CH 4: Development Through the Life Span Flashcards
Developmental Psychology
A branch of psychology that studies physical, cognitive, and social change throughout the life span.
What three (3) major issues does Developmental Psychology focus on?
1) Nature and Nurture:
How does our genetic inheritance (our nature) interact with our experiences (our nurture) to influence our development? How have your nature and your nurture influenced your life story?
2) Continuity and Stages:
What parts of development are gradual and continuous, like riding an escalator? What parts change abruptly in separate stages, like climbing rungs on a ladder?
3) Stability and Change:
Which of our traits persist through life? How do we change as we age?
Zygotes
The fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.
Embryo
The developing human organism from about 2 weeks after fertilizing through the second month.
Fetus
the developing human organism from 9 weeks after conception to birth.
Teratogens
(Literally, “Monster Makers”)
Agents such as Chemicals and Viruses, that can reach the embryo or fetus during prenatal development and cause harm.
Fetal Alcohol Syndrome (FAS)
Physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. In severe cases, signs include small, out-of-proportion head and abnormal facial features.
Habituation
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner.
Maturation
Biological growth processes that enable orderly changes in behavior, relative uninfluenced by experience.
(PS. Personally: I do NOT Agree)
Critical Period
An optimal period early in the life of a organism when exposure to certain stimuli or experiences produces normal development.
Cognitive Development
All the mental activities associated with thinking, knowing, remembering, and communicating.
Who is Jean Piaget?
A Swiss psychologist known for his work on child development in the 1920s.
Assimilation
Interpreting our new experiences in terms of our existing schemes.
Schemas
A concept of framework that organizes and interprets information.
Accommodation
In developmental psychology, adapting our current understandings (schemas) to incorporate new information.
Sensorimotor Stage
In Piaget’s theory, 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.
Object Permanence
The awareness that things continue to exist even when not perceived.
What is Baby Physics?
Like adults staring in disbelief at a magic trick (the “Whoa!” look), infants look longer at and explore an unexpected, impossible, or unfamiliar scene.
Preoperational Stage
In Piaget’s theory, 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 logic.
Conservation
The principal (which Piaget believed to be a part of concrete operational reasoning) that properties such as mass, volume, and number remain the same despite changes in the forms of objects.
