"Tangible as tissue": Arnold Gesell, infant behavior, and film analysis.

Ontogenetic Correspondences in the Supine and Prone Postures of the Human Infant *

In the early human fetus the arms are much longer than the legs. At birth, arms and legs are almost equal in length. In the young adolescent the legs are longer than the arms. This progressive reversal in proportions reflects evolutionary changes wrought over many millions of years. The gluteal musdes of the newborn infant are notably under-developed, a condition comparable to that of the chimp...

High Quality of Infant Chondrocytes in Comparison with Adult Chondrocytes for Cartilage Tissue Engineering

BACKGROUND Tissue engineering is used for the treatment of many diseases, and the ideal cell source for cartilage tissue engineering is chondrocytes. The main limitation of chondrocyte is the low number of cells in cartilage tissue engineering. This study investigated a suitable cell source with high proliferation rate to obtain a large number of chondrocytes. METHODS Adult cartilage t...

The Psychology of Early Childhood

Infant Behavior Research *

An introductory word may be said about the background of our research program. The Clinic of Child Development started on a small scale back in 1911, as part of the New Haven Dispensary. It then functioned as a diagnostic and advisory dinic, dealing chiefly with backward and problem children of school age. But we soon developed a research interest in children of preschool age and considered the...

Tonic Symmetry in the Inverted Human Infant

Developmental studies of infant behavior have now assumed, especially to the pediatrician and neurologist, a position both of theoretical interest and clinical significance. The impetus for this has been largely through systematic investigations such as those of Gesell and his collaborators at the Yale Clinic of Child Development. A postural reflex of infancy bearing on a facet of their work is...
