Document Summary

developmental psychology: they study how we change from the moment of birth to death, how we change, morally, physically, psychologically. development: patterns of change that begin at conception and continue throughout the lifespan. If we have stages then from one stage to the next we see major significant changes ex. changing from a caterpillar to a butterfly, they believe development occurs in a continuous and stage way. critical periods: are there periods throughout the lifespan that are more critical than others. conception is going to take place when the body of a healthy women releases an egg and then she has sexual intercourse with a healthy male using no protection. over 200 million sperm are going to be released. when the sperm gets to the egg they release enzymes, the egg then releases a chemical preventing any other sperm from getting in, and the egg then pulls the sperm in.
