A sample of 107 subjects including kindergarteners, fifth graders, high school sophomores, parents of kindergarteners, and master artists were presented with a 108-item color perception test to investigate surface color perception at these age levels. A set of surface color perception rules was generated. (GO)

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)

Investigates the problem young children have in constructing diagonals, noting that, on the whole, they can not make diagonals in the horizontal/vertical configuration. (HOD)

Evaluates preschoolers' ability to distinguish left-right mirror-images of objects on a memory task and ability to name rows of objects on a page in a consistent lateral direction. Abilities were assessed first without specific instructions on the relevance of left-right information and then with instructions. (Author/AS)

Explored the relationship among conceptual tempo, age, sex, and performance of preschool children on the visual association subtest of the Illinois Test of Psycholinguistic Abilities. (Author/DB)

Investigated ability of young children to interpret aerial photographs and maps, sought age and/or cognitive development differences, and probed whether or not some environmental features were more consistently recognized than others. (Author/DB)

Ninety-eight participants from 5 age groups with mean ages of 6, 8, 10, 22, and 72 years were tested in a series of speeded number discriminations. Found that response time slope as a function of number size decreased with age for numbers in the 1-4 range. (MDM)

Examined age-related changes in visual selective attention--ability to resist interference--in children 5 to 12 years old and adults. The interference effect on stimulus evaluation did not discriminate between age groups; however, the interference effect on correct response activation showed a pronounced age-related reduction, suggesting a…

Two experiments explored the behavior of 20 Asian elephants ("Elephas aximus") in simultaneous visual discrimination tasks. In Experiment 1, 7 Burmese logging elephants acquired a white+/black- discrimination, reaching criterion in a mean of 2.6 sessions and 117 discrete trials, whereas 4 elephants acquired a black+/white- discrimination in 5.3…

Developmental studies of face processing have revealed age-related changes in how infants allocate neurophysiological resources to the face of a caregiver and an unfamiliar adult. We hypothesize that developmental changes in how infants interact with their caregiver are related to the changes in brain response. We studied 6-month-olds because this…

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…

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)

Analyzes sex-related differences between mental rotation rate and spatial ability among adults, 14-year-olds, and 9.5-year-olds to determine the extent to which rotation rate is a correlate of various abilities. (HOD)

Some infants, soon after birth, are capable of storing visual information as reflected in their ability to detect and respond to change in the immediate environment. (Author)
