Dr. Broca wants to measure the intelligence of children between the ages of 6 and 11 years old. Assuming he can put the brains back into their heads with no harm to the children, which of the following methods will give him the most accurate results?
A) Weighing the brains
B) Measuring the size (or volume) of the brains
C) Inspecting the rate at which the synapses are being generated and pruned
D) Measuring the thickness of the frontal and temporal lobes
Question 2In a longitudinal study (Shaw and colleagues, 2006 ) that charted brain development in children with average, high, and superior IQ scores, researchers found that
A) children with superior IQ scores already had thicker cortices than the children in the other groups by age 7.
B) children with superior IQ scores showed a rapid increase in gray matter that continued throughout adolescence.
C) children with average IQ scores showed the least decline in gray matter during adolescence.
D) the difference in growth patterns of gray matter for the three groups was most pronounced in the temporal regions.
Question 3One difference in boys' and girls' brains during middle childhood is that
A) boys experience greater development in neural networks involved in spatial-visual discrimination.
B) boys experience greater development in neural networks involved in both fine and gross motor movements.
C) girls experience greater development in neural networks involved in gross motor movements.
D) girls' brains are 10 percent larger.
Question 4Which of the following correctly describes the pattern of growth of gray and white matter in early childhood?
A) Both types of matter show an inverted-U shape.
B) Both types of matter increase linearly.
C) The gray matter increases linearly, but the white matter follows an inverted-U shape.
D) The white matter increases linearly, but the gray matter follows an inverted-U shape.
Question 5When he was younger, 6-year-old Mark had trouble hiding his disappointment when he failed to get exactly what he wanted, so he constantly threw temper tantrums. The fact that he can now control his emotions better is primarily due to an increase of gray matter in which brain lobes?
A) Frontal
B) Occipital
C) Parietal
D) Temporal
Question 6What is the process through which the left and right hemispheres of the brain begin to specialize for particular functions?
A) Synaptogenesis
B) Competitive elimination
C) Lateralization
D) Myelination
