  from all three lists. This is a standard free
  recall task, so feel free to write them in any
  order.

Data Analysis

• The real goal of this demonstration was to give
  you varying amounts of maintenance (Type I)
  rehearsal and see what effect that would have on
  memory.
• Some words were only to be rehearsed for one
  position (one second) up to five positions (five
  seconds).
• What difference might this make?

68
Data Analysis

• If more rehearsal leads to better recall

69
Data Analysis

• If more rehearsal doesnt affect recall
