When learning object function, infants must detect relations among features--for example, that squeezing is associated with squeaking or that objects with wheels roll. Previously, Perone and Oakes (2006) found 10-month-old infants were sensitive to relations between object appearances and actions, but not to relations between appearances and…

A study was undertaken to explore the relationship of mothers' language to infant development in terms of the infants' development of sensorimotor intelligence. Specifically, the study chronicled the infants' advances in sensorimotor development from J. Piaget's Stage II to Stage III as a possible explanation for changes in maternal language. It…

The purpose of this research is to show that the logical formula for equivalence, (A=A; but is not A'), originates in the early manual actions of the young child. Having two hands that are bilaterally opposed and initially function in bilaterally symmetrical action might serve to structure the form of early sensori-motor experiences and this…

What data, problems, and concepts are most relevant in determining the role of stimulation in human development? A critical analysis of the relationships between long term stimulation, behavior, and cognitive functioning and development points up biases and gaps in past as well as contemporary approaches. Each of the four sections of this paper…

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…
