Evidence for the Role of the Brain in Working Memory

Evidence for the role of the brain in working memory comes from studies that show:

A) interference with central executive control prevents access to long-term memory.
B) damage to the frontal cortex interferes with a monkey's ability to perform the delayed match-to-sample task.
C) damage to the occipital cortex interferes with the formation of images in the visuospatial sketchpad.
D) removal of a small amount of tissue in the temporal lobe destroys working memory.
