Document Summary
Both biological and environmental factors affect how one develops. Parental practices (eg. how a baby is positioned to sleep) affects motor development. People are products of both nature and nurture; thus the whole dichotomy of one being right is wrong. Embryo- baby starts developing organs; fetus- baby grows and looks like human; baby- able to survive outside womb. Hormones in the womb have effects on the baby. If mother is depressed or anxious, can cause light weight babies. In a study, found that levels of testosterone are correlated with range of behaviours later in childhood. Teratogens- agents that can cause abnormal development in the womb; length and amount of exposure results to the deformity of the child.

Specific areas within the brain mature and become functional: 2.
