This study investigates the nature and the factor structure of infant intelligence. The Bayley Mental Scale items were administered. According to the analysis, intelligence at any age is a set of separate mental abilities at each age, and there are a variety of paths through which mental development occurs. (JAZ)

Fifteen 1-year-olds without otitis media were compared to 12 babies who were otitis positive. No significant differences were detected on the Bayley Scales of Infant Development or the Sequenced Inventory of Communication Development (SICD) Receptive scale. However, the otitis-positive group exhibited lower SICD Expressive scores than the…

The issue of congruence and consistency among multiple team estimates of child functioning was addressed. Multihandicapped children were assessed by an interdisciplinary developmental diagnostic team using several developmental/behavioral scales. Assessments revealed evidence of team congruence in diagnosis. Data analysis indicated consistency…

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

Neonatal assessments should provide valid estimates of behavior and neurological status, reflect recovery from acute effects, predict subsequent outcome, and point to specific intervention strategies for any problems noted. The authors report relations among measures designed to evaluate early behavioral capabilities and dysfunctions in areas…

This paper presents a study of the relationship between scores on the Bayley measures of mental and motor development administered at 8 months of age and performance on measures of cognitive development and school achievement administered at ages 4, 5, 6, and 7. Also studied are changes in this relationship which occur when children with extreme…

Measures of visual and tactual recognition memory, tactual-visual transfer, and object permanence were obtained for preterm and full-term infants. Measures of tactual-visual transfer were correlated with later intelligence measures up to the age of five years. These correlations were independent of socioeconomic status, medical risk, and early…

Compared cognitive functioning of infants--at 8 and 18 months--with varying levels of prenatal cocaine exposure. Found that, with risk and polydrug exposure controlled, exposure groups did not differ at 8 months on Bayley Scales or recovery to a novel stimulus. Infants with heavy exposure or high environmental risk declined in mental development…

The primary purpose of this study was to examine uneven early development in premature infants. A multiple regression analysis was performed in which birth weight, length of gestation, length of assisted feeding, and length of ventilation were used to predict the descrepancy between a child's Psychomotor and Mental Scale scores on the Bayley…

This study attempted to find which factors determine the course of mental growth. The hypotheses were as follows: (1) early growth rates are rapid, chaotic, and uneven; (2) intellectual functions become more complex at age 2; (3) language is of overriding importance in intellectual growth; (4) more developed individuals have a longer infancy…

Separate dimensions of infant cognition were compared with parental general- and specific-cognitive abilities for 182 adoptive and 164 nonadoptive families. More parent-offspring resemblance was present when 24- rather than 12-month Bayley factors were used. Bayley factors were more related to parental g than to specific abilities. (Author/RD)

Sixty subjects age 6 to 30 months were assessed with the Bayley Mental Scale of Infant Development (BMSID). Mean scores were substantially higher than standardized norms would predict, indicating that Bayley norms need to be revised, and that strict interpretation of the BMSID may result in misdiagnosis of some infants with developmental…

Thirty children (under 24 months of age) referred to an early intervention program were administered 3 developmental assessments. Although the Griffiths' Mental Development Scales correlated well with the Bayley Scales of Infant Development and the Battelle Developmental Inventory, the Griffiths' age equivalents were considerably higher than the…

Assessments of the home environments of 116 families whose twins were participants in a longitudinal study of early mental development were conducted. Predictions of offspring intelligence scores increased from ages six months to six years old. Although home/family variables were related to mental development, so were parental education and SES.…

This speech offers a guide to identifying and teaching high-risk children, those who exhibit a lag in development severe enough to be a handicap in learning. The high-risk children focused on are those whose developmental lag is frequently not recognized until they fail in school. The two major areas of neurodevelopmental learning disorders are in…
