Document Summary

Growth: increase in size of the individual; in infancy and early childhood it is typically assessed through measurement of height/length, weight, and head circumference; often growth can be easier to observe and measure than development. Ossification: the process of converting cartilage to bone. Myelination: the process where myelin is laid down on the nerves of the brain; when parts of the brain myelinate, it allows or improves the function of that area such as movement or vision. Irreducible needs: the child"s basic and essential needs that must be met for healthy development. Zone of proximal development: behaviours that are on the edge of emergence; the gap between the child"s actual performance when operating alone and the child"s potential performance when assisted by more knowledgeable adults or children. Gross motor skills (learned behaviors involving large muscles) Fine motor skills (learned behaviours involved small muscles) Observe habituation (decline in interest) and dishabituation (renewal level of interest)
