The size-weight illusion and beyond: A new model of perceived weight
Fig 5
(A) Schematic of the model’s 5 components. The perceived weight of an object is positively correlated with both objects’ weights (components 1 and 3), and the judged object’s density (component 2). When the objects’ weights are similar (captured by a Gaussian over their difference) the two objects’ densities have an additional influence (components 4 and 5). The importance of each component is conveyed by the thickness of the corresponding arrow. (B) Variance in perceived weight explained by the addition of each component to the constant in the model (bars) and corresponding SSR (magenta lines and markers) (C). The order of components follows the maximum increase in R2 with each addition (see Table A in S2 Supporting Information). X = .
