Validation of the behavioral types. Scatter plots of (A) individual scores and (B) variable loadings from the PLS-DA (n = 62, one significant component: R²X = 0.359, R²Y = 0.343, Q² = 0.277; a second, non-significant component was added to obtain a two-dimensional model for visualization: R²X = 0.080, R²Y = 0.143, Q² = –0.046) of the MCSF parameters (X) by behavioral type (Y). BE, bridge entrance; CTRCI, central circle; D, duration; DCR, dark corner room; Dist, distance; F, frequency; M, MCSF; TOTACT, total activity; TOTCORR, total corridor; Vel, velocity.
