Chapter 6 Flashcards
development
the physiological, behavioral, cognitive, and social changes that occur throughout human life, which are guided by both genetic predispositions (nature) and by environmental influences (nurture)
infancy
the developmental stage that begins at birth and continues to one year of age
childhood
the period between infancy and the onset of puberty
adolescence
the years between the onset of puberty and the beginning of adulthood
adulthood stages
emerging, early, middle, older
conception
when an ovum, or egg, previously stored in one of the mother’s ovaries, matures and is released into fallopian tube
zygote
a fertilized ovum,
differentiate
when dividing cells in a zygote start to take on a different function
amniotic sac
the fluid-filled reservoir in which the embryo (soon to be fetus) will live until live birth, which acts as both a cushion against outside pressure and as a temperature regulator
placenta
an organ that allows the exchange of nutrients between the embryo and the mother, while at the same time filtering out harmful material
umbilical cord
links the embryo directly to the placenta and transfers all material to the fetus
teratogens
substances that harm the fetus
fetal alcohol syndrome
a condition caused by maternal alcohol drinking that can lead to numerous detrimental developmental effects, including limb and facial abnormalities
rooting reflex
cheek stroked->turns toward stroking, opens mouth, tries to suck. to help get food
blink reflex
light flashed in eyes->closes eyes. to protect from harmful stimulus
withdrawal reflex
a soft pinprick is applied to the sole of the baby’s foot->baby flexes the leg. keeps infant away from painful stimuli
tonic neck reflex
laid down on back->turns its head to one side and extends the arm on same side. to develop hand eye coordination.
grasp reflex
object pressed into palm->baby grasps object. helps with exploratory learning
moro reflex
loud noises or sudden drop in height while holding baby->extends arms and legs and brings them in as if to grab. to protect from falling+hold onto mothers.
stepping reflex
baby suspending over a surface and moved forwards->baby makes stepping motions. to encourage motor development
Erik Erikson’s childhood development skills
children must attain initiative, competence, and independence
Piaget’s stage model of cognitive development
children gain their cognitive ability in developmental order
schemas
patterns of knowledge in long-term memory, that help them remember, organize and respond to information. developed by children
assimilation
use already developed schemas to understand new information
