Cognitive Developement in childhood Flashcards
concrete operation stage
Piagetian stage between 7and 12 when children can think logically about concrete situations but not engage in scientific reasoning
conservation problems
problems pioneered by Piaget in which physical transformation of an object changes a perceptually salient dimension but not the quantity that it is being asked about
continuous development
ways in which development occurs in a gradual incremental manner, rather than sudden jumps
depth perception
ability to actively perceive the distance from oneself of objects in the environment
formal operations stage
Piagetian stage at 12 yrs and up, in which adolcentants may gain the reasoning powers of educated adults
information processing theories
theories that focus on describing the cognitive process that underlies thinking at and age cognitive growth over time
nature
genes that children bring with them to life and that influences all aspects of their development
numerical magnitudes
the sizes of numbers
nurture
the environment, starting in the womb, that influence all aspects of their development
object permanence task
Piagetian task in which infants below 9 months of age fail to search for an object that is removed from their sight, they act as though it no longer exists
phonemic awareness
awareness of the component sounds within words
Piaget’s theory
a theory that development occurs through a sequence of discontious stages; the sensormotor, preoperational, concrete operational, and formal operational stages
preoperational reasoning stage
period within Piagetian theory from age 2-7 yrs, in which children can represent objects through drawing and language but cannot solve logical reasoning problems.
qualitative changes
Large, fundamental change, as when a caterpillar changes into a butterfly.
stage theories that each stage reflects qualitative change relative to previous stage
quantitive changes
gradual, incremental change, as in the growth of pine trees girth
