Average psychometric functions for single-object and dual-object report for congruent judgment frames, from Experiments 1A and 1B. (top panels) Psychometric functions for Experiment 1A using vertical base angles in zero (left) and high (right) external noise. (bottom panels) The same psychometric functions for Experiment 1B using horizontal base angles for judgment. Note the different scale of the contrast threshold axis in zero noise (0 to 0.4) and high external noise (0 to 1.0). Error bars (some smaller than the symbols) correspond to the 85% confidence intervals based on binomial variability. The dual-object report deficit was not significant for individual observers by Weibull tests. Smooth curves show the fits of a perceptual template model (see text).
