Waugh and Norman used a probe memory scan task in which subjects recalled a test digit following a probe. They found that the probability of recalling the test digit was determined by
 
  a. the rate of presentation, supporting an interference theory.
  b. the rate of presentation, supporting a decay theory.
  c. the number of interfering items, supporting an interference theory.
  d. the number of interfering items, supporting a decay theory.

Question 2

Waugh and Norman's Short-Term Memory (STM) study separated the effects of decay from the effects of interference by independently manipulating
 
  a. the number of intervening digits independently of the amount of time that elapsed between the digits.
  b. the intensity of the stimulus independently of its duration.
  c. the phonetic similarity of the digits independently of rehearsal time.
  d. the amount of study time independently of the retention interval.

Question 3

In proactive interference,
 
  a. information in STM interferes with information in LTM.
  b. information in the sensory store interferes with information in LTM.
  c. previously presented information interferes with subsequent learning.
  d. recently learned information interferes with prior learning.

Question 4

Peterson and Peterson estimated that the duration of short-term memory (STM) was approximately
 
  a. 3 seconds. c. 60 seconds.
  b. 18 seconds. d. 90 seconds.

Question 5

Which of the following is not a control process with short-tem memory as proposed by Atkinson and Shiffrin?
 
  a. rehearsal c. decisions
  b. coding d. identification
