The Brain And Cognative Development Chapter 3 Flashcards
Developmental perspective in which biological processes and environmental conditions influence the brains development: the brain has plasticity and is context dependant: and cognitive develops is closely linked with brain development
Neuroconstructivist view
Nerve cells, which are the nervous systems basic units
Neurons
The process by which the axon portion of the neuron becomes covered and insulated with a layer of fat cells, which increases the speed and efficiency of information processing in the nervous system
Myelination
Gaps between neurons, where connections between the axon and dendrites occur
Synapses
A large bundle of axon fibers that connect the brains left and right hemispheres
Corpus collosum
The highest level of the brains frontal lobes that is involved in reasoning, decision making, and self control.
prefrontal cortex
A lower subcortial system in the brain that is the seat of emotions and experience reawrds
limbic systme
A portion of the brains limbic system that is the seat of emotions such as anger
Amygdala
A mental concept or framework that is useful in organising and interpreting information
Schema
The incorporation of new information into existing knowledge
assimilation
An adjustment of a schema in response to new information
accomodation
A mechanisim in Piagets theory that explains how individuals shift from one state of thought to the next. The shift occurs as individuals experience cognative conflict or disequalillbrium intrying to understand the world. Eventually, the individual resovles the conflict and reaches a balance or equalibrium of thought
Equalilbration
This “judgment” region reins in
intense emotions but doesn’t
finish developing until at least
emerging adulthood.
Prefrontal cortex
These nerve fibers connect the brain’s
two hemispheres; they thicken in
adolescence to process information
more effectively.
Corpus callosum
Limbic system structure
especially involved in emotion.
Amygdala
A lower, subcortical system in the brain that is the seat of emotions and experience of rewards. This system is almost completely developed by early adolescence.
Limbic system
a recently developed field that focuses on
connections between development, socioemotional
factors, and neuroscience.
Developmental social neuroscience
the main architect of the field of
cognitive development, at age 27
Jean Piaget,
Infants gain knowledge of the world from the physical actions they perform on it. Infants coordinate sensory experiences with these physical actions. An infant progresses from reflexive, instinctual action at birth to the beginning of symbolic thought toward the end of the stage. Birth to 2 Years of Age
Sensorimotor Stage
PIAGET’S FOUR STAGES OF COGNITIVE DEVELOPMENT
The child begins to use mental representations to understand the world. Symbolic thinking, reflected in the use of words and images, is used in this mental representation, which goes beyond the connection of sensory information with physical action. However, there are some constraints on the child’s thinking at this stage, such as egocentrism and centration. 2 to 7 Years of Age
Preoperational Stage
PIAGET’S FOUR STAGES OF COGNITIVE DEVELOPMENT
The child can now reason logically about concrete events, understands the concept of conservation, organizes objects into hierarchical classes (classification), and places objects in ordered series (seriation). 7 to 11 Years of Age
Concrete Operational Stage
PIAGET’S FOUR STAGES OF COGNITIVE DEVELOPMENT
The adolescent reasons in more abstract, idealistic, and logical (hypothetical-deductive) ways. 11 Years of Age Through Adulthood
Formal Operational Stage
