Unit 5:developing Person Flashcards
Zygote
The fertilized egg; it enters a two-week period of rapid cell division and develops into an embryo. Called the germinal period/stage because it is the size of a germ it attaches to the placenta
Developmental psychology
A branch of psychology that studies physical, cognitive, and social change throughout the lifespan
Embryo
The developing human organism from about two weeks after fertilization through the second month. The bodies organs begin to function
Fetus
The developing human organism from nine weeks after conception to birth. Known as the fetal stage
Toratogens
Agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm this places the child at risk
Fetal alcohol syndrome (FAS)
Physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, symptoms include noticeable facial mis-proportions.
Reflexes
Babies are born with sensory equipment and reflexes that facilitate interaction.
Rooting reflex
A babies tendency, when touched on the cheek, to open the mouth and search for the nipple. This is a survival reflex
Palmore reflex
Infant clothes his hand and grips your finger (can also result in flexion) when palm is tickled
Babinski reflex
Toast fanout word one soul of the foot is stroked. Helps with walking later
Sucking reflex
Begins to suck when nipple or anything touches the lips
Moro reflex
Extends arms then bends and pulls them toward the body with the brief cry; caused by loud sound or sudden movements
Orientation reflex
Response to changing stimulant, how they react to changing faces are voices, like to look at things about 8 to 12 inches away
Habituation
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner. How they discriminate color shape sounds numbers and physics
Nerve cells before and after birth
Neural network start to learn. They grow very quickly at first but slow down later
Maturation
Biological growth processes that enable orderly changes in behavior, relatively influenced by experience. Not due to environment. As infants muscles mature, becomes more complicated
Motor development
Infants more complex physical skills-sitting, standing, walking-develop any predictable sequence his actual timing is a function of individual maturation rate and culture.
Nature and nurture
G
Cognition
All the mental activities associated with thinking, knowing, remembering, and communicating
Schema
A concept or framework that organizes and interprets information
Assimilation and accommodation
Assimilation is interpreting one’s new experience in terms of one’s existing schemas. Accommodation is adapting one’s current understandings or schemas to incorporate new information
Piaget’s cognitive development stages
Piaget described cognitive development in four stages. He believed that children experience spurts of change followed by a greater stability as they grow
Stage one of Piaget’s cognitive development theory: sensorimotor
Experiencing the world through senses and actions (looking, touching, mouthing, and grasping). Usually occurs from ages 0 to 2.
Object permanence
Infants younger than six months do not understand that things continue to exist when they are out of sight. They think it disappears from existence. Out of sight out of mind
