Studies were designed to test the prediction that spatial search strategies in infants may be influenced by locomotor experience. The pattern of findings suggests that infants with efficient modes of locomotion are more likely than others to profit from the experiences generated by locomotion. (RJC)

Studied the effects of adult intervention on 10-month-old infants' level of attention to objects. The overall duration of infant attention increased during medium intervention when the duration was compared to that of the control group. Low attending infants attended more in medium and high intervention, while high attending infants were…

Findings indicate that infants can detect regularity in spatiotemporal series; will develop expectancies for events in the series; and will act on the basis of those expectancies even when their actions have no effect on the stimulus events. (PCB)

Briefly reviews research concerned with symbolic development in children born prematurely. Focus is on the complex process of sorting out the effects of biological maturation and environmental experience in the study of the emergent processes, and examining the effects of biological risk and environmental opportunity in determining developmental…

Delay/response inhibition in the presence of an attractive stimulus and compliance with maternal directives in a clean-up task were observed among subjects 18, 24, and 30 months of age. Results suggested (1) achievement of self-control is a major developmental accomplishment, and (2) individual differences in self-control emerge and are…

A summary of research on affective and cognitive development in young children with Down syndrome notes that affect and cognition seem as closely interrelated in Down syndrome as in nonretarded children. Overall findings indicate that from birth to two, children with Down syndrome experience significant delays in development of both affective and…

Results of a study conducted in 14 villages of Sui Lin Township, Taiwan, suggest the hypothesis that, under conditions of extreme economic impoverishment and among children within populations where energy protein malnutrition is endemic, there is an inverse relationship between incidence of morbidity in infancy and measures of motor and mental…

The research project is being supported by a grant from the Bureau of Research, U.S. Office of Education (OEC 6-10-235)

Uncertainty was researched as a perceptual structure which mediates the transition from sensorimotor activity to language. The guiding notions are that the attentional system is geared to uncertainty from the beginning of life and that a speaker's language use is coordinated with this system as it emerges. (Author)

Reports on connectionist models that simulated the formation of global-level and basic-level representations in young infants; revealed a global-to-basic order of category emergence; uncovered formation of two global-level representations--initial "self-organizing" perceptual level and subsequent "trained," non-perceptual…

Integrates recent views of early perceptual-cognitive growth with accounts on the development of communication in infancy. Emphasizes supporting evidence for a view that combines innate perceptual and constructive mechanisms with associative memory in explaining how human infants process information. Also considers how the sociocultural…

Investigates the relationship between self-recognition and self-evaluative emotions in two studies on 27 children aged 9-24 months and 44 children aged 22 months. The results of both studies indicate that embarrassment but not wariness was related to self-recognition. (RJC)

Investigated 314 young children who had neonatal hyperbilirubinaemia. Results indicated that these children managed less well in neurological and psychological tests, had poorer school marks, and more often attended special classes than did members of the control group. (RJC)

Two studies found infants' scores on the Range of State Cluster of the Neonatal Behavioral Assessment Scale with Kansas Supplements to correlate significantly with visual discrimination performance at three months of age. The correlation with behavioral state organization contradicted the prediction that orientation scores would predict visual…
