Cross Sectional Research
A research design that compares groups of people who differ in age but are similar in other important characterisitics

Function of the Placenta
protects and nourish the developing embryo sustaining life via the umbilical cord
formed from the thin line called the Primitive Streak located down the middle of the embryol;22 days after conception the line becomes the Neural Tube developing into the CNS(brain and spinal cord)
the process, beginning about 10 days after conception, in which the developing organism burrows into the placenta for nourishment and protection
A condition in which a person has 47 chromosomes instead of the usual 46, with 3 copies of chromosome 21

A disease of chronic malnutrition during childhood in which a protein deficiency makes the child more vulnerable to other disease, such as measles, diarrhea and influenza
Infant's Earliest Sensorimotor Activities at the stages of 2, 3, 5, and 6 according to Piaget
Stage 2: 1-4mos accommadiation and coordination of reflexes; Stage 3: 4-8 mos an awareness of things,responding to people and objects; Stage 5: 12-18mos experimentation and creativity (teddy bear in flushing toilet); Stage 6: 18-24mos considering before doing mental combinations
Differences in Skinner and Chomsky Language Theories
Skinner:language is learned by verbal learning, reinforced spontaneous babbling; Chomsky: language is learning is innate
A-not-B error (also known as "stage 4 error" or "perseverative error") is a phenomenon uncovered by the work of Jean Piaget in his theory of cognitive development of children. The A-not-B error is a particular error made by young children during substage 4 of their sensorimotor stage.
