question 118

Multiple Choice

Why is it that older adults seem to have declines in their psychomotor speed and their working memories when compared to younger adults?​

• A) ​Because they experience a reduction in neurofibrillary tangles, which inhibits the ability of neurons to send messages at a maximally efficient speed.
• B) ​Because they experience a reduction in the ability of the corpus callosum to send messages from one cerebral hemisphere to the other.
• C) ​Because they experience more neuronal death in the diencephalon (the thalamus and hypothalamus), which hinders these cognitive skills.
• D) ​Because they show greater activation of the prefrontal cortex on easier tasks, thus "using up" their brain power before they ascend to more difficult tasks.
