The capacity of newborn infants for smooth-pursuit eye movements in single-target tracking and in optokinetic nystagmus to a moving striped field was examined utilizing DC electrooculography. (JMB)

Attempts to differentiate the serial habituation hypothesis from the regression to the mean hypothesis as explanations for the reduction of visual fixations in the form perception of four-month-old infants. Results support a regression to the mean interpretation of the data. (JMB)

The thesis of this article is that, in the drawings of very young children, line is produced as a path before it is produced as a boundary. An explanation for this progression is proposed. (Author/JMB)

In three studies of infants' ability to perceive partially occluded objects with specific appearances, a screen alternately uncovered and covered either a connected or interrupted rectangle. Pattern of infants' looking times suggests that they perceive the unity of the partially occluded object by 6.5 months but did not perceive the form of the…

Assessed infants' and adults' adjustment of hand orientation before grasping objects. Found that infants modified their hand orientation to match the long axis of an object, did not make anticipatory hand adjustments before reaching through a narrow aperture to grasp an object, and oriented their hand to be parallel with the handle of an object.…

This investigation examined whether infants display "boundary extension"--a tendency to remember more of a visual scene than was presented. Three- to 7-month-olds were familiarized with a photograph of a visual scene, and tested with wide-angle versus close-up views of the scene. Infants preferred the close-up, indicating that they perceived the…

Children of ages two and one-half, three, and three and one-half years were tested for their understanding of object hiding. Results indicated that children of this age can be both nonegocentric and skillful at estimating what other people do and do not see under various viewing conditions. (JMB)

Measures of visual information processing in dyslexic and normal children were compared. Significant differences were found between dyslexics and normals at early stages of visual information processing. (ST)

Examines the ability of infants ranging in age from 21 to 44 hours old to discriminate among visual stimulus arrays. Infants were able to discriminate between small sets of dots (two to three dots) but not between larger sets (four to six). (Author/MP)

Examined acuity thresholds for 1- and 2-month-old infants by presenting square wave gratings in a preference paradigm at four viewing distances. (Author/JMB)

Four studies explored preschoolers' understanding of thought bubbles depicted in cartoons. Few three- and four-year olds knew what a thought-bubble depiction was without instruction, but if simply told that the thought bubble "shows what someone is thinking," the majority easily understood the devices as depicting thoughts generally and…

Assessed 14-week-olds' attention to green or red target objects moving in a field of distracting objects that varied in color. Found that infants' detection of green moving targets was masked in the presence of mixed red and green objects. Masking was not observed for red targets or for green targets in a field of green objects. (BC)

Preschoolers placed stickers on maps to show locations of objects currently in view. Vantage point (eye-level versus raised), map form (plan versus oblique), and item type (floor versus furniture location) were varied. Results showed that using an oblique map first aided subsequent performance on a plan map. Subjects performed worse on floor…

This study is an initial investigation of the effects of a fading procedure upon acquisition and transfer of discrimination learning with children younger than 36 months of age. (CS)
