Ch.4 Flashcards
Sequence of parental development: CONCEPTION
A single sperm cell (male) penetrates the outer coating of the egg (female) and fuses to form one fertilized cell.
Sequence of parental development:
ZYGOTE
A fertilized egg that grows to about 100 cells, which become increasingly diverse.
How many days does it take a zygote to become an embryo?
14
How many weeks does it take for an embryo to turn into a fetus?
9.
Sequence of parental development: EMBRYO
The developing human organism from about 2 weeks after fertilization through the second month.
Sequence of parental development: FETUS
The developing human organism from 9 weeks after conception to birth.
Teratogens
(“Monster maker”)
Agents such as chemicals and viruses that can reach the embryo or fetus during prenatal development and cause harm.
Maturation
The development of the brain unfolds based on genetic instructions, causing various motor skills and mental functions to develop in sequence— standing before walking, babbling before talking— this is called maturation.
Habituation
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner
Rooting reflex helps babies locate food T or F?
True
Critical period
An optimal period early in the life of an organism when exposure to certain stimuli or experiences produces normal development
Cognitive development
Jean Piaget believed that the driving force behind intellectual development is our biological development amidst experiences with the environment. Our cognitive development is shaped by the errors we make.
Stage one: SENSORIMOTOR
The stage (from birth to nearly 2 years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities.
Stage two: PRE OPERATIONAL
The stage (from about 2 to about 6 or 7 years of age) during which a child learns to use language but does not yet comprehend the mental operations of concrete learning.
Conservation
The principle (which Piaget believed to be apart of concrete operational reasoning) that properties such as mass, volume, and number remain the despite changes in the forms of objects.
Egocentrism
The pre operational child’s difficulty taking another’s point of view
Theory of mind
People’s ideas about their own and others metal states— about their feelings perceptions and thoughts and the behaviors these might predicts
Stage 3: concrete operational stage
The stage of cognitive development (from about 7 to 11 years of age) during which children gain the mental operations that enable them to think logically about concrete events
Stage 4: formal operational
The stage of cognitive development (normally at age 12) during which kids begin to think logically about abstract concepts
Schemas
Schemas are mental molds into which we pour our experiences
