Figure 12.

Overlap of the smooth kernel distributions of R² value values produced from fitting a first order polynomial to observed data from observers behaving in accordance with MVUE against the experimentally derived predictions of MVUE and MS (PSE in (a) and Sigma in (b)), and a set of observers behaving in accordance with MS against the experimentally derived predictions of MVUE and MS (PSE in (c) and Sigma in (d)). Red lines are for the 3 mm cue conflict and blue lines are for the 6 mm cue conflict. “OB” is the number of observers in each simulated experiment and “D” the magnitude of the cue conflict in mm. An overlap value of 1 (upper solid grey line) means that the distributions (examples shown in Figures 8e and f) completely overlap and are “fully confusable” and overlap of 0 means that the distributions do not overlap at all and are thus “not confusable.” The dashed grey line shows the case where the distributions overlap by 50%.
