Prior studies found individual differences in visual recognition memory during infancy were related to individual differences in later intelligence. This paper discusses methodological issues in the measurement of infant visual recognition, the significance of previously obtained predictive validity coefficients, and the theoretical question of…

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 authors discuss methodological and theoretical issues in psychological investigations of infant attention, fixation times, habituation, and intelligence. A consensus on how to measure individual differences in habituation has not been reached. The relation between IQ and attention is discussed. (RD)

This paper presents evidence that the Snyder/Pope Visual Memory Technique using the Bender-Gestalt Test is a useful predictor of reading ability for first-grade children. Short-term visual recall appears highly related to the Grade 1 reading task and should be assessed when children begin learning to read. (Author/SJL)

The construct and predictive validities of the Perceptual Ability Test (PAT) were examined. The results indicate that each of the subtests exhibits different predictive validity. A linear combination of PAT subtest scores was found to be more predictive of first-year dental school technique performance than the total PAT score. (Author/MLW)

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…

The agreement between visual analysis and the results of the split-middle method of trend estimation was examined using a set of 24 stimulus graphs and 30 raters. Results revealed poor agreement between the two methods, and low sensitivity, specificity, and predictive ability for visual analysis in relation to statistical inferences. (JDD)

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…
