Life Span Chapter 8

Rodesia is a left-handed adult. Is is most likely that she

has thicker corpus callosum This is probably because, growing up in a right-handed world, left-handers have a greater need to coordinate both sides of the body

Children of African descent tend to be tallest, followed by European's Asian, and Latinos.

2)During childhood, the legs develop rapidly. T/F

F During childhood, the brain develops faster than any other part of the body

Myelination is essential for basic communication between neurons. T/F

F Although myelination is not essential for basic communication between neurons, it is essential for fast and complex communication.

7)Most serioius childhood injuries truly are "accidents." T/F

F Most serious accidents involve someone's lack of forethought

Which of the follwing is true of the corpus callosum?

It connects the two halves of the brain. The corpus callosum is not directly involved in memory. Myelination of the central nervous system is important to the master of fine motor skills

3 yrs old Kyles' parents are concerned because Kyle, who generally seems healthy, doesn't seem to have the hefty appetite he had as an infant. Should they be worried?

No, because caloric need is less during early childhood than during infancy

13) Andrea is concerned because her 3 yr old daugher has been having nightmares. Her pediatrician tells her

Not to worry, because nightmares are often caused by increased activity in the amygdala which is normal during early childhood. Nightmares generally occur when activity in the amygdala overwhelms the slowly developing prefrontal cortex. There is no indication that nightmares are caused by diet Increased activity in the amygdala is normal during early childhood, as are the nightmares that some children experience.

8)Children often fare as well in kinship care as they do in conventional foster care. T/F

T

10) Children who have been maltreated often regard other children and adults as hostile and exploitative.

They are less friendly and more aggressive They are more isolated than other children 11 Brain areas that control generalized creative and emotional impulses are found in the right hemisphere.

Study tip: Learning and remembering developmental changes in height, weight, brain maturation, and other aspects of biosocial development requires a lot of rote memorization. A good way to facilitate your learning is to design and complete a simple organizational chart. Your chart might look something like:

Weight: Children gain 4/5pounds each year. Because they are also growing rapidly, they are actually thinner than in earlier years.
