MBB-Exam 2 Questions With Verified
Solutions
In our development lecture, we discussed the idea that brain architecture is built in hierarchical,
bottom-up sequence. This refers to the fact that:
Higher capacities set the basis for development of more basic cognitive processes and reflexes. (?)
Cortical Specificity refers to
The differentiation of the cerebral cortex into functional areas (e.g. cognitive, perceptual, motor
functions)
Research suggests that we have the most potential for synaptic connections when we are
a fetus
Within the visual cortex, the generation of synapses appears to begin around birth and peak at _____
when it hits 150% of adult levels before it starts decreasing
The end of the first year/fifth year (?)
In our reading on the Teen Brain, it is noted that studies of children and adolescents have found that
_______ can increase impulsive behavior; some researchers report finding that it is a factor in
delinquency
Sleep deprivation
One might expect a 80 year old to perform better than a 20 year old on a task that assesses
-spatial orientation (?)
-processing speed (?)
-vocabulary (?)
In the presentation on development and whether or not one can damage or supplement brain
development, we discussed a population who has been shown to be an example of what happens
when development is negatively affect early in life and has lifelong effects. This population is
orphans who were emotionally neglected
The ____________, associated with reasoning and decision making, undergo significant changes
during adolescence, but do not fully develop until the mid 20's
frontal lobes
The limbic reward system is part of the _____________, which are thought to mature during the late
teen years (18-19)
temporal lobes
Methamphetamine use during adolescence has been associated with
loss of volume in the limbic reward structures
Aging research suggests that the single most feared aspect of growing old is
cognitive decline
