The size-weight illusion in 2-D nonlinear psychophysics

Abstract: An extension of unidimensional nonlinear psychophysics is postulated by using forms of cross-coupling between the parameters of the two single-channel recursions, which have already been shown to model some perceptual phenomena. The size-weight illusion is shown to be reproducible in the topology of its relations, and it is suggested that some so-called illusions are in fact the natural consequences of nonlinear cross-coupling. The conditions that produce the illusion involve partially compensating the cross-c… Show more

“…These regions are of potential interest because they may be interpreted as evidence of system dynamics where there is sensory overload and a predictable breakdown of normal functioning. They are of mathematical interest, in comparison with results in other simpler or better known recursions (Livi et al, 1988;Gumowski and Mira, 1980) which have been mapped. We report here an exploratory analysis of some Julia sets and Mandelbrot-type sets; computational problems are noted.…”

“…Its properties within a stable region have been shown to reproduce a diversity of empirical phenomena which are of interest to experimental psychologists (Gregson, 1989a, b;Gregson and Britton, 1989). The ranges of parameter values in the model which are appropriate for the simulation of psychophysical data have been illustrated for several examples in the references given.…”
