Developmental functions: no change: ability present at/before birth that remains constant across lifespan; ex. discriminate b/w high & low pitch sound, continuous change: ability not present/very immature at birth, develops over months/years. Prenatal development: germinal: first 2 weeks, beginning when 1 sperm fertilizes female egg (zygote) - > mass of cells, attaches to mother"s uterus. > rubella: blindness, deafness, heart defects, mental retardation. > fetal alcohol syndrome (fas): intellectual (iq), fine-and-gross motor impairments, poor adaptive functioning. > nicotine: miscarriage, premature birth, low birth weight; also, ets from fathers. > heroin/cocaine: experience withdrawal after birth: kisilevsky & muir: loud sound=increases in fetal heart rate & body movements, 3rd trimester. > stop responding to repeated presentations of vibro-acoustic & auditory stimuli (st memory) > sounds heard repeatedly during fetal development (lt memory) > birth: 25% of eventual adult weight. > first areas: basic survival functions (heartbeat, breathing); last areas: prefrontal cortex= highest-level cognitive function.
