Wk. 2 - Infancy and Early Childhood - Ch. 5 - Physical and Cognitive Development in Early Childhood Flashcards
myelination
The process by which axons are covered and insulated with a layer of fat cells, which increases the speed of which information travels through the nervous system.
preoperational stage
Piaget’s second stage, lasting about 2 years to 7 years of age, during which children begin to represent the world with words, images, and drawings, and symbolic thought goes beyond simple connections of sensory information and physical action, stable concepts are formed mentally reasoning emerges, egocentrism is present, and magical beliefs are constructed.
operations
In Piaget’s theory, these are internalized, reversible sets of actions that allow children to do mentally what they formerly did physically.
symbolic function substage
Piaget’s first substage of preoperational thought, in which the child gains the ability to mentally represent an object that is not present (between about 2 years and 4 years of age).
egocentrism
The inability to distinguish between one’s perspective and someone else’s (salient feature of the first substage of preoperational thought).
aninism
The belief that inanimate objects have lifelike qualities and are capable of action.
intuitive thought substage
Piaget’s second stage of preoperational thought, in which children begin to use primitive reasoning and want to know the answers to all sorts of questions (between about 4 years and 7 years of age).
centration
The focusing of attention on one characteristic to the exclusion of all others.
conservation
In Piaget’s theory, awareness that altering an object’s or a substance’s appearance does not change its basic properties.
social constructivist approach
An approach that emphasizes the social contexts of learning and that knowledge is mutually built and constructed. Vygorsky’s theory reflects this approach.
zone of proximal development (ZPD)
Vygorsky’s term for tasks that are too difficult for children to master alone. but can be mastered with assistance.
executive function
An umbrella-like concept that consists of a member of higher-level cognitive processes linked to the development of the brain’s prefrontal cortex. Executive function involves managing one’s thoughts to engage in goal-directed behavior and to use self-control.
theory of mind
Refers to the awareness of one’s own mental processes and the mental processes of others.
morphology
Units of meaning involved in word formation.
syntax
The ways words are combined to form acceptable phrases and sentences.
