Figure 1

Notice that the empty circle representing the “new object” on Day 1 (D0 post-drug) becomes the “old object” on days 3 (D2 post-drug), 5 (D4 post-drug), and 7 (D6 post-drug), when it is combined with the “new object” (filled in shapes). Injections were given 30 min before the first test session.
