Compares one study in which 5-year-olds and another in which adults quantified random patterns of dots under unlimited exposure duration. Data on operating ranges and rates for subitizing and counting are included. (JMB)

Eye movement and fixation responses of three- to six-year-old children and adults were recorded during a pattern recognition task. The results suggest that visual fixations do not always reflect active attention, and that direct fixations of visual information are clearly not sufficient and may not be necessary for problem solving.

Incentives produced no discernible effect upon the performance of either of two treatment groups. The data were also analyzed for latency of response, practice effects and reversal errors, none of which was related to reading retardation. (WY)

Presents two experiments which investigated whether there is a shift with age in the relative speed and difficulty of same versus different judgments. Subjects included preschoolers, third graders, and college students. (SDH)

Results from three studies involving college, third grade, and kindergarten subjects, suggest that individuals across a wide age range are able to use the visual properties of a stimulus for only a very brief period as the basis for making matched judgments. (Author/SDH)

A recall paradigm tested twenty-four 5-year-olds and twenty-four adults on short-term recognition memory for briefly presented visual information. Results indicate that processes other than verbal labeling are probably more responsible for age differences in immediate memory performance than labeling. (JH)

Three experiments were conducted to examine whether infants can detect the color of stationary and moving objects and maintain this discrimination over change in velocity. Subjects were 80 infants ages 8 to 20 weeks. (MP)

Three experiments evaluated color specificity knowledge and related semantic effects on recognition memory. (Author/SB)

Investigated the influence of vertical, horizontal, and diagonal symmetry on recognition memory in preschool, kindergarten, and second-grade children. The influence of contour was also investigated. Children were trained to attend to axes of symmetry in order to improve performance on a memory task. (Author/DB)

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classifications of younger and older subjects. Results support a differential-sensitivity view of perceptual development which asserts that individuals at all ages primarily perceive and use separate relations. (RWB)
