Document Summary
Structured observation: looking time, pointing, verbal responses, interaction with the environment, physiological, has. Within (one group with two different conditions) group observations. Triangle helping vs. square hindering: babies prefer the video of the helping triangle, when presented with two toy options, babies will choose the triangle. Heritability: the extent to which individual differences in complex traits are due to genetic factors. Gene x environment: genes environment. E. g. , the presence of a particular enzyme can moderate the effect of maltreatment: environment genes. Epigenetics: in addition to changes in genetic sequence, our environment can affect gene expression. Neural tube: primitive spinal cord top of which eventually forms the brain. Oligodendrocytes and astrocytes are both types of glial cells. W 3-6: embryo, neural tube begins to form, heart, muscles, ribs, backbone, and digestive tract start, external body structures, senses of touch develops, embryo can ove. W 9-12: fetus, nervous system & organs become more organized: w. 12-24.
