The ability of 3-, 4-, and 5-year-old children to infer the position of an object in a room from information contained on a map was assessed under five conditions: (1) map aligned inside the room (the pretest); (2) map aligned outside the room; (3) map rotated 180 degrees inside the room; (4) map rotated 180 degrees outside the room; (5) map held…

Changes in the perception of figural aftereffects occurring during adulthood were investigated with 56 female subjects. A significant linear trend analysis indicated that the magnitude of the figural aftereffects increased very slightly with age. This was supported by a significant T value which suggested a difference between the two extreme age…

This study attempted to investigate the effects of school experience on visual perception tests involving line figures and forms. There were two experiments in this study. Experiment 1 examined the independent and interactive influences of school experience and chronological age in kindergarten children. Experiment 2 compared the effects of…

Reports two experiments which examined developmental changes in the patterns of preference for varying degrees of perspective while controlling for the station point used in viewing. Subjects were 28 preschool children (age four years), 23 elementary school students (age six years) and 30 college students from introductory psychology classes. (MP)

Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

A visual search task was used to assess developmental changes in elementary school children's selective attention to specified portions of a visual display. (Author/SB)

Describes two studies that demonstrate young children's perception of color materials differs from that of adults in two ways: (1) the stimulus dimensions of hue, chroma, and value appear to result in somewhat more separable perception for young children than for adults, and (2) the perceived similarities the color materials are not the same for…

Preschool and third grade children matched the orientation of stimuli tachistoscopically presented at times individually set to achieve about 75 percent correct performance. Preschoolers showed no superiority on left versus right while third graders showed significant top and right superiorities. Results are compared with those for adults on the…

Studied influences of simultaneously and successively exposing kindergarten and elementary children to low and high speed motion pictures on their judgment of distance, synchroneity, and isochronism. Concluded the presence of tau and kappa-movement effects in the younger group and anti-kappa effects among the older group. (CC)

The study tested the existence of communication between visual and haptic senses with 3- and 5-year-old children. Major finding: only visual-haptic training improved performance on the haptic indentification test. Apparently there was no transfer across sense modalities. (ST)

This study investigates the visual information storage capacity in 5-, 8-, 11-, and 21-year olds. A partial report technique is used to assess the amount of information that children can take in and what the course of information loss was over time. (DP)

Contrary to Piaget's predictions, adolescent retardates and 9-year-old normals were more susceptible to the Oppel-Kundt Illusion than high school sophomores and adults. No group differences were found on the Poggendorf Illusion. (MH)
