brain
Which of the following is least likely to be used to measure an infant’s brain activity?
sonogram
Which of the following is true of the human brain?
It has two hemispheres
The rapid development of the brain in infancy can be attributed to the
cephalocaudal principle.
Which lobes in the brain are associated with personality and thinking?
frontal lobes
In infancy, growth spurts may occur in a single day and alternate with long time frames of little or no growth for days and weeks.
true
One analysis found that ______ were the most frequent perpetrators of shaken baby syndrome.
fathers
Infant brain mapping is being used to assess perceptual and cognitive activities including which of the following?
language
vision
hearing
The most accurate statement regarding creativity and complex thinking in most people is
Complex thinking includes creativity and is the outcome of communication between both hemispheres of the brain.
User
Each hemisphere of the brain has four major areas called ____
lobes
Neurons are Blank______ cells that send electrical and chemical signals.
nerve
Carter has a sensory disorder in which he has difficulty understanding where his body is in relation to others. He frequently stands too close, leans unintentionally, or bumps into others. Which lobes in the brain could this spatial difficulty be attributed to?
parietal lobes
The process by which nerve cells are coated with insulation that enhances the speed and efficiency of the information traveling through the nervous system is known as
myelination
The expansion of dendritic connections in infant development results in
new neural pathways
The concept that refers to the specialization of function in one hemisphere of the cerebral cortex is
lateralization
______ is the term used to describe the process by which unused neural connections are replaced by other pathways or disappear.
pruning
Generally, the axon carries signals away from the cell body, and the ___ carry signals toward the cell body.
dendrites
In the prefrontal cortex, the density of synapses is not attained until
emerging adulthood
The layer of fat cells that encases many axons is called the
myelin sheath
Based on our understanding of the impact of environment on brain development, children raised in an unresponsive, unstimulating, and underfunded orphanage would likely have the most depression in brain activity. Therefore, the correct choice is:
children raised in an unresponsive, unstimulating, and underfunded orphanage
In infancy, growth spurts may occur in a single day and alternate with long time frames of little or no growth for days and weeks.
true
The premise of the neuroconstructivist view that is not listed among the options is:
Developmental processes occur independent of environmental experiences.
Which of the following is not a premise of the neuroconstructivist view?
The development of the brain is closely linked with cognitive development.
Synaptic connections that are unused are typically:
replaced or pruned.
Sleep is essential for the human body to do the following:
increase cell production
remove waste in neural tissues
increase synaptic connections
improve memory
The true statement regarding myelination is:
Auditory myelination is not completed until 4 or 5 years of age.
Children who grow up in an unresponsive and unstimulating environment typically show considerably less brain activity compared with children with stimulating backgrounds.
true
User
The typical newborn sleeps Blank______ a day.
18 hours
The most common infant sleep-related problem is
nighttime waking
The neuroconstructivist view emphasizes the importance of interactions between biological processes and
environmental experience
Losing just a few hours of Blank______ can have negative effects on attention, reasoning, and decision making.
sleep
In the prefrontal cortex, the density of synapses is not attained until
adolescence

Which of the following statements about newborn sleep are true?
The typical newborn sleeps approximately 18 hours a day.
Sleep totals for newborns are variable and can range from 10 to 21 hours per day.
According to the World Health Organization (WHO), infants 0 to 3 months of age should get 14 to 17 hours of good-quality sleep daily.
The following have been associated with shorter duration of infant sleep:
maternal depression during pregnancy
early introduction of solid foods
child-care attendance
infant TV viewing
Based on the fact that the participant began the sleep cycle with REM sleep and spent 50 percent of the time in REM sleep, it would suggest that the subject is most likely an
infant
The view that states that environmental conditions and biological processes influence development is
the neuroconstructivist view
Sleep is essential for the human body to do the following:
remove waste in neural tissues
improve memory
increase synaptic connections
increase cell production
Some researchers believe that infants spend so much time in REM sleep because it provides them with added Blank______ since they spend less time awake than older children do.
self-stimulation
The statement that is true about REM sleep in infancy is:
It often begins an infant’s sleep cycle.
The true statement about SIDS (Sudden Infant Death Syndrome) is:
SIDS is the most frequent cause of infant death in the United States.
Infants are able to begin to feed themselves because of advances in their
fine motor control
Losing just a few hours of Blank______ can have negative effects on attention, reasoning, and decision making.
sleep
One study found that low maternal sensitivity when infants were 15 and 24 months of age was linked to
higher risk of obesity in adolescence
In the prefrontal cortex, the area of the brain where higher-level thinking and self-regulation occur, the density of synapses is not attained until
adolescence
