Given two taps on the skin at the same position and a third tap some distance away, an observer reports the second tap as occurring at a position between the first and third taps. This is the saltation phenomenon, and as presented in this theoretical note, it is a phenomenon which is easily accommodated by a theoretical rotation of space-time axes.
A mathematical model for assimilation and contrast in the perception of extent is presented, and predictions generated from the model are empirically tested. Implications of the model for the Müller-Lyer illusion are dealt with explicitly, and implications of the model for the Delboeuf, Ebbinghaus, and other illusions of extent are discussed in general(More)

The current investigation extended these findings(More)
