The preference for color or form as bases for similarity judgments among preschoolers (ages 2-5) and its relationship to the differentiation of form and color concepts as indexed by discrimination, identification, and labeling were investigated. (SB)

The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fourth graders. Results supported the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. (Author/DB)

This study compared the use of discrete and relational aspects of visual configurations in making similarity judgments. Subjects were 3-, 4-, 5-, and 8-year-old children and adults. (BD)

Infants of five, seven, and nine months were shown two video images on monitors placed side by side. Images were accompanied by a soundtrack that matched one of the images. Results indicated that age-related changes in infants' coordination of auditory and visual depth information took place between the ages of five and nine months. (SH)

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…

The main purpose of this study was to investigate whether children's perceptual comprehension of symmetrical numerical displays was greater than their comprehension of asymmetrical numerical displays. Effects of sex, age and socioeconomic status were looked at. Seventy-three kindergarten and first grade children participated in the study.…
