One of the world's most famous pyramids is not located in Egypt but is on a music album cover by the band Pink Floyd. However, not a pyramid but a prism, the iconic image of a beam of light turning into a rainbow is a powerful symbol that captures the complexities of colour perception across cultures and individuals. This study examines how…

Research has consistently shown that difficulties in facial emotion recognition (FER) are associated with peer problems and internalizing symptoms during middle childhood. However, no longitudinal research has investigated the direction of effects, that is, how these constructs influence each other across time. In this preregistered three-wave…

The vigilance reinforcement hypothesis (VRH) asserts that errors in signal detection tasks are partially explained by operant reinforcement and extinction processes. VRH predictions were tested with a computerized baggage screening task. Our experiment evaluated the effects of signal schedule (extinction vs. variable interval 6 min) and visual…

The American Academy of Pediatrics recommends vision screening of all children between 3 and 5 years of age, and states have mandated vision screening for all school children. Participants were three 4-6-year old school children with either a developmental delay or autism who scored "could not test" on the state required vision screening.…

Described is a system for evaluating a child's learning pattern. It is explained that the evaluation is based on a social history, visual screening (including acuity, functional skills, pursuit skills and binocularity skills), auditory evaluation, motor assessment, and academic testing. (CL)

USING A SAMPLE OF 94 CHILDREN (31 TO 54 MONTHS OLD), THIS STUDY COMPARED EIGHT VISION SCREENING PROCEDURES FOR YOUNG CHILDREN IN THE ABILITY TO TEST FOR SEVERAL VISUAL FUNCTIONS, AND PREFERENCE AMONG THEM BY CHILDREN. THE SUBJECTS WERE ORIGINALLY TESTED USING THE EIGHT SCREENING TESTS, AND 6 MONTHS LATER 40 OF THE CHILDREN WERE RETESTED FOR…

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…

Twenty-eight kindergarten children (5-6 years old) were tested in order to identify children with learning disabilities and to compare tests results. (Author)

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

The effects of maturational lag and innate perceptual-motor language learning disabilities on primary-grade children's school performance are discussed. Early identification of these learning disabilities is emphasized. A pilot study using 280 second- and third-grade children is described in which the feasibility of whole classroom screening to…

Vision assessments were provided to 297 preschoolers in nine Head Start programs in New York State. The protocol used provided a thorough evaluation and required only seven minutes per child. Sixty-three children (21.2%) were referred for further evaluation. Visual deficits detected included decreased acuity, strabismus, astigmatism, and…

Through a cooperative approach, four area school districts and a State university solved the budgetary problem of obtaining objective proof of the need for programs for children with learning disabilities. (Author)

Although several vision screening techniques are available for infants, none is routinely used. Visual deficits are often first detected through required preschool vision screenings, which vary in their comprehensiveness. No standardization for testing or administration exists. Some of the testing procedures used may have inappropriately high…

Theoretical implications of individual differences among infants in responsiveness to visual novelty being predictive of later intelligence differences are discussed. Issues discussed include: continuity of intelligence over development, relation of aspects of information processing to intelligence, role of hereditary and environmental influences…
