Hruska and Colleagues Had Expert and Novice Doctors Read Clinical

Hruska and colleagues had expert and novice doctors read clinical cases and reason about the appropriate treatment while undergoing fMRI neuroimaging. Their results suggested that

B) experts and novices showed equal activation in the prefrontal cortex.
C) neither experts nor novices showed activation in the prefrontal cortex.
D) expert doctors possessed more sophisticated long-term memory knowledge that reduced the burden on their working memory systems.
