Evaluates models of infant visual preferences with predictions based on the physical attributes of visual patterns using pairs of schematic faces and abstract patterns identical except for contrast reversals. Results suggest that a fundamental change in the determinants of visual preference occurs postnatally between 6 and 12 weeks. (Author/RWB)

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)

Vision is a complex process involving three phases: physical (acuity), physiological (integrative), and psychological (perceptual). Although these phases cannot be considered discrete, they provide the basis for the visual screening procedure used by the Reading Services of Colorado State University and described in this document. Ten tests are…

Statistically significant correlations of .37 and .57 were obtained between infant recognition memory scores obtained at four to seven months and later vocabulary tests of intelligence, for 54 children tested at four and for 39 children seen at seven years, respectively. Obtained values did not vary by sex. (Author/RD)

Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane.

Examined the stability of two aspects of infant visual attention derived from the paired-comparison procedure in infants tested at 6, 7, and 8 months of age. The two aspects were novelty preference and exposure time. Suggests that both novelty and exposure-time scores reflect moderately stable but independent characteristics of infant behavior.…

Forty five-year-olds compared two arms of an L-shaped figure on-axis or perpendicular to axis inside circles of different diameters. In making perceptual judgments about the relative length, the children tended to describe the on-axis line as longer. The context model of visual anomalies was supported. (Author/CM)

Previous studies have found that an object can be categorized faster at a basic level (hammer) than at either a subordinate (club hammer) or a superordinate level (tool). While some attribute this result to basic categories having more distinctive attributes, other factors might cause this result. For example, basic categories routinely have…

For the age range tested there is a lag between the perception and production of certain facial expressions. (Authors)

This study examined 2- to 3-year-olds' ability to make a pretend-real distinction in the absence of content cues. Children watched two actors side by side. One was really eating, and the other was pretending to eat, but in neither case was information about content available. Following the displays, children were asked to retrieve the real food…

This study examines the effects of three levels of visual complexity upon the learning of an instructional slide tape program about the functions of a human heart. The three levels of complexity were a simple line drawing in color, an illustration in color, and a realistic color photograph. The effects of visual stimulus complexity upon…

This inventory is designed to assess the degree to which adults who are illiterate possess some of the more commonly acknowledged requisites to learning to read. Instructions for administering the inventory are provided in enough detail to insure a reasonably accurate assessment of visual discrimination and select cognitive abilities. The…

Reading achievement tests have been used to identify deficiencies in inner city, poor readers; however, they often do not provide information about encoding strategies which lead some children to academic success. Immediate memory and visual analytic differences which contribute to the success of skilled readers are isolated in this study using 20…

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…
