developmental psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span
zygote
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 fertilization through the second month
fetus
the developing human organism from 9 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, signs include a 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, relatively uninfluenced by experience
cognitive
all the mental activities associated with thinking, knowing, remembering, and communication
schemas
a concept or framework that organizes and interprets information
asssimilate
interpreting our new experiences in terms of our existing schemas
accomodation
adapting our current understandings(schemas) to incorporate new information
Who pioneered the 4-stage cognitive development model?
Jean Piaget
What are Piaget’s stages of Cognitive Development?
Sensorimotor, Preoperational, Concrete Operational, Formal Operational
Sensorimotor stage
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.
Coordination of senses with motor responses, sensory curiosity about the world. Language used for demands and cataloguing. Object permanence is developed
Object permanence
the awareness that things continue to exist even when not perceived
Preoperational stage
from about 2 to about 6-7 years of age, during which a child learns to use language but does not yet comprehend the mental operations of concrete logic.
symbolic thinking, use of proper syntax and grammar to express concepts. Imagination and intuition are strong, but complex abstract thoughts are still difficult. Conservation is developed.
conservation
the principle that properties such as mass, volume, and number remain the same despite the changes in the form of objects
egocentrism
in Piaget’s theory, the preoperational childs’s difficulty taking another’s point of view
theory of mind
people’s ideas about their own and other’s mental states- about their feelings, perceptions, and thoughts, and the behaviors they might predict
concrete operational
in Piaget’s theory, the stage of cognitive development(from about 7-11 years of age) during which children gain the mental operations that enable them to think logically about concrete events
conservation!
Formal operational
in Piaget’s theory, the stage of cognitive development(normally beginning about age 12) during which people begin to think logically about abstract concepts
animism
the belief that natural phenomena or inanimate objects are alive or possess lifelike characteristics, such as intentions, desires, and feelings.
pretend play
the stage of play engaged in by children who are capable of assigning action to symbolic objects. Children will take on roles, assign meaning to objects, and transform their reality into a world of its own.
hierarchical classification ability
the ability to simultaneously sort things into general and more specific groups, using different types of comparisons. Most children develop hierarchical classification ability between the ages of 7 and 10.
reversibility
a mental operation that reverses a sequence of events or restores a changed state of affairs to the original condition.
autism spectrum disorder
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
Stranger anxiety:
the fear of strangers that infants commonly display, beginning by about 8 months of age.
