Figure 12.

Model predictions and data for the egocentric distance-matching task of Experiment 1. In the left panel, the solid line represents the angular expansion hypothesis prediction for exocentric depth extent matching based on Equation 2 of Appendix A, which has no free parameters; the relevant observed data are the solid circles. The dashed line represents the prediction of the model for frontal extents; the single unknown parameter in this model has been set based on the results of Li et al., (2011); the relevant observed data are the open circles. In the right panel, the predicted anisotropy (ratio between perceived frontal and depth extents) for each exocentric distance is shown.
