People with attention-deficit/hyperactivity disorder often have problems because they are impulsive and inattentive. The component of working memory that is most likely to be relevant in these problems is
 
  a. the episodic buffer.
  b. the central executive.
  c. the visuospatial sketchpad
  d. the phonological loop.

Question 2

In the working-memory model, which of the following cognitive activities would the central executive be most likely to perform?
 
  a. representing the information from a geometry problem
  b. deciding which items on a list should be remembered and which should be forgotten.
  c. actively transferring the information from working memory into sensory memory
  d. listening to a series of words in random order.

Question 3

Chapter 4 discusses neuroscience research on the central executive. According to this discussion, the central executive
 
  a. is primarily controlled by brain structures located below the cortex.
  b. is primarily controlled by brain structures at the back of the cortex.
  c. is primarily controlled by portions of the frontal lobe.
  d. apparently does not have a consistent connection with any part of the brain, at least according to the current research.

Question 4

According to the Baddeley's revised model of working memory, one major purpose of the episodic buffer is to
 
  a. store musical information (such as pitch and tones) for brief periods of time.
  b. manage the decisions that are too complicated for the central executive.
  c. coordinate the meaning and the visual appearance of written text.
  d. provide temporary storage for information from long-term memory, the phonological loop, and the visuospatial sketchpad.
