Fig. 5: Material-weight illusion data and fits.
From: Weight illusions explained by efficient coding based on correlated natural statistics
Black circles indicate mean relative bias (A) and mean within-participant SD (B) of human observers (n = 25) in estimating the mass of lifted objects with different surface materials but identical mass and volume23. Error bars indicate ± 1 within-subject SEM. Red lines show predictions of the fitted efficient coding model.
