PSY 0010 Lecture Notes - Lecture 10: Fetal Alcohol Spectrum Disorder, Almost Surely, Developmental Disorder
Document Summary
Developmental psychology: the study of continuity and change across the life span. There are three prenatal stages (from conception to birth). Germinal stage: the 2-week period that begins at conception. Zygote: a fertilized egg that contains chromosomes from both a sperm and an egg. Embryonic stage: the period that lasts from the 2 nd week until about the 8 th week. Fetal stage: the period that lasts from the 9 th week until birth. Myelination: the formation of a fatty sheath around the axons of a neuron. Males release androgens which prompt the development of the wolf an system and a mullerian-inhibiting substance. The womb is an environment that affects an unborn baby in many ways. The placenta is the organ that links the bloodstreams of the mother to the unborn baby that permits the exchange of materials. Teratogens: agents that damage the process of development, such as drugs and viruses.
