Development psychology"s major issues: continuity and stages, development is a slow, continuous shaping process, stage theories contribute a developmental perspective on the life span. Prenatal development and the newborn: stability gives one"s identity. Ii: conception, the mom was born with all of the immature eggs and the dad started producing sperm cells ever since puberty. Originally, he would have a rate of more than 1000 sperm. It is when after puberty, the mother"s ovary would release a mature egg. It"s all a race among the 250 million sperm to reach a cell thats 85,000 times their own sizes. 3: those sperms that have reached the egg would have released digestive enzymes that ate away that protective coating. Once it has penetrated that coating and was accepted by the egg, the egg"s surface block out all of the other sperm. From here, the egg and sperm become one: prenatal development, after a period of two weeks, zygotes soon multiply into you.
