Document Summary
10. 1 physical development from conception through infancy. Developmental psychology: the study of human physical, cognitive, social, and behavioural characteristics across the lifespan. The transition between developmental stages involves rapid shifts in thinking and behaving and fundamental shifts in the types of abilities a child can perform. Zygote: the initial cell formed when the nuclei of an egg and sperm fuse. Germinal stage: the first phase of prenatal development, which spans from conception to two weeks. Embryonic stage: weeks 2-8, during which time the embryo begins developing major physical structures such as the heart and nervous system, as well as the beginnings of arms legs hands and feet. Fetal stage: spans week 8-birth, during which time the skeletal organ and nervous systems become more developed and specialized. Beginnings of human brain can be seen during embryonic stage. By 4 weeks, the fore, mid and hind brain are apparent. By 11 weeks cerebral hemisphere cerebellum and brain stem are apparent.
