Top: Examples of same and different trial displays. Middle: The 32 pictures of the 32-item training set. Numbers on left indicate cumulative rows of pictures used for the 8-item, 16-item, and 32-item training sets. Bottom: Four examples of same and different pairs (from 30 pairs of each type) used to test transfer following acquisition with the 32-item set. The complete set of transfer pairs used in this test, along with those of other tests, and other training stimulus sets can be seen in color in Wright & Katz (2006).
