Chapter 4 - Developing Through the Life Span Flashcards
zygote
The fertilized egg; it enters a two week period of rapid cell division and develops into an embryo
embryo
The developing human organism from about two weeks after fertilization through the second month
fetus
The developing human organism from nine weeks after conception to birth
teratogens
agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
fetal alcohol syndrome
physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, symptoms include noticeable facial misproportions
rooting reflex
A baby’s tendency, when touched on the cheek, to turn toward the touch, open the mouth, and search for the nipple
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
maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
schema
A concept or framework that organizes and interprets information
assimilation
interpreting ones new experience in terms of one’s existing schemas
accommodation
adapting one’s current understandings (schemas) to incorporate new information
cognition
all the mental activities associated with thinking, knowing, remembering, and communicating

object permanence
The awareness that things continue to exist even when not perceived
Preoperational stage
in piaget’s theory, The stage (from about 2 to 6 or seven years of age) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic

formal operational stage
in piaget’s theory, The stage of cognitive development (normally beginning about age 12) during which people begin to think logically about abstract concepts
stranger anxiety
The fear of strangers that infants commonly display, beginning by about eight months of age
attachment
an emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation
