Results for Experiment 1. Threshold contrast energy as a function of the center-to-center spacing between targets and flankers. Results for the different observers are presented in different columns. On the right ordinate are data points for the unflanked target (infinite spacing). The star symbol indicates the flanker energy. Letter thresholds are presented in the upper plots, while object thresholds are presented in the lower plots. Error bars are ±1 SE and some are smaller than the plot symbols.
