Presents results of two experiments which measured contrast sensitivity function in infants. Information concerning development of visual acuity, low frequency attenuation, and sensitivity to contrast were collected. Results provide an approximate picture of and means for detection of infants' pattern information. (Author/DB)

The relationship between reading ability and recognition of four kinds of perceptual stimuli for purposes of reading disability diagnosis was investigated. The sample consisted of 84 male grade-3 pupils who were matched on intellectual ability but who differed in reading proficiency. Three groups, based on a 6-month discrepancy either above or…

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…
