Results of Experiment 1: Color and Motion (Rotation Speed) Salience Calibration. Graphed here is infants’ preference for the comparison object as a function of comparison color or speed. Color comparisons were categorical. In the case of speed, the data were fit with a cumulative normal function to allow for interpolation. The vertical axis represents the percentage of trials where the comparison was preferred to the baseline (green star rotating at 22.5 deg/s). We found that preference for the color comparison was 68% for blue, 73% for purple and 79% for red. Preferences for the speed comparisons were as follows: 77% for 68 deg/s; 85% for 113 deg/s: 90% for 158 deg/s: 89% for 203 deg/s; and 90% for 248 deg/s. The 79% preference level, which we used as our JSD (Just Salient Difference, see main text) level, is shown by the grey line.
