Chapter 2 Flashcards
(130 cards)
In its most general psychological sense. It refers to certain changes that occur in human beings (or animals) between conception and death
Development
Changes in the body
Physical development
Changes in thinking, reasoning, and decision-making
Social Development
changes that occur naturally and spontaneously and to a large extent, genetically programmed
Maturation
things you’re born with, like your genes, biology, and natural growth
Nature
the environment you grow up in, like your family, culture, education, and surrounding
Nurture
cover on the axon accelerates transmission of impulses
Myelin
receive messages from other neurons
Dendrites
children this age have many more synapses than they will have as adult
Age 2 to 3
necessary and supports cognitive development. Researchers have found that some developmental disabilities are associated with a gene defect that interferes with this
pruning
Two kinds of overproduction and pruning processes take place:
Experience expectant
Experience dependent
because synapses are overproduced in certain parts of the brain during specific developmental periods,
awaiting (expecting) stimulation.
Experience-expectant
Here, synaptic connections are formed based on the individual’s experiences. New synapses are formed in response to neural activity in very localized areas of the brain.
Experience-dependent
accounts for about 85% of the brain’s weight in adulthood and contains the greatest number of neurons.
Cerebral cortex
allows the greatest human accomplishments, such as complex problem solving and language
Cerebral cortex
Controls higher-order thinking process.
Frontal lobe
major factor in language processing
Left hemisphere
handles much of our spatial-visual information and emotions (nonverbal information)
Right hemisphere
Here, the brain continues to develop, enhancing abilities to control behavior, organize, and manage impulsivity,
especially in low-stress situations.
During adolescence
Full brain maturity isn’t reached until?
Early 20’s
the brain continues to develop, during this period, enhancing abilities to control behavior, organize, and manage impulsivity, especially in low-stress situations.
Adolescents
which governs judgment and decision-making?
Prefrontal cortex
actively constructing understandings and actions.
Knowing
is based in our activities, and the brain is constantly changing
Knowledge
