Developmental Psychology Flashcards
a branch of psychology that studies physical, cognitive, and social change throughout the life span
developmental psychology
the fertilized egg; it enters a 2 week period of rapid cell division and develops into an embryo
zygote
the developing human organism from about 2 weeks after fertilization through the second month
embryo
the developing human organism from 9 weeks after conception to birth
fetus
(literally, “monster makers”)
agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
teratogens
physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking; in severe cases, signs include a small, out-of-proportion head and abnormal facial features
fetal alcohol syndrome (FAS)
decreasing responsiveness with repeated stimulation; as infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner
ex: a fetus adapts to a vibrating device placed on the mother’s abdomen; over time it seems to get bored of the action
habituation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
maturation
all the mental activities associated with thinking, knowing , remembering, and communicating
cognition
a concept or framework that organizes and interprets information
ex: attributes associated with a certain word; when you think of your best friend you may think kind, funny, sympathetic, etc
schema
interpreting our new experiences in terms of our existing schemas
ex: when a child learns what a dog is, they begin calling all four-legged animals a dog
assimilation
adapting our current understandings (schemas) to incorporate new information
ex: by adding new characteristics to distinguish dogs from cats and other four-legged animals, we increase our cognitive understanding
accommodation
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
ex: taking 5 senses into account: touching, grasping, mouthing
-issues with stranger danger
-object permanence developing
sensorimotor stage
the awareness that things continue to exist even when not perceived
ex: 3 month old Bobby lacks this ability; every time his mother or father leaves the room he cries because he thinks they are gone
object permanence
in Piaget’s theory, the stage (from about 2 years to 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
ex: able to represent things with words and images but too young to perform mental operations; a 5 year old cannot understand that two differently sized glasses could contain the same amount of milk (lacks concept of conservation)
preoperational stage
the principle (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
ex: Sally watches as two identical glasses are filled with the same amount of milk; when the milk in one glass gets poured into a taller glass, she can’t understand it’s still the same amount
conservation
in Piaget’s theory, the preoperational child’s difficulty taking another’s point of view
ex: Allie, age 4, shows her grandfather her two matching cards while playing a game- yet they are still facing her; because she can see them, she believes he can as well
egocentrism
people’s ideas about their own and others’ mental states- about their feelings, perceptions, and thoughts and the behaviors these might predict
ex: children come to understand what made a playmate angry, when a sibling will share, and what might make a parent buy a toy; they begin to tease, empathize, and persuade
theory of mind
in Piaget’s theory, the stage of cognitive development (from about 7-11 years old) during which children gain the mental operations that enable them to think logically about events
ex: understanding and simplifying math equations, comprehending more complicated jokes, improving concept of conservation
concrete 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
ex: imagining realities and symbols, ponder hypothetical propositions and consequences, moral reasoning
formal operational thinking
a framework that offers children temporary support as they develop higher levels of thinking
ex: by giving children new words and mentoring them, parents, teachers, and other children provide a step to help children attain higher cognitive development/better thinking
scaffold (ing)
a disorder that appears in childhood and is marked by significant deficiencies in communication and social interaction, and by rigidly fixated interests and repetitive behaviors
ex: can’t tell others’ emotions or thoughts well, trouble socializing
autism spectrum disorder (ASD)
the fear of strangers that infants commonly display, beginning by about 8 months of age
stranger anxiety
an emotional tie with another person; shown in young children by their seeking closeness to their caregiver and showing distress on separation
attachment
an optimal period early in the life an organism when exposure to certain stimuli
ex: baby chicks’ period falls shortly after they have hatched when the first moving object they see is their mother; they will follow her from now on
critical period
