There is general consensus that the representation of the human face becomes functionally specialized within the first few months of an infant's life. The literature is divided, however, on the question whether the specialized representation of the remainder of the human body form follows a similarly rapid trajectory or emerges more slowly and in…

DO CHILDREN RAISED IN ENVIRONMENTS ASSOCIATED WITH LATER DEFICITS IN PSYCHOMETRIC INTELLIGENCE SHOW ANY DEFICITS DURING INFANCY AND, IF SO, WHEN DO SUCH DEFICITS APPEAR AND WHAT ABILITIES ARE AFFECTED. ARE THE ENVIRONMENTAL FACTORS ASSOCIATED WITH EARLY DEVELOPMENT OF INTELLIGENCE. FIFTY-ONE SLUM INFANTS AND A CONTROL GROUP OF 51 NON-SLUM INFANTS…

In this study, free play with toys having unambiguous functions was examined to test the hypothesis that a basic cognitive metamorphosis is associated with the new competences displayed in children at about 12 months. Functional play was observed in 64 children at 9 1/2, 11 1/2, 13 1/2, and 15 1/2 months of age. Six sets of toys with 36…

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

The Mayes Motor Free Compilation (MMFC) assesses mental ability in young (under age 2) children with motor disabilities. This study evaluated the concurrent validity of the MMFC by administering it and the Bayley Scales of Infant Development to normal children. Findings suggest that the MMFC provides a valid estimate of mental age, even without…

This study investigated the concurrent validity of the Mayes Motor Free Compilation (MMFC) using the mental scale of the Bayley Scales of Infant Development (BSID) as the criterion variable with 50 typically developing preschool-aged children. Results indicated that the MMFC and the BSID scores were significantly and positively correlated.…

This study examines the effects of sex, socioeconomic status, birth order and birth spacing on the cognitive performance of 12-week-old infants. A brief review of research on neonatal cognitive ability is followed by a description of the study itself. The subjects, 189 three-month-old Caucasian infants (61 first borns, 58 second borns, and 49…
