Chapter 2: Cognitive and Linguistic Development Flashcards
cognitive development
Development of increasingly sophisticated thinking, reasoning, and language with age.
developmental milestones
Appearance of a new, more advanced behavior that indicates significant progress in a child’s development.
maturation
Gradual, genetically driven acquisition of more advanced physical and neurological capabilities over the course of childhood and adolescence.
sensitive periods
Age range during which environmental conditions have an especially strong influence on an aspect of a child’s development (you may sometimes see the term critical period).
biological systems theory
Theory proposing that a child’s everyday environments and the child’s broader social and cultural contexts interact in their influences on the child’s development.
culture
Behaviors and belief systems that members of a long-standing social group share and pass along to successive generations.
neurons
Cell in the brain or another part of the nervous system that transmits information to other cells.
glial cells
Cell in the brain that supports neurons or general brain functioning.
synapses
Junction between two neurons that allows transmission of messages from one to the other.
neurotransmitters
Chemical substance through which one neuron sends a message to another neuron.
cortex
Upper part of the brain; primary site of complex, conscious thinking processes.
synaptogenesis
Universal process in brain development in which many new synapses form spontaneously.
synaptic pruning
Universal process in brain development in which many previously formed but rarely used synapses gradually wither away.
myelination
Growth of a fatty sheath (myelin) around the axons of neurons, enabling faster transmission of electrical impulses.
plasticity
Ability to reorganize in order to adapt to changing circumstances; term often used in describing the human brain.
cognitive tools
Concept, symbol, strategy, procedure, or other culturally constructed mechanism that helps people think about and respond to situations more effectively.
appropriation
Process of internalizing but also adapting the cognitive tools of one’s culture for one’s own use.
cognitive apprenticeship
Mentorship in which an expert and novice work together on challenging tasks, with the expert providing guidance regarding how to think about the tasks.
schemes
Organized group of similar actions or thoughts that are used repeatedly in response to the environment.
equilibrium
State of being able to address new events with existing schemes.
equlibration
Movement from equilibrium to disequilibrium and back to equilibrium, a process that promotes development of more complex thought and understandings.
formal operations stage
Piaget’s fourth and final stage of cognitive development, in which logical reasoning processes can be applied to abstract ideas as well as to concrete objects.
formal operational egocentrism
Inability of adolescents in Piaget’s formal operations stage to separate their own abstract logic from the perspectives of others and from practical considerations.
