Example stimuli used in the Experiments. Fractal ‘forest’ stimuli used in Experiment 1 of differing D-values where D = 1.2 (A), 1.4 (B), 1.6 (C), and 1.8 (D). On the left side of each panel in (A–D) are images of the original forest pattern. On the right side of (A–D) are images of randomized versions of the original forest patterns, where the same forest has been divided into tiles and the tiles randomized. Fractal ‘tree’ stimuli used in Experiment 2 (E) of D-values of 1.2, 1.4, 1.6, and 1.8, from the left to right side of the panel.
