Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age.

Examined consistency in behavioral state organization for 30 fetuses and neonates. Assessed heart rate pattern and presence or absence of eye and gross body movements during sleep, finding quiet sleep (QS), active sleep (AS), and indeterminate states in nearly identical proportions. Duration of enclosed QS epochs provided only stable measure of…

This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of…

Studies of children who initially display high rates of antisocial behavior indicate such children are more likely to persist in this behavior than those who initially show lower rates. (Author/MP)

Studied 112 preterm infants to determine developmental changes and stability of individual differences. Results indicate significant developmental gains with age, and highly significant individual stability of performance across age. (RJC)

The role played by neuroembryological forces in shaping brain development is well documented in Nowakowski's (1987) article. Additional mechanisms whereby experience may influence brain structure and function are outlined. Several routes exist by which postnatal experiential influences may produce long-term alterations in behavior and…

This study examined the ways in which exposure to moral reasoning statements affected the subsequent behavioral choices of 144 seventh-, eighth- and ninth-grade boys at different stages of moral judgement. The presentation of reasoning had different effects on the behavioral choices of subjects at two different stages. (Author/SB)

Neonates born without complications to healthy mothers at 14,000 feet or at 490 feet above sea level were evaluated at 24-36- and 48-60-hours-of-life. In comparison with low-altitude infants, high-altitude infants were significantly lighter, shorter, had a smaller arm circumference, and presented more signs of behavioral immaturity in interactive…

Examined associations between tympanic membrane (TM) temperature asymmetries and biobehavioral attributes of 4- to 8- year-old children. Found shared patterns of associations that linked TM temperature lateralities to individual differences in behavior and socioaffective difficulties. Found that warmer left TMs were associated with affectively…

Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

The Neurobehavioral Assessment of the Preterm Infant instrument was developed by means of pilot, exploratory, and validation studies. The validation study tested the generalizability of results for different cohorts, test versions, hospitals, and examiners. Seven stable functions were identified: motor development; scarf sign; popliteal angle;…

Describes a study designed to test (1) the effects of an educational prosocial television program on learning and behavior of kindergarten children; and (2) two types of training, verbal labeling and role playing, designed to help children learn the content of the program. Children were able to generalize learning. (ED)
