Life Span Perspective

Life Span Perspective


University of Phoenix


Human development is understood only in the light of thorough knowledge and understanding of the complete makeup of man (Berk , 2000 . However the accumulation of bases and proofs for the evidences in this understanding would not be possible without utilizing scientific methods . These evidences helped cement psychology 's place in the realm of scientific knowledge . Only when psychology employed scientific methods did it come to be a force to reckon with among many of the pure and applied

sciences (Bootzin , 1991 . In other words life-span development deals with an individual 's behavioral development in its entirety .

It is amazing to imagine the difficulties that the egg and sperm go through just before they meet and nature 's way of providing that these two will unite and form into either a male or a female human being

Prenatal period

The ly development of the human organism begins as soon as a spermatozoon fertilizes the ovum . This is the prenatal period extending from conception to birth and lasts about 266 days (around nine months During this period , a single cell divides and grows to form 200 billion cells . It consists of three successive phases : the germinal , embryonic and fetal periods (Papalia et al , 2002


The postnatal period refers to birth and onward . Birth changes all the prenatal , watery environment of the fetus . The newborn child during the first month of life outside the mother 's uterus is called a neonate Immediately after being born , a newborn 's physiology undergoes...
