Table 1.

Left, Summary statistics of three measures for the Necker experiments in the FX, RW, and LJ motion conditions; inertia with respect to (w.r.t.) stimulus center of gravity ($I_{\text{stimulus}}$), inertia w.r.t. fixation center of gravity ($I_{\text{fixation}}$), and MPC (${\rho }^{*}$). For each condition in the Necker experiment, median values over participants’ data are given with median absolute deviation following the $\pm$ sign. Right, Approximate Friedman test results (${\chi }^2;p$) and size effect ($W$) are given.
