Genes segments of dna that make chromosomes. Nature gene combination and biology we are born with. Teratogen - chemical/virus that causes harm to the embryo or fetus.

Those with enriched environments during development have enriched brain cells (and the same correlation goes for impoverished environments) Infantile amnesia cannot remember memories from young years. Sensorimotor birth to 2 years take in the world via senses. Object permanence awareness that objects continue to exist when out of sight. Preoperational 2 years to 6/7 years can represent things with words and pictures but cannot perform mental operations. Conservation the amount stays the same even if the shape changes.
