Experiment 2. Eye movement traces and fixations (white diamonds) for one participant subsequently designated as aware (top panels) and for another participant designated as unaware (bottom panels) of the manipulation that occurred in block 3. In both cases, the scene was novel in block 1 (left panels), it was repeated in block 2 (center panels), and it was repeated in block 3 but with a manipulation introduced into the manipulated region (right panels). In block 3, the participant who was aware of the manipulation directed a greater proportion of her fixations to the manipulated region than the participant who was unaware of the manipulation. In each panel, the manipulated region is identified by a black square, but the square did not appear during the experiment (eye movements appeared to move beyond the scene when a participant blinked during the 5 s scene presentation).
