Figure 4.
Mean proportion of attempts at each aperture group for (A) Experiment 1, (B) Experiment 2 and (C) Experiment 3. Attempts are normalized to each participant’s affordance threshold, denoted by the solid vertical line at 0 cm, for each condition. On the x-axis, passable apertures are represented by positive numbers to the left of the affordance threshold, and impassable apertures are represented by negative numbers to the right of the affordance threshold. Error bars denote standard errors.
