Figure 1 Examples of the Stimuli Used in Our Experiments (A–C) Computer-generated images rendered from the same 3D object. (A) and (B) are rendered from different light fields but look similar. (C) looks matte and very different from (B), but the image difference between (B) and (C) is smaller than the difference between (A) and (B).

Figure 2 Stimuli and Experimental Results (A) Surface change stimulus. (B) Light-field change stimulus. (C) Illustration of the streams of changing images. In both displays, the object image was flashed for a duration of 700 ms. The ISI was 200 ms. (D) Mean percentage of looking time for changing images. The light red and blue show the results for the surface and light-field change, respectively. Each data point shows the average for infant observers. The error bars represent SE. Asterisks indicate the significance level of statistical differences: ∗∗p < 0.01. (E) Individual data showing percentage of looking time for changing images. The horizontal axis represents age in days. The red circles and the blue squares show the results for the surface and light-field change, respectively. The red line is the regression line fitted to the red circles. The blue line is the regression line fitted to the blue squares. (F) Mean percentage of looking time for both (surface and light-field) changing images. See also Figures S1 and S2, Tables S1 and S2, and Movies S1, S2, S3, and S4.
