrated that significant effects exist, in stimulus-pair comparisons, for age of infant, speed of movement of stimulus during…
