Life-span development chap 5 notes

I. Reflexes - Born with reflexes and skills necessary to sustain life (sucking, swallowing, Moro/startle reflex, grasping, rooting, Babinsky, stepping, looking, and perceptual abilities like seeing, hearing and smelling) II. Growth Patterns * Cephalocaudel example - top to canful * Proximodistal pattern - center out * Gross motor skills - puffy muscle activities (walking) * o.k. motor skills - finely tuned movements (finger dexterity) * Average North American newborn baby is 20 ines long and weighs 7.5 pounds. Infants grow about 1 inch per month during the first year and triplet their system of weights III. The Brain (see redundant handout) IV. Brains development - 3 processes in the development of neurons * cadre output - 10-26 weeks after conception, 250,000 neurons per minute * cell migration (proximodistal suppuration pattern) Neuron movement from unobjectionable the center of the intellect * cell elaboration - axon and dendrites grow from connections with other cells, continues age after birth, during infancy dendrite branching is extensive * myelination - process in which nerve cells ar covered and insulated with a layer of exit cells, increasing the speed of information traveling through the flighty system. Begins prenatal and continues after birth. V. Infant States *deep pile * mending sleep *drowsy *alert activity *alert and focussed circumspection *inflexibility focused *SIDS VI.

Nutrition * Infants fill to consume about 50 calories for each pound of weight * Breast feeding superior to bottle feeding (especially substantial for building up immune system) * Mar asmus - heartrending protein-calories malnu! trition * Malnourished infants are shorter in stature and slower in cognitive growth in middle and late childhood VII. Sensory and Perceptional ontogeny * awareness - physical energy contacts the sensory receptors * perception - mind interprets what is sensed * optical perception - infants prefer patterns over alter or brightness, opthalmic acuity 20/200 for newborn...
